usually you calculate the energy density in MJ (megajoule) per kg (Kilogramm).
Depends, burnup specs for nuclear fuel are usually given as MWdays/tonne. For electric energy systems, kWh per given unit of weight is a more natural form than MJ.
Last time I checked PEOPLE, NOT CORPORATIONS enjoyed constitutional protections such as the 1st Amendment.
Hate to burst your bubble, but there have been several court decisions stating the corporations do indeed have freedom of speech protections granted by the first amendment. This is because corporations are considered to be legal "persons". Don't think this will help Diskeeper.
You're probably right about the licensing issues. Having the appropriate version of StarOffice would be very useful to someone in need of conversions. The extra import filters were one of Sun's selling points for StarOffice over OpenOffice.
When things get to the point that Open Office starts culling formats,
Compared to StarOffice 6, they already have. SO6 could import the likes of Lotus Manuscript (which is probably still better than the latest version of M$-Weird for handling long documents, Ami-Pro and a bunch of stuff from the 1980's.
Open and well documented binary formats should be OK, e.g. there are so frigging many devices that read or write to the JPEG format that devices that read the format should be available for decades. As an example, up to about 1980, most consumer grade record changers could handle 78 RPM disks, even though the format was obsolete in 1950. Similarly, it is still possible to purchase turntables that will handle 7" 45 RPM records - a format that was introduced in the late 1940's and passe about 1980.
er... By that logic since Switzerland did not declare war at all, July 1940 is legitimately 'prewar' for them too?
Since Switzerland didn't declare war, "pre-war" is a non-sequitor for them. The US was still pretty much on a peace-time economy in 1940 and full war time conditions didn't start until December 1941.
I agree with the Chinese viewpoint that WW2 started in 1931 as there was pretty much continuous fighting taking place there until 1945 - the US had sent the "Flying Tigers" to help out the Chinese prior to the Pearl Harbor attack and a US gunboat was sunk by the Japanese in 1937. The Eurocentric view is that the war started with the invasion of Poland by Germany and the Soviet Union.
On the gripping hand, there's always Pournelle's view of 20th century Europe and the 70 year war that started in 1914 and ended when Yeltsin took over the Soviet Union.
Since the US did not declare war on Japan until December 8, 1941 (and Germany on December 11, 1941) July 1940 is legitimately pre-war as far as the US is concerned. BTW, the first US casualties from WW2 took place in China in 1937.
As others have pointed out, the Earth's magnetic dipole field extends well past the atmosphere, so the reconnection events take place in vacuum, not the upper atmosphere as on Mars.
The other reason that Venus and Earth have substantial atmospheres is that the gravitational fields for Earth and Venus are stronger than for Mars (or Mercury). The result is the escape velocity is much higher and atoms are much less likely to escape Earth's gravity than Mars' gravity.
Don't forget that a researcher recently (2007)discovered that flu viruses propagate best at 41F and low humidity. As someone on/. commented wrt this discovery, in case of a flu epidemic, he is going to spend as much time in heated and humidified environments.
Isn't that rebutted by basic physics? Both signals follow the simple inverse square law. A TV signal 50miles from the tower is 1/4 the signal strength of the signal 25miles, while a device 50m from a set is 1/25 the interference of a device 10m from a set.
You obviously don't know much about terrestial radio propagation. Depending on the heights of the transmitting and receiving antennas, the interventing terrain, amount and type of vegetation, it is easily possible that the received signal strength will fall off faster than predicted by a naive application of the inverse square law. Put another way, the inverse square law assumes that the transmitter and receiver antennas are in line of sight of each other, assuming "rabbit ears" on the receiver implies that the transmitting antenna needs to be above 400 feet for a 25 mile path and 1600 feet for a 50 mile path.
All they know is that it will not transcode any faster than their X86 and costs as much as a house.
Hmmmm, I'd love to be able to buy a house like the one I'm in for what the low-end Z-series runs... Then again, I remember when moderate size mini-computers (e.g. CDC-1700) cost as much as a really nice house.
IIRC, it was Solaris 2.5.1. Since porting Solaris at that time meant porting Sun's compilers, there was a version of Workshop ported for the PowerPC (which was mentioned in Version 4.2 of the compiler suite).
One of the differences between simplistic models of electrical circuits and real circuits is the nature of "noise". Simplistic models assume gaussian noise, real cicuits usually have a 1/F component as well as the gaussian component. One of the best descriptions of 1/F noise is in Horowitz and Hill's "The Art of Electronics".
A huge point is completely missing: all of the houses were appraised at the values the mortgages were offered. These appraisals were done at market value and were accurate - if you can sell your house for $500,000 today, then it should be appraised at $500,000 today.
Uh no. The fact that a house sold for $500,000 does not mean it is worth $500,000 to another buyer. The whole point of appraising for loan qualification was to assure the lender had a good chance of getting their money back in case of a loan default. What happened was that appraisers were generally pressured into approving sale prices if they wanted business from the real-estate agents.
