Because the energy and CO2 released by the manufactured gasoline were originally captured from the sun and the atmosphere respectively by plants. Thus the net effect over a very short cycle is zero.
The liquid lens just allows refocusing by changing the shape of the lens. There's no benefit in high-aperture telephoto, which seems to be the main benefit of this new lens.
Basically, the benefit of this new technology is that if you want a longer focal length for the same aperture, you make the lens *wider* but not longer, making it suitable for telephoto or wide aperture photography where bulky lenses can't be used. i.e. compact cameras or cellphones.
Personally, I saw the drawing and recognised the concept immediately. All they've done is taken the reflector lens concept and extrapolated it. So simple anyone could have thought of it. But nobody did.
I'm not really looking at Linux as a viable alternative, especially for the missus!
I was more wondering how smooth a transition from XP to OSX would be
Add to that the fact that if I buy a windows machine now it comes infected with Vista, but if I get a Mac I'll have to pay to upgrade to Panther in a couple of months
Actually the BBC micro and its cut-down counterpart the Acorn Electron preceded RISC processors and ran a 'basic' OS, (MOS/BASIC) that was little more than a tape filing system and a BASIC command line.
A pretty good one for its day, I have to admit.
It was followed by a disc filing system they simply called "DFS", and then later progressed to a directory-tree system called "ADFS"
It was Acorn, the manufacturer of these computers, who went on to develop what I believe is the first RISC processor, the ARM, and made a line of computers based on these with RISCOS for many years
My motherboard just died on me in such a way that I ended up killing my WindowsXP installation trying to recover from what I thought was a driver problem.
The Dual Opteron246 Tyan I was running it on has been unstable ever since I moved house and I'm sick of it. My wife's laptop got a broken screen at just about the same time and I immediately bought a replacement, which I have yet to set up.
I'm thinking, Do I really need Windows anymore? Both Linux and OSX can run many Windows programs on the desktop, but I'm still not sold on Linux as a home desktop OS.
Macs are fast, cool, and if you stick with 3rd party upgrades for memory and drive space, they're not too badly priced at the high end. I'm thinking I should take back the laptop I bought for my wife and get her a MacBook. All she does is internet, mail, print postcards and manage family photos and her blogs.
Then I can replace my Big Rig with a Mac Pro on which I can do all my stuff: Number crunching with Mathematica, Photography, Family videos, music production (cubase)... All that stuff will work.
What do I lose?
Lots of free VST instruments which are Windows only. -- sad but I'll find replacements.
True Excel functionality -- I use a lot of add-ons such as Bloomberg price feeds that I'm not sure would work. Do I really need em? I'm not sure.
Warez. -- I'm no warez junkie, I buy most of the commercial programs I use, but it's very convenient to be able to find copies of software to try out or use for a one-off I would otherwise never pay for.
Can I manage my home network as well? I have a large video and music collection on a Terastation, I hear Mac users sometimes have problems playing.AVI files, and right now there is *no* way to play AVCHD files as produced by my Sony HD cam. OK I'm sure this will be addressed fairly quickly.
Can any/.ers put my mind at rest on any of these issues, or perhaps point me in the direction of some resources to ease the transition? Otherwise are there any/.ers who did "switch" and wish they hadn't?
The point is that Moore's law is enabling flash drives (as well as HD storage) to get cheaper at an exponential rate which is faster than the size required to hold an OS is growing.
$600 is a lot for 32GB, but 32GB is already enough to hold an entire OS and applications suite for many people. There are already plenty of people (professionals) willing to pay that $600 for the priviledge of storing it on flash.
When 32GB costs $100 in flash, however little it costs on disk, the latest version of your favourite OS plus apps may take up 60GB, but then you'll have a 64GB drive for less than $200. A premium even I'd pay, no matter how cheap HD media is.
It's an amusing possibility. Indeed, it would be the free-market's way of legitimately selecting candidates based on age/gender/race while remaining underneath the legal radar.
Or rather, it may be the free market's way of legitimately selecting candidates that are the best for the job, without having to venture into un-PC selection policies
I can't see how this process would *not* discriminate for bias with race, social status, or gender. Just as insurance companies are allowed to discriminate for those things when setting policy premiums, this process may force society to accept discrimination in the workplace by showing that the factors *do* have legitimate consequences
Whilst I'm no fan of PC anti-discrimination, I'm not sure I like the way this is going
The solid-rocket propelled "torpedo" achieves high speeds by producing a high-pressure stream of bubbles from its nose and skin, which coats the torpedo in a thin layer of gas and forms a local "envelope" of supercavitating bubbles
Gas. Not vacuum. The first thing I thought when I heard about the Shkval is "I wonder if the technology could be useful at ship-sized scales?", the first thing I thought when I saw the article here on slashdot was "Woo, supercavitating!"
I work for a bank. You'd be surprised at the level of monitoring these days. Particularly because employees are under instruction not to inform you of any suspicion they may have, for fear of alerting a potential criminal that his game is up.
You may not consider wikipedia 'credible', but a google search for "suspicious activity reporting" or "Anti money laundering guidelines brings up a wealth of credible documentation. I just linked to wikipedia because the information was presented in an easy to digest format.
If the nanotube itself is the strongest part of the system why weaken it by welding it to the tungsten?
If they can manipulate objects at such a scale, They would surely get much better results by tying the nanotube to suitably shaped anchors.
Off the top of my head, a bowline would be a good start, I'm sure some slashdot sailor could suggest a loop knot or hitch more suitable for a slippery line.
Most people who say this are used to mp3s being low quality. I too can easily tell the difference when quality is that low.
But for "LAME --preset insane" quality files, which tend to be about 2x the filesize, I've done my own blind tests on high end equipment: i.e.:
Winamp
->Audiophile24/96 sound card
-> Benchmark DAC1
-> Decware Zen Triode Integrated Amplifier
-> Gallo Nucleus Reference II speakers
Or replace the DAC and amp with a Denon AVC-A1SE amplifier (that's a ref. quality $5000 a/v amp)
I've also listened with Sony MDR D77 headphones, and Shure E3 studio monitor earphones with both of these amps.
In my own conclusion I couldn't tell the difference.
I coded the files back to WAV, a mix of high quality recordings of classical, rock, techno and Clapton, and invited a self-professed bunch of audiophiles to volunteer their opinion on which were the true WAVs and which had gone through the mp3 coding process. Nobody volunteered an opinion.
Since then I always code my music to mp3 using that setting. I've DJd using that quality of file with Virtual DJ with no pitch correction (important, this affects quality a lot) and had other DJs tell me they couldn't believe I was not using Vinyl.
I wish I still had the files I prepared, I would post them here for your enjoyment, but I don't doubt some slashdot genius would come back with the correct answers by examining the files digitally.

Almost. But not totally.
One word: "Booyah!"
Seriously, if you look hard enough you'll find it. This is the internet, after all.
Is it just my filthy internet-corrupted mind, or did anyone else immediately think "dog in a bathtub"
No I'm not linking, go and look it up if you must

Simple, elegant, useful. fucking genius.
pissed off at whom?
The people who pulled this 'stunt' in 9 cities, or the people in just *one* city who decided that igniknot flashing the bird was some kind of threat?
Thanks for the info, both of you.

Just how black is black? Is it more black than traditional 'black' such as black paint or charcoal?
I'd also love to see an absorption spectrum for this stuff. Is it black in Infrared, UV, microwave, radar etc.?
