Are they even turning a profit at this new price point?
The Playbook does not need to make money. It needs to keep RIM in the corporate conversation long enough for them to make a more compelling argument for their existence. It is a placeholder to keep attention on their real product - the Blackberry brand name.
To make the classic car analogy, it is like when Honda started selling rebadged Isuzu Troopers (Honda Passport). They didn't do it to make money, they did it so they had a "me too!" product on their lot during the peak of the SUV wars while they scrambled to make the real product (the CR-V and then the Pilot).
Simply wrong. One measures film's resolving power in lp/mm (or lines, but many in line pairs). If you don't believe the wikipedia entry on photographic film perhaps Ilford's?
Maybe LEO, but the distance between any two birds in an orbit that high necessitates either one hell of a big bomb or so many nukes one might as well do a direct hit and invalidate the whole shielding bit.
I am unaware of any unique shielding on the GPS birds and can't fathom a viable threat against them. Perhaps there is something in the literature I've missed. I'll ask at work tomorrow.
The problem which lead up to the current 'crisis' is perfectly illustrated through both the arguments of the right and the left as exemplified in this very subthread.
The cause, and solution for, the USA's massive debt load is quite complex and intertwined. Yet all one hears is bullshit simplistic answers which, while appealing to their respective bases, utterly fail to address the problem.
The recent ascension of the Tea Party is a predictable reactionary movement to the fact the world is fucking complex, and only becoming more so. The fact a large percentage of the citizenry is charmed by someone saying "The world is black and white, and here's what I'm going to do" is to be expected. My only fear is a similar movement arises on the left. That said so long as the pendulum is swung in this direction of false monochromatic pandering there will be no long-term solution. The pendulum will swing back, those who rise to power by the sword of simple answers die by the sword of simple answers. When one's charm is "yes" / "no"s it's hard to defend failed decisions with "maybe"s.
It doesn't matter if the metaphorical glass-maker paid the destructor or not. The point of the metaphor is that wealth was destroyed (windows) to create economic movement and how that is a zero-sum (in simplified terms) game.
In the lulz-sec scenario arguably no wealth is destroyed, therefore it is not a zero-sum game.
This isn't the broken window fallacy. Nobody is trying to boost the economy by breaking perfectly good things.
Rubbish. The systems they are targeting are working fine. They are breaking perfectly working things, thus demonstrating that they are BREAKABLE. That's irrelevant. In the broken window fallacy the windows are breakable too.
Wrong.
If the systems they are targeting are breakable they are not working fine.
A window can be breakable and still perform its primary mission. The breakability of the window has nothing to do with the point of the story.
An authentication server can not be susceptible to such attacks while still be considered performing its primary mission.
The fallacy isn't that a person (instead of a force of nature) performed the damage, but rather that money is diverted into replacing perfectly functional things.
A tornado is never good for the economy, for while it may divert money towards the construction industry it has a net negative impact on total wealth.
OP isn't saying a brokerage is better, OP is saying that MtGox and the other exchanges were acting as exchange and brokerages.
Customers are better served when exchange and brokerage are separated and it's a structural weakness of BiitCoin that no method of doing a balanceless exchange appears possible, thus exchange and brokerage functions must be joined.
For me the centerpiece of the OS is the file manager and the tools to do my tasks
This is an argument against the browser as OS and gets +4 insightful? The mind boggles.
1 - File manager as centerpiece of OS: A - A file manager is an app (of my choosing) which runs on top of my OS. B - As we have already seen browser (IE / Konqueror) is hard to distinguish from a file manager (Explorer / Konqueror) and so if we accept your argument that the file manager is the centerpiece of an OS there is evidence aplenty that a browser is said centerpiece.
2 - "The tools to do my tasks" as co-centerpiece of an OS. If ever there was a classic definition of "applications" it was "the tools to do my tasks". The OS is the tool to do the application's tasks. If we're going to zoom out and take such a broad view of what an OS is (it sounds to me like you're describing a desktop environment ) how are current browsers not inches away from that already?
We know the cloud is not 100% reliable
Where in the concept of "browser as OS" is "no off-line content" made explicit?
Because I mined hundreds of them over a year ago (CPU, not GPU mining) when BTC was nothing more than a thought experiment.
I had stopped playing with the system around August of last year and it wasn't until I heard about the price growing past $8 a BTC on NPR that I remembered I had a shit ton of them by current standards.
So I started moving them out through various exchanges, spreading my exposure risk to bad actors and fraud while hedging my bets and holding on to some.

