This is not a switch, it's a fan-out device for one-to-many and many-to-one communications. It does not do L2 forwarding, MAC address learning, security, multicast, QoS, or congestion control.
It's only use is for a SINGLE host to exchange low-latency lightweight messages with a bunch of other hosts. 10GE is used for its low latency properties only. In fact, if you actually tried to send any sort of high traffic volume through this mux, it would fall on its face.
Before you do, ask how much bandwidth Cablevision provisions to serve each neighborhood.
A 100 Mbps last-mile connection isn't worth didly-squat if the CMTS head-end only has a 155 Mbps uplink. Even a gig uplink is only enough for about 80 customers, given typical 8:1 oversubscription. Many ISP's don't mind 100:1 oversubscription or worse!
When my son was 2.5, I brought home a throwaway tablet from work. I set it up to launch web sites in "kiosk mode" like pbskids.org and our web photo album. I also disabled right-clicks and some other confusing UI gadgetry. He loves his moments of computer time (a couple sessions per week, max). I always sit with him, and he takes very good care of the machine. pbskids.org has games for all ages. Don't listen to the gut responses here. Anything interactive beats parking your kid in front of Baby Einstein or Disney.
My mistake was thinking that a tablet pen would be easier than a mouse! That pen requires steady hand that can be frustrating, even for me! When he got his hands on a mouse and tuxpaint, it took him about 2 minutes to master.
The future has great promise with touchscreens. I looked at the HP this year, but it looks like touch support beyond the built-in HP apps might be poor. I'm holding out for an Apple touch tablet!
At least one other "old" news story made it to Google News yesterday. At about 7AM PDT on Sept 8, 2008, the headlining link for the RealNetworks DVD ripping story was to a 3-year old PCWorld article entitled DVD Ripping Flourishes. That old article had a correctly dated byline and appears to have been scooped up by Google at about the same time as the United Airlines Bankruptcy article (10:30pm PDT the night before).
Also on Sep 8, Google news introduced a new feature that returns old archived news stories to be returned in news searches. Is that a coincidence or what?
Google's official answer on the subject avoids any sort of culpability. Did anyone else come across new "old" news on Monday Sep 8 on Google News?
Back in the days of BBS's and chat-lines of the late 80's, a we'd do this to people who were too cocky or creepy:
bee> do you want to increase your connection speed?
fng> yea!
bee> turn on your modem's T117 multiplexing
fng> how?
bee> try "atm0d9t117*,,,;z" for an modem init string
fng> brb.
fng has logged off
fng has logged on
bee> is it faster?
fng> it seems to be a few minutes go by
fng> you asshole!!!!!
If you know your Hayes "AT" commands, that command silently dials 911, hangs up, and then allows another call to take place.
It was no great hack. It was cruel and sophomoric and I regret it now. But there's a demented cleverness to it that still gets a chuckle.
And it's a far cry away from "swatting" of the article.
Four of five of my local analog channels are UHF and, as I said, the picture may occasionally show light static or ghosting but it's still very watchable. As for your seeming disdain for my competency, it only helps focus two of my main points:
The 50 million Americas who rely on analog OTA as a primary or backup medium are, over the next 13 months, expected to not just buy more equipment, but also to become RF experts and perform non-trivial antenna installations in order to continue watching the free television.
The digerati can't fathom the burden this places on the rural housewife, the grandma in a retirement condo, the hispanic family living month-to-month, the apartment dwellers who can't install exterior antennas, the Wyoming rancher, and so on...
These people do not deserve to be left in the dark.
You did make one interesting point -- that some UHF stations will transition to VHF after the 2009 transition. This is true, but hardly sweeping. According to FCC DA-06-1082A2 (http://hraunfoss.fcc.gov/edocs_public/attachmatch/DA-06-1082A2.pdf), 262 stations will switch their DTV broadcasts from UHF to VHF on Feb 17, 2009. However, the final count of 482 VHF DTV stations will still be far less than the current count of 718 VHF NTSC stations.
It's also worth nothing that few DTV broadcasters use low-band VHF (channels 2-6) because of widespread reception problems (http://www.tvtechnology.com/pages/s.0001/t.1169.html). If that spectrum is mostly avoided by DTV anyway, what'd be the harm in assigning it for continued analog broadcasts?
Lots of people in areas that got nothing on analog are getting perfect signals as soon as they switch to a digital receiver I cannot believe that unless those people live in places without trees and perfect weather (i.e., Southern California), or unless they are also installing new aerial antennas.
I've tried to use OTA DTV for the past two years. Usually it's great, but the signal dies in even marginal weather (the so-called "digital cliff"). I live within 15 miles of the broadcast towers. I've tried powered, directional antennas and mapped out the best orientation for each signal. I've tried outside antennas in different places. Nothing has helped. From what I've read, the only solution is to erect an antenna taller than the nearby trees -- and that's still no guarantee.
Analog TV has always been the old reliable standby. Crouched in the basement with tornado sirens blaring, you could always get a fuzzy picture with reasonable audio even if you were 50 miles from a broadcast tower.
Who is looking out for the public interest? What about the 22 million people relying on analog OTA as their primary television reception? What about the 28 million digital satellite subscribers who use analog OTA as a backup when their satellite signals go down?
The biggest proponents of the digital OTA change seem to be...
digerati who don't use or care about analog OTA and who are drooling over the prospects of spectrum reuse
government who has already spent the revenue from the spectrum auction
the cable companies, who see this as a windfall (buy cable stock if you can; 2009 will be their best year ever)
I find it ironic that the analog OTA retirement is snuggly wrapped in a blanket of post-9/11 patriotism since some of reclaimed spectrum will be used for emergency communications. In fact, analog OTA retirement will shutter the most successful and widely-used emergency broadcast mechanism history has ever seen.
Maybe if every member of congress should be forced to switch to digital OTA....
Web developers would do well to study existing web acceleration products to see how they work -- they go far beyond gzip and many of their optimizations can be implemented locally.
Wargames had its problems, but I agree that it captured more of the spirit and methodical approach to hacking that most any other film out there. It certainly inspired a huge legion of real hackers and has added terms like "war dialer" into the lexicon.
The voice synthesizer was Votrax, which was available as a hardware device with an RS-232 port (http://www.redcedar.com/sc01.htm). It would say whatever it saw on the serial port -- e.g., from a terminal programs log or print feature. I wanted one so bad, but couldn't afford the $300 back then.

E.g., Cisco's AVS (formerly Fineground): http://www.cisco.com/en/US/products/ps6492/product s_white_paper0900aecd80321a32.shtml
- implements the multiple DNS name solution suggested by Mr Hopkins
- has a clever way of eliminating browser cache validation requests
- has a mechanism to transparently measure actual (not simulated) user page load times
