_I sometimes get asked for references and tools (free and/or open source oriented) and I decided to compile here the ones I use the most, which I highly recommend for frequent use (so very personal selection)._  
  
_Considering that this is "work in progress" for the moment, I'm open to any suggestion._  
  
_Good reading !
