You can display code with markdown. You just can't put executable code in a post (for obvious reasons).
Markdown appears to be a standard for discussing code on GitHub. This is an if/then statement fenced with mark down:
/********
* A sample if then statement
********/
If (this) {
do that;
]
You forgot to put the link to the CDN you referenced in the talk about SVG fonts.
There is a huge need for developers and programmers on HIVE.
