The annoying nerds who said you should install Linux, use decentralised social media, use Signal secure messenger were right.

Control of our own computing is a prerequisite for freedom.

The internet *is* real life.

This afternoon I wanted to show someone the moiré pattern you get if you draw lines on a pixel grid from a single origin point to every point on a line some distance away. Those were a favourite toy program on 8-bit micros.

[Edit, the next day: I forgot to mention the *main* point! The lines are drawn in XOR mode, so that each line is drawn by inverting its pixels rather than just setting them all to black, creating an interference pattern.]

I could surely have figured out how to draw this kind of thing in a modern graphics system, but I _knew_ I could remember how to do it on a #ZXSpectrum, so I just fired up FUSE and did it the way I’d have done it in the 1980s.

… I guess this is worth tagging #Genuary, in a retro-nostalgia sort of way?

Was ihr schon immer über die #eID wissen wolltet, aber nicht zu fragen getrautet.

Heute das Wichtigste zusammengefasst bei #DNIP von @revogt

Einige Antworten des Bundes sollten zu weiteren Fragen Anlass geben:

1️⃣ Wie meinen sie das mit «kein Backup»? (Redundante Speicherung *alleine* ist kein Backup.)

2️⃣ Wieso ist das Löschen der App automatisch eine «Ungültigerklärung» der eID? (Ist ja evt. nicht einmal eine Deaktivierung.)

Respect to Elisha Hollander (donno2048) for a 56-byte asm DOS snake game: https://github.com/donno2048/snake/ with extensive comments in the code, packable as a QR code. #demoscene #snake #asm

up-to 69 byte story here (2023):
https://dev.to/donno2048/the-journey-of-creating-the-smallest-snake-game-in-the-world-4ell
but since then improved by another 13 bytes, nice!

So let me get this straight: First, it was Elon. Now, it is Mark. Two guys are removing all moderation rules on social media. And are people asking another billionaire to build alternative social media? Do you even hear yourself? That is not going to fix anything. Maybe we should go back to the days of blogs, mailing lists, individual forums, and RSS feeds and end this madness of centralized social media apart from the federation. I’m just saying

RT bk2204:

This factorization of a 512-bit DKIM key is quite interesting and shows why small keys are a problem.

3072 bits is the appropriate minimum size for RSA keys these days, although some people try to get away with 2048-bit keys. I do still routinely see lots of 1024-bit keys for DKIM, though.

Idk who needs to hear this (actually I do: it’s the EU courts), but if my interaction with your website consists of reading text and nothing else, then there are no “required cookies”. You can fuck right off with that.

Here’s a quick piece I wrote up on how to understand DOGE as a very blatant attempt at procurement capture, a simple way of making government spending corrupt to benefit the tycoons. Please do pass it along & share any feedback! https://www.anildash.com/2025/01/04/DOGE-procurement-capture/
