I dunno what the 02 is either, but IMHO the 15 is the length of the following data within the manufacturer data field. Presumably 02 is Apple's code for "ibeacon id".
The C5 tx power is a signed 8-bit number, being -59 (decimal) dBm@1m.
"some observers are surprised that a country with such visible problems with poverty would spend its dosh on sending a probe to Mars. ®"
As usual, like people who complain about research in this country when they need a new bus shelter or the park has litter, doing the division sum shows that not doing the research would make available 1/10 of one meal per needy person, or 0.001 bus-shelters per parish, or similar. No of course I don't have the figures, but that's how it always is when you do get them :-)
Agree we should stop aid to India tho' - or be honest and admit it's a bribe for trade and good relations.
Love my Lobster Card
Exactly, the Oyster card is brilliant and makes getting about in London a pleasure not a fsckin nightmare like it used to be. And it's brilliant because it has limits on what it can spend every day, and so on. Why change anything?
Lots of companies seem to think this sort of thing is a good idea
For example, I've seen this recently pushed out: http://www.shopone.mobi/ (it's a website out there on the internet far as I know; so it can't be a sekrit, can it?) which describes other ideas in the same area.
I'm not pimping it, just offering another perspective and more info for folks... I too remain unconvinced that people will ever use the app in question, but AIUI the main idea is that it replaces your loyalty card and the paper vouchers you get with it. And indeed it may deliver extra vouchers/offers dynamically as you loiter, depending on where you loiter.
I just looked at the show's site. But at least it's windows 8 compatible :-)
They should be suing the UK Premier League for selling them something which doesn't exist: exclusivity. Well, doesn't exist in practice, only in the made-up legal things they invented and paid for resp. Can I sell you a legal right to fly like an angel? Sure. Sign here. Can't actually fly? Sue, um, Isaac Newton? Not me, oh no.
Last time this happened it was Sky here and the footy vs a pub who legally bought a European feed.
New screensaver image
I'm having that for my screensaver.... at work only, of course.
That way of controlling buoyancy is exactly what submarines do: suck in and store compressed the lighter-than-outside substance (air resp. helium) and let in the outside neutral substance (water resp. air).
With gasses you can use flexible bags for the buoyant part (instead of open-at-the-bottom tanks) and inflexible bags for the compressed storage (instead of high pressure cylinders). Density of He is 4, density of air is about 30 (molecular mass of N2 + some O2) so you only need squeeze the He to about 8 bar and it's no longer at all buoyant.
Fair enough, subs discard the air when they dive, and use air they stored compressed earlier when they blow tanks; and it vents as it expands as they surface and pressure drops, but.... it's the storage that they have in common.
And yes, it is Thunderbird 2, hurrah!
This is absolutely marvellous. That man in the hat made me write this.

Last ADFS bug...
I remember an all-nighter getting the last (hah!) bugs out of ADFS for the Electron. *COMPACT would sometimes corrupt the disc. Like on the Beeb, *COMPACT uses the screen RAM as working buffer by default - you get to watch your data flashing by as the disc is defragmented.
This works fine on the Beeb where the screen RAM is just memory, and the cursor is a hardware sprite.
But on the Electron, to save having that hardware, the cursor is written into the screen RAM using software in timed interrupts.... simple fix: turn off the cursor during *COMPACT. But the time it took to work out WTF was going on... you had to be there.
But at least we found it, so it wasn't me personally that cancelled Xmas.
Re: Fiduciary duty
Exactly. There's no point in them admitting that they take pains to minimise the tax they pay because they are already required *by law* to do exactly that for the benefit of shareholders (for all publicly traded companies).
It's just a no-op, no different from admitting the vile crime of attempting to maximise their profits (or market share, or whatever the strategic goal of the moment is).
I recommend "The State We're In" by Will Hutton for analysis of why UK companies are in an unusually difficult situation wrt attracting investment, BTW: it's because the banks are legally obliged to maximise profit, rather than "helping local businesses".
Government wishes and company law are indeed in contradiction here, unfortunately.
Langford Fractal Basilisk!
Excellent, the Langford Fractal Basilisk for teh win! Also used in "The Cassini Division"....
It's not just biodiesel, common diesel can grow the slime/mould/bug at an interface with water. As there's often condensation in fuel tanks, that's where it grows. But that only matters if you stir it up, so it blocks filters (before blocking the injectors).
Does the biodiesel one thrive throughout the fuel, or is there water dissolved in the fuel in biodiesel? That would happen if there are any emulsifiers (eg. mustard in salad dressing, detergents) present?
Parallels with the misidentification of not-the Boston bomber?
...might be a cause for concern. But indeed, you would think a sharp talking to by the FBI with the logo jackets and shades and everything would do the trick. So yes, fear conspiracy by the local incompetent biased law-enforcement.
