janosgyerik / post-receive
Last active November 2, 2016 06:57
A post-receive hook that runs a script if changes were pushed to a specific branch. (Hook scripts are in the hooks/ directory of a Git repository, and must be executable.)
#!/bin/sh
# 1. Create symlinks to the real upgrade scripts for each branch, for example:
# ./upgrade-beta.sh # will only be called when "beta" branch is updated
# ./upgrade-prod.sh # will only be called when "prod" branch is updated
#
# 2. Put these symlinks in the repository root, NOT in the hooks/ directory
# the post-receive hook receives parameters on stdin

Last active December 17, 2015 17:09
Collecting ideas for a presentation about how awesome is Vim

Cool things other editors can't do or not easily, but easy in vim.

Create a macro to replace all occurences of:

{% url package.module.method %}

with:

{% url 'package.module.method' %}

janosgyerik / rearrange.cpp
Created March 1, 2013 08:12
A program to print all possible arrangements of `n` numbers. It accepts `n` as a command line parameter. Be careful, as there are `n!` possible permutations. With `n=10` or greater the program will be extremely slow.
#include <stdio.h>
#include <stdlib.h>
void rearrange(int *numbers, int index, int num) {
int tmp;
for (int i = index; i < num; ++i) {
tmp = numbers[index];
numbers[index] = numbers[i];
numbers[i] = tmp;
rearrange(numbers, index + 1, num);
