    I've never heard of the Pan Spermia theory, but when you paraphrased what it means "life is spread infectiously though out space", then what about radiation? Cosmic rays and the 3k background are bound to disrupt celluar actions (assuming they are cells). Also, space is quite harsh to adapt to. No pressure, extreme tematures, and little food, unless these creatures are able to turn radiation into food. I just don't get how a small organism can stand a flash fire (eg. in space outside of Earth, if you were facing the sun with no suit on, your face would boil and your back would crystallize). Viruses do seem to be an interesting variant, but they require a host to reproduce, at least to our knowledge. Still, this theory does intrigue me... Josh Crawley

    You all question water to survive. Since I want to further my understanding, what sort of liquid do you think can replace H2O ? I do see a few things that water can do/properties it has.

    1: H2O is quite light. It's only 18g/mol. There's no other combination _I_ can think of that would be as light, as we humans are made up of a lot of water.

    2: H2O is slightly polar, so it 'sticks' to certain structures a little more. Oil would be an interesting substitute to water, but oil is large polimer chains. Too hard to create. However Ions would disrupt other chemicals. Also, Ions require water to have charge.

    3: Most of all biological elements are within the top 10 elements on the peridic chart. The reason these are used is because nuclear fusion within the sun allows these to be made with much greater abundance. This reason also coves why no Earthen creatures use silicon instead of carbon.

    4: If you can accept the above examples of why water is better than other mostly inert transfer chemicals, then tempature also comes into play. I know of no animals that use solid or gaseous blood. All use liquid of some type, just because diffusion (or in water, osmosis) is easier to transport chemicals. The tempature of water being a liquid is between 255K and 310K , so most planets are eliminated just because of the tempature needs strict control.

    A simple question about life in general: What grows faster, plants in the rainfores or plants on Antartica?

    This sounds like wishful thinking and all, but who actually believes anything can live in the environs mentioned in the story?

    The article:

    ""Oceans might be common and diverse in our solar system and in other solar systems, according to David Stevenson of Caltech, who regards the old notion of a narrow "habitable zone" (Venus too hot, Mars too cold, Earth just right) for liquid water oceans as erroneous.

    Stevenson spoke earlier this week in San Francisco at a meeting of the American Geophysical Union at a session intended to bring together two scientific communities that scrutinize very different realms--the planets and the seafloor on Earth.

    The connection? Observations from the bottom of the ocean show that microbes thrive both in near-freezing seawater and in near-boiling effusions from thermal vents. These conditions might turn up in many other planetary environments.

    For example, the Galileo spacecraft has provided evidence for watery oceans on three of Jupiter's moons-Callisto, Ganymede, and Europa. Subsurface oceans could be kept liquid by warmth from tidal forces (Jove wringing its satellites) or from radioactivity. Torrance Johnson of JPL, also speaking that the meeting, said that Europa's ocean might be 75-150 km thick and could thus harbor twice the water in Earth's oceans.

    Stevenson added that observations also hint at oceans on Titan, Triton, and Pluto. In the case of Titan (soon to get the Galileo treatment when the Cassini spacecraft reaches Saturn in 2004) an ocean would be a mixture of water and ammonia (acting as antifreeze). Under some circumstances water might even be found inside Uranus and Neptune.""

    Europa does have very likely evidence of a liquid ocean, but the article then uses that to 'assume' of living creatures there (bac). How can there be? Complex nucleotides and a slurry of other complex chemicals are required for 'life' to occur. Another problem is energy entering/leaving the system. The Earth is quite close to the sun, but europa can rely on nearly 0 energy from the sun (at least as useful radiation). Tidal energy is energy none the less, but it's too limited, even coming from Jupiter.

    Energy, yes but useful, no.

    =="(almost) anything that you can see in these photos you can see in person. If people from other countries are seeing it, they could see it in person for the price of a plane ticket and a good excuse to get a visa."

    Other than many military installations which are surrounded with razor wire fencing, this is true. I'm mainly worried about those installations.

    =="I've heard other people raise this argument before; "doesn't this help terrorists/rogue states"? Think about it, genius."

    First of all, I am 'thinking about it'. How does commercial sat pictures _help_ us? I cannot come up with at least one convincing answer.

    =="Do you need an aerial photo to aim an ICBM at NYC? Did the terrorists need to research the area around Manhattan to figure out that the WTC is located there, and they should fly the plane in that general direction? Honestly, what the hell can you do with this?"

    First you have to see terrorism in the terrorist eyes. If I remember correctly, our local television news programs have 'exposes' that detail the lack of military awareness of chemical factories. In our area, there is a military surplus of many types of nerve agents. The news mentioned what the facility was called. Now if some rich terrorists were to look at a map and determine where this was, they could buy a sat map and know the outer schematics of this plant.

    Also, be aware that some military installations are NOT on maps. the only way to see it is to get past the guards with nice SMG's (yes, the last time we passed through, they were carrying that type).

    =="Also, I'd have trouble believing that the Chinese gov't is not aware that the US has the ability to peep at them with about 50 different satellites. I don't think they are suddenly going to become aware because Joe User posts pics online."

