How to exit from Python without traceback?
...
You are presumably encountering an exception and the program is exiting because of this (with a traceback). The first thing to do therefore is to catch that exception, before exiting cleanly (maybe with a message, example given).
Try something like this in your main r...
When and why will a compiler initialise memory to 0xCD, 0xDD, etc. on malloc/free/new/delete?

Pelican 3.3 pelican-quickstart error “ValueError: unknown locale: UTF-8”
...ile:
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
There is an outstanding bug report related to this issue. It appears that Python makes some assumptions about the format of locale names that aren't universally valid. Explicitly setting these environment vars is basically just a workaround...

A collections.deque is optimized for pulling and pushing on both ends. They even have a dedicated rotate() method.
from collections import deque
items = deque([1, 2])
items.append(3) # deque == [1, 2, 3]
items.rotate(1) # The deque is now: [3, 1, 2]

What is the use of “ref” for reference-type variables in C#?
I understand that if I pass a value-type ( int , struct , etc.) as a parameter (without the ref keyword), a copy of that variable is passed to the method, but if I use the ref keyword a reference to that variable is passed, not a new one.

date format yyyy-MM-ddTHH:mm:ssZ
...
The accepted answer says to use format specifier "s" and append a Z on the end for UTC dates. That's all good and fine if you don't need the milliseconds, but if you want the milliseconds you have to use "o" like this answer shows. With "o", the milliseconds show up by defaul...
Big O of JavaScript arrays
Arrays in JavaScript are very easy to modify by adding and removing items. It somewhat masks the fact that most languages arrays are fixed-size, and require complex operations to resize. It seems that JavaScript makes it easy to write poorly performing array code. This leads to the question:
