Zeccon Rivers Cuomo is an active developer on GitHub

The two pieces of software I'm most proud of having written in college were a simple NFS driver and a simple GET-only HTTP server. There's just something magical about seeing your software not only working, but also integrating with something else that's "real". (In this case, being able to mount a network drive in the OS and opening a page in a real browser)

Zeccon Welcome to the Chata Programming Language

FWIW, "chata" in Portuguese means something like "boring" and "annoying". But at least it's not vulgar or obscene.

Naming for an international audience is hard.

Zeccon Why did older computers and OSes use UPPER case instead of lower case?

That's a good point. I added that rule (font-variant-numeric: slashed-zero;) to the font preview using the browser's devtools, and I saw no difference.

Zeccon Why did older computers and OSes use UPPER case instead of lower case?

Hard disagree.

The header image on the website shows slashed zeroes, but the font preview doesn't, which is unexpected. In fact when previewing in Google Fonts there's barely any visual distinction between uppercase letter O and zero. There's only a very slight difference in width which you actually have to look for. Punctuation isn't centered in their box and leaves so much tailing space the test text `5240N 15:01 .84 8,9` reads like `5240N 15: 01 . 84 8, 9`

These problems don't exist as much in the variable width font, where there is no tailing space in the punctuation and the uppercase Os are rounder.

There's also some weird pinching in the corners of N. 1, l and I are perfectly distinguishable though, so at least it's got that going for it.

Have you tried accessing `arguments.callee`[0]? It is unfortunately deprecated and might throw an error. I've never tried it myself as I rarely use breakpoints in the debugger.

Zeccon Adult Attention-Deficit/Hyperactivity Disorder and the Risk of Dementia

A percentage always reflects a ratio between a quantity and another reference quantity. When you say a value is 6 percent higher, you are saying it went from X to (X + X*(6/100)) = (X*106/100) = 106% of the value you had before (whatever it was).

When you say it is 6 percentage points higher it means you had a percentage Y% and it is now (Y+6)%, a value which cannot be determined unless you know Y, never mind the reference absolute value it relates to.

In this particular case you can say it went from 7% to 13.2%, so if you ignore "%" as the unit the actual change is from 7 to 13.2; a ((13.2-7)/7) ≈ 0.8857 = 88% change. Had the original percentage been say 67%, a 6.2 p.p. change would have increased the percentage to 73.2%; a much smaller ((73.2-67)/67) ≈ 0.0925 = 9% change.

Had the change been "six percent of seven percent", the new value would be 7+7*(6/100) = 7.42 (percent).

Zeccon Internals of async / await in JavaScript

You can use them in any place where you want to return a bunch of values, but not necessarily all in one go. This goes for bytes in a Uint8Array, points you want to draw in canvas, DOM elements you are selecting or generating on the fy, data objects you've downloaded from somewhere, etc.

The advantage of generators over arrays is that you don't have to allocate a large array, so you can handle large numbers of elements while keeping a lower memory footprint.

They can also hide batching/chunking logic. You could have code that repeatedly downloads of separate JSON files with 200, or 500, or 5000 elements at a time, then return a generator that goes through each element at a time. The consuming code will be none the wiser.

Zeccon Fomos: Experimental OS, built with Rust

Sounds like it's a framebuffer, and yes the apps draw themselves.

Looking at the source code of the cursor app [0], we can see it draws the mouse cursor and skips the rest. The transparent console app [1] is doing something more complicated which I haven't tried to fully understand, but which definitely involves massaging pixels and even temporarily saves pixel data in ctx.store.b1 and ctx.store.b2 so it looks like some kind of double buffering.
