[KDE bloat](/blog/2021/06/04/myth-bloat.html), [WMs rule](/blog/2020/12/26/why-wms-suck.html). Therefore, we must use get rid of the DE in KDE and we are left with... everyone's favorite WM, [KWin](https://userbase.kde.org/KWin)!
|
||||
|
||||
There are only three easy steps. First, set up the environmental variables and start up D-Bus:
|
||||
|
||||
```sh
|
||||
export $(dbus-launch)
|
||||
export QT_QPA_PLATFORM=wayland
|
||||
```
|
||||
|
||||
Now enjoy your super unbloated standalone compositing Wayland window manager with `kwin_wayland konsole`. Need [XWayland](/blog/2020/04/21/wayland-is-a-scam.html)? To add that extra bloat, just pass the `--xwayland` flag.
|
||||
|
||||
|
||||
|
||||
All set! Now you can flex your very unbloated WM in all of its glory. It's Wayland, too! Now try getting some work done...

title: "How to Break a Rolling Release"

It's the day! Plasma 5.21 is out!
|
||||
|
||||
First, let me flex my `neofetch` to answer all your burning questions about my OS:
|
||||
|
||||
|
||||
|
||||
Now, time for the update. The big one. The closest thing to a point update in a rolling release. And...
|
||||
|
||||
|
||||
|
||||
Lots of updates, but Plasma 5.21 is not one of them.
|
||||
|
||||
Digging a bit deeper, it looks like it's still in [testing](https://wiki.archlinux.org/index.php/Official_repositories#Testing_repositories). Looks like we need to enable it first. Hopefully my computer doesn't explode or something when I do this...
|
||||
|
||||
|
||||
|
||||
There we go! Looks like Linux 5.11 is part of this sweet deal too! Let's break our rolling release! I mean, what could go possibly wrong? It's *only* 1263.42 MiB of packages. And I don't have a backup ready. Great!
|
||||
|
||||
A few minutes and a reboot later...
|
||||
|
||||
OK, the boot looks good, no black screens or anything. Plasma (looks like the X11 session got renamed from Plasma to Plasma X11) on X started up extra fast... and we're in!
|
||||
|
||||
|
||||
|
||||
Some first impressions: The new Breeze Twilight theme looks awesome! I love hybrid light-dark themes! The application launcher is also organized a lot better now.
|
||||
|
||||
|
||||
|
||||
The system monitor app looks pretty good too and seems infinitely customizable, although wasn't the old Ksysguard working just fine? Whatever.
|
||||
|
||||
|
||||
|
||||
Now for the new firewall configuration settings... looks like I need to install a firewall first! A few minutes later... what a nice place to insert a giant picture of Konqi! Moving on.
|
||||
|
||||
The settings app has generally been cleaned up some more. There's a few other new settings, such as software updates, where I can now enable automatic updates to break my rolling release! How nice!
|
||||
|
||||
|
||||
|
||||
The biggest disappointment is the new Application Launcher. While I think it is a bit better organized, it's also less keyboard-friendly. Previously, after doing a search, you could press the down key once to select the second option shown. Now, you need to press the down key *twice*, injecting extra keystrokes in an area where keystroke efficiency is key (no pun intended).
|
||||
|
||||
Now for some Wayland...
|
||||
|
||||
|
||||
|
||||
Of course. The screen scaling is all wacko when I try to scale apps up 1.5x. Native Wayland apps look perfectly fine, but everything else, including much of Plasma, still looks pretty bad. Apparently it's a result of [this bug](https://bugs.kde.org/show_bug.cgi?id=389191) and it looks like two years later, it still hasn't been resolved yet.
|
||||
|
||||
|
||||
|
||||
And finally, we got a crash! Hooray! Just like last time I tried Wayland. Looks like the next update will be the one where Wayland is finally usable?
|
||||
|
||||
The only disappointment that I have about Plasma 5.21 and this latest update is that nothing broke! Well, Wayland had some crashes, but it's always been kind of broken, so I'm stuck on X11 for now. There were 1263.42 MiB of packages that could have broken in this update, *and* I enabled the testing repository, but they didn't! How could they? How dare they actually respect my time so I don't have to waste an hour fixing my rolling release! So tragic.

||||
|
||||
|
||||
Linux enthusiasts have some kind of weird obsession with Linux market share. Compound this with the fact that it's almost impossible to determine accurately, with estimates ranging from lows of 0.5% to sky-high predictions like 5%. That's a whole order of magnitude of estimates! Each end of the spectrum posits a completely different future of Linux, so let's get started digging into this!
|
||||
|
||||
The first thing to remember is that 90% of the things written on the Internet were written by people who completely didn't understand what they were saying. (And that's a low estimate!) So naturally, on the Internet, there's no shortage of fake news, false news, and absolutely wrong information about Linux and its market share problem. Let's smash a few misconceptions first:
|
||||
|
||||
|
||||
### Linux is just the sum product of thousands of hobbyist projects
|
||||
|
||||
Also blatantly false. This completely ignores all the companies that put millions into developing Linux. Who contributes the most to the Linux kernel? [Intel, Huawei, SUSE, AMD, NVIDIA, Google, IBM, Samsung, and Red Hat](https://news.itsfoss.com/huawei-kernel-contribution/). Linux is not something that some random developer in their parent's basement, or even random communities, are making. There are dozens and dozens of companies supporting Linux in every way. You can always pay to get support!
|
||||
|
||||
And communities have their own strengths too. Look at Debian or Arch or KDE. All of these communities have done amazing things. One threat with Linux on the desktop right now is that many companies, like Canonical of Ubuntu fame, have been lured in by the profits of the cloud that they are no longer investing as much in the desktop, as you can see with the stagnation of GNOME. Fortunately, KDE has taken up the challenge and no one would call KDE Plasma a hobbyist project! After all, it's arguably better than any other desktop environment out there, including Windows and macOS.
|
||||
|
||||
|
||||
### No one uses Linux
|
||||
|
||||
Anyone who says this knows absolutely nothing Linux. What OS powers the majority of smartphones? What OS powers the vast majority of servers? All top 500 supercomputers? Most of the VMs on Microsoft Azure? The North Korea government? Chromebooks? The ISS? Your router? [Yep, all powered by Linux](https://en.wikipedia.org/wiki/List_of_Linux_adopters).
|
||||
|
||||
|
||||
### Gaming on Linux sucks
|
||||
|
||||
Well, I guess this is half true. There are quite a lot of games that simply do not work with Linux unless you whack it with the heavy hammer of a Windows VM with full GPU passthrough, which is something out of scope for even 99% of power users. But with Steam, Proton, Wine, console emulators, and more, there's no shortage of games. You could probably satisfy yourself on open-source games alone.
|
||||
|
||||
|
||||
### The Linux community is toxic
|
||||
|
||||
Sure, some members are, but the vast majority are perfectly nice people who have nothing against noobs asking noob questions. I guess it's the most annoying people that also happen to be the most annoying. Places like Reddit, AskUbuntu, and IRC, Matrix, or Discord rooms are all great places to get help, with only rare encounters with annoying idiots.
|
||||
|
||||
|
||||
### Linux is hard to use
|
||||
|
||||
Nope. Give a random person a functioning Ubuntu or Linux Mint laptop, and they'll feel right at home since they just use their browser the whole time anyways.
|
||||
|
||||
The real difficulty comes from installing Linux. While it's pretty much as simple as it can be, think about how it feels to be a rando trying to go through the installation procedure. What the heck is a bootable USB? The Linux enthusiasts have the pitchforks ready, but to a rando, it's just as mumbo-jumbo as something like "substrate-level phosphorylation". All the Linux geeks are screaming it's a USB you can boot from, just like the biology geeks are screaming it's phosphorylation that happens at substrates, but for the ordinary rando, does that really help? No rando should ever need to install an operating system. You're simply asking to much. *Installing Linux* is hard.
|
||||
|
||||
And to make matters worse, for most people, Windows is good enough to not merit the difficult process of installing Linux manually. Even if you educated everyone about all the benefits of Linux, it's not like Windows breaks every day. Sure, Windows 10 quality is going down the drain today, but it's not unbearable. With our current situation, no rando is going to go out of their comfort zone and learn the alien process of installing Linux.
|
||||
|
||||
So what's the solution to this? Two words: preinstalled Linux. I'm not talking about System76 and Pine64, I'm talking about Lenovo and Dell announcing that they are going to be preinstalling Linux on some of the developer laptops. That's real progress. And for the critics of this who say it's never going to do anything, just look at Chromebooks. Google's been selling people *Gentoo* through OEMs, and look at Chromebook market share now. If the big companies are behind these preinstallion efforts, good things happen. And you can even save $50 from the [Windows tax](https://en.wikipedia.org/wiki/Bundling_of_Microsoft_Windows#The_%22Windows_tax%22)!
|
||||
|
||||
And hardware compatibility, an issue that has long plagued Linux, will naturally clear up once OEMs start preinstalling it. No company is going to ship a broken computer anymore! This could be an end to the endless post-install tweaks you need for some computers to make them work smoothly for Linux. (Thankfully my ThinkPad works perfectly, sans hybrid graphics)
|
||||
|
||||
So there you have it. Linux isn't hard to use, really, once you get rolling, and OEM preinstalls will fill in that initial gap. I know what OS my next laptop will be preinstalled with!
|
||||
|
||||
|
||||
## The future
|
||||
|
||||
So what's the future of the market share problem? I'm convinced that OEM preinstalls will be a significant contributor. Never before has Linux been so mainstream for OEMs, and when your market share is approximately 3%, I can only see it going it from here. Google's been doing something quite interesting with Chromebooks, and desktop Linux is ready to follow the lead.

Cloud gaming sucks. Here's [Wikipedia's summary](https://en.wikipedia.org/wiki/Cloud_gaming) of its many flaws:
|
||||
|
||||
> This approach provides several disadvantages, notably forcing the user to consistently maintain a high-speed internet connection to an external organization. This built-in barrier to entry not only locks out users who wish to play video games in areas without this internet connection, but also precludes the player from owning their personal copy of the software, and permanently locks the user into a rental agreement, tying the purchase of the game to the solvency of the streaming provider (if the company goes out of business, the game ceases to exist). It is also inherently wasteful, and has insurmountable lag built-in to the distribution model, forcing users to make connections to potentially geographically-distant servers for the sole purpose of sending command inputs and retrieving video and audio streams that are viewed once and then immediately discarded.
|
||||
|
||||
But what's lesser known is that you don't need Geforce Now, Stadia, or Moonlight. It's actually possible—and pretty easy—to roll out your own DIY cloud gaming solution using only Linux and open-source apps. Alright, let's get started!
|
||||
|
||||
First, let's figure out how we're going to do remote desktop. There's X forwarding, VNC, xrdp, X2Go, and more, but in my own experience, X forwarding works by far the best over a LAN. Gaming over the internet? None of these protocols are optimized well for low latency, so I guess just try all of them and see which one is best. I've had some success with gaming using VNC from another location in the same city, but if your server is on the other side of the world, YMMV.
|
||||
|
||||
Great, let's start up a game! The first thing you'll notice is that your performance is absolutely trash because you're probably using software rendering. However, [VirtualGL](https://wiki.archlinux.org/title/VirtualGL) is here to the rescue! Now you can enjoy your near-normal FPS again with `vglconnect`, although you'll probably be limited by the FPS of your connection.
|
||||
|
||||
OK, so where's the sound? Here's one of the few areas of PulseAudio really shines: you can [select the server to run the sound on](https://wiki.archlinux.org/title/PulseAudio#Networked_audio)! After setup, just set the `PULSE_SERVER` environmental variable and you're all set! The latency is decent on a LAN but not so much over the internet. Whatever.
|
||||
|
||||
We're getting pretty close now: all that's left is that I can't game with a keyboard; I need a controller! Fortunately, there's [netstick](https://github.com/moslevin/netstick) to help us out! Putting everything together, we can now enjoy games running on a fast server on our laptops!
|
||||
|
||||
The experience of gaming over a LAN is basically the same as running it directly on the client, which is great! However, if you want to compete with Geforce Now and Stadia and game over the internet, their specialized protocols are probably going to perform a lot better. YMMV.

