it's 2025, and i'm still writing code that isn't formally verified

[Raaid Tanveer @raaidrt]

@AlterranIRL wait, ada? not klaus?

[Raaid Tanveer @raaidrt]

@AdhvikKanagala well, master is default on git, so using main is cringe (since that means you cared enough to change branch name)

@bcherny feature request: make cc request all permissions it could ever need upfront so that i can look over and approve most things it might need permissions for at the start of the session

@simonw Coding agents are also great at writing AST walkers.

My biggest gripe with writing AST walkers manually is potentially having to case through every node type. Coding agents trivialize solving this problem.

@simonw re: https://t.co/Uv0wlUIS9r

One point that you missed that I think more people should be thinking about now is the value of static analysis and lint rules on code quality.

One of the best ways I've ensured that model output variance stays within bounds is by keeping the variety of bad code that can be written to a minimum.

You can simply create an agent skill for introducing new lint rules, or make AST walkers for detecting code smells, and then enforce that these checks be run on every commit.

Looking for suggestions on clean proofs that I can write on inductive datatypes.

Here's a simple one relating the size and depth of binary trees.

@radokirov probably depends on when a good enough “programming DSL” exists for Lean. I know there are projects like https://t.co/eHlEIHV3We, and even the recent https://t.co/RYShxy0gU5 - but still seems much less than general Math support in Lean.

Velvet, our automated Dafny-style verifier embedded into Lean, has moved to a new repository as a standalone Lean library:

Give it a try!

@dystopiabreaker you don’t need TypeVar’s in Python 3.14 anymore, just write ‘class Ok[T]:’

[Raaid Tanveer @raaidrt]

@AlterranIRL regular languages can be solved with O(1) space in a TM so i feel like this is a moot point - i think what you're asking for is a language with a lower bound space complexity of lg lg n as well right?

[Raaid Tanveer @raaidrt]

@boazbaraktcs @TaliaRinger unless it’s ✨formally verified✨

[Raaid Tanveer @raaidrt]

@amorriscode was the original inspiration Claude Shannon? Or Claude Monet?

[Raaid Tanveer @raaidrt]

@bcherny exclusively on VSCode? is this not supported in the CLI?

[Raaid Tanveer @raaidrt]

well, if everyone used this tool and everyone’s SAT scores improved, then the scores would remain the same I think due to fitting to the normal distribution - I suspect it will become more bimodal due to there being groups of people who take advantage of these tools, and those who don’t

[Raaid Tanveer @raaidrt]

Ok this is really cool

I had an HEIC image (Apple's Image format) for a component I wanted to use with my Raspberry Pi, but Claude is unable to examine anything other than JPG. So, it installed a python library for converting the image to JPG, all from the desktop app!

I wonder if it did this locally or on a sandbox somewhere.

@patrickc @cursor_ai i’d say opus 4.5 was probably the coolest ai breakthrough since gpt-4 - maybe you wanted to replace “since gpt-4” with “since opus 4.5”?

[Raaid Tanveer @raaidrt]

@JeffDean @TaliaRinger wish this feature existed for LaTeX

[Raaid Tanveer @raaidrt]

@collision excellent sequel - but not for the same reasons as you i'd imagine
