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?

Hyper-V from Windows 11 version 22H2/23H2 works without (and does not use) VHE

From version 24H2 onwards VHE is mandatory. Those releases also have ARMv8.1-A atomics and RCpc from ARMv8.3-A as required.

I love this so much, this is literally the physical form of a workaround that's grown to meet enterprise demands.

This is literally, physically, what developers mean when they talk about "tech debt".

Have a great weekend and enjoy some tunes:

I will stream in 8h about the basics of the PDF format, teaching how to make a basic PDF from scratch.

This is an easy-level introduction to the PDF [portable document format], aimed at all audiences: infosec, but also digipres, DFIR, and others.

This will not cover complex cases, polyglots, abuses or exploit.
That will come next but this stream is the start on the topic.
The stream will be recorded and available publicly.

Let’s try something new in 2025…
This saturday at 8pm CET, I'll stream about crafting a valid PDF file from scratch.
We’ll see how it goes!