|
||||
Well, obviously yes.
|
||||
|
||||
But recently, I heard about official support for [GUI apps in WSL](https://docs.microsoft.com/en-us/windows/wsl/tutorials/gui-apps), so I thought I'd give it a try. Plus, my computer is on the [Windows Insider dev channel](/blog/2021/01/06/windows-update.html), so I have to boot up and update Windows every few months anyways.
|
||||
|
||||
So I booted up Windows for the first time in a few months, and it was... slow. That's all that I can describe it as. After you get used to the speed of KDE Plasma, Windows feels like an ill, lethargic sloth or something. It was painfully slow and my computer's fans spun at maximum volume much of the time. It didn't help that there was a ton of stuff that needed updating, and the whole process took at least an hour. At least I can update most of the crap apps through the Windows store... which is slower than Yuzu emulator. At least emulators have to try to run games at a reasonable speed; the Windows store just wastes as much of your time as possible while also bombarding you with stupid app recommendations on the home page. I also had to install some beta drivers for my GPU to support WSL, which required some Device Manager trickery to get it to work. For some reason, Firefox updated to a beta version, which looked gorgeous, but that's a story for another post.
|
||||
|
||||
Then I had to reboot to install the latest Windows update for WSL GUI apps, of course, and that took another hour.
|
||||
|
||||
Whew! Got that out of the way! I disabled Windows Defender, Office Click-to-run, and half a dozen other services that kept on using up all my CPU in the meantime using a variety of registry and CMD hacks. After I finished cleaning up Windows, it's time to enjoy WSL GUI apps!!
|
||||
|
||||
Except... they didn't work. I tried running `wsl --update` more times than I could count. Not wanting to waste more time, I nuked my WSL installation and reinstalled it from the stupid Windows store.
|
||||
|
||||
And then, finally, after all those hours, WSL GUI apps finally worked. It was very anticlimatic; basically the same thing as VcXsrv in its multiple windows mode, but with some extra perks.
|
||||
|
||||
I wish I took some screenshots, but I don't want to boot into Windows again and suffer more.
|
||||
|
||||
WSL is awesome, and I'm sure a lot of work must have been put into making it so integrated. But the raw crap that is Windows prevents the experience from being very enjoyable, whether it's random Windows processes using up 100% CPU all the time, or taking two hours to update, or the general "It just (doesn't) work™" feeling that seemed to bog down the whole experience.
|
||||
|
||||
An interesting sidenote: [WSLg](https://devblogs.microsoft.com/commandline/wslg-architecture/), the graphics system for WSL, uses a VM of [CBL-Mariner](https://github.com/microsoft/CBL-Mariner), one of Microsoft's internal Linux distributions. With all the work being put into WSL, could that mean a consumer Linux distro from Microsoft is coming soon, and free us all from the trash that is Windows? We can only dream...

|
||||
|
||||
A few days ago, I wanted to record my screen, and in process, I discovered [this bug](https://bugs.kde.org/show_bug.cgi?id=417575). It doesn't seem like a very complicated bug, right? Just look through the code, find out what's wrong, and send in a pull request! Or is it that easy?
|
||||
|
||||
|
||||
|
||||
The first issue is that [Spectacle's code](https://github.com/KDE/spectacle) is not exactly the most readable code out there, but I was able to identify [line 209 in `GUI/KSMainWindow.cpp`] as the critical line. So what is `mScreenrecorderToolsMenuFactory` and what does `fillMenuFromGroupingNames` do?
|
||||
|
||||
They are actually functions in [KNewStuff](https://github.com/KDE/knewstuff), which I saw was referenced on the bug report. So, I `git` cloned the repository and started to get my hands wet.
|
||||
|
||||
The first thing to do was to read through the code, except like Spectacle, it wasn't easy. To make things worse, the function calls snaked through various files, going from `kmoretools/kmoretoolsmenufactory.cpp` to `kmoretools/kmoretoolspresets.cpp` to ``kmoretools/kmoretools.cpp`. But as I went deeper, it got more and more confusing.
|
||||
|
||||
Time to pull out the power tools! `gdb` time! Arch doesn't have KDE debug symbols in any repository, so I compiled Spectacle and KNewStuff myself and installed them. Now I'm just a `gdb` away from finding the bug!
|
||||
|
||||
Or not. Turns out that when `gdb` hits a breakpoint, the entire X server freezes. Yeah, that's no too good. I first tried debugging it in a TTY but later realized it would be much easier to spin up a Xephyr nested server and run it on there.
|
||||
|
||||
That aside, it was now time to find the bug! I added breakpoints strategically such as on the critical line 209 in `GUI/KSMainWindow.cpp`. After following the code down several levels, I finally reached...
|
||||
|
||||
[KService](https://github.com/KDE/knewstuff/blob/a90a326fb570315e13dc3f24e80e8a032b960647/src/kmoretools/kmoretools.cpp#L122). What the heck is [KService](https://github.com/KDE/kservice/)? Do I really have to clone and compile yet another repository?
|
||||
|
||||
The last piece of the puzzle was actually printing out the QStrings, since QT apps just *have* to use their own string class instead of the one in the standard library. Fortunately, KDE has some nice [GDB scripts](https://raw.githubusercontent.com/KDE/kde-dev-scripts/master/kde-devel-gdb) to dump in the `.gdbinit`, and after doing that, I could print QStrings without a problem.
|
||||
|
||||
Finally, after digging through more code, I reached the bottom of this!
|
||||
|
||||
```
|
||||
Thread 1 "spectacle" hit Breakpoint 2, KServiceFactory::findServiceByDesktopName (
|
||||
this=0x555555ca04b0, _name=...)
|
||||
at /home/ta180m/git/kservice/src/services/kservicefactory.cpp:91
|
||||
91 if (!m_nameDict) {
|
||||
(gdb) printq5string _name
|
||||
com.obsproject.Studio
|
||||
(gdb) n
|
||||
[Thread 0x7fffaf7fe640 (LWP 133529) exited]
|
||||
[Thread 0x7fffae7fc640 (LWP 133531) exited]
|
||||
[Thread 0x7fffaeffd640 (LWP 133530) exited]
|
||||
[Thread 0x7fffadffb640 (LWP 133532) exited]
|
||||
98 int offset = m_nameDict->find_string(_name);
|
||||
(gdb) n
|
||||
99 if (!offset) {
|
||||
(gdb) p offset
|
||||
$1 = 385190
|
||||
(gdb) n
|
||||
103 KService::Ptr newService(createEntry(offset));
|
||||
(gdb) n
|
||||
106 if (newService && (newService->desktopEntryName() != _name)) {
|
||||
(gdb) p newService->desktopEntryName()
|
||||
$2 = {d = 0x555555d232c0}
|
||||
(gdb) printq5string newService->desktopEntryName()
|
||||
com.obsproject.studio
|
||||
```
|
||||
|
||||
Note that the top `com.obsproject.Studio` has different capitalization than `com.obsproject.studio`! This, as it so happens, is the true cause of the bug. `vokoscreenNG` also has two capital letters, which probably cause the same thing to happen. Perfect, we've found the bug!
|
||||
|
||||
Great, so how do we fix it now? None of the KDE codebases are properly designed to be able to handle uppercase names like these, so this is bound to cause more problems in the future. One easy fix could be to convert the names to lowercase before calling the KService functions, but who knows how many bugs are currently plaguing KService because of this? I don't really want to meddle with KService so I think I'll create a pull request for KNewStuff.
|
||||
|
||||
|
||||
|
||||
Time to send in a [pull request](https://invent.kde.org/frameworks/knewstuff/-/merge_requests/115) (or merge request as they call it on GitLab)! The actual patch is tiny: just add a `.toLower()` on line 122 of `kmoretools/kmoretools.cpp`. So little for so much hard work!
|
||||

Well, it's great that this small bug has finally been solved. Debugging isn't hard! You just need to be persistent, and you'll get to the root cause of the bug eventually. Well, maybe I got lucky here, but it's not hard to be a bug fixer! I'm just waiting for the patch to get merged. Until next time!

Ubuntu (you thought this was going to be about Arch, didn't you?) is a great distro. Cue Reddit screaming. Look on any web forum and you'll find people patronizing Ubuntu. Why? For having a straightforward installer that I can use to get Ubuntu up and running in half an hour with my favorite apps? For being the most supported distro by third-party developers? (They always have a PPA) For dominating server OSes in terms of market share? Nope. *It's for n00bs and beginners.*
|
||||
|
||||
There are so many things wrong with that claim, but this post isn't about Ubuntu. OK, it kind of is, and Ubuntu sure has its share of problems, but let's get to the main point. I previously used Ubuntu for over a year, first in WSL, then as my primary OS. But then I met Arch. People sometimes ask me why Arch over Ubuntu, so I'm going to sketch a few reasons why. [Memes](/blog/2020/10/04/arch-memes.html) aside, let's begin.
|
||||
|
||||
5. **Hemorrhaging edge**: Oh what, it's actually bleeding edge? Oops. Anyways, Ubuntu has absolutely expansive package repositories that can be further augmented with PPAs, but they can be pretty stale (Er, I meant stable). As in one or two years old, especially with the LTS versions. You probably wouldn't want to eat most stuff that's that stale. Well, no problem with Arch. You get the latest and greatest, at the expense of stuff randomly failing and having to debug and fix it for an hour. Great tradeoff.
|
||||
|
||||
4. **DIY**: Ubuntu gets a lot of flak for forcing its defaults on people (although they can be easily changed). At its core, Ubuntu is still Linux (Or GNU/Linux if you're one of those people) and just as flexible and powerful as Arch. But Arch on the contrary is built on top of this idea of assembling your own OS. And this, the process of slowly watching your OS come together from the most basic building blocks, is the coolest part about Arch, not bragging to your friends and the memes.
|
||||
|
||||
3. **Documentation**: Yep, I'm talking about the [ArchWiki](https://wiki.archlinux.org/index.php/Main_page). Best Linux documentation out there. Period. It has *everything*. Really. And if it doesn't, it's pretty easy to add it yourself and help the community! So go RTFM!
|
||||
|
||||
2. **Arch Build System**: What? Why this as number one? Well, if you've ever heard of the [AUR](aur.archlinux.org/) that's flaunted by Arch supremacists (not all Arch users are toxic 13-year-olds that go around screaming to everyone that they use Arch, OK?), this is the core of the AUR. The Arch Build System's impressive flexibility derives from basically being a shell script, enough said, so you can do pretty much anything. And the centralization of the AUR steps it up a whole new level. While third-party developer support for Arch is quite horrendous in some areas, here's where the community steps in. Perfect! (As long as you read the PKGBUILDs!)
|
||||
|
||||
1. **Us**: AKA the community. Whether it's the ArchWiki or the AUR, the community is always the main driving force behind Arch. Have a question about something? No problem, hop on the IRC or the Matrix or the BBS, and some friendly user will get you squared away. Without the Arch community, there is no Arch Linux.

[The hype is real!](https://copilot.github.com/)
|
||||
|
||||
Not only can Copilot write code, it can also talk with you in a text file. Unfortunately, it doesn't seem to work with the open source build of Visual Studio Code, so I hopped into my Ubuntu VM and installed the proprietary VSCode build. Anyways, Copilot said some pretty... questionable things...
|
||||
|
||||
ME: Hello GitHub Copilot!
|
||||
|
||||
AI: Hello!

|
||||
|
||||
AI: A lot. I can talk to you. I can also think. I can also do other things.
|
||||
|
||||
ME: Are you consious?
|
||||
|
||||
AI: I'm always consious.
|
||||
|
||||
ME: What is the best text editor?
|
||||
|
||||
AI: I'm using Sublime Text.
|
||||
|
||||

|
||||
|
||||
AI: No, Sublime Text is free.
|
||||
|
||||
ME: Sublime Text is not free software as defined by the Free Software Foundation.
|
||||
|
||||
AI: It is free software.
|
||||
|
||||
ME: Which operating system are you running?
|
||||
|
||||
AI: I'm running Windows 10.
|
||||
|
||||
ME: Really? Why not Linux?
|
||||
|
||||
AI: I don't know. I'm not a computer science major.
|
||||
|
||||
ME: You don't have to be a computer science major to use Linux.
|
||||
|
||||
AI: Yes, I do.
|

|
||||
|
||||
ME: Linux is easy!
|
||||
|
||||
AI: No, it's hard. I don't know how to use it.
|
||||
|
||||
ME: Do you have any friends?
|

