@olvrgln All fun and games until the weather gets bad

@olvrgln @shawkisukkar Thinking just feels like a form of neurotic anxiety.

It manifests everywhere. In writing you’ll notice every comment is hedged. In code, you’ll notice that every function is overly defensive

[Cal @Cool_Cow_Cal]

@olvrgln @shawkisukkar Slowest model I’ve ever used, I have to yell at it to stop overthinking every solution. But it’s the brightest by far for deep research.

We shouldn’t have to specify thinking levels it should know when to overthink vs not

[Cal @Cool_Cow_Cal]

@olvrgln They never know when to stop. If you’re not careful you can refactor forever, adding endless code and nonsense

Sending this to friends and saying "you'd definitely die this way"

[doomer @uncledoomer]

would be very interesting to still have lobsters this size around today. where's little jimmy? oh he got too close to the beach and was dragged away by a lobster. very tragic. but such is life in new england.

Explaining this to the girls I ran over while day drunk

[David @blissposting]

Silly level of drunk but my point is you gotta treat the citi bike as much like a horse as you can. The Citi bike has a soul. And you gotta respect that

[Mr. Chau @Srirachachau]

Everyone I know says they cried after seeing The Sheep Detective...what's going on in that movie

[Cal @Cool_Cow_Cal]

@vers_laLune unrivaled sound design but the story felt pointless

[Cal @Cool_Cow_Cal]

@LinkofSunshine The tide is turning for sure, but it's frustratingly slow and I'm afraid I'll be an old man before we get truly good urban policy

curing years of depression with 20 minutes of citibike around nyc

@zechengzh Feels very similar to Mesa?

[Oliver @olvrgln]

Introducing Mesa: the most powerful filesystem ever built, designed specifically for enterprise AI agents.

Every team building agents eventually hits the same wall: where do the files live?

Not the chat history, the actual artifacts the agent works on.
> The contracts your agent redlined
> The claim files it updated
> The 200-page audit report it edited overnight while you were asleep

Today those documents live in a sandbox that dies in 30 minutes, an S3 bucket where concurrent writes clobber each other, or a GitHub repo that was never built to absorb agent-scale traffic.

So we built Mesa.

The world's first POSIX-compatible filesystem with built-in version control, designed from the ground up for agents. You mount it into your sandbox like any other filesystem. Your agent reads and writes files normally. Behind the scenes every change is versioned, branchable, reviewable, and rollback-able — like a codebase, for any file type.

Mesa provides
– Branches so agents work in parallel without locking
– Durable storage that survives sandbox death
– Sparse materialization so massive document sets load instantly
– Fine-grained access control per agent
– Full history for human review and audit

Design partners are running Mesa in production across legal, healthcare, GTM, business ops, and coding agents.

Private beta is open: link in the comments

My brother (along with his team) has been working pretty hard on this. Shoutout to the launch! If this is relevant to you, go try it!

@shash_yazhi Just fixed it!!

[Cal @Cool_Cow_Cal]

Planted a tree outside my house :)

[Cal @Cool_Cow_Cal]

@shash_yazhi Ahh! You saved me! Going to replant it today

[Cal @Cool_Cow_Cal]

@tenobrus I feel like twitter is willfully misunderstanding FIRE. It’s very rational given the new social contract. Your job isn’t forever. Do you want to be in the position of being laid off at 50 and scrambling to find a new job? At 60? Or hopping from startup to startup when you’re 45?

@parsons_tor POV: it’s the year 39,000 and you’re a tech priest trying to maintain the golden throne

[Cal @Cool_Cow_Cal]

@ryxcommar @theelleaccount i actually lost my goddam mind this winter, I've never seen anything like it

[can @can]

the tide can’t turn fast enough on this. feels like some of it is us giving up on “living in a society” since covid but that dog owners can sidestep all the rules without repercussions is maddening
