Links of interest from June 24, 2012 through June 27, 2012:

CodePen: Pen
A nice tool for playing with front-end web code. It even understands Markdown. Not sure I personally have any reason to use this over jsfiddle yet, but it’s really well done.
Peity - progressive canvas charts
Now that’s cool. I have to start gathering statistics so I can make good use of it. Maybe a poll… nope.
A code editor developed in HTML, CSS and JavaScript by Adobe. Very experimental, but pretty cool.
handleOpenURL: Shared Interapp Communication on iOS
Great resource for finding iOS url handlers, via MacDrifter.
Baseline.js – Vertical rhythm made easy
Intriguing. Not sure I want a website layout dependent on JavaScript, but there are definitely times when this would come in handy.