On that very same day, MTGox implemented a $1000 dollar withdrawal limit. Suspicious, right?
Not so. The $1000 withdrawal limit has been in place since at least early May 2011 (when I started cashing out my holdings).
Your definition for wow, flutter, and jitter are too narrow. They are all errors in signal timing.
Who cares if CDs throw out ultrasonics? You keep coming back to this and it is irrelevant. You can not hear ultrasonics. You hear the effects of ultrasonics which are beats and harmonics in the audible range. CDs can capture that perfectly. As I said in the original reply unless we are talking synthetic signals designed to interfere only upon playback the effects of ultrasonics are created in the studio, not your living room. CD delivers this perfectly
No, it does not take cheap turntables to cause noticeable groove wear.
Jitter, wow, flutter, are all the same thing - error in the time domain. Jitter is not unique to CDs.
I'd like to see said square waves, as I implied cutting one is impossible without a theoretically perfect (monopoint) stylus which has no momentum. Forget about even getting close when reading with an elliptical or other stylus of any physical dimension.
You also appear to be confusing where and when the filtering for CDs takes place. I am not arguing 44 is an appropriate sampling rate for recording, but rather distribution. If ultrasonic frequencies causing audible interferences exist in the studio then the audible tones will be recorded and survive downsampling to 44.
As for durability, I can show you the spectrum of a progression of needledrops proving one play decreases HF response measurably and one play with improper (as little as one gram) anti-skate ruins channel balance. Permanently.
They may sound ok to your old ears, but that only proves my point that 44 is plenty for humans.
That's needless speculation. Testing this shit is quick and easy.
A bloody $30 DAP (Sansa Clip for example) can demonstrate better than -90 dB noise floor, better than 90 dB of channel separation, frequency response flat to within a hair of a dB, and distortion numbers which would make an 1990's recording engineer cry.
Fact is competent audio is EASY, and commonly done with the cheapest of components today. I am sure there are examples of failure readily available, for when there are thousands of examples on the marketplace it is no wonder dozens are broken.
Point is your claim of "often" finding broken components is just wrong. Show me some numbers, I can point to hundreds of competent RMAA tests of commodity components and systems to argue my point.
Of course mechanical components are the weak link and always have been. But that's not what you originally said - you proposed that it takes a special amp to enjoy an LP when the amp is far from the weak link.
The frequency response of an LP is grossly overrated. Sure there is 40kHz content possible, the first play, and 40 dB down. Since I rather suspect you can't hear 1/2 that frequency, much less that far down, it is moot.
LP's main disadvantages are: noise wow/flutter (jitter) durability non-linear frequency response If noise was the only one most of us would never have upgraded to CDs.
Your description of how aliasing comes into play is simply wrong, as it assumes improper filtering before sampling. A square wave is nothing more than a collection of sin waves. A 15kHz square wave can not exist after filtering content below CD's Nyquest, and more importantly can not exist period on an LP. I'd like to see someone draw just how a square (or even triangle) wave would exist on a record groove. Bonus points for demonstrating how a non-theoretical-point stylus can track said groove.
If audible tones are affected by supersonic harmonics they were affected in the studio and said effects were recorded. End of story unless we are talking artificially created tones intended to cause interference only upon playback (See The Hafler Trio).
If we are talking supersonic harmonics designed to interfere on playback, ones which did not exist during recording, then we also must assume you have some brilliant speakers to be able to produce these tones in a linear fashion and not just create a bunch of HF noise.
I can show you plenty of LPs with content > 22kHz, but I challenge anyone to show needledrops with signal, not noise, that high.
If we accept that 16/44 PCM is all that is needed for accurate reproduction in sane listening environments (96dB of dynamic range = instant ear damage volumes in all but the most theoretical of rooms) then we must accept that all the "euphoric" distortions of analog/tubes/vinyl can be reproduced with said 16/44 PCM.
Again you are describing mastering preferences not format issues.
Diabetics have higher infection rates because they have worse circulation and lower-functioning immune systems. Neither of which have anything whatsoever to do with this discovery.
Kinematic GPS solves position using the carrier instead of the (time) code. Since the carrier length is ~19cm you're instantly much tighter than is possible solving with the time code.
And, as others above me have said, (regardless if you're carrier or code locked) a 3D solution needs four birds visible because of the receiver's inaccurate clock. At best an atomic clock on the receiver means one less variable to solve for = one less bird needed. Today when we have a full constellation that is just about never a problem unless you're in absolutely horrible terrain with very high horizons, and in that situation your PDOP is going to be so bad as to render moot any positional accuracy gains seen by better clocking.
Not to mention the Russian GLONASS birds up there, and Europe's if they ever get their act together, and the L2C frequency... point is there are lots of inexpensive ways to increase accuracy which don't rely on an expensive clock chip.

*viable threat of that sort

The GPS birds are 12,645 miles up. From that distance the difference between an atmospheric detonation and a surface one is just about nil.
I can't comment on the rest of your post, but if it is as poorly backed as that comment your fears are largely unwarranted.

In this day and age when one can order $0.50 DACs with noise floors 90dB down...
In this day and age when even the $10 CD players at Odd Lots oversample (so as to push the filters into ultrasonics)...
You are describing systems defective to the point one needs to go out of their way to design one with such problems.
If we accept that 16/44 PCM is all that is needed for accurate reproduction in sane listening environments (96dB of dynamic range = instant ear damage volumes in all but the most theoretical of rooms) then we must accept that all the "euphoric" distortions of analog/tubes/vinyl can be reproduced with said 16/44 PCM.
Again you are describing mastering preferences not format issues.
Yea, because the amp is the weakest link in that chain. LOL
This is nothing more than an unsubstantiated claim that LPs are capable of fidelity beyond what 16bits @ 44.1 kHz PCM can deliver.
Where, exactly, do LPs have the advantage?
Diabetics have higher infection rates because they have worse circulation and lower-functioning immune systems. Neither of which have anything whatsoever to do with this discovery.
Except this isn't a problem that needs solved.
