That's one to frighten the granddaughter with...

Thanks for the pointer, El Reg.
It's not providing a simple and documented way of removing them, and in such a way that the basic functionality of the phone is not harmed.
After all, there's a possibility that one or two of them might have some benefit for the user, rather than for the maker.
If it doesn't fit in the back pocket of a pair of jeans, the boss can see it when you disappear down the corridor to the little room with the porcelain chair to, er, consider a tricky software issue.
Indeed; I purchased a fourth kobo (a mini, sadly no longer available) for that very purpose.
Heh. Once arrived at CDG expecting my luggage - an 8' by 6' television reflective backdrop which twisted into a 3 foot circle a few inches thick - to appear on the conveyor.
And waited. And waited. And waited. And eventually got bored and started chasing it. Turns out the bozos had decided to open the package, the backdrop had immediately sprung out to its full size, and they couldn't get it back in the bag...
Fly Fishing, by J R Hartley.
Come, sir! One or two, surely (though I struggle to recall their names).
Though my father, a child of the twenties, maintains that there has been no good music since Glenn Miller died.
So here's a pint to the lads and lasses that kept her flying so long.
Somehow, though, a colour coffee-table ebook doesn't sound like the sort of thing one would leave lying around to impress the casual visitor.
I may be a Luddite - hell, I *am* a Luddite - but to me these are different markets. The books in which *I* am interested contain text, not pictures; and text is an inherently linear monochrome flowed concept. There are some excellent books with non-linear text, and some excellent books containing almost no words, but an awful lot of pictures, and no end of technical books with large and detailed diagrams and other illustrations - but these are edge cases whose use is adequately covered by a robust, reliable, and mature technology: ink on paper, conveniently bound into a 'book'.
Let's not ruin the basic e-ink device by forcing uses other than these text reading functions on it.
You may misunderstand my context, 142... for a final output, surely, use all the bits you can (but be aware of the nastiness of compression-for-loudness).
When I say 18dB headroom, I would expect the nominal zero dB signal to be 18dB below 0dBFS - but I would expect that 18dB to be used by the signal.
In, say, a live studio environment you will find that live voice and music both have level extremes which are generally unrehearsed and, trust me, the last thing you want is digital clipping. In analogue systems the approach was to assume 12dB headroom since an analogue mixer is usually a bit kinder as the signal approaches clipping. However, even there, you are shoving a 775mV signal through amplifiers with at least +/-24 supplies.
In a music recording studio (as opposed to, say, a live concert) you would, I assume, have much greater control over individual levels. Nonetheless, you would generally want a sound mixer with at least 24 bit internal representation, even with a 16 bit input and output.
However, it's some years since I left the BBC so while I have a lot of experience with good studio technique, practice may well have changed since I left. And of course, music recording is a different kettle of fish from live studio work.
Sorry Jeffy! Must try harder... I've only been getting it right for forty years :)
8Khz <-- too fast on the shift key, I reckon.
@142 - 12dB because that's about the minimum you can get away with; 18dB is safer.
@nijam - the S/N ratio gets worse as the signal amplitude decreases because the quantisation noise is constant; 11dB was the average used in the BBC (might have changed since I left).
@John Geek - what makes you think that any sampled signal is recorded with frequencies up to the Nyquist limit? That's why there are brick-wall filters on the input and a reconstruction filter on the output (and no, let's not go into the mess that a poorly designed filter can cause...)
Oversampling at very high rates has one obvious advantage: it makes the necessary pre- and post-sampling filters much easier to design and build.
Don't forget that tape is also compressed, as well as carrying a high-frequency bias signal to avoid the worst of the non-linearity of the magnetic medium.
But your point is valid - if you want a good copy, you get as close to the original as you can.
"you're a bat"
Um, not necessarily. A 24-bit system has a much lower noise floor (or alternatively, a higher headroom) and therefore a greater dynamic range than a 16 bit signal.
As a rule of thumb, allow 6dB/bit for overall dynamic range. Then subtract (at the recording stage) 12dB for headroom an 11dB for quantisation noise - so a 16 bit system, irrespective of bit rate, will have a practical signal to noise ratio of 73dB and a dynamic range of the same order. That's not significantly improved over a 1980s broadcast tape machine, as it happens...
The extra eight bits in the 24-bit system allow an equivalent 48dB improvement in noise or headroom - easily audible provided (a) that your recording front end is both sensitive enough and quiet enough to be effective on close-to-silent signals, and (b) your listening equipment and environment is equally quiet and isolated enough to be able to hear very quiet signals. This is unlikely to be the case outside a professional recording studio.
It's basic theory and practice, yes... but in spite of this, the human ear can only hear those products which fall in the 20-20kHz (or thereabouts, depending on age) frequency band.
If an inaudibly high frequency is heterodying with a lower frequency (whether the lower frequency is within the audible range or not) the only product which will be audible is the difference frequency - the sum will be even further out of the range of hearing.
And guess what - those products are all adequately represented within the basic 'CD quality' signal.
A suggestion: take your harmonics experiment, but set the sample rate as high as you can - 96 or 192ks/s, for example. Now compare a sine and a square wave at 440Hz, and, as you state, you will easily hear a difference since the square wave has a number of harmonics within the audible range.
