• Website url whitelists

  - by buggedcom

  I'm building a user content parser and am adding an automatic link parser. I'm adding a dialogue, that confirms that the user wants to go to the particular site being linked to. This is for two reasons. Anti phishing and spam combating. However I want to be able to disable both the dialogue and nofollow additions with commonly used websites, so I'm building a whitelist. Are there any common whitelists about or should I start building one from scratch?

• Mysql: Perform of NOT EXISTS. Is it possible to improve permofance?

  - by petRUShka

  I have two tables posts and comments. Table comments have post_id attribute. I need to get all posts with type "open", for which there are no comments with type "good" and created date MAY 1. Is it optimal to use such SQL-query: SELECT posts.* FROM posts WHERE NOT EXISTS ( SELECT comments.id FROM comments WHERE comments.post_id = posts.id AND comments.comment_type = 'good' AND comments.created_at BETWEEN '2010-05-01 00:00:00' AND '2010-05-01 23:59:59') I'm not sure that NOT EXISTS is perfect construction in this situation.
