HFSC - linux traffic shaping's best kept secret
#!/bin/bash
# As the "bufferbloat" folks have recently re-discovered and/or more widely
# publicized, congestion avoidance algorithms (such as those found in TCP) do
# a great job of allowing network endpoints to negotiate transfer rates that
# maximize a link's bandwidth usage without unduly penalizing any particular
# stream. This allows bulk transfer streams to use the maximum available
# bandwidth without affecting the latency of non-bulk (e.g. interactive)
# streams.

An example on how to use libuv with libcurl's multi interface Should be equally fast on Unixes (uses epoll/kqueue/etc like libev/libevent) but MUCH faster on Windows due to libuv's usage of IO completion ports. Could come in handy if you have to manage several hundreds or thousands of connections!

Advanced Python BLE example with python-glib and Bluez5
import dbus
import time
"""
This gist will do the following things :
1. Setup GLib and a MainLoop. MainLoop is required to receive signals from the dbus
2. Define a simple callback function that will be associated to the signal "Properties Changed" for a specific object (Characteristic).
The callback function will be called when the characteristic value is updated or it's property changed.
