Re: @M Gale
"Scientific enquiry in the modern sense was more likely to arise from monotheistic belief in a universe governed by God through laws of nature, than from polytheistic or atheistic belief in an essentially chaotic and capricious universe."
A bit like the Greeks, who were quite advanced for their time despite having an entire pantheon of gods. Or maybe the Romans, who adopted monotheism at about the same time their entire civilisation went kaput? The Egyptians performed some minor miracles with a sound knowledge of building materials and an almost endless supply of cheap, disposable labour. Oh, they were pretty polytheist, too, what with horus, ra, and set and all the rest.
The key thing here is that religion served to concentrate wealth and control. Once that had happened, one person with a brain can control an army, if they believe said person has some kind of godliness in them. It's okay to waste 100,000 people on a bloody big triangular coffin if your local collection of sky-fairies say it's what you're supposed to do.
I will reiterate: Religion has not served to advance science one iota.
...and what's this about "belief in a chaotic and capricious universe" being an "atheist" belief?
Re: This could bite them in the arse
What Skrrp said.
Basically, religion has done nothing, at all, to further the field of science. Some religious people have been involved in the scientific process - I do believe Newton was also an alchemist who fervently believed that you could turn base metals into gold, and had an interest in the occult to go along with it - but the religious process of "I have faith therefore it is true" has accomplished nothing asides maybe some periodic repression and warfare.
Notice how Newton's theories on alchemy aren't discussed by anybody except as an academic exercise? Because they are scientifically unsound, a bit like a book that tells you to lock your women up, or another one that bans wearing jeans for some reason.
I will reiterate, religion has done nothing to advance science, has held it back in a few places, and religious texts have zero predictive value.
Re: This could bite them in the arse
"Islam has been a driving force in science over the years."
Really? What new theories can be attributed to Allah?
I throw that one open to the other sky-daddy worshippers too.
Re: Google Calling the Kettle Black
"Oh, and my ROM is..."
Hate to say this, but this immediately discounts everything you've said.
Standard options please. My mum recently got an Android phone with her contract, but if I said "you can root it and install Cyanogenmod" her answer would be something like "I understood everything up to the word 'can'."
Still, it's not like the stock ROM won't allow you to install Firefox. Or Opera. Or Dolphin. Hell, I even have MX Player Pro for my videos, and I'm looking for a better music app because Google Play Music is desperately awful shit.
Desperately awful replaceable shit, I must reiterate.

"This is just more astroturfing BS from Microsoft's PR dep't."
Actually if you bother to look at the guy's posting history, he seems to be more of a very badly informed Apple fan.
Or maybe that's part of Ballmer's master plan!

Also I wonder how are Microsoft going to stop Google and Mozilla? An Apple-esque "our way or the highway" app store?
Well fuck that shit, then.
Still stupidly pricey...
...more pricey than getting an el cheapo throwaway SIM from the country you're going to and using that for the duration.
Re: muggers, get yer smartphones here!
Or alternatively, any phone with wifi?
ZTE Blade. Real high end, that one. I can see it fetching a pretty penny down the local pub, a whole £2.50 or so! That's assuming it's not loaded up to the hilt with tracking software and the owner isn't about to appear with six friends and a baseball bat.
Smartphones. A risky business for a thief.
Because Tesco is 5 minutes away...
...and delivery takes longer.
Ditto Aldi, Iceland, and at least two or three local computer shops. I get stuff from the Internet when I can't find it elsewhere, but I'd really rather shop at a physical store. That way when something goes tits-up, I know where to take it back, and it happens straight away and not after a couple of weeks of fucking about, spending money to insure stuff by next day special delivery, hoping the other guys got it and waiting for the credit to your bank account that might take a while.
Now if you're 10 miles from the nearest shops and have no transport, I can see delivery of Internet-ordered groceries being advantageous. Otherwise, not so much.
Re: Don't knock the old phone boxes!
Never used a phone box in your life and you're "only" 30?
Laddie, I'm not much older than you and I distinctly remember being on an exchange that was crap enough that you had to dial the operator for a trunk line so she (was always a she in them days) could do the whole plugging-jack-leads-in thing.
Was fun when someone hacked the local phone box to play a few minutes of radio when you dialled 147. More fun when we had to leg it with speed at a BT van turning up after a bunch of us had sat around the phone box for an hour repeatedly dialling. Hey, I was 6 or 7 years old, do you blame me?
Err, kilohertz, not hertz.
40khz is well into the ultrasonic. 44.1khz is the sampling rate of a compact disk.
Maybe I should have said 40,000hz?
Put an 18khz noise out loud enough and I can hear it, and I'm in my 30s. I know the shops that have those stupid, ineffectual "anti-chav" sonic weapons installed on their premises because they affect me too. It's like sitting next to a really loud, broken cathode ray tube. Nice to know I'm having my hearing potentially damaged and it's all okay because it's been scientifically tested, and stuff.
Make the noise closer to 40khz or so and you'll be safely out of the range of human hearing, but good luck to anybody with a pet who buys one of these.
Re: Next step...
Wouldn't that be a gaser cannon?

