Looks good! Did you build your own text editor? The markup doesn't look familiar. (Would recommend grabbing one off-the-shelf that handles cross-paragraph selections and concurrent edits, will save you a world of pain)

I just loaded Hacker News after a WaniKani session.
Any recs for moving this into Anki? I already use Anki for cards I created while going through Genki with my tutor, and world capitals.
As a framework-enjoyer, I'm finding this helpful to leaf through just to learn about modern web platform tech.

Looks like it's a special font provided by https://github.com/jdan/98.css (Which has come a long way in the past couple of years, despite still being 0.1.x)
Although there is a CSS rule for manipulating how fonts are anti-aliased, it was never standardized, and Firefox doesn't implement the vital no-smoothing option: https://developer.mozilla.org/en-US/docs/Web/CSS/font-smooth
Maybe with enough retro revivals it will receive attention.
I should probably 1.0 it and call it a day, it's pretty much done. In the back of my mind I've thought of making the markup more amenable to LLMs like Sonnet (maybe with tailwind style utility classes)

Shameless plug, feel free to copy my setup! https://github.com/jdan/try-j
I made it myself.
I use Obsidian and the Spaced Repetition plugin, which I highly recommend if you want a super simple markdown format for flashcards and use Obsidian:

There are pre-made Geoguessr decks for Anki. However, I wouldn't recommend using them. In my experience, a fundamental part of spaced repetition's efficacy is in creating the flashcards yourself.
For example I have a random location flashcard section where I will screenshot a location which is very unique looking, and I missed in game. When I later review my deck I'm way more likely to properly recall it because I remember the context of making the card. And when that location shows up in game, I will 100% remember it, which has won me several games.
If there's interest I can write a post about this.

+1 to this, have found the same when going through the Genki Japanese-language textbook.
I'm assuming you're finding your workflow is just a little too annoying with Anki? I haven't yet strayed from it, but may check out your Obsidian setup.
I've been fiddling with the Collatz Conjecture off and on for years now. I'm convinced I found a pattern that I haven't been able to find mentioned anywhere. Granted, that could be because I lack the mathematical language needed to search for it.
First, I'm going to use an implicit even step after the odd step, as 3*odd + 1 always equals even. If you look at the path a number takes to its next lowest number, for example 5->8->4, visualize it by just looking at the even and odd steps like so: 5->10, you will see that other numbers follow a similar pattern:
9->10
13->10
17->10
What do these number have in common? They follow the pattern 5 + k(2^n) where n is the number of even steps (with the implicit even step, two in this case).
For another example, look at 7:
7->1110100
Seven even steps, so the next number will be 7 + 2^7 = 135:
135->1110100
I'd love to hear if this has been found and documented somewhere. If not, I have additional ramblings to share.

I’m forking Shopify’s polaris-react library for my personal use and some of the components are clearly made to people who don’t know how to use CSS.
For example, there’s a component called “InlineStack” which is just a javascript wrapper for a div with flex. This stuff drives me nuts.
You're leaving out the most important bit of a component like InlineStack: the props [0]. Yes you can just apply `display: flex` to the div you're working on, but like any proper abstraction these guardrails make using flexbox correctly the easiest path forward (the "pit of a success").

Astronomy is one of the few sciences that I've studied that has given me existential dread.
In particular, the scale of the universe just hurts my brain: If you were to scale down the Sun to the size of a coarse grain of sand (1 mm), then the orbit of the Earth would be about 20 cm across, with the planet itself being microscopic at this scale (10 micrometers). Jupiter would be a barely visible speck 55cm from the Sun.
At this incredibly tiny scale, the next nearest star in the galaxy is about 30 kilometers (18 miles) away! That's roughly the same as a trip across a typical city, but our Voyager probes at this scale have gone only 15 meters over a period of 45 years! That's comparable to the rate at which hair grows (1 mm/day).
Hence, a good mental model for thinking about the scale of our galaxy is: Stars are grains of sand separated by tens of kilometers on average across a circular space the size of the orbit of the Moon.
Strangely enough the analogies that scale earth's orbit to ~centimeters and nearby stars to ~kilometers actually makes me think we're not that far from other stars! Once you scale it back up and start thinking about travel times measured in ~generations I'm humbled again.

Impressive!