My take is that there were too many people involved in the process that were making money without any long term responsibility. Things might have been different if say 50% of the mortgage brokers commisions were based on loan payments.
The other big problem was that there was too much leverage in a speculative market - which is exactly what led to the 1929 stock market crash - and that speculation was driven by the Fed maintaining low interest rates.
for instance, most solar power plants on earth seem to use solar thermal energy based on Concentrating Solar Power (CSP) systems like parabolic troughs or solar power towers rather than PV cells. would solar thermal energy not be as efficient in space? how would the lack of atmosphere affect these applications? would it allow for better thermal insulation, or would the cold temperatures in space drain the heat transfer fluid of its stored energy?
Look up some Bonestell paintings from the 1950's - the satellites are shown to be using parabolic troughs for collecting thermal energy from concentrated sunlight.
As to why PV's are favored for space - number 1 guess would be weight as efficiency isn't as important as weight. Second, PV's can be scaled to smaller sizes than solar thermal. Thirdly, getting rid of waste heat isn't as easy in space as on earth (you need large radiating surfaces protected from sunlight.
I probably should do some research before posting - but, hey, this is Slashdot....
That sounds very much in line with the repression of free speech typical of the Wilson administration during the period that the US was involved in WW1. Didn't realize just how bad things were unitl reading Barrie's book on the Great Influenza (which he describes evidence as originating in western Kansas).
I had assumed from the article title that it was about C-14 dating, but TFS wasn't misleading for a change. One of the problems in using C13/C12 ratios is that there are many processes that will enrich or deplete the amount of C13.
High bandwidth lines are expensive, very expensive. Almost no one could afford one for web browsing and email. So an ISP pays for that expensive line and then shares it among hundreds or thousands of people, each paying very much less than the cost what the high bandwidth line actually costs. For this to work, people must be willing to share nicely. Too many are not sharing nicely having some rediculous notion that they are actually paying for the bandwidth available to them rather than a share of the bandwidth.
What you're describing has been the electric utility model for the last 125 or so years. If the electric utitilities provisioned their generation, transmission and distribution capacity to support simultaneous peak capacity of all their customers, electric rates would be several times higher than they are now.
My mother-in-law was talking about some of the activities at her retirement community and mentioned a talk given by a fellow named Jay Forrester. The name sounded familiar, google'd it, and one the first entires mentioned magnetic core, SAGE... No wonder the name sounded familiar.
A LOT of what we take for granted wrt computers was originally developed for SAGE.
What's worse is TFS used "Air Traffic Control system" when TFA was almost entirely about the flight planning system component of ATC.
IMHO, the real problem with updating ATC is that the original ATC system was designed by veterans of SAGE (Semi-Automatic Ground Environment) and thus had a really good idea of what would or would not work. Unfortunately, most of the SAGE veterans are either retired or dead and the only conceivable training program since then would have been the SDI program.
I'd wonder if the problem with Flash has more to do with the variations of the Linux libraries than anything else. Flash works reasonably well on Solaris (both Sparc and x86), which has a much more consistent set of libraries than Linux. On the other hand, I've noted that Flash works better with FireFox 2.0+ than with Mozilla - the latest Slashdot code for non-logged in users will consistently crash Mozilla 1.7 on Solaris x86.
The reason that Flash exists for Solaris is that Sun paid Adobe to support Flash on Solaris and I'd expect that a good amount of the code for Solaris is common with the Linux port.
.. you know, t1000's running around, enslaving humanity. That sort of apocalypse.
This I gotta see, a bunch of 1U UltraSparc T1 servers moving by themselves and ordering people around. Sun's been tooting their horn alot about these systems, but I didn't realize they went that far...
Here is an interesting idea: Don't break the fucking law.
I hope you intended that to apply to Google as well - trespassing is breaking the law.
It might take a shitload of well deserved invasion of privacy lawsuits against Google for them to get their act together and do the Streetview correctly. Whoever planned the picture taking for Streetview obviously had little experience with the laws relating to photography - wonder if anyone there ever heard of a "model release".

Our Earth's surface is overwhelmingly shaped by biology
In addition to the carbon cycle, the large quantities of oxygen in the atmosphere affect what kind of rocks can exist on the surface.
The other reason that Venus and Earth have substantial atmospheres is that the gravitational fields for Earth and Venus are stronger than for Mars (or Mercury). The result is the escape velocity is much higher and atoms are much less likely to escape Earth's gravity than Mars' gravity.

Admittedly, nearly half the "content" itself could fall under the category of "rot" even when it was new, but that's for another thread...
Just "half"??????
Methinks that the "rot" fraction can be much higher than 50% - though the best groups do manage a decent signal to noise ratio.
Isn't that rebutted by basic physics? Both signals follow the simple inverse square law. A TV signal 50miles from the tower is 1/4 the signal strength of the signal 25miles, while a device 50m from a set is 1/25 the interference of a device 10m from a set.
