[Links of the day] 13/06/2016 : Geometric Algorithms, Logical Clock are easy & distributed system testing

• Geometric Algorithm : Princeton algorithms and data structures lecture. Provide an excellent overview of the geometric algorithms out there and why they are important. 
• Why Logical Clocks are Easy : well not really but still , AMC queue article on the ever recurrent issue of time in distributed systems. 
• Distributed Systems Testing : When you cannot find good article on a subject, ask on twitter. The result is a good list of distributed system testing papers.
