I want your calendar data!
Do you or your company or your customers have a big calendar of some sort, with hundreds or more events in it? In Outlook or iCal or whatever? Can you export it to iCalendar/ics files?
The please export that file, and run it through my anonymizing script: https://github.com/regebro/plone.app.eventindex/blob/master/anonical.py
Send the result to me. Or just send the ical directly to me, I promise to anonymize it and not keep the original around. I will from this put together massive .ics files that can be used for performance testing on calendars with real data. These ics files will be completely anonymous; only the start, end and recurrence if any, will be kept; and the resulting test sets will be made open source so others can benefit from this test data.
It is for the good of mankind! Especially open source!
