There's certainly quite a bit of booze at an Argentinian hackathon. These were the guys who showed up. Half my team disappeared after the Friday evening.
I routinely read through the comments before I actually click on the link to the article. It's a quick indicator to the quality of the article and often, I learn more from the comments vs. the article itself.
I used to do the same thing until I realized how much it affected my interpretation of the article. It colored my thoughts, making me part of the hivemind. Now I read the article first, then wait a few seconds before looking at what other people think so I can better for my own opinion.
Somewhere between 50-75% of the time I don't read the articles posted to HN. The comments are frequenty more interesting, and almost always have commenters that are more informed about the original topic.
Just get her to restore from her most recent backup. She does have a backup, doesn't she? If she didn't bother to backup, she doesn't have much right to be upset.
That it's bad form to be gleeful over others misery. Some people don't care about losing a bunch of files, for others it is a disaster. Yes, she should have had back-ups. But that's no reason to be smug.
Looking forward to your call for help about something.
