Re: Hydraulic accumulators
Yes, aware of the hydro schemes, I was wondering really how small they could get and still be useful. The answer is not very.
And thanks for the hydraulic accumulator stuff- IIRC this is what William Armstrong (of Cragside and hydroelectricity invented - nice link up there)- that's a good biography for those interested in that sort of thing.
Some while back I did wonder whether lifting up big weights is a useful energy storage mechanism - for example, use solar/wind while its there to lift a bloody great bit block of concrete, then use the potential energy during the night. But the weight you need to lift to get any decent storage is much too large to make it useful.
Ok at this small scale where you are powering low power LED's, not so good as a general purpose storage mechanism. Shame really.
Re: Not geostationary orbit - transfer orbit
The payload, had you bothered to check, is a 3.2 tonne communications satellite. Placed in a supersynchronous transfer orbit. Which I believe is the title of the next Muse album.
Re: How about a little perspective here?
Even faster - recent stuff from SpaceX says they are ramping to 24 F9s /year.
Won't take long, providing most of them work, to overtake most of the incumbents.
Looking forward to the the first 1st stage return - that's gonna be something...hope the onboard camera works....
Re: Mr. Musk's attitude
Actually, that's not strictly true. He spent a LOT of his own money up front to get the Falcons to a stage where they would be eligible for COTS. At that point, the government now has a contract which pays for SpaceX to supply the ISS. Which so far, it's been doing fine. It#'s a win win for all involved.
Of course, Musk admits he did get a lot of tech help from NASA without whom he wouldn't have got to this stage. On the shoulders of giants etc etc
Re: Especially with his track record...
Actually getting your facts straight before posting seems somewhat lacking in the trolls nowadays.
Nice try troll. But factually wrong.
Re: Another faulty valve? @ian 22
Oh, do you need valves that can cope with cryogenic oxygen? Weird plumbing you've got in your house.
Valves that can cope with the sort of stuff required in rockets are quite well engineered devices.
Re: Cheap version? @Ken
I know exaclty what he is talking about. But that is not a fair comparison, since the OP was about the price of the mathematica stuff only - no PC, no screen, no keyboard. But I guess if you had no kit AT ALL, then $150 or so for a complete system is still cheaper than the base price of mathmatica. If of course you already have a monitor or TV....
Re: "free box of tools" @Oh Homer
Not withstandaing you seem to be completely mental, you arguments make no sense whatsoever.
Here are people, giving you stuff for free. You don't need to use it, you don't need to become reliant on it. And you cannot stop complaining.
You seem to this the Raspi foundation has made questionable decision ? Like what? Every decisioon I can think of that they have made has been entirely pragmatic. They may not be the best way if you want OSS, but then, they have never claimed they are an OSS platform - just that they use OSS stuff. But, can you show me a completely OSS platform, that can be made for $25, that can do as much as the Raspi can? No you cannot - the decisions made have enabled the Raspi to become the very popular device it is. It may be news to you , but almost every device being used, in education as well as everywhere else, has propritary tech in it. WIthout proprietry tech, many products we use day to day probably wouldn't not exist. It really REALLY doesnt matter if an educational device has prop tech in it, as long as it does the job its intended to do at an acceptable price. Arging it doesnt make a good eduicational dev ice becuase it has some closed source components is a straw man, and easily disproven given the strides already being made.
As for the money the Raspi Foundation is pushing in to OSS, would you prefer it WASNT being spent - would you prefer it being spent on closed source effecots? Your comment on this is one of the most stupid shortsighted comments I've ever seen on here, and that's saying something.
Since you obviously feel so strongly about his, I think you should be starting your own charity, deisgning a fully OSS board, spend a $mill or so on software for it, and compete in the educational sector. Or do you think, just maybe, that that would not be possible?
Re: Mathematica on a Pi????
"But then that probably wouldn't satisfy Broadcom's Upton's predilection for proprietary technology."
