    The paper is on Scripta Materilia, Volume 60, Issue 11, Pages 933-936 (why don't know why but I'm not able to copy and paste while using Chrome). It's available on ScienceDirect. It's over a year old and I don't know if there's any newer paper on the same subject by this group of authors.

    The usage of AFM/SSRM to make this kind of consideration is pretty new, at least for me but this is not my field, besides being also a materials scientist. The paper is interesting but I would like to see more quantitative detail.

    The summary defines black silicon as:

    silicon wafers treated with sulfur gases and femtosecond laser pulses

    Is this a thin film deposition (pulsed laser?)? Can you give a more accurate description? Maybe pointers to interesting papers?

    Thank you!

    Not difficult to build this if you work from GRASS source code for the GIS part. I believe it's C but if I recall correctly (I looked at it a long time ago) it's well written. Maybe just expand GRASS. Would be interesting to look at. I'm not working with GIS anymore but I could contribute, if someone else get interested.

    I disagree somewhat. Technical ceramics are in wide use like refractories. Or the semiconductor that powers your computer. In eletronics like diodes. Or as seals in advanced valves. Or the C-C thermal protection spacecrafts use. As electrodes in fuel cells. For a single example take a look at the multiple uses silicon carbide has:

    http://en.wikipedia.org/wiki/Silicon_carbide#Uses

    Or YSZ:

    http://en.wikipedia.org/wiki/Yttria-stabilized_zirconia

    Been a long time since I took that History of Technology in college, but we've probably been using ceramics for as long as we've been using metals. And even if we've been using metals since almost the dawn of civilization metallurgy as a science is pretty recent. De Re Metallica by Agricola was published in mid 1500. Metallography - our ability to understand metals microstructure using microscopes - started in the late 19th century.

    But your suggestions to Civ are right on the spot :)

    You can always charge a fuel cell by reversing the potential difference I believe. But, most of the time, doing this is not an energy efficient process. There are fuel cells made for situations like this (SOEC comes to mind).

  11. Re:Great, open source on Could Open Source Render Facebook the Next AOL? · · Score: 1

    Most installs I have done have gone off without a hitch, but when something doesn't work, it's hell trying to find an answer. Scouring through message boards and countless other sites trying to get an answer on the simplest questions is not fun. Plus, in many instances, the Linux community comes back with the harshest of answers saying that if I don't know how to recompile my kernel, or don't know how to fix a driver issue, I shouldn't be using Linux in the first place.

    Funny. Just like you, I tried to migrate from a mostly Windows desktop to Linux. My install borked completely - reasons unknow. But if there was something that surprised me a lot was the willingness of the community to help me. People - on the openSUSE forum and IRC channel - were amazing. Every obscure way to try to get things working was tried - and it finally worked. This myth that the community is harsh or unfriendly is unjustified. If you want to give Linux a try again I suggest you - if you can't find answers on a trivial Google search - to ask on the forums or on IRC. There's a lot of people - myself included - waiting to help.

    I found your position interesting.

    How would you apply an evidence-based method to what's fundamentally a subjective debate like law? What's truth in legislation? Legislation is the normatization of competition rules between social groups. What truth can be found on it?

    What? Did you read the link you posted? They tried to hire a research department and asked them to sign a NDA. WTF? What's more normal than this? A load of people reading your post, myself included, had signed one in some point of their lives. And the university just screamed "Oh, I'm important, BP wants to buy me off". Bullshit. On a situation like this any company will hire external consultants - and get them to sign NDAs.

    BP release live feeds to the spill. Get the footage. That's how close anyone will get to measure the volume. No better method. No hidden way. Get the footage they released and tell me how bad is the spill?

    I'm sorry if this sound really offensive, but you're fully out of touch with reality.

    JavaScript itself is not problem, even if "use strict" would come handy. The biggest problem is DOM and other associated APIs a JavaScript programmer must deal with. It's horrible. But along good practices (Crockford's Javascript The Good Parts come to mind) it is a very nice language to deal with.

    Take a look at Crockford's JavaScript: The World's Most Misunderstood Programming Language for reference.