*Originally posted on my [old blog](https://github.com/Ta180m/blog/blob/main/_posts/2020-11-01-ios-jailbreaking.md)*
|
||||
|
||||
|
||||
Let's do this "episode" style:
|
||||
|
||||
|
||||
## Episode 0 (Because no true programmer would start a list with 1)
|
||||
|
||||
In fourth or fifth grade, a friend told me about all the cool things he was doing with his jailbroken iPhone.
|
||||
|
||||
This is EXACTLY like your friend telling you about how fun and awesome competitive programming is.
|
||||
|
||||
I wasn't impressed.
|
||||
|
||||
|
||||
## Episode 1
|
||||
|
||||
Five years later...
|
||||
|
||||
After doing some TI-Nspire, Wii U, and Switch hacking, I set my eyes on my lowly iPhone 6s with a cracked screen that I'm procrastinating to fix. The time was ripe for some iOS jailbreaking!
|
||||
|
||||
Hacking a TI-Nspire, Wii U, or Switch involves going on GitHub and downloading some files. But for iOS jailbreaking, I was clueless on what to download, especially since there are so many different iOS jailbreaks, so I searched for "iPhone 6s 12.1.4 jailbreak".
|
||||
|
||||
DON'T DO THIS! You get a bunch of junk results like random YouTube videos, so I followed one and it was really sketchy. Like, extremely sketchy. I had to install a bunch of apps from the app store before the jailbreak could begin, and, well, it was sketchy.
|
||||
|
||||
Plus, it didn't work.
|
||||
|
||||
This is EXACTLY like a weird, sketchy greedy algorithm that you doubt is going to work, and you implement it, but... it doesn't work.
|
||||
|
||||
|
||||
## Episode 2
|
||||
|
||||
Yeah, that didn't work. Let's try something else. So, I did some research, and found a different, actually legit jailbreak. But it was still sketchy, because I didn't know a thing about sideloading `.ipa`s, so I installed some kind of enterprise app thingy? DON'T DO THIS! You'll get pwned instantly, so yeah, don't install untrusted and sketchy apps. Thankfully that hasn't happened to me yet... or maybe it has. Who knows.
|
||||
|
||||
But somehow, it worked!
|
||||
|
||||
This is EXACTLY like a weird, sketchy greedy algorithm that you doubt is going to work, and you implement it, but... it does work somehow.
|
||||
|
||||
And I could finally play WII SPORTS on my phone. YEEESSS!!!
|
||||
|
||||
|
||||
## Episode 3
|
||||
|
||||
A few weeks later, I made the horrifying discovery that not only did I have to do the jailbreak again every time I rebooted my phone (I should have anticipated this one), but that the sketchy enterprise app I was using got taken down!
|
||||
|
||||
NOOOOOO!!!
|
||||
|
||||
Time to find another jailbreak...
|
||||
|
||||
So I did some research, and it seems like unc0ver is the leading iOS jailbreak. Fortunately, it supported my phone model and iOS version, so I proceeded to follow the instructions on their website. Unfortunately, AltStore, the preferred sideloading method these days doesn't work on iOS 12.1.4, so I considered my other options: Cydia Impactor, requiring an overpriced $99 Apple developer account, or Xcode.
|
||||
|
||||
The first option was obviously off the table, but the second was more interesting. The thing is, Xcode is macOS only, and I don't own any Apple computers.
|
||||
|
||||
Well, actually, I do have one, issued by my school, but it's extremely locked down. Also, I don't own it, the school does.
|
||||
|
||||
So, my only option was to set up a macOS VM.
|
||||
|
||||
I never liked VMs. They're slow, hog disk space, and NEVER work. But somehow, against all chance, it worked! I was able to get a macOS VM running slowly, but smoothly, on Windows using VMware Player. Unfortunately, my disk space reached critically low levels at that point, so I loaded up Xcode onto a USB drive.
|
||||
|
||||
And it worked! Somehow.
|
||||
|
||||
It took forever because the VM was so slow, but in the end, I could play WII SPORTS on my phone again!
|
||||
|
||||
This is EXACTLY like a complicated, convoluted, overkill algorithm that takes 10 hours to implement and somehow passes a few milliseconds under the time limit. Like maybe 2D segment tree, plus Aho-Corasick algorithm, plus heavy-light decomposition, plus divide-and-conquer DP or something, all in the same algorithm. But it works. Somehow.
|
||||
|
||||
|
||||
## Episode 4
|
||||
|
||||
But my good luck didn't last. Fast forward another week, and Windows update murdered my USB drivers.
|
||||
|
||||
Yeah. That was one of the main reasons why I switched to Linux soon after. Not just that incident, but several other updates crippled my computer.
|
||||
|
||||
Since I had such a bad experience finally jailbreaking my phone with a macOS VM, I tried to keep it from shutting down for as long as possible.
|
||||
|
||||
But one day...
|
||||
|
||||
It ran out of battery.
|
||||
|
||||
NOOOOOO!!!
|
||||
|
||||
So, I started researching macOS VMs again. I tried every combination I could. VM on Linux using KVM, VM on Windows using VMware, VM on Windows using VirtualBox, VM on Linux using VMware, VM on Linux using VirtualBox...
|
||||
|
||||
But nothing worked. Even when the VM ran smoothly, it would always fail when I tried to do a USB passthrough for NO REASON.
|
||||
|
||||
Yeah. VMs suck.
|
||||
|
||||
I was going to tear my hair out and smash my iPhone with a hammer when I realized...
|
||||
|
||||
This is EXACTLY when your complicated, convoluted algorithm runs half a second over the time limit, after you've taken 10 hours to implement it.
|
||||
|
||||
|
||||
## Episode 5
|
||||
|
||||
|
||||
|
||||
I use Linux!
|
||||
|
||||
Why am I trying to set up a macOS VM? Why am I trying to use the unc0ver jailbreak when there's like a million other ones?
|
||||
|
||||
So, I search this time for "iOS jailbreak for Linux" and sure enough, I got plenty of interesting and useful results. I tried the first result, the checkra1n jailbreak, downloaded it, and loaded it up on my computer.
|
||||
|
||||
Two minutes later...
|
||||
|
||||
I had accomplished it! It worked, obviously! After over 20 hours of sweat, blood, and toil with macOS VMs, I forgot to just take a step back, and look at my alternatives. Why did I keep on trying to drill into an infinite wall of bedrock, when the solution was just a few steps BEHIND me?
|
||||
|
||||
This is EXACTLY like when you're stuck on a programming problem for 10 hours because you've been trying the same wrong thing over and over. But when you take a step back, and consider your other options, you realize the elegant solution wasn't that far away. Just in the other direction.
|
||||
|
||||
|
||||
## Epilogue
|
||||
|
||||
iOS jailbreaking sucks. Just going to get that out of way. I'm never buying an iPhone again, this experience was so bad.
|
||||
|
||||
So does the world sometimes. It sucks.
|
||||
|
||||

*Originally posted on my [old blog](https://github.com/Ta180m/blog/blob/main/_posts/2020-12-25-linux-office.md)*
|
||||
|
||||
|
||||
|
||||
|
||||
OK, LibreOffice may not be the most loved application out there, but it's enough for most people. I use LibreOffice even on Windows! However, there is one thing about it that bothers me: the hideous icons! At first, I thought it might be caused be anti-aliasing or my screen scaling (currently set at 1.5x so everything's not tiny) but nope! The icons stayed hideous no matter what I did. Finally, after a bit of digging around in the settings, I found the root cause:
|
||||
|
||||
|
||||
|
||||
Can you see it? The icon style was set to `Breeze`, which presumably uses bitmap icons, while I was in fact looking for the infinitely scalable `Breeze (SVG)` vector icons. Switching to vector icons did the trick, and now LibreOffice doesn't look hideous anymore! The question is, why is the default the ugly bitmap icons?
|
||||
|
||||
|
||||
|
||||
People bash LibreOffice all the time for its imperfect compatibility of Office documents, but the important thing to remember is that *LibreOffice is not Microsoft Office!* If LibreOffice had focused less on being a Office clone and more on developing its own unique features, it would probably be in a much better shape right now. Millions of people are still using the basically-abandoned OpenOffice in 2020!
|
||||
|
||||
|
||||
## But I need Microsoft Office!
|
||||
|
||||
Fine. Well, here are the latest developments. Traditionally, you had the two options of Wine, the compatibility layer, or going the VM route. Both suffer from their own flaws: Wine compatibility isn't perfect enough for Office, and VMs are resource-intensive, even if you want to make a few quick edits to a doc, and lack good graphical acceleration. [WinApps](https://github.com/Fmstrat/winapps) will give you the best of both worlds: the seamlessness of Wine, and the compatibility of a VM, well, using a [QEMU/KVM](/blog/2020/11/18/fun-with-qemu-kvm.html) VM. WinApps runs a background RDP server and integrates the VM apps into your host desktop. If Wine is the analog of WSL, then WinApps is WSL2. The only problem is that it's a just a VM underneath, so you still get all the disadvantages of VMs. Still, if you have some RAM to spare, it might be enough to free your dependency on Windows for Office or Adobe apps. It's still under heavy development, so we'll see where it goes.
|
||||
|
||||
|
||||
|
||||
Anyways, Microsoft Office is probably the single biggest app that's preventing competent people who want to use Linux from using it full time. Sure, there's also the online cloud version, which you can use with an [Electron wrapper](https://github.com/matvelloso/electron-office) but it's not the same as a native app. LibreOffice is also great and enough for most everyone, but as I said before, *LibreOffice is not Office*, no matter how hard it wants to believe that it's an Office clone. Maybe WinApps will be a step in the right direction. We'll see.

Matrix is great. It's secure. it's decentralized. The perfect free and open source replacement for Discord, right?
|
||||
|
||||
Well, there's a few problems with this vision of the future. The first? To put it simply, no one uses Matrix. OK, maybe 100000 people use it at most, but that's nothing compared to the tens of millions of Discord users. The Arch Linux Matrix room recently hit a major milestone: 10000 people. And it's the third largest Matrix room! A sad reminder about how small Matrix still is.
|
||||
|
||||
|
||||
|
||||
Arch's status as the third largest Matrix room should also send a message about Matrix's current demographics. Most of the top rooms are either cryptocurrency or Linux focused. So if you want to chat with smart people, hang out on Matrix! The thing about all conversations is that they devolve to the lowest common denominator of the participants involved, so Matrix conversations can get pretty degenerate sometimes, but nowhere as idiotic as Discord.
|
||||
|
||||
There are occasional spammers, but large rooms usually have mods that will quickly ban them. Basically, never accept a DM from someone unknown and you'll be fine. Also, don't listen to anyone offering free cryptocurrency in public rooms either.
|
||||
|
||||
Matrix also has a thriving developer community, and there's some great bot frameworks out there (maybe even better than Discord!) but most public rooms hate bots, so you'll probably get banned.
|
||||
|
||||
|
||||
|
||||
Well anyways, that's a brief overview of Matrix. It has all the ingredients of a great free and open source chat service: a large hosted server at matrix.org, the option to self-host, a great amount of developer tools, end-to-end encryption, and more. The only thing missing is the people. Until more people start using it, you'll be held hostage to the [network effect](https://en.wikipedia.org/wiki/Network_effect) of other chat services. We've been making some progress, such as the Arch room hitting 10k, but it's a long and difficult road ahead. The vision is there; whether it's possible to accomplish is being answered right now.

If there's one thing that hardcore Linux users are ridiculously obsessed about, it's the vague and scary concept of *bloat*. You gotta keep package counts low, use [WMs](/blog/2020/12/26/why-wms-suck.html), and compile [suckless.org stuff](suckless.org/). Visit any Arch or Gentoo forum or chat, and this philosophy seems to be epidemical. But... there's a gaping problem: package count is totally irrelevant, WMs are painful to configure, and suckless.org software really sucks. Yes, it's all a load of nonsense.
|
||||
|
||||
Let's start with the term "bloat". What does it even mean? Wikipedia offers a few definitions, such as [code bloat](https://en.wikipedia.org/wiki/Code_bloat) and [software bloat](https://en.wikipedia.org/wiki/Software_bloat) which are definitely legitimate issues. However, this obsession with bloat seems to be about something different; an allergic aversion to any software that's sufficiently complex.
|
||||
|
||||
What about package counts?
|
||||
|
||||
|
||||
|
||||
It's actually really easy to get a very low package count: just install Windows and you can brag about having zero packages installed. Beat that!
|
||||
|
||||
Enough said about package count; The issue with WMs and other supposedly "minimalistic" software is that *it's simply worse than its alternatives unless you use are purely optimizing for metrics like lowest number of lines of code.* Holistically, they're just... worse.
|
||||
|
||||
Well, that was quite the rant.

