It would be nice to see more information on people's profiles than just the problems they solved. Name of problem, ranking, link to problem would be nice to have...

Hi!
Actually, it was planned to do so. You can have a look at our first try at:

http://acm.uva.es/archive/nuevoportal/u ... ?user=1664

That's my profile in the live archive, not very good by the way :-). It shows the number of submissions for each problem, and the best veredict among them. Unfortunatelly, that kind of statistics only work for small log tables (like the one in the live archive, with 100k submissions). If we try to use it in the judge (with over 4.5M submissions), it takes several seconds to run, and it might stall the judge. And about showing the rank for every problem...it takes a lot of CPU time if it's not done properly (you have to change a lot of user's rank everytime someone gets the problem AC), and it means a change on how things are done in the judge now (I mean, in the patch that tries to store data in the new system using the old system, that is the one who actually works). I know they could be done a better way, but as I've never studied databases I've done the best I can.

Anyway, we'll have to wait for the new system to show bettter statistics :) I think it was originally planned to do so. If it wasn't, updating the new system is much easier than updating the old one (or both :P ).

The other thing i would really like is to be able to change my information. I know it has been deactivited for a while, but it would be really useful!
Thank you very much for your dedicated work!

yes, that's true...I should spend some time to allow people to change their profile...
