Introduction - Rust for Python Programmers #learn #programming #rust

A comprehensive guide to learning Rust for developers with Python experience. This guide covers everything from basic syntax to advanced patterns, focusing on the conceptual shifts required when moving from a dynamically-typed, garbage-collected language to a statically-typed systems language with compile-time memory safety.


S&P 500 rejects SpaceX, also blocking entry for OpenAI and Anthropic - Ars Technica #economy

Swift entry into the S&P 500 would have triggered $14 billion of passive fund buying for SpaceX, according to Bloomberg Intelligence. The investment research arm of Bloomberg also estimated that OpenAI could have gained more than $8 billion, and Anthropic could have netted $4.6 billion from similar passive buying sprees triggered by their S&P 500 entries.

This is because $7.5 trillion in passively managed funds—popular among both individual investors and institutional investors—follow the S&P 500 by purchasing shares of companies according to their proportional representation in the S&P 500 index. For example, the Vanguard and Fidelity brokerage giants both offer passive investment funds that track the S&P 500 composition.


Cheese Paper #software #productivity

Cheese Paper is not an online service that will sell your data or start charging you a monthly fee for important features. Cheese Paper itself is a purely offline program, so your files never have to leave your computer (except for backups, hopefully). If you want to use Cheese Paper on multiple computers, you will need to sync the files yourself with something like Syncthing, Nextcloud, Google Drive, or Dropbox.

Scientists found that the creatine supplement millions take for muscle gains is quietly raising brain energy levels and slowing early Alzheimer's cognitive decline by 30% - thesciverse #health

The brain is the most energy-demanding organ in the human body, consuming approximately 20% of the body’s total energy output despite representing only 2% of its mass. Neurons do not store meaningful energy reserves. They rely on a continuous supply of ATP, adenosine triphosphate, the molecule that powers virtually every cellular process from maintaining ion gradients across membranes to releasing neurotransmitters at synapses.
