I am a computer science student who is in their second year at Hull University. I started out teaching myself about various web technologies, and then I managed to get a place at University, where I am now, though I'm currently on an industrial placement. I currently know C# + Monogame / XNA (+ WPF), HTML5, CSS3, Javascript (ES6 + Node.js), PHP and a bit of Python. Oh yeah, and I can use XSLT too.

I love to experiment and learn about new things on a regular basis. You can find some of the things that I've done in the labs and code sections of this website, or on GitHub. My current projects are Pepperminty Wiki, an entire wiki engine in a single file (the source code is spread across multiple files - don't worry!), and a Prolog Visualisation Tool, although the latter is in its very early stages.

I can also be found in a number of other different places around the web. I've compiled a list of the places that I can remember below.

I can be contacted at the email address webmaster at starbeamrainbowlabs dot com. Suggestions, bug reports and constructive criticism are always welcome.

Running Prolog on Linux

The learning prolog banner. Hello! I hope you had a nice restful Easter. I've been a bit busy this last 6 months, but I've got a holiday at the moment, and I've just received a lovely email about my learning prolog series. It's reminded me about how much I actually rather like (swi) prolog (I'm a bit nuts, I know :P), and I've decided that it would be splendid if I could get back into it a bit.

I'm not sure whether it'll go anywhere, but I'm going to look into web crawling and parsing HTML. Anyway, since I'm re-discovering prolog, I had a teensy bit of trouble getting prolog to run one of my old scripts just now, so I thought I'd blog about it to save me the trouble next time :D

Running prolog scripts on linux isn't actually that hard. First, you need to install SWI-Prolog:

sudo add-apt-repository ppa:swi-prolog/stable
sudo apt install swi-prolog-nox

Then, you run a prolog script like this:

swipl -f ./
Welcome to SWI-Prolog (threaded, 64 bits, version 7.4.1)
SWI-Prolog comes with ABSOLUTELY NO WARRANTY. This is free software.
Please run ?- license. for legal details.

For online help and background, visit
For built-in help, use ?- help(Topic). or ?- apropos(Word).


...then you can interact with your Prolog knowledge bases as normal. When you want to exit, the easiest way I've found is if you press CTRL + D.

If, however, you're lazy and don't want to type prolog -f out every time you want to run your script, you can prefix your file with the following shebang:

#!/usr/bin/prolog -f 

Make sure it's the very first line in the file. Prolog appears to ignore it and carry on regardless. Then you can run it like this (making sure you've chmod +x'd it first:
