  1. Re:Global Warming? on Mountain Moisture Melting · · Score: 1
    Well, they do say that this ice formed during "an extremely wet period" 11,000 years ago. This implies that before then Africa was drier, although does not refer to temperature.

    Of course, that time is also rather close to the end of the last Ice Age. They don't mention if they know if there was an ice cap on the mountain during the Ice Age, nor if there was an ice cap before the Ice Age.

    So... What is the paleoclimate pattern of Africa and what should be done about the climate?

  4. Earthly design of Venus genetic material on Possible Signs of Life Detected On Venus · · Score: 1
    Well, I did observe years ago that if we want to terraform Venus it would be interesting to make a hydrogen-bladder flying plant. Let it float at an altitude which is "cool enough" to live at and it would provide shade to the planet. Its real purpose, however, would be to convert carbon dioxide to organic matter, making the atmosphere thinner and locking carbon in material on the surface of the planet. As plants die and fall, the organic material would head toward the surface. Water would also be present in the plants.

    It is OK if the plants are flammable -- they'll emit oxygen and if they catch fire they'll fall where they ultimately are wanted. I don't know if they could evolve to remain floating in an Earth-like atmosphere, as it would be awkward to live with flammable things floating through the neighborhood. And if a stable ecosystem arose which did not conclude in a human-inhabitable planet then we would be no worse off than now, with all our eggs still in the Earth basket.

    There already are many water-floating plants with bladders. There are plants which extract nutrients from air. There are bacteria and other life which create hydrogen-based gases. Combining these starting points is undoubtedly not simple...if it can be done. But if an environmental impact statement is required, that would surely be the hardest part.

  6. Re:how does newer == less secure? on Windows vs Linux On Security · · Score: 1
    Linux, which is even newer than Windows and is not controlled by a single commercial entity, can be expected to have even more vulnerabilities than Windows.
    Notice the article separates "Unix" from "Linux" but lumps "Windows" as one entity. As if Linux did not gain from the design and experience of Unix, MULTICS...although DOS didn't until it began acquiring Unix accessories. I wonder if he's including the "X11 Window System" in the age tally with "Windows". Somehow I'm sure the version of Windows which is just an MS-DOS GUI would be separated from "Windows" if he seriously began discussing security. Of course, we also saw no mention of "VMS" and "Windows". Is there an expert in the press room?

    In DOS/Windows, deleting anything on disk is not a bug. It's a required feature. Thus there is nothing to fix...other than fixing the buffer-overflow which was used instead of just directly making the correct system call to alter the disk.

    • If some of those microbes are in Earth's atmosphere, does that mean we're being Venusformed?
    • What's "environmental" about someone who wants to force plants to be the way that person saw them in childhood rather than letting them change as they naturally do? A different word is needed for historically-ignorant complainers.
    • We'll soon hear complaints about the Sun swelling up and engulfing Venus in a few billion years. Surely something must be done to protect Venusians.

    "These bacteria might be a genetically-enhanced version of the thermophiles which are known to survive in extreme temperatures."

    The phrase "genetically enhanced" has become an abbreviation of "genes altered through chemical manipulation". All evolution is natural genetic enhancement...even if done selectively by plant breeders who, for example, create large juicy ears of corn from a plant which produced small ears just a short time earlier (and I have no idea how much corn had been altered by pre-Columbus breeders).

  12. Rocket Fuel on Surprising Science Demonstrations? · · Score: 1
    Simpler example: rocket fuel.
    Liquid oxygen and alcohol.

    A NASA presentation used a small sponge in a flat dish. Pour alcohol on the sponge and ignite it, producing an almost invisible small flame (you already know you can add chemicals to make the flame visible, but it is not necessary). Pour a small amount of liquid oxygen (far away) in something like a long-handled ladle (small cup with long handle -- metal probably needed so it won't be too fragile). Pour the liquid oxygen in the dish.

    This should be done in a high-ceilinged gymnasium so the flame might not reach the ceiling. Ensure that there is not a fire alarm or sprinkler which will be set off by the demonstration. Test first. Might be safer outdoors...if it won't alarm neighbors and if you have alerted police and fire departments to ignore calls from neighbors and passerby.

    Actually, this entire issue is illegal.

    1. Discussing what is wrong with the DMCA could cause the DMCA to be revoked.
    2. Revoking the DMCA would remove its protection of protection systems.
    3. The DMCA is a protection system of protection systems.
    4. The DMCA makes breaking protection systems illegal.
    5. Attempting to break the DMCA violates the DMCA.
    6. Attempting to have anyone alter this law is a violation of this law.

    Therefore I have nothing but good things to say about the DMCA: It has many wonderfully organized words, the authors are very intelligent, and the Federal Register is a well-organized piece of literature.

    It doesn't sound like fantasy, that is exactly the present DVD situation. DVDs already use a format which non-DVD players can not read, because the data is encoded in a secret fashion. You can not write DVDs nor build a DVD reader without using this secret code. The DVD rights owners will not allow everybody to use DVDs -- they require that the code be kept secret.

    Try replacing "FSF" for "Time Warner" in your posting, as if the FSF purchased a DVD license the FSF would require that its DVD program be public. The DMCA merely protects the DVD encoding, and is why the DVD-decoding formula is already a legal issue.

    The usual meteor is a few millimeters, but its plasma plume is much larger. You can see an aircraft strobe at 30,000 feet (that's only 6 miles) but a meteor is much further and has to be brighter than that.

    The AMS has a FAQ on the subject which includes brightness info. It also points out that nickel tends to produce the green color.

    Also, there probably is a correlation between your bus-waiting guy and these other sightings. If you're in the northern hemisphere...there is more darkness right now than a few weeks ago. Easier to see meteors.
