@UNL999 @davidllada @Kasparov63 There‘s more: - seven white pieces on the first row, three more elsewhere on the board, and two more of the board 😳 - similar for black - I skip the details 😉 - what piece exactly is the white one in front of the chess clock? But the idea (Garry vs Garry) is admittedly great…

"Club de Ajedrez Peón Fénix" posted on Facebook this AI picture featuring @Kasparov63 that is pretty decent; one of the few artificial images about chess that I truly liked. It still shows a 5x5 board in the background, but we are getting there... 🙂

@ChessJoscho No it’s not. The code it teaches is shit and full of vulnerabilities. Nobody should learn from it, it’s out of date.

@Math_files Margaret Hamilton is also one of the few who got their own official Lego mini figure…

One of the most astonishing facts about the Apollo 11 Moon Landing is how little computing power was available. The onboard computer had only about 72 kilobytes of memory. In comparison, a modern 64 GB smartphone has more than a million times that capacity. This is why a famous photo of Margaret Hamilton standing next to stacks of printed code has become so iconic. She and her team at NASA wrote the software for the mission by hand and helped establish the field now known as software engineering. Hamilton led the team that built the flight software, laying the foundation for future space missions. Her work proved critical during the landing. Just three minutes before touchdown, the computer triggered the “1202 alarm,” signaling an overload. The mission was close to being aborted, which could have allowed the Soviet Union to reach the Moon first. However, the system had been designed to prioritize essential tasks and ignore less important ones. Thanks to this, the landing was able to continue safely. Reflecting on the moment, Hamilton later said they had no choice but to find a solution, and they did. Remarkably, she was only 25 years old at the time.

@MartinHusler @straceX Which „details“ of the ++ operator..? If you talk about the postfix variant incrementing after evaluation I would rather call that „purpose“.

@straceX Absolutely hideous. Assignments in a place where a condition should be. Relies on the details of the "++" operator which you should never do. A security threat on top because it doesn't care if one of the input memory areas is too small.

The classic strcpy implementation from K&R. Still one of the most quietly beautiful loops in C.

@igor_os777 It probably helped that they were familiar with the Unix FS (formerly known as Berkeley Fast FS, created in 1984) and only needed to decide on what to change from it. So some credit may be due to Marshall Kirk McKusick, Bill Joy, and their friends.

Linux filesystems weren’t always designed with sober clarity. Legend holds that ext2, once Linux’s dominant filesystem, was sketched out during a particularly heavy drinking session at a local pub in France by developer Rémy Card and friends. A beer-soaked napkin held the initial design specs, hashing out block allocation strategies between rounds of cheap Bordeaux and Cognac. Remarkably, ext2 functioned reliably for decades, serving millions of sober (and hungover) sysadmins worldwide. So next time you fsck your drive, offer a respectful toast: it turns out alcohol-fueled engineering sessions occasionally yield surprisingly robust designs.

@igor_os777 If you replaced COMMAND.COM with 4DOS you had no issue in MS-DOS: Both slashes and backslashes worked on the command line.

Igor Os@igor_os777·
Ever wondered why Windows uses backslashes (\) while Unix stubbornly sticks to forward slashes (/)? Blame IBM and Microsoft’s shortsightedness in DOS. Unix pioneered forward-slash file separation, a sensible design choice adopted in URLs. When MS-DOS added directories, forward slashes already had another job—command-line options. In a panicked rush, Gates and company arbitrarily chose backslashes. Cue decades of pain for generations of IT admins juggling both OSes. One tiny decision, forever cursing humanity with confusing slashes, awkward escapes, and decades of ranting from frustrated Unix beards. You can practically hear Unix devs laughing all the way from Bell Labs.

@brynden_rioss @stats_feed I strongly disagree. The 1984/85 match was NOT extraordinarily decisive. 23 (in words: twenty-three) title matches out of 49 total in history ended with a margin of more than two points (source: en.wikipedia.org/wiki/List_of_W…, only counting matches after 1886).
