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”.

If you are interested in really understanding wifi technology, the difference between the various versions, practical considerations, and cutting through all the marketing hype, I'd highly recommend reading this website.

Good question. This new material is technically a ceramic, not a metal, so I'd be inclined to say no. But we'd need more information on its electrical properties to say for sure.

Boy then are you going to hate QUALIFY

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.

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

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

I agree, the solution is not as simple as optimizing resource allocation. The problem is both social and economic in nature. The owners of production don't just want money, they want power over others.

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.
