I moved solutions for problems that were previously hosted on this blog to https://github.com/binaryspaceship/competetive-programming-solutions. Check them out there.
As I am now a happy owner of domain thebigheadache.com, I plan to concentrate more on writing about distributed systems (microservices, monitoring, etc.) and machine learning in cloud (Spark, Hive, etc.). Related content, like C++ REST benchmark, will be moved to the new platform, and all other will be archived on Github.
Stay tuned, interesting times are coming!
