- colleague: Do you have that data?
- me: No. I have to extract/compute it.
- colleague: You can do it with Gemini.
- me: Please, don't tell me to use Gemini. (I will do it however I want to).
- me later: Here is the data (without using Gemini, just python)
Felix is working in a projection in PROJ: Snyder Polyhedral Equal Area
He added this interesting animation.

*PROJ in the browser*
Finally, after a long time and learning a lot in the process, I am getting a webpage that uses PROJ to perform coordinate transformations (similar to cs2cs)
https://jjimenezshaw.github.io/wasm-proj/transform.html
Best features:
- fast!
- it uses grid files when needed, downloading only the needed part of them.
There's another one that replicates projinfo:
https://jjimenezshaw.github.io/wasm-proj/projinfo.html
It has its js library behind it. I'm still developing it, improving it & adding more features.
Enjoy!

The AI Great Leap Forward
In 1958, Mao ordered every village in China to produce steel. Farmers melted down their cooking pots in backyard furnaces and reported spectacular numbers. The steel was useless. The crops rotted. Thirty million people starved.
In 2026, every other company is having top down mandate on AI transformation.
Same energy.

"How are you an engineer in this f*cking country?"
PROJ 9.8.1 was released today April 10th 🥳
More info on https://proj.org/en/9.8/news.html
This early bug-fix release reverts to an earlier version of EPSG, to avoid some issues found in 9.8.0 for the ETRS89 datum ensemble.
https://spatialreference.org/ and
https://crs-explorer.proj.org/ are already up to date.

Recently I bought this tiny e-book to my wife
Xteink X4

and she is very happy with it. She can literally put it in her pocket and read anywhere (and she does).
It definitely needs this other (open source) firmware

The original one is not good.
"The zero coordinate point of the Swiss National Survey LV95"... in Madeira.
A friend having some holidays in Madeira found this: a mark for the 0,0 of the Swiss CRS.
(Well, the zero is on the sea, but not that far ;)

El video definitivo (más de una hora) sobre los #VentiladoresDeTecho

One company paid $500,000,000 for AI in one month
An AI consultant told Axios that one of their clients recently spent half a billion dollars in a month on Claude licenses from Anthropic. How did the company rack up such an insanely high bill? Its employees apparently had no limit on how many licenses they could use, leaving them free to splurge on as much Claude as possible. (more in video description)

Por si os gusta la historia de la geodesia, en este video hablan de la definición del nivel del mar en Alicante y de la primera red geodésica en España, del siglo XIX.

En esos trabajos fue fundamental Carlos Ibáñez e Ibáñez de Ibero, que fue el primer presidente del Comité Internacional de Pesos y Medidas y de la Asociación Internacional de Geodesia.
