Welcome to zzz/tech/
0. All global rules apply: https://zzzchan.xyz/rules.html
1. /tech/ is a primarily SFW board. NSFW is only allowed if spoilered.
2. Keep the topics related to technology and computing.
3. When making a thread, put some effort into the OP. Low quality threads and template threads will be bumplocked. Some low quality threads that have already been bumplocked can be deleted if too much fills up the catalog.
4. For the QTDDTOT thread and the meta-thread, there can be only one unless the reply limit has been reached. If the previous thread is at the reply limit, anyone can recreate those threads. Thread quality rules do not apply to these threads.
5. Low quality shitposting will be met with DELetion or all files in the post being unlinked (frogposting, wojaks, >he doesn't use [insert thing here], Reddit logo spam, etc.). Otherwise, shitposting is allowed but try not to derail threads.

Posting recommendations
1. Try keeping most of your tech support questions, software recommendations, consumer advice, and other questions that don't deserve threads in the QTDDTOT thread. If there is a specific thread for your question, try asking there instead for a faster response.
2. Try not to ask questions that can be found on any search engines. You will most likely be told to search more and not receive an answer.

Make sucks for everything, including the smallest of projects.
That anon is already picking between breaking one platform or using pkg-config because of Make brain damage. His code has a "TODO use strlcpy" comment, he can't feature test for the presence of strlcpy with Make, just figuring out the right concotion of #ifdefs to write for that is more effort than learning Meson and will produce worse results.

The sheer amount of suck in any build system other than Meson is not funny. I've spent way too long fixing Autotools and CMake garbage. I'm fixing an Autotools project right now. Do yourself and the world a favor by not using that stuff.

The gitea instance where I uploaded octaPNG is having connection issues, so I'm (permanently?) moving to another instance: https://git.creepercreep.fr/gillian885/octaPNG

Great examples, thank you.

Those are some very impressive features, especially the way recompilation and dependencies are handled. I'll consider Meson in future projects and maybe this project as well if it grew more complex later on... But for now I think it would be overkill to use Meson for such a small project, especially considering it has a dependency on Python which I would rather not require.
>it's a build time dependency that makes a platform work without breaking others.
Alright, I've added pkg-config as an optional dependency that is used by default.
>I don't see anything wrong with it, but I don't see anything right with it.
If it ain't broke I won't fix it. parg works nicely for octaPNG and is already being maintained by someone else.
>It should be settable through the make command
Good idea. I've removed all the recursive makefiles and implemented only one makefile that accepts pretty much every option you can think of in a configure-like fashion, so it may be used right away in a predictable fashion. I've also made it strictly POSIX-compliant so it now plays nice with bmake, pdpmake, and even nmake for Windows 95. If you have time do check out the implemented options or read the examples of their usage:

I looked around since I don't have time to test out 3-4 build systems right now. Here is what I found about Meson, it is easy to see why it is good from what you and >>5671 said, so I look for the bads instead.
>cross-compiling support is(was?) weaker than cmake, especially when building dependencies that uses cmake
>little flexibility, rigid project layout expectation, you need to format your project just like what meson expects
I also found the good stuff such as better syntax and speed.
Never used it, I can't say how rigid meson is to project structure. But being confined by a build tool sounds like little gain for a lot of restriction. How do you deal with this or are you completely on board with meson's project layout (it is not a problem for you)?
Replies: >>5691
Meson doesn't specify a project layout beyond requiring a dedicated build directory which can have any name.
Cross compiling under Meson is badly documented and buggy. I've also run into a limitation: it won't let you depend on a library on the host and the build machines simultaneously.

Another thing about Meson is that it's not as portable as Autotools or CMake. You can't port your program to 9front or UnixWare 7 with it, and it doesn't support tcc, cparser, or other such obscure systems and compilers. Meson's integration requires adding code to Meson itself to support all of those systems and compilers, whereas Autotools and CMake leave that up to you, so if you put the effort into it, you can probably port your programs to LynxOS and pcc and the like. Well, if you put effort into it, you can add that support to Meson.

I'm this guy btw >>5153. I'm trying to port my stuff to every single system and compiler Meson supports, right now I'm unable to port to any more only because I don't have access to them. I can't get an AIX or HP-UX machine and I can't get nvidia's C compiler. I also need a more modern computer to virtualize GNU/Hurd.

