Re: "If the universe were really formed from a single explosion"It's thought that quantum fluctuations when the universe was tiny just after the 'Big Bang' were 'frozen' by the gigantic inflationary process and give rise to the small scale heterogenicity seen On the large scale the universe is very homogenous or symmetric. It's reconciling these two observations that suggested the extremely small nature of the start point and inflation theory
If it's like the electric beetle (85kW electric motor and 28.3kWh lithium-ion battery pack.) if you could manage to drive it flat out it would last ~20mins.
"Can someone please refute this Hawking tosh without further delay??"
What you have just said has nothing whatsoever to do with Hawkings !!!!!
Re: Re re: holidays on the moon
I know what you mean. In fact our holiday home is 1800m above sea-level and nowhere near any sea.
"holidays on the moon"
The moon's overrated. OK the golf is easy but the brochures all go on about the seas and as far as I can see when you get to the beach the tide's always way out .
Ratio of phosphorous to silicon
I can't see how the doping is effective if only 4 silicon atoms are involved - I thought dopants replaced atoms in a matrix - the text and cartoon make it looks like the silicon is smothered in phosphorous

in that case a lot of people are working hard to produce an excellent set of distros.
"many devices out there are not advertised to work flawlessly under GNU/Linux"
I find it just as irritating to be told by a manufacturer that some device 'only' works with Windows 'X' or maybe Apple and to find that actually it works perfectly well or better with Linux.
Recent examples include a USB 3G dongle, a firewire video camera and a USB/serial converter
"name me another distro that is relevant on the desktop"
"the Linux share of the desktop market... less than other"
This might be true but EVERY one of those users have chosen to move to Linux.
In a world where essentially all desktop computers are sold with Windows or Apple OS pre-installed and where most people, in any case, don't care I'd count the desktop usage of Linux as a major success.
"ecause these systems insist that you enjoy doing the computer"
Absolute nonsense !
Well I kind of sympathise
but I have 6 machines running OpenSuse 11.4, a netbook, a laptop, 2 workstations, a fileserver and a desktop in our holiday home.
I don't have a problem with KDE although like you I'm quite happy with more 'primitve' managers
I don't have a problem with sleep mode
I have two printers - a Samsung laser and and Epson scanner/copier/inkjet which both work perfectly and network nicely from the fileserver.
I do agree about GIMP but I often process RAW photos with showFoto
I don't use Windows at all and expect to do everything I want in Linux - these days I find this quite easy.
Incidently I'm thinking of building a compute server to offload a lot of intensive scientific calculations & modeling and also for the transcoding/rendering of 1080/50p video
"They cost a bit more than £20"
@£50 from memory, would have been much more complex to produce and had loads of TTL logic on the board. I've still got one somewhere - the SC/MP machine code was a sod to write!
Re:30000 feet seems rather high
The world record seems to be ~12500m or ~40000ft.
Here in Switzerland Air Zermatt helicopters routinely haul loads of concrete etc. to ~3500m + (~11500ft)
Re:Thanks for signing up just to say that.
Amazing he just happened to be passing really !
Re : @I. Aproveofitspendingonspecificprojects → #
You are both sort of correct.
Winter solstice was indeed 22 nd Dec when the day length was shortest.
However sunset and sunrise move in phase but with a lead/lag so sunset here is getting later and has been since ~Dec 14th but sunrise is still around its latest and it'll be early January before it becomes earlier.
Want to buy a big one now ?
Re: "I am not old enough to have watched the first man set boot on the moon."
I am, and yes they had fuel cells for that.
As for the patent - this is shabby in the extreme. Many USA drug patents have had long lists of compounds which were only synthesised on paper but generally not reputable companies.
Even if I'd not seen examples of other mobile devices powered by fuel cells such as laptops ( and 12v supplies for motorhomes plus the Apollo capsule example this would be obvious in the patent sense anyway.
If Apple care to patent a specific design with some demonstrable advantage then that is patentable. But to just claim fuel cell power for mobile devices..........
"There's a vague possibility of dark-matter particles......"
It could have just been a proton with a very-close-to-light velocity.
Even in the LHC the protons have ~1 micro J energy. They wouldn't have to go much faster to reach 50 J. They would, of course, have had to have been accelerated by a mighty powerful mechanism but the universe is likely to have quite a few of those.
Re : Overhead power
Given that vehicles heights vary up to and beyond 4m a car would have to have enormous mechanism to reach the wires which would probably have to be 5m+ above the road.
