IBM Solar Concentrator Can Produce12kW/day, Clean Water, and AC

dfsmith Re:OK (268 comments)

So figure this thing can be built for 20k. And you manage to save $1k a year. It will take 20 years to pay off...

That's at $0.05/kWh. In California the CPUC demands $0.34/kWh if you run more than 4 light bulbs.

Now That It's Private, Dell Targets High-End PCs, Tablets

dfsmith Re:board of directors is the problem not Wall Stre (167 comments)

Apple is somewhat special. See, for example:

Institutional ownership of Apple shares has declined as funds question the company’s ability to increase revenue long term, Morgan Stanley said in a report this week. Apple’s 30 largest shareholders own a record low 30 percent of shares outstanding, down from a peak of 40 percent in 2009, according to the report.

Now That It's Private, Dell Targets High-End PCs, Tablets

dfsmith Re:board of directors is the problem not Wall Stre (167 comments)

Boards are typically appointed by the shareholders. A large proportion of shares (majority?) are held by "Wall Street" as part of mutual funds, etc.

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.

dfsmith AT&T executive 45mph speed limit (533 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?

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!

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...".

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.)

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."