Define your threat model. Are you writing something about ((( them )))? Will that catch glowniggers' attention? Or are you afraid of being cancelled?
If jews and feds are a threat, you need to pay anonymously and connect to your vps anonymously (Tor). If your VPS is shit, you may need that for the slightest of risk. Otherwise, you should be fine if you don't store anything about yourself on your blog. Do full disk encryption if necessary, that will save your ass if they decide to raid drives from racks. If you care about your users, keep zero logs, not even kernel messages. A step further is hosting your site over Tor (and proxy it to clearnet). Keep your blog one way if possible, don't accept user content, it only takes one pixel of cp and a mention of a manifesto to bring you down. Setup alternative communication means for reader feedback, share public keys. Backup your shit and be ready to spin up fail overs. Encrypt (with plausible deniability) your backup and your computer where you typed your blogs, lest they search your drives.
If in doubt, assume the worst.

Stop namefagging
I did do that ctrl+alt+del a lot since sometimes even tty2->power button won't work every other update or the shutdowns just take forever BUT even that sometimes refuse to work since it somehow unloaded my keyboard first before trying to unmount my drives and at one update (arch) systemd even forgot to fucking unmount my drives which I saw in the logs.
Btw the biggest problem was arch defaulting to use systemd coredump.
It would sometimes cause the HDD to be on 100% load when KDE-X11 compositor casually crashes dumping whole 4GB of multiple files on my slow drive and small root partition, it even disgustingly tried to dump shit when my drive was at 0MB left, also crashing the system again, causing it to dump over and over, this is worse than fucking Windows 10 boot loops which I've not experienced but I'm pretty sure it's more workable than having to go through your systemd binary logs just to figure out the root of the problem, well the solution was simple >>1 never had problems ever since I stopped using that shit.

Repost of the Julay /tech/ sticky with some minor edits: https://archive.vn/znAXT
Beginner Info
If you would like to try out GNU/Linux because of https://itvision.altervista.org/why-windows-10-sucks.html, you can do one of the following:
0) Install a GNU/Linux distribution of your choice in a Virtual Machine (preferably using KVM or Oracle VirtualBox for newfriends).
1) Use a live image and to boot directly into the GNU/Linux distribution without installing anything (keep in mind that the performance of live distros might be very different than from distro that was booted from your HDD, as most distros are loaded in RAM and don't include the proprietary drivers for NVIDIA GPUs or up-to-date Mesa libraries in their isos).
2) Dual boot the GNU/Linux distribution of your choice along with Windows (make sure to install Windows first, as it can "replace" GRUB or other UNIX bootloaders, and troubleshooting of Windows replacing your bootloader of choice might be painful for people that just started learning about the Linux kernel)
3) Go balls deep and replace everything with GNU/Linux (you really shouldn't do this, if you don't know what you're putting yourself into, see: https://itvision.altervista.org/why.linux.is.not.ready.for.the.desktop.current.html).

Use your web browser and search engine of choice. Good comparison between them is hosted here:
If not sure which browser to choose, just use the Tor Browser Bundle:
or paste these commands to your terminal emulator of choice (please make sure to first learn what they're exactly doing):

Is there something similar to this for nvidia (proprietary drivers)?

I have tried adding/changing "... video=DVI-D-0:[email protected]" on my grub kernel line but when my PC boots it completely ignores the setting and just uses 60Hz on my monitor instead.
On intel/igpu/motherboard display port the above kernel command line works but when I used another GPU it just sucks:
>ctrl alt F1 makes screen go black (due to 60-75Hz clock changes)
>grub/boot screen is 60Hz until it loads my desktop which is 75Hz causing the monitor to blink off like 5x
It doesn't blink if I used intel igpu, and I could swap to tty1 to tty7 and the clock is set to 75hz all the way (from grub menu). I don't like my tty at 60Hz since it is slow, causes gpu/display to stutter/change clocks which can degrade its life span too.

I just got memed.
Next time I'll only either buy AMD with APU or Intel with IGPU, no mix or match so the screen wouldn't have to blink 5x and blink more when I switch tty. I also recommend you anons do that too.
Replies: >>5615
I've tried all possible grub command line or early kms settings and then finally just setting it all to 60Hz and yet it's still fucked.
Switching to [email protected] from [email protected] would still blink the monitor off due to the graphics(and even audio, or programs) being suspended when switching to tty.
I think nvidia driver is running at userspace or something and halts during the switch (which is kinda terrible unlike with integrated graphics) or maybe it's due to the graphics memory not sharing (dedicated) so it would halt when switching between those.

Well that's it for me, there's no solution. The only solution is either I get iGPU or downgrade and I'm thinking only intel (or more modern AMD) is/are capable of natively getting the tty at higher than 60hz clock rate.
