Simpi
As of October 18, Simpi is running Athena 10, as opposed to Debathena (starting summer '08) and Athena 9 (before summer '08). Athena 10 is in beta (official release around IAP '09; deployment to clusters around summer '09), and while it is a significant improvement over Athena 9 there are lots of usability issues that need to be ironed out. People should report these issues here.
I (Meeg) will be checking this page roughly daily. If I can find a workaround, it will be added to the hall computer how-to. If the issue is specific to our hardware or setup, I'll fix it as best I can. If the issue is a general problem with Athena 10, I will report it to the testers list. In any case I'll make a note on this page.
Depending on how this goes, I may switch Simpi back to Debathena, in which case this page will still be used for help requests with Simpi.
