Re: £10K cap per household?
Not heard of a multiswitch? Standard equipment these days in blocks of flats to distribute sat signals. Some of them will even do two or 3 sats (9/13 input jobbies).
Wot, no Sheridan Smith?
Missed your first candidate call, otherwise I would have suggested her. Lot of no-hopers in that list though. You can immediately chuck out the ones with no Equity card. However, in the absence of Ms Smith, I think Rhys Ifans playing his Howard Marks character would be suitably counter-cultural.
Re: Interface (Verb)
Odd that the EJ200 is specific to the Eurofighter. Usually jet engines have a wider range of use cases. I would have expected some kind of common interface API to the engine management unit, with a specific set of control algorithms for the Eurofighter which can be reprogrammed for other kit. But then I'm a software & networking guy so I tend to think in those terms.
Re: Too many moving parts...
Didn't you know? It's actually Swiss farmers who are driving all this stuff. IPv6 wouldn't have happened without their reps on the IETF...
Fighter pilots already know this
Information Overload. I can see this becoming app-heavy so it takes all your concentration. Of course, if the app turns your car into an Autonomous Googlemobile, then you can quite happily play the latest incarnation of GTA:Sin City or whatever whilst travelling.
They did assume broadcast on LTE
Reading the paper, it looks like they did assume broadcast on LTE for broadcast-type networks, thus using some of the LTE bandwidth stolen from traditional TV for that. Even so, the numbers don't look good. A DTT network is now extremely well optimised for its purpose, so it's not too surprising that a network optimised for more general-purpose communication, including mostly single station to single station communication, would not compare favourably on spectrum utilisation.
Re: What? @Shasta McNasty
So now my toaster also has to have a LCD display, or a HAL-like voice to say "I'm sorry Dave, Corrie break in 5 seconds. I'll do your toast in 4 minutes and 15 seconds".
The Kid might have had his brain zapped by that Swiss finishing school, but even he would know that the US would only be accept a wooden rabbit.
Re: Enta outage
I've used a D-Link 300T modem in bridge mode successfully with Enta IPv6 to my own linux-based router. I've also successfully used a Draytek 120 in the same setup, though I'm back on the D-Link as the Draytek has become unreliable (either bad capacitors or a bad smps, probably).
Re: Earning their keep
One of our neighbours' dogs was savaged quite badly by a muntjac some years ago. They have become much more numerous in our part of the world (SE Suffolk) over the last couple of decades. I often see one crossing our garden at night on the CCTV.
No-one has suggested Lynx as a candidate for re-introduction, though I think they are more at home in hilly or mountainous areas, so Suffolk isn't exactly prime territory for them.
Uzbek, as in Afghan, Tajik, Kyrgyz, etc & not in Pakistani.
Re: Sorry, wrong.
Any respectable specification *should* have a conformance test suite. Googling finds me a UEFI Self Certification Test specification, so it looks like the spec writers did their job. However, we all know what 'Self Certification' means (think CE marks). Looks like the only test Samsung did, as you say, is whether Windows boots ok.
Average figures are pretty useless, except for politicians
I'm more interested in the distribution of speeds, i.e a nice little histogram rather than just one average. That would tell us a lot more about the state of connectivity in the UK. In an equitable world the slow tail would get upgraded before the fast end of the distribution gets even faster. But that ain't gonna happen any time soon:(
Re: Got both - dont care which is supposed to be best.
My (Tosh) laptop used to have a matte screen, until the wire broke off one of the flourescent tubes & I failed to repair it. The replacement, much to my chagrin, is shiny. It shows up fingerprints much more, quite apart from the greater reflectivity. I wonder what the incremental cost of putting antireflection coatings on sceens would be.
As for matte 'blurring' detail, my view is that, because the matteness is close to the emitting surface, then it doesn't really affect the sharpness, especially as the roughness scale is probably smaller than the size of the pixels.
I guess Plusnet would at least have considered using NAT64, except that most wireless routers don't support it, and probably don't even have a firmware upgrade to do so. NAT64 still has the NAT-specific drawbacks that v4 NAT has, but at least it would make the home network IPv6 by default. Perhaps as home wireless routers become capable of IPv6 they could start to run NAT64 in parallel.
Re: ofcom and bt has probably always known who and where from
Phone calls don't work like the Internet. An international call arriving into BT has a known endpoint on BT's switch, and they also know which overseas operator it came from (for charging) and some forwarded CLI, which could be anything. There is nothing to say it bears any relationship to the call originator, and it doesn't have to be accurate for the call to be successfully connected. So BT can connect the call in the UK and mark it 'International'. They may even trust the CLI in some cases and pass it on, but I've never seen that on my landline (not that we get many genuine international calls).
