The only thing done in hardware is generally the LAN switching. All bridging to/from WIFI and all traffic to/from the Internet (WAN port) is via a software path. The technology exists so it could be done in hardware, it just isn't necessary because the software path is fast enough.
I expect your house may be either doing or capable of doing a lot of IPv6 if the devices, software, etc are fairly current.
Apple and Microsoft both use IPv6 for many functions, transparent to what the user sees.
Apple has used IPv6 (linklocal) for configuring their Airport routers, for example. Many of the cloud based services like back to my mac are tunneling IPv6 in IPv4.
Microsoft tunnels IPv6 for their cloud services, also.
It does not seem widely off - I used to manage a team of 10 people who did the admin/networking for 8000 users. We did not do all of the end user hand holding, though some days it seemed like we did. Our ratio was about 1:1 users to computers, so your needs may be higher with the larger percentage of users.
Rules of thumb are useful, but in any support function is it really important to keep data on what you are doing. If the team works really hard it seems like you aren't even there. Most people don't understand the "magic" required to keep this stuff working. If you track calls/time, it is much easier to ask for more resources/staff when they are needed.
Telsa has a valuation in the billions of dollars.
The way they pay back the loan is by having what the VC's call a "positive exit" - the company going public or being acquired by a larger company. Even growing organically they could do it - they are manufacturing constrained right now, the loan is all about expanding manufacturing.
Personally, I would have rather seen the gov't broker a deal for Telsa to use the NUMI manufacturing plant in Fremont rather than get big gov't loan to build a new plant at the same time they are giving Toyota a bunch of incentives to keep NUMI open after GM walked.
If I fit in the roadster, I'd want one. Got a ride in one and it was wicked fun. 0-80 in half a block.
While I'm not going to defend those who don't accept evolution, would it be too much to ask for the NY Times to state the percentages are in actual numbers rather than the impossible to read graph?
The graph sort of indicates that the US evolution acceptance is about 70% which is lower than it should be, but higher than the tone of the article would lead you to think. This is typical of the NY Times in that they are quite certain that those in NY are smarter and more worldly than those in the rest of the country.
It will likely be similar to motorcycle insurance -- fairly cheap because the primary victim of any accident is the now dead operator.
Like small airplanes, these will not inflict major damage to most structures. I'd agree that it is not a great thing to have fall on your head, but the screams of the about to die pilot should be enough warning to get out of the way.
The coupon code to get it for $49 (free shipping) is:
PR49B I didn't notice anything in the EULA that required more payment if you don't use it. This discount is for BLOGs, so/. is even an appropriate use.
I ordered two with that code 2 weeks ago. I've installed one and so far am happy with it. The only installation surprise what that it really wants you to use its antenna instead of any you may have already. The included small 6x8" antenna did get a strong signal easily so it wasn't a big deal for me.
Obviously the service is not the same as renting/ripping/archiving DVD's, but if you just want to pay $2-$4 to watch a movie with no lead time, it works fine. I like that there are no monthly fees. Netflix has a few day delay and my local Blockbuster keeps randomly charging me for not returning movies I didn't rent, so I've been looking for an alternative.
I've been told that Moviebeam wants to have movies out the same time as they get released on DVD, but the selection hasn't been much better than what's available on DirecTv PPV. It has about a hundred movies, most of which are fairly recent at $4 -- some are older and $2.
The quality looked pretty good. It requires HDMI for HDTV and I didn't have a free port so I'm just doing SD right now, but even on a 70" 16:9 TV, it looked pretty good; almost as good as a DVD.
I've spoken to a lot of managers at high-tech companies that won't hire fresh MIT grads because a)they don't know anything actually useful and b)they think they know everything, so when they're doing something wrong, they don't listen to coworkers, team leaders, and managers.
As a manager at a high tech company, my experience has been entirely different. While we don't get a lot of MIT graduates coming to the west coast, the ones who have worked for me have been fantastic in terms of being bright, energetic, as well as good with both working on technical problems and dealing with people. I'd believe that a school like MIT could produce some freaks, but I'd love to get more of the same of what I've experienced in the past.
I think they were mapping the existing PUP into the IP address. Since PUP is two 8 bit numbers it would map cleanly into the third and forth octets of a v4 IP address. When I was at Xerox I also mapped IP and the PUP space, but it was in '87 and we ARP'ed (and PROBEd - thank you hp). We did the mapping to leverage the existing addressing plan. Since he was just doing this for Stanford he may have hardcoded the other two octets.
Xerox also had multiprotocol routers called Dicentras hand crafted at PARC. They were also based on multibus boxes with 2901 bitslice processor "D machines". They routed PUP and XNS. Hardware, software and ideas seems to flow around the valley pretty freely in the 80's, so I don't know which came first. A project was started to implement IP on them, but it was easier to just buy cisco processor boards and stick them in the dicentra chassis full of 3COM ethernet cards; that made them useful until the 68000's ran out of gas.
Cabletron and Synoptics were the two major leading competitors as proprietary Ethernet over twisted pair moved to 10BaseT. As I recall, Synoptics sold more and innovated more, but Cabletron kept them honest, especially on price. SynOptics did the heavy lifting on the 10BaseT spec.
The US vs Europe debate fails to notice that there exists an operational alternative to the US GPS system. Russia has had a working system for years. There are shipping chipsets that do both GPS and GLONASS.

Europe should just slip the Russians a few Euro to keep it running
and get a contractual agreement on levels of service.
