#genuary5 prompt: Isometric art.

It's game of life. History goes down. I've seen a visualization like this last year and wanted to recreate it.

I have this favorite story about "the first 3D shopping mall" on the Hungarian Internet: it was of course a massive failure, because the minds behind it didn't realize that people are not going to the mall to use escalators (which was precisely modeled in VRML along with corridors, benches, etc).

I think the recent enthusiasm about GenAI-driven voice/video recognition is similar in this aspect: in many cases people would prefer a system *not* involving human(-like) interaction (or using an escalator), it's just we currently don't have better solutions for many tasks. Assuming a speech/video interface is always better than e.g. a bar code reader results in faster horses, not cars.

#GrapheneOS appears to be standing up to UK forensics, in this painful and "unprecedented" case which could see a UK journalist go to jail for not relinquishing the passphrase to his devices. Not only is withholding his basic human right, but he does it to protect his sources, and as ratified in the European Court of Human Rights.

The last couple of days I worked with @tmr232 to bring binaries to his @cfgbot.

Here's my script to export CFG's in DOT and JSON formats from #Ghidra:

I also exported the latest Microsoft Defender and openssl binaries:

Arrrgh does anyone have a recommendation for a hugo theme that is very very simple (no sass or npm etc), text-centric, responsive, and accessible? I am trying to move off Wordpress for this site:

Following my live stream yesterday to introduce the basics of the PDF file format, I will stream live in 7 hours on the risks of information leaks in PDF document, based on in-the-wild examples and hand-written PoCs.
The pace was nice and chill - see you there! https://www.youtube.com/live/hncHOnppwl8?si=yfWEeTbiXgoHbp-D

Just learned that Amit Yoran has passed.
He was a friend, and a long-time supporter of @SecurityBSidesGlobal from the early days of NetWitness through his leadership at Tenable.
Fuckity fuck fuck, would y'all stop dying and shit? Please?

I still don't get GPU accelerated terminal emulators.

I just git added a directory of >100k files in a non-accelerated terminal and I didn't even notice the combined lag of terminal prints **and** git tree updates in the background. I only noticed the change was this large because GitHub complained!

and i dont even drink anymore!

Good news: I'm drinking Port wine
Bad news: Haven't reached the Ballmer Peak

I was forwarded this screenshot and it just is living rent free in my head right now.

As part of the 20th anniversary of the BBS Documentary's release, I've ripped the 3 DVDs that were included in the project and have them hosted at Internet Archive. These ISO files can be played in the VLC player like DVDs, and include all bonus features, subtitles, director's commentary, etc.

I read a paper book about a subject yesterday and it was ✨amazing✨ 10/10 would recommend trying books.

They look kinda like this emoji you might have seen: 📖

At no point did the book scold me because I have a whole-house ad blocker.

At no point did the book invite me to set up an account to continue reading.

At the end of the book, it simply ended, without immediately showing me additional, less relevant books.

Books. On paper! Who knew?
