compared to the BMW i3
Roughly the same price point, give or take a couple of grand, and the i3 has a range-extender version. Makes the Golf a bit of a hard sell.
Time for the standard fuel cell rant.
The problem is FCV's horrible grid-to-wheel efficiency.
Compared to a BEV, which just needs to account for grid distribution and the round-trip efficiency of the battery, the losses incurred by producing the hydrogen, compressing (or liquefying) it, distribution, and storage all result in FCVs using between 3-5x as much electricity as a comparable BEV - hence 3-5x the CO2 emissions (given the same energy generation mix - in fact it would be even worse because clean energy sources are currently a limited resource).
And that assumes you're getting your hydrogen from electrolysis. Commercial hydrogen is produced from natural gas, releasing CO2 in the process. If you run the numbers on this, it can be shown that FCVs emit more carbon than a traditional ICE car.
The article's not about Google's cars, though; I would be perfectly happy with an article predicting whether they will succeed or not.
The problem is that the author is trying to use his prediction as evidence, to make a wider point about innovation.
I think it would be prudent to wait and see if Google's car succeeds or fails before you use it as the central plank of your thesis..
Re: Is there a rocket scientist in the house?
This is my guess too. Four satellites in elliptical geosynchronous orbits, tracing out the same analemma over Japan, so one of them is always at or near zenith.
If you've ever tried to find a building by its street address in Japan, you'll know why everyone has GPS on their phone.
There are no street names - instead each block has a number, and each house on that block. Except that the numbers are not sequential. With just an address it can be nigh impossible to find somewhere in an unfamiliar area, short of just wandering around and hoping.
Re: Bitcoin is strongly deflationary
"Austrian economics is pretty much common sense when you think about it,"
There's your problem. "Common sense" is not a reliable guide to the functioning of complex systems.
Bitcoin is strongly deflationary
Dabbs touches on this briefly at the end of the article, but this is really the biggest problem with Bitcoin qua currency - even accounting for its vast impracticality.
Simply because it's based on a limited commodity, Bitcoin is strongly deflationary. It's like the gold standard of the turn of the 20th century - there's a reason we invented fiat currency! It's no coincidence that Bitcoin appeals to the same Austrian-economics right wing libertarian cretins as a return to the gold standard.
But I digress. Those of us that grew up in the 70s (or Germans who are permanently terrified of a return to Weimar economics - i.e. the paymasters of the ECB) are taught that inflation is a axiomatically bad thing. This is, of course, bollocks. Moderate inflation is a good thing - there's an argument that our inflation targets should be closer to 4%, not the 2% we have now.
Deflation is crippling - just ask Japan. During deflation, the best thing you can do with your money is sit on it. Investment and spending collapses, and your country enters a prolonged depression.
And if we think we have trouble with an oligarchic elite now, the problem would be so much worse without inflation there to erode inherited wealth.
In short, Bitcoin economics is awful on every level. It's almost as if it has been designed to undermine the ability of governments to control the supply of money and to heighten the power of entrenched wealth (and let's not forget all that lovely potential for tax evasion). And we, the techies, blindly buy into this agenda because it's shiny and new, and has "crypto" in the name, and we think being free from government influence is great when actually it's the only thing keeping the plutocratic wolves from the door.
what you did there..
..I see it.
surely I can be the only one
who feels a bit of pride that good ol' Blighty can mix it with the best of them?
We've all seen this concept before in sci-fi, and every time it involved the trucks being hijacked and looted.
It's a perfectly cromulent word.
I think I've still got mine in a drawer somewhere - don't know if it still works though. I coded up a very simple drawing program to entertain myself in boring lessons, and the program function was excellent for cheating in exams, as the "program" slot could be used to store useful formulae instead :)
"Does this result make Dropbox a viable NAS substitute"?
given that my NAS box has 5TB of data on it, no ;)
what's the fuss?
If you have a passing familiarity with Asian culture, you'll know that in context this is completely unremarkable.
If there's anything here to laugh at, it's that "inori" means "prayer". Which I don't think they've got :)
This reminds me of kickstarter - the "we could go into production if only we had guaranteed orders" thing
I hated yahoo's tabs. My browser has tabs - tabs in tabs is redundant.
Because the bill that established the ACA included its own dedicated funding. Same with Medicare, same with Social Security - they are not affected by the shutdown.
The debt ceiling, on the other hand, is entirely another kettle of fish. http://www.washingtonpost.com/blogs/wonkblog/wp/2013/10/08/a-very-simple-timeline-for-the-debt-ceiling-crisis/
I used Pine up until about 2005, when the company I worked for finally blocked outgoing ssh connections..
The major patents on selective laser sintering run out in 2014. Expect the price to drop considerably - maybe not enough to put it in the reach of a home user, but certainly a small business.
real life continues to imitate KSP
Anyone interested in this should read Ignition! by John D. Clark. It describes the early history of liquid rocket fules, and all their hilariously dangerous chemicals and experiments. It's out of copyright now so you can get a pdf.
Re: Number 4
As a lefty, I'm totally fine with UKIP being a "major political party". Split that right-wing vote, I dare you!
it sounds like a decent first step, but they really need to raise the bar on what's patentable or not - there are far too many "obvious" patents in the system.
free tethering is still a thing (although not for me, as I bought mine unlocked)
according to what I've read, Taranis is not designed for ground attack but for air superiority. I'm not qualified to know how well that works out, but it sounds like a whole different kettle of fish.
nice try, but no. There's a difference between cutting down the parameter space of a theory and testing the theory itself: there's no falsification going on; we're not approaching the "truth" in any meaningful sense.
Eh, chasing SUSY is like playing whack-a-mole. The parameter space is so vast that for every bit you rule out, the theorists can just move their models to a higher energy scale.
"It's one of the "difficult" bits of relativity: even if you and I are travelling in opposite directions at 55 percent of the speed of light, the sum is 100 percent, not 110 percent"
actually, .55c +.55c = .84c

