This is what you get when you combine two of my passions, namely Italo Disco and the Commodore 64.

AUX0002: I Adore Commodore


Italian promotion video for the Commodore 64 from 1984.

Music: Solar Fox from the LP I Adore Commodore

Music by Marcello Giombini and Dino Siani.

Shamelessly copied from youtube.

So, Zig, the programming language. Are there any GUI libraries that actually work for it? I've tried ZIGUI and Cape but both seem to have gone without any commits for several months and the basic 'getting started' examples fail to compile (both with my distro's version of Zig as well as the latest manual download).

So, before I move on to test a third one (qt6 for zig), any Zig gurus out there who can recommend something? It's my first Zig project.

So, I decided that like any self-respecting, professional and absolutely not amateur retro computing vlogger I needed a second channel. I posted a first quick video there, measuring some basic waveforms coming out of the Covox I built recently and see how well they approximate the theoretical waveform.

Of course, having done this, I now feel the need to measure the same waveforms as reproduced by a proper sound card... I somewhat suspect that even modern hardware won't be able to generate a sharp square wave or sawtooth (although it'll probably be a lot sharper than the one from the Covox).

SR-2604: Installing FreeDOS and Building a Sound Card


Installing FreeDOS from floppies maybe wasn't the best of ideas, but we get there in the end. And what do we do when we have a DOS machine at our hands? That's right, we play some modules! But without a sound card that might be a bit complicated. So we have to build a sound card first. No biggie, and the reward is worth it, as we get to listen to an excellent module at the end.

I'm going to say something that's been festering in my mind for a while now. In my two decades of practice in information security, I have yet to see responsible disclosure result in measurably better security posture.

Code quality hasn't improved, patch management hasn't improved, minimum viable product hasn't improved, automated security updates, especially for IoT devices... [sup][sup]Jesus[/sup][/sup] [sup][sup]Fucking[/sup][/sup] [sup][sup]Christ[/sup][/sup] haven't improved. The cost of failure for organizations losing your data due to gross negligence has in no way improved, why should responsibility be the domain of the security researcher when nobody else is willing to share in that responsibility?

I'm half-tempted to say if you have 0-days you might as well get paid for them than be responsible. Because even with a tilted playing field, nothing has measurably improved since I've been here and I would argue with "vibe coding" and the tech industry's view of "Let the AI handle it" that software quality is the worst it has been since the 90s. I lived through windows millennium edition. I've seen shit you wouldn't believe.

"Hardware's fucked because we can't buy any, software is fucked because the LLMs trained by reddit and stack overflow are in charge now. You might as well fucking guess at this point."

Is what I said right? am I a fucking loon for having said it? I don't care. I haven't seen any improvements over the past 20 years I've been here and I'm fresh out of fucks to give when so-called professionals telling me that the way we've been doing things for so long, which has produced nothing positive so far as I have seen, should be maintained, stop questioning it.

nobody is held liable when breaches occur and your PII gets stolen for the fifth time in a single year.

And then we read the inevitable report that it was a third-party managed system that was 6 months behind in patches that got popped. Or it was a risk assessment result that they said "they would get to that eventually" and never did.

You start throwing executives in cuffs for failing to do their duty and sure as shit things would start changing.

Fi 🏳️‍⚧️

At this point, given the LLM situation, I don't think there's much value in coordinated disclosure.

But from a different angle.

'cuz given Anthropic and other LLM hawkers' attitudes, plus the way in which LLM spam has basically killed off the bug bounty platforms' usefulness?

given how security departments are being gutted in favor of LLM-driven shit?

given how engaging with the companies is going to entail arguing with their pre-primed-as-defensive LLM instances?

There's no way to approach this with a healthy state of mind; all the avenues that we've worked to implement for the past couple decades have been systemically dismantled.

So fuck it. Do whatever.

This right here, actually, is the thing that really pisses me off. Having everybody on a system where one set of 9 numbers that is effectively (1) immutable and (2) 100% dictates your financial life so therefore (3) must be kept secret, and yet nothing serious happens to anyone who is trusted to safeguard this information and completely fails in their duty to do so. I get shit happens but when the consequences are that dire for those harmed, maybe the consequences should also be dire for those that allowed and even arguably facilitated that harm after a certain point of negligence?

And then more and more businesses start to treat it as a requirement for doing business while *still* failing to secure it in any meaningful, reasonable way. It's fuckin' disgusting. The credit reporting bureaus themselves should have lost all credibility themselves the first ***Two*** fucking times.

which is most likely ?

