oh, less than 12 I'd guess.
Is it just the physical vibrations? I was also wondering if there could be ionisation in the rocket exhaust that could mess up radio signals?
That's a little bit harsh on the "sub-orbital lob" companies. Yes, a lot of the money will be from tourists but there are (or were - they have been a bit quiet lately!) a few companies (including VG) who were planning science-only jaunts. Apparently there is a surprising amount of zero-g science you can get done in a few minutes. Even though the time is short, for the same money that you would spend on launch to ISS, or whatever, you can get a _lot_ of 6 minute sessions and you can sit right next to your experiment so the apparatus can be a lot simpler.
Actually on fire? Or really, _really_ "toasty"?
Well, this project isn't rocket science and they've done it before:
"Manufactured, shipped, installed and readied for operation in roughly three months ..."
I think he (and his company) also pay rather a lot of tax in the UK too according to this report in the Indy (albeit a few years old): http://www.independent.co.uk/news/uk/home-news/the-billionaires-who-do-pay-their-bills-including-james-dyson-and-jk-rowling-7873607.html
You might also like John Scalzi (sci fi author) performing a skit with WW on that very subject:
It's from his "Redshirts" book promotion tour (the book loosely being a Trek parody) and, if I recall correctly, WW was reading his part live so didn't know where it was going ...
You should also hunt down the episode of "The Nerdist" podcast where they interview Patrick Stewart and he ends up doing the opening intro and various of Picard's stock phrases in a French accent. He also alleges that there is a tape somewhere in the vaults of Paramount where they did if for real at the time before deciding that it really wasn't going to work...
Pretty sure bitcoins can only be divided down to a "satoshi". Even if they extend the protocol to allow finer division (isn't protocol extension really tricky though? Didn't a previous attempt cause fairly major problems?) then I'm still fairly confident that they can't be "...subdivided to infinity". 'cos, you know, "maths" and "precision" and "finite number of bits to represent your currency units", etc., etc.
Hmm, quick bit of <search-engine-of-choice>ing suggests I'm wrong. Still, I think the "don't be a dick" philosophy is still good and you can surely enjoy the funny story?
So, this may not at all be correct but, I was under the impression that "paying for stuff in a shop" is different from "settling a debt".
When you stand at the till and they say "that'll be £11.63 please" then there are limits on what they are required to accept (which, as noted in comments above, are actually surprisingly small so often bigger shops will be more lenient) so you can't give them 1163 pennies and then shout "you're discriminating against me" or whatever if they refuse. This isn't "settling a debt" because you don't owe anything because they haven't given you the goods yet.
But in a restaurant, for example, you are "settling a debt" because at the end of the meal they have given you the goods and so you do now owe them recompense for that. I and thought, perhaps wrongly, that there was a different set of rules about what they were required to accept in payment of that debt. i.e. that they can't refuse to accept because you want to pay a £5.10 bill with 51x10p, for example, because it is actual money of the correct amount and you are legitimately attempting to settle the debt.
Of course all of this is covered by the general observation that life would be so much easier if everyone on both sides of these transactions just resolved to "not be a dick about things".
Which reminds me of the time I donated several years (and Kgs) collection of coppers to the work charity collection and said "You do have one of those coin counting machines don't you?" to which the response was "Yes. But's it's broken. But that's OK because we've got an intern!".
I think the point is that the "implementation" of their UTC functions just doesn't know about leap seconds so all you can do is externally set it back by a second at some point. i.e. the now() function can't ever report "23:59:58", "23:59:59", "23:59:60", "00:00:00", which is what it should do in a leap second. So the only option that they have is to "manually" knock back the time counter so you repeat a second as reported by the now() function. Having done that there is a risk that if you make two requests less than an actual second apart and the knock back occurs between the two, then you will get a negative value.
Hence Google's approach of just smearing the second out over a day or so by making multiple tiny adjustments such that you can guarantee that the smallest interval between now() requests will always still result in a positive number.
As usual, "Yes, Minister" got there first with the "would you support compulsory military service" questionnaire episode. Just got to find a link...
Ah, here we go: http://www.imdb.com/title/tt0086831/quotes
Didn't Charlie Brooker already do this in one of his "Black Mirror" episodes?
