"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
I've got 6 machines running various version - very different hardware from dual-core atom to dual core AMD to mCeleron. All have installed/run flawlessly.
"Full RHEL6 gcc package takes 3.5 days on SheevaPlug"
You are a star !
"Now i am running OpenSuse"
Always has been for me !
"but space is curved by the various optics"
This is nonsense !
"Because there's just no scope of abuse there is there?"
It's only like ANY other legislation
From LibreOffice help
"If you decide to enter a number directly as a text string, enter an apostrophe (') first. For example, for years in column headings, you can enter '1999, '2000 and '2001. The apostrophe is not visible in the cell, it only indicates that the entry is to be recognised as text and not as a number."
and it works for me !
Re : Why control key
Thanks, I 'd just read it as though it was necessary for SSH.
"wanting to ssh into Linux systems"
Am I missing something ? - I SSH into my Linux systems all the time without a control key.
"between tinkering with the engine and driving to the shops."
Trivial beyond belief !
Having spent YEARS protein modeling, designing PCBs and writing software then all I can say is that internet access is a great addition but NOT the only use for my computers.
Not all will be sacked ....
for how can any business manage without HR ( now to be renamed Robot Resources) ?
By the way..
the greenhouse effect increases HEAT retention but heat != temperature. For example the same amount of energy might raise a cubic meter of air by x degrees or a cubic meter of water by y degrees depending on the Specific Heat of the materials involved. The more telling example is that ice at 0C will not change in temperature until sufficient heat has been added to melt the ice.
It just shows how complicated a picture it all is. It looks like it is difficult to calculate the balance of heat in v. heat out. Approximating the resultant temperature change must be a nightmare.
years ago I had £50000 transfered into my account ( this is when £50000 would have bought a nice 4-bed detached house in good area), unfortunately a few days later it left just as quickly.
Re : Patented salt?
One patents a use : the actual chemical compound is an example that is suitable for the use.
Well-known salts like sodium chloride can be included in a patent if a new use is found.
It keeps plain text passwords in memory - good grief !
