Emscripten as a linker for Zig and C

This shows how to build a nontrivial program using Zig+Emscripten or C+Emscripten. In both cases Emscripten is only used as a linker, that is the frontend is either zig or clang.

"Nontrivial" here means the program uses interesting Emscripten features:

Asyncify
Full GLES3 support
GLFW3 support

Setting up geth as a service under systemd Fedora 27

Prerequisite: dnf install golang

Create user geth with useradd
As user geth fast sync the blockchain, geth --fast --cache 1024
Manually run geth --rpc as user geth and watch to see that the blockchain continues to sync properly
Install the geth.service file (also in this gist) in /usr/lib/systemd/system/
Make a symlink from /etc/systemd/system/multi-user.target.wants/geth.service to /usr/lib/systemd/system/geth.service
systemctl enable geth followed by systemctl start geth

	If you want to disable zoom on mobile use the following meta tag:
	<meta name="viewport" content="width=device-width, height=device-height, initial-scale=1, minimum-scale=1, maximum-scale=1, user-scalable=no">

	This will archieve the following:
	- user can not zoom in or zoom out
	- the page will always have a scale factor of 1
	- as an added "bonus" this will get rid of the browser bounce, when the user reaches the end of the page while scrolling.

	Use this technique with caution, because the accessibility of your page will suffer drastically.
	No zooming means that your page might not be visible on some devices and that users have difficulty with accessing your website.