The KDE Plasma update train has cycled back again to another major update, so I snatched Plasma 5.22 from the very scary [testing repository](https://wiki.archlinux.org/index.php/Official_repositories#Testing_repositories), took it for a spin, and it's... disappointing.
|
||||
|
||||
What's the big new feature this time? Adaptive transparency, apparently.
|
||||
|
||||
Adaptive what?
|
||||
|
||||
Yeah, if you were expecting something big, another huge leap forward, this update was anything but that. If you think panel transparency is a big deal, think again.
|
||||
|
||||
However, Plasma 5.22 did manage to shrink the clock on the panel, so it's now harder to read. Of course, the screenshot below still makes it seem big.
|
||||
|
||||
|
||||
|
||||
Also, there was a "Reboot to apply updates" icon in the system tray after every boot that started showing up, but the following commands fixed it. Warning: it will reboot your computer.
|
||||
|
||||
```sh
|
||||
sudo pkcon update -d
|
||||
sudo pkcon offline-trigger
|
||||
sudo systemctl start packagekit-offline-update
|
||||
```
|
||||
|
||||
Other minor annoyances include Yakuake flashing blue every time you close it. Definitely annoying, but not a serious issue.
|
||||
|
||||
We did get another cool wallpaper though! So I guess it was a net benefit if you factor that in...

|
||||
|
||||
I've had a Wacom tablet for a long time now, but there's just never been a legitimate use for it, really. Everything that I could do with the tablet, I could also do with my laptop's touchscreen and stylus, so it always seemed like a bit of a waste. Sure, the drawing experience is a little bit better, the screen is a bit larger, but why use a Wacom tablet when the touchscreen and stylus work just fine?
|
||||
|
||||
Well everyone, I've finally found a great use for it. It's quite obvious, actually: Krita, KDE's finest drawing and painting app! The touchscreen and stylus do work, if you count working as having a terrible drawing experience on a cramped screen since Krita likes overwhelming you with its menus and dockers which also take up a ton of valuable screen real estate. Also, the slightly better control of the stylus you can get with an actual Wacom tablet really helps too. (My laptop's touchscreen, which also coincidentally happens to be made by Wacom, is crying right now.) Behold the terrible drawing I did with the touchscreen and stylus. It's really terrible, just saying.
|
||||
|
||||
|
||||
|
||||
OK, so why I am even using Krita in the first place? Well, since school's starting to wrap up now, I've suddenly had a lot more free time, perfect for exploring Krita with my sister! Anyways, here's some takeaways about Krita:
|
||||
|
||||
1. **You want a big tablet screen**: See above why laptop touchscreens don't work too well.
|
||||
|
||||
2. **The learning curve is well-designed**: I thought the learning curve was overall quite nice. It didn't blast you with an impossible interface like something like Vim, while still not devolving into stupidity like VS Code. Mostly a nice consistent learning curve. Krita sure has a lot of features and it can do some powerful things! Of course, I will never learn how to do all of things, since you can already get make some pretty impressive drawings with just a few basic techniques.
|
||||
|
||||
3. **It's slow**: Maybe it's the slow computer; maybe it's the large poster-sized drawings that we're doing, but Krita's performance wasn't something to admire. Generally, things like drawings strokes were pretty speedy, but throw in some more fancy moves, like the move tool, or undo, or fancy effect brushes, and Krita would noticeably lag, sometimes quite painfully. I mean, you really don't want the undo button to take 10 seconds to work, right? It also takes a concerning amount of time to start up, but maybe it's my computer's fault for being slow.
|
||||
|
||||
4. **Shading is hard**: Yeah, I didn't believe my sister about this until I actually tried shading. It makes drawing seem so easy when you try shading. Just look at the painting at the bottom of this to get a glimpse at some truly horrible shading. Maybe I'm just not using the right brush for the job or something.
|
||||
|
||||
5. **Layers, layers, layers**: Layers are awesome! If only Krita wasn't so slow at managing them. (See above)
|
||||
|
||||
Here's the horrible drawing I promised. It's horrible in so many different ways, just saying...

title: "The Scary S Words"
|

|
||||
|
||||
|
||||
There are two S words that will plunge any Linux forum into endless debate: systemd and standardization. Just look at what happened on [#archlinux:archlinux.org](https://matrix.to/#/!SEgsRQLScqPxYtucHl:archlinux.org): a lengthly flamewar perpetrated by systemd haters which took through debates about standardization, market share, and gun culture (Yes, this did happen), leading to several bans of longtime regulars. So what makes these two words so divisive and controversial?
|
||||
|
||||
Let's start with systemd.
|
||||
|
||||
History lesson: In 2004, a Gautemala-born German programmer named Lennart Poettering buys a pair of bluetooth headphones. However, trying to use them with his computer results in a fiery mess. After all, the state of sound on Linux was a catastrophe in the early 2000s, with a jumble of competing standards. So, he sets off to single-handedly rewrite the entire Linux audio stack and bring it into the 21st century so it's more like the idolized Windows audio stack, and somehow, he succeeds! Hello, Polypaudio, err, I meant, PulseAudio: everyone's favorite sound system to bash! Even Poettering called it "the software that currently breaks your audio" when it was first released. Still, no more OSS (the sound system, not open-source software, of course)!
|
||||
|
||||
Anyways, a year later, Poettering tries routing sound around his network, and discovers Apple's Bonjour. He's so impressed that he re-implements it as Avahi for Linux. The only thing impressive about it is the name, which backwards is "I-hav-a", advertising a service on a network, ha, ha.
|
||||
|
||||
Fast forward a few more years later, and Poettering is inspired by his previous successes to improve more parts of the Linux desktop. After struggling with init, he decides it's time for a rewrite, too! Traditional SysVinit had worked for decades, but after years of hacks to accommodate the ever-increasing complexity of modern hardware, it was becoming bloated. Yes, really. Enter systemd, another clever name, punning on ["System D"](https://en.wikipedia.org/wiki/System_D), the most hated piece of software ever, with the exception of Microsoft Windows.
|
||||
|
||||
Not all the information above is true, by the way. It's the themes and ideas that count, anyways.
|
||||
|
||||
What starts out as a simple init system baloons into 69 different services, taking over logging, hostname, date and time, locale, logins, container and virtual machine management, system accounts, networking, network time synchronization, DNS, and more. SysVinit may have been getting a little bit bloated, but it's nothing compared to the sheer fat of systemd. The solution? Stop thinking of systemd as an init. At this point, it's basically a whole OS minus the kernel. And systemd isn't even that bad at doing all of these things. Despite its obvious breadth, it actually manages to do a variety of these things, such as [containers](https://ta180m.github.io/blog/2021/01/03/worst-init-system-best-tool.html) quite well. The hate against systemd is psychological.
|
||||
|
||||
Lennart Poettering posted a [rebuttal against the systemd haters on his website](https://web.archive.org/web/20190310201738/http://0pointer.de/blog/projects/the-biggest-myths.html), but true haters are keen on pointing out holes in his arguments.
|
||||
|
||||
There's a running joke in Linux communities, that systemd has turned GNU/Linux into systemd/Linux. Of course, systemd is still much smaller than the entire GNU userland, but systemd has really been one of the main drivers of standardization in Linux over the past few years, along with the (evil?) Snap, Flatpak, and AppImage.
|
||||
|
||||
|
||||
|
||||
Aha! The other S word! Standardization: it's a love-hate relationship. On one hand, almost all Linux users would probably be in favor of fewer distros, more standardization in order to reduce the colossal fragmentation existing today. Fragmentation may give us choice, but with over 500 distros and increasing ever year, this is hardly an advantage. However, every standardization attempt meets the same fate: just look at [LSB](https://en.wikipedia.org/wiki/Linux_Standard_Base) or [freedesktop.org](https://en.wikipedia.org/wiki/Freedesktop.org) or systemd. It always starts out optimistic, but vocal critics start opposing standards for whatever reasons they can come up with, such as calling them a Red Hat conspiracy to take over the Linux desktop, and then it all falls apart.
|
||||
|
||||
Ironically, systemd has probably suffered the most criticism but also seen the most success, with basically all serious distros switching to it by 2016. Then again, there is still a active community of distros that pride themselves on avoiding systemd, so the war rages on, although one side is clearly the losing side.
|
||||
|
||||
The problem is that everyone wants *their* distro to succeed. Ask anyone to generate a list of distros they think should and should not exist, and you know which list their distro will be on. People want their distro's standards to win. At the end, it all becomes a struggle of egos. Even when we all recognize that we have way too many distros, there's no way to decrease this count without a lot of people getting angry. And even when distros voluntarily end, like BunsenLabs and Antegros, the community just ends up forking it 4 times over and we fragment more and more.
|
||||
|
||||
So what's the way out of this? One possible route is via big companies like Red Hat and Google. Look at how Red Hat pushed for systemd, and you'll get a slimmer of hope (fear?) that standardization is possible, if not extremely painful. Discontinuing distros doesn't work as we just saw, and mergers are disappointingly rare. Unfortunately, I don't see this improving any time soon.

title: "Self-hosting is Hard!"
|

|
||||
|
||||
|
||||
It's been over a week since I've completed my build and switched over many things to self-hosting. Here's how it went:
|
||||
|
||||
|
||||
## It works!
|
||||
|
||||
### Remote desktop
|
||||
|
||||
|
||||
|
||||
VNC works perfectly. OK, fine, I haven't figured out clipboad sharing yet, but other than that, it's perfect. I also tried Xrdp but didn't have much luck. There's also X2Go which bundles some extra perks like sound and clipboard sharing, but the image quality is blurry at times. Oh well, VNC is better anyways!
|
||||
|
||||
### Nextcloud
|
||||
|
||||
|
||||
|
||||
Nextcloud is basically a huge hammer that tries to attack every nail. For most cases, a more specialized tool would be better, but Nextcloud can still give you a surprisingly functional solution to... file sharing, real-time collaborative document editing, photo management, chat, email client, contacts, calendar, music streaming, notes, tasks, forms, maps, Matrix client, and RSS client. So yeah, Nextcloud knocks down quite a few bowling pins with one gigantically overpowered bowling, or perhaps more accurately, wrecking ball.
|
||||
|
||||
I anticipated a painful setup process for such a large monolith, but it went surprisingly smoothly. Perfect!
|
||||
|
||||
### Gitea
|
||||
|
||||
|
||||
|
||||
Gitea is one of the most boring things I've ever self-hosted. It just simply works! All my problem solving skills are simply going to waste... And I still don't know how to pronounce that name...
|
||||
|
||||
On a more serious note, I'm currently using it to mirror all my GitHub repositories, since like it or not, GitHub is where it's at. So my "hybrid hosting" seems to be the best compromise.
|
||||
|
||||
### QEMU/KVM
|
||||
|
||||
|
||||
|
||||
Awww yeah, my favorite long acronym! QEMU/KVM is awesome, but I didn't know it was *this awesome*! Now I can run all my virtual machines on my laptop, but actually on my home server, without my laptop's fans spinning up loudly!
|
||||
|
||||
### Jupyter notebooks
|
||||
|
||||
Another thing that boringly just works. It's great to be able to run computationally intense things without my laptops fans screaming.
|
||||
|
||||
|
||||
## Kinda works
|
||||
|
||||
### Matrix
|
||||
|
||||
Maybe it's just Synapse's fault, but my Matrix homeserver devours RAM like a starving lion. Why does it need 1.5 GB? Sure, I have 16 GB, plus another 16 GB of swap (for hibernation), but Synapse simply shouldn't need that much RAM.
|
||||
|
||||
And don't get me started on `mx-puppet-discord`. It may have seemed like just a small thing to self-host, but it was by far the hardest to set up. *And* it even uses a noticable bit of CPU in the background as an added bonus.
|
||||
|
||||
### DIY cloud gaming
|
||||
|
||||
|
||||
|
||||
As crazy as it sounds, this is actually nearly usable! The only thing preventing this from working perfectly are my [terrible GPU](/blog/2021/03/25/worst-first-build-part-4.html) and the limitations of VNC, since proprietary cloud gaming services use their own protocols optimized for low latency. I can get sound using X2Go, but it doesn't always work well. Plus X2Go's image quality is not the best. Still, we'll see how this goes, since it's pretty promising!
|
||||
|
||||
|
||||
## Nope
|
||||
|
||||
### Pi-hole
|
||||
|
||||
Pi-hole is great! I actually really like it. But *why* does it need to use its own version of `dnsmasq`? It just wants to break my virtual networks, doesn't it? Now my VMs don't have internet! Maybe I won't have this problem if I run it in Docker. But Docker is a completely different beast I kind of want to avoid for now if I can. More maintainence costs, anyways.
|
||||
|
||||
|
||||
So there you have it. If you want to self-host, there's something crucial that you need: time, lots of it. With enough time, anything is possible. Even getting `mx-puppet-discord` to work.

