I love sci-fi, and I read and watch a lot of it.

Made a list of some good, lesser-known science fiction movies → rakhim.exotext.com/lesser-known...

I knew my bug-fixing deployments were "magical thinking"...
"Manifest" hit #Cambridge Dictionary’s Word of the Year 2024!

However, @Cambridge_Uni warns this "magical thinking" lacks scientific backing and can promote risky behaviors.

Companies die from a lack of cash, which in your average SaaS company means a lack of product market fit.
Engineering waste is not the biggest problem with most 100-engineer orgs, lack of product market fit is. If you can't get 100 geeks pointed in the same direction, roughly aligned with the rest of the company, you're already toast but the smoke alarm just hasn't beeped yet.

For anyone interested in fine-tuning or aligning LLMs, I’m running this free and open course called smol course. It’s not a big deal, it’s just smol.

Un día coma hoxe, o 2 de decembro de 1906, abría as súas portas na Coruña o Dispensario Antituberculoso, situado na emblemática Casa do Sol, fronte ao Paseo do Orzán. Un pequeno edificio que agocha unha gran historia! Segue lendo👇

Speaking of this, the original MapReduce paper contains what I imagine are the first versions of Borg, Jupiter, and Colossus.

El recibo de la opacidad lo pagamos juntos. 💸

Cada contrato oculto, cada euro malgastado, cada acción en la sombra engordan una factura que aceptamos sin rechistar. Pero no tiene por qué ser así.

Podemos investigar más. Informarnos mejor. Exigir cuentas. Incluso aliarnos para cambiar esto.

I just found out that the + button to the left of the language selector allows you to create threads 🤦.

Reviewing BigQuery technical info, I see that Borg orchestrates the communitcation between Dremel, Jupiter, and Colossus.

But what about Galactus???

Recuerdo la vez que leí a alguien contando que el valor de no sé qué era menor que X para todos los subgrupos (por edad) de una cierta población, pero era mayor que X para la población total.
Definitivamente la experiencia de Bluesky para mí es idéntica a la experiencia de Twitter... la cual era una reverenda mierda, las cosas como son. Mucha gente leyéndome, muy poquita interactuando, y la poquita gente que me responde rara vez es para decirme algo positivo.
