The Importance — and Limits — of Very Large Data Sets

zMaile duh? no, needs more than that... (17 comments)

I was originally going to just say 'duh', but I guess it's something that a significant proportion of people may overlook. The analyst needs to have as much of an impartial view as possible to give data that is as unbiased as possible.

Facebook Data Collection Under Fire Again

zMaile Re:Is this the government's job, though? (49 comments)

My thoughts exactly. If we want a truly free internet, with that comes the ability for any website to be able to do whatever they want with their site. If that included adding a facebook 'like' button, then so be it. It's their choice. Unless i'm missing something...

Sony Delays PlayStation Network Reactivation

zMaile Re:Who & Why (317 comments)

Except a black hat doing it for 'hactivism' isn't going to give sony any hint of who they are. No sense showing pride to the world when you've acheived your task anyway.

Electric Car Goes 375 Miles On One 6-Minute Charge

zMaile Re:Too good to be true (603 comments)

batteries actually currently take 4 hours to charge. the 6 minutes is theoretical limit. does that make it seem a little less 'too good to be true'?

Electric Car Goes 375 Miles on One 6 Minute Charge

zMaile Re:I hope this goes into production (2 comments)

It may still not be compeltely acceptable for long distance travelling. The battery takes 4 hours to charge. The 6 minute figure comes from the theoretical limit that hasn't actually been reached. Quoting Neil Blanchard from the linked article:

Yes, I agree the car is not super efficient, but the battery seems to be the revolutionary thing.
If this is real, then the end of the ICE age is here.
They are also saying the batter is 97% efficient, which a bit better than current batteries (which are ~94% as I understand it?).
They had ~18% charge left, and since we don't know what the DOD is, a wild ass guess is they used ~90kWh, and this works out to ~240Wh/mile. Which is very plausible, though not outstanding. At 660 pounds, this battery could be used in Dave Cloud's Dolphin and since it is 1,300 pounds lighter, it could get below 100Wh/mile -- and have a range of about 1,000 miles!
*That* would be a revolution!

"Technical Data Audi A2 DBM *
* Subject
Empty weight (including driver) 1260 kg
Perm. Total weight 1600 kg
Battery lithium-iron-polymer (260 Ah/380 V) cell voltage of 3.8 volts
Battery weight about 300 kg
Charging time about 4 hours due to mains phase current in the household (380)
battery requires 6 minutes (future solution)
Life time 2500 charge cycles (without loss of capacity)
= Service life target: 500,000 km
Top speed 160 km / h
5-speed sequential gearbox (race gear: shifting without the clutch)
E-motor 300 Nm torque"
So, the 6 minute charge is future/theoretical limits of the battery. The actual time is 4 hours; which is still very impressive.
Sincerely, Neil

Why Are We Losing Vertical Pixels?

zMaile Re:Dual 960x1080 (1140 comments)

You're reffering to Linux right? or possibly OSX? Windows aero has that snap to left/right side of the monitor that works well with 16:9, or even two monitors. I'm not trying to troll, and i know it's possible to set up linux to do a similar thing (I used compiz, but that has its issues too). I dont have any experience OSX, so i can't comment on that. As far as i know, windows does widescreen best, at least by default. Personally i hate M$, and all their practices, but i'm not above saying what they actually do well.

Texting On the Rise In the US

zMaile 50 messages a day? (468 comments)

Is that taking into account messages over 160 chars that are broken into two or more messages? Just a thought. In australia, i dont know of anyone that sends that many messages a day. The heaviest message-er (18 years old) that i know would only send about 20-30 a day.

4chan Gives 90-Year-Old Vet a Great Birthday

zMaile Re:Wow (363 comments)

Anon isn't one being, it's a collective of people. Some are nice, some aren't, and some do kill puppies and post that as an animated .gif. Though recently 4chan got a bunch of 'summerfags', who i imagine are diluting the truly 'evil' anons that there are. It really has been getting more immature and the years pass by.

Filmmakers Resisting Hollywood's 3-D Push

zMaile Re:Simple explanation (521 comments)

I don't think it would be too hard to smuggle a camera in with a circular-polarizing filter in it. And wouldn't it take alot more effort (i.e. money) to make the movie 3D? Not that i dont think the RIAA are the scum of the earth...

Attacking Game Consoles On Corporate Networks

There is the issue of alot of games requiring another console to connect to to play multiplayer (which i'm assuming is what you mean by team-building).

Caltech Makes Flexible, 86% Efficient Solar Arrays

zMaile Re:I think its entirely reasonable to say... (439 comments)

I'm not 100% sure, but if 78% of electrons generate electricity, isn't there still wasted energy before it actually gets to the useful energy stage? i.e. energy in a single visible photon (~700nm if i recall) is significantly higher than the energy required to jump an electron up a state, and that difference in energy is turned into heat. this would have the effect of reducing the overall efficiency to 15% or something that is much lower. Is this true, or am i remembering bits and peices that are all wrong?

Microsoft Kills 3-App Limit For Windows 7 Starter Edition

zMaile Re:WIndows 7 even more basic ed. (352 comments)

So you're saying that the key to Linux's success is to charge people for it more than win7? To who do the 'donations' go to? A support company?
