In France, a Platonic friendship with a woman is considered a far graver form of infidelity than a sexual affair because the French are a civilized people who understand that Platonic love is a higher form of love than mere worship of the flesh

Emmanuel Macron reportedly maintained a platonic relationship with Iranian actress Golshifteh Farahani for several months, which allegedly led to Brigitte Macron slapping him.

Just found out an active File Pilot community member @thomasklemenc made a task manager inspired by it! Handmade from scratch, C++, win32, D3D custom renderer, 1.55 MB. More of this in my feed, less AI slopware.

GitLab announced a layoff today. Please take this seriously. There will be many, many more. Your assignment is clear: Get skilled with agents and practice shipping to prod. It doesn't matter if you're HR, eng, infra, customer success, admin, ops, sales, whatever. As a Founder/CEO, I can tell you that I won't be hiring any employees who aren't really skilled with agents and able to ship to prod. I'm not alone in this. There is no 'engineering' org in the future.

@brockpierson also please note Microsoft used special formatted floppies for their distrib. They can fit 1.64MiB per floppy instead of classical 1.44MiB ( it helped a bit reducing amount of floppies :) )

@s4schoener Right,but isn't that just because the timer interrupt fires during the memory stall itself (load instruction), and the "return EIP" address just points on the following instruction (jz). It's like when enabling "trace" interrupt, the EPI always points the following instruction

One of my favorite features of my profiler ktp is that it can show you *why* something is slow. For example, in the picture below it shows you that the hotspot that is responsible for 45% of the time is a memory stall: the memory access is missing cache and we have to wait. At first glance, this might be surprising: why do all of the samples fall on a conditional jump!? ("jz") Because that's where we actually stall! The line before that is accessing hot_entry->valid. This memory access takes long, but it is only the jump that needs the result of that comparison. Note that this is not an issue of branch misprediction: in practice, these entries are almost all valid (branch is almost never taken). We predict the branch correctly and continue executing speculatively, but at some point we have to wait for that jump to actually retire, and that depends on the memory access.

@Adriksh agree but still a lot of very annoying things. Like when you load several wavs, if you click on "solo", then "solo" on another one, the first isn't "un-solo". Very annoying

Audacity’s UI still looks like it’s stuck in 2004, yet it opens instantly, edits audio without subscriptions or sign-ups, runs on almost anything, and somehow feels less bloated than most modern software.

J’ai acheté Une brève histoire de l’avenir de Jacques Attali en 2006. Je l’avais trouvé brillant. Vingt ans plus tard, après une dizaine de déménagements et de pays, le livre a jauni, mais il a survécu. Je l’ai donc relu d’une traite aujourd’hui. Attali avait plutôt bien vu Internet, le travail nomade, les loisirs et cette tyrannie moderne de l’image de soi sur les réseaux sociaux. Mais sur la Chine, l’Iran, la Russie, le Nigeria, l’Afrique, l’Europe, la géopolitique en général, il est passé largement à côté. Et sa Corée du Sud appelée à devenir la première puissance asiatique mérite un sourire poli. En réalité, il écrivait dans l’ivresse d’une époque convaincue que l’avenir serait forcément occidental, libéral, démocratique, ou ne serait pas. Comme souvent, les croyances du moment se déguisent en prospective. Je dois d’ailleurs dire souvent, les auteurs de science-fiction voient plus juste que les professionnels du futur. PS : il n’a pas non plus vu venir la révolution IA. Ce n’est pas un détail : c’est probablement la plus grande rupture technologique de notre temps.

I take no pleasure in reinventing the wheel, but was sufficiently frustrated that Windows Magnifier was so slow to open/close and had usability issues (tried several other ones which had issues too), so I wrote my own in-app magnifier to inspect rendering issues.

I'm going to give you a computer science problem, covered by a software patent (US 4,197,590). Let's see if it's "obvious" to experts in the field. You're on a monochrome display. You want to draw a PLUS sign cursor, like in a paint program, leaving the pixel in the middle unchanged. How do you draw the vertical and horizontal lines without stomping on the center pixel? Do you save the center and put it back later? Or what's your solution? No sprites, of course, all done via Get/SetPixel(x,y) only. Assume something like bool GetPixel(uint x, uint y); void SetPixel(uint x, uint y, bool b);

@TheRetroHQ @DefenceForceOrg really depends on compiler. Modern x64 compilers generate quite efficient and readable code imho. 68k compilers are pretty bad, like really bad. (because of their age I guess). I like using godbolt.org quite often to compare compilers generated code

@DefenceForceOrg I just had the opposite experience and was shocked how poor the optimised ARM code was from GCC. 😞 And to be honest code doesn’t have to be unreadable to be fast! Compilers just do make unreadable code full stop.

"the assembly that's produced by compilers is so optimized and confusing that you can't even understand it" The last time I checked, x86 compilers could write much better code than I could, but it's still quite readable because optimized code is actually very compact.
Darren Shepherd@ibuildthecloud

We're definitely going to get to the point where handwriting code doesn't make sense. Similar to handwriting assembly doesn't make sense. But the analogy breaks down. Developers don't really know assembly and they can't really review assembly. On top of it, the assembly that's produced by compilers is so optimized and confusing that you can't even understand it. For AI the code that's being produced, the developer needs to understand it could have written it themselves but it's just not as efficient or safe to do so. AI is not a new abstraction layer. It is a tool to create something you understand. We still need people to understand the mechanics of coding. We still need people to learn these skills and these are important skills. And even with the power of AI, you can't get away with not knowing these skills if you want to be effective. As always, there'll be people who try to take shortcuts and they'll get short-term gains and then it will fall apart.

I just released LSP v1.30, which adds an ADPCM compression option to drastically reduce MOD file size in executables or on disk. As a bonus, no changes to your workflow are required. More details are available in the GitHub README. #amiga #demoscene github.com/arnaud-carre/L…

@CameleonTH looks nice. But Amiga is 7Mhz computer :) LSP ADPCM decoder is just 2 instructions per output sample. QOA seems way more heavy on CPU

@leonard_coder I'm curious, but have you considered using QOA format to slightly reduce the filesize without realy increasing the decoding complexity ? I'm using it in my engine to compress all the audio samples.
