STFW, you fucking brainlet.
As long as it's a modular PSU I believe any cables should work with it, but do your own research because I've never used third party cables myself before. The company I've heard jewtubers reference a lot for custom cables is cablemod.
They definitely aren't cheap though. There's also this site, which may or may not be cheaper depending on which cables you need. Has more customization options down to the cable length, but custom length will probably increase the cost significantly.
This site also categorizes their cables by PSU brand, I've linked Seasonic. Not sure if there's actually a difference between the brands, though.
Replies: >>368 >>372
I did a quick search and it turns out PSU cables are definitely NOT universal or interchangeable. You'll probably fry your computer unless you make sure they're compatible with your PSU.
Replies: >>369
This. Modular cables are not a universal standard, different PSU brands and sometimes even different models from the same brand (especially if they were manufactured by different OEMs) can use different pinouts.

Unless the cable is confirmed to be compatible with your exact PSU model, you'll be playing russian roulette with your hardware.
Wow at those prices I could just buy a new psu with better cables for less money. My PSU is 7 years old now and a bit overkill so I guess I'll just replace it in three years when the warranty runs out and get one that comes with better cables.

Special meta thread on /tech/. Meta thread rules updated 11/26/2020 19:32 UTC

Regular /tech/ rules don't apply on this thread, instead custom rules apply:
0. All global rules apply: https://zzzchan.xyz/rules.html
1. This thread is for the meta discussion about /tech/. Meta discussion about imageboards are ok to discuss about.
2. Spam will be deleted on sight.

- Get new users that won't taint the board with filth (please do not advertise yet)
- Work more on the rules and posting guidelines
- Add more useful resources to the /tech/ Sticky, anons can suggest what to add to the sticky ITT. (will eventually be migrated to custom board pages when the feature is complete on JSchan).
- Add custom spoiler and file thumbnails (not possible as of now due to the security settings of this JSchan instance, uploading custom thumbnail assets will be possible later on)

No idea. Nothing may happen tomorrow but I'll either enable the captcha soon or just leave everything as is. 
The TPH and PPH triggers are low due to the current normal speed, so maybe this isn't necessary.
Maybe it isn't even necessary to announce about manually enabling captcha.

Yes. Wojacks, spurdos (literally a newfag meme) and pepes are shit-tier and low-effort. Before these "memes" there were more creative reaction pictures but nowadays newfags just recycle the same ~3 pictures. +see >>326

>You don't need to be specific down to explain what exact kinds of posts are allowed. Just say no cuckchan-tier posts, which covers many well known post traits and mannerisms.
>I suggest adding examples for SHITpost and (fun)shitpost in the rules.
imo, the rule no. 4 is fine as it is currently, but if there are problems with it, BO should provide like 2-3 examples.

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):

We talk all the time about our preferred operating systems, programs, and window managers, but how do you think software affects people beyond productivity? Can an operating system push people towards creativity or make them lazy? Can chat protocols or different kinds of message boards shape how people think and act? Does using a window manager or the raw virtual console benefit you as a person more than suffering through Gnome Shell? Or are all our software choices just personal tastes that don't affect anything?

>Maybe people would listen to you if you complained about something that wasn't so stupid
You're not even accepting the complaint as valid. I've been an "artist" since I was a kid and have been using graphics programs regularly my entire life, even my job is related to graphics, and I'm telling you that the ability to draw basic geometric shapes is essential to doing graphics work. Yet you keep insisting that noooo it's totally fine if you have to do some 4-step workaround process every time you want to draw a fucking rectangle. Why is so important that Gimp doesn't have a geometric shape drawing tool? It's possibly the absolutely simplest tool to implement, Gimp literally has 39 tools so it's not like they're afraid of clutter, they have like 6 fucking different brush tools and 7 selection tools. You even admit that Gimp has lots of problems but why is this particular problem so important to never fix? It's like you're offended at the mere suggestion that it's a problem and start barking about "l0l window$ n00bs gtf0", how can you expect to ever make software good this way?

Of course Linux and Gimp are full of problems, what did you expect me to do, list every single one of them in that sentence? I'd have needed to make several posts to fit them all in.

By prioritizing bigger problems first like Gimp's developers are finally doing. I'll take all of Gimp 2.99's refactoring, better support for color space (the biggest issue holding professionals back from using Gimp, not muh squares), and other improvements over a dinky square tool anyday.

Firstly a geometric shape tool is much more fundamental and important to much more people than some color spaces, secondly "professionals" aren't going to give a shit about Gimp for a long long time when they can just pay $40 to get Affinity Photo which does everything 50 times better, thirdly it would take a day or two to add a geometric shape tool to the program, and fourthly Krita, the program you're suggesting as an alternative is the apex example of completely fucked up priorities.

If you do end up doing something like that, definitely post it here. At the beginning of the thread, some jewtube video was posted where a guy uses a script he wrote that seems to do a lot of the work for you when setting it up. As for hosting, you could always e-beg your members for money to keep the server up and maybe clear out the mailboxes hosted on the server every few months (transparently of course, so people are prepared and can download their mail and save it locally). If it's kept small and the servers are cleaned out pretty often it should be quite cheap to host.

