By rough count I went through 160 Tweets to cull out the interesting links for today’s post. It makes me wonder if I tweet too much. Of course for me Twitter is a lot about the conversation which explains a lot of that number. I hope for conversations here in the comments of this blog as well. So I hope if you read something here or in another post that you disagree with, find interesting, or disturbing, or which needs amplification or clarification you will leave a comment or two.

While I’m taking care of house keeping, the URL of this blog has changed to http://blogs.msdn.com/b/AlfredTh The new piece is the /b in the middle. There are redirects in place so people will hopefully get to the right place using old links. But if you have a link to this blog (and I really appreciate those of you who do) if you get a few minutes could you update the link there? It makes life easier for the search engines. Thanks!

Explaining why we reinvent software is a blog post by Mark Guzdial that is the single best job of explaining why we have students write code to solve problems that have been solved and for which libraries exist. IF a student has ever asked “why are you making us write sorts when there are functions to do that already?” this post will help you prepare your answer. Don’t miss it.
