As someone who has been programming since being a young teenager, things like this make me enormously sad.

If I was banned from being part of tech communities until the age of 16 or even 18 I would've never been able to learn all I did. I would've never been able to truly get into FOSS.

I would've never had a chance to become who I now am.

Age verification is literally killing the ability for kids and teens to excitedly participate and learn cool stuff and learn how to have digital agency.

This.

I grew up on forums like XDA developers and started posting there when I was like 11. It taught me English, taught me what software freedom is, got me to write my first few lines of code, share software with friends and like-minded people online, and made me who I am today.

We must fight to keep the communities that made us who we are. There is still a way forward.

We've Been Here Before: Decompilers, Fuzzers, and Now AI

https://www.clearseclabs.com/blog/weve-been-here-before-ai-vulnerability-research/

Remember the old 2600Hz thing and how much money it cost AT&T? In hindsight, it was so obviously dumb to put control signalling and user-data in the exact same channel. We'd learn from that, right? It's so obviously a terrible idea that can never work safely that we'd never do something that dumb again, right? RIGHT?!

Oh wait. That's pretty much standard operating procedure with AI agents. Just jam it all in the same context, what could possibly go wrong?! Surely it'll be OK this time, right?

Where do the people hang that read our hacks blog post and then went through all of the bugs that we opened up? Really eager for the deeper, informed takes now :) https://hacks.mozilla.org/2026/05/behind-the-scenes-hardening-firefox/

[RSS] Getting LLMs Drunk to Find Remote Linux Kernel OOB Writes (and More)

https://heyitsas.im/posts/drinking-llms/

“It looks like you’re building an off brand LEGO kit! Would you like help with that?”

here's a technical write-up i wrote on one of the kernel bugs we've found :)
https://bird.makeup/users/bynar_io/statuses/2052720419157782809

When we said that we found and fixed hundreds of bugs in Firefox using AI, people were skeptical and said: Where are the bugs?

Well, here they are. We are unhiding 12 security bugs that are representative of the issues we have found.

https://hacks.mozilla.org/2026/05/behind-the-scenes-hardening-firefox/.

Remember when we used to dial into the internet, and the machines would scream at us?

That was a warning right?

I'm a little concerned about the general tech attitude towards the Mozilla bug findings. Yes, I'm an AI hater, so add that to the biases, but that's not really the point here.

People seem excited about the fact that Mythos was used to find a bunch of security bugs in Firefox, which is cool:

https://hacks.mozilla.org/2026/05/behind-the-scenes-hardening-firefox/

However, the general attitude seems to be that devs can keep pushing for more new things because some AI system will catch the bugs for them. But to me, there should be more concern about how there were so many previously unknown unfixed bugs in Firefox to begin with. These findings should be a cause for concern and give pause to evaluate how so many security bugs make it to prod. And I'm not just talking about Firefox, everyone should be learning from each other in this space.

If nothing else, people celebrating the LLM-fueled bug findings should be recognizing just how much harm the whole Move Fast and Break Shit approach really creates rather than allowing the LLMs to be the excuse to move faster and break more shit.
