GitHub Commit Storytelling: Now or Later

Introducing inefficiencies into RavenDB, on purpose

The administrators on the server noted the high I/O and that a single thread was constantly busy and decided that this is likely a hung thread.

Trust instead of Threats

According to Dr. Gary McGraw’s ground breaking work on software security, up to half of security mistakes are made in design rather than in coding. For the last 10 years we’ve been told that we are supposed to do this through threat modeling. What else can we do to include security in application design?
