a good run this morning preparing for my first 10k

@ctatedev no doubt this is impressive, but what it means design for ai agents?

I built Zero in 3 days. I didn't expect it to compile. I didn't expect it to mostly self-host. I definitely didn't expect it to work at all. Inspired partly by Bun's rewrite to Rust, Zero started as an experiment. Honestly, the project says more about where AI is today than it does about the language itself. It took more than 3,000 agent tasks to get here, and it's still nowhere near ready for serious comparisons, benchmarks or evals. But the goal is bigger than the current result. The hope is to either create a new language with tooling designed for agents from the ground up, or take learnings and apply it back to existing languages and ecosystems. The ideas are simple: 1. Make languages (and new versions) easy for agents to learn, adapt to and fix on the fly, even when not in the training data. 2. Build a standard library comprehensive enough that most projects don't need external dependencies. 3. Create a tight, fast development loop that even small models can reliably work with. I've never wanted to create a programming language. But after repeatedly running into the same problems, safe but slow builds, fast but unsafe builds, agents struggling with new languages and version changes, wanting faster builds, smaller bundles and better DX, I started wondering: Could accelerated, agent-driven iteration produce a language and tooling stack designed around these constraints from the start? So Zero was born.

@tannerlinsley thank you for your hard work!

Despite the “TanStack”-mention firehouse getting cranked 10,000x this week, I still insisted on reading every single one (not a bot!). Any single person would have probably gone insane, but I’m not alone! The people on my team are amazing (the open source ones and the ones that I live with). They kept me grounded and we got to work. Result? My dedication to this craft, this ecosystem, and its people are higher than ever before. Get ready for an awesome TanStack summer.

@mcuban great idea: let’s make the heavily subsidized tokens more expensive

We should federally tax Tokens at the Provider level. Not a lot. Less than 50c per million tokens. It will accomplish 4 things (at least ) 1. It will push the big AI players to optimize tokenization, caching , routing and localization Which will 2. Reduce energy usage. Saving them in energy costs more than what they paid in tax and reducing strain created by the growth in energy consumption Which will 3. Generate maybe 10 billion dollars a year to start, but over the next ten years could grow 30x to 100x Which will 4. Create a source of funding to pay down the federal debt or deploy, in response to the things AI brings that we don’t expect or don’t like At some point the models will pass it on to customers. Of course. That’s ok. Customers will have the ability to choose between providers. Or to do everything using open source models locally. Thoughts ?

@rand_longevity i don’t think UBI will be really implemented

i mean lets be honest, if you are under 50 you and never gonna see that social security money you will just have to live with universal basic income

when i saw this icon i thought my screen had issues lol x.com/waitbutwhy/sta…

don't share password with anyone, if they are compromised you'll be vulnerable

finally i can use tanstack

zero human code

@ctatedev what makes this the programming language for agents?

Introducing Zero The programming language for agents. I wanted a systems language that was faster, smaller, and easier for agents to use and repair. Explicit capabilities. JSON diagnostics. Typed safe fixes. Made for agents on day zero.

Vibe Coding: Building the App @levelsio Asked For - Part 4 x.com/i/broadcasts/1…

@mattpocockuk i keep my skills short and very specific

Long skills are such a red flag to me - Hard to audit (and therefore, trust) - Hard to edit (more text, harder to maintain) - Expensive to run (more text, more tokens) The shorter the skill, the better IMO

@ChShersh human slop is worst than ai slop

I've seen man-made horror code bases much worse than the ugliest vibe slop you ever encountered

@rand_longevity just black, like god intended

what do you put in your morning coffee?

@ChShersh i thought you were working from the US

I think y'all need to look at a proper CV for once

the Bun rewrite to rust is impressive

this the best to create new projects

@devadam88 I did it in 26:10 yesterday

As a developer, in what time can you run 5km? 🏃

I’ve just got layoff, time to convert into an AI bro

@ThePrimeagen you were the chosen one

i regret to inform you that i have to learn python
