vatsachak··on Claude Code sends your email address to websites
The design decision actually makes sense though.

It's just that Anthropic needs to create an email per user and use it for web searches.

I can do this for you Anthropic. Just give me the tokens and your base salary

vatsachak··on The Stacks Project, Formalized in Lean
Okay this is actually useful AI formalization. But the stacks project is basically Lean in natural language anyways, so it makes sense why its high quality.
vatsachak··on MCP Explained
Horribly designed
vatsachak··on US midterm elections 2026 live updates: Democrats win Senate control and edge
You'd rather read another postgres hacks article written by Claude than discuss the midterms, the second largest political event in the United States?
vatsachak··on Could a modern chess engine on a Pentium have defeated Kasparov in 1996?
A modern chess engine plays at like 900 elo above Magnus Carlsen? Why is there any doubt it would beat Kasparov
vatsachak··on Embedding boolean circuits in a neural network
Okay but the difficulty here is getting the LLM to use the neural circuit effectively without training just wiping out the circuit. You'd need to have the circuit be a differentiable black box where gradients cannot affect the black box
vatsachak··on Scaling Git at OpenAI
Impressive. We're definitely seeing LLMs help create real novel software
vatsachak··on Supermarket freezers across Europe hit by second suspected cyber-attack
Have the freezer connected to an air gapped grocery local server. Fixed
vatsachak··on America on Data Centers: listen to 10,000+ city council comments
I'm pro AI and data center but a lot of construction is short sighted.

They should invest money into improving electric and community infrastructure. There are so many win-wins to be had and they fumbled

vatsachak··on Postgres 19 is late because so many more bugs are being found now
What? AI can't easily implement features. Just write a spec, ask if to expand it and then ask it to implement it
vatsachak··on Mathematics has changed. Let's act like it
I mean he's basically admitting that math academia is outdated.

If we don't interview candidates based on results, what is it? Politics. It already was. I had a JEMS paper in grad school and got zero postdoc offers. Many other cases.

The real shift is that math will become a hobbyists game. Make money other ways and then spend your money on humans and tokens to solve your problems.

vatsachak··on Reading and writing are less symmetric than you (probably) think
This is true even at the CPU cache level so it's probably going to trickle down all the way.

For example Jon G gave a talk at Jane Street about how he had a mysterious performance bug that was later attributed to cores fighting over the same cache line

vatsachak··on Serbia just elected the world's brainiest parliament
Man hacker news hates academically successful people
vatsachak··on Simple circuits can create complex behaviors
A similar mechanism is how lactobacillus actually find food even though their motor propels them in random directions.

They have sensors for the concentration of food and basically stop moving when it's good enough and start when it's low.

vatsachak··on OpenAI raises less than half of $30B target
That's 150B shaved off like it's nothing lol
vatsachak··on OpenAI raises less than half of $30B target
I mean the super groups are going to break up and make their own bands.

My only request is to keep Opus 5.5 alive

vatsachak··on Edit an SQLite database in your browser
Nah, not irrational. No application should show the logic at the forefront. It's just claude-ese convention from RLVR
vatsachak··on Edit an SQLite database in your browser
This is like a one hour claude project

I doubt this

vatsachak··on noalloc: Tooling and libraries to enforce zero heap allocations in Golang
I've been writing Rust for a year and change professionally, also as a hobby, and even though I love it, it's really annoying to choose the allocation model and lifetime model at every step.

For example,

- A field in a struct cannot borrow another field so now you'd have to create two structs. I guess you could write an impl to borrow that field instead of storing the borrow.

- In simulation software I wrote I found that mimalloc does just as good as bumpalo (within 5%) so carrying a bump everywhere was useless. Not really a rust issue but rather a loss of faith in manual memory management for me.

- Eventually over time you start adding Arc<Fn(Blah)->Foo> everywhere and Box, Arc and friends start coming in. But you can't have cyclical references there so you have to use Weak. And you have to use OnceCell or LazyCell or LazyLock for things that should run at start time.

Rust is really great for the crates, but ...

For applications which are not absolutely performance critical and cannot* be stated pretty easily in linear logic + clone + drop you can get away with Haskell

vatsachak··on noalloc: Tooling and libraries to enforce zero heap allocations in Golang
Lifetime and smart pointer hell is real though.
vatsachak··on noalloc: Tooling and libraries to enforce zero heap allocations in Golang
I think that people hyperoptimize for no reason though. How many applications are there that require no GC? I feel like you can write the no-gc code in Rust and then just use it from the C ABI from any GC language.
vatsachak··on We won't "just hang out"
I made friends online in programming even after Claude Code. Other people's projects are cool
vatsachak··on Tomáš Mikolov awarded the Medal of Merit by the President of the Czech Republic
I remember being presented Word2Vec as an undergrad in 2016 and I could not predict the sci-fi reality that is today
vatsachak··on Scaling Hierarchical Networks
They are though. Bytes are raw data and the architecture chooses the tokens
vatsachak··on Gemini 4 Carbon is the new #1 on the Artificial Analysis Intelligence Index v5
At this point frontier models are good enough to be a pair programmer. But only OAI and Anthropic offer good limits. Maybe they're burning money but if the Google limits are the future of usage style accounts then we all have to get used to API
vatsachak··on Dayjob: Tax – evaluating AI agents on 50 professional tax assignments
Nice. Opus 5.5 is crazy good at engineering ideas into life. Really cool stuff, using "code is data" with Lean
vatsachak··on Scaling Hierarchical Networks
Oh man, that haskell quicksort tokenization has got me feeling great
vatsachak··on At least 68 killed in Spanish high-speed train crash
As an American tourist who took an HSR in Spain 4 years ago, the number of crashes since then are concerning
vatsachak··on Dayjob: Tax – evaluating AI agents on 50 professional tax assignments
Nice. Is the lean used to formalize formulas?
