# Fact: javaversion & javamajversion
#
# Purpose:
#   Return the version of the installed Java package in both its full form and
#   just the major release version.
#
# Resolution:
#   Uses the output from the `java -version` command to establish the full
#   version, and then parses that value to return just the major version
#   number. It will return the full javaversion if the major version could not

Git DMZ Flow

I've been asked a few times over the last few months to put together a full write-up of the Git workflow we use at RichRelevance (and at Precog before), since I have referenced it in passing quite a few times in tweets and in person. The workflow is appreciably different from GitFlow and its derivatives, and thus it brings with it a different set of tradeoffs and optimizations. To that end, it would probably be helpful to go over exactly what workflow benefits I find to be beneficial or even necessary.

• Two developers working on independent features must never be blocked by each other
  • No code freeze! Ever! For any reason!
• A developer must be able to base derivative work on another developer's work, without waiting for any third party
• Two developers working on inter-dependent features (or even the same feature) must be able to do so without interference from (or interfering with) any other parties
• Developers must be able to work on multiple features simultaneously, or at lea
