You're Doing It All Wrong: Solar Panels Should Face West, Not South

PaulBu Wavelength matters too? (327 comments)

My first though without even reading the summary:

Of course pointing it to the South would "catch" more integrated spectrum, but not all of that can be converted to electricity efficiently (they are more efficient for longer wavelength), so it should not *hurt* much to till them westwards (or eastwards), where/when blue light ("useless for") is filtered by the atmosphere...

By the way, blue light is still absorbed/heats/damages the cells, but not gets converted to voltage. Or some such... ;-)

Aligning with peak demand might make more sense though.

Study Shows How Humans Can Echolocate

PaulBu No, that was stereo hearing (136 comments)

There is a reason we have two ears -- to be able to distinguish the direction the sound is coming from!

But it is not actively clicking and listening to the echo (though probably it would work much worse for a blind person who is also deaf on one ear!)...

The UPS Store Will 3-D Print Stuff For You

PaulBu Remind me to start a company... (144 comments)

Remind me to start a company specialising in generating 3D CAD models of custom dildos! :)

By the way, have they figured out how to print softer, rubber-like materials yet? I have an idea of a sister company too...

Congress Can't Make Asteroid Mining Legal (But It's Trying, Anyway)

PaulBu Moon is a harsh mistress... (213 comments)

I would say that an entity that managed to get there and posess some mined material up the Earth gravity well can probably deal with attempts to de-legalize it rather efficiently. ;-)

Seagate Releases 6TB Hard Drive Sans Helium

PaulBu ~1000 *Bits* per square inch? (147 comments)

I thought that in 21st century we are talking about Gbits/inch^2, not just bits...

New Headphones Generate Sound With Carbon Nanotubes

PaulBu Re:Yes, but... (102 comments)

Could be nice way of sidestepping the Chinese and their "rare earth" near-monopoly.

Judging from the author's names and affiliation, I quite doubt that it was their main motivation... :)

But, it's still VERY COOL!

Keeping Data Secret, Even From Apps That Use It

PaulBu And, SElinux was given to us by which org? ;-) (59 comments)

I think it was in the news recently, a lot, but not for their Linux contributions...

Though, maybe those were referenced too, along with some other contribs to MS, standards organisations, etc.

If anything, I am sure that someone is giving close and fresh look into SElinux parts right now...

White House: Use Metric If You Want, We Don't Care

PaulBu Re:Zero is Still Zero (1145 comments)

'Zero' is still 'zero' whether measured in metric or standard.

Well, no!

Not if you are talking about temperature measured in degrees C vs. F vs. K!

Agreed with the rest of your comment though...

Researchers Report Super-Powered Battery Breakthrough

PaulBu Re:That was the most worthless infomercial ever. (244 comments)

If my cell phone can transmit 30 times farther, I'm guessing that the power will drain from the battery 30 times faster.

Assuming that your cellphone transmit unidirectionally (as it's natural for a cellphone to do!), is not getting 30 times the 'r' requires 'r^2' more power, i.e., your battery will drain 900 times faster? ;-)

Petition For Metric In US Halfway To Requiring Response From the White House

PaulBu Re:US Metric System (1387 comments)

But, 1/32 of an inch is represented *exactly* in binary (0.00001) as opposed to its value in mm (0.11001011001100110011001101), where one little bit past wordlength might, indeed, die... ;-)

Laser Fusion Put On a Slow Burn By US Government

PaulBu Re:Another lie about the NIF (143 comments)

In the context of this article, I misread your last words as "and reigniting our leaders", which might be appropriate too! ;-)

But, I am cheering for General Fusion anyway! http://www.generalfusion.com/

The Trouble With Bringing Your Business Laptop To China

PaulBu Re:Booby trap time (402 comments)

Good idea!

Now, let's try to implement it... I suggest to start with Lenovo laptops, and we only need to outsource USB dongle and exploding battery production somewhere, I suggest China, they have experience mass-producing thing!

Wait! All your matching parts (laptop, dongle, battery) are made where? In... China? ;-)
