    Absolutely. However, the consequences of those very predictable edits is not well understood.

    That's saying that the consequences of editing a text file with emacs are not well understood; it's a meaningless statement, since the consequences depend on the edit.

    There are many edits with predictable consequences. There are many edits with unpredictable consequences. But the range of consequences is pretty straightforward: most of the time, nothing happens, and rarely the person either gets sick or gets better.

    I think the better analogy is it is like using emacs to edit a large binary executable (something I've actually done before in trying to crack licensed programs). One would hope that, through a debugger, one has a good idea of what the edit is supposed to do in order to exact the changes expected. Even when I was pretty sure I understood what changes I needed to make, I was still not eliminating the license checks, and causing random crashes. I don't claim to be an expert at doing this. However, our biological understanding (the debugger) is currently similarly lacking, if not more so. We know that editing DNA sequences modifies the transcribed proteins, and that there are also epigenetic factors that are affected (which was only established relatively recently), among other things (possibly yet to be discovered). I personally believe it is presumptuous and premature to declare that consequences of edits are predictable, since there could be subtle long-term decades-later effects of edits, or perhaps consequences for progeny of those subject to gene editing.

    There are some implausible scenarios under which gene editing might pose a risk to other humans, but regulations are not going to stop those anyway, so you might as well not bother making those illegal.

    What should be, and what is, as you point out, are two different things. I would rather be overly cautious in the case.

    Gene editing is extremely well understood: it makes predictable changes to human DNA. That's its attraction.

    Absolutely. However, the consequences of those very predictable edits is not well understood.

    Because it's not always clear they actually enjoy those houses. A lot of the motivation for buildding mcmansions is one-upsmanship. I've lived in the bay area more than 30 years now and I see fellow Chinese build these monstrosities to show the world their wealth. If you ask them about houses they decry the lack of privacy and lack of yard. It's infuriating to bystanders because they are garrish. It's like if your neighbor painted their house bright green. They build this castle that overlooks your house and your windows and absolutely does not fit in with the original look and feel of the neighborhood.

  4. Re:Julia needs arbitrary array indexing base on Julia Programming Language Receives $600k Donation · · Score: 1

    I couldn't agree more, especially for a language that deals with math and linear algebra. When accessing submatrices of matrices and doing advanced linear algebra manipulations, using 0 based offsets leads to far more natural indexing, reduces the need to constantly subtract and re-add 1, and leads to fewer chances to make silly errors.

    And what if those aggressions and hatreds were directed at you or people you cared about? What if those anonymous comments threatened harm? How lightly then are you willing to take it? There's definitely a balance that needs to be struck between free speech and its control, and it seems to me Yik Yak does more harm than good.

  7. Re:Does it really matter? on ARM In Supercomputers — 'Get Ready For the Change' · · Score: 2

    On the point or portability, there's then a distinction of your focus. If you do research on numerical methods, then yes, you would write highly optimized code for a particular machine, as an end in and of itself. I myself am merely a user, and our research group does not have the expertise to write such optimized code. We pay for time on supercomputing clusters, which constantly bring online new machines and retire old ones. Every year our subscription can change, and we are allowed to use resources on different computers. Therefore, from my standpoint, portability is very important. Otherwise, if we were to write our own code in-house, we basically have a 1 year (ok, fine, maybe 2 or 3 year) window in which to develop, test, and run it. It just doesn't seem worthwhile to spend so much effort developing a one-time use piece of code. I'd rather write something which will outlive my stay in the research program.

  8. Re:Does it really matter? on ARM In Supercomputers — 'Get Ready For the Change' · · Score: 5, Informative

    As someone who does heavy duty scientific computing, I wouldn't say that "most" of the actual process power is in GPUs. They are certainly more powerful at certain tasks, but most applications run are legacy code, and most algorithms require substantial reworking to get them to run with reasonable performance on a GPU. Simply put, GPU for supercomputing is not quite a mature technology yet. I am personally not too interested in coding for GPUs simply because the code is not portable enough yet, and by the time the technology might be mature, there might be a new wave of technology (like ARM) that could be easier to work with.

    Why is there so much hate for netbooks? I've got a 10 inch eeePC from 3 years ago and I absolutely love it. I use it almost everyday and it still has great battery life of 3-4 hours down from 7-8 originally. Plus having a nearly full size keyboard makes doing actual work possible.

    This is not entirely true for a framework like OpenGL. You surely can add your own features or improve performance on your end, but these changes must be incorporated into graphics card drivers by vendors in order to have a wide audience. This is where it helps to have the industry clout that Microsoft does (not that this is necessarily a good thing, but they have the power to push through changes into hardware using their DirectX specs).

    Note that MathType is only really for adding equations into Word documents; it supplants the MS Equation editor, and probably isn't meant for a whole lot more. My adviser (in EE) also uses MathType for formulas and class notes. However, these tend to be short documents that are less than 10 pages long typically, with no need for serious cross referencing. Once you start trying to write serious documents on the order of a hundred pages, with cross references all over the place to equations, tables, and figures, MathType and Word's capabilities begin to pale compared to LaTeX.
