git cheat-sheet

The git command-line utility has plenty of inconsistencies http://steveko.wordpress.com/2012/02/24/10-things-i-hate-about-git/

A GUI like http://sourcetreeapp.com is often helpful, but staying on the command line usually quicker. This is a list of the commands I use most frequently, listed by functional category:

Current state

git status list which (unstaged) files have changed

/* 
    This code should be pasted within the files where this function is needed.
    This function will not create any code conflicts.
    
    The function call is similar to printf: ardprintf("Test %d %s", 25, "string");

    To print the '%' character, use '%%'

Intro

Most of us have faced a point when trying to make things work with the Python datetime module where we resort to guess-and-check until the errors go away. datetime is one of those APIs that seems easy to use but requires the developer to have a deep understanding of what things actually mean, as otherwise it is really easy to introduce unexpected bugs given the actual complexity of date and time related issues.

Time Standards

The first concept we need to grasp when working with time is

import asyncore
import logging
import email
from email.header import decode_header
import requests

logger = logging.getLogger(__name__)

Introduction

When applications are running in production, they become black boxes that need to be traced and monitored. One of the simplest, yet main, ways to do so is logging. Logging allows us - at the time we develop our software - to instruct the program to emit information while the system is running that will be useful for us and our sysadmins.
