The list of companies that signed this letter is telling (including Nvidia, Meta, Microsoft). Equally telling is the list of companies that did not sign it -- including Google, Amazon.
There are some arguments to stick with "half-way" time -- 30 minutes in the middle between standard and summer time. It does not necessarily solves all the problems but makes a reasonable compromise with farmers who want standard time and many others who prefer summer time.
Thanks for the link to the paper published in 2010 (16 years) ago. The OP article from Brown reads as if they were the first to establish importance of Special Relativity for heavy atoms which is not true.
This is exactly why eigenvalues are less flexible than singular values. You can have a real valued matrix that does not have any eigenvalues in the field of real numbers, all eigenvalues are complex numbers. Examples: rotation matrixes in R^2 have no eigenvalues in R. Singular values, on the other hand, are always real (they are eigenvalues of the Hermitian matrix MM^*) and can be used the same way for the matrices over real (R) or complex (C) numbers, hence extra flexibility. Added bonus -- singular values are never negative.
Instead of "more flexible" a better statement would be -- eigenvalues convey more information than singular values.

What's about EU? EU is bigger than the USA in total population and it has comparable if not larger total GDP. Why did not they step in where USA failed?

Clueless journalist conflates power (megawatts) with energy. They need physics 101. For electrical energy common unit is megawattHour (megawatt drawn for entire hour). A smaller unit would be megaJoule (megawatt drawn for 1 second).
UX in my Audi Q5 (2024) is terrible. With two phones in the car you never know which one is connected and whose google maps is being currently displayed. And then come the buttons designed with a contempt for a driver. I recently had to change a flat tire which is a story in itself. German engineering is soooo different these days.
There was a Tacker Carlson interview with Sam Altman where Tacker probed him on Balaji's murder and Sam quickly got confused and disoriented. Make your own conclusions.
> and uv forcing it into a single project directory made it quite inconvenient and unnecessary duplication of the same sets of libraries.
Actually, uv intelligently uses hardlinks or reflinks
to avoid file duplication. On the surface, venvs in different projects are duplicate, but in reality they reference the same files in the uv's cache.
BTW, pixi does the same. And `pixi global` allows you to create global environments in central location if you prefer this workflow.
EDIT: I forgot to mention an elephant in the room. With agentic AI coding you do want all your dependencies to be under your project root. AI agents run in sandboxes and I do not want to give them extra permissions pocking around in my entire storage. I start an agent in the project root and all my code and .venv are there. This provides sense of locality to the agent. They only need to pock around under the project root and nowhere else.
pixi is a general multi-languge, multi-platform package manager. I am using it now on my new macbook neo as a homebrew _replacement_. Yes, it goes beyond python and allows you to install git, jj, fzf, cmake, compilers, pandoc, and many more.
For python, pixi uses conda-forge and PyPI as package repos and relies on uv's rattler dependency resolver. pixi is as fast as uv (it uses fast code path from uv) but goes further beyond python wheels.
For detail see [0] or google it :-)
> 2. Centralized venv storage — keep .venvs out of your project dirs
I do not like this. virtual environments have been always associated with projects and colocated with them. Moving .venv to centralized storage recreates conda philosophy which is very different from pip/uv approach.
In any case, I am using pixi now and like it a lot.
