It’s 49,781CE. Humanity has reached the stars and spread among galaxies. We’ve reined in physics and all of space, gravity, time, matter, and energy is ours. The great blooming accelerates.

And there’s still no way for two arbitrary devices to share files.

I feel like I know at least one person for each of these options...

A fake "reCaptcha" page with multiple options:

I'm not a robot

I'm not a robot MYSELF, but I'm not judging those who are... 

Define robot 

I'm not a robot, but I know you are, so this feels a bit hypocritical

I reject the binary assumptions underlying this statement 

I'm not a robot, but I'm willing to convert

Escape room: Bookstore. The doors are unlocked and accessible. The path is clear. There is absolutely nothing preventing you from leaving.

You have one hour.

@Vivaldi Ohh, those colored tab groups are just awesome! *chef's kiss*

(But then again, grumpy me also noticed that the annoying light-mode-website-preference-is-ignored regression is still present in 7.5.3735.41 ... :)

@gloriouscow Oh yes, absolutely! I used to do occasional homework in GeoWorks Ensemble 1.0, 2.0 and finally NewDeal Office 3.0 on a 286, from ca. 1993 until 2000. Super stable and fast compared to Windows. Good feature set. Excellent print quality even on modest 9-pin printers. Later, I used PostScript export to disk (which was, and still is, slightly broken in a very annoying way: you can't use any of the Base14 fonts) to print the results on one of those newfangled inkjet printers ;)

Livecoding meets AMIIIGAA! This year, we’re proudly presenting world‘s first Copper Showdown - and we want you to show us what you can do with it!

Brought to life by @mop Copper Showdown follows a well-established routine: You compete on stage against others (and the clock!), with a DJ providing the soundtrack to the battle. Once the clock runs out, our visitors get to vote and decide who will be our first Copper Champion! (Yes, there will be a shiny trophy🏆)

@PenguinToot @thomholwerda DOS didn't have anything that's even remotely like the Registry. It has been introduced in Windows 3.1 to store file type and OLE/COM associations.

And let's face it, every major OS stores at least some of its configuration in weird database-like structured files by now. Windows? Registry. macOS/iOS? XML .plist files everywhere. GNU/Linux? dconf (though the amount of infestation varies with the chosen desktop environment). Android? SQLite.

@gloriouscow More importantly, this was how HIMEM.SYS worked on 286s *all the time*. No switch to protected mode and complex keyboard controller or triple fault resets - no. LOADALL was the load-bearing part (pun intended).

Using Windows these days feels like I'm walking through a major airport. Its bright and glossy, there's ads everywhere, there's random noises and shit getting in your way, the signage is confusing and sometimes the pictorials make no sense, random announcements you can't understand, some of the design aesthetics are new, and some still stuck in the 00s.

focus stealing is basically malware

@pair12 @dalias Be careful: LZSS (Lempel-Ziv-Storer-Szymanski) is not the same as LZS (Lempel-Ziv-Stac), although the two are closely related, both being LZ77 derivatives.

An interesting observation regarding the PNGv3 specification that's making the tech news today: Chromium-based browsers seem to support that already! The demo page at svgees.us/blog/cICP.html has a PNG image using the Rec.2020 color primaries on it, and it signals that only with a cICP chunk (no iCCP!), and my browsers, both desktop and mobile, display it correctly.

@NohatCoder @lritter @rygorous Or when a character played by Dwayne Johnson is about to do something utterly stupid.

@foone See, orange color and a flag with 6 bands make things a bit more involved.
(Code optimized for easy customizability via the b$, f$ and i$ constants; colors on the last two lines must be identical and use the same background and foreground, for complex reasons.)

pride flag shown by an (emulated) ZX Spectrumsource code that produces the pride flag:
10 LET k=85: FOR i=0 TO 7: POKE i+USR "A",k: LET k=255-k: NEXT i
20 LET r$=CHR$ (144): LET r$=r$+r$: LET r$=r$+r$+r$+r$: LET r$=r$+r$+r$+r$
30 BORDER 0: CLS
40 LET f$="222222226666444411113333"
50 LET b$="222266666666444411113333"
60 LET i$="111111111111000011110000"
70 FOR i=1 TO 22: PRINT PAPER VAL b$(i); INK VAL f$(i); BRIGHT VAL i$(i);r$: NEXT i
80 LET d=8*VAL b$(i)+64*VAL i$(i)
90 FOR a=23232 TO 23295: POKE a,d: NEXT a
100 IF INKEY$="" THEN GO TO 100

@foone Like so?
(Mildly size-optimized; tape file is 169 bytes. Can be extended to other colors by changing the c$ constant, but orange would require dithering, which is a bit more work; also, it could be made nearly fullscreen, but that's quite a bit more complicated too.)

trans pride flag displayed by an (emulated) ZX Spectrumsource code that displays the trans pride flag:
10 BORDER 0: INK 0: PAPER 0: CLS
20 LET r$="    ": LET r$=r$+r$: LET r$=r$+r$+r$+r$
30 LET c$="55553333777733335555"
40 FOR i=1 TO 20: PAPER VAL c$(i): PRINT r$: NEXT i

@lritter Source? They played a "Rollt das Fass rein" / Baddadan crossover at their latest concert tour, but I'm not aware that they released that track in any form?

do I know anyone who has written a gcc or llvm backend for a new architecture (or a tutorial on how to do so) within the last several years?

I would like to compile C code into assembly for a toy architecture. I don't really care which toolchain I use, this is very results focused.

unfortunately the only tutorials I can find were written long enough ago that significant changes have been made to the toolchain codebase and even with educated guesses I'm hitting roadblocks at the first step.

@0xabad1dea the problem with latex jokes is that you have to say them twice so that the references make sense
