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.

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.

Also, I'm pretty sure I've said this before, but I'll say it again:

Part of your job as a senior is to tell your juniors about your fuckups. The embarrassing cringe reckless and lazy bullshit that you did when you were new, and the various times you brought down Prod. We ALL did it sometime. And then tell them: the moment you realized you fucked up, I know, the impulse is to try and cover it up, but don't do it. Come to the seniors you trust, and they'll help you unfuck it, and fight management tooth and claw like mamma and pappa bears to defend you from any shitheads in management. Because that's what our seniors did to us.

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

Here's my previous analysis of the problem:

@aerique Mozilla is preparing for a world where the US government (rightly) forces them to do without 90+% of their revenue. Rather than getting disgusted at them, why don't we urge the EU to support them and even do something crazy like take seats on their board or something? Could happen... maybe? Mozilla and this fork you want to make will die without support.

[oss-security] CVE-2025-48734: Apache Commons BeanUtils: PropertyUtilsBean does not suppresses an enum's declaredClass property by default

I wonder if the now restricted behavior is useful for #deserialization gadgets (I couldn't find references to declaredClass abuse, but haven't finished my coffee yet either...)?

I think "GCI" is a typo in the message (CGIServlet.java is patched), although found the same typo elsewhere in the documentation...

@keenancrane I wanted to mention those piggies, glad this design was not lost in time (had think really hard where I saw a similar concept, and it was about 25 years ago) :)
