The key quote here, IMO, is: "Multiple core systems are a boon for anyone who runs multiple processes simultaneously and/or have a lot of services, background processes and other apps running at once."
All the anti-virus, anti-spyware, anti-exploit, DRM, IM clients, mail clients, multimedia "helper" apps, browser "helper" apps, little system tray goodies, etc., etc., and so on, it can start to add up. A lot of home and small business users are running a lot more background and simultaneous stuff than they may realize.
That's not to say these noticeably slow down a 3.2GHz single-core machine with a gig of RAM, but the amount of stuff running in the backgrownd is growing exponentially. Dual core may not be of much benefit to business users now, but how long will that last?

It's a trick question. "IPR" isn't natural, it's an invention (and a relatively recent one at that). So asking where its "natural boundaries" are is silly. Where is are the "natural boundaries" of Rap? Or of lavender? Where is the natural boundary between Spanish and Italian?

It's a silly question.
For the vast bulk of history (and for all time before that), there was no such thing as "Intellectual Property." There isn't even any analogy in the animal kingdom (just imagine Monarch butterflies issuing a take down notice to other butterflies that have infringed on their trademark look and feel). The "natural" state is for people to thinks, say, and do whatever they want, and to copy good ideas wherever they see them. That, in a nutshell, is how culture works. But very recently there has arisen the observation that some good ideas are hard to copy unless the inventor is willing to explain the trick to you. And one way to induce them to do so is to ameliorate their fear that by so doing they will create a host of competitors, by promising to prevent other people from using the trick for awhile provided that they share it.
Sounds like a fair deal, but, like many things, a little greed is all it takes to spoil it for everyone.

And the guys at MS Office are now free to work on something that doesn't already exist.

Snort. Use snort. You have no idea what's happening on your network until you use snort. If you have desktop users, load up the bleeding-snort rulesets and be prepared to panic in horror as you see all the crapware flowing over your network.
Perl. With bash-fu. Like this: $ perl -i.BAK -pe 's/(http://192/ [192]\.168\.0)\.2/$1.3/' `find . -iname "*.htm"` You'll never look at sed again ;)

I work for a very large MSSP, and this makes me quite sad.
Sad, because Snort's source code is not exactly a mystery. And Check Point's technology already does a much better job at preventing intrusions, since it is a firewall and Snort is a really shitty IPS. (All IPS are shitty, sorry. I like Snort for IDS, really) My sadness here is deep and mournful.
I'm also really disappointed, because I hate Sourcefire. I was really looking forward to Check Point reigning in their way-out-of-line sales guys. More than that, tech support at Sourcefire (all 3 guys!) sucks, 'cause they're all arrogant pricks who don't really give a shit about the customer, and honestly believe their code is perfect and never has problems. Actually, that sums up SF pretty well. Check Point, for all their problems, actually listens when we complain, which is nice, though getting things fixed is an ungodly slow process.

Re:irrational fear?
(Score:5, Insightful) Maybe you're missing the possibility that whoever's using Snort in the DoD doesn't want to have to hire a full-time programmer to act as tech support when they can just get a contract with Sourcefire instead? As far as I can tell, this isn't about code, it's about support. Sensitive information occasionally needs to be given to tech support in order to diagnose/fix problems, and the DoD would prefer whoever's on the recieving end to be an American. I wonder if Sourcefire have any support personnel with gov't security clearances.

(Score:5, Interesting)It is possible to build comptuers that are optimized for certain kinds of calculations.[ Reply to This | Parent ]
For example, Gerald Sussman of MIT (a computer scientist) and a Jack Wisdom (a physicist) decided they wanted to do long-term modelling of the solar system's evolution over time. Long time modelling of a multi-body system requires a fantastic amount of calculation. What is the best way to do it?
Sussman and Wisdom came up with a crafty idea: build a computer that is specially configured at the hardware level to do the modelling. Sussman and his colleagues decided that with off-the-shelf parts they could build a computer that would be just as or more capable of modeling this system than a supercomputer would be. The result was the Digital Orrery, a relativlely cheap computer that gave great results. (It is now featured in the Smithsonian museum.)
Think of it: if your computer is going to be doing the Fast Fourier Transform 6.02x10^23 times per day, why not build a superfast chip that does nothing but the FFT rather than express it as software? It's a pretty cool idea. I think this is the sort of thing that Cray computers claims to want to do with its motto.- 1 reply beneath your current threshold.
