  1. Re:OT: What is going on here? on JBI's Plastic To Oil Gets Operating Permit · · Score: 1

    It says "Karma: positive". But no idea what this means in detail.
    I think it started after my comment on the probably larger nuclear waste from a large number of small nuclear reactors. I was tagged "flamebait" immediately. No one understood it, and I got mostly flaming replies.
    So this identity is now an outcast of the slashdot community, and I have to start a new one if I want to stay? What a nice system.
    Oh and thanks for rating me down again.

    Oh please, arresting Roman Polanski would not make any more sense than arresting Assange. He went through the sentence that they agreed on, and fled because the judge ignored the deal that was made before in oral form. That is why Switzerland did not extradite him to the US.

    He did not open a bank account using fictitious information. He used his lawyer's address because he did not live in Switzerland yet. And I never heard about him giving a false address to the British courts?

    DOS attacks often work with random faked sender IP adresses, so the DOSed server can not just filter out the computers doing the attack. Wouldn't a filter at the providers for fake sender IPs make DOS attacks nearly impossible?

    (*: If he's innocent, he can go back and defend himself. If he's innocent, he has little reason not to and a big scary reason to do so... namely, to clear his and wikileaks' names.)

    Assange is not hiding. Scotland Yard knows where he is. They are not arresting him because they think that the arrest warrant is not valid.

    He has offered several times to speak with the Swedish authorities. He did before he was leaving Sweden, and when he arrived in London. He has offered to be questioned in a video conference, to sort things out and to clean his name. He just does not take the journey to Sweden at his own costs, for just another questioning.

    And the press does not know where he is.

  8. Re:Is this really bioluminescence? on Gold Nanoparticles Turn Trees Into Streetlights · · Score: 1

    Yes I was exaggerating. But still, the story about streetlight makes this effect much more interesting to everyone than it really is. This fluorescence and energy transfer from the gold nanoparticles to the chlorophyl is an scientifically interesting effect. But it will probably not change your life.
    So many people are doing this to get attention, and I think it is just annoying.

  11. Nevermind. on Lasers Approach Their Ultimate Intensity Limit · · Score: 1

    After actually reading a bit more, well... These papers are about generating positron-electron pairs from the collision of two electron beams, with the electrons being accelerated by laser.
    The long-known theoretical intensity needed for pair generation is 10^28 W/cm^2. From what I just found this has not been achieved yet. In the paper linked in the summary it is stated that a single pair generated will lead to the generation of a lot more pairs: The generated electrons and positrons are accelerated by the electric field of the laser beam, reaching energies high enough to emit more pairs.
    This is about the intensity in a focussed laser beam. In the laser itself you will get problems at much lower intensities.

  13. Re:Data storage density on Why SSDs Won't Replace Hard Drives · · Score: 1

    Of course some controller logic is needed, but it does not have to be that much.
    When you compare current SSDs to my proposed 2600 SDHC cards, you will see a lot of room for improving the data density. It starts with the chip casings, which are already much larger and more thick than an SDHC. By stacking several chips into one small casing you will get a much higher density. Next is the circuit board, which is taking up alot of volume by itself, and normally it is only one board with no more than 2 layers of chips, front and back side.

    Current SSDs just are not optimized for high storage density. It is just not practical, the 2600SDHC cards would cost more than 200 000. But there is so much room for improvement that spinning disks clearly would not have a density advantage, if SSDs were trying to compete in this area.

  14. Data storage density on Why SSDs Won't Replace Hard Drives · · Score: 1
    From the article:

    Flash will never have the price/density advantage of hard drives, however.

    A MicroSD card has a volume of less than 0,115cm^3, with 32GB capacity currently availlable. A 3 1/2 " HD is 300cm^3. Filling the HD volume with MicroSD cards you will get a capacity of 83TB. HDs are 2TB maximum, so flash memory already has a clear density advantage.

  15. Re:Nuclear waste on The Rise of Small Nuclear Plants · · Score: 1

    Seems that I have to post the same reply to everyone. Breeding reactors only takes care of the uranium and other very heavy atoms. It does not do anything about the fision products, which are lighter radioactives. And it does not do anything about the material that the reactor is made of. This also becomes radioactive because of the neutron radiation.

    The reactors can reuse Uranium and Plutonium, but not the fission products and all the material that becomes radioactive after being exposed to the neutron radiation.

  17. Nuclear waste on The Rise of Small Nuclear Plants · · Score: 0, Flamebait

    The big problem with nuclear power is radioactive waste. There is no way to recycle it, and no matter where you put there is always the risk that it will show up in drinking water or somewhere else in the environment in the long run. I guess that all these small reactors will produce a lot more waste.

    There has been a similar european project named "Hopper". It was planned as a first stage for a launch to orbit.

    With a smaller aperture you get a larger depth of field, meaning that a larger distance range appears sharp in the image. If your photos are of a scene with certain depth this might be the reason. But also if your focus wasn't set to th right range a smaller aperture would increase sharpness.

  23. Re:Timeline on What Is Time? One Researcher Shares His Exploration · · Score: 1

    While this effect of traveling into the future is often described in polular science, it was mentioned in one of my theoretical physics lessons that this is just not possible. Time deviation in special relativity theory is a result of the Lorentz transformation. Lorentz transformation is just a way to consider that no signal can travel faster than light. Consider someone is moving away from you at a speed close to speed of light. Now this guy is raising his hand twice. In his timeframe it is just 3 seconds between raising his arm first and again. But if you watch him, and could somehow see if he raises his hand, it is a much longer time. You see him raise his hand first when he is in a certain position. When he raises his hand again he has moved hundreds of thousands kilometers away. The light needs several seconds more to reach you from the place where he is now. This effect is what is expressed by time dillation. If someone is moving away on a spaceship, he will experience time dillation. But when he is moving back, the effect is reverted. If he sends two signals with a certain time delay between both signals, these signals will arive on earth with a shorter delay between them. The ship is closer when sending the second signal, so the second signal takes less time to arrive on earth. Time travel is just a misinterpretation, sorry.

  24. Interesting, but not for actual quantum computing on Caltech Scientists Film Photons With Electrons · · Score: 3, Informative

    As I understand the article, this technology works as follows: a short laser pulse excites the electrons of a sample material. After a short delay t, a short electron pulse hits the sample. The diffraction of the electron pulse is used to generate a picture of the electronic states in the sample at the time t after the excitation by the laser pulse. This is repeated several times, with different delays t. By combining these images, they can see how the electronic states develop over time. It is a combination of pump probe spectroscopy and electron microscopy, very interesting that this is possible. However the state of the electrons excited by the laser is destroyed every time an electron pulse hits the sample. You can only see the time development of electronic states by repeating the complete experiment, which is not what you want for a quantum computer. I think this is a fundamental principle of quantum mechanics described by Heisenberg's uncertainty equation. However this is not my field, and I don't know much about the details of quantum computing. Maybe this technology can help to understand what happens in a quantum computer though.
