    I always was under the impression that the drop-height should be around 80cm onto concrete floor, without damage. Good luck in performing the tests with "rugged ipods" and re-certifying them. Also i would imagine that a certain degree of maintainability would be required. And checking humidity/temperature/dirt/continuous/vibration stability will also be necessary. The qusetion "how many of these fail after being enclosed in the freight space of an transport plane, beein cooled down, left for a day in +70 degrees in the inside of an box in the sun, dropped when unpacking" is a question which should be answered.

    We will see if "cutting the costs" by "of the shelf HW (and SW)", which was not designed to make such certifications easy will be cheap after upgrading it with these certifications.

    I refer you to the following comment. It may point you to the right direction (namely that all the time that a researcher says "non dissipative transport", there is a risk that all which will be understood about his great research will be "something like a room temperature SC"):

    And about people doing research and having insight: I listen very careful if people from other areas of solid state physics talk to me about my subject - they may tell you how they perceive it. Ideally They should be close enough to understand what you are doing, but far enough to be not competitors.

    I got that it is about a new method of producing it. The summary was simple enough to get it. I disagree completely with the direction of research, i just wondered about that off all the wonderful things you could think of to do with such a special material as graphene, room temperature SCs are mentioned that prominently.

    And comment has a little bit strange tone, like i stepped on somebody's feet. Would we make the ability to change something by direct influence to a measure for posting a comment on slashdot, i guess comments on slashdot would be obsolete.

     

  10. Room temperature SC? on Graphene Sheets Get Easier To Manufacture · · Score: 5, Interesting

    A small disclaimer: i am working with low-temperature supercondutors, but i only use them in an application, i am not researching these.

    That said, i state my opinion from somebody who want to build sth out of superconductors: The hunt for a room temperature SC has consumed a lot of attention, money, and research time. It would be better to stop focusing on searching for a RT superconductor, and to stop telling everybody you want to do so. In 90% of the cases other properties of the SC prevent its widespread use. That is, because during the last 20 years cooling technology has made great progress. Nowadays, you can buy "press a button and a few hours later you are at 100mK" systems of the shelf, as well as hand held pulse coolers going down to 5K. For most applications, where superconductors would replace normal condutors, cooling is a big issue with normal conductors already. E.g. high field coils build with normal technolody consume incredible amounts of cooling water, which make cooling the same mass to a lower temperature, but much lower cooling power a very favorable idea. In electronics, air conditioners of computing centers now are already big.

    While i believe that graphene is one of the very promising new materials, i dont see it application as superconductor soon. My suggestion for the community would be not to blow out too much research time of this, but focus on the unique properties of the material. If as a byproduct, it turns out to a good SC, it will take 10-15more years to develop applications using it. Moreover, the continuous fantasy of the room temperature SC has worn off a lot of its glory since the first discoveries of HTSCs. The possible disappointment in funding agencies associated with even mentioning this is a dangerous thing. Otherwise i believe whatever you can with graphene, there is a load of really fascinating new physics to be done. But first telling "hey we are close to a room temperature SC" may take the attention of the referee and when reviewing you results, he may say: "you did not do what you promised" instead of "fascinating new science you did!". That is, because the referee is selected to be matching the field of the project. Would i work on graphene mono layers i would prefer to have a senior 2DEG guy as a referee instead on of the HT brewing alchemists (sorry, this is note meant negative - it just honors the fact that the HTC experimentalists are still out in the dark, because theorists did not yet come up with a conclusive theory...., most experimentalist in the field do great experiments with combining really cool analysis methods with great care and use a systematic way of exploring the parameter space of HTC materials, which is fascinating. I am not patient enough to do that.) .

  11. Denial of Responsibility on How To Suck At Information Security · · Score: 1

    Usually lack of information security goes hand in hand with organizational structures which developed highly formalized ways to shuffle around responsibility. I work in such a structure. The result is that as long as "some measures are taken" after "an incident" it's ok. However, arguing before an incident about problems is seen as "creating additional trouble".

  12. Re:RS-232? Really? on Seagate Hard Drive Fiasco Grows · · Score: 1

    You would wonder where you can find RS232. The fact that RS232 is still one of the standard ports available on nearly ALL microcontrollers makes it quite popular. Still a lot of scientific instruments, even upgraded versions of older instruments, contain RS232 (mostly to be 100% compatible.....) Although for something like HDs i would not have expected it.

    Normally "New Scientist" reports about work already published in other Journals, and we should keep it that way. I am working on something completely different, but also busy with noise (in the quantum limit) and i can say that even if the experiments i do are extremely simple - i would say trivial - in comparison to this absolutely amazing interferometer, there are a *lot of sources* of spurious noise. Working for one year scratching your head about a specific source of noise is nothing unusual.

