Since Django 1.10 you can simply use get_random_secret_key in django.core.management.utils. This will not work: if python3: print (SECRET_KEY) else: print SECRET_KEY because it's a…

No, that's 1.11 (a LTS release)

"Monad" in English and "Monade" in German are the same, they can both mean the functional programming concept or the philosophical concept. You can just ignore the philosophical co…

It's Python - you can do a lot of meta-programming with it, though unlike Lisp and Mathematica there's a division between expressions and statements.

Earlier version was wrong https://cstheory.stackexchange.com/questions/1064/polynomial... , I doubt the current version has any substance.

The algorithm is only of theoretical interest, the situation is similar to primality testing. In practice programs such as nauty are good enough.

I set up an alarm clock for "detox" every day. I turn off my computer, silence the mobile phone and do nothing but read for hour or two. Resist any temptation to check email. I've …

I'd like to add this scenario actually happened during the Cold War. Soviets were reusing one time pads and the US army decrypted some of the messages, among other things this lead…

Alias often used commands, I have g = git, sl = ls (common typo). Git: set up aliases. I can type "g co = git checkout", "g st = git status". Git configuration: pull.ff only (then …

Yes, ff-only will fail. If C,D are independent and simple, I would go ahead and rebase, otherwise do a proper merge. Remember you can play a lot with git; if you are not sure how i…

I recommend git config --global pull.ff only instead, then you can use "git pull" without worries. Or, git pull --ff-only

I see, thanks.

What is the difference between x ?: y and x || y?

Unary representation is useless when speaking about complexity in number theory. If you take a number N given in unary, convert it to binary and do trial division up to the square …

Flux https://justgetflux.com/ or redshift http://jonls.dk/redshift/ . Try setting it to the smallest temperature possible for 30 minutes and then turn it off to see the difference.…

Note it's not a pull request; it's an issue in the tracker. Had it been a prepared patch, I would have more sympathy towards the reporter.

If you ask Mathematica whether x^n + y^n = z^n has solutions for n>2 and x,y,z>0, the system will simplify it to "False", displaying knowledge of Fermat's last theorem. This is tak…

That's exactly the point of monads - see http://homepages.inf.ed.ac.uk/wadler/papers/marktoberdorf/ba... . Such a system is still pure, btw.

When I write a program, I don't want it to be just correct (true); I want it to be _provably_ correct; I want to be able to be convinced that it is correct, at least in principle, …

I'd like to add x^y is also used other contexts - e.g. for cardinal numbers and ordinal numbers.