Cockwomble. Everything you use has some sort of proprietary tech in it. So you single out a charity to vent your anger. Perhaps aiming it at more deserving companies might be appropriate? Or even better, just don't use anything with proprietary tech, don't get a Raspi (which has a fairly minimal amount of it compared with your Smartphone or TV for example), and please just stop whining. Richard Stallman is happy enough with the Raspi as it stands. Why not agree with your hero?
Re: Cheap version?
I've got a couple of Pi's if you are willing to pay that amount. They cost me $35ish, but I'm willing to let them go for $100.
Re: "free box of tools"
Tell you what... if you buy as Raspi which comes with this stuff installed and disagree with some aspect of it's licence, or closed sourciness, or similar, DON'T USE IT.
There, all your objections negated in three words.
As for SAGE, good but not as good as Mathematica. If you want it on a Raspi, install it. It's not in the repo, but I am sure you can download the source and build it yourself. Go on - make a contribution rather than whining about how all this free stuff you are getting isn't 'free' enough.
Grrrr. I'm as much a fan of OSS software as anyone, but you zealots do yourself no favours with this constant whining. Would you like to know how much money the Raspi foundation have pushed into the OSS community this year? On both Raspi specific stuff AND more general stuff applicable to OSS as whole? $1.5M. How much have you done?
Re: What a stupid idea
Well, tbh they've probably done both. And the 4k is really only for displaying on a separate monitor/TV using cable or Miracast or similar. Although I agree with you that 4K is pretty much pointless unless you have 50" or greater display at the usual viewing distance.
Re: Some context @Christian
Yes, there is, and yes, they are.
Re: @Robert Long 1 21:31 @James Hughes 1 10:12
""You can believe or not believe what you like."
Thanks. I was waiting for your permission."
Hmm, I wasn't giving permission, just stating a fact.
"And no, I really cannot be arsed spending time proving it to a cynical AC who really needs to think more before posting."
You should think about doing so. As I recall you've stated you're involved with the project; since you leap to defend it any time someone isn't squeeing about it (which is what I *am* cynical about - not the project,) you obviously want people to believe you but you're just not a reliable source. Not that anyone has answered the OP's question, of course."
On the other hand since I do all this for free (volunteer), why on earth should I do research on a subject for an lazy arse AC who cannot be bothered to look it up himself. All this stuff is freely available - just check the Raspi website.
At least I have a cause to defend, that I believe in and am willing to put my name to. Try it sometime.
Re: Money, money, money
In fact, they do get the sales figures from RS and Farnell, but there isn't much point in analysing every detail as long as sales are OK.
The Foundation get a fixed royalty on each sale, so there isn't much 'penny pinching' to do even if sales did drop off. The manufacturers are able to penny pinch by changing components etc to make the board cheaper to construct, but the Foundation royalty stays the same I believe.
Re: Some context @Christian
Very unlikely. The cost to develop an SoC even as capable as the one in the Raspi now is in the multiple 10 of millions, and would take years. These things are complicated with a capital F.
The ARM side is pretty easy (!), but to duplicate the media features - well, there are 1000's of man years of work in that GPU.
Re: @Robert Long 1 21:31
You can believe or not believe what you like. But there are people out there using lots of Pi's, in schools, and elsewhere. And no, I really cannot be arsed spending time proving it to a cynical AC who really needs to think more before posting.
I've found SSD to be more unreliable that disk. Anyone have MTBF comparison figures for decent SSD vs decent disk?
If you insist that we in the country are termed bumpkins, does that mean we have free reign to call those people who live in urban areas a bunch of c**ts?
Note to Journos. Not every one who lives in the country is a bumpkin (although I know a few) in much the same way that not everyone who lives in urban areas is a c**t.
Except BMW drivers. They are c**ts in the country as well.
Re: Had to be BMW @AC
Indication is not optional. Even in the circumstances you outline, it's easier for the cars around you to see what's going on if you indicate. Also, most of the roads/roundabouts around here, most of the road markings have worn off, so you have no idea which lane to be in anyway. BMW's tend to ignore lane markings anyway and just drive where they want.
