I would like to start the thread where we can share and get an awareness of some useful tech tools such as sites and softwares.
Here is what I think, that might be of some interst to few people.
1. To automatically refresh any website after desired interval (secs/mins)

2. To get the link of youtube to start a video from the chosen time and not just from the beginning.
http://youtubetime.com/
3. To download the videos from youtube and other websites. There are many such applications but I find "Real Player" the best application for the purpose.