  15. Re:Delete it & forget about it on Tricked Into Buying OpenOffice.org? · · Score: 1

    Ok. I am not a lawyer, but essentially everybody can send an invoice to everybody. Normally it is assumed that bad invoices happen as an *accidental error* , in this case it is expected that you actively deny the validity invoice. But with a little bit of luck, you meet a judge which slams them into the gorund when he sees this as betrayal

    So the possibilities are the following as far a i see it.

    0) you pay

    1) you just dont pay
      a) The scammers give up because you are not worth the trouble
      b) the scammers send you a Mahnung
          I) you pay
          II) you dont pay
              AThe scammers give up
              BThe scammers go to court
                *You hit a judge with reason, who says "this is not a contract"
                *You hit a judge who believes "this is a contract"

    2) You dont pay and say that you have no intention to pay
      a) The scammer give up
      b) Jump to 1-b-II-B, just with the extension that it may be easier to dipute over the contract,

    So this means that just ignoring it leas with quite some probability to nothing happening, but may lead to bigger cost for you if you go to court. Sending the letters you have to send on the letter paper of a lawyer inceases the chances of the scammers giving up considerably. In general it may be very important to state directly that you dont intend to pay, otherwise the Mahnung is a kind of automatic.

    Well, I am German. In Germany there is an well defined process on how you collect your money.

    2) Mahnung (Informs you that you are late paying)

    3) Goin to court and getting the permission to get a court order, which will be executed by the state

    Just doing nothing can easily end up in 3). I would suggest, if the situation in unclear, to go to a lawyer. My experience pretty much says that in Germany most scammers back off. Usually when people trying to fuck around with you get a nice letter from a lawyer they stop statistically is does not pay off for them.

    The responses to this here where highly predictible, and many af them are quite naive.

    Modern DC-DC converters have excellent Efficiency over a wide dynamic range of loads. This holds true for the small, nice isolating ones which every designer of instruments likes very much, and also for larger ones. No transformers, smaller capacitors, easier redundant designs, easier buffering. In a time when computers are more and more designed to vary their input power according to their load, all these things could provide a savings of energy (and money). Even if this saves only a few percent, the investment will be payed off in a reasonable time.

  22. Good.I never got what "big" lectures are good for. on MIT Moves Away From Massive Lecture Halls · · Score: 1

    Not to say there were not a few lectures i enjoyed, but even seen from afterwards (i visited the last lecture in 1999) i still feel the same about lectures in big halls: They are usually a waste of time

    Let me classify the persons in the room

    1) the Lecturer. If it is a big lecture, it is likely that he got the shortest straw. The students are so many that he doe not see a possibility figure out which student belongs to which the following class, which makes him feel sad at best and revengeful (for beeing there) at worst, instead of working with the students.

    2) sometimes: the assistant for experiments. His role is to be an overqualified (with a phd) replayer of experiments unchanged for decades. He would prefer to be at his own research. Nobody can expect that he contributes, so he doenst even if he may enhance the lecture very much.

    3) The students.

    a) the ones reading the book before the lecture. A small but important group. the best would be to meet them in a tewnty minute session and let them ask questions.

    b) The completely clueless/untalented ones, whose last attempt it is to pass the exam for this lecture, and who are present always therefore, hoping to get a few extra-points for beeing present. They will only feel even worse about beeing clueless because of a)

    c) the rest, who is there for one of the following reasons: Coffee Machine in the basement. Meeting with buddies for the breakfast. Returning Homework. Copying homework. Meeting the cute biologists in the break. Ahem, and yes: looking at which chapter in the the textbook the lecture is currently.

    I belonged usually to class c). I now have my phd and i am currently working as a postdoc. I visited maybe 25% of the suggested lectures, and my attention span is, due to ADS, something like 5 Minutes. I am only moderately talented for what i am doing and my intelligence is in comparison to my peers slightly below average. The best students who started with me where virtually not present in the lectures. And visiting the lectures did not help the untalented ones a little bit. For me, it never made a difference, as for a lot of other people i know.

    What i know is: the closer you work with students, the bigger is your chance to teach them something (not only about science) - and also to give them positive or negative feedback, and parts of your enthusiasm. I feel good about the fact that i manage to bring even a mediocre student trough his maste thesis and that the lab courses in which i supervised small groups of students sometimes motivated the students to continue the subject, or research in general. Talking twenty minutes per week with a single student to discuss where his internship project should be headed is, in my opinion, worth more than putting him in a lecture hall for 4 hours. Even students not keen on theory sometimes are reading theoretical chapters enthusiastically if you make the project in which they work for you "their" project (i started to find a lot of subjects interesting, which i found boring before, when i worked on my masters thesis). Science contains a huge amount of project which just need to be done and for which it is not required to be a genius already or have big knowledge.