People don't know what goons are. The majority of the original cuckchan userbase were goons or at least enjoyed somethingawful's content. It was one of the biggest internet influencers until /b/ took it's still and unleashed it. Being an old Goon (the type who defined Eva for many years) isn't a bad thing. It's being a modern "goon" who are entirely pozzed which is. Their Eva clan is likely laundering money and other stuff, but so is every other large eva group.

Doing this I feel like your outgoing emails would get filtered by spam filters so often that it would be too unreliable to use. I've never tried it but that's what I heard from discussions on email in many places.

2.1.35* my bad
Replies: >>259
Why 2.1.35? 2.1.15 can be emerged without systemd and rust.
Replies: >>264
2.1.15 has an issue with audio playing that isn't rectified until I think 2.1.16. And systemd and rust is required after 2.1.16. And also a ton of gay ass extensions require more recent versions. But anything above 2.1.16 would be good for me because that audio bug is atrocious. I use void, for a while I've been running Arch in a VM just to use Anki, occasionally seeing if I can figure out how to compile a recent version without much knowledge.
What's your distro? I made a dependency tree for Anki and the offenders are, as you've guessed, QT5 packages. Namely, qt5-base and qt5-webengine. But that's because they've been compiled to work with your distro's init, i.e. they depend on systemdicked dbus, util-linux and p11-kit. Unless they snuck something in their Rust code as well, any non-systemD distro that ships their own qt5 meta package with necessary flags (or you compile your own if you're on Gentoo) should support Anki. If compiling is not your thing, there is, for example, Artix.
You could prepare a separate installation of whatever distribution of GNU/Linux you prefer in a virtual machine dedicated to this purpose specifically which will have systemd so you can run anki in that machine, if you do not want systemd to touch your actual machine.

I was looking through the video editing thread on /v/ and figured it would be appropriate to have something similar here now that /tech/ exists. Except I think it would be ideal if the focus was on free software solutions, and also encompassing a broader spectrum of content rather than just videos.

In this thread give tips and ask questions about image editing, video editing, encoding, and anything else you think might be relevant for creating content.

I have some txt files that i need to convert to mp4, any reliable program to do that?
How do you calculate estimated webm size, to help you pick bitrates without completely blind trial and error? I remember there was some method to do it.

>too many packets buffered for output stream 0:1, conversion failed!
On my first day too.
I don't know that much about ffmpeg and conversion, but the only format that is reliably calculated is constant bitrate. As simple as taking the bitrate and multiplying it by seconds, just keep in mind that it's measured in bits. However, some sources say that constant rate factor is better, since it gives a less blocky picture during sudden movements as opposed to CBR. With CRF, there is no size estimation per se, you just specify a desired size and 2-pass encoding picks a CRF value to match that. I've seen a manual method mentioned, where it takes 5-10% of overall frames in the video and does a one pass encode with the value you specified. It's supposed to be fast enough to estimate size and play around with the settings, but I have no idea if it works.
On a side note, does anybody have that ffmpeg image guide that circulated around boards for video posting?

This board desperately needs a CSS thread. Why the fuck have none of the retarded board owners given themselves custom spoilers? Why the hell do no boards have custom load bars? I had both of these on fatchan because a nice fellow made them for me when I requested it to Tom but Tom had better shit to do. As far as I can tell that's the only board on JSchan to have ever had custom spoilers or loadbars. What's your fucking excuse? Bunch of shitbird elitist faggots on this site can't even figure out custom spoilers. You're fucking plebs. Either kill yourselves or get in this thread and figure out how to do it for your boards on this site.

>What's the simplest way to work with Linux sound?
In practice? Just stick with ALSA plus JACK for DAWs and other audio work and run anything that requires PulseAudio through apulse. PulseAudio just adds another layer of mess above ALSA, aka more stuff that can break, and I've had more problems with it than ALSA on its own.
Your main alternatives are OSS4 and sndio. I have no idea if anyone uses OSS4 but it sounds cool even with the poor hardware and software support nowadays, while sndio is mostly used by OpenBSD users and Voidfags. There's also whatever the fuck PipeWire is, which is trying to replace PulseAudio, JACK, and some video stuff. I know jack shit about it, but it's by a Red Hat employee so there's a good chance it will be cancer.
>Discuss ways of improving the Linux audio mess
Maybe some OSS4 fags can chime in, but it sounds promising to me.

>If I install Gentoo 
On Gentoo you can just enable the alsa USE flag in your /etc/portage/make.conf and enable the relevant options for ALSA and the HD audio in Linux kernel config (i.e. after you run make menuconfig) The tl;dr for PukeAudio is that you enable the kernel options that the ALSA/PukeAudio gentoo wiki articles tell you to enable and just enable the pulseaudio USE flag globally in your /etc/portage/make.conf 


If anyone uses mpd + alsa, make sure to resample to 32bit with libsamplerate. Audible difference.