    Maybe I didn't explain what I considered that bas scenario. The US knows about China's (fill in the blank), however the US hides that knowledge from us for certain reasons. There is NO need to know about a nuclear reactor at coords x,y or other such stuff. This type of data should be seen as need to know only. All we should care about is if the military is doing thier job.

    =="As for pictures of US military installations, what is there to see?"

    Like I said above, there are some installations that positions are itself marked as a rating _under_ classified but still not released to the public. Pictures of these places are nothing but deterimental

    =="Anything that they don't want you to see is hidden underground, and the government restricts private remote-imaging firms from releasing data less than 24 hours old. So if you're Osama Bin Laden, you might be able to get a pic of the B2 that just bombed your ass taking off, although about a day late."

    So you told me something I didn't know. I wasn't aware that such a law exists.

    I may be much for technology, but this kind of thing comprimises US national security. I live here in the country (aka, not city) so things like airplanes crashing in our house is'nt a problem. This sub-point is that I'm safe from extra-government actions.

    What it comes down to is; if we can buy pictures of 64 cm= 1 pixel, so can terrorists and enemy countries. The US military made this type of device in the Cold War so they could SPY on other countries for intelligence (however mainly USSR at the time). Now, they're used in large intelligence missions over enemy territory so that OUR soldiers don't get killed due to lack of mapping.

    There is a good basis for the US military to have this technology, but what are the pluses for non-military to have this? Other than the sake of knowing, not any. They aren't valid survey techniques, you pay surveyors that. Home camera's make good security systems, sat cams don't.

    The negative's come at a distinct disadvantage. Say a US civillian is interested in a Chinese nuclear power reactor and pays for sat scans. Then they post it online, which I believe this has been done (can't remember site). If the Chinese gov't find about this, don't you think that they would be slightly miffed off at the US? Or how about taking pictures of US military installations? Those are dangerous to the saftey of US citizens, Military and non-military.

But did you also know that the MPAA gets liscensing fees for DVD tech from about $1,000,000. There's a reason China created the standard of SVCD.

  16. Is the FBI that dumb?? on McAfee Will Ignore FBI Spyware · · Score: 2, Interesting

    Instead of believing in to the hype that Slashdot has come to like, let's look at the situation(s) more closely. My main questions spawn from ponderance of the WHOLE situation. These questions I plan to adress.

    1:Why did MCafee allow this trojan?
    2:What is the FBI's purpose in creating this tool?
    3:Why did the FBI tell?
    4:Who is this tool targeted at(main classes of criminals)?
    5:How will other anti-virus companies look at the FBI's choice?

    Well, lets consider the targets first. I see the most common groups targeted at are drug dealers and computer _criminals_. It's safe to say that the Computer criminals probably will not be caught in a trap like this. The FBI's main tool is believed to be a windows executible however, don't make rash belifs that the FBI hasn't considered a *nix tool yet.

    The main mode of transport is that of a binary segment sent over email. Since Outlook is the most popular form of email client, Outlook buffer hacks that 'autorun' binary code are the best transport. Next off, who said that the FBI would be sending data back through the Internet or do any dialing? If I wrote a tool like that, I'd store data (keystrokes, logins/passwds, 'certain sites') in a secure place of the computer. I'd aim for the segment after the bootsector code. There's plenty of space for a few KB of the 'best info'. The FBI would raid the machine anyways, so sending back data is useless (trace of tcp/udp streams would be evident).

    However, I question why the FBI even told here. Thier purpose is to catch intrastate criminals and investigate bad political dealings. I'm questioning if the FBI even has this technology. I'm much more scared of a hardware dongle that has 5 megs of storage capibility. Those types of entering have been cleared by the courts, providing the correct documents have been presented. Malware is going to be caught, unless the FBI destroys the data before the criminal sends it away elsewhere.

    The last fields of questions deal with the AV companies themselves. Why exactly did MCafee do such a thing? Perhaps they have no choice. There is such a law called Obstruction of Justice. If the AV companies do not allow some sort of loophole, they could be tried in a court of law. Most of you Slashdotters would say "So What", but this type of court battle would lead to either horrendous losses to the company, and eventually having to put the anti-FBI code in, or the destruction of the company. However all is not lost. There is more AV companies outside the US. They WILL defend thier rights to no FBI code in thier computers. I mainly count the Russian AV coders to somehow get the code and track/kill it.

    Flat out, the FBI will fail only because of public outcry. They will catch a few criminals and will parade around saying how the US is a better place without the 'scum of the Earth' around. However the worst thing people could do is to assume that the FBI is stupid. They have already addressed most of the questions, better than that has slashdot crowd.

    A secondary problem of why I cannot run yast (without going and editing modules out) is the ethernet autoconf. I'm using a mobo that has onboard lan but I have no risers, so I'm using a secondary card. The SuSE autoconf sees the 2'nd card first and applies that driver to the first card. Kernel Panic.

Rebooting and restarting the installer did NOT help. We had to resort back to Yast1 and use the cfdisk and fdisk(on the 2'nd cd).

If Linux manufactuers could create a SEAMLESS install with autodetect Sound/Graphics/Ethernet and start at a nice fuzzy KDE term, then that's the product for them. However it doesn't.
