Yahoo! publishes DomainKeys proposal
Yahoo! has published its proposals to prevent e-mail spoofing and submitted them to the Internet Engineering Task Force (IETF). It looks like it's a souped up reverse-DNS lookup with e-mails signed with a key.

The problem with Linux
The current edition of Fortune has the best summary I've read of how Linux users are open to lawsuits from SCO. You should read Gunning for Linux if you have a Fortune sub. If not I have a copy. There are lots of twists, but this passage best summarises what the issue is:
"(Steve) Mills (head of IBM's software group) stated that while Linux lagged behind Unix at the moment (January 2003), IBM would exploit its expertise with AIX to bring it up to speed."
"In this and earlier public statements, IBM implied that it was grafting sophiticated code from AIX onto Linux to accelerate Linux's commercial upgrade. (Darl) McBride (former Novell executive and CEO of SCO) believed that IBM couldn't do that, since all AIX code constituted, in his view a UNIX derivative whose sourcecode IBM had to keep secret under its licences."

The Secret Life of Copiers
From CFO.com...
Most copy machines are now full-blown IT devices, with network and E-mail server connectivity. Any information stored on them can often be accessed by employees and targeted by hackers or thieves.
If only!

I don't think that any of the copiers that the Economist has (at least in Regent Street) are likely to be considered security risks. "Full-blown IT devices" ?? with network and email functionality ??
The copier on the 2nd floor here can't even manage photocopying functionality half of the time !!
An interesting cfo article thoug.

Two processors good, four processors better?
In trying to find out why Performance Manager shows our IBM x345 series servers as having four processors when in fact they have two (they're dual Xeon 2.0GHz). I came across this great "Introduction to Multithreading, Superthreading and Hyperthreading" on Arstechnica. I don't think that this has any relation to the real Arse here or here (caution: sometimes R rated). Anyway, the Intel Xeon processor supports Intel Hyperthreading Technology, which (they say) makes a single physical processor appear as two logical processors. Seems that we'll need to upgrade the OS from W2K to take full advantage, though.

I started using my Gmail account today. I'll let you know how I get on with it's search and other tools...If they want to read my mail, they can. Until someone else offers me 1Gb storage, it seems like a pretty good deal.
