twitter2gTalk Goes Live!

Get your tweets onto Google Talk!

Twitter: A free social networking and micro-blogging service that allows users to send "updates" (or "tweets"; text-based posts, up to 140 characters long) to the Twitter website, via short message service (SMS), instant messaging, or a third-party application such as Twitterrific or Facebook.

gTalk: (Google Talk) is a Windows and web-based application for voice over internet (VOIP) and instant messaging, offered by Google.

twitter2gTalk: Takes your current tweet and sets it as your Google Talk status (away) message.

I've been toying with this for a while now. I really wanted to launch twitter2gTalk as a service that anyone could use. I had the backend code all done and was dragging my feet writing the django front-end. I went to a hackathon for Google AppEngine and converted most of the code to run on that. You need a Google Account to login, but then again, you need one to use gTalk anyway.

I hope some people will find this cool or useful (some people have been waiting for this and already signed up). Feel free to follow me or the app on twitter for feature updates or subscribe to this blog.

Update Google Talk status with Twitter

I've had this idea in my head for a while and just got it to work this morning.

Basically you send a tweet from Twitter and this script runs, picks up your current twitter status, and if need be, updates your gChat status. I'm working on a service version of this where you could use gpowered.net to do all this for you. Stay tuned =) If I change the version of the script that I have running in the service, you will be able to see the source code that I have checked in here

For those of you that don't know what Twitter is:
"Twitter is a free social networking and micro-blogging service that allows users to send "updates" (or "tweets"; text-based posts, up to 140 characters long) to the Twitter website, via short message service (e.g. on a cell phone), instant messaging, or a third-party application such as Twitterrific or Facebook. Updates are displayed on the user's profile page and instantly delivered to other users who have signed up to receive them. The sender can restrict delivery to those in his or her circle of friends (delivery to everyone is the default). Users can receive updates via the Twitter website, instant messaging, SMS, RSS, email or through an application. For SMS, four gateway numbers are currently available: short codes for the USA, Canada, and India, as well as a UK number for international use. Several third parties offer posting and receiving updates via email." (Wikipidia)
