Another fat guy here. I haven't taken any of these drugs, but I stopped eating processed food (or anything with added sugar), avoided late night snacks, and lost around 30 pounds in 8 months as a result. I had the fatigue and such early in the process, but it sorted itself out eventually. The most important thing I recognized was that if I avoided eating late at night, I didn't feel awful waking up in the morning. I'm embarrassed to say it took more than a year to change my behavior, despite my clear understanding of the harm of snacking all the time.

Does Restic do encryption well now? When I tried it years ago you had to type the password on the command line, and there was no interest in adding GnuPG support.

The white supremacist ideology is strong with this one.

What is UBO?

They were using "cognitive ability" back in the 1980s when I was in high school taking the SAT.

> What percentage of HN parents have tracking on their kids phone? > > All of them.

All phones have "tracking" in that they're on a cellular network, so they can be tracked by a cell phone company. My son's phone was stolen at his school recently, but we had no way to recover it. What tracking software do people use on their kids phone? Perhaps I can use it to recover the phone if the next one gets stolen. Apparently since I'm the only parent here who doesn't have tracking for his kids, I want to make your claim true.

> This is a result of government strangling the construction market and nothing to do with collusion or hidden pricing.

Actually, many apartments near prestigious UC schools (Berkeley, UCLA) are priced to be affordable for two students per bedroom. This is how some undergraduate students have been renting for decades, from my own personal observations. A $7200/month 3 bedroom can house 6 students in bunk beds. So at $1200/month per student, this is more than affordable for their upper middle class parents.

Can you point to any one thing he said which no one else has said before? Maybe an insightful comment to help understand his "relevant perspective"?

He got a degree from MIT, did a year at Jane Street, but is unable to keep basic financial records??? This doesn't make sense to me, and seems like obvious fraud.

You can use both, to an extent. My most recent example: The documentation for GNU troff (groff) in Debian is incomplete-- the man page for eqn(1) includes the GNU extensions mostly, but not the basics. So I downloaded the OpenBSD manpages which includes complete documentation for eqn(7).

https://ftp.openbsd.org/pub/OpenBSD/snapshots/amd64/man72.tg...

Good documentation is a killer feature, in my opinion. It's nice they provide it all in one tar ball.

To be fair, you can cite a Wikipedia page along with the last revision date. And the complete revision history is available, I believe. I would expect researchers to include revision dates with any Wikipedia citation.

This is exactly the problem. And we're all suffering for it.

> In primary school for example, we learn maths by memorising times tables and solving thousands of basic arithmetic problems. This was important in a time before calculators...

I used to think like you on this point, until I taught students who were brought up using calculators instead of memorizing multiplication tables, etc. It turns out that many of them could not figure out how to use calculators when needed--they didn't know what to enter because they were rarely required to do any mental math. It's really important for elementary school students to count out loud (including by 2's, 3's, etc.), and count backwards, and memorize multiplication tables, etc., so they are comfortable and confident doing basic arithmetic. Calculators are for people who already understand how to do arithmetic.

> Now I don't feel like a well-rounded adult, and I wish I spent more time when I was younger on music and humanities.

Easy remedy. Learn an instrument. Find someone local to take weekly lessons, and practice several hours a week. If you never did this before I think you will be overjoyed by how well you play with consistent practice.

Since I agreed to this without bothering to read it, do the other services (Venmo, CashApp, Zelle, etc.) have similar provisions anyone knows of? (Apologies in advance for being too lazy to read the agreements myself. And yes, I'm a horrible person for not bothering to read them.)

That graph is misleading. The 1980s level of sugar intake is already way, way higher than sugar intake of prior generations of humans. For example, if you eat 3 times as much sugar as prior generations, reducing the intake to only 2 times as much, which is still too high, means you still get diabetes and liver disease. I'm impressed that people are so easily fooled by this one.

I think Jonathan Boccara's talk, "105 STL Algorithms in Less Than an Hour" ( https://www.youtube.com/watch?v=2olsGf6JIkU ), gives a nice overview of the <algorithm> library. Also, the examples on the reference pages (usually near the bottom) at cppreference.com are usually pretty good. For example: Here's how to create a pseudo random number generator using the Mersenne Twister engine.

  std::mt19937 e; // Mersenne Twister engine
  std::uniform_int_distribution<int> u(0,99999); // uniform ints 0 to 99999, inclusive
  auto rng = std::bind(u,e); // so rng() retuns the next random number

And filling a vector with random numbers could look like this:

  std::vector<int> nums(1000);
  std::generate(nums.begin(), nums.end(), rng);

This last line can be written in C++20 more simply like this:

  std::ranges::generate(nums,rng);

Submissions are moderated, but depending on the field, anything reasonable-looking may be accepted. For example, there is more than one "proof" of the Riemann Hypothesis in the arXiv. But the moderation system certainly keeps out spam.

