What people use nowadays as a database with ejabberd? I was a user of a ejabberd service 20+ years ago and mnesia (which at that time was the default option) was the reason for frequent downtimes. As a user I don’t know details but ejabberd+mnesia didn’t look robust.

Pgsql for me.

I think the baseball stat OPS (on base percentage plus slugging) fits this mold of "improper linear model" quite well. There are much more robust measures of hitting now, but OPS works better than it ought.

This is one of those pieces of software that I've basically never run into issues with. XMPP itself is rather a moving target, so reviewing which modules are enabled from time to time is necessary, but other than that administering it is a breeze.

Toilets (1.5 - 2.5 g per flush), then showers (2.5 g per minute), then clothes washer (about 15 - 20 g per load) are the big 3.

If you do 1 load of laundry per person per day (which is absurd), then the clothes washer cant' be even 1/4 of the over 80 gallons per person per day TFA claims.

I'm gonna add another perspective. I was placed, and excelled, in moderately advanced math courses from 3rd grade on. Mostly 'A's through 11th grade precalc (taken because of the one major hiccup, placing only in the second most rigorous track when I entered high school). I ended that year feeling pretty good, with a superior SAT score bagged, high hopes for National Merit, etc.

Then came senior year. AP Calculus was a sh/*tshow, because of a confluence of factors: dealing with parents divorcing, social isolation, dysphoria. I hit a wall, and got my only quarterly D, ever.

The, "if you get left behind, that's on you, because we're not holding up the bright kids," mentality was catastrophic for me - and also completely inapplicable, because I WAS one of the bright kids! I needed help, and focus. I retook the course in college and got the highest grade in the class, so I confirmed that I was not the problem; unfortunately, though, the damage had been done. I'd chosen a major in the humnities, and had only taken that course as an elective, to prove to myself that I could manage the subject. You would never know that I'd been on-track for a technical career.

So, I don't buy that America/Sweden/et al. are full of hopeless demi-students. I was deemed one, and it wasn't true, but the simple perception was devastating. I think there is a larger, overarching deficit of support for students, probably some combination of home life, class structure, and pedagogical incentives. If "no child left behind" is anathema in these circles, the "full speed ahead" approach is not much better.

In the school district I live in, they eliminated all gifted programs and honors courses (they do still allow you to accelerate in math in HS for now, but I'm sure that will be gone soon too), so a decent chance you might not have taken Calculus in HS. Problem solved I guess?

It's like this in the US (or rather, it was 20 years ago. But I suspect it is now worse anyway)

Teachers in my county were heavily discouraged from failing anyone, because pass rate became a target instead of a metric. They couldn't even give a 0 for an assignment that was never turned in without multiple meetings with the student and approval from an administrator.

The net result was classes always proceeded at the rate of the slowest kid in class. Good for the slow kids (that cared), universally bad for everyone else who didn't want to be bored out of their minds. The divide was super apparent between the normal level and honors level classes.

I don't know what the right answer is, but there was an insane amount of effort spent on kids who didn't care, whose parents didn't care, who hadn't cared since elementary school, and always ended up dropping out as soon as they hit 18. No differentiation between them, and the ones who really did give a shit and were just a little slow (usually because of a bad home life).

It's hard to avoid leaving someone behind when they've already left themselves behind.

I'm sure it's regional, but my oldest kid started school in SoCal 13 years ago, and it is definitely worse. Nearly every bad decision gets doubled-down on and the good ones seem to lack follow-through. I spent almost a decade trying to improve things and have given up; my youngest goes to private school now.

I don't know a huge amount about video encoding, but I presume this is one of those libraries outlined in xkcd 2347[0]?

Pretty much.

It also was originally authored by the same person who did lzexe, tcc, qemu, and the current leader for the large text compression benchmark.

Oh, and for most of the 2010's there was a fork due to interpersonal issues on the team.

Yeah I never really understood why people complain about tar; 99% of what you need from it is just `tar -xvf blah.tar.gz`.

You for got the -z (or -a with a recent gnutar).

Talking about wasteful. There 16,000 golf courses that use 312,000 gallons a day[1]. Thats 1.82 trillion gallons annually. Only 28 million people play golf course on a course. Google's MAU is 90%+ of US population, beef or milk consumptions i would guess that 90% of population consumes it at least once a month. We're focusing on things that everyone uses but the things that less than 10% of the populations partake in. Why do we have golf courses in arid regions that have severe water shortages? Before places like LA county spends $8 billion on a toilet to tap system[2], maybe shut down the golf courses first.

I'm mildly surprised that almost 10% of the US golfs. That makes the 0.3% of water usage from TFA seem less bad.

I'm somewhat astonished at the per-capita household use of water per day. I assume it must mostly be for watering lawns?

We have a swimming pool that leaks (we were quoted $125k to fix it since the deck will need replacing, and with interest rates being what they are, borrowing to fix it would be rather painful), and we use only 51gal/person/day at our home. I estimate that if fixing the pool would save another 10.
