This is my test area for webdev. I keep a collection of code here, mostly for my reference. Also if i find a good link, i usually add it here and then forget about it. more...

You could also follow me on twitter. I have a couple of youtube channels if you want to see some video related content. RuneScape 3, Minecraft and also a coding channel here Web Dev.

If you found something useful or like my work, you can buy me a coffee here. Mmm Coffee. ☕

When i was a little kid, I was really scared of the dark. But then I came to understand, dark just means the absence of photons in the visible wavelength -- 400 to 700 nanometers. Then i thought, well, its really silly to be afraid of a lack of photons. Then i wasn't afraid of the dark anymore after that.
