Hey, guys! There was a pretty big delay between issues due to my journey from Barnaul to Moscow->Kaluga->St. Petersburg (current)->Moscow->Barnaul, but I hope this will not happen again anytime soon. At least, not in next 3 months :)

So, enjoy the issue! Today we have several articles on tweaks for a test suite, couple posts on new (not so but anyway) languages Crystal and Nim and several nice tools to check out.

I hope you’ll like it!