Re: £6.99 ?
apple's mail client handles gmail very badly - doesn't do conversations or labels properly - both of which I can't manage my email without.
I'm pretty gutted by this, as it likely nixes the upcoming Sparrow ipad app.
Well to wheel efficiency
the well to wheel efficiency of an EV is something between 1.5 to 2x that of a petrol car. Even accounting for 20% losses, you still come out on top.
Maths. Use it.
Dropbox - mainly because I've got it already
And it's already integrated with a bunch of my other apps. (PDF reader, Browser for downloading files, Flashcard app, etc.)
Saying that, I rarely if ever use the actual Dropbox *app*, partly because the bundled reader is so bad.
any chance of a roundup of bluetooth headphones? (headphones, not headsets, or those poxy earpieces)
Re: Absinthe makes the farts blow longer
Apparently the BigBoss repro is being hammered and keep timing out. if you keep refreshing it'll download the packages eventually. My iPad required a factory reset the first time as well, but was fine second time round.
favourite JB tweaks:
- Springtomize: allows you to make a lot of little changes to the UI, hide undeletable app icons etc.
- browserchanger: change the default browser from Safari to whatever you want (Grazing, in my case)
- manual correct: no more DYAC!
- cardswitcher: new UI for app switching
- swipeselection: can move the cursor by swiping the keyboard. SO much easier than trying to tap between the right letters
- Retinapad: makes iphone apps look nice when zoomed.
- sparrow+: makes sparrow the default email client and enables push.
still wont play MKVs = still worthless
will it work with FeliCa?
Looks like a video game circa 1990
guys, this news is over a month old. The ICARUS study was published on the 17th October.
years too late
this is all very well, but... I've already got Google Apps and Dropbox. Everything I would want to sync via iCloud is already synched over those services.
If i was a new adopted this might be nice.

your analogue media storage device has a surface defect causing the playback head to seek backwards and read out the same data segment in a repeated fashion.

I know Lewis reckons we should just buy everything from the yanks, but I do think it's worth financing these projects to maintain a domestic technology base; no sense them having all the fun. 150 mil is small beans, in government terms.
enough with the concept cars
put something into production!
god, could they not at least have run it through photoshop to adjust the levels?!

so what happens when missiles become obsolete?
all those expensive carriers with their plane-delivered ASMs suddenly look at bit silly...
I think you're an "ill wave"
"economically useful". And as demand rises, lo and behold what was un-useful becomes useful. Part of the reason lithium deposits are so unexploited is the current sources are so easily available; we've barely scratched the surface on the rest.
@Paul Naylor re: ringtones
your can't use uploaded ringtones for alert sounds such as text messages or email notification, only for the actual phone ring or for alarms etc.
i'm a big fan of electric vehicles, but this is rubbish. They're just trying to dress it up as a serial / range extended hybrid but it's really nothing of the kind. Come on Toyota, why aren't you developing the next generation of technology?!
