Here's a PDF with the slides for my ICOPS 2017 talk entitled Validation and benchmarking of two particle-in-cell codes for a glow discharge (presentation "TH 1.1-3" in the conference program).
A follow-up comment to the talk was that "a code with known flaws is much better than a code with unknown flaws". I think that summarizes the topic of validation nicely. The purpose of validation isn't necessarily to pass with flying colors, but to learn for what cases to trust a code, and for which cases NOT to trust a code. If you find issues that are easy to fix, great! But even if you find issues that are not possible to fix immediately (or ever), validation can still be worthwhile.

I gave two talks at the IEEE International Conference on Plasma Science (ICOPS) this morning in Atlantic City. The first one was called Particle-in-cell simulation of anomalous transport in a Penning discharge (Carlsson, Kaganovich, Raitses, Powis, Smolyakov and Romadanov). It was the first time I used Google Slides for a talk. Worked like a charm and I'm pretty happy with it, even if I'm uncomfortable with having the source files for my slides in the Google cloud and not in a git repo of my choosing. I think ICOPS will make all talks publicly available online, but I think they expect PPT or PDF slides, hence the above link to the original version of the talk, if something gets lost in translation.
