When I was training for my CCNA, they were telling us that most people use static port-based VLAN membership these days for corporate networks because it reduces overhead. I, on the other hand, was a big proponent of dynamic VLANs because of the extra security added. All that would be needed is to hire a couple people that, when a new NIC or laptop comes into the company and passes through your department, they add the MAC address to the database and assign it a VLAN.
That way, your users are free to roam the corporate network while maintaining their workgroup association but even more importantly, MAC addresses that arent in the database (unauthorized NICs like someone bringing their access point from home or their lappy) immediately trigger the port to go into disable mode.
The idea sounds cool, but you'd have to have plenty security guards in something as 'auto'mated as that. Plus, what if someone hacked into the server and decided to "rent" a bunch of nice cars?
Inplantable RFID tags are just not for me. Sounds a little to, well, end-times-ish. I would rather have an RFID watch or something. Sure, it could be stolen, but what about a central control website where if it was stolen, I just deactivate the code from it and put in the code for my new watch. Problem solved.
Although we discuss it some in the networking class at my school, only one person I know uses TokenRing (and they use it at home on legacy machines, not for performance but for nostalgia purposes). Interestingly, they also use BNC-coax cabling for their TR.
IEEE has a 1 Gbit/s token ring standard.
When working with Cisco switches, it sometimes comes up under some option along with FDDI. FDDI is like TK on steroids. Double-direction fiber in a ring with a token to talk. I know more people still use FDDI than TK.
Here in Minnesota, it is illegal for anyone under 18 to drive and talk on their cell phone. But those are cell phones. I don't have to look down and punch in the number because almost everyone with a modern phone has voice-dial.
So if cell phones are dangerous to talk on while driving, wouldn't it be even worse to take your hands off the wheel and navigate endless menus to enter in your destination? Why the heck would you program it on-the-go instead of before you got started?
What they really need is voice programming of the GPS navigation systems. Something where you don't need to even take your hands off the wheel.
On a side note: Looking at TomTom's website, the TomTom GO 700 includes a remote control for use ANYWHERE in the car. Can you say "back-seat driver"?
This precooling... Wont it be uncomfortable for the people inside since you have constant temperature changes? I wouldn't want my place to get super cold in the morning just so that it levels off by the afternoon.
Why not develop some kind of air chamber that could be installed in a building that is insulated so air could be cooled off-peak but then released on-demand? Or maybe a pressurized tank?
I do have to agree with the R&D years ahead of time thing. My dad works for Honeywell Defence and Space Center and they are the ones that make the processors for stuff like this.
Shocked one time to find out that a new sattelite was going up with a years-old PPC processor running at something crazy like 333MHz, I asked him what all this was about.
Apparently, to get these chips made, they have to wait until Motorola releases a processor. Then they get a contract from the military. So they take the current processor and spend years taking it from consumer-grade to military-grade and Rad-Harding the chip. Then once the part is done, they put it in the probe which is still a few years from launch. All in all, you have a minimum of a 5 year technology gap for what is going up and what is current.
You have to wonder why, with such a long journey, they didn't try out an ion engine. Sure, it would have cost more, but it would have been able to get there a lot faster. The ion engine has a much higher specific impulse than conventional rockets but are only effective over long range where the engines can be fired continuously. What longer range than Pluto? Plus, include a larger Plutonium core and run several of these.
Sure, it is the fastest probe to escape from the earth, but why not strap on an extra stage and get that baby really cookin!
It will be interesting to see if this drives down the cost of RFID keys for cars (as mentioned in the article). Right now, Chrysler wants a couple hundred bucks for a copy of the key to each of my cars. I cant just head to Walmart and get myself a fifty cent copy.
You have to wonder what means of database management they use to keep all this data. We're not talking about a small company access database here.
It would be interesting to konw how their server setups are to hold this data and how they process all of it should it ever need "re-indexing". Just imagine that processor load!
Remember, though, that these artificial retinas will have some sort of computer control and some kind of programming. Lets sure hope that these things don't have a live-update feature for the software because that would mean a non-local connection. That'd lead to vulnerabilities. Just imagine your vision not only lagging and causing you pain, but it being used to carry out a spam attack.
Lets hope M$ doesnt make any software for these things. I don't want to load "critical updates" into my eyes.

No... Not a VLAN for every MAC. You have your VLANs and drop the new NIC into a bin for that VLAN.

What will happen to these sharks if they can't eat? They have to have an off-button so that the shark can go back into normal shark mode.
Someone will jam the signals used to control the sharks and then you'll have an immobile shark.
This reminds me of that terrible movie "The Final Cut".

Well, according to Wikipedia, It is estimated that the print holdings of the Library of Congress would, if digitized and stored as plain text, constitute 17 to 20 terabytes of information. Remember, this is without images or diagrams. Just plain text.
So this is roughly the size of the TEXT in the library of congress.