Risc PC Podules
IIRC it was Mike Muller who coined Podule for the expansion cards on the early ARM-based development machines. That would make it 1985 or 6, I think. Certainly it was after Rowan Atkinson's sketch at the time.
Just: love the extension to the ISO 7-layer model. For years in pub talk, we have used the extensions "Layer 8 - Political" and "Layer 9 - Financial" to explain otherwise incomprehensible phenomena, I mean when less-capable implementations win, when laws intended to do one thing rather outlaw everything else, and so on. Government and big business madness in general.....
has a nice aside...
Isn't that RedHat's business model?
Paid enterprise level support is exactly what RedHat does.
What's happening here? Do businesses say "they want us to pay how much for free software?", missing the point that they want you to pay that much for professional support with SLAs and all that sort of thing.
Or is this about the bits they don't cover - OpenOffice and all that?
Does this need a special transmitter?
The article doesn't make clear whether you need to build a special peripheral transmitter for your phone to be able to send the bogus messages. That's quite important don't we think? Looks like you do, from the (truly groovy) presentation - not clear if the software-controlled radios in your WiFi/BlueTooth/FM chip in the phone can be hacked to transmit the trick packets.
That there are code-injection flaws and no authentication for all this stuff is of course unsurprising, sadly.
Same's true of AIS whereby ships report their position, speed, cargo, size &c &c to ground stations. I don't think the coastguard (analog of ATC functions) can automagically redirect a ship, but fake AIS transmissions suggesting unauthorised tankers speeding up the Thames could be a cover for a more serious attack somehow, as well as just disruptive in itself.
Is the movie intended to be silent?
I hate questions like that...
...precisely because they never state whether each pick is replaced before the next one. But whatever the quizmaster was thinking is "right" even though a crucial fact was kept sekrit.
...the pager. How very motorola. How sad.
Still, the things people are working on for your phone, yes you, the customer, are much sillier...
Double space blanket?
Have you space for multiple layers of space blanket and heatshrink?
Can you crumple up the space blanket(s) so it's more likely to have small airspaces too? Assuming the heatshrink is strong enough to contain the overpressure air if it's completely trapped - it certainly looks strong enough...
Naturally the hospital prosthetics department will have expertise in making such things; taking a mould, making a cast and all that. I only mention it 'cos you'd think it'd be obvious to anyone putting such a system in a hospital, duh....
Yeah, but the main thing about Tandem/HP NonStop systems is every CPU is duplicated, all memory is duplicated, and for every operation if the two results don't match the (dual)CPU in question STOPS. It's very keen on stopping; it's only a huge mound of failover software and redundant power and duplication that makes a *system* very keen on continuing; individual parts stop quite readily.
Of course, the intended market is OLTP, so the goal is to make sure that the decrement to your bank balance is the right answer; if two paired hardware CPUs and their memory give different answers, that pair of CPUs stops and a whole 'nother hardware set attempts the same transaction.
Baseband code is old, but...
...that's mainly because if you change it at all, you have re-do all the certification.
So they're very very reluctant to change anything. At all. Ever.
Required to be neutral...
Naturally civil servants are required to politically neutral in what they do in the course of their job. That's totally reasonable and sane. In the same way all employees are required to drink the company kool-aid and do what the boss says. But outside of work.... you should be able to have whatever opinions you like, so long as they don't actually influence the execution of your job?
I can see that there's a problem if it's likely that a very senior civil servant has an opinion about a political issue that must be based on inside knowledge; in that case they mustn't publicly comment, that's totally reasonable. But some droid from the council? Nah.
The Beeb article said it tool a *lot* of training....
says: "[It] takes about 45 days of training an hour a day," said Prof Nicolelis.
"There is a moment in time when... it clicks. Suddenly the [decoder] animal realises: 'Oops! The solution is in my head. It's coming to me' and he gets it right."
...so who knows what kind of stimulus the decoder is experiencing; the smell of almonds? Nostalgia?
Re: Open source would be dangerous
Ah, but open source makes it safe because the management cover-up over the exposed exhaust pipe would not be possible, exactly because everyone would know about it. No security through obscurity with open source!
Lead seal, I guess; like on your utility meter.
Article typo - 12-18 *inches*
"chunk of foam [...] 21-27in long and 12-18ft wide" ITYM 12-18 inches wide; "suitcase sized" is a common description.
That aside, good article, I wept too at the time, because of what it meant for spaceflight. ;-(
Spooooooky. The average temperature of the whole universe is (to 3 S.F..) exactly one percent of the freezing point of water. More proof that we're in a big simulation with a lazy sysadmin? I'll get me tinfoil hat....
OK, you(r family member) tested often the "pass" case of the fingerprint scanner, and got few false negatives.
But how often did anyone test the "fail" case?