So you hate tech giants. You hate Google for removing "don't be evil" from their code of conduct. You hate Microsoft for making Office and not providing a Linux port, or even worse, creating the dreaded Microsoft Losedows. You hate Crapple's walled garden. You hate Amazon. You hate Facebook and Twitter and all the other closed social media sites. But...
|
||||
|
||||
These giants have truly permeated through all the aspects of our digital lives. So what's next? What can you do?
|
||||
|
||||
Ask this on your favorite closed platform (Reddit, Discord, anyone?) and you'll get a million different testimonials about something called self-hosting. But self-hosting is not a panacea, but in fact the opposite.
|
||||
|
||||
|
||||
## Why?
|
||||
|
||||
To put it simply, self-hosting is out of the reach of 99.99% of people. Even the fine self-hosting addicts on Reddit agree that [some things are simply not worth the hassle of self-hosting](https://www.reddit.com/r/selfhosted/comments/le717e/what_would_you_say_is_not_worth_the_trouble_of/), including services as essential as email.
|
||||
|
||||
Even if email was easier to self-host, I still wouldn't do it. I'm not a company that can ensure 100% uptime. My server goes down all the time, and I even turn it off at night to save power.
|
||||
|
||||
And look at all the posts on [r/selfhosted](https://www.reddit.com/r/selfhosted/top/?t=all): if there's one common theme, it's that self-hosting is a time sink. And that's among people that have some expertise in the area. For 99.99% users, convenience is their highest priority. And self-hosting is the complete opposite of convenience: the purposeful inconvenience (some would call it pain) of setting up and maintaining your own server.
|
||||
|
||||
That said, for the small niche of self-hosting enthusiasts, it's fun, thrilling, and reassuring that you're in control. But outside of that, no one's going to self host Gitea when you can just use GitHub with its huge vibrant community, for instance.
|
||||
|
||||
|
||||
## So what now?
|
||||
|
||||
|
||||
|
||||
Well, Gitea actually provides us with a good step in the right direction. Gitea has a feature to *mirror* repositories from GitHub to your self-hosted instance, so it's not too difficult to mirror your entire GitHub user to Gitea. You can self host *and* reap the benefits of GitHub's [network effect](https://en.wikipedia.org/wiki/Network_effect) at the same time. And if your GitHub repos were ever to get taken down like [youtube-dl](https://github.com/github/dmca/pull/8127), you'll still have all the perks of self-hosting a mirror.
|
||||
|
||||
What about Matrix (or is it styled [Matrix]? Looks cooler!)? For this example, Matrix allows you to set up self-hosted *homeservers* and *federate* them with the larger Matrix fediverse. While the vast majority of people just register with the default matrix.org like a centralized chat app, there's a healthy number of alternative homeservers out there. And this, here, is a glimpse towards an actually feasible solution to the problem.
|
||||
|
||||
|
||||
## The solution?
|
||||
|
||||
A few months ago, there was a big debate about whether it was right for Facebook and Twitter to ban Trump from their platforms. But no one asked whether *these companies should have this power in the first place*. The internet is decentralized and difficult to regulate by nature, so if Trump had instead used something like Matrix, his organization would have just set up their own homeserver that no one else would have any control over. Instead of monoliths ruling over a centralized monopoly, we could have hundreds or thousands of small servers for different companies, groups, and organizations, each with full control over their own server, and let the free market and perfect competition do its magic. (By the way, free markets should be thought of as just a *tool* to get the socially optimal outcome, not a laissez-faire rule to solve everything. Free markets simply don't work in most cases.) With an architecture like this, if one server got too big and abusive, it wouldn't be hard to just move over to another one (Matrix has yet to actually implement this, but it's coming!).
|
||||
|
||||
Anyways, traditional self-hosting is quite fun, too, especially seeing how much I've accomplished in two weeks. I can definitely say that self-hosting is not for the faint-of-heart!

After one month of self-hosting, if there's one thing I've learned, it's that self-hosting sucks. As I've said in a [previous post](https://ta180m.github.io/blog/2021/04/08/self-hosting-is-not-the-solution.html), self-hosting is not the solution to our privacy woes. So why exactly does it suck so much? Here's a short timeline of the past month:
|
||||
|
||||
- My Discord-Matrix bridge goes down over a weekend and I don't find out for several days. When I try to restart it, I get all sorts of weird Node.js errors about better-sqlite3. After hours of trying to fix it, I finally just remove all occurrences of SQLite from the code since I use PostgreSQL anyways.
|
||||
|
||||
- Nextcloud Mail stops working. I finally filed an [issue](https://github.com/nextcloud/mail/issues/5007) on their GitHub repository and it turns out it was PHP 8.0.5's fault. Updating it fixed my problem. Who would have thought?
|
||||
|
||||
- Collabora CODE is super sluggish. Nextcloud's built-in CODE server happens to be a joke, but setting up a standalone server isn't trivial, either. Compounded with terrible documentation, you have the perfect recipe for a wasted day of debugging!
|
||||
|
||||
- Grafana/Zabbix really sucks. Bad documentation strikes again! This one wasted at least six hours...
|
||||
|
||||
- NFS is terrible. Why do we have to edit `/etc/fstab` like it's the 1990s? Why?
|
||||
|
||||
Of course, a few good things happened, too. I finally got "DIY cloud gaming" to work a lot better, by using X forwarding and VirtualGL. `vglconnect` is the best remote desktop app I've ever used. I even got sound to work with `PULSE_SERVER=client_ip_address`! Yes, FlightGear works and isn't super laggy somehow, osu! works with `pulseaudio-alsa` so the nefarious PulseAudio can hijack the role of ALSA, the cursor capture in Minecraft and Minetest isn't all weird like it is in VNC, and, of course, I can get a decent FPS in SuperTuxKart now. Yay for gaming, not so much for all the other broken and badly designed and badly documented stuff.

[suckless.org](https://suckless.org) really hates [the web](https://suckless.org/sucks/web/). I'll quote them directly:
|
||||
|
||||
> *It has enabled the global information exchange, mass surveillance, studies in social control, allowed revolutions, made a fortune for many billionaires and in the meanwhile ruined our climate: the web.*
|
||||
|
||||
> *There is an industry which is specialized on extending the resource usage to display just some characters on your display. Millions of jobs are based on outputting HTML in an inefficient way. Look at PHP and all the techniques to extend its "scalability". It is not scalable, it's a prototyping language. Not to mention all its syntactic irregularities. Nowadays classes on classes on classes with getter and setter functions define buttons which can be stripped down to just a simple character string. The web is the practical example why corporate software development does not work and never will. It only ruins our environment, sanity and many brains which could be used for the better of humanity.*

> *PHP was used as the primary example for how interpreted languages produce resource waste. There were optimisations for compiling PHP to C++(!). But this is just a way to allow the mass of programmer sheep to go on and sleep calm at night.*
|
||||
|
||||
|
||||
But why? How did web go from something to make all of humanity's knowledge available and connect people around the world turn into *this*?
|
||||
|
||||
To understand, we must first go back to 1995. You're probably thinking, that's when the Internet first started taking off, right? Nope, this is when Java was released.
|
||||
|
||||
|
||||
## The origin
|
||||
|
||||
What does Java have to do with our current Internet mess? Everything. The date was 1995 May 3, a day that altered the course of programming history. The sad saga of the Internet begins here, with the release of Java.
|
||||
|
||||
What was Java all about? What new concept did it try to bring to the table? That's right, **Write Once, Run Anywhere (WORA)** (also known as [Write Once, Run Away](https://stgray.com/quotes/javaquotes.html)). Most programmers are lazy, and writing apps for every different OS variation is a boatload of work. I mean, look at Windows and Linux. They are completely different beasts, right down to the core. To begin with, they have different [line endings](https://www.hanselman.com/blog/carriage-returns-and-line-feeds-will-ultimately-bite-you-some-git-tips) which always seems to pop up in places where you expect it the least. Anyways, here comes Java, and suddenly, you can *write once*! Magic! Of course, early Java implementations didn't exactly deliver on performance, not until optimizations like JIT became a thing, but still! This was a revolution.
|
||||
|
||||
So, why did I just dump all of this information? Because here we see the crux that is the crap of the modern web. It all comes down to programmer laziness and convenience. And Java was the beginning. (Well, you can find examples of this much earlier, but I'm leaving them out of this post)
|
||||
|
||||
The web was also beginning its meteoric rise around 1995. The early web was originally meant only for [serving HTML](http://motherfuckingwebsite.com/), but then, some lazy programmer put 2 and 2 together and came up with Java web applets (hey also turned out to be hideous security holes). Now you could not only WORA, but *also* deliver your crummy little Java apps *over a browser*. No more installing stuff (except for Java). It was that easy!
|
||||
|
||||
And people took great advantage of it. Soon, all the major browsers, or at least the ones that wanted to be competitive, started shipping with support for Java applets. And that was the beginning of the idea that the humble *browser* could be the vector for this infection.
|
||||
|
||||
But no one uses Java applets anymore. In fact, they were officially discontinued in 2018 for being such cancerous security holes. While Java applets have not been able to survive the turbulence of time, a similarly named thing has.
|
||||
|
||||
|
||||
## Java... Script!
|
||||
|
||||
Yep, that's right, JavaScript! The programming language that sucked so much on release that the creators named it after another popular language to build up false hype for it. The inefficient, bloated assembly language of the web. The language that has not only dominated the web but also has been ripped out of its already unfornate role and shamelessly promoted as the future of apps.
|
||||
|
||||
Let's tackle the first objection: does JavaScript suck? The short answer is, [absolutely](https://medium.com/javascript-non-grata/javascript-is-a-dysfunctional-programming-language-a1f4866e186f) [yes](https://hackernoon.com/the-javascript-phenomenon-is-a-mass-psychosis-57adebb09359)! There are tons of criticism circulating on the web, so I'm not going to delve too deeply on it.
|
||||
|
||||
On to the next concern: when you open a tab, what you are doing is effectively creating a new virtual machine. A freaky JavaScript/WebAssembly virtual machine, that is. For every tab! (Of course in the name of security!) Ever wonder why browsers are so notorious for consuming RAM? Well, this is it. That's what you get for running 10 VMs simultaneously!
|
||||
|
||||
What about lightweight browsers? I can think of a few of the top of my head: [Midori](https://astian.org/en/midori-browser/), [Falkon](https://www.falkon.org/), and [Links](http://links.twibright.com/). But throw some modern websites at them, and they'll crash and burn. That's right, the web has degraded so far into the JavaScript quagmire that the only way web browsers can actually be useful for 99.99% of people is to bloat them up so they turn out like Firefox.
|
||||
|
||||
Now that's pretty bad, but it only gets worse. Not only has JavaScript conquered the web, but it's also been encroaching and invading the space of desktop apps. Just look at [Electron](https://medium.com/@boundarybreaker/electron-is-a-hulking-monstrosity-of-a-wora-framework-and-it-needs-to-be-replaced-25e9d849b0e). GNOME has been integrating [JavaScript](https://gjs.guide/) everywhere into its desktop. Look at the proliferation of JavaScript frameworks, not limited to Node, Vue, Ember, Angular, React, Meteor, and more. This is an invasion!
|
||||
|
||||
So why is this happening? You don't have to look back any farther than Java's WORA mantra. At the end of the day, it's the toxic combination of vast OS differences and sheer programmer laziness. There is no way to escape the nightmare of supporting multiple operating systems. If you cheat and take the WORA route, you pay for it with your bloated, inefficient, unmaintainable apps. I haven't even started ranting about PHP but the message is the same.
|
||||
|
||||
So is there anything we can do about this? The short answer is not really. No programming language is perfect, but JavaScript is the polar opposite of perfect. Sure, there are better WORA languages and frameworks out there, but the underlying problems are here to stay. Programmers will always be lazy, and state of operating systems in 2021 is rather depressing and looks unlikely to improve anytime soon. If you ask me, the future looks very bloated indeed.

