Is it me
or does the Oracle drone's letter sound more like the language of a phishing e-mail ?
"Open source cars?"
Well I'm a Linux user and I can hack-up a C program with the best (of the amateurs).
But I am really a chemist and I wouldn't like any amateurs playing around with the sort of chemistry necessary for batteries that have any chance of reaching the energy density of petrol.
Re : Sir → #
Unfortunately the experiment you ask for should really be to replace the sun with something similar that has a constant output and then see what all the shenanigans on Earth does to the temp/climate etc
It's not coming out of my research budget by the way !!!
@Chris 3 & AC
Not sure what your points are. Guy was positing that it's correct that almost all warmth on Earth comes from the sun - I agree
You both seem to have missed the simple point and veered off onto other things - in the case of Chris 2 in rather a patronising manner too.
You can't grasp how an increase in incoming intensity (In the right area of the em spectrum, i know overall intensity is down) can cause an overall increase in temperature?"
I can grasp it quite clearly - just don't know what it's got to do with this thread - the article & research yes
By the way "The Greenhouse Effect" is conjectured to increase the amount of HEAT retained by the Earth system. How that happens to relate to temperatures is probably a lot more complex.
Re : Surely ..
Quite correct - would the downvoters care to explain ?
"keep Linux -- with its race conditions..."
I'm sure Amazon, Google and all the others, esp. the supercomputer owners must be desperate to move to this wonderful new Dead Dog - if what you say is true ?
"Goats have been producing silk in their milk for several years"
Indeed they have but the yield is ~~1g/litre of milk and the product needs chromatography to purify it and seems to be used for very high performance (expensive) applications.
Are you sure your carpet isn't mohair - the silky fabric from Angora goats
"a car in sight is so much car company BS"
I take your point but to be fair I travelled down the A26 in France on the 22nd Sept. in the middle of the day and there were no other vehicles for as far as the eye could see for long stretches.
On the other hand I went from Saas-Fee over the Simplon pass last week to Locarno and there were road-works & heavy traffic much of the way.
"With the money you save you could hire a better CEO"
Or TRY and write a better OS
I repeat - if you can't get OpenOffice to open documents ~ as quickly as Office then it's not been set-up correctly.
Changing a few settings to save the cost of Office seems a small price ( esp. as I've got it on 6 machines ). In any case Office isn't an option as I'm an all-Linux operation. Whether under Windows OpenOffice is slower I can't test now but I DO know the kind of times that are quoted, if true, don't match my experience or many other peoples either.
Where I have found OpenOffice slow is using large spreadsheets - but in my previous life Excel wasn't up to it either as I used millions of rows so needed JMP.
"Petrol is volatile when it's in a gaseous form, but in a..."
I think you need to look up the meaning of volatile
"setting it up properly?"
Enable systray quickstarter in Options memory
Don't use the Java environment under Options Java
Loads a 70K spreadsheet including starting OpenOfiice over the network via wireless in 10 secs on a Celeron mobile laptop - mind I'm using Linux
"that selectively remove metals from soil"
Don't think so. There is an isotope effect on chemical processes but it is only really significant at large atomic weight ratio differences e.g hydrogen v. deuterium. Separating U235 from the rest is still going to be awkward.
"How fit must you have ....."
Just outside Zermatt is a 'test run' for candidates for climbing the Matterhorn. From memory it goes up very steeply through rough,loose terrain for ~~600m height or about the height of the mast. If you can reach the top in (I think) one hour you might have the stamina for the ~1100m up the Matterhorn from the Hornli hut.
Re : Am I mistaken...
Forget weapons - the contents of the reactor would make a VERY nasty dirty bomb
Just what we need - a mobile nuclear reactor that's capable of being hijacked
"if you want to insist on using Linux exclusively,"
I DO use Linux exclusively.
"don't want android to become another untrustable OS like windows."
Don't install untrusted stuff then. - it's the same for any operating system
I run Linux exclusively but it doesn't mean I trust anything just because it's there. If I did a user account could get compromised and that might lead to worst consequences
"And then ARM being bough up by MS as an attempt to stop linux."
Except all those other licensees might have other ideas.