Having CLI on our phones, all 'International', 'Unavailable' and 'Witheld' calls are not answered & go to the answering machine. Almost without fail they hang up. It's a low hassle way of filtering the crap, though it would be good if there were a way of wasting their time without wasting mine.
Re: O2 boostbox doesn't work
That's the weak point. The support peope aren't really support at all. I had this exact problem. The young lady I spoke to at Voda was very pleasant but very soon ran into the limits of her competence & understanding. It was almost a case of "sorry, can't help. goodbye" until I said " if you can't help, who in your organisation will?". It got escalated to a manager, but even he wasn't happy in owning the problem, even though I could tell him exactly where the problem lay in his network. The support people ought to know much more about the detail of how the service actually works and be able to run connectivity checks.
I was invited onto Voda's trial some years ago, which was a real boon as we live in a hole. We've had a few ups & downs - when our previous ISP changed upstream provider, it all went dead and I had real problems persuading Voda that it was a missing entry in their network whitelist. It seems to go off from time to time, but less often these days. My wife also notices that it sometimes seems to die after a while in longer conversations - dunno if that's a femto issue or an issue with our broadband. The box we have is the original Sagem one. The new one looks to be a tad more convenient to connect but less easy to place for good coverage IMHO.
We only use it for voice & text - the home wifi takes care of Internet from our phones. Why would you want to run Internet over the tunnel, using up a monthly data allowance, when it's available directly on broadband?
A charging elephant has mass & velocity, so surely it's a unit of momentum. The force then depends on how quickly you can stop the charge: Ft = mv so as t gets smaller F gets bigger.
Re: Angling to get another Brit into a US Court?
HP hasn't been the business that Bill & Dave started for decades. The remnants of that is Agilent, which still has a respectable rep in the instruments business. It's all very sad - I remember reading HP Journal back in the day in our company library and being amazed & fascinated by the techniques & equipment described therein. I dunno why, but it seemed to be de rigeur to be a backpacker to work at HP. Virtually all the author bios seemed to feature backpacking as their leisure time activity. It became something of a joke at our place.
Too true. It ain't. A DNA database is a damn great directed graph (acyclic? - probably not) with the cross-matches as the links. So given enough identification within the database, any other entry can be identified by the relationships. The police already do this in their own DNA database to identify relatives of existing entrants.
Re: ""the underlying data from NOAA...."
My thought too, but I guess the ballooners have done this stuff before many times. I did notice on the map display a couple of others in the drink that day - one off Southend IIRC and one off Margate. Hope you've got enough in the kitty to refund the kit donors - that Iridium box must be worth a bob or two.
I hope you've got another intepid Playmonaut in training who hasn't just resigned...
I live in a village, with a cabinet about 100m away, and our county council is just finalising a deal with BT for rural broadband. I hope they do fibre up that cabinet, but I suspect the best we'll see is an upgrade from ADSL2 to ADSL2+. I'm also expecting it to come in late.
Don't think they are strowger switches - there is no rotary switch bank below the relay bank. The covers look like those on the pre-2000 type switches I saw in Manchester Central exchange back in 1969. No doubt another ex-GPO commentator can fill in more detail.
Re: Note that *accuracy* prized over speed
From the edges of the roof tiles it looks like it is a fish-eye pic, and in actuality the racks are in a line.
Re: Counterfeit Cards
The conditional access system, SECA, that OnDigital used was actually already broken on satellite systems when the service started. The info was fairly readily available if you knew where to look, and I used it as an example of how not to design a security system in an internal talk where I used to work.
Re: Get one at home?
"With the increasing litigation against 'suspected downloaders' it is a good way to get sued/prosecuted."
Don't be silly. I've had a Voda box for a few years now. It uses a IPSec ESP tunnel to backhaul the traffic, and I, as the owner, need to register other people's phones onto the box before they can use it. That shouldn't be too hard to argue issues of responsibility in court, if it ever got there, even with judges' notorious lack of tech awareness.
Nice idea, but it won't happen
Because it's end-to-end, just like TCP is, so it requires a large number of endpoints to change just because, probably, 1 link in the chain has high packet loss. What would be more useful is a network encoding protocol built into the wireless link layer protocol. I know it fits pretty naturally into TCP's windowed protocl, but that's not enough to swing it IMHO.
