Some folks asked if old climate models were just continuing observed linear increases in temperatures. This misrepresents what physics-based climate models do (they aren't curve fitting), but also ignores that in ~1970 there was little observed warming:

Scientists have been publishing climate models since ~1970.
A good way to evaluate their skill is to compare what they expected to happen in the years after the model was published to observed climate changes.
It turns out most models were pretty spot-on:

transformer-circuits dot pub by Anthropic is maybe the most gorgeous custom made research publishing platform I've ever seen
it's so gorgeous and has so many neat features
triple the salary of the dude who built this and fire the web team, ask (beg) him to spend 20% of his time on it

Yesterday I had this idea that you could figure out stitch counts by finding an FFT peak from a guage swatch picture. It works!

I am finding my "journey" to do more front-end work incredibly frustrating and unrewarding. Today I figured out part of the reason is because of the mismatch between my expectations based on seeing features everywhere and wanting them and my ability.

Control theory is way more important to fixing ML than people realize. Control theory is just continuous reinforcement learning after all.

One thing that I have learned about myself in the last 5 years is that I love remote work and don't ever want to work in an open-plan office.

I hate it when people say "this technology allowed a person to fly a drone using only their thoughts". That focuses on the wrong thing. It's really "this technology allowed a person to fly a drone without moving any part of their body" or something similar. It's not telekenesis.

Weird confession: I run all of my analyses on my local laptop. The closest I get to running remote compute is that Snowflake runs big SQL stuff for me. I've never been able to figure out how to use Sagemaker or any of the cloud compute options people rave about

I just found out about "GROUP BY ALL" from DuckDB, turns out it's also supported in Snowflake, but not in PostgreSQL. I have wanted this for a very long time. duckdb.org/docs/sql/query_syβ¦

More than 3 billion people are vulnerable to #climatechange & more in the future will be exposed to the consequences of climate change.
Reducing vulnerability to climate change is therefore indispensable for climate justice & just transitions.
