Add the following chunk to your existing ISC dhcpd.conf file.

if exists user-class and ( option user-class = "iPXE" ) {
    filename "http://boot.smidsrod.lan/boot.ipxe";
}
else {
    filename "undionly.kpxe";
}

Intro

The plan is to create a pair of executables (ngrok and ngrokd) that are connected with a self-signed SSL cert. Since the client and server executables are paired, you won't be able to use any other ngrok to connect to this ngrokd, and vice versa.

DNS

Add two DNS records: one for the base domain and one for the wildcard domain. For example, if your base domain is domain.com, you'll need a record for that and for *.domain.com.

The introduction to Reactive Programming you've been missing

Icons have been part of applications since ages. Also most websites rely on icons. There were several ways to use them. First we used plain files then image sprites to reduce requests. Nowadays everyone uses icon fonts like font-awesome or glyphicons.

They are infinetly scaleable and styleable with css. The downside is they use pseudo elements for displaying. This is not only difficult to handle but also non-optimal for accessibilty.

A famous CSS-Tricks post brings SVG icons into play. The are also scalable and they behave like normal images. But we also want to have a sprite to not load any images seperatly and kill our servers and our sites performance. The proposed version is to create sprites with grunt or gulp using the symbol-trick. It's basically add every icon to a hidden sprite-image and give every icon an id-property.

Generate a new SSH key:

ssh-keygen -t rsa -C "[email protected]"

Copy the contents of the file ~/.ssh/id_rsa.pub to your SSH keys in your GitHub account settings (https://github.com/settings/keys).

Test SSH key:

	// Octane benchmark suites use this to ensure predictable results.

	Math.random = (function() {

	return function() {
	// Robert Jenkins’ 32 bit integer hash function
	seed = ((seed + 0x7ED55D16) + (seed << 12)) & 0xFFFFFFFF;
	seed = ((seed ^ 0xC761C23C) ^ (seed >>> 19)) & 0xFFFFFFFF;
	seed = ((seed + 0x165667B1) + (seed << 5)) & 0xFFFFFFFF;

	package main
