 During ElixirConfEu in Barcelona, I learned about Property Testing. It looks pretty neat and it got me interested. Basics sound quite easy but there’s more than meets the eye and I’ve been reading/listening about it for a while.
 As I don’t feel comfortable enough to do a deep dive into the topic I will do an introduction to it. After I get a deeper understanding with some “real life” examples (or maybe doing them myself) I will write a follow-up.

 While using EntityFramework in my integration tests (which is a separate topic ;) ) I discovered quite interesting thing. I guess this may be obvious to some, but I learned Entity "the hard way" jumping into an app with Entity already in place and had to adapt - this was my first app with a database by the way.
 
 So if you add entities to your context I'm used to adding all entities to context, so the code would look like

 using (var ctx = new Context())
 {

 After ElixirConfEu I decided to try PureScript. Partly for yet another frontend try, party because it looked interesting and partly because I wanted a little break with something way different and new.

 While a back ago I did a little test. I read the <a href="https://leanpub.com/deliberatevim" target="_blank" rel="noopener">Deliberate Vim</a> book, did the exercises and decided to go full Vim. So I installed <a href="https://www.viemu.com/">ViEmu</a> to my VisualStudio 2015. Aaaand had a few struggles. Some shortcuts conflicts that I had to solve manually and still it wasn't so convenient to use.
