Automatic update and restart shell scripts for rotc servers

	Automatic updates and restarts for an rotc server
	=================================================

	1) Create an rotc user on your server (home: /home/rotc/)
	2) Checkout rotc using git to /home/rotc/rotc/
	3) Place these two scripts into the /home/rotc/rotc/ folder (and adjust them)
	4) Adjust runme.sh:
	* Make the -srv variable point to your server configuration.
	* If you don't intend to run the script as root remove the sudo's inside.
	If you run as root make sure the runme.sh script isn't editable by anyone else).

Callback maybe

	It threw an exception from hell,
	You ask me, trace wouldn't tell,
	I know JS really well,
	Events are in my way.

	I trade my sleep for a fix,
	time and more time trying tricks,
	I wasn't looking for this,
	Callbacks are in my way.

hacst / .bashrc

Created January 15, 2013 12:30

Custom dash prompt which displays current branch and dirty status in the prompt line when in a git repository folder. Add to .bashrc or another file executed by it like .bash_aliases.

	RS="\033[0m" # reset
	HC="\033[1m" # hicolor
	INV="\033[7m" # inverse background and foreground

	function git_dirty() {
	if [[ $(git diff --shortstat 2> /dev/null \| tail -n1) != "" ]]; then
	echo -n "\[$INV\]*"
	else
	echo -n "\[$HC\]"
	fi

hacst / binasc2asc

Created February 3, 2013 23:02

Since people don't stop writing text as binary ASCII and rewriting the same line over and over again to decode it gets boring real quick remember it as a gist ;) Usage: echo 01000010 00101101 01110011 01101001 01100100 01100101 | ./binasc2asc.py

	#!/usr/bin/env python
	import sys
	print "".join([chr(int(c,2)) for c in sys.stdin.read().strip().split()])

hacst / main.cpp

Created May 25, 2013 19:44

Experimentation with typesafe indices for https://plus.google.com/u/0/103771295878903986513/posts/CiwQXgwHbJ1 Basically the gist of what I wanted from a strongly typedef'd size_t. This example only implements the operators I needed and already took quite a bit of code that might (will ;) ) contain bugs and unexpected behavior. For my application…

	#include <vector>
	#include <cstddef>

	template<typename Tag>
	class TypesafeIndex
	{
	public:
	inline TypesafeIndex() : m_i() {};
	inline explicit TypesafeIndex(const size_t a_value) : m_i(a_value) {};

hacst / gist:2b047b19e2eb7b053610

Created October 2, 2014 20:27

MetaParams::typeCheckedFromSettings specialization for size_t in case I end up needing it one day (Mumble code)

	template <>
	size_t MetaParams::typeCheckedFromSettings(const QString &name, const size_t &defaultValue) {
	QVariant cfgVariable = qsSettings->value(name, defaultValue);

	bool ok = false;
	qulonglong value = cfgVariable.toULongLong(ok);
	if (!ok \|\| value > std::numeric_limits<size_t>::max()) {
	qCritical() << "Configuration variable" << name << "is of invalid format. Set to default value of" << defaultValue << ".";
	return defaultValue;
	}

hacst / line-dasharray-test.html