I built a decoder for this
When Ceefax first started, Wireless World published a design for a decoder & provided circuit boards. It was 2 boards full of TTL. I remember building this - must have been in 1975 or so, as it was before I moved house in 1976. The original lash-up connected it into the RGB drive circuits in the back of the TV - chassis connected directly to mains in those days! It was later put in a case with proper 75 ohm drivers etc. The page number was set up on thumbwheel switches - remotes were a thing of the future.
I'm well chuffed with Sure Signal (mostly)
I was phoned up by Voda some years ago & invited onto the trial - £100 and a free femtocell for filling out a couple of questionnaires. What's not to like? I grabbed at it with both hands and all my teeth, especially as we live in a hole.
Subsequent service has been mostly good - a few outages but not too long usually. Except when my ISP changed their upstream provider & the femtocell stopped working. I guessed the problem was Voda's whitelist for UK networks, but could I persuade Voda's SS helpdesk of that? It took several e-mails to an unhappy manager there getting him to own the problem for me, and a couple of weeks for him to get their networks people to sort it before I got service back.
Why am I not surprised?
UK and US have an 'Anglo-Saxon' (as the French would put it) tendency towards individualism rather than conformity, so it's not too surprising that there are more sceptics in the UK and US. This goes for all sorts of other issues too, right down to the popularity of conspiracy theories, particularly in the US. That's not to say that climate sceptics are all conspiracy theorists - I am definitely a counter example! - but the same kind of questioning mindset, and not taking things at face value does give rise to both groups.
Re: Not radical, at least nolt compared to what is actually being done
This guy definitely needs to be hit with the 'Be careful what you wish for' cluebat.
In any case the L1 Lagrange point already has sun observation satellites, which will be royally shafted by a dust cloud there.
Re: A shame, shameful prosecution
As was pointed out, this is a strict liability offence. There was little doubt he sent the text, so he's guilty, whatever his intent. I dunno if the CPS even have discretion in prosecuting strict liability offences. Sadly, the solution to this is only in the hands of our MPs in repealing the legislation, so don't hold your breath:(((
I wonder if the Apple one ticks? The other feature of SBB clocks is that the second hand takes about 59 seconds to do the sweep, then it stops, and the whole thing kicks off again with a pulse exactly on the minute. Has anyone been on a Swiss railway station in the early hours in March or October to see how they do the summer time adjustment?
I thought about buying a Swiss-style clock once but they are horrendously expensive for what you get.
Strictly speaking, Fish was correct. Hurricanes contain *lots* of rain - many cm in a few hours, as well as the high winds & thunderstorms. All we got in 87 was the high winds, apparently caused by a 'Sting Jet' (see Wikipedia).
I wonder how much they paid the whalesong brigade to come up with that? If those four squares were hanging in the Tate Modern (or Charles Saatchi's pad) they would be worth millions.
"If resources are limited, then expenditures on acts of petty virtue - that may make microscope changes, that have no impact on climate - should be put under the microscope to see if they make best use of social resources compared to adaptation"
Solid common sense. This is essentially what some so-called sceptics have been saying for years, including Nigel Lawson in his book, and AFAIR, Bjørn Lomborg. Sadly Gordon Brown, together with much of the HoC, completely failed to grasp this, and so we're stuck with the millstone of the Climate Change Act 2008.
Re: I'll be damned...
I *hope* you are being sarcastic. I've just looked at the membersip of the HoL Communications Committee. Not an engineer among them - it's a mixture of meeja types (Joan Bakewell, Melvyn Bragg), lawyers, and pensioned-off career politicians, plus a bishop...
Even given the cost of all the transmitters & the distribution infrastructure, and the imputed value of the spectrum, I reckon it's still much cheaper than a fibre/wire network for multicast to the necessary specification. I've got three TVs and a PVR that can record 2 channels simultaneously. That's potentially 5 different HD channels required simultaneously - say 60-70Mbit/sec with all the network overhead. And I'm sure I'm nowhere near what some households would require. And I live right out in the sticks with no prospect of getting anything better than ADSL2 (not even 2+) in the forseeable future.
A wire network is much more controllable by the State too...
Nice rant, but a tad misplaced IMHO. People do rave about breaking records, and sportspeople have individual goals, e.g. personal bests, that are very important to them, even though they may not be potential world record breakers. So the absolute measurement is important. But if you think about it, the time, distance, height, whatever is actually less important than the *ordering*. Sport is a competition, and the order is always supreme in a competition. As performance margins at the top in sports get narrower, it becomes more important to measure those small differences accurately. Hence the clever tech so admirably described.
