Time for a pointless nitpick on emergency exit signs! heckmeck.de/blog/nerdy-n...

phone recording of the @evoke.eu drone compo, featuring Swizzle from Shaderland :> my entry runs from 3:50 to 6:00 (starting with the trans flag of course ;p) look out for the higher quality official recording later! ^^ www.youtube.com/watch?v=_8EV...

Even if it has gone downhill for a while now, still a bit sad to see Reddit become completely unusable. There’s gold in so many old posts! How long before old.reddit.com is gone for good?

Out now! Download for free at worm.net Thanks to @stinkyox.bsky.social for letting us do a Llamasoft level. It’s been an honour, and my favourite level in the game!

AI subordination that I can get behind! Prompt: Make me look twenty years younger and likeable, but not so much as to highlight what a pathetic, vain mortal hides beneath my human flesh AI: Hehe… I mean: Sure thing, boss, here you go!

256 bytes is enough for everyone? Naww. But it might be enough to get a stupid idea out of your system. 🙂 heckmeck.de/demoscene/fi... #amiga #demoscene

CATALOG.EXE by Hackers is the perfect demo to help me test new Coppenheimer visualization ideas. And motivating, cause it's so awesome! www.pouet.net/prod.php?whi... coppenheimer.heckmeck.de (old version, planning a public beta of the rewrite)

Richard Dawkins could have had his “Claudia” epiphany in 1987 already, just with a gal called “Amiga” instead…

Found a pouët pig in the attic. A sign to release something again, soon! #demoscene #pouet

Cookin’ up Coppenheimer ideas: Displaying all memory words as RGB values adds a new layer of interesting! 🙂 Lookup tables suddenly become more observable, too

What a weird coincidence heckmeck.de/blog/cat-con...

The new iridescent window films remind me: I should watch “Annihilation” again…

Thirty years later I’m convinced: Flicker fixers are great! heckmeck.de/blog/flicker... #amiga #retro #rustyscrewdriver

calling it now

I get my news from a reliable source

I look at #Amiga "Cecconoid" published in 2024 by Thalamus. It uses a dual playfield mode, with CPU updating particles, the blitter modifies particle code, and hardware sprite multiplex with the copper. youtu.be/7OVBSs_Rl60

Valentine’s Day, isn’t that cheesy? Well, yes… 🐭❤️🧀 Yle Teksti V-Day Pixel Festival yle.fi/aihe/tekstit...

Poking fun at “Whoah, that LLM trained on natural language talks like a person!” is nice and all, but that meme could me more niche and retro! 😅 #sca #amiga

Sunday is Superball time – can’t wait! 🍿🤩 www.youtube.com/watch?v=Sy_S... #retro #amiga #ohwieschade

Snow + VR = 🙂 (why is there no emoji dorky-smiling-face-with-three-teeth?) heckmeck.de/blog/augment...

Some late-night workout with myself… Now it works on my own Amiga 500, too! heckmeck.de/demoscene/ne...

Sign-up and first information are now live! Save the date and start working on your productions! 2026.revision-party.net

Why are there so few snow flakes in the mouse pointer archive? You can draw one yourself with the editor (hint hint), but I have a hunch that there are many disks I still need to dig out… Time to take a closer look at .lha, .adz, and .rar files 🤔

The new project is nearly ready, but it doesn’t scale down nicely on the 1st gen iPhone SE. 😢 That’s a no-go. That device is barely ten years old! (Which is, by chance, the very thing sane people would say to dismiss the issue… 😅)

Results of the Vintage Computing Christmas Challenge 2025. Includes all almost 200 size-coding entries plus 18 wild entries. Just in case you missed it! YouTube: youtu.be/9aazdLrXah8 #sizecoding #vintage #retro #vccc2025 #BASIC #assembler #6502 #z80 #advent #apl #MerryChristmas

In true Vintage Christmas spirit: git commit -m "2 bytes saved, fuck yeah" 🤓 Looking forward to all the results on Sunday (see logiker.com/Vintage-Comp...) – much love and best wishes to @logiker.bsky.social for all the work!

It’s the season… to tune in on Finland’s Yle Teksti-TV! :) yle.fi/aihe/tekstit...

Prototypin’ for Christmas 🤔 #vccc2025

Handling strings and blobs in the browser is hard – you don’t only need JavaScript, but also *checks notes* Go, SCSS, C#, VBnet, and… Delphi! 🤓

Ooooh! There it is! Twinkle, twinkle, little… retro sizecoding Christmas star! :)

Amiga mouse pointers are weird. Did you know that you can set the hot spot way outside of the actual cursor? heckmeck.de/blog/the-imp...

Yes, it’s that time of the year again… 😊 heckmeck.de/demoscene/ge...

Still time to make us some festive #TeletextArt, if you want to be featured on Finnish television. 😎 Deadline is shortly before the final week in November. #ceefax #PixelArt #1bit #VideoText #Teletext

Working on an archive of all (*) Amiga mouse pointers. Back in the day, hand cursors were really popular! (*all = 70k disks so far, 27k custom preferences, 3k distinct pointer shapes and colors)

Seeing the actual, physical Amiga prototype board at #Amiga40 sure was nice! If you squint hard, you can make out shadows of the Boing demo running in the wirings… 🧐

Obsessive Star Trek thought: If I crash into this thing now, the Edo will demand my execution

Cooking up a lil’ Mate wall simulator to distract myself from other ambitious ideas for @deadline-berlin.bsky.social this weekend or just because I love writing tools? 😅 www.youtube.com/watch?v=J-nw...

I wish the nerds would have put a kill switch into all their inventions. “Oh, so you hate science and want to use the internet to destroy humanity? Not with our tech! You’re free to build a bible-based smartphone for yor christian-nationalist cult, though.”

Age verification check: Learned HTML on the Commodore Amiga by looking at page sources, with a dial-up connection that went through a special Datex-J (ex-Bildschirmtext) page that acted as an internet gateway. But that was already the modern days, with a 68030 CPU at 50 MHz and 6 MB of RAM.

So, the iPhone has genlock support now? Pfft… 1985 called! #amiga #appleevent
