Topic: Web programming
The diagram below summarizes my recent cursory survey of web browsers. I think the one important conclusion that can be drawn is this: Webkit will be critical in the future. I know at least one person who does not have a computer, but uses Facebook from her mobile phone. There will be more and more people like that. Another important factoid: IE6 is not dead. IE Mobile 6 will use the JavaScript implementation of IE8, but the layout engine is based off of IE6. That will probably induce nausea in most web developers, but it makes me glad I still take care to develop my web apps to run in IE6.
Other notable things:
The repository version of Parenscript will probably break your code.
I have released a new version of uri-template, which fixes a bug in how URI encoding was being performed.
