Remote working with opensource tools


We’re living times where the level of information created and consumed is too much to be procesed in a simple way. Each company has it’s own solutions or standars how the manage this problem and other type of entities like universities don’t have a unified approad.

The idea behind this post it’s to try to create a simple set of tools as a base for any company or entity looking forward to have a minimal setup for communication.

All this tools are opensource and, in some cases like bedework used by universities over the world.

The rules follow here are:

  • A tool must be opensource
  • Data must be encrypted
  • It must provide self hosted intallation

If you’re a small company, a community or a learning institute trying to organize your communication this may help to do it.

The list of tools to use will be:


  • A server
  • A domain


Simplify networking complexity while designing, deploying, and running applications.
