I think they’re trying to make a pun based on how the word “gentile” (which literally means not jewish) sounds very similar to “genital”.

For photos, I have been using Immich, and have been very impressed. It has pretty much all the features I want (automatic backup, chronological timeline, mobile/web app, face tagging, semantic search, albums, sharing, etc). It’s a server you self-host though, so setting it up might be a pain if you’ve never done something like that before.

Heh I get it

You have any sources for that? Never heard of this before; sounds interesting.

Disney is gouging customers with a near doubling of subscription costs. (sh.itjust.works)

Disney is raking its customers over the coals with a 75% price hike for their annual subscription (originally $80.) People wonder why piracy is on the rise.Multiple commenters are saying I’m off base about the 75% price increase. My payment less than a year ago was $79.99. Here’s the proof.

And a drop in costs too since their system has to support less users.

Yeah some dude bought the google.com domain via some glitch a while back. Here’s a story about it.

People who are arguing that one way of expressing these concepts is easier to learn/understand than the other are missing the whole point. Mathematical notation was not designed to teach students how to do math or explain how to design algorithms. It was invented to communicate precise, abstract ideas concisely between mathematicians who already understand what the symbols mean.

Mathematicians require a notation that has the flexibility to manipulate mathematical objects/symbols in a way that naturally emphasizes their properties and relationships. Often they don’t even care whether the objects they’re studying are even computable or have a numerical representation. They just need them to have certain properties so that they can be manipulated appropriately.

Discrete sums are a rare example of when the mathematical notation overlaps with the description of an algorithm for computing its value (and the overlap is not even complete; infinite sums are easily represented in math notation but are practically uncomputable when implemented naively). Every other advanced mathematical concept puts a premium on ease of symbol manipulation over computability: integrals, derivatives, matrix multiplication, abstract algebra, etc.

TL;DR math notation is complex because its intended audience is people who already understand it, want maximum flexibility of symbol manipulation, and historically didn’t really care about practical computation.

What is this optimized cmatrix you speak of? The normal one slows my desktop to a crawl when it runs.
