The implication seems to be that charter schools are superior, but does that jive with other countries' successes? A commonly given alternative explanation is that the public options in the US are deliberately sabotaged via budget restrictions, and then the resulting poor performance is used to justify further cuts—a similar dynamic has been fairly recently executed in Alberta with public health care.

I thought charter schools and public schools received the same $/student.

Long ago (I first remember doing it in about 1985 with the original Mac watch cursor) this was the standard way to do spinners: somewhere in your processing you incremented the spinner. It was hard to put the increments in the right places to keep the spinner going even when progress was happening, and nearly impossible to make it animate smoothly. This technique is even harder to get right when the processing in question is multithreaded, or if the spinner is part of the UI (as opposed to a cursor) so it has to trigger a redisplay to show up.

So programmers didn’t like it because it was complex, and designers didn’t like it because the animation was jerky.

As a result, the standard way now is to have an independent animation that you just turn on and off, which means you can’t tell if there’s actually any progress being made. Indeed, in modern MacOS, the wait cursor, aka beach ball, comes up if the program stops telling the system not to show it (that is, if it takes too long to process incoming system events). This is nice because it’s completely automatic, but as a result there’s no difference between showing that the program is busy doing something and that the program is permanently frozen.

What’s funny is the jerky animation actually communicates so much more than the smooth animation.

No phones in class, at scale and enforced, feels like a last 5 years thing in K-12. And the trend was very much towards increased digital testing, pre-LLM.

This is pivoting back to paper-based, but it's going to be as messy and slow of a transition as the no-mobile-device one was.

Especially given how much money there is in "AI".

And hamfistedly-handed, will likely leave another generation fucked over with regards to basic education (like the predatory social+mobile adoption before regulation did previously).

I attended high school in the US in the early 00’s and cell phones were absolutely banned from classrooms. You could keep them in your locker and use them between classes, but that was it.

I attended college in the late 00’s, and I don’t think I took a single digital exam. Quizzes, sure, but for final exams even CS was pencil and paper (or a final project, which admittedly will have issues in the post-LLM era).

When I was young there were two types of games I tended to enjoy: single-player games (e.g. Nethack, Half-life, Starcraft, & others with a good story and gameplay, or just deep gameplay) and LAN party games (e.g. Unreal Tournament, Counter Strike, Total Annihilation, Quake II, and similar). LAN party games were more fun at LAN parties than online, and not just because server browsers all kind of sucked. Playing along with other people you can see in the same room is a very different experience from playing along with other people you've never met, can't see, and will never encounter again.

These days my friends are scattered across the country, with jobs & families, and so LAN parties are basically dead. And many new games don't even support LAN play, instead they tend to be optimized for online play with some sort of ranking system.

That leaves single-player games. And really good single-player games are rare, just like really good anything is rare. I find a lot of story-driven singleplayer games have good stories, but crap gameplay, so it's frustrating to try to complete the story. If the story is good enough & the gameplay bad enough I'll just cheat & treat the whole thing more like a book or movie instead of a game, but for a lot of games I just don't bother even with that.

But occasionally a game grabs me. The story is great, and the gameplay is at least good enough, or it's just really good gameplay that stays engaging for a long time (e.g. Slay the Spire). These are few & far between, because making really good games is very difficult.

As I age my tolerance for mediocrity decreases, partly because I already own a whole bunch of still-engaging games I can always play. So I agree with your points. The really great games are rare, far rarer than best-selling games.

FWIW there is a new-ish kind of intermediate genre between classic LAN/ranked multiplayer and single player, which is the whole “survival” genre. Generally speaking, they can be played as single player games, but also allow for small-scale co-op, synchronously or asynchronously. So even if you and a buddy have different schedules, you can make progress separately but still occasionally play together.

Valheim, Grounded, Ark, Satisfactory are a few among many others.

Materials Science and Drug Discovery would suddenly become a lot easier, along with financial modelling (of our entire society possibly) and logistics/supply chains.

They would also be much better at training ML and doing pattern recognition.

Basically anything that requires a massively parallel computation on undeterminable states that are only clear in hindsight. They’re really important actually and its only an unfortunate side-effect that the same solution breaks all our cryptography.

(of course: the offensive wings of our defence ministries really enjoy that side-effect)

From https://scottaaronson.blog/ :

“If you take nothing else from this blog: quantum computers won't solve hard problems instantly by just trying all solutions in parallel.”

What’s the best choice of free desktop PDF Viewer/Editor these days (any OS)?

On Windows I’ve been using PDF-XChange for a decade or so now, but curious if better alternatives have cropped up.

While I disapprove of what the gov is doing here, I think it’s incorrect and unhelpful to put all the blame on them. AIUI, the UK is a democracy and these policies are generally supported by the voters.