Edit: Here's a proof of the Riemann hypothesis submitted just last week: https://arxiv.org/pdf/2209.01890.pdf You can have a little fun exploring "proofs" of famous theorems on the arXiv over the years.

> Even just the git has many releases during Debian Stable...

It just so happens the software you mentioned, git, is in stable backports, so it is updated frequently. Regardless, I've been on Debian stable since 2007, and running "bleeding edge" stuff is trivial, depending on your desired workflow. (For example, I just install Debian testing packages in a schroot.) I used to bounce from distribution to distribution in the old days (Red Hat, Mandrake, Slackware, Gentoo, etc.) but once I found Debian Stable I could concentrate on getting work done.

You don't have to read them linearly. Volume 2 (Seminumerical Algorithms) starts with an awesome discussion of random number sequences. I think all programmers who use random number generators could benefit from reading it. You can just pick and choose other topics throughout the series.

Also, used copies can be really cheap. Some of the volumes in my back up set were just $20 each, and in excellent condition. Apparently lots of people buy the books and never read them :)

These acronyms are destroying my will to live.

> I believe he should have named the agency.

I disagree. (1) There is evidence that his company may profit from the redesign, and (2) he risks being sued for even the slightest mischaracterization in his blog, which requires tens of thousands to defend (at least). I don't see the point in risking the family business over this. Both parties learned a lesson. Perhaps the WebAgency will decide never to have hourly clients again.

I thought engineers use 22/7?

I took Algebra 1 in 9th grade, and Algebra 2 and Geometry in the 10th grade. The 9th graders in my Algebra 2 class (who took Algebra 1 in 8th grade) had holes in their algebra background because middle school algebra is taught at a lower level than high school algebra. But I wasn't behind, for I took AP Calculus in 11th grade successfully because of a strong foundation from high school level algebra classes. However, I'm struggling with placement choices for own children as we speak.

Same here. Long ago I tried to generate an encryption key by flipping a coin. After getting a rhythm and flipping heads 20 consecutive times I gave up.

> As a student witnessing the amount of cheating going on, I was always surprised about the noise raised by teachers on it: I always felt that my score was my own, and didn't care about comparing against others.

Years ago a few students in my class were complaining about cheaters. They were frustrated, and one even accused me of missing "obvious" cheaters. It was embarrassing for me, and brought down morale in the class. I have policed exams more aggressively ever since.

In another class, I caught a cheater during an exam (Calculus 2 or 3), and one of his classmates e-mailed thanking me, noting the student cheated his way through the prerequisite class the prior semester.

This stuff really matters.

> I still wonder sometimes whether an infinite composition of continuous functions has to be continuous (limit of a sequence) ...

No, as you expected. Take f(x) = x^2 on [0,1]. Then f(f(f(...f(x))) converges to g(x) = { 0, if 0 <= x < 1; 1, if x=1 }

Step 3: Update the TODO list

Step 4: Go to Step 2.

> I'm not convinced that cycling is especially dangerous and my experience is that I've inevitably put my hands out when falling, so I think that gloves should be the first part of PPE recommended for cyclists.

Around 15 years ago I fractured my right arm doing the same. There were no scratches on my hands--I used my right hand to stop the fall primarily and the force was just too much. However, if I had hit my head, which was not unlikely in that particular fall, a fractured skull would have been much worse.

Ironically, I used to ride without a helmet, but only started when I moved to Los Angeles and had a few near-misses. Drivers here have a different idea about sharing the road than elsewhere. Biking fast through an intersection when a car traveling in the opposite direction is waiting to turn left is a recipe for disaster--they never want to wait, so I like to yield even when I have the right of way.

Even well-maintained streets can get potholes, especially after huge weather swings. I once hit a pothole while biking and somersaulted over the handlebars. I landed on my back, but a slightly smaller rotation would have me in the hospital, or worse.
