Direct Sales OK Baked Into Nevada's $1.3 Billion Incentive Deal With Tesla

dfsmith Re:Suercaps (149 comments)

Using wikinumbers, here are some relevent energy densities.

  • Li-ion battery: 100 to 265Wh/kg (900 to 1900J/cm3)
  • Supercapacitor: 0.5 to 15Wh/kg (no volumetric density easily obtainable).

Here's a press release from some company that claims 60Wh/l (~200J/cm3) from their research supercaps.

AT&T Says 10Mbps Is Too Fast For "Broadband," 4Mbps Is Enough

dfsmith AT&T executive 45mph speed limit (528 comments)

How can we mandate that AT&T executives must not drive faster than 45mph, which is as fast as you need to go to get basic transportation?

Tesla Plans To Power Its Gigafactory With Renewables Alone

dfsmith Re:WIl they use my tax money? (260 comments)

You need to feed your horses better. It's closer to 750W. ;-)

(33,000 ft-lbf per minute -> 745.7W.)

Ask Slashdot: Best Service To Digitize VHS Home Movies?

dfsmith Re:dv camcorder (130 comments)

Every digital format is lossy compared with the analog source material. As long as you only lose the noise part, you can reasonably call it lossless. I think the analogy is more like:

  • "Where can I find a good semi-freestone peach pie?"
  • "The place over there does a great clingstone peach pie."

How Astrophysicists Hope To Turn the Entire Moon Into a Cosmic Ray Detector

dfsmith Re:mini-explosion? (74 comments)

I did some quick calculations, and (1e20)eV is a 145g baseball at 54km/h. Not nearly so painful as 100kph. Now, in terms of a hyperdermic needle (1g) it's about 400mph. That'll hurt!

dfsmith Re:Prevent damage to your computer (169 comments)

Maybe the engineer was anxiously looking around for flying chairs coming from Balmer's office?

Steve Ballmer Authored the Windows 3.1 Ctrl-Alt-Del Screen

dfsmith Re:Bastard! (169 comments)

... always shut down your computer by selecting Shut Down from the Start menu.

You've got to admit, the advice is sound. "I see you tried to run a program. Sheesh. Remember ALWAYS shut down your computer...".

No, a Stolen iPod Didn't Brick Ben Eberle's Prosthetic Hand

dfsmith Mythbusters (122 comments)

Maybe the hurried journalists quietly noted that there are now 66% fewer Mythbusters and thought, "Let's run with it—what's the chance of being caught now, eh?" B-(

Seagate Ships First 8 Terabyte Hard Drive

dfsmith Re:if 1 drive full, raid. Dual read write armature (316 comments)

Like this one?

In a nutshell, the smaller production runs make this type of drive more than twice as expensive as two regular drives, with similar performance for independent workloads. (But if you have a particular workload, you may benefit.)

Gas Cooled Reactors Shut Down In UK

dfsmith Re:not big in UK (120 comments)

'Renewable' fuels are a misnomer. The sun will run out of fuel too sometime.

But the sun is renewable. Where do you think our current Sun came from? Recycled stars.

Why the "NASA Tested Space Drive" Is Bad Science

dfsmith Re:The Relativity of Wrong (315 comments)

Clearly mountain climbing bends straight edges; because the horizon is flat* at the bottom. Maybe it's a property of wood at high altitude? B-)

* Well, bumpy. With trees and (probably) mountains too.

Laser Eye Surgery, Revisited 10 Years Later

dfsmith Re:Astronomy, and general poor night-time results. (550 comments)

Don't use a black background. I find bright cyan (#00FFFF) background with black foreground works well for my eyes. Other people think I'm crazy though. (My eyes have intra occular lenses in, due to early cataracts. I told my son I got robot eyes. 8-)

Ode To Sound Blaster: Are Discrete Audio Cards Still Worth the Investment?

dfsmith Re:They have a great fab process (502 comments)

You have to wonder why they couldn't push the S/N from an awkward 19.49dB to a nice round 20dB improvement.

Unofficial patch extends Windows XP support

dfsmith dfsmith writes  |  about 6 months ago

dfsmith (960400) writes "Many companies, my employer included, have stopped supporting Windows XP starting today. Luckily, a couple of engineers at Microsoft have released simple patch to extend XP support. "Our patch extends March indefinitely. For example, with the patch, today is March 32nd. And we wish you Merry Christmas later this month, on March 300th!", explained Rolf Paoli. Seems like an ingenious way to fix an awkward problem."
