There is no 'British English' 10:13 am

I've no idea if this is right but this is what an English speaker gives: (an honourable mention for anyone who can tell the the one question I had to choose an answer at random for)

Arghh 11:46 am

I've nicely screwed myself. Using the 4th and 5th buttons on my track ball to switch desktop in OS X is really cool. Unfortunately I now find myself using them in Linux to do the same thing. Anyone know of a trivial way I can map them to a keystroke or to make kwin switch desktop on a mouse button press?

Update: I found a solution. Mouse button hot keys )

Hash collisions 08:09 pm
I don't understand this article: "Company claims ability to wipe out file-sharing". If I understand correctly it is some method of serving incorrect blocks to P2P clients in order to make the resultant file broken. To take the example of BitTorrent (which I presume is similar to a number of P2P systems in this regard) the final file is constructed in such a way so that it matches some overall file hash and each block matches a block hash. The system, therefore, must somehow find hash collisions for either MD5, SHA1 or some other hash function. Now it stikes me that even if they have found the holy grail/poisoned challice of a full breakage of MD5 and SHA1 (as opposed to the limited attacks currently possible) that the P2P networks will just use a different hash algorithm. I fail to see how it can work. Of course they haven't released many details so there could be more than meets the eye here.

Update: I found their patent on the method. It appears they just target networks which believe the metadata a client sends along with a file chunk with no overall hashing. Hence it is pretty useless for any modern P2P network. Move along. Nothing to see here.

Tiger update 11:24 pm
I've been looking over the source and I've found a possible cause for the disappearing sticky windows. Would people with Tiger like to test the latest build and see if the problem has improved? I sincerely hope it has otherwise I'm out of ideas :(.
