Apache - Maintenance Page

Activate/Deactivate with a file.
Bypass with a custom request header.

With the following Apache Rewrite rule, temporarily redirect all traffic to a maintenance page when a file named maintenance exists at the same level as the DocumentRoot directory. i.e. if your DocumentRoot is /var/www/public_html/ then creating the file /var/www/maintenance would trigger Maintenance mode.

Use something like the ModHeader Chrome browser extension to bypass the maintenance page by setting a X-Maintenance request header with a value of tF0BOCn4z8HgG2Kw (replace this with your own unique passcode string).

How to have local versions of tracked config files in git

This is a fairly common question, and there isn't a One True Answer.

These are the most common techniques:

	# Heavily depends on:
	# libqrencode (fukuchi.org/works/qrencode/)
	# paperkey (jabberwocky.com/software/paperkey/)
	# zbar (zbar.sourceforge.net)

	# Producing the QR codes:
	# Split over 4 codes to ensure the data per image is not too large.
	gpg --export-secret-key KEYIDGOESHERE \| paperkey --output-type raw \| base64 > temp
	split temp -n 4 IMG
	for f in IMG*; do cat $f \| qrencode -o $f.png; done

	const express = require("express");
	const router = express.Router();

	router.get('/', function (req, res) {
	res.send("This is the '/' route in ep_app");
	});

	module.exports = router;

	echo 'export PATH=$HOME/local/bin:$PATH' >> ~/.bashrc
	. ~/.bashrc
	mkdir ~/local
	mkdir ~/node-latest-install
	cd ~/node-latest-install
	curl http://nodejs.org/dist/node-latest.tar.gz \| tar xz --strip-components=1
	./configure --prefix=~/local
	make install # ok, fine, this step probably takes more than 30 seconds...
	curl https://www.npmjs.org/install.sh \| sh
