Possibly. It was basically the native language of Unisys A-series mainframes and I guess those are still around in some form or other.
Ocean currents + cost-effectiveness, according to Ian Morris.

By his telling, Chinese bureaucrats buried the knowledge of large fleets because it was a more expensive way to project power than simply going over land.

Huh, self-aware HN. Don't see that very often.

Threw me down this rabbit hole: https://en.wikipedia.org/wiki/Datalog

Looks like Flix is in a galaxy of languages implementing Datalog, a variant of (or somehow related to) Prolog. I guess Flix is Turing-complete while Datalog is not?

I used the swagger interface a few months ago to download my resting heart rate over a three-year period, and it was interesting.

Waddya mean, your kids? I learned that as a teenager myself in the 1930s, after an article in Scientific American.

Re:Why I left Google: work-life balance on Tuesday May 10, 2022 @10:13PM (#31335095)
Honestly, "left Google for 40-person startup for work-life balance reasons" brought me up short.
My technique so far has been to join interesting-looking instances and read the local stream. People who say smart things I follow. At some point I'll coalesce my follows into one account, I guess. I think continuing to do that, along with following boosted toot authors if they look smart/interesting, will eventually generate a good list of follows.

I have long thought writing law is a LOT like writing code. When you actually look at modern laws, they're basically legal patch files.

Re:Goldman Sachs invests $250M in compressed air energy storage on Wednesday January 12, 2022 @05:45PM (#29913805)
"Looked the temp gradients up, after 50ft, temp of the earth is 50F, and raises one degree F every 60ft." (So, at 300 feet, 54 degrees; at 500, 57.5 degrees.)

"...but other parts of the mine was very cold you made sure you had plenty to ware it depended where you worked"

(https://www.quora.com/Are-coal-mines-cold/answer/Keith-Scott...)

"Underground mines maintain a constant temperature, around 55 degrees Fahrenheit."

«The temperature on average is in the 50s, but you still sweat an enormous amount when you start laboring.“ - Alan Bates, working in the coal mines of Letcher County, Kentucky.»

Yes, a 4000m gold mine is hot. I doubt that's where they're storing their compressed air.

Re:Goldman Sachs invests $250M in compressed air energy storage on Wednesday January 12, 2022 @11:00AM (#29908254)
I'm guessing not. Earth's heat is way lower down. Think of a cave: always cold. I think what's going on is they're taking the heat out and storing it more efficiently than just dumping it down the ground, where (1) it would leak away, representing energy loss, and (2) as it leaks away, the air would lose pressure. (It would leak away b/c it's harder to insulate an entire mine, basically.) So, they pull it out ahead of time and put it back in when they decompress the air (which I think would add pressure back in due to heating a gas and maybe reduce problems caused by super-chilling other plant hardware? Anyway, seems fitting to add back what you took out if you're shooting for a closed system.)

A corollary-ish observation of my own:

   * If coders could write useful documentation (starting w/inline comments) they probably wouldn't be coders.

Been using it for years and years, and I started same as you, with some basic outlining. Now it's my primary work organizer/brainstorming/documenting tool (I generate html from it for other folks to read, although I'll occasionally drop plain text somewhere).

None of your business. Go away. You have mail.

I have a blog, which is

(a) Basically just a bunch of glorified retweets, but (b) Free of the moronic 280-character limit, and (c) Immune to Twitter's moronic "jail" algorithm (all I have to do is delete the IFTTT tweet, not my "blog post")

And I think that's fine. And, yes, I do have opinions on the moronicity of Twitter, how did you know?
