Gonna pin this tweet so later on when I can't remember what my pinned tweet is I will come find this tweet and applaud myself for my mediocre meta-humor

After nearly eight hours detained at the police station they have released nearly all of us.

I am part of this group being detained. All for supporting Palestinian farmers to harvest their fields

[jasper nathaniel @infinite_jaz]

At least 45 international activists, including Brad Lander—a proud liberal Zionist—were just rounded up by police at an olive harvest in Nehalin and put on a bus. Unclear if they’re under arrest, being deported, etc. (I’m reporting this secondhand from Taybeh, where another fascist crackdown just took place.)

@tweetelissa @bradlander I’m with Hannah now! She says hi!

[Dov Alperin @dovunderscore]

@TaliaRinger All of us out here appreciate it. I follow you for comp sci reasons and appreciate your calls for peace

I'm reading the new annie jacobsen so I can stay up to date on meticulously researched horrifying scenarios about the end of the world

@Ben_M5rtin Where’s your OS?

[Dov Alperin @dovunderscore]

@ShadajL @conor_power23 We should definitely catch up at some point!

I confess to not yet having a good intuition for what kani is able to reason about these days. I've mostly used to prove that pointer math I was doing was safe. I need to play with it more.

@acodechef you didn't. people treat containers as a security boundary when they are not!!

[Dov Alperin @dovunderscore]

Containers never were a security boundary

[Zhenpeng (Leo) Lin @Markak_]

Containers are no longer a security boundary.

Over the past few months, we’ve seen a crazy amount of Linux kernel vulnerabilities and exploits. This has forced us to rethink the security of infrastructure that relies heavily on the underlying kernel, especially containers.

As models become more capable, the barrier to escaping a container has fallen so much that adversaries can now generate working kernel exploits in a single shot. CVE-2026-80521 is one such example. We discovered it using dfs-large1 from @depthfirstlabs and generated the exploit in one shot with GPT-5.6 Sol. The exploit still works on the latest Ubuntu 26.04 release because the fix has not yet been backported.

Labs are severely overcomplicating this whole RSI thing. Just show AGI is in NP, then have an agent swarm prove P=NP real quick.

[Dov Alperin @dovunderscore]

workshopping this

[Dov Alperin @dovunderscore]

Gonna be honest “vigilantism” is a wildly telling word choice here

[Prime Minister of Israel @IsraeliPM]

WATCH: PMO Spokesman @DoronSpielman addresses the violence in Judea and Samaria.

Israel’s position is clear: No vigilantism. Those responsible will be apprehended and brought to justice.

Anything north of the Bronx is upstate

[Dov Alperin @dovunderscore]

I’m excited for the inevitable documentary about this whole thing

[TO @TO]

The goal is audacious: open 100 Corgi Cafes this year around the world.

This is the challenge of a lifetime. It hasn’t been easy...and I wouldn’t want it any other way.

I’m all in. Every city. Every cafe. Whatever it takes.

We’re just getting started. 🐶🧡

@JustJake I think that’s called s3 express one zone :)

@mycoliza @JulesJacobs5 A lot of the time to get it to do APIs I don’t hate I end up “I typed this trait definition, use it and do not change it at all please” which I’ve found strikes a decent balance
