  5. Re:Those helpful links on Quantum Coherence Found Fueling Photosynthesis · · Score: 1

    That phrase makes sense when talking about more general things, but not well defined concepts of a theory. Quantum entanglement is a mathematical construction, and it was already proved that it doesn't transmit information. If Nature doesn't work the way our theories say it works* and teleportation is possible, it will be due to another phenomenum that can't be modeled as quantum entanglement.

    By the way, quantum tunneling doesn't lead to flash memory either. You should check how it is made, it is quite more mundane than that.

    * Take that for granted, the "If" was just for emphasis. Nature doesn't work the way our theories say.

    You did claim it would come through quantum entanglement (what some people call quantum teleportation). It is impossible to transmit even classical information through quantum entanglement, and that was proven for sure already.

  10. Re:dont you mean 'union made goods'? on Voyager 1 Exits Our Solar System · · Score: 1

    I'd put it on the "fired every unionised worker, and replaced them with good workers" bin. That situation is singular because it was a smal company, and you didn't have enough money to get out of the hole by yourself, so you sold it to somebody who could.

    The fact that it is a tragedy didn't come unoticed, but tragedy is what happens when people make bad decisions, and it seems impossible to make people stop making bad decisions. Also, I'd like to point that this "vote for unionising" (that I stil didn't understand why it has any meaning) probably only happened because the government created more laws than what are needed to protect unions, making (as I understand it) your company slave of the union after the vote passed.

    So, I'd also fill it under "government oblies you to hire unionised workers".

  11. Re:dont you mean 'union made goods'? on Voyager 1 Exits Our Solar System · · Score: 1

    Doesn't work this way.

    1 - You hire people not from the union (without a clause forbiding them of joining). Unionised people go on strike. You let those go, and hire more people not from the union.

    There are a few ways things may proceed from then:

    1 - Good workers want to join the union. That is because both the union is good for them, and employers aren't. You are out of luck, since you won't replace those unionised workers with good ones.

    2 - There are plenty of good workers out of the union. That is because no union is any good (a temporary situation) or because employers are not very exploitative. You are in good luck, you'll be able to replace those unionised workers with good ones.

    Of course, all that can only happen when the government doesn't get in the way and mandates that you hire unionised people (or that only unionised people have the right ro work on a market).

  17. Re:Why? on AMD Downgrades Bulldozer Transistor Count By 800 Million · · Score: 4, Insightful

    "I suspect that transistor count means different things to different people."

    No, it means nearly nothing to anybody. The closest one I've seen is another answer to this thread linking it to cache sizes, but even then, people measure caches on bytes, not transistors.

    Buyers want software performance, measured by benchmarks, cache size + instruction throughput, or any other functional metric. Engineers care more about hight level units, except where they optimize deeper, fabs care about die area. Nobody cares about how many times a poly line crosses over a crystaline line.

    By the way, that is probably the reason such a huge mistake in the number could be made. Nobody cared.

    In theory you can not expect to break 1024 bits RSA or 256 bits AES in a lifetime.

    In theory you can forge checksums to defeat any security mechanism that depends just on software running on a computer where you are root.

    Do you see the diference there? You are not calling it improbable based on a formal statistics analysis.

    Normaly, in security, when one says "In theory ... it is possible, but I don't think it is probable" that one is shortly rewarded with data showing that he is wrong.

    On this specific case, you are forgetting to take into account that the algorithm (and software) is open. Also, you are forgetting to take automation into account (there is a computer available for the attacker, after all).

    You mean "what problems this proposed thing proposes to solve". Currently, it solves none of them. In fact, it just creates a new problem because the loger now is so complex it should log its actions.

    But I mostly agree with you. Distros should experiment new things, and Fedora is the right place for RedHat do that. It is just that this one experiment is dumb, people aready tried that more times than we care to count, and everybody already knows how it ends. And everybody is being that vocal because we fear that we are forced to take part on the experiment, and that it will last for decades, like already happened on other times.

    Databases don't magicaly add tamper resistence. Neither does a checksum algorithm.

    For a tamper resistent log you'll need to send the logs to another device, and make that device as tamper resistent as you can. A printer is great for that, but I don't think you'd want all that paper around, so most people just use another computer.