Re : Yeah store it on the internet
If it's well encrypted it doesn't matter where you store it
"GIMP remains inferior to Photoshop, and Openoffice......."
In absolute terms that may well be true but in value for money ?
In any case most people will find they are more than enough for their purposes.
Re : Ehh?
So what else are they?
Strictly quanta of any wavelength EM radiation AFAIA
@ Keith T
Are you joking ?
30 amps * 220 volts is 6.6kW so in 3 mins. you'll get (at 100% efficiency) ~0.33kWHrs. That's not going to get you very far as from what others have said it's less than 1% of a Tesla's battery capacity
(BTW do American systems include 220V - thought it was all 120V )
Re : Oh how we laugh #
I salute you Sir - not afraid to use reason or logic.
By the way the efficiencies of electrochemical processes fall rapidly with increased rate. This will result in HOT batteries. Even if only 10% is lost as heat then 80kW needs to be dissipated in 3 minutes
Re : Dop cars still use carburettors ?
Old ones do and Grease Monkey said "My advice is that should you stop at the top of the Stelvio pass to take a photo, do not switch off the engine of your aging Beetle"
Re : Re: Rule of thumb
And now I've finished breakfast ...
The very conservative estimate for the energy to start an engine I gave above is equivalent to 0.5 grammes of diesel (~45MJ/kg). Even allowing for inefficiencies that's still a tiny amount.
My guess is any starting problems encountered on the passes where the result of a hot petrol engine evaporating the petrol in the carburettor at the low atm, pressure
Re: Rule of thumb
"The bigger the engine and the....." - the MORE fuel it uses at IDLE . Many car manufacturers offer automatic stop/start in Europe - they will have researched it.
Your evidence is .....? No, thought not
Back of spreadsheet calculation using very rough figures.
Starting amps 1000, time 2 secs = ~7watt.hrs - that's really not very much at all. On the other hand I can watch the fuel drop at idleon the trip computer.
And BTW, I've a holiday home in Switzerland at 1800m (5800ft) and the car ( VW turbo diesel ) starts fine even at -15C.
Re : Wake up →
Displaying your ignorance on The Reg - even if driven by 45 years - . is not a pretty sight. A billion used to mean a million million in the UK but was replaced by 1E9 years ago (~1970). Quite a lot of people still don't believe this and indeed it has been the subject of debate on The Reg.
Re : adding more and more H2O - water vapor to the atmosphere
Take one large continent, drench in heavy rain, allow to dry in wind and sun, repeat for thousands of years.
That's a lot of water vapour added to the atmosphere esp. if the amount the winds drag from the ocean every day is included
Re : they every considered how much fuel is used in recharging...
Far less than leaving your engine running.
The rule-of-thumb is turn off if the wait will be >10secs.
Re : Allways have that argument without merit
I can see your point however the nightly backups I use that are driven by root processes and protected by root privileges are what allows me to sleep more easily with regard to my more important data.
Just reading this it looks as though the safety of the plane depended on a central computer. Surely a plane has a log book that pilots should look at. I'm all in favour of IT but whatever system is used needs to be adhered to
Re : How does a neutron star have a magnetic field
As far as I'm aware a neutron has a magnetic moment, so although overall electrically neutral the basic constituents of the neutron (quarks/gluons ) are able to display their individual properties to some extent.
"use 120v, not our 230"
"So what difference does that make to cutting bills by those methods over here?"
None at all !
Watts=Amps*Volts So lower volts = higher amps.
** Slightly higher waste in the appliance cables in USA
Yes. My fileserver is in a case I found in a skip. This has welded lugs and a metal bar to take a padlock. so you'd need a hacksaw or crowbar. ( The dual core Atom ITX board and dinky power supply and disks occupy about a quarter of it.)
Security not an issue with this anyway due to no easy access.
Re : No need
Not fast though - esp. with a locked case like I use - serious lock that is.
Wouldn't help with a Linux password anyway. But as others have already said if you have the physical machine you have the contents unless they are also seriously encrypted.
"when presented with an actual computer to reboot it into a CD or USB..."
Even with booting disabled from CD/USB/SD and the BIOS locked ?