Notes to block VPNs
What notes would they be? "Oh, there's the exit points, we'll block them"?
And within a week, new exit points spring up. Well done.
Maybe some people will see sense and just let Global Mode be. Of course, those interested in carving markets up into artificial geographic divisions will carry on trying to prevent it. All that stress and high blood pressure, and for some cheeky sod to work their way around your latest filter like it's not even there? I'd be pissed off too, but I don't imagine many people would be sympathetic.
Re: There can only be one...?
The reason Apple still exist is because Microsoft gave them a rather large chunk of cash in return for shares. Whenever Apple make money now, Microsoft make money. Kinda makes me wonder why Ballmer is bothering with mobile at all.
Re: " While Apple is crushing competitors in the relatively new tablet market,"
Real keyboard on a detachable dock, laptop-style mousepad for people who hate touch screens, 4.5 core Tegra 3, massive battery life, lovely screen, more points of multi-touch recognised than you have fingers, brushed aluminium case, USB port for mass storage and other devices, micro SD port, full size SD port, 32GB built-in storage, ICS for people who really want that sort of thing, a whole load of brilliant apps available and the computing power to make everything fly. It's the only fondle-toy I've seen yet that I would be comfortable typing more than 100 words on, and your choice of RDP or VNC clients from the app store (I go for Remote RDP, myself) means you have a desktop away from your desktop.
Just off the top of my head, like. As for why its marketshare is "in the pit", I dunno, is it? Just goes to show that following the crowd isn't always the best idea.
Re: Thrust driven swing wing
WRT v-tail, I was on about losing the entire stabiliser. Given independant servos, you've a chance of bringing an aircraft in with half the stabiliser gone if it's a nice airframe. Lose half of a v-tail and you're pretty buggered.
Anyway, the glide ratio doesn't need to be massively brilliant at 100,000 feet. With the wings swept back you could go for a high-speed descent, tearing toward the landing site like some NASA black ops test vehicle until the atmosphere becomes thick enough to support a more gentle glide that won't tear the bottom of the aircraft off when it hits the floor.
Plus, you know, added awesome, and all.
Re: Thrust driven swing wing
Well as I was suggesting, there isn't all that much extra complexity on a model scale. The transmission can basically be two fishing lines attached to a relatively strong servo toward the tail that's powerful enough to counteract a spring that'll keep the wings straight at 50, 60mph or whatever speed you're going to go to "fully extended". Having wings of a reasonable size would mean a much better glide ratio, even if you don't think drag during the rocket burn on smaller fixed wings will be a problem. I'm not sure how much wind resistance there is at 80,000 feet, but once the rocket has been burning for a couple of seconds I'm pretty sure LOHAN's velocity will be enough for even that rarified atmosphere to start tugging on any sticky-out bits with quite a force.
As for the aileron linkages, any decent model has a seperate servo for each control surface, usually with one for each aileron mounted inside the wing, forward of the aileron. These can be mixed either with a physical onboard mixer or in the transmitter (and presumably in the open source autopilot the SPB team are apparently using). It also allows ailerons to be flaperons (and elevators to be elevons) with a bit of clever mixing. At 9g or less for a decent micro-servo it's not going to be a bother on a craft of LOHAN's, erm, proportions.
Having ailerons would also mean you don't need a V tail, plus I've seen models land safely after losing one of their elevators completely. Little harder, especially for an autopilot, to do that after getting a whole wing torn off.
Also, try and make the autopilot aim straight up half a second second after leaving the platform. Use some kind of umbilical jack lead, or maybe a powerful magnet stuck to two contacts on the aircraft as an easy way to detect a launch. You also get to keep the aircraft's lightweight batteries topped up with something more heavy duty in the launch system that way. Yes, it probably won't give us much additional altitude and yes, there isn't much air up there but it's going to have some effect and it'd still look cool on a camera. Plus it might limit the damage of an odd launch angle.
