Create your own weather station on Twitter.
With a few simple steps and the following code, you can have weather information for where you live automatically updated to your twitter account. The following steps and python program are for a Unix/Linux/Mac environment. I am sure they can easily be adapted to Windows.
Save the following program on you computer under the name of your choice. You can also choose to download this program from here. Don't forget to set the execute mode for this file with:
chmod a+x /usr/local/bin/twitter_weather.py
Update the variable
PASSWORD with the username
and password of your twitter account.
Update the variable
URL with the
XML file for your city. A list of
supported cities can be found at
careful to use the
XML and not the
crontab entry in you system to update the weather every
few hours. A reasonable value will be every 6 hours.
1 */6 * * * /usr/local/bin/twitter_weather.py
Now you have weather information updated 4 times a day.
The source code

If you are using this program you can post a comment here or send me an email and I will follow your weather station from the ones I am already running on twitter.
Twitter Weather Bot
Here is the Sockeris machine based on a 100 Mhz 486 class processor. That I use to run all the twitter weather stations I manage. It's run OpenBSD embedded in a 64Mb flash card and Python 2.7 and easily manage a dozen of twitter accounts.
