Git DMZ Flow

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

Activate MS Office 2019/2016 for macOS - Microsoft_Office_2019_VL_Serializer

Office 2019 above

2019-06-03

Note that Office2019 DO NOT support activate via simple copy/paste plist license file which is the simplest way to activate Office 2016. Fortunately, you can also use the VL Serializer tool, just install Office 2019 and Serializer, then run Serializer to activate.
