This week's tech topic of interest has been Neovim.
I started with Emacs, but in my work as a Linux sysadmin Vim is always available, so I've learned what I need to get around.
Lately Neovim has been coming up as an alternative to tools like vscode, so I started exploring. I've watched a few videos by TJ DeVries and been jumping into the terminal.
Neovim certainly makes me appreciate Vim more. Unfortunately, you're not going to see nvim on work servers - just vanilla vim.

From week to week I jump between different technical topics I find interesting.
Last week it was operating systems - see https://littleosbook.github.io/ - that sent me into a ChatGPT-assisted of trying to understand how context switches work on ARM machines. That led to questions about CPU caches and things like that.
Related - There's a book on "The Linux Memory Manager" by Lorenzo Stoakes coming out this year from No Starch Press. Sounds interesting (if pricey).
Today I've watched a number of videos from the Retrobytes YouTube channel. It's all nerdy stuff - the history of SPARC, History of ARM, a history of old-school terminals like the VT100 and such.
It's narrated by a British fellow. I enjoy the stories he weaves.
I'm not so keen on the old-timey music he runs behind EVERY SECOND of his videos, but I'll put up with it for a bit of computer history.

GLP-1 economics. We don’t yet know how sustained the appetite effects will be however.

Very low power.
