Installation Requirements
You will need a computer. Options include:

A Normal Computer: This is strongly recommended. Many installs use a VM in EC2. Phabricator installs properly and works well on a normal computer.
A Shared Host: This may work, but is not recommended. Many shared hosting environments have restrictions which prevent some of Phabricator's features from working. Consider using a normal computer instead.
A SAN Appliance, Network Router, Gaming Console, Raspberry Pi, etc.: Although you may be able to install Phabricator on specialized hardware, it is unlikely to work well and will be difficult for us to support. Strongly consider using a normal computer instead.
A Toaster, Car, Firearm, Thermostat, etc.: Yes, many modern devices now have embedded computing capability. We live in interesting times. However, you should not install Phabricator on these devices. Instead, install it on a normal computer.

Phabricator, an open source software engineering platform
Phabricator is a collection of open source web applications that help software companies build better software.

Code review can be a bit of a recipe for drama. There was a large-ish amount of drama in a close project quite recently that stemmed from patch review, and it got me thinking about how we handle this in free software.

In free software code review, along with other practices that we call “agile practices” (such as continuous integration, unit testing, behavior driven design, test driven development) is a relatively new thing in some projects, especially those on the desktop stack.
