Welcome
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...
Subscribe to weekly updates about things i have added to the site or thought interesting during the last week.
You could also follow me on twitter or not... does anyone even use twitter anymore?
If you found something useful or like my work, you can buy me a coffee here. Mmm Coffee. ☕
