Here are two of my talks that were recorded and are available online.
Why Is Random Testing Effective for Partition Tolerance Bugs?
Nasumično testiranje distribuiranih sustava
The next talk was given in April 2018 at the Mathematical Logic and Foundations of Mathematics Seminar in Zagreb, and it is about applying combinatorial techniques in testing distributed systems. The talk is in Croatian.
(For some reason I’m wearing the same T-shirt in both talks. )
