I installed Mac OS X Server to check it out. Problem was, it blew away my virtual host setup. Here's how I got them back.

OS X Server disables virtual host setup

I've been using the excellent VirtualHostX to set up my virtual hosts on OS X for a while now. It works great for setting up Apache virtual hosts and local domains.

A couple days ago, I decided to install OS X Server. When I enabled the web server portion, it seemingly disabled my virtual hosts and started showing its own page:

Apparently, there's no easy way to uninstall OS X Server.

Falsehoods programmers believe about prices

  1. You can store a price in a floating point variable.
  2. All currencies are subdivided in 1/100th units (like US dollar/cents, euro/eurocents etc.).
  3. All currencies are subdivided in decimal units (like dinar/fils)
  4. All currencies currently in circulation are subdivided in decimal units. (to exclude shillings, pennies) (counter-example: MGA)
  5. All currencies are subdivided. (counter-examples: KRW, COP, JPY... Or subdivisions can be deprecated.)
  6. Prices can't have more precision than the smaller sub-unit of the currency. (e.g. gas prices)
  7. For any currency you can have a price of 1. (ZWL)
  8. Every country has its own currency. (EUR is the best example, but also Franc CFA, etc.)

Fenced code in bullet lists with GitHub-flavoured MarkDown??

Fenced code blocks inside ordered and unordered lists

  1. This is a numbered list.

  2. I'm going to include a fenced code block as part of this bullet:
