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.)

Markdeep

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="http://salomonsson.se/md/markdeep.min.js"></script><script src="http://salomonsson.se/md/markdeep.min.js"></script><script>window.alreadyProcessedMarkdeep||(document.body.style.visibility="visible")</script>

You might want to paste the following at the very top

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>();
vec1.push(1);
vec1.push(2);
vec1.push(3);

// 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];
