Being able to put components to sleep is pretty much worthless if you want to run anything resembling a server. Hardware manufacturers need to focus less on sleep states, and more on making components consume less power while they're active.
A good first step is the 80plus initiative for power supplies. By increasing the power supply from 65-70% to 80-85% efficiency, you gain a decent amount of active power savings right off the top. If you care at all about conservation, make sure to check the efficiency rating of your next power supply.
The people at Intel and AMD have made great strides toward power efficient CPUs, which can scale back their clocks on-demand without noticeably hurting performance, but the real remaining problem areas are in video cards, RAM, and especially hard drives.
The ideal computer would consume almost zero power while sitting there doing "nothing," but be able to wake up at a moment's notice to handle requests from the user or the network. Power management should be hardware-based and completely transparent. ACPI is just a dirty hack that's becoming more useless as network accessibility becomes more important.
That middle-clicking a tab to paste behavior always throws me off when I use Firefox on Linux. I'm used to using middle-click to CLOSE a tab, not paste to it.
You can still use the old rabbit ear antennas with an ATSC DTV decoder box. The digital channels are in the regular UHF band, so there's no need to get a different "omg DIGITAL!!" antenna.
I noticed something similar with this Dell Inspiron E1405 laptop. It's got an Intel ICH7M chipset, and according to the following page, it's supposed to be possible to switch the SATA controller to AHCI mode, rather than legacy mode:
However, there is no option to make this change in the BIOS, like people have reported with similar systems. So in Linux, I'm stuck with the PIIX driver instead of the AHCI driver. I'm not completely sure if there would be any practical benefit to using AHCI mode, but I do know that currently DMA isn't working correctly on the DVD drive, and my options are being artificially limited.

IPv6 Essentials

No, IPv4 can't be a subset of IPv6. Sure, it would have been possible to let an IPv6 address send packets to an IPv4 address, using regular IPv4 packets, but then how would the target host send back a reply?
You can't have a subset; addressing needs to be 1-to-1 unless you throw logic like NAT in the middle.
Probably the simplest way to get an IPv6 address these days is using 6to4.
Every IPv4 address has been assigned a big block of IPv6 addresses, with a prefix of 2002:[IPv4_address]. If you've got a 6to4 address, and want to send a packet to another 6to4 address, it just gets encapsulated and sent directly to the destination over the IPv4 Internet.
However, if you want to send a packet from a 6to4 address to a "real" IPv6 address with a 2001: prefix, then it needs to get routed through a 6to4 gateway.
If your ISP has a clue, then you should be able to traceroute to the 192.88.99.1 anycast address, and reach a gateway that's somewhat close to you. For a fun time, try it from different computers on different ISPs to see where you end up.
The nice thing about 6to4 is, if you can get your router set up with a 6to4 address, then it can advertise that prefix on your LAN, and all your LAN computers can have a public IPv6 address.
At some level, it's like the ultimate stateless NAT traversal system: you can send packets directly from one LAN to another without needing to do any of that port forwarding nonsense. It really shows you how the Internet was designed to work in the first place.
Wow, I'd never looked at debial-legal before, so I went there and the first thing I saw was people arguing over whether the GPL itself violates the Debian Free Software Guidelines...
The fact that a TV picture looks "pretty good" is testament to the fact that our vision isn't really 3D. Human vision is basically 2D plus a little bit of extra depth information. If you could actually experience real 3D vision, it would be nothing short of completely f*cking mindblowing.
Well, really the problem is that human vision is only 2.5D to begin with. In order to have true 3D vision, you would need to have 4D eyes with a 3D retina surface. That would allow you to look at a solid object, and see every point inside it, without any points being "in front of" any others. Trying to see 3D from within a 3D universe is analogical to trying to look at a photograph from the edge; you're trying to remap a 2D space onto a straight line.
You could probably send true 3D through a direct neural link, but that's obviously not practical yet.

All they have to do is find somebody to sue. Isn't that how things work these days?

The insta-crash only seems to work on Linux though.

No, that's under 2 gigabits/sec.

As far as TV goes, remember that satellite is an alternative to cable.

Your comment is starting to make perfect sense.
When you see "No this isn't a Typo" on the front page of slashdot, be very skeptical.