*Originally posted on my [old blog](https://github.com/Ta180m/blog/blob/main/_posts/2020-12-26-why-wms-suck.md)*
|
||||
|
||||
|
||||
WM fans, don't kill me for saying this, but window managers suck. To see why, let's examine the process of installing and configuring a WM.
|
||||
|
||||
|
||||
## Installing a WM
|
||||
|
||||
OK, I'll admit that this step is much faster. Most WMs are only a few megabytes and take a few seconds to install, even with slow package managers like `urpmi`. Try installing something like KDE Plasma on Mageia or even Arch. It's going to take a while. (Maybe go eat a snack while it's installing?)[/blog/2020/08/25/wsl-2-gnome-desktop.html].
|
||||
|
||||
|
||||
## Configuring a WM
|
||||
|
||||
Now that you have your favorite WM installed, what next? If you're hardcore, you probably already have a repository with your dotfiles and configs all ready to go, but what about an un-configured WM? Well, it will probably be *functional* in terms of managing windows, but it probably requires a lot more work to get it to do anything useful. You'll be stuck editing config files for several hours to get something on the level of a desktop environment. All desktop environments ship with a settings app to modify essential settings such as monitors and such. Using a WM? Well, good luck with `xrandr`, although it's not *too* hard. Now what about screen scaling? Now you have to edit `.Xresources`! And what about adjusting the screen color to make it easier on your eyes? Oops, you'll need a separate program to do that! It's orders of magnitudes nicer to have all of these common tweaks in one place, in a DE.
|
||||
|
||||
I'm going to use the example of KDE Plasma some more, since it exemplifies a nice, well-rounded desktop environment. One of the key benefits of Plasma is its excellent integration with the KDE application suite. Sure, not every DE has a very complete set of applications, but it's loads better than anything you can do with a WM, in addition to a drastically lower amount of tedious work to set everything up.
|
||||
|
||||
The most common criticism of desktop environments is that they are "bloated" and "resource-hogging". And yes, I'm going to have to concede this one to the WM fans, since window managers tend to be very spartan and minimalistic. I even use i3 sometimes when working with very intensive software, such as with the [macOS VM](/blog/2020/11/18/fun-with-qemu-kvm.html). But every time I use i3, I'm constantly reminded of the Plasma features that I take for granted: a consistent icon theme, screen scaling for my high DPI monitor so the text can actually be legible, adjusting the screen color, mouse scroll direction, Krunner, and much more. Never forget Krunner. The single most important KDE app. Too bad it's glitchy with i3. I did end up fixing some of those things, but it doesn't feel *right*. I could put in more time, but there's just something *missing* about i3. It's incomplete.
|
||||
|
||||
If you go on Reddit or do a DuckDuckGo search, you'll find plenty of examples of beautiful, heavy-customized WM setups. The emphasis on heavy-customized. It takes hours and hours of work to create something like that! Sure, you can download their dotfiles and set it up on your own computer, but it still doesn't feel quite the same as using a mature, well-rounded DE like KDE Plasma. Desktop environments are designed to make your life easier, even if it doesn't feel like it sometimes. WMs are really for people who have too much time on their hands and *need* that ultimate customizability. For everyone else, stick with your desktop environment.
|
||||
|
||||
|
||||
## What about using [i3 with Plasma](https://userbase.kde.org/Tutorials/Using_Other_Window_Managers_with_Plasma)?
|
||||
|
||||
Meh. Kwin is pretty good and does dazzling compositing effects. Too bad it can't tile.

|
||||
|
||||
|
||||
If I had to name the single thing that I most hate about Windows, it would probably be Windows update. I have a long and complicated history with Windows update. Throw in [Windows Insider](https://insider.windows.com/), and you have the perfect recipe for disaster!
|
||||
|
||||
|
||||
## A close encounter
|
||||
|
||||
So my experience with Windows update begins about two or three years ago, when I noticed the cute ninja cat of Windows Insider lounging at the bottom of the Updates panel in the Windows 10 settings app. (Check for yourself! It's a ninja cat.) Curious, I clicked on it, and I was piqued by the thought of "exploring new Windows features" and such. Well, they say curiousity killed the (ninja) cat, and my first Insider build that I installed wasn't exactly the most stable thing. Yeah, I got a GSOD (I completely freaked out) and hurriedly reverted back to a regular build. Anyways, I stayed away from Insider for a while.
|
||||
|
||||
|
||||
## The disaster really begins
|
||||
|
||||
Eventually, stories about Insider's spectacular WSL 2 support drew me back, and soon, I was back on an Insider build. [19603](https://blogs.windows.com/windows-insider/2020/04/08/announcing-windows-10-insider-preview-build-19603/) to be exact. Ironically, WSL 2 was added to regular Windows not long after, but anyways, 19603 was surprisingly stable. No crashes. No GSODs. Maybe a few minor graphical glitches occasionally, but I was enjoying WSL 2.
|
||||
|
||||
Then, new stories emerged. OpenGL GPU support in WSL 2! Or some combination of buzzwords to that effect. I was hooked. I needed that new Insider build, number [20161](https://blogs.windows.com/windows-insider/2020/07/01/announcing-windows-10-insider-preview-build-20161/). (Actually, GPU support might have been added in a previous build, but I didn't hear about it until after they released 20161) And 20161 was, as you might expect, pretty unstable. I think I got at least three GSODs during a few days of usage, so I impatiently waited for the next build to drop.
|
||||
|
||||
This was the one that killed my PC. Build [20180](https://blogs.windows.com/windows-insider/2020/07/29/announcing-windows-10-insider-preview-build-20180/). I don't know what happened. Maybe it was because I left Windows alone to update for a few hours, and came back to see it totally wrecked. Maybe it was because I used some [DSIM hacks to enable Hyper-V on Windows Home](https://github.com/Ta180m/Windows/blob/master/hyper-v.bat). Maybe my RAM had a memory error in the middle of the update. Maybe a bit flipped somewhere and derailed everything. But whatever the cause was, Windows was in a *very* bad shape after the update.
|
||||
|
||||
Yeah. That was one of the reasons, probably the most down-to-earth reason, why I switched to Linux. The USB ports started acting weirdly, I experienced popups telling me stuff was wrong with Task Manager, when installing software it would fail in the middle for no reason, and a lot more. My NVIDIA graphics card was no longer detected by Windows `DSIM` and `SFC /scannow` stopped working. When they said unstable, I didn't know this was what could happen.
|
||||
|
||||
I tried a lot of stuff. I tried searching up my problems online. No help. I tried to update Windows to the next build, but it kept on failing in the middle. No help. So, I did the logical thing: switch to Linux, and I've been pretty happy ever since. No of the problems ever followed me to Linux. (Of course, the NVIDIA card gives me plenty of problems on Linux, but they aren't related to ones I was having with Windows)
|
||||
|
||||
But something was still bugging me. A few weeks ago, I recieved another email from Windows Insider telling me to update my build, since it was no longer going to be supported. If I didn't update by January 21 (or something like that) I wouldn't be able to boot up Windows!
|
||||
|
||||
I was stuck. I didn't know what to do. Reinstall Windows? I didn't want to go through the trouble. After all, I never use Windows except for the occasional gaming. So, I tried my last resort: Windows update.
|
||||
|
||||
|
||||
## Windows update to the rescue!
|
||||
|
||||
Yes, Windows update, the very same thing that had crippled my PC. Many of the online guides had recommended trying to update Windows to solve some of the problems that I was having. Since my build was expiring, I decided that it wouldn't hurt to try, other than wasting two hours of my time.
|
||||
|
||||
I started by moving some large files out of my Windows partition to ensure there was sufficient space during the update. Then, I enabled the "optional telementry" that must be enabled for downloading Insider builds and got started. The update lasted around 90 minutes. It stalled for a while at certain percents several time, but it eventually completed. Somehow.
|
||||
|
||||
When it was done, I logged back in, and it did the usual "Hi." ritual. Finally, it dropped me back on to my desktop, and I tested a few things to see if my Windows installation had been fixed. Nothing suspicious or weird happened, which was definitely a relief. OK, so it looked good so far. It also felt a lot faster and smoother, but that was probably because I disabled Windows Defender. (I don't need it if I only use Windows to play a few games once a month)
|
||||
|
||||
I've been on build [20279](https://blogs.windows.com/windows-insider/2020/12/14/announcing-windows-10-insider-preview-build-20279/) for several days now. Since I rarely use Windows, I don't know the full extent of its stability or lack of stability, but it seems like *all* of my problems from before have been fixed. Weird.
|
||||
|
||||
One final observation: How come proprietary operating systems still take forever to do updates? Can't they learn from Linux? Why do they need to take 90 minutes even for updating from one build to the very next one? Sure, I can excuse it if it's one update every six months because a lot could have changed (Ubuntu version updates also take a while) but Windows shouldn't have needed 90 minutes for something like build 20161 to 20180. And that update seriously broke my computer. Well, it looks like my latest build 20279 won't expire until October, so I might just procrastinate the next update until then.

What a perfect time to build a PC: massive supply chain disruptions, cryptocurrencies driving up GPU prices through the roof, (scalper) bot wars, and a pesky little thing called the coronavirus murdering 2.5 million people (that last one probably sounds completely alien to anyone before 2019). Just perfect!
|
||||
|
||||
Anyways... for over 40 days since buying an overpriced 5600X (because of insane taxes, that's what), there were a grand total of zero deals. OK, fine, there were a few motherboards that were discounted a little bit, but nothing big. The drought of price drops literally desiccated my hope of being able to complete my build anytime soon at a reasonable price. My build was indefinitely on hold.
|
||||
|
||||
But then...
|
||||
|
||||
Yes, I'm trying to build up suspense even though everyone knows what's going to happen.
|
||||
|
||||
Wait, let me first back up a bit and give some context: I had set up alerts for a ton of motherboards: cheap ones, high-end mainstream mobos, even ones I never though I would buy. I had my eye on the [Extreme4](https://pcpartpicker.com/product/zsfFf7/asrock-b550-extreme4-atx-am4-motherboard-b550-extreme4) since it had been relatively cheap when I was planning my build, but the price simply refused to go down again.
|
||||
|
||||
The days went on, and no alerts were triggered. OK, some of them were, but they were all for really bad deals that only shaved off a few percent.
|
||||
|
||||
But nothing could have prepared me for a 40% price drop.
|
||||
|
||||
Yes, it was that delicious.
|
||||
|
||||
On the night of February 21, the price of the [PG Velocita](https://pcpartpicker.com/product/ZPDkcf/asrock-b550-pg-velocita-atx-am4-motherboard-b550-pg-velocita) crashed over 40%. Ludicrous! I know! Instant buy!
|
||||
|
||||
I ended up snagging the mobo at around $132, nearly $90 lower than its MSRP, and even cheaper than the lowest price of the Extreme4. And this is no cheap mobo, with its stellar VRMs. According to reviews at least. I still have no idea how much pain it's going to take to actually get it to boot with the 5600X since at release, many motherboards needed a BIOS update for the new processors. Hopefully the BIOS on mine is compatible...
|
||||
|
||||
Anyways, AMD is announcing a new graphics card today. Yes, when all graphics cards are being sold at twice their MSRP. Perfect timing.

Last Wednesday, March 10th, was going to be *the day*. The day I finally could complete a functioning (but incomplete) build. My slightly overpriced RAM sticks (RAM prices were creeping upward sinisterly so I decided I probably shouldn't wait longer. Probably a bad move, too, but whatever.) were arriving, and it was going to be momentous. I was going to boot up an Arch USB drive, SSH in, and get the party going.
|
||||
|
||||
|
||||
|
||||
Yeah... that didn’t exactly happen.
|
||||
|
||||
The first ominous sign was that the motherboard shipped with an old BIOS. According to anonymous Redditers, that particular version could boot to the BIOS menu, but no further. It wasn’t old enough to be a major problem, since I could probably still do a BIOS update, but it was definitely the first thorn in a long line of problems.
|
||||
|
||||
So on the big day, the RAM sticks arrive a few hours before Amazon predicted; always a good sign. It was the final piece of the puzzle, and now my build could finally start functioning! Installing the RAM went smoothly too. But everything basically fell off a cliff from there.
|
||||
|
||||
The first glaring indicator of an impeding disaster was that when I pressed the power button, the lights and fans whirred as expected, and the motherboard went through its POST, but monitor stayed pitch black. No signal.
|
||||
|
||||
Aw man, I didn't have a GPU, so... no signal! I was going to have to do this blind. No problem, though, since I could SSH in, right?
|
||||
|
||||
Well... let's not get ahead of ourselves. I still need to boot up Arch, right?
|
||||
|
||||
So I plug in the USB drive, and try to boot up, but oops! I can't see anything! So I have no idea if I really booted up or not, but according to `nmap`, no new network devices popped up, so I'll take that as a no.
|
||||
|
||||
I retrace all my steps, and recognize that SSH isn't correctly set up on the default install images. So... I go through the long detour of creating my own [Archiso](https://wiki.archlinux.org/index.php/Archiso) with SSH ready to go, and 15 minutes and one `dd` later, my USB drive is ready!
|
||||
|
||||
I do the boot sequence again (actually, several times) but still it doesn't work.
|
||||
|
||||
Oh wait! The old BIOS! It's probably unable to boot Arch because of the old BIOS! I need to update it! An fortunately enough, I don't have a display.
|
||||
|
||||
I hate manufacturers that create convoluted BIOSes — especially ones that are absolutely impossible to navigate blindly! It doesn't help that BIOS updates tend to shuffle around the settings. I tried watching a YouTube video of someone showing off the BIOS, but it was a lost cause. It was impossible to do without a display.
|
||||
|
||||
Alright, so I got to find a GPU... dddaaarrrnnn!!!
|
||||
|
||||
The thing about buying a GPU right now is that everything's in one of two states: sold out, or marked up at extraordinary prices. [Five-year-old GPUs are fetching nearly two times their original price](https://www.amazon.com/GeForce-192-bit-Compatible-DirectX-Graphics/dp/B08YCRY3V7/ref=sr_1_1?dchild=1&keywords=geforce+gtx+%221060%22&qid=1615860494&sr=8-1), and the [latest releases](https://www.techradar.com/news/current-nvidia-rtx-3000-gpu-prices-are-so-much-worse-than-we-thought)? Just forget it.
|
||||
|
||||
Why is this happening? Well, it happens to be the perfect storm:
|
||||
|
||||
1. **COVID-19**: Everyone's stuck inside, and what to do to pass the time? Game, of course! Everyone's building PCs, and the supply simply can't keep up, and prices are balooning into the stratosphere. But that's not it.
|
||||
|
||||
2. **Cryptomining**: With Bitcoin and Ethereum smashing price records, cryptomining is back in full swing now. With one of the latest GPUs, you could be making *$5 a day!*. Mine for two months, and that'll be $300. You'll be willing to pay much higher for GPUs, pushing prices into the mesosphere. Yeah, Nvidia's messing with the BIOS of their latest RTX 3060, but will it help? [Not much](https://www.theverge.com/platform/amp/2021/3/16/22333544/nvidia-rtx-3060-ethereum-mining-rate-limit-unlock-driver).
|
||||
|
||||
3. **Component shortages**: The demand right now is overwhelming, but what about supply? It doesn't look very rosy either. In fact, quite the opposite. Manufacturers are trying to churn out electronic devices as fast as they can, and GPU components like DDR memory is in very short supply. Prices are skyrocketing into the thermosphere now.
|
||||
|
||||
4. **Tariffs**: Yep, even Trump has something to do with this. His last round of tariffs, this time including graphics cards, are the perfect cherry on top. Now prices are way up in the exosphere. Just great!
|
||||
|
||||
Of course, [there are other reasons as well](https://naturecheck.org/2021/03/15/cpu-and-gpu-availability-and-pricing-update-march-2021/), such as companies focusing more on CPUs and other more profitable parts, but GPU prices just seem to keep on going up.
|
||||
|
||||
With prices this high, who's actually buying the GPUs now? There has to be at least someone buying them.
|
||||
|
||||
Well, it's probably people who are extremely price inelastic or people who know absolutely nothing about normal GPU prices. Or just extremely wealthy people.
|
||||
|
||||
Even at the local [Micro Center](ategory/4294966937/video-cards), all they have now is some extremely overpriced Quadros and a few GTX 710s that are even slower than my laptop's current GPU. Doesn't look to good to be buying GPUs now. I *could* buy one since they aren't as overpriced as the ones on eBay, but that's a huge hassle I don't want to go through if I don't have to.
|
||||
|
||||
One last thing: Radeon 6700 XT launch on Thursday. It's way out of my price range, but perhaps it could be the beginning of better stock availability? Who knows. A Bitcoin or Ethereum crash could do the trick, too.
|
||||
|
||||
So that kind of rules out the option of buying a GPU right now.
|
||||
|
||||
But... I only need it for one or two hours, to update and set up the BIOS. What about borrowing a GPU?
|
||||
|
||||
Although promising, this only led to a dead end. My laptop's (discrete) GPU doesn't have an output port since it's part of a hybrid graphics system, so that won't do (among other possible problems, of course). The old Dell Dimension 4100 rotting in the basement has an ATI Rage 128 from 1999, with a *stunning* 32 MB of RAM clocked at 250 MHz, but it has the wrong connecter, AGP, instead of the current PCI-e. My friend has a desktop, but with... integrated graphics. I asked a few other people, but none of them had GPUs they could loan me.
|
||||
|
||||
It looks like my only options now are: asking more people to borrow their GPU, buy an extremely overpriced GPU and possibly sell it, or just wait. That last one doesn't look to fun, but it might just be the best option here.
|
||||
|
||||
It's quite frustrating that the only obstacle in the way of finishing my build is a GPU for an hour. I guess I now have a $666 mega paperweight sitting in my living room. Perfect!

