In this post I will talk about the use of unsigned (integral) types in C++, or perhaps more specifically the rationale for using them. In my experience, it is common to use unsigned types for any variable holding a value that cannot be negative. Say, the number of bytes in a buffer. On the face of . . .

This post is a result of looking into a slow-start performance issue in uTP. Slow-start is a mechanism in TCP employed to discover the capacity of a link, before transitioning into the steady state regime of additive increase and multiplicative ... [More] decrease.

The main mechanism libtorrent uses to report events and errors to the client is via alerts. Alerts are messages as c++ objects with additional information depending on the type of message. Periodically clients poll for new alerts from a session object. In the next major release of libtorrent detailed peer logging will be available as . . .

I have recently revisited the bdecoder in libtorrent, and ended up implementing a new bdecoder that is two orders of magnitude faster than the original (naive) parser. This is the 3rd decoder in libtorrent’s history, and I would like to cover its evolution of parsing bencoded data. First off, the main reason for me to write a . . .
