Roots in Open Source
@ablythe
Open Source for Infrastructure
• What I am not saying:– Open Source for all software– Open Source only (many of these
suites/companies have Enterprise options).• I am saying:– When the core is open source you get "Linus' Law”– Since you are a developer, you can crack the code
and just fix it.