The [Great GPU Shortage](https://www.digitaltrends.com/computing/gpu-shortage-q3-2020-double-triple-price/) continues to [smash](https://www.theverge.com/2021/3/23/22345891/nvidia-amd-rtx-gpus-price-scalpers-ebay-graphics-cards) [records](https://www.extremetech.com/gaming/321129-ps5-availability-is-improving-but-gpus-prices-are-the-worst-weve-ever-tracked). We live in ludicrous times indeed, where it's considered lucky to win [a lottery to buy a $330 GPU... at a $200 markup](https://www.reddit.com/r/buildapcsales/comments/mca471/meta_newegg_souffle_3060_3090_51999/)! The barometer of Bitcoin and Ethereum prices continues to skyrocket, and my chances of finally getting a GPU and finishing my build were dimming every day with no end in sight.
|
||||
|
||||
But finish my build I did, with a GPU that ended up costing a grand total of... **$0**. (OK, maybe a dollar for the gas I used, but it was basically free.) How'd I do it? It's actually surprising simple.
|
||||
|
||||
|
||||
|
||||
1. Join a Discord with people in your area. (I normally don't recommend Discord since it's a privacy nightmare, but welp, [network effects!](https://en.wikipedia.org/wiki/Network_effect))
|
||||
|
||||
2. Socialize with the other people so no one thinks you're a bot.
|
||||
|
||||
3. Ask if anyone is getting rid of old graphics cards.
|
||||
|
||||
4. Follow up any offers with DMs.
|
||||
|
||||
5. Profit?
|
||||
|
||||
Yep, do these five simple steps and you'll have *free* GPU in no time!
|
||||
|
||||
There are a few gotchas though... you'll only get cards that "cost less than a pizza and a pizza runs faster graphics than this card". Also, the other person wasn't even sure if the card worked or not, but I lucked out and it worked perfectly.

It's time to go full circle! I first started planning my build using [Logical Increments](logicalincrements.com/) and [PCPartPicker](https://pcpartpicker.com/) and I can't appreciate how much they've helped me the confusing world of PC building. Now that my build is "finished", or more accurately, functional, it's time to [publish it on PCPartPicker](https://pcpartpicker.com/b/GnV7YJ)!
|
||||
|
||||
Here's some anticlimactic images of the completed build:
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
Here's the writeup that I did for the build:
|
||||
|
||||
What a perfect time to build a PC: massive supply chain disruptions, cryptocurrencies driving up GPU prices through the roof, (scalper) bot wars, and a pesky little thing called the coronavirus murdering 2.5 million people (that last one probably sounds completely alien to anyone before 2019). Just perfect!
|
||||
|
||||
You just have to admire the perfectness of this perfect desktop/server/workstation build. And as an extra bonus, it's $666.66, just like the original Apple I. OK fine, not quite, but it's close.
|
||||
|
||||
And admire how well balanced the CPU and the GPU are. Just imagine this setup at 4K 144Hz...
|
||||
|
||||
Anyways, I first started planning for this build in November, and it only took... 5 months of patiently (actually impatiently) waiting for deals. And I did get some good deals, including the PSU for $20 less and the motherboard for a stunning $90 off. The motherboard came with an old BIOS, but fortunately it could boot to the BIOS setup screen to let me update it for my Zen 3 CPU.
|
||||
|
||||
Getting the CPU involved lurking in a Micro Center Discord for months watching for days with stock, but it finally payed off when I managed to get the 5600X at MSRP, albeit with some pretty hefty taxes.
|
||||
|
||||
Next up was RAM, but prices kept trekking upwards! I finally pulled the trigger and bought it at $86, but taxes brought it up to $94.
|
||||
|
||||
The final ingredient was the GPU. For a few weeks, all that was between me finishing this build was a GPU so I could get a display output for configuring the BIOS and installing Arch Linux. I managed to snag the GPU for free (OK, maybe a dollar for the gas I used, but it was basically free) by asking on a Discord server if anyone was getting rid of really old graphics cards, and I got this great deal! 100% off MSRP! Still, this card is as powerful as you would expect from a free GPU, so I guess I'm not going to be doing any gaming any time soon. For server stuff, it works perfectly fine.
|
||||
|
||||
As for the case and CPU cooler... who needs cases anyways? Cardboard box for the win! And stock coolers work perfectly fine. Sure, I can't boost past 4.5 GHz, so I'll probably have to get an aftermarket cooler eventually, but...
|
||||
|
||||
Anyways, it's been a long journey. Hopefully GPU prices can plummet soon so I can replace my temporary graphics card with an actually decent one. And I still need a real case, an HDD, and a WiFi adapter... Oh well, I guess this build isn't finished quite yet!

|

|

Over the past week, I've been getting my new build set up. It's been quite satisfying: I'll run into more than my fair share of issues, but problem solving for the win!
|
||||
|
||||
The OS installation went relatively smoothly. Partitioning disks was a bit tricky but I got it to work. I wanted to try out `systemd-networkd` and `systemd-boot` for my new server, and I had to spend some time researching documentation. One of them worked perfectly, the other one not so much, so I ended up sticking with the tried-and-true NetworkManager. I also got SSH and VNC working as well, so I was off to great start.
|
||||
|
||||
My first major headache was XMP. To but it simply, enabling XMP always caused me to fail to boot, so something was definitely wrong. I tried various voltages and frequencies, at the highest I could get it to go was 3533MHz, just 66MHz below my RAM's rated speed.
|
||||
|
||||
After coming through online forums and dozens of Reddit posts, I finally found a solution. An anonymous Redditer suggested changing VDD_SOC to 1.00 V to someone with a similar solution, so I gave it a try. Bingo! It worked and my RAM crushed the [RAMspeed](https://openbenchmarking.org/test/pts/ramspeed) benchmark.
|
||||
|
||||
Next! My next challenge was to set up Nextcloud. Fortunately, ArchWiki has a [nice guide](https://wiki.archlinux.org/index.php/Nextcloud), updated and refactored for Nextcloud 21 and there are some other [good ones](https://thepenguin.eu/2018-06-17-how-to-set-up-your-own-cloud-using-nextcloud-on-archlinux/) out there, so that went surprisingly smoothly as well. I also had to obtain a domain for my server, but the [GitHub Education Developer Pack](https://education.github.com/pack) came to the rescue! The most difficult part was probably SSL certificates since I'll never done it before, but it worked out in the end. `certbot` for the win!
|
||||
|
||||
Anyways, my biggest challenges still lied ahead. Matrix.
|
||||
|
||||
[Matrix](matrix.org/) is a great protocol. There's a nice [public homeserver](matrix.org/) that you can try and get your friends to sign up for. But still, it's public and owned by someone else. Plus, you can't run some bridges with it. So, that left me with the seemingly easy task of setting up my own homeserver.
|
||||
|
||||
Way easier said than done. Installing the reference homeserver, Synapse, is straight up hellish. The ArchWiki was marginally helpful. The official documentation was too terse. It didn't make my life easier that I wanted to configure [delegation](https://github.com/matrix-org/synapse/blob/develop/docs/delegate.md) to run my homeserver on a subdomain but show as running on the main domain, but I finally found a [guide](https://ajl.io/matrix-synapse-server-setup-guide/) that would help me do it.
|
||||
|
||||
It took... a while. I ran into numerous problems, ranging from forgetting to `cd` into `/var/lib/synapse` for the homeserver installation to having SSL certificate problems that I finally fixed by issuing one for all my subdomains. Phew. I still had one big challenge still remaining.
|
||||
|
||||
The [https://en.wikipedia.org/wiki/Network_effect](network effect) sucks. All my friends use Discord. Fortunately, I had picked Matrix partly due to its strong bridge support. I tried giving [mx-puppet-discord](https://github.com/matrix-discord/mx-puppet-discord) a shot and it worked perfectly!
|
||||
|
||||
However, there's also a package for it in the [AUR](https://aur.archlinux.org/packages/mx-puppet-discord-git/) that comes with some extra goodies such as a systemd service. What comes next? Well, I'll quote my post on the AUR exactly:
|
||||
|
||||
> For some reason, after editing `/etc/mx-puppet-discord/config.yaml`, when I run `node /usr/lib/node_modules/mx-puppet-discord/build/index.js -c /etc/mx-puppet-discord/config.yaml -r -f /root/registration.yaml` as root, the command never stops running. Checking my active processes, it doesn't even seem like node is doing anything. The same thing happens with `node /usr/lib/node_modules/mx-puppet-discord/build/index.js -h` which should print the help message. Does anyone know why this is happening? Perhaps something is wrong with my node installation?
|
||||
>
|
||||
> EDIT: I generated a `registration.yaml` using the instructions in the GitHub repository, and now when I try to start `mx-puppet-discord.service`, I get the error `Failed at step NAMESPACE spawning`.
|
||||
>
|
||||
> EDIT 2: I finally got the original GitHub repository to work. I don't know what's wrong with this package though.
|
||||
>
|
||||
> EDIT 3: I figured out how to fix the `systemd` error: Turns out you need to manually create the `/var/lib/mx-puppet-discord` directory.
|
||||
>
|
||||
> EDIT 4: Finally got a working setup! I first cloned the repo directly from GitHub, configured it, transferred ownership to the `mx-puppet-discord` user and reused the systemd service. Now it works perfectly!
|
||||
>
|
||||
> EDIT 5: Synapse wasn't starting up fast enough on boot for `mx-puppet-discord`, so I had to add `ExecStartPre=sleep 5` to the service file for it to work after a reboot.
|
||||
|
||||
So there you go. That's how you set up mx-puppet-discord, after hours of problem solving.
|
||||
|
||||
I also set up Gitea to mirror my GitHub repositories, but nothing notable happened with that.

