That playground is cool. I wonder if there are any 2-way playgrounds where the right side is also editable using a Word / Google Docs style interface (and the changes are reflected in the code-style interface on the left). I've al

When global warming hits, the people who benefited from ignoring it will be best off. When quantum computers hit, the people benefiting the most right now will be the worst off as all their communications from this era are decrypted.

I looked into this a while ago and didn't understand why the efficiency claims were so different, but here's a video of a RO system running https://www.youtube.com/watch?v=2r_T7Bgi3hQ

Some context, the Beijing–Kunming high-speed train takes 10 hours 43 minutes (including 6 intermediate stops) to travel 1,710 mi.

This just makes me wonder about a purpose-built train that allows airport luggage carts.

One argument I found interesting is that the apparent "massive acceleration" in technological progress can largely be explained by the fact that most "productive human years" have actually been lived quite recently. I th

Slime volleyball was one of my favorites! Second only to slime cricket, but finding someone willing to learn how to play cricket wasn’t easy…

As someone who has used wolfram alpha for a long time, I wish they'd just put both. They do on queries like 23000/105000, but not on queries like 23000 = x*105000

There’s a very real possibility it’s a tragedy of the commons. Each individual wants to be near public transit, but they also want a car to supplement weekend trips and such. But once everyone gets a car, ridership falls and the public tran

Is that actually true? Aren’t there several examples of relatively small cavalry forces (of knights) winning against much, much larger forces? Quickly googling: https://en.m.wikipedia.org/wiki/Battle_of_the_Lake_of_Anti

I was really hesitant to use uuids as primary keys because it’s basically worst case clustering performance. Ended up just using 32 bit Unix time followed by 12 random bytes. Not sure why that isn’t an official version.

One weird realization I had is that lava is over three times as dense as water, so if you tired to “swim” in it, you’d basically just sit on top.

Aren’t they orthogonal concepts? Right to work means you can’t be forced into playing Union dues (you have a “right” to scab) and “at will” means the employer can fire anyone at any time for any reason (other than protected classes).

I’d hardly say this is “precedent” for something that’s been done since the beginning of the language. (The Canterbury Tales are generally considered the threshold between old and modern English and they use singular “they”.)

The most egregious broken window fallacy I’ve heard is a vc claiming that cryptocurrency lets you “virtually” transfer energy from areas with low prices to areas with high prices (without power lines!).

I think it should be illegal to ask for a variable tip before a service is substantially completed. Go ahead and charge a fixed gratuity, but prepaying tips is silly.

My favorite example was neurons in your eye that see something and send signals out laterally so when they (after a specific time-delay) meet another neuron that is currently seeing the thing, they combine to trigger a signal that can be di
