Command-line arguments in Python show up in sys.argv as a list of strings (so you'll need to import the sys module).

For example, if you want to print all passed command-line arguments:

import sys
print(sys.argv)  # Note the first argument is always the script filename.

Command-line options are sometimes passed by position (e.g. myprogram foo bar) and sometimes by using a "-name value" pair (e.g. myprogram -a foo -b bar).

Welcome!

UPDATE: This list is no longer maintained. I've moved it to its own repo so you can send suggestions as Pull Requests. https://github.com/dideler/bootstrapping/

For feedback or suggestions, please send a tweet (@dideler). Gist comments don't notify me. Pull requests aren't possible with gists (yet), so I don't recommend forking because then I can't easily get the change.

Starring this gist will give me an idea of how many people consider this list useful.

Inspired by this article. Neat tricks for speeding up integer computations.

Note: cin.sync_with_stdio(false); disables synchronous IO and gives you a performance boost. If used, you should only use cin for reading input (don't use both cin and scanf when sync is disabled, for example) or you will get unexpected results.

Multiply by a power of 2

x = x << 1; // x = x * 2

TL;DR

Create a backup:

pg_dumpall > mybackup.sql

Perform the upgrade:

sudo pg_dropcluster 9.4 main --stop

Vertical centering

position: absolute;
top: 50%;
transform: translateY(-50%);

Translate is processed at the end, meaning it is based on the final element height. This means it works with any element, even dynamic heights. Of course it only works on relatively new browsers, but translate is well accepted and on the path to being ubiquitous. The style is also easy to understand and isn't hacky.