Last thing, uhm, have you considered apogee detection? I'm sure you'd like to go from burn mode to glide mode in the most efficient way you can.
Re: Thrust driven swing wing
On a model scale I'm not sure if a swing wing would really be that complex. You need a thick enough peg-like spring to bear the wing (or one length of metal coiled in the right places to mount both wings to), and some fishing line attached to a servo somewhere via a couple of pullys off a model yacht or whatever. Shape the body with the first couple of inches of wing built-in so that the sprung parts are supported and won't wobble about on the single spring holding them on. Obviously the mounting points for the springs will need reinforcement, but the wing struts should be pretty reinforced for a rocket plane anyway shouldn't they? This also means that you can tuck the wings right back against the body for the launch, and then use airspeed and altitude to decide when to start slowly loosening the wire.
Now if only I had money, a laser sintering thingummybobsit and some time I'd test it myself!
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.
second hand software not allowed in any other industry?
I call shenanigans, to put it politely.
What pisses me off isn't copyright. If somebody wants to try and sell their new sparkly word processor at £500 a pop, I honestly couldn't give a damn. I might point and laugh at them a bit unless it really is worth every penny of that huge price, but it's hardly worth posting Angry Bloke comments on a web forum about.
What pisses me off is using copyright or, lately, the even more broad patent concept to control just about everything you can about how people use their products that they bought from you. What pisses me off is after shelling out a shitload already on a decent computer, there's a tax to be paid to Microsoft if you want to use any kind of widely-available software. The continuous attempts to destroy rather than encourage interoperability by shackling every possible means to do so behind patent taxes and threats is a disease, and Oracle's behaviour towards Java on Android is yet another example of this. They didn't invent the language, they bought the business and then started trolling everyone.
So remind me, just how well is this working out for us, Andrew?
We live in a society where greed is encouraged...
...and you blame the guy?
He wasn't a domain squatter. He was using the domain since before Google decided to buy Gmail. That he tried to get the highest possible price he could from an entity that is hardly strapped for cash is not reprehensible under the circumstances: It is commendable.
I hope the courts at least forced him to sell it, not give it away. Not that that's much better, mind.
What, don't you have any domain names yourself? I wonder what happens if in a few years a new "Google E" service comes out and they want your domain name for themselves? You going to just hand it over, or are you going to grab every penny you can, assuming you even want to sell?
"Your honour, they may have bought it first, it may be theirs and they may have paid for it, but we're more well known and we have money."
Well damn, we have to sort this right away!
After all, I don't think "Cadbury's Carob" has quite the same ring to it!

Re: Proper PC version please!!!
You did play the game with the extra 2GB or so of high-res assets you can download, right?

Re: 1992 called. They want their network back.
"Yeah mate, just getting in the back now. Driver, airport please. Look I'd like to continue chatting about this billion-dollar business deal but the stupid phone compan....BEEEEEEEEEEEEEEEEEEP..."
Or perhaps some kind of more humanitarian scenario if money's not your bag. You going to begrudge someone a call to their significant other in the hospital while their mate's blasting down the motorway trying to get there on time? "Calm down love, I'm not sure if I can hold him in but he'll be here when you get here" might be the words that save two people's lives there.
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.
A problem if it's installed I guess.
Though, isn't Backtrack designed to be run straight from the CD/DVD, usually as root anyway?
Congratulations, you just pwned a RAMdrive.
But yes, ironic and all that.
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: 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: 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.
Re: Antiquated aspect ratio?
Aspect ratio closer to that of a book?

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.
