#NoCVE

I always learn something new from @tomasp . This time, it was the existence of this book.

Can you write a whole book about a program? About a *1-line program*?

Turns out you can, and it is totally worth reading:

I can't praise this enough.

Re: NetLock distrust, this ticket is a good starting point to figure out what exactly the compliance issues were:

https://bugzilla.mozilla.org/show_bug.cgi?id=1904041

It's not a nice read with comments like "was comment 20 AI generated?"...

I have no idea why this works now and why it didn't work before...

Praise be the Omnissiah!

Google Chrome is removing Hungarian CA NetLock from its trust store:

https://security.googleblog.com/2025/05/sustaining-digital-certificate-security-chrome-root-store-changes.html

Stated reason: "a pattern of compliance failures, unmet improvement commitments, and the absence of tangible, measurable progress in response to publicly disclosed incident reports"

I've personally ran into revoked NetLock certs during the past months, the reason for revocation was unclear ("administrative").

NetLock was compromised previously as part of the Stuxnet/Duqu campaign:

I don't want to log in with a fucking Microsoft account.

I want to use my fucking serial port.

Data from the domain DNS shows that many European public services rely on proprietary cloud services: https://jurgen.gaeremyn.be/2025/03/08/european-critical-dependencies/

"Querying mail-servers teaches that in some countries, over 70% of all public services rely on this American provider."

Last week, #Microsoft allegedly decided to cancel MS365 services of Chinese universities with a notice of about one week: https://www.scmp.com/tech/tech-war/article/3305889/microsoft-abruptly-cuts-services-chinese-university-genomics-firm

Has anyone set up kernel debugging with a Windows 11 target with Proxmox (QEMU-KVM)?

This only works with Win10, Win11 doesn't boot for me:

Serial would also be an option if I could make them recognized by guests:

#GameHacking is really something else!

npm is getting trusted publishing soon!

https://github.com/orgs/community/discussions/161015

helping build and design the original version of trusted publishing for PyPI is easily in the top 3 moments of my career so far -- it's really amazing to see it get adopted by RubyGems, Rust (in progress), and now the JS ecosystem.

Had to make a proper GIF of this

Blasting Past iOS 18

Hot take: ISO standards do not meaningfully matter to me, because an extremely impoverished, unbanked person cannot freely access their contents from a smartphone or library computer.

Therefore, I go out of my way to avoid referring to them or relying on them in anyway.

Edge group policy ADMX is truly a masterpiece of bad-faith fuckery even by Microsoft standards: misleading, obfuscation, omission, outright lying.

Top 3 favorites so far:
1. Setting to disable the ChatGPT sidebar is called "Show Hubs Sidebar". Obviously, it is not under the "Generational AI" subfolder.
2. There are a number of "AI assistance" settings tucked under Settings > Languages in the UI. "Collaborate with Copilot" doesn't have a GPO item (forum answer from MS droid suggests that someone "forgot" it).
3. Three separate settings to prevent Edge from running in the background and "preloading" things, in three different folders.

It seems #IBMi ACS users keep strugling with Win11 hardenings:
