I shouldn't have said "Smartphone".
...as I was thinking of things like the 42U rack unit with hundreds of ARMs in it that was featured here once.
Although a literal cluster made from Smartphone PCBs would be amusing, practical or not. I'm just thinking along the lines that something like web serving can potentially be quite massively parallelised. Given that some SoC or SoB arrangements can end up taking just a couple of watts each or less, that's matching or beating the performance per thread of the T3-2 machine, even assuming the boards are only capable of maintaining one session each. Then you can dial the thing right down so only one board is operational, so 2W (potentially) to keep an entire cluster ticking over in an idle state. Good, no?
Okay, not suitable for all loads, but I can see why the drive toward tiny servers with lots of cores is happening.
Re: wild rotation?
I'm kind of with others in wondering why the big solid backplate too. The rocket is probably going to provide a hell of a thump to that plate when it goes off, and I can't see how it'll do anything but push the whole platform back, especially if there's a halfway-reasonable rocket engine providing the punch.
Now you could possibly re-use exhaust gas pressure, but that would involve swing wing designs or some way of slotting the whole thing inside a launch tube. Engine goes off, provides pressure in the tube which should fire the rocketplane out of the end like a bullet from a gun. Wings can flip out and sabots can fall off as the aircraft leaves the barrel. Methinks the SPB team are going for something with less moving parts though, as lovely as the idea sounds, and as epic as the launch footage would be.
Tracking by telescope.
Didn't go so well for PARIS. What about here? Any way of using a radio beacon or something to do auto-tracking?
Re: LOHAN ideas..
How about after burst? Can the parachute be made big enough that the loss in altitude will be less than having to chop the lifting stage short? If it drops 500 feet before the rocket fires, you're still in the money compared with just saying "okay, 60,000 feet" or whatever. Plus you still get to launch if there's a balloon failure before any kind of preset altitude.
Two rails/rods perhaps?
See title. That should contain any rolling quite nicely.
Freezing to the launch rail...
...or rod, or whatever you're sliding along, just to avoid arguments.
I've just suggested this in the last SPB article, but now there's a proper forum for dissecting ideas:
What about using chemical heat pack powder inside a hollow launch guide? The powder will get "up to" 45C according to most heat pack instructions, though the instructions also tend to state "do not disassemble". The ingredients are rust, activated charcoal and water anyway though, so hardly a major risk.
How much thermal expansion the rig will go through can be tested on the ground with a frozen sleeve and heated launch guide. The heat packs are good for anything between 8 and 24 hours when used as sold, depending on what pack you buy. I've noticed the 24 hour ones will take maybe an hour to get to full temperature though.
I did also suggest using resistive wire to make heat, but the various modes of failure plus a honking great battery to melt ice over a 5 or 10 minute period would probably make the chemical powder idea better.
Re: Oh, yeah.
Thermal expansion? The hottest the metal will get using heat packs is about 45C. So you do tests first, using worst possible case scenarios (ground level during a boiling Summer with a sleeve that's been resting in dry ice for instance), to see how loosely the sleeve needs to be fitted to the rod.
It's not like you're going to be needing micron accuracy just to make sure the Vulture 2 slides off the pole without sticking. Personally I'm hoping the rod, rail or whatever you want to use goes through the plane fuselage somehow, rather than through some non-aerodynamic externally-attached clamps. Use spring loaded flaps to close the entrance/exit holes afterwards.
And it'll still likely benefit from some kind of heating. A rod filled with chemical heat pack powder is just probably the easiest - and lightest - option. Remember that the original PARIS used low temperature grease, and that still stuck due to bits icing up.
Re: Oh, yeah.
...that or a chemical reaction. Activated charcoal, rust and water are what's in heat packs. Fill the launch rod with it? Should be good for hours. Just needs to be hot enough to make the outside > 0C.
About that launch rod. If it's hollow, try wrapping some resistive wire around something and stuffing it inside the rod. Approximately five minutes before launch, you have an alarm battery, or some kind of high-capacity LiPo start dumping current into the resistive wire. This heats it up, and removes any problem you might have about freezing the aircraft to the rail.
Re: Why two elevons?
Two elevons because then they can control the aircraft properly. Rudder-only control is iffy at best. Sure it works, for a "you might end up ploughing into the floor at the slightest hint of a gust" definition of "works". Two properly positioned elevons give you pitch and roll, which is all you need. Yaw control would be nice, but hardly necessary when you're going to be landing in a field rather than on some narrow strip.
Will we be having another attempt at trying to track it by telescope? Maybe some kind of auto-tracking tech following a radio beacon on the launch platform, if nobody can be bothered trying to move a scope around manually.
Also, I know you won't get a 3G signal all the way up there, but it might be worth having some kind of data feedback via mobile anyway, for when it gets low enough? Live webcam/telemetry feed from 10,000 feet and falling could be fun. Plus, it could help you locate the various parts a lot quicker than wandering around with a big antenna, signal meter and a map.
Dammit, they disabled comments.
Re: Drop speed limits in Sweden, too.
Now that you mention it, dropping speed limits on some roads is an astoundingly good idea. Some countries already work like that, and I don't see them about to descend into a pit of anarchy.
Really, "we won't follow the headless chickens wibbling about mobile phones" equates with "let's turn the whole country into Barter Town"?
Two men enter, one man leave!
"Chuck us your phone mate, I need to call someone. Hang on a minute while I turn the radio down."
Not saying it's right, but it's a lot easier to borrow a phone than a car. Anyway, I've often said that if you're going to ban phones in the car then you also need to ban radios, MP3 players, children and other passengers.
Well at least it'll make cars smaller and cheaper.
Re: When contemplating the latest generation of high-end smart phones I feel myself..........
It's fit for purpose so long as every single node is running Windows. I wouldn't say it's gotten the job done for decades though, when the earlier incarnations of Windows used to do silly things like turning your entire filesystem and all attached printers into the Internet's playpen.
FAT has "gotten the job done" for a while too. A long while ago, as a bit of a mental exercise, I decided to try and come up with the most simple, godawful, would-lead-to-a-system-fragmented-as-hell-but-it-would-work filesystem that I could think of. Explained it to a more learned person and they responded with "uhm, have you ever read up on how FAT works?"
It was then that I fully understood the ire directed at that filesystem. It is truly awful, a travesty of design that belongs in the twisted imagination of geeks who like to torture their computers. Lately it's become a useful means for Microsoft to turn companies who don't use WIndows upside down and shake them to see what comes out.
It does the job though. Has done for years.
Gateway basically sold shite that nobody wanted.
IBM got out of the PC market that they inadvertently created because they were basically selling under-specced shite in ugly boxes for a huge premium because of the "IBM" tag. Big surprise nobody bought them.
If nobody is making money from Android, howcomes there are still a ton of new Android phones coming out?
Re: When contemplating the latest generation of high-end smart phones I feel myself..........
Samba isn't a protocol. Samba is the open source implementation of SMB, also known as NetBIOS, also known as "Windows File and Printer Sharing", also known as "a godawful travesty that people nonetheless have to support because it's popular".
Well this is The Register. If I can't be pedantic here, where else is there?
Re: Antiquated aspect ratio?
Aspect ratio closer to that of a book?
You ever held a Galaxy Tab 7? It's an airport-size book tablet. Absolutely perfect size and aspect for a paperback, why is it so awful in a tablet?
On what planet is a paperback page closer to 4:3 than 16:9, or do all your books come with wooden pages and pop-up animals inside?
More cynical types might suggest that WW1 was actually about Iraqi oil (how things change eh?)
For more information from one of said cynical types, I recommend Robert Newman's Apocalypso Now, on audio CD or, well, Youtube. Also see Caliban to Taliban and his other various works.

It is not only easy, but pathetically easy to crack a certificate-based encryption mechanism, when you control the certificates.

Re: "It just hurts my eyes," huh?
Human eyeballs are more attuned to green than any other wavelength of light. This means we can detect more different shades of green than any other colour.
I have to say green on black looks nicer to me than white on black, but then that's probably more contrast than colour, since amber works too.
I do like the monitors with the "white/amber/green" toggle switch.
..."smart" phones are basically games consoles with 3G chipsets, and follow a similar pattern: All locked up, and you void the warranty and potentially ban yourself from online services for modding it up.
It's the same all over. Good luck with the search. If you find any halfway decent smartphone with a manufacturer that won't bugger you sideways for using Cyanogenmod, don't forget to tell us all.
Every single iPhone that I hold like a phone...
...exhibits the Deathgrip problem.
Also annoying when you're playing games in landscape mode and the "Network Error" popup happens.
Every. Single. iPhone.
It's not a limited problem. It's a problem that lots of people couldn't be bothered to do anything about. Apparently dropped calls is a minor issue on a device that you can play Angry Birds on.
AT&T are allowing you to dispose of your own property how you see fit.
They surely must be models of generosity for the rest of the world.

Re: Old school FTW
I was hunting around looking for Draqgon 32 viruses, just to amusingly prove you wrong. I can't find any though, and I feel like I have to print something vaguely amusing, so instead you can all have this:
"The Motorola 6809, used in the UK's "Dragon 32" personal
computer, actually had an official "SEX" instruction; the
6502 in the Apple II with which it competed did not.
British hackers thought this made perfect mythic sense; after
all, it was commonly observed, you could (on some theoretical
level) have sex with a dragon, but you can't have sex with an
Icon for comical reasons.
Reminds me of something, that does.
...depends on how you define "thousands". I did once end up cleaning a computer that had well over 100,000 running copies of the same worm, each with its own executable in c:\windows\system. "Slow" doesn't begin to describe it.
And yes, trolling troll is trollicious.
Re: Think you got the wrong icon there.
Yes. Someone decides to create a Youtube account and upload a video of Tom Cruise going Tom Cruise Crazy. This is Youtube's fault how? For existing?
They have a takedown procedure, and it seems to work, by the amount of "video was taken down by a copyright complaint" links I've been directed to. Your problem is that you have a sizeable proportion of the entire planet uploading videos. Believe it or not, that's what Youtube is there for. And your solution is what? Delete Youtube?
Viacom and the rest can go fish, frankly. And that's exactly what they are doing: Fishing for money, because Google has a shitload of it. Who's next, the ISPs? For allowing people access to this magical Internet thingummybobsit that is probably being used to download pirate porn? Maybe we should just shut it all down and go back to BBS links and mailing hour. That'll show 'em.
Re: If by a "certain company" you mean Microsoft...
Better late than never I guess...
Thing is, I wouldn't dislike Microsoft quite so much if they were just another company. If they didn't have the Windows monopoly any more then they might be bastards, but they would be bastards I can walk away from and buy elsewhere.
Even better is the various attempts to keep it that way, bending an already abused patent system to some truly absurd extremes because they can, and nobody appears to be doing anything about it.
Now I could take a Microsoftian approach here about the employees of Microsoft and say "tough shit, you backed the wrong horse", and I really want to, but I won't. I just want Microsoft's role as the troll under the bridge to be negated, and for Microsoft to stop blowing other people's bridges up!
Especially them free open source ones. MS really does seem to be a bit pathological there.
"What kind of saddo gets all emotionally involved with their operating system?!"
You do, evidently.
This is the reg, you know.
ANyway, Linux fragmentation is a myth unless you're trying something stupid like installing OpenOffice onto OpenWRT, or trying Slackware in any shape or form.
Go get yourself a desktop distro like Mint, Ubuntu or Mandriva. Be AMAZED at all the same applications being available through the repositories. Watch your C++ code compile the same on them all. Gasp and clap your hands at LibreOffice or OpenOffice exporting PDFs from machine to machine without even a hiccup!
And then go write an angry missive to El Reg about how people who download stuff from teh intarwebs should all have a short drop and a sharp stop. Go on, I know you want to.
Re: Open Source document manipulation
Emacs? Vim? Lyx? Tex?
You can tell that the Reg Readership on the whole is somewhat insulated from the rest of the world. 99% of the planet would look at that lot and go "fuck this, where's MS Office?"
Libreoffice on the other hand, they could probably cope with.
Re: If by a "certain company" you mean Microsoft...
"Schizophrenia (/ˌskɪtsɵˈfrɛniə/ or /ˌskɪtsɵˈfriːniə/) is a mental disorder characterized by a breakdown of thought processes and by poor emotional responsiveness. It most commonly manifests itself as auditory hallucinations, paranoid or bizarre delusions, or disorganized speech and thinking, and it is accompanied by significant social or occupational dysfunction."
No, I think I got that dot on. I mean, they might have multiple personality disorder as well, but that wasn't what I was implying. What I was, and am implying is that the corporate entity known as Microsoft is getting ever more batshit fucking insane.
Hopefully it'll be their downfall.
If by a "certain company" you mean Microsoft...
...then I'm afraid they haven't changed at all. If anything their attitude to FOSS has become more schizophrenic of late, but they do still seem determined to destroy it.
And they're still failing hard at that.
Still, shows you the truth behind Microsoft's bleating about TCO. "Get The Facts", indeed. And damn, they've taken the whole "Get The Facts" sub-site down. Well that could have been handy.
Just gone and bought one this Sunday, the quad core wifi variety since my phone can act as the access point. Stuffed it in the backpack with an external battery plugged into it and did the upgrade to ICS while biking home.
Damn this thing's speedy. T'ain't crashed yet though, or had any kind of glitchy moment that's any worse than an iSomething. Even a friend who really loves to play his iThings up and tell me how his ePeen is bigger than mine (or words to that effect) seems to be grudgingly impressed. "Bloody should be good for £500" is high praise indeed!
It really, really needs to not automatically put icons for installed apps on the home screens though. I did a sync and it started downloading every single app, paid or free, that I have ever downloaded on that account, even apps that I took a look at and uninstalled ages ago. Opening the thing to see boatloads of crap all over the previously pristine home screens and the system plaintively complaining that there is "no more room on the home screen" for the incoming apps was a bit annoying. There's a big list of apps already available, why do I need shortcuts to all of them?
Relatedly, Google need to sort out a way of telling the Market "I don't want this app, and I don't want it automatically reinstalling itself!"
Re: Google "taking the fight to Amazon"
What does "compatibility" mean?
We define an "Android compatible" device as one that can run any application written by third-party developers using the Android SDK and NDK. We use this as a filter to separate devices that can participate in the Android app ecosystem, and those that cannot. Devices that are properly compatible can seek approval to use the Android trademark. Devices that are not compatible are merely derived from the Android source code and may not use the Android trademark.
In other words, compatibility is a prerequisite to participate in the Android apps ecosystem. Anyone is welcome to use the Android source code, but if the device isn't compatible, it's not considered part of the Android ecosystem.
Re: is it bullshit Friday or something?
Not so much. I don't know if any of the big top 500 HPC systems have the libraries to run Doom 3 installed, but it's still unmistakeably Linux. DItto routers, set top boxes and phones.
That said, there is a certain number of expected things either already baked in or easily available in anything calling itself a "Desktop" Linux.
Re: Actually its the riders that are the problem and not the speed or DoT
See I think the govt here should just declare that riding a bicycle on the pavement is perfectly legal but pedestrians have right of way at all times. That means get off and walk or get on the road if they're in your way.
