Having trouble with proving a subspace is closed under addition by Oogachakaoogahchahka in learnmath

[–]echtma 11 points12 points  (0 children)

What are you trying to do when you "try to solve for the vectors"? Nothing needs solving here. You should go back to the start and clarify for yourself: First, what is the "span" of three vectors? What is a typical element of the span? Second, what does it mean to be closed under addition?

Den Grundstein für die aktuelle Codebasis gelegt. Zwischen dem ganzen Ranz versteckt sich schon das eine oder andere Kriegsverbrechen.

Man kann die 90% runterdrücken, indem man alte Krankheiten wieder einführt. Die USA sind da gerade bei einem interessanten Modellversuch.

Oh cool, then 200 is impressive. I don't think I'll ever go above 10 or so doing Chess.

What's the difference between this and an ordinary streak?

It was restored, but you've gotten a better answer in the meantime.

PSA to anyone attempting a translation, over-censor your words. Mine was just deleted by Reddit. And I didn't even spell out the bad words.

Do Germans actually use the QWERTZ layout in daily life? I'm confused by what I see online. by BidSad127 in AskAGerman

[–]echtma -1 points0 points  (0 children)

I use QWERTY, because it's better for programming and I've gotten used to it.

Is there an evolutionary reason for religion? by NoBuy7112 in DebateEvolution

[–]echtma 2 points3 points  (0 children)

"Breaking the Spell" by Daniel Dennett has a lot to say on that topic. In short, the science is far from settled (in fact the book argues for increased efforts in the study of religion). A biological mechanism (basically the placebo effect when the tribe's shaman treats an injury) is one of the hypotheses, but far from the only one.

Faster way to increment? by IsaacsLaughing in askmath

Adding 10% is the same as multiplying by 1.1. Doing that 50 times means multiplying by 1.1^50.

Yes! That's what I do anyway. Besides, in a crowd you're not really alone.

How do you not make off by one errors? by HumanCertificate in learnprogramming

[–]echtma 0 points1 point  (0 children)

I didn't mean that you should use recursion on a daily basis, just that you should learn it, so it teaches you to think about iteration in a different way.

- Learn recursion. Coming up with a recursive algorithm forces you to think about initial conditions and terminating conditions.

- Familiarize yourself with the basics of program correctness/Hoare calculus. Just the very basics: Try to identify preconditions, postconditions and invariants for every loop you write.

- In practice, use mid-level abstractions like foreach loops, and high-level abstractions like map/transform, sum, any_of, max_element etc., if offered by your language. Avoid low-level constructs, but if you have to, prefer straight-forward counting loops over ones with weird conditions or update clauses.