Most BMW's I see, as well as old Vectras for some reason, seem to have the indicators disabled.
Re: Back in the real old days
I'm sure Gordon is quite capable of doing that, Mr Dropbear - he did write the BASIC used on this device after all...
On the other hand, he could just use the OpenVG command.
Re: Fruity Firm FAIL
That's what I don't understand - they are not going to win this battle. Ok, they may get a load of cash in settlement, but that's it. SS will work round the patents, Android will continue to dominate, and Apple become the sad also ran in the corner, dining out on past achievements and failing abysmally to innovate themselves back to the top.
Re: how precise is a piece of string?
Being desirable to you isn't really on their list, so I guess you'll be waiting some time. For the VAST majority or people it'll be fine.
If it wasn't so expensive It would be on my list to replace my 203k miles, 11 year old Honda Civic. (My other cars are a couple of Locosts, one race, one road - those for fun, electric for commuting)
Re: not so even handed
And I think you are a sanctimonious wanker for thinking that.
Wood - meet trees. Can you see the problem yet?
Re: Are you sure?
Er, what? Have you been visiting amanfrommars?
Raspberry PI's are already in schools. Not every school but more than a few.
Quite. Note to ElReg hacks - Guitar big, 6 or 12 strings, Ukulele small, 4 strings. This is NOT a reference to Father Ted. They really ARE different sizes.
Re: Seems everyone agrees.. @gav
You seem to have missed out the 'actor arrested for kiddi fiddling' plot.
And yet that electric car will piss all over your American V8 muscle car round a track....*
There's a lot of angst in the F1 watching community about new engines not sounding right. Its bollocks, as longs as they go round the track ridiculously quickly who gives a shit.
* YMMV. Depends on the cars.
All three Tesla fires were caused by accidents, there hasn't been one that just 'caught fire'. Unlike Ferraris.
The best of the Tesla's is the second one - where the car caught fire - after driving over a roundabout and crashing though a concrete wall. I'm not blaming the batteries for that one...
The other two are just hitting bloody great lumps of metal on the road - the recent one was unseen as a lorry swerved round it, the Tesla hit it. The driver is quoted as saying he things the Tesla saved him from a more serious injury he may have had in a normal car.
What interesting is that the Tesla do have intrusion penetration protection, and yet the impacts still went through. Given that even in rally cars which have very strong underprotection, people still get injured (Robert Kubica), so I wonder if its actually impossible (within weight limits) to make something impenetrable.
Re: Media Firestorm?
I think your opinion is wrong. Doesn't sound like deliberate company policy to me. Shuttleworth isn't stupid. He's knows doing this sort of thing is going to end in bad publicity. To paraphrase, don't put down to maliciousness what could be blamed on stupidity.
"After publication, Dr Ioannis Ieropoulos from the BRL got in touch to clarify: "The EcoBot line of work developed at BRL has always had the benevolent waste utilisation in mind, and so when these self-sustainable robots are being developed, the main target application is remote area access, where it would be lethal, impossible or undesirable for humans to go. This has been at the core of the research and any association with the science-fiction imaginative robots [to which] you refer would be inaccurate.""
Well, he would say that, wouldn't he! That's what they said about Skynet.....

Re: No programming required
I disagree (as a child of the BBC micro 80's). The work I had done prior to university made the first year a doddle (Pascal). Same with the A level CompSCi the previous year - did a year long course, got an A. All on the back of writing code on the BBC micro in my spare time.
Got a bit more complicated in 2nd year when C was introduced, but still graduated top 4. I firmly believe this was due to my experience of 'bedroom' programming.
But why do they bother? Jake has already proven is a load of bollocks, they just need to listen to him. Well, someone needs to listen to him...someone...please listen.....please....
Re: Ditch the aluminium @frank ly
Damn, came on to post that and you beat me to it.
Re: Upholder class
Not seen today's news then?
