  1. Re:I wanna live forever on FDA Testing Artificial Liver · · Score: 1

    Well if they can "immortalize" liver cells, then why can't they immortalized *all* of my cells?

    We could, but you almost certainly wouldn't like the results. (Well, we most likely could do so theoretically; the ethics board would kill us if we tried.)

    Death of cells via apoptosis, phagocytosis and sometimes even necrosis is a very important part of normal processes in your body. WIthout them you'd be a continuously expanding ball of flesh (assuming you even made it to a stage of embryogenesis that could be called a "ball of flesh")

    Hm, immortal. How is that different from cancerous?

    Cell immortality is orthogonal to the abnormal replication present in cancerous cells. There are lots of cells in your body which are effectively immortal but do not undergo abnormal replication, and are therefore not cancerous. [Obvious examples are your spermatogonia and progenitor cells in your bone marrow.]

    As far as immune cells go, so long as you've avoided including proliferative immune cells, you should be free from graft vs host issues. Growing the hepatocytes from cell lines that have been sorted pretty much guarantees this.

    Debian does not autosubscribe the reporter to the bug. I don't know who made that design choice originally, but it really makes the system a pain in the ass to use. I usually just bypass debian's system altogether unless it's a packaging bug because of this issue.

    The reason why they're not automatically susbcribed is because not everyone wants to know about the process of resolving their bug; they just want to know when it gets fixed. That said, adding the ability to subscribe at submit@ time is on the todo list.

    Actually, I've seen people getting kicked out of dorms for not being PC with a comment. Once you say something that the PC-police thinks is insensitive of gender and/or race, they can overreact. The guy I saw getting kicked out of his dorm made some comment to a girl (he didn't touch her or said anything threatening, but it was in poor taste) and then got kicked out for sexual harassment and threatened to get kicked out of school unless he went to special sensitivity classes.

    Residential Halls are where people live; harassing people in them is never appropriate, and sanctions almost always follow such harassment. Since the nature of sanctions is always a private matter between the judicial committee and the offender, you couldn't possibly have seen a "guy [..] getting kicked out."

    Which university were these anyway?

    Sure, but that's a slightly different problem. It does tell you if no one has gotten it, or if enough people have gotten it to continue on.

    Something you can't give in a huge class.

    It's actually surprising to me the number of students who have problems in lecture and fail to make use of the professor's and/or TA's office hours where large amounts of time are available to address these very issues. So while it's not possible to give in the huge class, almost any professor that I've ever interacted with is willing to spend time in their office hours (and often outside of office hours if necessary) to help students grasp the material.

    I can't see any benefit for a class of 30; you can usually get a little extra time there just by asking a question. That 10% is just a handful of questions there.

    Right, for small classes, it's kind of unecessary, because you can ask questions directly of students and often gauge their understanding by their physical expressions.

    In the end, it's just another tool in the arsenal. Used properly, it's very helpful; used improperly, it's a waste of time.

    After I graduated I heard that they'd put in this system where you had to "rent" this fricking remote control, register it (unique serial number, so they could track you attendance) and use it to input multiple choice answers to questions the prof put on the board. I can only imagine the benefits felt by the students

    Used properly, these things can actually be fairly useful, as they allow a lecturer to get immediate feedback as to whether students have grasped the material being covered in the lecture. They also tell students whether they've grasped the material as well, and also tends to get students to engage more with the material.

    Here at UCR, we sell them, and you register them, though only certain classes (usually ones with > 30 students) use them.

    Player pianos only signal note on and note off with the paper.

    Higher-end player pianos (Ampico, Aeolian, Welte, etc.) control the amplitude at which notes are struck, though no where near as accurately as MIDI (which controls velocity and can even modify the velocity after touch). That's why they have more than 89 holes in the tracker bar.

    That said, all of QRS's rolls that I'm aware of are 88 note, though they often have instructions for how to modify the amplitude printed on the roll, along with lyrics in some cases.

    From my understanding, this would have nearly nill genetic variability. So your pretty much bringing back a species that can't have offspring, seems a bit slack to me.