As mentioned above overtaking would be impossible with multi-lane roads thus reduced to multiple single tracks moving at the speed of the slowest vehicle.
But the battery is 24kWh...
So either the range is conservative or the something is wrong
"What's the range like if its not flat?"
I can't answer that except with a diesel example
My 2.0L Touran averages about 55mpg but climbing the 27km from Visp in the Rhone valley to Saas-Fee ( diff in altitude ~1200m )it does ~28mpg. Coming back down it's more like 120mpg. Now, of course, you can't just average the mpg but I calculate that it's about 45mpg overall.
With regenerative braking an electric car might well get quite a lot closer to it's flat value
"I reckon it won't be more than a quid or two."
It's got a 24KWhr battery so if it was flat it would be ~~ £3 for a full charge unless it's done off-peak
"given the symmetry requirements."
I take your point,of course, but I don't see the symmetry if only one has "dangly bits"
"No, it means you have made the error of reducing the sample space early"
You have made the error of not noticing it was a JOKE !
"They really ought to include PowerPoint training"
They really ought to discourage PowerPoint usage in science degree courses.
Fixed it for you !
The slide mentions the "Look-Elswhere-Effect"
Is that a cousin of the "Somebody-Else's-Problem" field ?
"No matter how intelligent a person"
I agree entirely with that.
I worked with an extremely intelligent chemist who could think & rationalize well outside his area of expertize but he thought computers were binary - it never crossed his mind that you could parallel the binary logic and make 8-bit,32-bit etc,. systems.He assumed it was ALL serial.
"Goes to show just how heavy that ice was"
I believe that GPS based altimeter readings show the SW of England rising and falling each tide by a measurable amount due to the continental crust being pushed down by the increased weight of the sea.
Re : It just doesn't seem to ring true that the climate system is so sensitive....
CO2 absorbs outbound infra-red radiation thus heating the atmosphere more than if it were not there. It's totally irrelevant whether this occurs at .003% or 1% - it depends on the gas. In the case of CO2 0.003% is significant.
However HEAT != temperature. Different materials have different specific heats and worse than that ice/water has a large energy involved in it's phase transition ( ice at 0C + lots of heat > water at 0C )
"CO2 levels != global temperature."
As I've pointed out before rising CO2 levels should cause retention of more HEAT - simple physics
but the relationship between heat and temperature on a planetary scale is likely complex - a very simple example is that you can put lots of heat into ice at 0C and it will stay at 0C until all the ice has melted.
"so much bone damage that it can usually only be done once"
Whilst I agree that it's difficult I do know of 2 people that have had 3 hip replacements. Takes quite a bit of doing and can involve bone-grafts
"or stops the growth"
Good question. It is controlled in normal bone repair but quite how ...
Even more astonishingly normal bone is constantly remodelled by osteoclast cells that attach to the bone, dissolve away the mineral part, enzymatically degrade the protein matrix and then the 'hole' is refilled with fresh protein by osteoblast cells . The protein matrix acts as a scaffold for calcium ions in the blood to deposit and remineralize the bone.
The process may stop naturally as all the protein is covered calcium but I'm not sure about that.
Re : At warp5 it will take 4.8 years to get there
Pity it's just a fictional means of travel !
I know it not the same ..
but UK Parliament is also available as wmv format which can be used by Linux browser plug-ins
"Linux isn't an entertainment OS"
Strange - it seems to be from here.

"giant mutant" before space goat
$1,000 for a 128MB memory stick
Not for the MoD I'm sure
"The price is about nine times what one might expect" - I'd expect not to be able to buy such a small one anymore
Do you mean 128GB ?
"with the clothesline outside"
Just use a rotary drier.
( When it's not being used it could make the craft look more like a 'real' spaceship which everyone knows bristles with that kind of antenna)
Halt and Catch Fire
I think that was Motorola 6800 or 6809 CPUs - I can't remember
this is a laserjet issue I understand
"a component used to dry ink"
That'd be the fuser used to melt toner onto the media
Re : Re: Ah !
I've still got a chart of the (gigantic) number of op-codes on my study wall. Spent a long time writing 6809 assembler including a floppy disk driver & formatter for my home-brew Forth system
Simpler days !
For those who wonder why Branch Always is useful ..
Using a sub-set of 6809 op-codes you could write true position-independent code and I think BRA was the JMP relative version of JMP
6809 - yes !
"Don't these things get used in labs anymore"
Less and less - they use an enormous amount of water unless a pump recirculates in a closed system.
"not a 15mm reduction from atmospheric pressure."
A lab water pump will get to ~~15mm Hg absolute .
