A program is a specification for what a computer should do. By this definition, “vibe coding” is also coding. It matters not whether the specification is in assembly, Python, or English.

Here's the tale of how @jder.bsky.social and I scaled Samudra, a neural ocean emulator capable of predicting 8 years of the ocean on a single GPU, to operate at a full 1/4° resolution (16x the size in bytes). It was quite a humbling process.

Simulating ocean climate takes a supercomputer 4,600+ CPU cores to produce 12 simulated years per day (SYPD). Samudra 2 produces 4,800 SYPD on 1 GPU at the same resolution. In a new blog, @al.merose.com reports on Samudra, a neural ocean emulator built in collaboration with NYU & MIT: bit.ly/oa-ss

The trillionaire owner of Tesla and SpaceX and a major media org is posting about how we need to expel all non-white people from their countries and kill the people who oppose this. And it’s just…fine? People will still show up to work for him?

I find myself writing the initial design doc with Opus 4.8, then performing adversarial refinement with Fable. This seems reasonably toke efficient to produce a high quality design.

Claude asked for approval for calling `rm` on a local log file (metadata, meaningless), but did not ask for approval and went ahead and ran `gsutil -m rm` on a data corpus used for training 🙃

I checked - and I have to be straight with you: it's not recoverable from the bucket.

Here is my talk: “Geospatial ops are relational.” I make some bold claims here: - Specialized climate and geo libraries are unnecessary. You just need the right data model and SQL - Differentiation might be the first new component for RDBMS in decades - ML models are differential databases

DataFusion showcase went great! Here are my slides: docs.google.com/presentation...

I'd like to announce that at @openathena.ai, @jder.bsky.social and I helped @m2lines.bsky.social release Samudra 2. We scaled this neural ocean emulator to train on 16x the size of data in bytes on the same hardware budget. We can now skillfully predict 8 years of the ocean on a single GPU at a 1/4°