  1. you are the only person on the planet to have ever seen this vuln. after fighting the corpo's reporting system for a week, you finally manage to get the report in. the company gives you its thanks, and months later, you get a check for $2.53
  2. the nsa is using this vuln, discovers that it's being patched, and moves on to other vulns
  3. as 2) above except is told it's being patched

Friends, comrades! Broad solidarity and international grassroots organizing be with ye on this auspicious International Day of Workers' Struggle.

We ourselves are the ones we've been waiting for. No one "runs" the world, there's no one who will swoop in and save you. We ourselves are the ones who recreate the society we live in, each and every day. As such,

I urge you; take responsibility for your agency in this world we share, and act like you have the power you actually have. Nurture kindness, respect for yourself and for others. Get to know your neighbours. Stand up for yourself, for your fellow humans, for other animals, for nature. Build networks of resistance. Solidarity and collective direct action are our strongest tools.

No one is free until everyone is free.

Hi folks; this is something I've been hesitant to post about since it's a very sensitive topic for me, but:

I'm moving out of the US later this year, and unfortunately for legal reasons I'll be unable to take my dog with me. All the rehoming services I've contacted are unable to take her in, so, I've made a little page about adopting her.

hi, i'm Nicoleta - never used a microblogging platform so this is all new to me :)

i love:
* computers - but the hacker culture / free software / sustainable tech parts, not the hypergrowth dark pattern stuff that plagues our existence nowadays
* writing, which i should do more of, over at nicoleta.bearblog.dev
* art & creative expression
* music, esp. electronic
* rhythm games
* dancing, i dance lindy hop!

i'm looking for a community of like-minded people, who feel the same about tech, which is why i joined here :)

if you're local (from Bucharest/Romania), let's get connected, and form a local group for FOSS enthusiasts/hackers/tinkerers!

see you in the cyberspace :)

Dead tired now, this forest dweller isn't used to city life anymore and parsing Norwegian took some energy too. Even visited the local hackerspace, hackeriet, played some more with meshtastic and shot some video for my peertube channel. Busy day.

Seeking a decentralized "Smolnet" for legacy hardware! 📟

I love the simplicity of Gemini, Nex, and Gopher, but I’m also drawn to P2P protocols like IPFS & Freenet. I want to combine these for machines with <100MB RAM (Nokia Symbian, WinXP) and unstable connections. Is there anything out there bridging these philosophies?

1/3 This is about a core philosophy: if a device still works, you have the right to keep using it.

Forcing people to buy new hardware just because the "ecosystem" moved on creates e-waste and deepens poverty. Everyone deserves access to info and leisure without being pushed into constant, unnecessary upgrades. 🌍💻

2/3 For limited devices, we need a modular, KISS approach—no heavy monoliths!

🛠️ Transport: Decoupled (P2P, Radio, BT)
🔐 Crypto: Optional local decryption
📄 UI: Simple text-first viewer (Nex/Gopher style)

You just download the raw text/capsule, decrypt if needed, and view. That's enough for the basics.

Linux installationsträff i Bagarmossen


 24 maj 2026 11:15:00 CEST - GMT+2 - Bagarmossen folketshus, 128 45, Stockholm, Sverige

Linux installationsträff i Bagarmossen
Sun 11:15 AM - 2:15 PM Europe/Stockholm

Microsoft slutade supporta Windows 10 i slutet av förra året, och många känner sig tvingade att köpa en helt ny dator om deras nuvarande inte klarar av att uppgradera till Windows 11. Vilket enormt slöseri!

Men det finns en billigare och bättre lösning: Byt till det fria och öppna operativsystemet Linux! På så sätt kan du ge även en äldre dator nytt liv.

Kamratdataföreningen Konstellationen och Uppsala Linux User Group bjuder nu in till en installationsträff i Bagarmossens Folkets Hus. Vi visar olika varianter av Linux, du kan provköra Linux och du kan få hjälp med att installera. Ta med dig din dator, och gärna också en USB-sticka eller annan lagringsmedia.

Varmt välkommen!

Well, the current situation also has trains that can be later / earlier than needed, so I guess they sometimes will have to wait until the can enter the central corridor? If there's trains every minute, there is no guarantee that when a train arrives from, say, Hasle and wants to enter the loop at Carl Berners plass, that a slot is available for that train.

Anyway, I'd like to play with this system in a simulator sometime. I don't suppose there's a track layout available somewhere? Are all the stations 2-platform or are there stations where lines join that have more?
