    90% of my work is debugging and even figuring out the failure scenario and testing against it. Writing the fix and new code is easy and quick.

    Much of the fresh water used today is fossil water. Desalination uses large amounts of energy, making it a nonstarter except in places like Saudi Arabia (until their oil runs out.)
    There is no shortage of energy, just the prices go through the roof. There is enough fossil fuel available to drive CO2 to 1,000 ppmv.
    Resources such as phosphorus and potassium are diluted into a unusable form (runoff) by agriculture.

    Efficiency improvements have never been able to compensate for growth. They aren't even today in the US. All reduction in energy consumption was due to the recession, as the recent record numbers for oil consumption show.

    Malthus was only delayed by the fossil fuel bonanza which is coming to an end.

  8. Something will have to give on How Much Should You Worry About an Arctic Methane Bomb? · · Score: 0

    It's blatantly obvious that numbers like population and energy, food and water consumption are unsustainable given the finite resources on Earth. The question is just what the brick wall will be that puts and end to it, or if it's going to be a combination of several.
    Personally I don't believe in the methane bomb but it will be yet another positive feedback (of 7 or 8) that will cause global warming to exceed expectations.

    The open Radeon drivers have accelerated 2D too and they're slowly trickling into the latest distros. F19 has them and Ubuntu saucy too, although in a buggy state last I tried.

    Two non-DP plus all DP outputs simultaneously is the rule. There are cards with up to six DP outputs.

  14. Re:Euh, no? on Ask Slashdot: Hardware Accelerated Multi-Monitor Support In Linux? · · Score: 1

    7850 has one dual-link and one single-link DVI output. There are no 7850s with two dual-link DVI outputs (except somebody might integrate an active DP->DVI converter chip.).

    GCN allows two non-DP outputs plus all DP outputs to run in parallel. I run three Korean 2560x1440 on the dual-link DVI and the two DP outputs on my 7850, plus one 1920x1080 on HDMI. This is supported by fglrx (sucks; crashy) and by the latest kernel/driver code but the only distro that has it today is Fedora 19. Ubuntu saucy should have it too but it doesn't work yet - at least not when I tried it two weeks ago.

    Rsync copies only changed files. The time-consuming part is reading all directories in the directory tree.

    How is traversing the whole directory tree with find different from what rsync does?
    Running a daemon that lists modified files using inotify might work.

    Right now EOMA-68 is trying to get off the ground with some basic low cost Allwinner based designs to build tablets, laptops etc around. Once those work (which is pretty close) we'll see some beefier cards. I can't wait for the tablets to become available, and then an A15 EOMA-68 board some time later.

    Bravo. Also the fallacy is that supplementing the few substances we happen to know about gives you the full benefit of eating the whole product. New substances are discovered every day and nobody is even thinking about testing out combinations of many of them. OTOH, that's what evolution has done for millions of years.

    You seem to confuse price and cost. I've been lurking on the ARM-netbook mailing list for a while; this stuff is dirt cheap to make in China. There's a reason why high volume low end Linux based systems have come down to $30-$40.
    USB2 and 100baseT is probably built into the SoC while USB3 or GbE needs an additional IC.

  23. Re:Wait.. on Plug Touts Expandable Storage Via USB Drives Plugged In At Home · · Score: 1

    It's hardware that costs about $20-$30 to make. USB3 and GbE would add $10 or so - very significant. I'd access it mostly via wireless and for that the speed is very adequate.

    However since their software runs on DD-WRT it should be possible to run it on more powerful HW too.

    It runs on DD-WRT so you can assume it's standard disk handling under the hood and that limitation can be raised by swapping out or configuring the OS.