    Genetic variability is important for withstanding change in the environment, but it is not necessary for producing offspring or survival in a controlled environment.

    Since such animals would (presumably) be found in very controlled environments, you could easily produce offspring. (This sort of thing is done all the time for mice lines in laboratory environments.)

    To survive in the wild, yes. However, to survive in a controlled environment, it's quite possible to have 2 individuals (which can be clones of eachother). This is demonstrated time and time again with mouse lines.

    I would assume anyway, that such a procedure would involve first producing a few heterozygous females (clones would be ok) and then manipulating two eggs to degrade the X chromosome of one, introduce a single Y chromosome, and fusing them, then start the cortical reaction, creating a male embryo. [I'm assuming sex determination in wooly mamoths is the same as in Homo Sapiens; I've never studied them.]

    What in the world does the X11 rendering engine have to do with "useable for normal people" or the "xinitrc"?

    X11, and by extension, the X server, is a layer whose job is to put stuff on screen. That means dealing with the wibbly bits (mice, keyboards, displays, video cards, tablets, pedals, etc.) that cause the stuff on screen to be displayed or interact with the stuff on screen.

    That's not to say there aren't problems with X11 and the various implementations of the X server, but it'd help to at least have studied what's actually going on before attacking the work of those who are actually doing the work.

    If you want to lock your luggage, the way to do it is to purchase yourself a starter pistol.

    By integrity, I mean that the iPhone as a small OS would not be a junk anything-goes resource manager, but a stable runtime environment for which people can develop stable applications.

    A platform whose stability is dependent on the restriction of development to specific code is insanely fragile. It should not be possible for developers to destabilize the platform using the published APIs, as the underlying OS should properly manage its APIs and resources. Furthermore, it's not like code audits are performed on the applications that are in the app store, so these arguments are rather specious.

    Take a look at the weekend effect - basically, when truck traffic goes down, smog goes up. IIRC, diesels emit more NO2 than NO, and (again, IIRC) NO2 reacts such that it reduces smog in a VOC rich environment. (If it's not NO2, it's NO, and I got it backwards.)

    I'm not arguing that it shouldn't be hard to get a wrong cert, or that CAs shouldn't have consequences of issuing wrong ones. My argument is that it's currently not hard to get a falsely issued certificate issued by a CA. All you have to do is be in a position to intercept mail sent from the CA to verify identity. Simple DNS poisoning of whatever dns servers the CA's mailservers are using would be sufficient to do this.

    Furthermore, it's not like you can't get a chained signing key like godady et. al. use if you have enough money to do so. (Or possibly cheaper, get a wildcard certificate.)

How many people who use the internet on a daily basis for banking even understand how certification works and know how to detect that they've been the victim of a MITM attack? How many of those would know how to track down the CA of the MITM to determine who signed it originally?

  20. Re:Unavoidable with devices on Firefox SSL-Certificate Debate Rages On · · Score: 3, Interesting

    The only possible alternative is to do what SSH does: exchange keys on the first connection, and just assume that you're probably on a trusted network the first time you log in. Then you get a security warning if the server's public key changes. Most of the time this is good enough, but when it comes to online banking, I'd rather be sure.

    The right way to handle this sort of thing is to have a real web of trust of people, and then do caching of the fingerprints of the keys. The first part breaks the CA trusted-party monopoly, and the second avoids non-initial untrusted-cert MITM attacks.

    For me at least, the ordering of methods of information transmission that I trust is fairly simple

    1. Keys which I've personally (and physically) verified
    2. Keys which others have verified and I have a trust path with
    3. Keys from CAs which have money on the line guaranteeing their verification
    4. Self-Signed certs
    5. Expired certs
    6. Unencrypted connections

    That sending information to slashdot requires a single click, and sending information to my own https servers requires five seems rather silly; I should definetly be warned, but there's no reason to require me to click to pull up a dialog, click to get the certificate, click to accept, then click to dismiss the dialog. A single message with the certificate information as a warning with a display of what this all means and why it may be problematic is good enough.