My thoughts precisely. I see no reason why they shouldn't add a little 'professionalism' to the development, and by that I don't mean to insult the obviously talented people who write much of the kernel code, but to say that in my job, as an alleged professional, I spend a lot of time fixing bugs in product, so it's fit for purpose. Kernel developers should understand it's part of being professional. You don't get to work on the good stuff all the time.
And while they are at it, can someone fit GIT so it's usable by humans without 2 years of training.
Re: Gimmicks not needed
Indeed the iPad was a game changer. But the game has now changed. Now the iPad is similarly specc'd to many cheaper devices, and tablets are a commodity product. Now, the iPad is not really distinguishable from any other tablet.
As for comments on getting work done, my £129 NookHD+ does everything I need, quickly and efficiently. It's never crashed and seems to update itself in the background without me noticing. I'd be hard pressed to say it was any worse or better than an iPad of whatever vintage.
As for 64bit, you may get a slight performance increase in the right circumstances. But do tablets really need it? (Notwithstanding that, end of next year nearly everything will be 64 bit anyway due to marketing pressures, not because of any major advantage in using it)
Re: @Pierre Castille - No Chance in Hell
I believe the pods are much closer together than 45 minutes, and I cannot see your argument that driving or planes will be as quick as this.
Go on then, solve the elevator problem. You can do that whilst other people work on the completely different problem of efficient earth borne transportation.
It's never an either or situation - the preferred argument of the uninformed. There are plenty of engineers (and probably money) around to do BOTH.
Depends on your definition of faster. Faster to run, slower to develop, slower to fix, slower to port to a new architecture.
At the negativity these things bring out. Real hostility to what is after all just a smartphone on a glasses frame. And EVERYONE commenting here, I expect, has a smartphone.
As for what Google are doing here - what's the problem? New iteration of a new product (just like every other company does) and Google are offering an upgrade (you know, like Apple do with iPhones, except they charge loads). Hardware changes so fast nowadays it's remotely surprising they have a new version out already.
Re: Bogosity @Pete
It's 2M actually (or very close).
If its easy for schools to drop SW on their PC's and use them for programming, they should do it, the Raspi is just an additional tool, intended more for the people at home than the schools themselves.
And if you think an A20 is so much better, and the boards so much better designed, well, try some benchmarks, and look at the sales figures and the community support behind them.
Right and wrong
Kris is right in his premise, that the Raspi is not by itself the saviour of British computing. But his arguments for that are aimed badly.
1) Yes, most household do have a computer. But they don't usually have one that available for enough time for development. Case in point - at home we have one PC shared between 4 people. That's simply not enough time for me to sit down and do dev work without someone else needing to use it. Also, PC's are not great for any sort of HW interaction.
2) The Pi is easy to tinker with. Yes, it is, considerable easier than a Windows PC. Arduino is also a good option here, but needs a separate PC for compilation - the Raspi can do everything on board. Or attach an Arduino board to the Raspi for the best of both worlds.
Note that the uUSB connector is not fragile - it's rated for many thousands of connections. Or you just turn off at the mains...I do both.
3) Linux is not easy. True. Easier than it was. But don't underestimate the knowledge absorption capabilities of the average 14 year old. If they learn Linux at that age there will be no stopping them.
4) Lots more bedroom programmers. Difficult one to assess. There may well be, but the arguments put forward are not related to the Raspi at all. Yes, there are many languages to choose from (but, TBH, just go with Python or C), and read up on the turorials from the MagPi or from the coursework being produced for the new curriculum.
5) Well, I think you are stating the obvious here. Of course, by itself the Raspi is not going to change to the world - it needs teaching material, good teachers, the right languages (easy - Scratch for the young ones, Python and C and perhaps Java for the older ones) - all those things. But then, so does any other teaching device.
But most importantly - teach the concepts and logical thought. And when only 5% of those you teach think this is great and show aptitude -' I'd like to do this for a living' - then you have a success.