It would be more of a match for the current reality, where putting bike lanes everywhere would be stupidly expensive and, in the case of a white line on the road, not do a whole lot for safety. Bicycles are the only genuinely free form of transport that exists in this part of the world, can go practically anywhere, and can go for miles on a few cups of water. I'd hate to see that go because some people think that anything useful has to be taxed and regulated somehow.
Re: Tour de France
This is what I'm thinking.
If you actually set the bike computer/speedo/whatever to the CORRECT WHEEL SIZE, you will find it surprisingly hard to maintain (or even achieve) 30mph on a pushbike, regardless of how light the frame or how well oiled the bearings. As someone who really has done 60+ MPH on bicycles, I can tell you that speeds like that on a bog standard diamond frame are scary. Especially going down an 80 degree incline on the side of a slagheap. Half the reason I did it, really.
And car speedos are always a bit shit. Compare what your dash says to what a GPS speedo says and be prepared to be amazed.
3 12V alarm batteries and a 750W motor?
Okay let's assume you're going for some real porkers of alarm batteries at 10Ah each and you're wiring them in series. That's 36V * 10A = 360Wh.
So basically you get about half an hour of juice and then you're fuckered? Still, at 750W that must be a hell of a half hour.
Re: How much is that in
Or Curly Wurlies?
Swearing at the boss.
Not always a sackable offense.
I used to work for Tuffnells Parcels Express as a porter/sorter/general dogsbody. It was the only place I've known where I could tell the depot manager to STFU and stop being so fat and bald, and still have my job. Then I got given the Jesus nickname by an Iraqi refugee who was probably one of the best workers in the place. So he instantly got called either "Mohammed" or "Aladdin" depending on what mood I was in. The night manager was similarly rotund and hairless so ended up being called "Buddha". So I'd walk in, he'd shout "JESUS!" - I'd shout back with "ALREET BUDDHA, WHERE'S MOHAMMED?" Three gods working in one depot, no wonder we managed to work miracles every night!
Of course this doesn't compare to the depot manager shouting at me while unloading "ARE YOU SWEATING YET?"
So I raise my arm, point right at the stained and sweaty T shirt, "LICK THIS AND TELL ME."
His response? "Get this wagon done in the next ten minutes and I'll lick your fucking balls, pal."
Yeah, so tl;dr: How you treat your boss depends entirely on the type of workplace you are in.
Re: So does someone want to tell me how I'm wrong...
Bought by enthusiasts such as a friend's kid who got it home and tried to use it, gave it to me and said "can you make it work?"
I told him to take it back to the shop as unfit for purpose and make sure the next one comes with the Market. In fact there are a number of people who have expressed interest in non-iPad tablets to me and I keep telling them all the same thing: Make sure it's an official build with the marketplace, and a nice new version of Android. If it's not at least two point something, don't bother!
No, I think you'll find there are quite a lot of people who are buying cheap Android tablets because they see the iPad as being too expensive. They then go "WTF is this shit", take the tablet back and decide the iPad must be worth it. It's not because "Android is a phone OS on a tablet." That's a stupid answer. 2.x is a lovely interface on a tablet and you can buy different launchers, unlike a certain fruity tab.
It's because people buy them, can't get shit-all apps for them, and decide Android must be crap, oh hey the iPad 2 has gone down in price, let's get one.
So does someone want to tell me how I'm wrong...
...or are they going to hit the thumbs-down because I'm telling the truth and they don't like it?
Knock off non-androids make people buy iPads. By "people" I mean normal people who want to buy something and use it, not buy something and spend all night trying to make it work properly.
Now if it was managed by your own private server, that'd be more interesting.
Still, at least it isn't made or sponsored by "your property is my property and you can't sell it" Braben.

Re: How to lose customers and annoy people...

Of course you can then sell your banned Xbox to an innocent third party and they get told "tough shit, sucks to be you."
