Founder and Software Engineering Consultant @CS Kerckhove
Safety expert, interested in anything that's necessary to make a system work robustly.

That could be programming languages, formal methods, testing or DevOps.
Property testing has been around for two decades, and the design space is rapidly being explored, but keeping up with these developments has not been easy.

This talk gives a thorough overview of the different libraries and explores their tradeoffs.

Libraries discussed in this talk include QuickCheck, Hedgehog, Validity, Quickspec, Easyspec, speculate, leanspec and smallcheck.
Works at JetBrains (where no one knows exactly what he is doing) and teaches programming at the new department of mathematics and computer science at Saint Petersburg University.

Over the years in higher education, he taught many different courses in computer science and mathematics. He translated and edited books on Haskell and related topics for DMK Press.

Since 2007, Vitaly has been interested in Haskell, now he is a member of the Haskell Language Committee and the GHC (Glasgow Haskell Compiler) Steering Committee. Author of Haskell in Depth (Manning Publications, available in MEAP Early Access Program).
Dependent typing has been buzzing around in the functional programming community for a couple of decades.

While it provides much more control over our programs and extends the expressivity of type systems to much higher levels, it makes programming much more brain consuming. In most cases, it is quite difficult to persuade the compiler that we are doing the right thing and get our program compiled.

In this talk, Vitaly will give many examples of dependent typing in several languages and explain why he's not as excited as a bunch of dependent typing advocates.


More speakers and talks to be announced soon.