Running the fumes through the current filters produces ozone but using a high voltage spark won't? I thought high voltage spark was the very definition of how to produce ozone!
... I do recall back in the 90's being asked to install Windows 95 Japanese (*) on a laptop. It took me several goes to get it right (I think I had to install regular 95 first then install the Japanese version on top) so I had to ask the user to draw out all the kanji characters for the install wizard questions/answers.
(*) not just a "language pack add on" kind of thing, but a complete "everything is translated" version where the only English text was for trademarks/names/etc.
@esme - well official UK government policy is that our space programme is strictly an unmanned one. So we're just not in that race at all (rightly or wrongly - discuss!)
My reading of the article was that the inspector from the insurance company would be wearing the kit. He then just wanders around and, if he's been there before, just need to "look" at everything necessary. Possibly taking a few close-ups of fire-extinguishers, etc. to see serial numbers or whatever. Then, if it all works correctly, doesn't then need to spend hours/days going through his notes, working out where each photo was taken, cross checking every serial number with a test certificate, etc.
I saw this done in a documentary once: https://www.youtube.com/watch?v=0PxTAn4g20U
...given the recent announcement from Tesla about their truck plans, their undeniable speed of getting stuff actually on the road (notwithstanding their tendency to miss their overly ambitious targets) and the fact that they already have more real-world "autopilot" experience than anyone else - doesn't this mean that the first issue Volvo/Uber/Ford will face when they eventually hit the road is trying to merge into a continuous stream of TeslaTrucks ?
"It had to be seen to be Bee-lieved" !?
Bizarrely, I've done exactly the same in almost the same place. My pigeon swooped out the trees from the side and hit right in front of my face on the windscreen - it was loud and I totally flinched! But was quite proud of myself that I didn't swerve or do anything disastrous. The cloud of feathers was impressive ...
It's almost like he heard you ....

Does anyone know how to run a youtube video through some kind of de-shaking post processing? The rocket should be a nice stable point of reference...
@TRT - yes, that's when the article was from. They were doing authorised SPADs but discovered that, at low speeds, the automatic brakes were not triggered (because of the string/rope thing). Cue much tabloid hysteria about the tube trains failing because of the wrong sort of string...
Not sure if this is relevant but I recall an article from a few years ago that actually explained that many SPADs are when there has been some other signalling fault and the line controller authorises the driver to proceed across a red light over the radio. This still triggers the emergency brakes and is still recorded as a SPAD but is actually part of a defined procedure to avoid shutting the line down for every single little failure (i.e. not dangerous and not some driver just piling through a red light at 30mph because he wasn't looking). You know if you've been on a train that's done this because you'll crawl slowly out the station, suddenly stop, pause for a few seconds and then accelerate off as normal.
Allegedly there was a similar problem in the legal system with juries having watched too much CSI and asking why they couldn't have the grainy CCTV footage "enhanced", etc.
Have to admit my first thought on seeing the picture was that it was a Burt Rutan / Scaled Composites design (the people doing the Virgin Galactic craft, amongst other things) and that it was interesting that Airbus would be working with them. But turns out it's not. I guess small round windows is the only feasible choice so they all end up looking a bit similar?
"Some people will game the system of course by betting that the cost of them processing your dispute will be more than the fine is worth"
Arguably the council has already done this to you with the discount offer: "you owe us X for this alleged infringement but if you just pay up quietly within 21 days we will generously reduce it to X/2"
in some situations it is deemed safer to remain on the plane. Most extreme example of this being Qantas 32 (the A380 that lost an engine eplosively). I think the passengers sat on the plane for 3 hours whilst one of the other engines was put out. Obviously they were ready to evacuate the whole time but the pilot's view was that the outside contained a burning engine, hot brakes and a major fuel leak, and until that situation changed, inside was safer.
well, given that the contents of that cable could be at around 9kV I'm guessing that a number of paper-work inducing events will ensue...
But, I agree, this new "FCC Outage Report" will probably be the least of them.
well, hence the name _Ordnance_ Survey. Meaning either artillery or military planning/logistics.