Re: How long will we
@Cowherd: I get a distinct feeling of deja-vu reading this comment - seems to be recycled from a previous discussion on a related topic here.
For myself, Sizewell B is just up the coast from me, and I can't wait for them to get busy building Sizewell C. Also, as I understand it, future nucear power stations are going to be built on the site of existing closed Magnox & AGR stations, so it's not as if the locals aren't aware of nuclear power on their doorsteps. As far as I'm aware, the locals haven't turned up at nuclear stations in the past with pitchforks, burning brands and lynching ropes - It's deluded greenies who engage in that sort of behaviour.
I'm all for fracking too. Nuclear can potentially provide a large fraction of our demand, as it does in France, but the output of nuclear (at least current designs) can't easily be modulated, so gas stations (and Dinorwig) will provide that match to varying demand. Also, it'll take at least 10 years to get new nuclear online, even if someone can cut the Gordian knot of the planning process, so gas is the obvious interim fuel.
Dry and compressed thermite doesnt explode. It just gets very hot & produces molten iron. This is how they used to weld railway track, perhaps still do. Having said that, one of my teenage escapades was to mix a stoichiometric mixture of Al powder, & Ferric oxide, both readily available finely divided as pigments at the time, in a 1 gallon paint tin. However the mixture was very fluid, and I knew it needed to be compressed under vacuum but didn't have the kit to do that. So we stuck Mg ribbon in the top, lit it & retired immediately. The thermite caught, and the superheated air in the mixture blew the stuff into a fantastic fire fountain, followed by molten iron running over the ground (this was in a disused quarry). Sadly, today, I would be banged up as a terrorist for doing that:(
Funny you should say that
I read on one of the digital TV fora that there is a proposal to move TV from the 700+MHz band and use that for comms services as well. If anyone in government eventually thinks that's a good idea, then we'll have a complete nightmare of a band re-plan, even given that channels 31-39 are currently unused. And of course
we'll then have exactly the same problem at ch49 that we now have at ch60.
So what about masthead preamps?
A filter needs to go between the antenna & the preamp, and I don't think 60 quid is going to pay for the installer to set foot on the ladder, let alone re-plumb the coax up there. I'm hoping I'm far enough away from a LTE base station not to worry. It'll also be interesting to see what the performance of the offered filters is like - only 1MHz of guard band between the top of Ch60 & the bottom of LTE at 790MHz makes a practical filter more or less unrealisable:( And that doesn't even begin to address the issue of the allowed out-of-band LTE signals *in* Ch60 & below.

I think you'll find, if you look more carefully, that it's Elvis with a suntan.
Re: Nothing wrong with BASIC (line nos)
What's wrong with putting __FILE__ and __LINE__ in fprintf(stderr,...) statements, or equivalent in other languages? I'm glad I got into this stuff before BASIC became popular, by which time I had moved on from FORTRAN taught in a 1 semester course at uni in '69, to Coral 66, PL/1, Pascal and even played with BCPL. It's funny, though, how playing with lots of languages pays dividends. I found I could easily hack on the ancient FORTRAN code in the NEC2 electromagnetic modelling program, and more recently some amateur radio stuff where the author probably uses FORTRAN because he used it all his career.
I've seen some funny code in my time, but the one that takes the biscuit is some C code (no names, no pack drill) that, if possible, is even more convoluted than a BASIC program and no, it's not a submission to IOCCC . Virtually no indentation (though that can be fixed with astyle), and too many gotos without reason. Perhaps the guy started with BASIC & never really escaped the mindset.
I do confess, however, that I've never really got to grips with functional languages and that programming style.
I dunno what his tech credentials are, but reporters often come across as Joe Thicko in the questions, because they have to ask the questions Joe Thicko won't have thought of 'cos he's thick, but still would like to know the answer, if someone asks it for him.
As for HTML, no it's not a programming language, and IMHO, HTML is crap to use for someone who is an occasional marker-upper. It really is the markup equivalent of assembler. Better to use some kind of web page development app that hides the ugly syntax.
>>> print "Hello World"
>>> def hello():
... print "Hello World 2"
Hello World 2
Easy as Basic, no gotos, intro to classes & objects if you want to go that far. Its only drawback, if you want to see it as such, is the indentation as block structure, but since most programmers use indentation to clarify structure anyway, this is hardly a killer.
