Everyone has their list of technical sites / blogs they enjoy visiting from time to time. I think it's imperative to get yourself (and sometimes force yourself) to read something technical, even if it's something you think you already know. It's always a chance to fill any gaps or simply refresh your knowledge.
I've found some sites that are great, especially when it comes to the refreshing what you know. There are a lot more blogs I regularly visit but I like these 3 when I just want to quickly learn/review something.
Please feel free to share any of your favourites.