I have no particular objection to a company saying to its workforce "this is what we believe the consequences of the two outcomes will be both for the company itself and you as as member of staff" - and then backing it up with some actual facts, actual reasoned arguments and clarification of which bits were opinion, company policy, etc. (*)
Of course I'd like the same from the wider debate too, so clearly I'm an eternal optimist due to live forever in a state of disappointment.
Well, quite. And also, if my drone could use wifi, 4g, 3g, etc. could it really block all those? Or some sort of custom telemetry on some random frequency? If I'm planning something nefarious with a drone then I'm probably not going to be too scared of OFCOM turning up to complain weakly at the unlicensed spectrum use ...
Actually I'm not sure that a "The Martian" style Hab material needs to be quite as tough. Pressure differentials about the same but even Mars' thin atmosphere is enough to stop the kind of micrometeorites and so forth that the ISS has to worry about...
i was watching the first attempt on NASA TV and he was being told to inflate it in one second bursts. It did seem to me that his definition of "one second" was somewhat quick and evidently mission control thought so too because the fourth or fifth "go" command contained the addendum " ... and make it a generous second".
This is yet another good step forward in space exploration and space technology development. But I can't help but feel that the actual thing looks a bit, well, scruffy compared to the various CGI/artist's impressions that were shown around before hand...
Well, it's not just about the cost of the power. It's also about the cost of the infrastructure necessary to deliver that power such that it can be consumed at any point along the route. Point of Hyperloop being that (a) less power is needed, and (b) it only needs to be delivered at a few key points on the route.
Well, according to this ( https://en.wikipedia.org/wiki/TGV_world_speed_record#Preparation_of_the_train_for_Operation_TGV_150 ) - about the current rail based speed record - you need a mechanical power output measured in 10's of MW which suggest the total of the various drags are considerable.
Hmm, don't agree with the use of FLA for "four letter acronym". You should use ETLA meaning "extended three letter acronym", that's much more IT appropriate...
yeah - I don't get that either. Given that "catching the rocket engines with a helicopter" is actually the plan of ULA for their Vulcan project...
So I guess for most people (including the more literate IT types reading here!) we are realistically already at the level where we have to take "secure/unbreakable encryption" claims on trust (because the maths is hard) but once "quantum stuff" starts getting used in real world situations it's going to get worse, right? The number of people who could legitimately claim to genuinely and fully understand how it works is going to go down by an order of magnitude (if not two or three!). 'Cos, you know, this quantum stuff is spooky ...
I was (very slightly) involved in the development of the Sea-Me-We-2 cable and I'm pleased to see they've continued the naming convention so we can continue to all giggle like 8 year olds just like we did 20 years ago ...
which also reveals a further TBD SpaceX launch in April...
"US Congresswoman Jackie Speier (D-SF) introduced a bill to prohibit the anonymous sale of pre-paid mobile phones in America"
Is it just me interpreting that as "OMG! Phones iz more dangerous than gunz!" ?
... not just PC's either. Once helped a friend gut a house he'd just bought (partly because of the hideous 60's décor and partly because the previous occupants were chain smokers). As we took down the lovely 60's polystyrene ceiling tiles you could crack them apart and see how far the yellow had soaked into the tile...
Based on in interview with him in a documentary I saw (that was actually more about Tim Peake) it appears that he does have a pretty good sense of humour but that it is very, very, ... very ... dry indeed. Whether that is representative of Russians in general or Cosmonauts in particular, I couldn't say.
There was a recent satellite launch on some similar flavour of converted ICBM (perhaps this one: http://www.theregister.co.uk/2016/02/17/sentinel_launch/ ) where it looks like, even though above ground, there is still some kind of tube that the rocket launches from.
I'm sure there's a technical reason (something to do with the rocket engine expecting a certain back pressure from an underground launch tube?) but it's also amusing to just consider that the rockets get nervous in the open air so they're given a little tube to hide in until it's time to go...
And presumably we'll find out shortly if Musk really does have any "volcano lair" tendencies as, in this situation, surely the temptation to use one's fortune to hunt down the boat's skipper and do something amusingly unpleasant to them must be very, very tempting ....
