Every month I stumble over lot of different videos and articles about web development, here is some of the stuff I came across today.
Jonathan Snook wrote a good article about performance in CSS, it explains some stuff on a very basic level that few people think about when writing their CSS code, even thou the main question in the article is about why there isn't a parent selector. Anyway enough rambling about it, take a look at it "Why we don't have a parent selector" it is well worth taking some time to read.
Also @nathansmith shared some nice videos which are well worth seeing, on of them about HTML5 by Jeremy Keith, not how to use the language more the story behind the language and why it's being design the way it is.
The second video is a presentation of how a web application's development flow can be and some good pointers, like "don't design the entire web app in one go, focus on a frame to expand later on!", the most critical thing is to get something out of the door, so split up all the processes. Anyway I found both of them very informative and would recommend them to anyone with an interest in web development.
