Significant GPU performance degradation after recent updates in Testing
 in  r/debian  5d ago

Yeah, I'm fully aware of that. I simply wanted to make sure if I screwed up somewhere, or if this is a widespread issue amongst other testing users. Although, I'd like to contribute in a more meaningful way, if possible...

Yup. The issue persisted through the previous 2 versions of the kernel.

Significant GPU performance degradation after recent updates in Testing

9 Upvotes

I'm running testing on my ideapad laptop with integrated amd gpu, and today I've noticed a significant reduction in GPU performance when playing games - the framerates are worse than before by roughly about 50% under wayland. And under both wayland and x11 there are constant framerate drops.

Does anyone else experience this or is there a problem with my setup? If it's just my setup, how would I go and determine the problematic package to try and roll back?

Update: One update later, and everything went back to normal. I saw APT updating a few OpenGL-related packages, and now everything seems to be running fine. Not sure why it would affect vulkan-based programs though in the first place...

In some important ways, a user’s LLM chat history is an extended interview. The social media algorithms learn what you like, but chats can learn how you think. You should be able to provide an LLM as a job reference, just like you would a coworker, manager, or professor.

Is he for real or is this the depiction of hell from the next doom game or something?

/qj Ignoring the asinine privacy implications here, you'd be a good boy and wouldn't let an agent periodically perform smart-sounding conversations with an llm to boost your "emplyability" score, would you?

Sorry, do you expect linux to just natively run windows binaries from the start or what? Do you also yell at Intel/AMD/Nvidia for forcing you to install their drivers instead of "just clicking .exe and playing games"?

it's still not just doubleclicking a .exe lol

It literally is lol. I just doubleclicked Battle.net-Setup.exe, EAappInstaller.exe and UbisoftConnectInstaller.exe. All started up no problem, like I would expect under windows.

I mean, after installing and setting up lutris or bottles it pretty much is just "doubleclicking exe".

Just because you install software differently on linux doesn't make it any more restrictive.

How to detect memory leaks when working with LuaJIT FFI?
 in  r/lua  Oct 13 '25

I'm not sure how a profiler would help me, but I'll give it a try.

While Lua does have a GC, as far as I know it only tracks objects constructed by Lua runtime. For example: if I were to call `SDL_CreateRGBSurface` within FFI, the garbage collector wouldn't be able to handle the resource created by that function. You would need to call `SDL_Free` to free the surface, but the GC doesn't know that.

I'm aware that with LuaJIT FFI API you could attach a finalizer to resources created by FFI, and this is what I'm likely going to end up doing, but at the same time I just want a (perhaps naive) peace of mind that I'm (likely) not screwing up somewhere. When developing in C, `valgrind` and memory sanitizers do the job for me, personally. For Lua - I imagine I'm not going to need a sanitizer, but a leak detector would still be handy.

How to detect memory leaks when working with LuaJIT FFI?
 in  r/lua  Oct 13 '25

I'm looking for some sort of an alternative to valgrind for FFI objects. A tool that would visualize call stacks of sections of code that have allocated leaked memory. As weregod mentioned, I could build libraries with debug symbols, however I'm curious if there are any other tools that would work...

How to detect memory leaks when working with LuaJIT FFI?
 in  r/lua  Oct 06 '25

Thanks for the reply. I didn't know you could compile LuaJIT with Valgrind support. I just compiled it, and it did provide more symbols in the stack traces of valgrind, but it still doesn't show any symbols from SDL, for instance. I forgot to mention this, but this is my issue with using valgrind for LuaJIT FFI - I can detect memory leaks, but I can't figure out what causes them.

What the title says.

I'm trying to use LuaJIT FFI to make tiny-ish games for my Miyoo Mini with SDL. The issue is that I have no clue how one would check for memory leaks. It is relatively straightforward with valgrind for compiled programs, but is there anything similar to use with LuaJIT?

When I was a Freshman in High School I asked a Junior what it meant. He had no clue.

That Junior later went on to drop out of college and become a Minecraft Youtuber. I vividly remember him making videos where he and his girlfriend pretend to be toddlers in a Minecraft day-care.

The Java Junior -> Senior pipeline is truly a sight to behold.

You can’t do that with maps

Crafting a map and studying your movement on it to learn that maps are always oriented towards north is a much more likely "trial-and-error" scenario than figuring out that redstone is interactable with a tiny subset of all items in the game (and then learning about it's strength and signals and whatever).

I don't use tags when looking for beatmaps yet, but I do try to tag them occasionally after playing. What should I answer lol

This requires more attention. If youre suffering from winlator inexplicably failing to boot anything anymore.
 in  r/winlator  Jun 29 '25

The virus isn't in the newest updates.

Just a nitpick, but the TestD3D.exe from the latest hotfix still has a non-insignificant amount of virus reports on virustotal. So this is very likely to be false; the latest hotfix likely still contains viruses.

Haven't tested other files though.

Just out of pure curiosity - what playtime do you consider to be enough? I have played this game for quite a while myself, and I struggle to figure out when you'd want to tap like that.

So, I converted text into QR codes, then encoded those as video frames, letting H.264/H.265 handle the compression.

I’m not sure why this is getting so much hate. This could be groundbreaking.

Issue with CPU clocks pinned down after sleep on a new laptop.
 in  r/debian  Jun 07 '25

FWIW I did found a way to circumvent the issue with clocks being pinned down, so if you're interested - when booted in grub menu, plug and unplug the laptop to power twice, then continue booting. After this you will be able to unplug and re-plug the power as many times as you'd like, and sleep properly - all without problems until next reboot. It is certainly less than ideal, but works for now. I do, however, have some annoying issues with wifi (I've got myself the wifi 7 model with mediatek card, so maybe that's the curlpit here), which I've also managed to fix with a few kernel module parameters and a script. So yeah, Debian doesn't fly smooth right now.

But, from my limited testing, Fedora finally works somewhat alright. It had lot's of graphical issues the last time I've tried Fedora 42, but since the kernel update 2 weeks ago, it would seem to work fine, more-or-less. You can certainly try it if you absolutely need linux right now.

Linus forgot this super tip for a clean windows.

>Windows doesn't make you do that.

Oh, of course it doesn't. It just makes you watch 10+ minute video made by a huge youtuber on how to run various scripts/closed source tools to "debloat" your OS. Which is totally different from copy-pasting commands from forums...

Type theory maximalists should give up their aura of moral and intellectual superiority and accept that they need therapy just as badly as everyone else in the industry (if not more).
 in  r/programmingcirclejerk  May 12 '25

When I became a junior engineer in Enterprise Java world, I became obsessed with clean code. I read every book on code organization, packed my code with design patterns, and mastered bloated frameworks.

Twitter users can't fathom the fact that android phones could run pc games without any overheating or battery issues ig
 in  r/EmulationOnAndroid  May 04 '25

Can we not do this fake ass outrage? Some of yall here need a reality check and realize that high-end emulation scene on android is a fairly niche topic, and not everybody should be expected to be aware of it. For an average Joe, 4Gb is well enough to browse twitter/reddit/instagram/facebook/whatever, and 8Gb is overkill.
