It's great to give helpful feedback about bugs, but please edit out swipes like "Major fail" when doing so. They're especially noxious when someone's presenting their own work. We want people do to that freely on HN, and get helpful feedback, not internet nastiness.
Whoa, sorry I think you added more emotional personal attack meaning to major fail than I intended. I major fail all the time, it's part of life and getting better.
Please don't respond to a bad comment with an even worse one. That just makes things even worse, and is exactly what the site guidelines ask you not to do: https://news.ycombinator.com/newsguidelines.html
