the way i read it was that just about any os is/can be affected by it :surp: cause of shared cache infection or somehting like that, in that a ht kernel essentially uses a smp kernel, therefore its assumed that when ur running smp that the caches, etc are separate...but on a ht cpu, the cache is shared, and thats where the flaw comes into play :-?

# Do I need to worry about my home computer?

Probably not. This security flaw is primarily a problem for servers.
IF this is serious problem then why the guy said home computer users shouldn't worry about it?

Administrators of multi-user systems are strongly advised to take action to disable Hyper-Threading immediately; single-user systems (i.e., desktop computers) are not affected.

most home computers are run in single user mode. the ht flaw only allows a thread to read data from another thread, so unless you've got multiple users running apps simultaneously it's not a problem. now, if you have "fast user switching" turned on in xp, you can actually get apps running under one account to sniff data from programs running under another account.

anyhoo, if you have you puter at school, don't set up accounts for your buddies on it, and if ya do, be sure fast user switching is off that way you are forced to logoff. ;)

I don't think you need X Windows to run on a server. Use a console! :P This way, it'll save more resources for other services which need it. ;)
