Locust
Scalable open source load testing tool
...The idea behind Locust is to swarm your web site or other systems with attacks from simulated users during a test, with each user behavior defined by you using Python code. This swarming process is then monitored from a web UI in real-time, and will help identify any bottlenecks in your code before real users can come in. As it is completely event-based, Locust can have thousands or even millions of simultaneous users distributed over multiple machines swarming your system. Unlike other event-based apps, it doesn’t use callbacks but uses lightweight processes instead, so you can write very expressive scenarios in Python without complicating it with callbacks. -

Linux Surface
Linux Kernel for Surface Devices
Linux running on Microsoft Surface devices. These days, Linux supports a lot of devices out-of-the-box. As a matter of fact, this includes a good portion of the Microsoft Surface devices—for most parts at least. Unfortunately, Surface devices tend to be a bit special. This is mostly because some hardware choices Microsoft made are rarely (if at all) used by other, more "standard", devices. We aim to send all the changes we make here upstream, but this may take time. This kernel allows us to... -
