    Oh, well we can switch to a hydrogen based economy! Wrong again, can't make hydrogen without oil. Can't make fancy electric cars without a current reserve of oil.

    Actually, it's just more economical at the moment to make hydrogen from oil and other hydrocarbons; it's trivial (if inefficient and expensive) to use nuclear power to do it directly from seawater. However, more to your original point, hydrogen isn't feedstock for fertilizers or pesticides. Hydrogen isn't as useful as oil.

    I'm much more interested in how you came up with a food crisis. North and South America already produce way more food than is necessary, with options to increase production through farming more land or (in the case of South America) improving farming technology.

    Well, two easy scenarios:
    (a) Fertilizer and pesticides largely come from petroleum products. American farm production techniques rely heavily on these.
    (b) It doesn't matter how much food you grow, if you can't transport it to consumers.

  11. Re:Which oil peak are we on? Deja vu! on Has World Oil Production Passed Its Peak? · · Score: 2, Informative
    In 1994, the U.S. Geological Survey raised the estimate to 2,400 billion barrels, and their most recent estimate (2000) was of a 3,000-billion-barrel endowment.

    True. However, the USGS is notorious in peak oil circles for having continued to raise estimates of ultimate recoverables (IE, total production possible over human history) in the continental US, even after domestic production had reached and passed the predicted Hubbert Peak (IE, the halfway mark). The USGS 1972 predicted US-48-UR was a value between 2 and 10 times the value currently accepted. (Hubbard, by contrast, was about 10-30% low... from a range of 15 years pre-peak.) And, if you examine the weasel words in their footnotes, you'll see the USGS and similar agencies effectively admit to fixing their supply predictions to equal the value for predicted demand. We're at the absolute brink of Peak Oil. It would also provide a plausible secondary motivation for the Iranian nuclear program, and explain why they are so adamant about pursuing the atom despite having one of the world's largest oil reserves: they also think that Peak Oil is at hand.

    If world oil consumption continues to increase at an average rate of 1.4 percent a year, and no further resources are discovered, the world's oil supply will not be exhausted until the year 2056.

    This, however, assumes that oil production can remain steady, and that those reseve estimates are accurate. The premise of the Hubbert peak is that production rates will begin dropping at increasing rates, due to increasing difficulty in extraction.

    I don't have time to address the problems with each of your silver linings, but looking at a few Peak Oil sites and a quick search for "Energy Profit Ratio" should leave many people skeptical about them.

    Which, in Realpolitik terms, might well justify the invasion of Iraq completely, aside from the stupidity how the invasion was executed (IE, without detailed post-invasion planning or comrehensive allied support). And, no, I am NOT a fan of Bush or the Iraq war... largely because of the aforementioned stupidity in execution.

  13. Like all such tools, security depends on usage on UK Government Wants a Backdoor Into Windows · · Score: 2, Interesting
    If someone gets a hold of your whole computer, they can read files. If someone hacks your system, they can read your files.

    Having needed to break into someone's system to recover encrypted files, I can say it's not that simple.

    Windows NTFS encryption is certificate based. For installs done by anyone not a professional paranoid, the user has access to the file recovery certificate, and the domain administrator may have access to a file recovery certificate valid domain-wide. To use a certificate stored on the hard drive, you MUST have the password to that certificate... which is NOT changed when you force-change an account password.

    So, yes, you can hack a machine, install a trojan, and read the users files when they login next. But, until the user logs in (which, yeah, is usually a short wait) and starts the trojan running under their user ID and password before your trojan can decrypt the files to examine/copy them. Alternately, you can get a dump of the encrypted password files, and try a brute force crack. But if the password used on the account (and, ergo, certificate) is, say, 12 random printable characters... dude, you are so SCREWED.

    Fortunately, the time I needed to break in for someone, the password was "only" nine random characters. I used a boot disk to dump the password file. Then, we wandered over to the operator for the school 128-processor Linux cluster with a case of good beer at 3:30 on Friday, explained the problem, and he agreed it would be OK this once to "not notice" the copy of the cracker program that would be blatantly running over the weekend in violation of several rules. We left, "not noticing" the case we were leaving behind. At 9AM Monday morning, I checked my email, and my batch job had left the user password sitting in my inbox.

    If it had been a 12 random printable character password, we'd still be waiting for the rest of our lives. And, for the professionally paranoid, I understand it's possible to use a non-default certificate (with potentially a different password) for encrypting files... where the decryption certificate need not be on the machine.

    Afterwards, I gently explained to the user that EFS should generally be reserved for situations where you consider the data's loss preferable to its disclosure.

    Any good scientist will tell you that science cannot disprove the existence of God or gods no matter what you discover.

    True. However, it can disprove (to forensic evidentiary standards sufficient to withstand a court of law) specific items of religious doctrine; EG, that the sun goes around the earth. If your doctrine also claims that the religious leaders can never be wrong, and they've been claiming this for 1600 years, then you have a Problem with science if it provides heliocentric evidence.

    Similarly, if your religion insists that God created and populated the world in six days, and considered it finished at that point, you'll have Problems with discoveries suggesting that he's still tweaking at the designs on the various forms of life he created.

    Science can't prove the non-existance of God(s). However, it can sometimes prove individual articles of faith to be wrong. Which leaves religion in general safe, but many specific creeds more than a little antsy in the crosshairs.
