But does a vendor HAVE to make a dual core chip with two of the same processor? Perhaps gains could be made using a less powerful, commodity chip core and pairing it to a top of the line core.
But the less powerful core does not exist, so they'd have to design it. And the design cost is killer.
However, assuming unlimited design budget and schedule, there are some academic papers showing that heterogeneous cores are a good idea.
Most of the other responses are wrong; the manufacturing process and core revision have nothing to do with it. The single-core chips are faster (2.8GHz) than the dual-core chips (2.4GHz); since higher frequencies use much higher power, the power ends up being the same between the two chips.
And in the mean time, it gives us ample time to start to build a QAM256 stream capture device......which has nothing to do with the broadcast flag. (QAM256 is used in digital cable, which is not broadcast.)
BTW, the EyeTV 500 (and I'm sure other products) can record QAM.
No, read it again. If you want more than a T1 (i.e. a T3), then you'll pay $6K/month. I don't think that's very reasonable though, since if you only wanted 6Mbps I suspect you'd be better off bonding a few T1s instead of buying a T3.
The first is that this can probably be exploited by malware/spyware to make "invisible" interfaces that sit over top of existing applications, happily monitoring everything you're doing.
Transparent windows don't "see" the windows underneath them. Either you can capture the screen (which you can do in current Windows without having to display anything (cf. VNC)) or you can't.
But by far the worst is going to be the end-user customization. Want transparent yellow spinning windows that change opacity based on the phase of the moon? Bet you can do that!
I don't think that's possible, since a Spotlight plugin takes one file as input and produces one set of metadata as output. In order for each message to appear as a separate object to Spotlight, each message would have to be a separate file. Or Apple will have to fix Spotlight.
For ACLs to work at all, they must be enabled for a particular volume. The Workgroup Manager application in Mac OS X 10.4 Server can do this, but that application is not included with the normal (non-server) version of Tiger. There is a command-line work-around, however. This command will enable ACLs on the boot volume.
The problem is that Entourage would have to be rearchitected to store each message in a separate file in order for it to support Spotlight. I don't see that happening.
And, of course, if the OS can't access the TPM chip because it is unsigned, like Linux...
Take off the tinfoil hat; Linux already supports the TPM and prototypes of this secure boot feature have been available for Linux for a while IIRC.
The point of this is to render Windows partitions unreadable from [other operating systems] and call it a 'feature'.
Yes, that is exactly the point, and it is not a secret. Only turn it on if that's what you want.
Meanwhile, people who steal laptops will just boot them up, and use them to get the data off, like they always have, because people use stupid passwords or none at all.
Probably, but you can't help people who can't be helped. Secure boot will benefit people who take care to use good passwords, have backups, don't dual-boot, and are worried about having their computer stolen.
People will generally only move to an incompatible platform/protocol/file format if it is about 2X better than the old one. I've read that JPEG 2000 is only about 30% more efficient than JPEG.

To pass the TCK they can't drop anything.
The companies own the code and they contribute it to OSS projects instead of the individual coders. The result is the same.

It's even worse than it appears: WiMax doesn't work in traffic. (Have you seen the size of the CPE?)

So what? Let the users annoy themselves.
Sun came up with (at first glance) a similar thing called Service Management Facility in Solaris 10.
That's why smart people use low-end PCs as thin clients.
Too bad a Sun Ray costs more than a diskless PC.
This is answered in the presentation; 30 users consume less than 100Mbps.
I wonder if their FPGA-based design is really cheaper than using a Geode or Xilleon.

doesn't file system level encryption already solve this problem?
Where do you store the key? MS proposes to effectively store it in the motherboard, so that the user doesn't have to remember it or carry a token.

You have to hash the bootloader. But you can boot Linux using the Windows bootloader; it isn't very popular but it works.

The data is encrypted; that's the whole point.
You're ignoring the fact that few people watch over-the-air TV. If you have cable or satellite, you don't need to buy a converter box.
TV stations are already broadcasting analog and digital in parallel. Likewise, digital tuners are already mandated on TVs above a certain size.
People will generally only move to an incompatible platform/protocol/file format if it is about 2X better than the old one. I've read that JPEG 2000 is only about 30% more efficient than JPEG.
And then someone will whip out a patent which they claim applies to JPEG 2000.
It's getting to the point where you can only trust stuff that's over 21 years old.
