"the important system routines that are analyzing..........."
That had a certain 'Hitchhikers" feel to it.
"cannot run Crysis"
On the other hand bash commands are quite quick.
"Cant believe the difference in quality and speed"
Do you mean you can talk much faster ?
Trust and Microsoft - two words that you don't see together without Don't in front
Who on earth downvoted this ?
Well I'm using a Three 3G dongle (Huawei E367)
and after 2 months intermittent use in various parts of the UK I'm very impressed (and I've still got most of my data allowance left )
Works fine on both a Linux laptop and netbook.
"Note just under 19 cars require a MW of power"
I think you need to check your figures - at ~9 kW I make it 111 cars/MW - I think you might have divided by the six hour charge time which isn't relevant.
The power they require is ~1MW for 111 cars. The energy consumption is ~1MW.h for 19 cars if the charge time is 6 hrs
I can only add that our (UK) house which is moderately large and uses electric cooking averages a consumption over the year of 4 amps - any significant numbers of electric cars are going to swamp the grid with demand
"The equation to use is E=MC (squared)."
Please don't post on issues you clearly can't understand
'Cos I can go online with my ( mainstream UK ) bank and send money to my Swiss current account with a few clicks and a £10 fee. I've used it for other transactions too.
"If you ever dragged a couch for the missus..."
That comment gives away the fact that you're not married. No self-respecting wife would accept a computer program's view when there's real work to be done
"if each pixel emitted just one photon"
I guess you already know that each pixel would be MUCH less than the size of an atom and as visible light comes from electron orbital transitions around atoms ....
"I want 1.57E33 ppi!"
You sir are a Planck !
"What would you rather? Your bank runs its ATMs on Solaris or Red Hat"
ANY time, absolutely any time
I rely on a complex 20 digit password for access to my SSH account.
BUT I also use a non-standard port and and only allow access to a very unusual username. Every bit helps even if it just hinders most of the automated probes
"I am disappointed with the way desktop Linux is going"
I use OpenSuse 11.4 on 6 machines with KDE and it all just works
Don't know what the rest of you all are doing.
Java, Flash, Silverlight ..........
"measured speed of those neutrinos"
This has nothing to do with speed of light or neutrinos - it's another test of General Relativity
"executable bits and such won't apply to an Adobe vulnerability"
They will on my system 'cos there's no Adobe.
"over major swaths of linux"
Well on my OpenSuse installations neither Firefox or Thunderbird will allow executables to run by just clicking and even if you save the file it's set as non-executable so you really have to have a death wish to run an unknown binary. It doesn't matter at all what the extension is.
It is possible to have FF etc set to run interpreted files if you really, really want to.
"330m* piece of (tight) string if I pull one end the other end doesn't move until a second later???"
Correct if that's the speed of sound in whatever medium.
That answers both questions.
(should be easy enough try with string - not sure about the neutron star rod)
"What if I pulled on the string at faster than the speed of sound in the string?" - I think you might snap the string.
Common sense or "gut feeling" is not always a good guide to reality. To some extent that's why we need mathematics. Try reading about chaos theory which doesn't deal with the very small like QM or the very fast/large like relativity but still provides some really weird and wonderful effects in the everyday world.
Sorry - shouldn't really call it chaos theory
Non-linear dynamics is better
"oes not the string tied around Alice's wrist in Gran Sasso not tug"
Effect propagates at speed of sound in string or whatever material you use.
how do they know the starting time as these things are so hard to detect or have they got a fast gate in the beamline. No it can't be that as the little devils would just go through it. Must look it up
"go a bit funny in curved spacetime"
as does Mercury's orbit - which is not predicted by Newton's gravity but is by GR
"So time flows that way for you " or similar
As a scientist ...
and someone who writes LOTS of terrible code I generally agree.
I have however met some great programmers who were once scientists
On Earth with 1G
your head and feet are so far away from the centre of gravity that there is little differential effect. In a small radius centrifuge there is. That would be far from physiological.
There's also the problem ..
of small radii generating a MUCH greater differential force head to foot so that blood pools in the lower limbs.
If by that...
you mean a rotating system it has to have a considerable radius otherwise the force acting at head level is considerably different to foot level and can't be compensated for so blood pools in the legs.
Staying in bed is just lazy and
Gravity is still Earth normal not zero G
I assume that ..
this would still need a mechanism to harness the energy to produce the considerable thrust to get the payload off the ground.
Depends on how much you are buying but ~£4/L - this stuff is used all the time with superconducting magnets. Chemistry NMR instruments hold ~~ 100L
Incidently the LHC uses ~120000 kg or ~~ 650000L I believe.
On another point (although I wouldn't recommend trying this) a stream of liquid nitrogen droplets will bounce readily off the skin without harm due to the boiling liquid being insulated by a layer of gas. As the skin cools however then the problems start. We used to use these types of materials without gloves as any finding its way down a glove could easily produce a nasty burn.
"basically, anti matter are organised in bubbles around galaxies."
Should read ...
"Your PC ran into a problem that Windows couldn't handle, and now it needs to restart."
I take it you've already
... deposited your penny and booked your table.
"it will just take a long time to get there"
How long have you got ?
Even if you can manage 10000 km/sec it will take ~120 years and you'll need >5E18 joules to accelerate to that speed in even a 100 tonne ship
"we(IT bods and bodets) are supposed to be the champions of change."
I think you're supposed to be champions of IMPROVEMENT not change
As far as I know depletion of ozone depends on ..
chlorine derived from CFCs.
The actual reaction is atomic chlorine + O3 -> chlorine monoxide and oxygen.
Unfortunately chlorine monoxide can react with oxygen atoms of which there are some in the upper atmosphere to regenerate chlorine atoms to perpetuate the cycle.
ClO + O -> O2 + Cl
A Non-fluorine containing material such as carbon tetrachloride is also an ozone destroyer.
I've not gone into the details of this ..
.. but I'd *guess* the patent is for the control of an application by gesture on a touchscreen NOT for the software to implement that. After all it could be by an ASIC or some other means.
Still thin-end of the wedge-ish
In the first Foundation novel (~1951)..
Hari Seldon's (?) new recruit, Gaal Dornick, wasn't offered the use of Seldon's 'calcPAD' or something similar to do a quick bit of psychohistory prediction.
It doesn't record if it was a calculator-like device or more like a tablet
To use an old joke
Moses was the first man to ride a motorbike too
"For the roar of Moses' Triumph was heard throughout the land " or similar
Sure, my workflow would be twin Xeon Linux workstation, if need more grunt x86 Linux farm (1024 nodes), finally supercomputer somewhere.
The scientific community
are most likely to use Linux workstations, Linux farms or supers running Linux.
Sounds very high to me too.
It'd be costing ~~£150/year
Coming from the other direction I worked out ~180kg coal (~~equivalent to 630kg CO2) spread over the year would generate ~~30W which still seems high
For the FORTH fanciers
Did you get the feeling that your VLIST flashed before you ?
Plenty of people are thinking about ...
Fuel cells (although AFAIK not chocolate powered ones)
Seriously it's just a device to show how poor the energy density of batteries is compared with (say) the equivalent weight of hydrocarbon. It's only the same as electric car range 50 miles/ diesel car 600 miles
Assuming that chocolate is ~100% fat & completely oxidized
1g = ~37kJ
So the chocolate equivalent of my 300g laptop battery would be ~~11MJ
That should keep it going a while !
Reminds me about the time ..
I wrote a 6802 assembler in 6809 BASIC. Took ~2 hrs to assemble ~ 500 bytes