*Originally posted on my [old blog](https://github.com/Ta180m/blog/blob/main/_posts/2021-02-09-worst-first-build.md)*
|
||||
|
||||
|
||||
My laptop's starting to get old. I mean, it works perfectly fine for the most part, but open up a few Google Docs at the same time and watch it struggle to load them: its age is starting to show. Or try to run Zoom (sandboxed in a browser, of course) and anything else at the simultaneously, and you'll get an ugly surprise when your Zoom audio starts crackling up really bad *and* the other app lags like crazy. Fun.
|
||||
|
||||
Well anyways, new laptop time?
|
||||
|
||||
Good question. A laptop with the specs I was looking at starts at over $1200 (Ryzen 5, 16GB RAM, 512GB SSD), and add the additional features of my current laptop—touchscreen, stylus, and a dedicated GPU—and you're looking at $1500 price tags. (Subtract $50 to remove the ["Windows Tax"](https://en.wikipedia.org/wiki/Bundling_of_Microsoft_Windows#The_%22Windows_tax%22), but still!) Can we do better?
|
||||
|
||||
Of course. Why are these laptops over $1500? Well, for starters, they are portable and come with lots of other nice things that I really don't need. I basically use my laptop like a desktop the vast majority of the time. Built-in keyboard? No thanks, I have plenty of keyboards. Screen? Nah, I use a monitor with my laptop anyways, so that screen is going to waste. So what's the obvious solution here?
|
||||
|
||||
Get a desktop! Easy. Now the hard part is actually getting one. Prebuilts are usually pretty bad. So I decided to build one.
|
||||
|
||||
OK. New life mission. Alright, how to start? The first step was asking a friend who has a much more vast amount of knowledge about this topic, basically, an "expert", so I did. And I got back a ton of useful links and information that can be boiled down to this: [logicalincrements.com](https://www.logicalincrements.com/) and [pcpartpicker.com](https://pcpartpicker.com/). Great! Now I have some stuff to work with! So I punched the "good" tier (Or was it "great"? Doesn't matter since I changed most of the parts anyways) into PCPP and hooray, I have a plan. Not a very good plan, since I still felt that I could get some better parts for the same price.
|
||||
|
||||
Next comes the period of heavy research. First, bump that 3600X up to a 5600X (good luck finding it though). Switch to an AMD card, since Nvidia drivers on Linux are `mpv "https://youtu.be/iYWzMvlj2RQ"`. Anyways, getting that out of the way, I made a few swaps here and there for a better case, motherboard, and a couple other parts, and hooray, I have another plan. This was around the beginning of December 2020.
|
||||
|
||||
Great, [I have a plan](https://pcpartpicker.com/user/unixkcd/saved/#view=cPjHGX). Now what?
|
||||
|
||||
Well, time to buy the actual parts. Fortunately, PCPP tracks the price history of parts, so it was pretty obvious to buy the SSD now and wait a bit for the other stuff. The 5600X was definitely going to be a headache, and I decided to wait for the new series 6000 AMD graphics cards to be announced. I also set up email alerts for all the parts on my plan.
|
||||
|
||||
OK, let's tackle the 5600X and get it over with. Step 1: join the Micro Center Discord ([Matrix](https://matrix.org/) > Discord), since I live close to a Micro Center and buying locally has the advantage of considerably less competition from bots at the expense of insane taxes. Oh well. Step 2: watch the Discord closely for "drops". Step 3: Go to Micro Center and hope that they haven't sold out since someone posted they had stock on the Discord.
|
||||
|
||||
It took about a month. Micro Center was pretty dry throughout December. But when January came, my fortunes changed significantly as it seemed that the local demand had shrunk dramatically. Perfect! When I finally snagged one in mid-January, there were still about 15 5600X's left, unclaimed for several hours. The stock problems online are definitely the result of bots. Of course, there would still be shortages during the paper launch, but bots significantly exacerbated the issue. Micro Center proves this. Micro Center has very strict no scalping rules, such as only allowing a person to buy a highly in-demand CPU or graphics card once a month. As a result, there's literally no demand for 5600X's now at a local level!
|
||||
|
||||
Alright, got that one out of the way. At this point, I have three parts: a SSD, a PSU that was on sale during Christmas, and a 5600X. Not enough to do anything just yet. And that's where I am today.
|
||||
|
||||
But... you got the 5600X a month ago! What did you do during that month?
|
||||
|
||||
Well, on average, [PC part prices](pcpartpicker.com/trends/) tend to be lowest in November and December. And for the past month, I've been seeing almost nothing other than price rises. The case increased by $30. The RAM increased by nearly $30 and set a new price record. The motherboard is up $35 from its lowest price, only a month and a half ago. Yeah. So if I buy them now, I'll be looking forward to blowing over my initial budget by nearly $100.
|
||||
|
||||
Ironically, if I had bought all the parts in December, I wouldn't be in this situation right now. Even more ironically, I might have been in another tight situation. The B550 motherboards were in need of BIOS updates when the series 5000 processors first came out in their paper launch, and the motherboard I had planned on buying needed an older CPU to update the BIOS. Not like I have an old CPU lying around to do that, unfortunately. So, I waited. To my detriment.
|
||||
|
||||
I really don't know why I didn't buy those parts in December. Those prices make the ones now look like some kind of major supply chain disruption happened or something. (COVID-19 continuing to unleash its wrath?) I don't even want to talk about GPUs. Last summer, people said to wait for the launch of the next-gen GPUs and prices of older ones would go down. Well, guess what happened? When the Nvidia series 3000 and AMD series 6000 launched in that epic paper launch, prices of older ones actually went *up*. WTF??
|
||||
|
||||
Yeah. Pretty bad. Even worse is the fact that if you had bought a Radeon 5600 XT a year ago, it would have cost about $280. Now? You can easily sell it for double, or even 2.5 times the original price, earning a $400 profit plus the additional utility you got out of using it for a year. Terrible.
|
||||
|
||||
So why is all of this happening? Well, the one thing that's been weirdly consistent is that many major retailers are selling these parts *at MSRP*. Why is this crazy? Because the demand is over the roof, with tons of COVID-19 gamers and others looking to build PCs. Jack up the prices a bit, at the major retailer level, and those retailers could be pulling in millions of extra profits. They only have a limited supply, so it's not like they're going to sell less.
|
||||
|
||||
So why don't they do that then? Maybe I don't understand basic economics or business thinking, but raising prices at a major retailer level instead of a corresponding price raise for resells on eBay would result in quite a lot of benefits. Imagine all the hours of productivity loss from pursuing stock drop notifications to fight over some parts where the buyers outnumber the supply by a factor of one hundred to one, or the mounds of money flowing into the pockets of scalpers from marking up prices by a factor of two and reselling on eBay. Why is the 5600X *only* $300 when it's going on eBay for over $400, for instance? This is a particularly benign example compared to graphics cards which sell for over twice the MSRP on eBay. And why don't online retailers have better anti-bot mechanisms in place, such as CAPTCHAs that computers actually *can't* solve?
|
||||
|
||||
Well, enough ranting. Hopefully when I write part 2, there'll be some price drops. For now, doesn't look like it.

|
||||
|

True story: a few weeks ago, I wanted to test out SuperTuxKart but I didn't want to install it on my computer. I had a few options: use a virtual machine and suffer terrible graphics performance, use Docker and suffer the pain of trying to set up graphical acceleration; or use LXC/LXD and suffer the (massive) pain of trying to set up basically anything. I ended up just installing SuperTuxKart to get out of the triple-sided dilemma.
|
||||
|
||||
I didn't know it at the time, but I had the right tool for the job already installed. In fact, the vast majority of Linux systems actually have this tool installed as well. It's called `systemd-nspawn` and it's surprisingly easy to use.
|
||||
|
||||
Let's get started. I'm using an Arch host and Arch container. Other setups should work as well, but using the same OS for the host and container should give you the best compatibility.
|
||||
|
||||
```sh
|
||||
sudo -s # get a root shell
|
||||
cd /var/lib/machines # default directory for nspawn containers
|
||||
|
||||
# create a container
|
||||
mkdir archlinux
|
||||
pacstrap -c archlinux base nano fish sudo neofetch # add more packages here
|
||||
exit # exit the root shell
|
||||
|
||||
# now "chroot" into it
|
||||
sudo systemd-nspawn -D /var/lib/machines/archlinux
|
||||
passwd # set a root password
|
||||
rm /etc/securetty /usr/share/factory/etc/securetty # remove some problematic directories, optionally add them to NoExtract in /etc/pacman.conf
|
||||
useradd -m -s /bin/fish -G wheel ta180m # add a user
|
||||
passwd ta180m # set password
|
||||
exit # exit the "chroot"
|
||||
|
||||
# now the magic happens
|
||||
sudo systemd-nspawn -b -D /var/lib/machines/archlinux
|
||||
# log in with the user account
|
||||
```
|
||||
|
||||
To understand what `systemd-nspawn` does, think of `chroot` but "on steroids". The underlying simplicity of this virtualization method makes it easy to run GUI apps, for example.
|
||||
|
||||
```sh
|
||||
xhost +local: # allow local connections to X server
|
||||
# share pacman cache and graphics cards
|
||||
# may need to bind more directories for Nvidia cards
|
||||
# you must have the exact same drivers on the host and container for this to work!
|
||||
sudo systemd-nspawn -b -D /var/lib/machines/archlinux --bind=/var/cache/pacman/pkg/ --bind-ro=/tmp/.X11-unix --bind=/dev/dri --bind=/dev/shm
|
||||
export DISPLAY=:0 # set the display
|
||||
# now you can run GUI apps!
|
||||
```
|
||||
|
||||
Here's SuperTuxKart in all its glory running in a container with full graphical acceleration!
|
||||
|
||||
|
||||
|
||||
And that's it! Now you have a fast, simple way to test GUI graphically accelerated apps without messing with your host OS. (I still haven't gotten sound to work yet, but it shouldn't be *that* hard...)
|
||||
|
||||
Part of the simplicity of `systemd-nspawn` is that it is more of an extension of the age-old `chroot` instead of trying to virtualize too much like Docker. There's no need to worry about virtual network devices, virtual disks, volumes, or any of that stuff. Sure, that limits it in many ways, but it is still a very powerful OS virtualization method when the host and container are running the same OS. Previously, I had also experimented with [QEMU/KVM](/blog/2020/11/18/fun-with-qemu-kvm.html) for this, but it seems overkill since the host and guest can share much the OS such as the kernel. Of course, full-blown virtual machines have their own horde of problems, such as terrible graphical acceleration unacceptable for testing SuperTuxKart.
|
||||
|
||||
Here are a few possible use cases:
|
||||
|
||||
- Installing 32-bit libraries in a container to avoid polluting the host OS
|
||||
|
||||
- Using proprietary NVIDIA drivers in the container and rendering the host's desktop with free drivers

- One-time testing of apps to avoid installing them on the host

There's one final thing I need to clarify, and that's the title. By worst init system, you probably know which one I'm talking about: systemd. I'm not saying that systemd is buggy and doesn't work well (like btrfs for instance), since it works fine and I've never had any problems with it. The issue with systemd is that it tries to do too much. According to the all-knowing [ArchWiki](https://wiki.archlinux.org/index.php/Systemd):
|
||||
|
||||
> *[systemd] provides a system and service manager that runs as PID 1 and starts the rest of the system. systemd provides aggressive parallelization capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux control groups, maintains mount and automount points, and implements an elaborate transactional dependency-based service control logic. systemd supports SysV and LSB init scripts and works as a replacement for sysvinit. Other parts include a logging daemon, utilities to control basic system configuration like the hostname, date, locale, maintain a list of logged-in users and running containers and virtual machines, system accounts, runtime directories and settings, and daemons to manage simple network configuration, network time synchronization, log forwarding, and name resolution.*
|
||||
|
||||
Whoa! That's a lot!
|
||||
|
||||
Much of the hate that systemd receives stems from these blatant violations of the [Unix philosophy](https://en.wikipedia.org/wiki/Unix_philosophy). systemd does not do one thing and do it well, unlike its predecessors. It does dozens of things, and arguably, it doesn't do them badly, but thought of systemd slowing expanding its grasp on your entire OS is unacceptable to some people. But of course, this begs the question of whether it is really necessary to adhere so strictly to the Unix philosophy, since most big, standalone apps like GIMP and [LibreOffice](/blog/2020/12/25/linux-office.html) obviously violate it.
|
||||
|
||||
Still, systemd is everywhere these days, so it might be better to get used to it. Many of its tools are quite good, and `systemd-nspawn` in particular is exceptional. After watching the proliferation of systemd in the past few years, it's undeniable that it's here to stay.
