i enjoy this flowchart explaining how bash decides whether to use .bashrc or .bash_profile https://blog.flowblok.id.au/2013-02/shell-startup-scripts.html, mostly because it makes me understand better why I could never understand how the 2 config files worked when I used bash

The demoscene has become a national UNESCO heritage in Sweden! I was part of making the application, so ofc I think it's great, but I wrote a little bit about how difficult it is to generalize the demoscene. https://www.goto80.com/the-demoscene-as-a-unesco-heritage-in-sweden

I have made a video about the ARC-AGI-2 dataset.

PlanExe is my hobby project. Here is a plan for developing the next Grand Theft Auto (GTA)

I have made an open source project for making plans, such as a "Robot Olympics". Do you think the plan makes sense?

Hardware on my bucket list:
- IBM’s Model M click keyboard
- Nvidia DIGITS
- FLEX 2 Saline - 32 Channel Wireless EEG Head Cap System

Zelenskyy said thank you many times. Yet the americans weren't satisfied.

Disgusting.

Seems like a planned attack on Zelenskyy on live TV.

Here's my list of the pop stuff:

The current administration has proposed to cap indirect costs (which covers laboratory maintenance, equipment provision and salaries for support and administrative staff) at the National Institute for Health at 15%, from the current levels of 50%-70%, which will likely make many ongoing research projects impossible to continue in their current form.

My own mathematics department receives very little direct funding from the #nih, but already the mere *possibility* of such a drastic cap has impacted us; we have been unable to make a job offer to an outstanding candidate because the budget uncertainty created by this proposal has forced my university to close off almost all discretionary sources of funding for faculty hiring at all departments, regardless of their level of NIH support.

My university, as well as many others, are circulating a letter of support for NIH funding of biomedical research, for which the US is currently an international leader. The letter is available for anyone to sign at https://docs.google.com/forms/d/1Agzz5mQgfEMpLlBhoE4ZyHdiTvdc9O84zF4vNEHyKTI/viewform?edit_requested=true

I spent several hours yesterday on recording a video about what the output files are.

Over the last month I have made some silly AI experiments. And eventually it has turned into a planning AI, that can take the users vague description of a project and create a plan for it!

Interview with the guy that made the visual programming language (ComfyUI).
The UI has wires between the nodes, and the backend is python.

The number pi has an evil twin! It's a number called ϖ with many properties similar to π. There are even mutant trig functions connected to this number, called sl and cl.

So maybe while you were studying trig in high school, some kid in another galaxy was having to memorize all the identities for these other functions.

I doubt it. Just as pi and trig functions are connected to the circle, this number ϖ and its mutant trig functions are connected to a curve shaped like the symbol for infinity, ∞. But this curve is just less important than the circle. I'm not enough of a cultural relativist to believe there's a civilization that cares more about the shape ∞ than the shape ◯.

This ∞-shaped curve is called a 'lemniscate', and ϖ is called the 'lemniscate constant'. I'll show you the lemniscate in my next post.

A civilization will probably only get interested in ϖ when it gets interested in the lemniscate.... or the deeper math it's connected to. On our planet, it was Bernoulli, Euler and Gauss who discovered this math.

(Why does unicode even have the symbol ϖ? Here's why: it's a script version of the Greek letter pi, sometimes called 'varpi' or 'pomega'.)
