GET EXCITED ABOUT POSTGRES 18

Postgres18 adds asynchronous I/O, which means faster reads for many use cases. This is a part of a bigger series of performance improvements planned. Asynchronous I/O allows workers to optimize idle time and improve system throughput by batching reads. It provides a more predictable and better-performing method for batching operations at the database level. Writes will continue to be synchronous as this is needed for ACID compliance.

UTF-8 IS A BRILLIANT DESIGN

UTF-8 was designed to represent millions of characters from different languages and scripts and still be backward compatible with ASCII. Every ASCII-encoded file is a valid UTF-8 file, and every UTF-8 encoded file that only has ASCII characters is a valid ASCII file. This post gets into how UTF-8 works. A link to a playground for visualizing and playing around with UTF-8 encoding is available in the post.

A.I.'S PROPHET OF DOOM WANTS TO SHUT IT ALL DOWN

Eliezer Yudkowsky, the founder of the Machine Intelligence Research Institute (MIRI), a Berkeley-based nonprofit that studies risks from advanced artificial intelligence, believes that building powerful AI systems is a terrible idea that will end in disaster. He recently released a book co-written with MIRI's president aimed at stopping the development of AI. The book claims that everyone on Earth will die if any company or group anywhere on the planet builds an artificial superintelligence using anything remotely like current techniques. While some may see Yudkowsky as an extremist or a crank, he is a central figure in modern AI history, and his influence on the industry is undeniable.
