@benoit Did they at least give everyone one shot of the updated bivalent booster targeting the #Covid Omicron variants?

Now it can correct itself? I'm no longer so sure this isn't taking tips from humans. 😮

Good bot, DAN!

@john And here's the patch adding the new arithmetic simplification ahead of the GCC 12 release:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94589

@john Ok, here's the solution: it's due to C++20 defining only the new operator<=>() on chrono types, combined with a missed optimization:

@Artisttomo I knew the meaning of 何か in expressions like 何かあった (something has happened), but 私なんかが勝てた was a bit confusing: "I... something... won"??

I also didn't quite understand why sometimes they'd use なんて and sometimes なんか 😅

This is a reduced testcase from a large codebase for 32-bit ARM microcontrollers.

Yesterday I noticed that GCC 12 generates the exact same code in C++17 and C++20 mode.

This morning, a GCC developer guessed the issue and pointed me at the fix that was merged two years ago.

I can't update my toolchain right now, but knowing what triggers the bug made it easy to come up with a workaround for GCC 10.

C++ compiler puzzle: can you guess why GCC 10.3 generates slightly worse code when switching from -std=c++17 to -std=c++20?

I heard なんか (nanka) and なんて (nante) countless times in #anime set in modern Japan.

I guessed from context that it's slang for something negative or annoying, but I wasn't sure about the meaning because there's no direct English translation. In fact, it's usually lost in subtitles.

@benoit Hopefully everyone will have 4 or 5 vaccinations by now...

@benoit Is it better than libvirt?

Yes, sounds good!

@benoit I use Atalassian's lousy products every day, and I detest them.

They also don't seem to give a shit:

#Neovim has more GUIs than I can count, but they're all at the demo / concept stage, and even those market as "active" aren't in fact very active:

Ah! finally got it to work! I just had to *downgrade* mesa to 22.3 and set RADV_PERFTEST=rt to enable VK_KHR_ray_tracing_pipeline.

@PeterCxy #linux #vulkan #gpu #raytracing

Is VK_KHR_ray_tracing_pipeline supposed to work in #amdgpu in Mesa 23?

On the RX 9700 XT, it hangs the GPU. The kernel reports dozens of "[gfxhub] page fault" from the rendering process. I tried with kernel 6.1 and drm-tip.

I'm testing with this demo:

@alrj You beat me on time, but see the rest of my monologue 🙂

I was forced to use Turbo Pascal in high school. I complained that it was an obsolete language, but my teacher insisted that it was good for me so I wouldn't learn bad habits from C... like early return, break, continue...

In formal circles, those constructs were accused of being "non-structured" control flow, so my teacher would argue that adding flags to abort loops was better style 🤦♂️

@srevinsaju #programming

Pascal had an explicit distinction: functions are procedures which return a result.

K&R C didn't bother with procedures: everything is a function, and if you omit return at the end, it will return garbage to the caller 😂

Later, ANSI C added the "void" type and (optional) function prototypes, making this footgun somewhat less dangerous.

Support for declaring and defining functions without a full prototype will be finally removed in C23:
