As Adirondack (train line MTL-NYC) is not Internet-friendly for RSS feeds I can't profit of my ~11h travelling to check this huge schedule in the way I want to, (= having a timetable view including room, description and speakers). HOPE X has just released a pdf and a xls (wtf??), but these contain only titles and room.
So I've coded an ics generator to process their feed. The result file is available at http://acaia.ca/hopex.ics and should be up to date with the original RSS.
