It seems in my bank they trust AI a lot. Periodically, we have to provide our ID card as proof of existence and their AI system has decided to change both my name and my father's name based on their scan of the documents, on separate accounts and on separate incidents. Humanity is doomed. 1/

Here's a power metal summary of scipost.org/10.21468/Sci.... It is fairly comprehensive and accurate. The text is generated by codex, the graphic by chatGPT, and the music by ACE-step. The research is of me and my coauthors :) I am honestly impressed by ACE-step.

1/4 RIP Micius 🛰️ The world's first quantum satellite crashed into the Pacific last week (to the west of Ecuador) after an almost 10-year mission Also known as Mozi (& QUESS) it was famously the first to teleport a photon to space (or at least its quantum state) 🧪⚛️ www.nature.com/articles/nat...

We take randomness for granted.
 Early PRNGs were BAD. Thousands of scientific papers used to rely on RANDU, created by IBM in the 1960s.

In 1D space, it looks ok! Map in 3D…you start to see the issues. Now, there *was* a better solution...but it would cost you.

I'm sorry, #Numpy, but this does not make any sense. Indexing by a vector is supposed to make a copy and return a contiguous array. Otherwise your interface is lying: B or R[:,I] is not a C_CONTIGUOUS array.

Nepal golden tips black tea. A bit more astringent, but the Chinese steeping method (direct immersion, more tea, short steeps 5-20s) modulates the release of more astringent compounds, which come out more slowly. Result is very mellow. Best practical thing I learnt in 2025.

There should be a special place in hell for people who steal umbrellas from public spaces in rainy days.

Repetimos migas, pero está vez con el acompañamiento completo (según receta de Encinasola)

Enjoying an aged Liu Bao tea in this quiet Sunday morning. Love these earthy flavors. Take the mind away from the cold. Best thing is that with these loose leaf teas one can then cook (literally boil!) up to a litre of tea for a thermos. Not as nice a gongfu style, but never bitter.

Another very exhaustive video from @techconnectify.bsky.social , only topped in my mind by the dishwasher and rice cooker ones, because these had practical impact in my life.

Implemented category-based caching. The dailyarxiv.com app should no longer bother arXiv so often and be a bit more responsive.

100% agree. Especially since we have author IDs that are matched to the papers when they are claimed!

As a side note, the reader is a bit fragile because due to CORS restrictions, my app cannot directly ping the arXiv and I had to write a proxy. Unfortunately, people are using this proxy to train their AI models -- one such user directly complained to me that the reader was not working. Thus... 1/

Somebody should throw some serious money into OpenBLAS. It has become the de-facto standard in Python numerical libraries and it needs some love. Specifically in the multithreading area, where its performance can be a bit nonlinear. www.openmathlib.org/OpenBLAS/
