How to generate and apply patches with git?

It sometimes happen you need change code on a machine from which you cannot push to the repo. You’re ready to copy/paste what diff outputs to your local working copy.

You think there must be a better way to proceed and you’re right. It’s a simple 2 steps process:

1. Generate the patch:

git diff > some-changes.patch

#!/bin/bash
# bash generate random alphanumeric string
#

# bash generate random 32 character alphanumeric string (upper and lowercase) and 
NEW_UUID=$(cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 32 | head -n 1)

# bash generate random 32 character alphanumeric string (lowercase only)
cat /dev/urandom | tr -dc 'a-z0-9' | fold -w 32 | head -n 1

A quick-start guide for using gnuplot for in-terminal plotting

Sometimes it is really nice to just take a quick look at some data. However, when working on remote computers, it is a bit of a burden to move data files to a local computer to create a plot in something like R. One solution is to use gnuplot and make a quick plot that is rendered in the terminal. It isn't very pretty by default, but it gets the job done quickly and easily. There are also advanced gnuplot capabilities that aren't covered here at all.

gnuplot has it's own internal syntax that can be fed in as a script, which I won't get into. Here is the very simplified gnuplot code we'll be using:

set terminal dumb size 120, 30; set autoscale; plot '-' using 1:3 with lines notitle

Let's break this down:

alobato

#!/bin/sh

# Quick start-stop-daemon example, derived from Debian /etc/init.d/ssh
set -e

# Must be a valid filename
NAME=foo
PIDFILE=/var/run/$NAME.pid
#This is the command to be run, give the full pathname
DAEMON=/usr/local/bin/bar
