Does anyone have a comprehensive list of informative CF blog posts, which may be useful for most people?

For instance I found the following blogs to be very useful:

http://mirror.codeforces.com/blog/entry/15890(Segment Trees)

http://mirror.codeforces.com/blog/entry/16221 (Graph Algos)

http://mirror.codeforces.com/blog/entry/15729 (Tree related DS)

PS: I will add useful links here whenever I find them. Maybe we can have a common tag across all such posts so that they can easily be found?
