Many websites use bots to automate tasks and add useful (and sometimes harmful) functionality. For instance, there are reddit bots that can help you stabilize shaky videos, remind you of events or even vote on the usefulness of other bots.
Introduction Over the last year or so, I’ve been playing around with functional programming. As the first few lines of the Wikipedia page suggest, functional programming is all about expressing a computation or algorithm as the composition of functions rather than using a state that changes over time.
As I mentioned in my first article on this blog, I’m now using Hugo, the static site generator to build my personal website. Due to the needs of my work environment (mostly because I need to use MS Word and certain MATLAB features on a regular basis), I’ve been primarily using Windows as my operating system for the past year or so.
When prototyping programs that deal with lots of data on an Arduino and other embedded systems or even on full blown computers, it’s really useful to have a quick tool for plotting the output of the program.
Over the past few months I’ve been spending a lot of time on implementing various signal processing algorithms in C/C++. Things like Kalman Filters, various types of FIR filters and finite state machines.
Xenomai gets tasks to run in real-time by having a co-kernel running alongside the regular linux kernel handling all the time critical tasks. The Xenomai co-kernel is able to do this because of the i-pipe patch that the custom kernel is compiled with.
In my lab, we recently started moving away from Simulink’s Real-Time packages and towards Real-Time Linux for implementing the low level control of our robots. I thought I would document what I went through to get Xenomai (A Real-Time framework for linux) working stably as a resource for others trying to get started on the same thing.
