Simple Algebra

I always forget or mix up how to extract variables from a formula when division is involved, which always slows me down as I have to sit with pen and paper to get it straight. So lets just get it straight and simple here, so I can look it up whenever I need it!

(Note: the one furthest down is the interesting one. Not even sure why I have addition in there, but I let it stay.)

Creative Parental Leave!

Today is the last day of my parental leave. For 6 months I’ve been home with my twin daughters (they were almost 9 months old when I started, and soon 16 months).

I’ve spent a lot of time with them, but I have managed to stay creative in the few hours every now and then when they were taking naps. I have to say I’m a bit impressed in retrospect!

A few days ago I came across Markdeep. A simple way to write formatted documents using markdown syntax.

I think markdown syntax is nice, and I’m already using it for all content on this site.

The idea is that you only need a small snippet of javascript text in the bottom of the document. You edit it in your regular notepad app, and view it through a browser. It will fall back to unformatted markdown text (still pretty readable) if it cannot fetch the javascript file.

However the original markdeep.js has a big flaw. At least for me!
It cannot detect single line breaks!
Like this one.
So I modified it a bit.

If you want to use it, just copy and paste the following snippet in the bottom of a text document, and make sure the file ending is .html.

<!-- Markdeep: --><style class="fallback">body{visibility:hidden;white-space:pre;font-family:monospace}</style><script src=""></script><script src=""></script><script>window.alreadyProcessedMarkdeep||("visible")</script>

You might want to paste the following at the very top
<meta charset="utf-8">

Good bye Wordpress, hello static html!

Finally! After more than two months of work I can publish my new website, where blog, portfolio and devlogs are merged, using Hugo to generate static content.

This is the first time I’ve done html in over ten years… I cannot say I miss it. But at least this meant that I could throw TWO wordpress sites in the dumpster, so I guess it was worth it.

Now on to code some fun stuff again!

Some great press coverage on Ripple Dot Zero

On June 28, 2013, me and Simon finally released our long running hobby project Ripple Dot Zero, and soon after it began to spread across the internet. We were of course hoping to get some attention for the game, but we were completely overwhelmed by the response we recieved from press and fans.

Here are a selected number of reviews and comments. And I have to say: getting responses like this really warms my heart!

Destructoid: Free PC game Ripple Dot Zero is Sonic mixed with Strider

US GAMER: Ripple Dot Zero Totally Just Made My Day

Indie statik: Trip Back to Gushers and Bubsy: Ripple Dot Zero 16-bit action platforming nostalgia nailed – Ripple Dot Zero

This forum thread was created on Neogaf:

Ripple was also featured on Nitromes weekly “pixel love”, and after a while a fan-made wiki appeared:

A huge thanks to everyone who has showed your support to us in articles, social media, video playthroughs and email. It means the world to us.

Ripple Dot Zero gets release date!

(Edit: Ripple Dot Zero is live and playable on

If you missed the announcement-trailer you have to check it out immediately! Yes now! Do it!

In-game screenshot from Ripple Dot Zero

Today is a big day for me. Today we announce the official release date for Ripple Dot Zero, my long ever-lasting game project together with Simon (you can find more Ripple info on our Pixeltruss-blog), but right now I just want to share my personal view.

I wrote the very first line of code for this project in February 2008, that was for our custom made level editor, and started working on the game engine shortly thereafter. That is more than five years ago!!!

Actionscript Vector Short Hand Notation

I can never remember the short hand notation for Vectors in actionscript 3, so I write it down here once and for all. Hopefully it might even help someone else.

You can declare and instanciate a new Vector by typing one of the following:

// Long way
var vec1:Vector.<int> = new Vector.<int>();

// A little bit better
var vec2:Vector.<int> = Vector.<int>([1, 2, 3]);

// Yeah, I like this one B-)
var vec3:Vector.<int> = new <int>[1,2,3];

Ludum Dare 20: My first go with XNA

Theme: “It’s dangerous to go alone! Take this!”

This was the first time I participate in Ludum Dare, and I had decided to use XNA, a framework I had never used before (but Ludum Dare is a fine motivator to learn something new).

The bad news is that I failed. Pretty bad! This is what happened…

Silver medal at Android Hackathon

I participated in Android Hackathon this weekend, where the goal was to build a game for an Android phone in one day – and the theme was retro (8-16 bits).
