May update for April

I was a bit quiet during April and not announcing both the two blog posts I wrote, a German post on systemic evolution, and an English post on classical approaches to borrowing detection in historical linguistics. This is mostly due to the fact that we were all very busy in April, as our CALC project organized its first conference, a workshop on Old Chinese and Friend, which went rather well, with many fruitful discussions. Although May will also be a busy month, I hope to be able to provide updates earlier in this news feed.
