  1. Re:Cost is the issue on Solar Cell Achieves 40% Efficiency · · Score: 1

    It sounds like an automatic tilting system could be quite cost effective for these.

  2. Re:transport losses? on Solar Cell Achieves 40% Efficiency · · Score: 1

    There was a skit on a Bosnian SNL-equivalent making fun of computer science education there. The teacher was shown in front of a blackboard on which she drew a huge keyboard with chalk, and proceeded to tell the kids about function keys, etc. The kids were frantically copying everything down ;)

    If 10% panel = $100 per Watt, then 40% panel = $25 per watt.

    The 7% raise is fine. The raise I found objectionable was that which is high enough to discourage domain squatting. How would you like to pay, say, 4-digit registration fees? Think spectrum licenses.

    If there was nowhere for you to go, that is that. But if there was, you could've moved forward, and in case he did try to stop, maybe avoided the accident or at least reduced it. Granted, this kind of defensive driving may only help avoid a small fraction of accidents; and given that accidents are rare in the first place, probably doesn't reduce the overall accident count much. I'm a control freak though, and that's how I drive :)

  6. Re:Tailgating on Detecting Tailgaters With Lasers · · Score: 1

    Both his sides were clear; he didn't say anything about pedestrians, so if there were none, there should have been enough room to either: move ahead enough to let the kid grind to a stop; pull a sharp turn; or, in the worst case, briskly merge into the cross-traffic. I usually stop short of the line to allow room for this.

  7. Re:Moo on Detecting Tailgaters With Lasers · · Score: 1

    I loved driving in Italy. There is an orderly highway culture where people automatically yield the left lane as soon as they see someone approaching from far behind. The cutest example of this I witnessed was when I yielded to a VW Golf. The Golf yielded a minute later when a BMW closed in; finally the Beemer yielded when flashed by a recent Boxter. All this while I was doing 94mph!

  8. Re:Tailgating on Detecting Tailgaters With Lasers · · Score: 1, Insightful

    This is why you always always always have to pay attention. Assume the car approaching from behind will not stop. You probably could have avoided that accident.

    Yeah, raise prices! That way we can get rid of all those junky hobbyist and personal web sites, and ensure that only high-quality, well-produced sites can stay in business, like cnn.com, verizon.com, amazon.com, etc.</cynical>

  10. Weather stations on BBC Wants Evidence of Climate Science Bias · · Score: 1

    I've been to central Mexico last summer, and I wondered why all the remote temperature sensors were sitting next to hieroglyphics-branded AC units.

  11. Re:BitTorrent for commercial content distribution on Bram Cohen on BitTorrent's Future · · Score: 1

    It's like this. Suppose there is a company A, selling downloadable movies hosted on their own servers, at price $A, and company B, selling movies distributed over bt, at price $B. Suppose it costs you $C dollars of bandwidth to use company B's offering. Now, presumably company B will be able to offer its product at a lower price due to the negligible bandwidth bills; and if $A-$B > $C, then it's clearly beneficial to go with B even if you use up your own bandwidth. Clear?

    Tubes, of course. That reminds me of an alarm clock I saw in a Walgreens that had 4 vacuum tubes on one side. I couldn't believe my eyes! I took a closer look, and found that the tubes were plastic with LEDs inside to simulate the orange glow ;)

  13. Re:common Nyquist fallacy on Does Portable Music Have to be Compressed? · · Score: 1

    The problem with your argument is that the changes of frequency show up as high-frequency components in frequency domain. Try looking at some power spectra of such signals. Therefore, the Nyquist theorem still stands, it's just that the cutoff frequency is much higher.

  14. Re:FFS shut up already on Does Portable Music Have to be Compressed? · · Score: 5, Funny

    I'm with you on this one. Even CDs are inferior to studio tape when I listen to them on my magnetically levitated speakers hooked up to the stereo with gold-plated cables. The tape heads are gold-plated too. The whole setup sits atop a few tons of sand bags and is located in an underground chamber enclosed in a steel Faraday cage.

  15. Strawman on Experts Say Ajax Not Inherently Insecure · · Score: 2, Interesting

    Way to make up an issue and then show off attacking it.

    What gets me is that he was able to sniff the president's login and password off a LAN. Seems like they need to do some work on their intranet security.

    Guys, it's called the rule of law and every civilized country out there has figured out why it is important.

  18. Re:Use a bit of care... on Why Do Gadgets Break? · · Score: 1

    I live in Boston, plenty of salt in the winters. I guess our definitions of "everything" differ, because the only place salt ends up here is outdoors, near high-traffic areas that kick up the spray.

  19. Re:Use a bit of care... on Why Do Gadgets Break? · · Score: 1

    By the time you create the watertight case, create a new cooling system decoupled from the inside, solve the sealing issues (resistance to salt, moisture, prevent temperature swings from sucking in corrosive vapors from the outside), redesign the I/O connections, etc. you will have a ruggedized product that costs much more.

    If the market really wanted this kind of box the ToughBooks would be cheaper by now.

    I think the best in-between solution you mentioned elsewhere is keeping the thing in a watertight box to prevent flooding. Otherwise, just live with the spray. (Perhaps there is a liquid cooled box somewhere that doesn't circulate outside air across the insides. BTW when worrying about corrosion I had in mind the electronics, not the outside).

  20. Re:Use a bit of care... on Why Do Gadgets Break? · · Score: 1

    Unfortunately, salt water is one of the most corrosive outdoor environments, much more so than fresh water. Of course the laptops on the mass market are not built to withstand it; it would be expensive and few customers would benefit. Specialized uses call for specialized solutions; for marine use you should probably look into ruggedized products.

  21. Re:Use a bit of care... on Why Do Gadgets Break? · · Score: 1

    And if I buy a laptop, it should survive a little rain, being dropped on concrete, being dropped in salt water, having someone fall on it, etc, all common things happening to transportable items.

    With you until "being dropped in salt water." WTF???

    The real problem is convincing people that preventing global warming matters. So what if a bunch of coast floods? Humanity has lived through worse. I say bring it on!

    Before someone complains that ARP only works for addresses on the same subnet as the original host (which amazon.com wouldn't be) let me point out the missing first step of making your PC think my PC is the default gateway, which means my PC gets to respond to DNS lookups, which means I get to tell your PC my PC is amazon.com.

    It seems that an access point could easily defend from this attack by validating the destination IP addresses, instead of just blindly switching by MAC address. I wonder if we will see this "feature" talked up by AP vendors.
