Small Akka-http + Dart application. Sources available at GitHub.
WIP, right now it is just a Dart based piano that can record and play back.

More stuff at my GitHub account.


Mostly about programming and technology. Whenever I have some cool piece of code I want to show other people, I talk about it here.
Sufficient and Necessary Conditions
My blog at SciLogs. About how science affects our lives and vice-versa. Kind of hibernating right now.

Elsewhere on the net

Mostly news retweets and bad jokes.
A few small projects and experiments, mostly.
I love my badges! Trying to reach 90th percentile on Algorithms and FP right now.
Some more professional information.
Google Plus
Usually not very active, but some interesting news sometimes that I only see there. Also a good place to post large content unfit for twitter.