Repeat the experiment at 4400Hz; you *should* still be able to hear the difference; there is still one harmonic in range, at 13200Hz. Now try it at 8Khz instead, and unless your hearing is exceptional, you will be unable to hear any difference - only the fundamental frequency is within your hearing range: the third harmonic is at 24kHz. And yet it's clearly present in the signal you're listening to.
Googling 'list of delisted bbc pages' takes you straight to the hit, on the third link.
And if so, how does it get it? Inquiring minds want to know - I'm not at all sure how MEMS sensors will work in zero g (though an inertial system might work, if you can cope with the accumulated errors.)
End of life or what? Looks like LittleDiode's rip-off prices for the UK... thanks, guys. Time to replace the huge proms that emulate an ALU.
Yah. But it only appears to be still available in the hot'n'hungry 'LS181 version. :(
That's most impressive. I designed and built a sort-of hybrid 8080/6502 from discrete TTL, so just eight bits, and even that took four Eurocards (and several months of simulation beforehand).
Now if only one of the chip makers had got around to doing a 74HC ALU chip...
Well, obviously, if amazon.com is good, amazon.amazon is twice as good...
and decided to try the same with books.
Curiously, I don't stream books the same way I don't stream music: if I have an ebook it's either been scanned by me from a copy I own, or it's a public domain book from Gutenberg or similar, or it's a naughty scan of a book I own but have not personally scanned. Note that I have discussed this with published authors and they are quite happy for this approach, though they would of course prefer that free copies are not generally available (I don't publish the books I scan).
is the Oatmeal's... http://theoatmeal.com/blog/jibbers_crabst
Watch the signing translator.
CDs locally ripped for me, every time. I don't even consider buying streamed music. That said, my life doesn't revolve around music; you could probably put my entire collection in a quarter terabyte.
Which is not to say that for others it may be something that works, but it's not for me.
More pepperoni, Sarge?
Followed one around the Mercedes test track at Brooklands a couple of months ago; they do make a nice noise from outside.
It's possible that the bright spots on Ceres are, in fact, the Clanger's Hobnob mines. Which is good news for planetary travelling, if true.
Could you not perhaps of borrowed มาลัย (which means Garland of Flowers in Thai) from Steve Bong?
I'm sure she'd have loved the change of pace.
Woo. And likewise, Hoo!
Oh noes, I emptied the interwebs!
Nine on my front page; everything else is Google's base install (as indeed are half of the front page).
I think you've had enough beans, boys!
What was the stuff that went bang made of?
" that exact 1,000,000 to one chance "
To be fair, they do pop up nine times out of ten.
But that's the good thing about Open Source - he has the choice...
Now if it were Clippy:
"I see you're trying to die. Would you like to be hit by a bus, eat a poisoned apple..."
it should have a little concertina fabric roof, like a 1960s Dormobile...
Kate can of course be installed on a Cinnamon system, but Geany does everything for me that Kate used to and saves half a gig of download (Kate wants an awful lot of the KDE infrastructure).
So teeneagers have as *many* as forty-four discrete communications symbols? Who'd have thought it?
It certainly seems so - none of these laptops bar the Tosh offer anything better than 768 vertical pixels? Why is *anything* at any price range offering less than HD in this day and age?
And I agree with Stuart - these are not 'budget' devices. Budget is Chromebook prices - two to three hundred quid.
that recently pushed for new legislation to allow its security services to slurp data wholesale?
Pinging Philae - do us all a favour and blink your nav lights, if you'd be so kind?
@Mark - I thought it was happily transmitting until its batteries gave up? And is expected to wake up again, once it sees a bit more light? That sounds like a walk-away landing.
@Bri - you're right, it probably wasn't on anything directly visible - but my point is that information like that should have been locked as tightly, and as accessibly, as if it were individual paper copies in a filing cabinet.
Access should have been restricted to a small set of people able to access *one file at a time* and ideally physically separated - airgapped - from generic access; that is, access permissions are physical, not electronic. This is not the sort of information for which there is *ever* a need for one person to see all of it, and a huge risk - as demonstrated - if they do. But some genius has been sold the idea that it would be much easier to deal with if it were all in one virtual database...
Which is not to say that it is only the USA government that can commit such idiocies, nor even that a one-file-at-a-time access mechanism would necessarily stop people trying, and perhaps succeeding in, gaining access illicitly - it's such a juicy target. It's not the only one - think of insurance companies, health agencies, tax agencies, benefit systems, banks... they're all in the same boat and if they're not thinking about this now, no matter how good they think their systems are, then they should be.
When hole is deep enough, stop digging...
What imbecile placed this data on an external-facing network?
As I recall, there was something of a science handwave in the final chapter, regarding matching orbits... looking forward to the film, though.
@Zog... no problem, I cook my rice in the microwave.
It's MBA syndrome.
MBA qualifications seem to emphasise the mistaken theory that if you know the numbers, you understand them; hence, SLAs and checkpoints and monitoring and measurement with absolutely no idea what the results mean.
