  1. Ridiculous Speculation on No Moon Needed For Extraterrestrial Life · · Score: 1

    We have no fucking clue what it takes to support life as we know it, and we won't until we fully understand life and the process of abiogenesis. We do know a lot about where life cannot survive though, e.g. no oxygen, no water, etc. These equations are pretty much arbitrary.

  2. Re:Brain complexity and quantum science... on Does Quantum Theory Explain Consciousness? · · Score: 1

    I agree with you on the premise that quantum effects can't be automatically ruled out in a final (or even partial) explanation for brain function and consciousness. But a direct comparison between neuron count and transistor count makes no sense. The devil is in the details, and there is a lot of power in the architecture of (or lack thereof) the brain. The brain is massively connected and parallel, and we have nothing that comes close to the architecture of the brain. In other words, there is a lot to deal with before we even get to the quantum side of things.

    Check out work on the connectome (a mapping of connections of neurons in the brain): Human Connectome Project

    And check out this 3 dimensional cross section of actual neurons. It's the cube in the top center of the picture. The complexity of connections between even just a few neurons is immense. Each color is a different neuron: brain slice. Now scale that up to 100 billion, and make sense of it....

  4. Here are some reasons why on Does Quantum Theory Explain Consciousness? · · Score: 1

    I think there are more reasons why people tie quantum physics and consciousness together than has been discussed here. Anyone with a real understanding of science wouldn't claim that there is an actual connection between the two (unless perhaps they are a neurophysiologist and have actual experimental results). What people are doing is conjecturing and hypothesizing, and there is nothing wrong with that. That is quite different from claiming there exists an actual phenomenon. The reasons people conjecture are many, but here are mine:

    * Quantum effects at the microscopic level can have macroscopic consequences. A single photon or electron or other particle can be used to affect change at the macroscopic level. For instance, you could connect a photon detector to switch that would decide whether a train goes north or south. The state of a single electron within a computer can have massive effects on the stock market.
    * The observer is a critical aspect of quantum theory. Incoherent systems cohere (in relation to the observer) once the state is observed. An "observer" is really just another particle than interacts with the system in question. We as humans are not monolithic objects, but an enormous complex of particles, so when we "observe" a system, what does that mean? Does it mean when the measurement from the instrument hits your eye? Or when the signal from your eye hits your brain? Or when your cortex processes that data? There is a long complex chain of interaction that happens, so it's not as simple as the thought experiments in elementary physics books.
    * Our consciousness is the subjective experience of the particles that make up our brain. What state are these particles in in a quantum sense? Are they coherent or not? Can we "observe" our own brain? What are the implications of the observed system being the observer itself?
    * Since particles that make up the brain are normal particles modeled by quantum physics, they are also under the same rules, meaning they can be in a decohered state. Since we have already asserted above that single particles can have macroscopic consequences, is there a possibility that a single particle in the brain cohering into one state or another can have real consequences? Being that our consciousness is subjective, internal experience of these brain particles, is it possible that there could be a causal relationship between the subjective thought itself and external phenomenon, in one direction or another?

    I recognize these thoughts are not based in deep quantum theory or neurophysiology, but I still think that they reflect what people are wondering, and the experts in these fields aren't addressing the laymen very well when broaching this topic.

  5. This is news for dumb nerds. Or a troll. Or both. on Computer De-Evolution: Awesome Features We've Lost · · Score: 4, Insightful

    Seriously, this is a really ignorant article. Almost all the complaints are bullshit.

    PC-Write, the old DOS text processor I used to write my freelance articles with, and also PEN, a Unix screen-oriented text editor that was at BBN when I worked there, which I used for writing computer documentation and other projects -- could split the screen window as many times as I wanted (e.g., I could have five or six slices of a file showing). For editing long, complex documents, this was a great convenience. By contrast, Microsoft Word can only split the screen in two.

    VI anyone?

    I really miss the 'clicky' IBM Model M keyboards from the mid and late '80s, for instance.

    This is mass hysteria. For every fanboy that raves about their model M, there are 20 people that can't stand 5 minutes typing on these things. I tried it. Your significant other can't sleep at night, and your fingers get tired. They are old outdated pieces of shit.

    This keyboard isn't cheap, Hedtke concedes: "They were nearly $200 when CVT was making them directly, and the current Avant Stellar keyboard is around $325. But for many of us, it's more than worth it."

    You are a fucking moron if you pay $325 for this $20 dollar contraption. Don't believe the hype. The thing has a PS/2 connector for fuck sake!

    CONTROL-C and CONTROL-Q "which could kill an accidentally triggered program, along with the Unix Control-C and kill -9 for command line Unix. I'm not sure if anything exists that can do that as quickly at the GUI level.

    ctrl-c and kill -9 STILL work in *nix. You can even kill GUI apps using the command line, duh. Adding a GUI doesn't prevent you from using a terminal.

    "One, moving 'Destroy Window' -- usually indicated by a square icon with an 'X' in it -- from the opposite end of the title bar where I'd only click on it when I MEANT it, to right next to 'Iconify' and 'Maximize.'" This window control problem is now universal, according to Cattey: "It's on Windows, Linux and MacOS, as well as Solaris."

    What??? It is NOT universal. It depends on what window decorator you use. There is no "standard" for linux. Every distribution is different, and it's always configurable.

    Before there were scrollbars, command-line interfaces to Unix and DOS would paginate output and pause when the screen was full, until you requested the next screenful with the "more" command

    "more" is still there, but remember, "less" is "more".

    "As a developer, I found it very useful for when I ran scripts that produced a surprisingly large amount of output or a lot of error messages," says Franklin. "I did not need to run the command [more] over again in order to see it all. This feature has never been in another version of UNIX or Linux since."

    Umm, this actually sounds annoying as hell. There is a reason more and less are separate commands. If you REALLY wanted to have an automatic "more" command, you could write a shell wrapper. But in the end, some programs require a TTY, and having this automatic "more" functionality will break them.

    "XEDIT had the ability to restrict the file to a part, and have all editing commands, such as 'go to top/search and replace/select to bottom,' only work on that part of the file."

    Once again, VI. While not exactly the same, you can do analogous functionality in VI. And much more.

    "It could overlay hardware, firmware and regular memory as needed, and had no reserved memory sections. This let me write macros that were globally available."

  6. Re:An odd analogy on Professor Questions Sink-Or-Swim Intro To CS Courses · · Score: 1

    As someone who studied both orchestral music and computer science, I have a few comments. The equivalent of a "good orchestra" in computer science would be a good research lab or a good product team. These are also quite rare, but don't get the same fame that a "good orchestra" would. There are a few exceptions, such as the iPhone team, MIT media lab, and some others. Also, there are a lot of musicians out there that didn't make the cut. The difference is, in CS, if you don't make the cut, you can still get a job and learn the trade, because the massive amount of computer work out there. The same is not true of music, so if you want to make a living at it, you have to be extremely good - there just isn't a lot of work out there. Mind you, there are gigs that don't require a lot of talent - making music for commercials, cartoons, shitty video games, etc, but the amount is still much less than the amount of computer work. Also, the purpose of CS work is usually quite pragmatic, whereas music is usually quite aesthetic.

    My point is just that you can't directly compare the two, because the differences are great.

  7. Coffee Lobby on Coffee Wards Off Cancer · · Score: 2

    Is it just me or does there seem to be a serious coffee lobby / PR organization at work here? No exaggeration, every three months for the last couple decades I've seen some story about the benefits of coffee on health. It is clearly legal because it is a workers' drug. It keeps people focused during work, while leaving them slightly frazzled afterwards so that they have no energy for anything else.
