Multicellularity is polyphyletic Updated 2025-07-16
From Wikipedia:
Multicellularity has evolved independently at least 25 times in eukaryotes
and:
Complex multicellular organisms evolved only in six eukaryotic groups: animals, symbiomycotan fungi, brown algae, red algae, green algae, and land plants.
csvkit Updated 2025-07-16
Lots of features, but slow because written in Python. A faster version may be csvtools. Also some annoyances like obtuse header handing and missing features like grep + cut in one go: csvgrep and select column in csvkit.
csvtools Updated 2025-07-16
A fast version of a somewhat subset of csvkit, written in C.
Build failed with undefined reference to pcre_config on Ubuntu 23.04: github.com/DavyLandman/csvtools/issues/18
Unfortunately it is lacking some basic options, like optional header + selecting column by index on csvgrep (though csvcut has it). The project seems kind of dead.
Also unclear if it allows to filter + print only selected columns.

BrainSimII Updated 2025-07-16
The video from futureai.guru/technologies/brian-simulator-ii-open-source-agi-toolkit/ shows a demo of the possibly non open source version. They have a GUI neuron viewer and editor, which is kind of cool.

Mostly on vintage electronics. Lots of focus on microwave, which he has worked a lot with.
Has been going wild with restoration and reverse engineering of the Apollo moon mission.

yolov5-pip Updated 2025-07-16
OK, now we're talking, two liner and you get a window showing bounding box object detection from your webcam feed!
python -m pip install -U yolov5==7.0.9
yolov5 detect --source 0
The accuracy is crap for anything but people. But still. Well done. Tested on Ubuntu 22.10, P51.

By looking at this more general point of view, we could ask ourselves what happens to the group if instead of the dot product we took a more general bilinear form, e.g.:
The answers to those questions are given by the Sylvester's law of inertia at Section "All indefinite orthogonal groups of matrices of equal metric signature are isomorphic".
Like all poor countries, Brazil's lack of money and scientific culture severely limit its ability to make technological and scientific advances.
While this sounds obvious, Ciro Santilli has felt it first hand since he moved from Brazil to Europe, and it is just shocking.
In the city of Santos for example, despite being a dream place from the natural point of view, it would be completely impossible to achieve any deep tech technical advance that impacts the world. In Europe however, there are several several places where this can happen.

Good talk, explains how everything happened in the perfect location at the perfect time: unemployed people who knew how to code, bought an iPhone, the next big platform, at its very beginning, they had just release the required push notifications API, and he travelled a lot and knew how much SMS sucked, especially international.
