  1. Re:Trolling? on The Day Leo Traynor Confronted His Troll · · Score: 1

    Now, this, this is an example of trolling. Slightly absurd, somewhat believable statement which derails the thread.

  2. Re:Lots of work has been done here on All Over But the Funding: Open Hardware Spectrometer Kit · · Score: 1

    LEDs will still have a pretty broad spectral response so you'd have overlap, and need quite a bit of gain. Try one of the taos colour sensing chips, those do RGB+all with programmable gain and digital output, it'll make the project pretty simple and much more repeatable. you can also do one clear NIR phototransistor with selectable filters for colours. That'd be manageable. For my project, I am using, currently, a clear phototransistor and illuminating the target with a specific LED colour. I think someone has done something pretty similar (but reflection rather than transmission) on instructables too, but I can't dig it up.

  5. Re:It is a RO membrane, just a really good one on Making Saltwater Drinkable With Graphene · · Score: 5, Informative

    The abstract: "We show that nanometer-scale pores in single-layer freestanding graphene can effectively filter NaCl salt from water. Using classical molecular dynamics, we report the desalination performance of such membranes as a function of pore size, chemical functionalization, and applied pressure. Our results indicate that the membrane’s ability to prevent the salt passage depends critically on pore diameter with adequately sized pores allowing for water flow while blocking ions. Further, an investigation into the role of chemical functional groups bonded to the edges of graphene pores suggests that commonly occurring hydroxyl groups can roughly double the water flux thanks to their hydrophilic character. The increase in water flux comes at the expense of less consistent salt rejection performance, which we attribute to the ability of hydroxyl functional groups to substitute for water molecules in the hydration shell of the ions. Overall, our results indicate that the water permeability of this material is several orders of magnitude higher than conventional reverse osmosis membranes, and that nanoporous graphene may have a valuable role to play for water purification." Emphasis added for why, and the introduced problem

  6. Re:In other news on The Hobbit's Higher Frame Rate To Cost Theater Operators · · Score: 1

    Aside from the fact that I'd have to leave the basement to do this, playing FPS's at ~24 fps and ~60fps is a noticeable improvement of high fps, so it can be done.

  13. Re:Extract money from the lazy? on OS X Notifier App Growl Goes Closed Source · · Score: 1

    The problem isn't the cost, nor the quality. It's the un-announced, and under-informed/explained changes. Growl at least seems to have said they are abandoning free software and going pay-only (took a lot of digging to find a neoffice post claiming the same). Except elsewhere in this topic, it is said they are still releasing the source, etc, so maybe that wasn't their intent. I can't consider it paying for support, especially with neooffice. I don't think they want to offer support to non-corporate, see the price of admission to the forum.

  14. Extract money from the lazy? on OS X Notifier App Growl Goes Closed Source · · Score: 1

    Growl prompts you to upgrade and sends you to the site when you are told you need to pay. Perhaps some do. Some time later, it becomes open source again, and perhaps freely downloadable from the website. Didn't neooffice do this (first part at least? They were also quite hush-hush about the transition to no free binaries(for the current, and only 10.7 version)).

  19. Welcome to canada? on University Proposes Tuition Based On Major · · Score: 1

    It is this way at the university of waterloo, and I believe canada. I paid 2500 a semester (3/year) whereas CS and ENG paid double or more. Doesn't seem to have reduced enrollment. If anything, the long-term effect is that the higher value departments (those that can charge more per student) become more important in the school to the detriment of the others. Waterloo does have a bit of an engineering/math/CS specialty, and I'm sure the increased revenue does nothing to dissuade this continuing.
