Yeah. RSA sucks.
Ok.

Re: another method to crack RSA
Um, no. These guys didn't crack RSA (which, by the way, does not suck) at all, they cracked OpenSSL, by exploiting the specific way it uses RSA, and to do it they needed physical access to the machine that had the private key they were trying to steal. This is not particularly interesting or exciting at a practical level, since it would be much easier to steal the hard drive with the key on it or beat up the sysadmin than to rewire the power supply of the server's CPU.

netrek 2010 bug report: hints on tac screen
Today installed netrek 2010 on two machines, one vista, one xp. On both, sometimes upon entering the game, a hint would appear on the tactical screen. Not in a hint box spanning the tac and galactic, but entirely on the tac sceen, with no obvious way to remove it. Redraws of screen objects would erase the hint as a word written on sand being erased by waves, so that after flying around enough, all trace of the hint was gone.

Ntrek 2010 bug report: help screen when killed
On XP today, I observed that if a player had the help screen up when they were killed, it remained up on the team select screen, would not go away with h being pressed, and only the quit button could be used, not a team selection button. I didn't try to verify this with repitition.

Yes but RSA has (for some keysizes) already been cracked. Up to 768-bit keysize has been successfully factored: http://www.rsa.com/rsalabs/node.asp?id=2092 And who knows how much long 1024-bit keys are safe: http://arstechnica.com/security/news/2010/01/768-bit-rsa-cracked-1024-bit-safe-for-now.ars Zach

Cannot repeat entirely. Help window cannot be closed at the team outfit screen, this is by design and has always been that way. However, I am able to freely reposition the help window if it is blocking team select windows, and able to use team select buttons as normal.

Everyone knew 768 bits wasn't going to be enough fifteen years ago; there are no surprises here. Not that any of this is particularly relevant right now, since RSA blessing is currently deprecated.