If I've misunderstood and (for example) it logs in either you or dad or sis or uncle depending on fingerprint, then that's great and I'm impressed. But if it's always the same user, who owns the laptop, who is supposed to pass the login test, then it's not a test of security.
Everyone tried to copy it
Certainly "troubled Cambridge micro-maker" Acorn tried in the early '80s. The first ARM powered machine was supposed to be Lisa-like, but the researchers in the USA treated it like ongoing research rather than a product to be finished (obviously my bit was finished in time :-> ), that it more-or-less caused the "troubled" epithet and the development of Arthur and RISCOS in a hurry and instead.
Cell ID locations
So, er, why doesn't this happen more often? All cellphone positioning systems, if they can't do a trilateration/OTD/timing/E911 type position and fall back to a CellID position, will be positioned at one common location for the cell they were most recently using, the so-called "centroid" of the cell tower transmitter's coverage area (most cell towers have 3 or 4 transmitters pointing away from the tower, these have distinct IDs, so the centroid is not right at the tower).
Might it be that this particular cell is faulty or unreliable at making the data connection or timing observations that are needed for the more accurate methods? So anyone on that cell always get a crappy CellID position in that poor dude's house? This, they should investigate and fix.
You can always record the Special Information Tone for Intercept as the opening stanza of your comedic answering machine message... many automatic diallers will then flag your number as disconnected.
(Yes, the story is duplicated)
Um, so they mean that silent packets are 70 bytes of control/timing/keep-alive data, and packets-with-content are 130 bytes, being that same metadata plus 60 bytes of audio data. So a naughty intermediary can substitute long packets for short silent ones, with Steganographic almost-silence in the 60 byte payload.
The listener won't notice. The sekrit receiver software might even undo the change at the far end. The real point is that it gets through firewalls and filters and snoops just like the legit skype data does, surely?
Does that make sense? (No, can't be arsed to go read.....)
If we have a voting 1471-type report system, companies who have a genuine business relationship will soon learn not to use the same number for their legit calls as they do for spamming.
And other organisations will learn to present *something* valid eg. the global NHS helpline number, or bank contact number, or supermarket helpdesk, or... rather than anonymous if they want to get through.
Re: Fine BT for calls
1471: "to call back, press 3; if the previous call was a nuisance call, press 9"
together with a simple voting system, like "click to label this email as spam".
You're so right about charities; I always say to friends "here's a tenner, you're welcome" - no way am I giving my email address to a charity; they used to be the worst offenders for unaddressed junk (dead-tree) mail.
But for real places that were one-offs, can you go into your account and change the email address? I know it takes time, but I do that occasionally - for those places that have no "close account completely" button. Actually, I change the email address first, then close the account - so that if they still want to email, they can't.
....and let's not forget Lt.Ellis played by the lovely Gabrielle Drake.
Re: So, presumably
...especially if the decoy also attracts a mate somehow; either by direct "ooo there's a big strong mate" means, or by sexual selection, which as we know causes runaways in all kinds of arbitrary directions, if the *preference* as well as the attribute is heritable.
I think it's both: if the speed of sound/signal in the spring were infinite, you would still see the bottom of the suspended spring remain apparently still for a bit, but the coils would collapse absolutely uniformly. We don't see that.
The finite speed of (different kinds of) signal in the spring means the coils near the bottom don't collapse much at all until the wavefront of "going slack" approaches. But twist in the coil can get there much earlier because its signal speed is greater being through the stiff solid not via the spring property.
It's amusing but obvious that the top of the spring initially accelerates way harder than gravity since it's under tension <=> holding up the weight of the whole spring. That acceleration is because the tension is still there; you can view that as the weight still being there even though the whole is in freefall, because the rest of the spring doesn't yet know it's in freefall. Actually it's due to the mass/intertia of the spring which makes it unable to instantly collapse once the tension is removed, which itself is exactly what causes the speed of a signal to be finite.
Like a fortune cookie...
...all these terms work best followed by the words "in bed".
Re: Tiny correction
But isn't the density difference due to one has salt in it, the other doesn't, and salt in solution doesn't add anything to the space taken up. So when fresh and salt mix, it all cancels out. Even if the fresh was originally added as ice?
Could be there is a small increase in volume of liquid as you add more salt, but it's nothing like as large as proportional to the mass of salt because the dissolved salt "fits in the gaps" somehow. That's what ISTR as the point of an experiment when ah were a lad.
Does this mean it's Windoze only?
Re: Freeview radio - whats the point?
...and there are yet more radio stations again on the internet.
I prefer Polish ones, there's a set of genre-oriented stations with no talk and very very occasional adverts. But because they're in Polish, I can't understand a word so they don't intrude on my train of thought. (yes, I'm one of those people who hate it when a radio person says anything more than "That was Band B with track T, next group G with song S...")
