Prolog – Doing othello by Prolog way – D7012E Lab 4

The beginning of the course we had was Haskell, now the next step after that was prolog. So a simple first lab was to find all possible combinations to travel over a sea (between two islands) and move a goose, a fox and a bag of grain over without the fox eating the goose and the goose eating the grain.


Javascript Array Extension – Key value pair

I went totally frustrated earlier when I tried to find a way to match key values to value in arrays (hashmap kind). But I couldn’t find any function for that in javascript. So I decided to write my own extension for the array in javascript. Here is the result. Mind you, it’s only in alpha release. Basic usage:


Installing TinyOS environment on Ubuntu [For Mulle]

This guide will go through how to properly install TinyOs on Ubuntu (most versions included). The installation requires some basic libraries before installing the compiler and other components. I only cover the flashing process for Mulle and no other platforms (some may work if you are lucky, I however have not tried and give no guarantee that it would work).

Remote unraring through nautilus and SSH

I’ve just set up a new NAS/Web/whatever server for my apartment and feel it unnecessary to run unrar on my regular desktop (which leads to a lot of delay as the stream goes NAS -> Workstation -> NAS). So I wrote a quick python script that will work to send an unrar command through a ssh connection to the NAS server which then executes the command on the server which leads to a much quicker unraring of the files. This script however requires that the mounted volumes are located in the same base directory on both computers (for example, I got my archive mounted on /mnt/archive on my NAS, I then have to mount the samba volume on my workstation to /mnt/archive). It contains a quick installation script and all python scripts requires python 3+ (as I have abandoned python < 3 for easier programming).

Automatic iPod python converting script

I don’t really like having to install handbrake or some other program that I have to use every time I want to convert a file to my iPod or android phone. So I decided to run a small python script on my NAS server instead which periodically checks for unconverted files in a specified directory and converts them to the correct format. I will not supply any huge readme files for this release, the code is mostly self-explanatory.


How to re-lock a BitLocker encrypted drive

There's no re-lock alternative directly in the context menu for re-locking an unlocked BitLocker volume. So after a bit of searching I came up with a solution based upon two-three different posts.


TinyDude, Mulle flashing tool

As I have done quite a lot of programming in TinyOs using the Mulle platform and the sm16cf programmer I developed a quick helper for flashing it as using the standard command line for the flash command grew tiresome. The installation of the python script i quite simple, the things you need is:


Hide Spotify from taskbar (Minimize to tray only)
