In one of my previous posts, I mentioned that I was using rainmeter to display useful information such as events in my google calendar on my desktop.
Google updated their calendar to API v3 sometime early this year and this broke the functionality. After waiting few months for a fix, and another few attempting to fix it here, I decided to write a simple version from scratch. I wrote a bash script to curl the ical file and performed a little sed/awk goodness. I then configured rainmeter to display the contents of the text file. For good measure, I setup cron to run the script every 30 minutes to update the calendar.
It may not look as pretty but at least it finally works.

The script can be found on github.
