Ask HN: Aggregated Calendar of Industry Events?

Is there a place that compiles events in iCal format for this industry, so I can follow and scan the dates just by looking at my calendar app? I know it'd be impossible to make it a one-size-fits-all solution, since it doesn't take into account location or the caliber of events (from yearly developer's conference that you travel to, to simple meetups nearby), but anything pointing in that direction would be nice.
