    Linux experience. This is in stark contrast with

  5. Re:The journal world is bizarre on Scientists Gearing Up to Publish Unrestricted Journals · · Score: 3
    Journals do actually do quite a bit of work. You submit a paper to them.

    No they dont, not given the amount of money that they get for free. I happen to know the operation of a leading title in bioinformatics. Apart from the editors and reviewers, it is run by 1 (one) person, the secretary.

    Then they need to decide if they want to publish it, first of all. That takes some expertise to begin with.

    Which is done by the editors and reviewers, who are not paid. Editors (who choose the reviewers, and who under whose auspicies the paper finally is published) do get paid but only a litte, as being an editor is more a prestige thing (and rightly so) than anything else.

    All of this takes effort, and much of it is non-trivial.

    On the contrary; most of it is trivial in the scientifici world . You simply can't compare it to another, say commercial effort.

    Scientists could get together and run their own free journals with quality research in them, but that's that much less time spent doing science.

    Firstly, it seems to have worked out quite well in the physics community. Secondly, ask any department what they'd rather have: the current situtation, or shifting $10,000 from the library to the research budget + free access to all literature in exchange for a bit of work to get/keep the free literature initiative going ... go ahead, I'm waiting :-)

    The big question, indeed, is why the researchers and libraries in Medicin and Biology (and humanities etc.) haven't gotten their act together in the way the physicicts have ... but it's coming.

    Uh, yes, indirectly. Without publications, your stream of grants will soon dry up. Also, as I think Bertrand Rusell has argued, people are not driven by money, but by power (and you can get the latter by having the former, though not necessarily the other way around).

    Without publications, you'll have no standing, so no power.

    BTW, being driven by power does not imply being a total asshole; it's natural because with power you have more freedom. Kindathing.

  9. Re:GM food is not a good idea yet on Golden Rice · · Score: 1
    When it comes to new medicines we insist upon years and years of scientifically conducted trials before allowing them to be used on people, and even then look at the things that crop up years later.

    Here is some news for you: genetically modified foods are subjected to years of very rigorous testing before approval. And actually, they have been used for years and years in the U.S., without even the slightest hint of any adverse effects.

    It's good to have this testing. It's not good to be paranoid. The GMO people have actually far more insight in what they are doing than the traditional breeders. A GMO scientist adds/changes removes one gene (say around 4 kBase of info), from among around 4Gigabase of genome (depending on the species).

    In contrast, a traditional plant breeder just smashes up (using gamma or Xrays), 10-20% (which is a very unpredictable change 5 orders of magnitude larger ) of two genomes, puts them back together, then waits what 'll happen. In most cases, nothing; in some cases, something useful; in a few cases, a dangerous new plant. E.g, a traditionally bred new potato variety was taken off the market, because it produced unaccpetable levelss of some glycoside. Oops, should have tested for that. With the tests in place for GMO, this could not have happened.

    Look: Nature is not benign. The most dangerous substances are biogenic. The most devastating ecological disasters were not caused by man-produced (gmo or traditionally bred) organisms, but by existing wild species that found new niches (for many such introductions, man is of course to blame).

    I could go on and on, but let me just say that sticking your head in the sand is potentially more harmful. Where would we be without antibiotics (which BTW already are produced by GMO's), or non-animal produced insulin (same).

  10. Re:Haven't I seen all this before? on Perl 6 Showcase · · Score: 1
    years ago, there was a great programming language called "Lisp". It had lexical scoping, was both interpreted and compiled ...

    why should Perl succeed where Lisp failed?
    Uhr ... lisp failed? As far as I can see, Lisp (in different forms, including Scheme), is more alive than ever. This includes, by the way, some fancy robotics stuff in the Deep Space 2 mission (but I fear it won't be long before perl is in space too ...)

    It may not be used as widely as other languages, but why is that 'failure' ? Hey, apparently only 0.2% of the world is of Judaist belief. Bit of a failure, that. (What a bollocks).

    Lastly, I do agree with the author that this 'different syntaxes for perl' thing prolly going to fail: for most code, the aim is not just functionality, but readability to others. Inventing your own 'little language' is all nice and well, but things only really start to take of if this 'little language' is spoken by more than person.

    The real problem is that the bad guys may eventually succeed in extracting the tagging DNA from the tagged item (not that this is trivial, currently). Once they have that, they can simply copy it (using PCR, a standard technique in genetics and forensic science; see my other post) into large batches of tagging ink, and use it by themselves to tag more stuff. I guess this technique will be useful for a few more years, but then become too easy to fake.

    storage management via reference count really, REALLY, REALLY sucks.

    I concur.

    I have to assume that CORBA is forcing the use of reference counting here.
    There are two things:
    1) resource management within the client or server
    2) object management.

    For 1), it depends on the language being used (and there are more language bindings for CORBA than for any other technology: Java, SmallTalk, C, C++, Lisp, Cobol, Eiffel, Lisp, Ada, Python, Perl. Try this with DCOM (or it's nom du jour). If you use a garbage-collected language, then there is no reference counting. For other languages, there is.

    For 2), the question is entirely different: CORBA is designed as an Internet-wide, distributed object infrastructure (which in addition is an open standard and language-neutral). As such, it would need robust distributed garbage collection, which is simply an unsolved problem in Comp. Sci. All attempts at this have failed miserably so far. Does the web suck because of unreachable pages or 404 Not found errors? That's exactly the problem.

    If that's so, then CORBA sucks even worse than I thought.

    I really think that the widespread use of genetic engineering can only turn out to be a mistake of
    the worst kind.

    Mmm ... not so clear. First of all, we have been using genetic 'engineering' since time began (think of mate choice) and since the Mesolithicum (think of crop and cattle breeding). Also, so far, no examples of transgenic engineering (transfering
    genes from one species to another) or even invidual directed gene transfer in humans has been shown to be feasible, let alone desirable. Given the reaction towards Dolly the Sheep Cloneage, it seems very likely that any such technique will be forbidden, and I will probably agree. I will, however, vehemently advocate the use of genetic therapy (if they become available) for the 'definitive treatment' of very obvious heriditary diseases (such as metabolic defects (cystic fibrosis etc.). Unfortunately it's not clear-cut when a disorder is a disabling disease, I admit.

    What will knowledge of our genome allow us to do? Firstly it'll be "improving" our children, removing congenital defects and then enhancing their natural characteristics.


    Again, it's not that simple. Your 'improving' has been a possibility ever since we started studying chromosomes; this allowed ever better pre-natal diagnostics, with the obvious possibility of terminating pregnancies for foetuses that might have a more or less severe disability. I am not at all convinced it is morally repugnant to avoid suffering in very serious cases (the big question, of course, is what is 'serious').



    So far, most techological advances have been put to reasonable use in democracies . (I think Popper came up with this) There will have to be a great deal of public education about matters (to make sure democracies keep getting it right).
