@victorvicpal es complicado luchar contra el #TypicalSpanish

Pero no quita para que se vean muchos avances. Habrá que seguir trabajando para que lo typical malo deje de ser tan typical

El intenso viento en Teruel está provocando sensaciones térmicas de... ¡¡ -10'5 °C !! 🌬️🥶
Fine! After getting 12k visits in less than a day with the article https://en.andros.dev/blog/aa31d744/from-zero-to-a-rag-system-successes-and-failures/ , with 100 comments on Hacker News (and 1 on my website), here is a technical summary of the first few hours:

- Nginx cache solved the 99% of the problems (/media/ , /static/ and HTML render).
- ASGI, with a WebSocket server, worked fine.
- Django performed 100% well
- Django LiveView, with 130 parallel users, worked... surprisingly well. I'm surprised myself!

My server has specifications similar to a Raspbery Pi 4. Don't overthink it: Django + Nginx + Cache -> It is easy to develop and performs well.

A few months ago I was tasked with creating an internal tool for the company's engineers: a Chat that used a local LLM. Nothing extraordinary so far.

I don't think people fully appreciate how apocalyptic things are for US science. I haven't received any new funding since 2024, but I'm still ok since grants are typically for 3 years. This means next year I will be completely out of funding and will have to fire everyone in the lab. It's not great.

In my 25-year career, I’ve never NOT had funding. I typically have 4 to 8 grants, which you need if you’re running an observation science program and have a technician, students, and postdocs.

It's so useful and clever. Thanks #IPython developers for such a great tool 🙏

A Once-in-a-4,433-Year Heat Wave Is Hitting the Western U.S.

It is difficult to describe how bonkers this week’s heat wave is in the southwestern United States. Alan Gerard, a typically even-keeled meteorologist with 35 years of forecasting experience under his belt, attempted to do so in a recent edition of his newsletter, Balanced Weather. He settled on: “j...

Google has known about a bug that breaks VPN apps for 7 months, leaving users exposed with no warning or error, just a VPN app that stopped working in the background.

If you're using ANY VPN on Android, you can help us by getting Google's attention to fix it.

We first reported this bug to Google in September 2025.

Others like @mullvadnet and Wireguard reported it even earlier, in August.

Google's response? "I don't see anything unusual."

Here's what's actually happening ⤵️
