*''Signatures in Gmail:'' Gmail allows us to consolidate multiple email addresses in a single account. However, it doesn't allow us to mention for which email addresses do we want append the signature. As an example, I would like to append signature containing my webpage address to my office email but not to my personal emails. Currently, if I opt to have signature, Gmail will append it to all of emails regardless of whether the email if sent using office's email address or personal. '''This is has been implemented by Jerome Dane. Here is the [[page|http://userscripts.org/scripts/show/20887]]. Way to go, Jerome!'''
*''Energy harvesting in the gymnasiums:'' In the gyms, there are many exercise machines, such as elliptical, bicycles, etc., which can be used to generate energy in the same manner as the turbines to generate energy. Such a way of generating energy will reduce the carbon footprint of the gyms.
*''A digital calendar-frame:'' We already have frames for digital photos. In the same fashion, we can have a digital calendar-frame that I can hang on the wall or put on my desk. The digital calendar-frame can download my calendar from my computer (e.g. iCal) or from the Internet (e.g. Google Calendar). The digital calendar-frame will always keep itself synchronized. An additional feature would be to create notifications or create an agenda for the day. Although the calendar on my computer or the online version is accessible to other people at home, it is cumbersome to need a computer or a phone to access it. So a digital calendar-frame would be a nice gadget.

I maintain a blog called [[worthsharing|http://worthsharingwitheveryone.blogspot.com/]], where I post the articles,news,software, or anything that I feel is worth sharing with others.
