Re:AC?

On: How to Reach 200 MPH on Hydrogen Fuel Cells

Probably for the same reason that Toyota chose a permanent-magnet synchronous that runs off of 500V DC for the Prius. Six big honkin' IGPT transistors convert the DC voltage to 3-phase AC with pulse-width modulation and variable frequency control.

Re:telnetd NOT on "by default" in Solaris 10

On: Solaris Telnet 0-day vulnerability

This looks like a non-issue to me, but I certainly could be missing something... If you can log into a non-root account without being prompted for a password, it is an issue. And it is. I did have to "svcadm disable telnet" on all my Solaris-10 systems.

Re:1.2 Megawatts

On: 500 Miles on a 5-Minute Recharge?

Passing that in 9 minutes gives you an average rate of 1.2 megawatts. What the hell knid of household has the circuit to handle that?

Clearly each car will have to come with two ultracapacitors. The one that stays at the house can take its time recharging; a 10-hour recharge time using 20 amps at 240 volts is not unreasonable. The stationary ultracapacitor could recharge the mobile ultracapacitor quickly using thousands of amps, and not even make the lights in the house flicker.

Re:What is new here?

It records OTA and digital cable. The box you have cannot receive HD from cable TV, this one does. http://www.tivo.com/2.0.boxdetails.asp?box=series3 HDDVR&plan=prepaid3yr

Re:Compatibility

On: TiVo Announces High-Def Series3 DVR

Will the new Tivo act as a secure recipient of HDMI content or does it even have HDMI in?

No, it does not have HDMI in. The only input is coax coming in from the cable TV company. The device has up to two CableCARD tuners so that it can record digital cable TV channels.

IBM WebSite say that it born on August 12.

On: How the IBM PC Changed the World

That site clearly states that the Press Release occured on August 12, 1981. http://www-03.ibm.com/ibm/history/exhibits/pc25/pc 25_press.html and http://www-03.ibm.com/ibm/history/exhibits/pc25/pc 25_birth.html

On August 12, 1981, at a press conference at the Waldorf Astoria ballroom in New York City, Estridge announced the IBM Personal Computer with a price tag of $1,565.

On: D-Link Settles Danish Time Dispute

for as long as the Danes were willing to point the DNS entry for that server to them.

If you RTFA, you'll see that the devices in question are not using DNS. They are using a hardcoded IP address, so DNS would not solve this problem.

Re:Different dataset from Keyhole

On: Google Adds Satellite Imagery to Maps

Looks like, at least in parts, the imagery is from an older dataset than what's on the Keyhole service.

Check out "1600 Pennsylvania Ave, Washington, DC".
The details about the rooftops of certain buildings have been censored. (Not that I blame them.)
