  1. Re:Thinking through the uses... on 'Merging Tsunami' Amplified Destruction In Japan · · Score: 1

    There's plenty of power plants along the Japan sea as well. I strongly suspect the placement is dictated more by the availability of a good site and local political willingness to accept a nuclear power plant within the prefecture.

    it is split in two parts only; eastern and western Japan, and the split is because the power frequency differs, with 50Hz in the east (including Tokyo and northern Japan) and 60Hz in the west with Osaka, and Kyuushuu and so on. The grids are pretty dense otherwise, but there's only three points capable of converting power between the two grids.

    And the reason has nothing to with being mountainous. Simply, as electricity was first introduced, different companies in Tokyo and Osaka bought their power generation stuff from different places, with the Tokyo company buying from Germany (which used 50Hz) and the Osaka one from the US (which used 60Hz). With no regulation in place for the burgeoning industry and no short-term reason for the companies to agree over such things, the country split, electrically, and the split remains today.

    We have direct-read meters in our condo. They're connected to a fiber net running throughout the building. The door cameras and intercom, water and gas meters and the fire alarm all use the same fiber. As a bonus, since they ran more fiber than the utility stuff uses, this also gives us very cheap fiber broadband. It's behind a building-wide router so I can forget about having a server or anything, but it's still a high-speed connection at a pittance.

    Don't be fooled by simple visual impressions though. Macs all look the same, while other machines all look different. The logo stands out and makes it look more prevalent than it is.

    I was at a summer research school last year, and my impression the first few days was that more than half - and perhaps more - were using Macs. When I actually counted, though (not all lectures are absorbing and relevant to your own work), the reality was that about 25% were macs.

    The most used OS, by the way, was Linux - typically Ubuntu booted native or in a virtual machine - since that's where the software tools we use have the best support.

  7. Re:Argument about Unity? on Is SaaS Killing Native Linux App Development? · · Score: 1

    As a developer, I rather like it. The integrated top bar gives me another vertical line for code and text, and the pp-out scrollbar gives me another horizontal position (gvim isn't adapted to it yet, unfortunately).

    It does need some tweaking to be good for a power user, though, and I think Ubuntu is making a big mistake in not exposing those settings properly. You have to google for a lot of those settings and they're not obvious. That's really the main issue, not Unity itself.

    Well, if you're going to build a railroad, for instance, you'll need a huge load or iron, and redstone and gold for the power. That alone will take a whole lot of digging for resources right there.

    And that's where I think the brilliance is of Minecraft: You're basically in a free-form building game, but you have to actually work for your resources, and do so in an environment that is actively looking to kill you.

    One thing: you have no RSS feed for the journal. Not the actual contents, I hasten to add; just a low-volume feed for announcing new issues would be really helpful. There is no way I will remember to check for new issues, and RSS feeds are a great way to be reminded when there's new stuff on a site I follow.

    Not for workstations, I agree (I have one as well at work). But once you start piling up CPUs in racks by the hundreds the raw power matters less than the power per watt. Power and heat dissipation becomes the limiting factor in how much processing power you can cram into a given facility, or the total size, construction and installation cost for a bespoke facility. And while the Xeon is fast it and its support circuitry is rather a power hog.

  13. Re:This *is* big on Tipping Point For Open Access CS Research? · · Score: 4, Informative

    You do realize, I hope, that many, if not most, for-profit journals also have publication fees? That includes a good number of very high-profile journals, and the fees are generally as high or higher than open access journals. Journal of Neuroscience, for instance, will charge you just north of $1000 for a paper - $950 in publication fee and $120 just to submit the paper.

    Open Access journals are in general no more expensive to publish in that for-profit journals, and they have more generous exceptions for people that find it difficult to pay.

  15. Re:Nice distro but they messed up the desktop on Ubuntu Turns 7 · · Score: 1

    Just another single datapoint of course, but I've been using Linux (and Sun OS before it) since the mid-90's. I'm very much a technical user and spend most of my time in a terminal one way or another.

    And I find Unity in 11.10 to be just fine. It does two really, really good things: It gets out of the way when you push windows onto the panel and similar. And it puts the window controls and menu bar onto the top panel. Both give me more space â" vertical space, especially â" for the applications I use. And as a bonus I still have the panel controls like the clock and mail notification visible even with the screen filled with windows.

    Using it - well, it works. Don't really understand what people miss with it. Not better or worse than menus; the application list thing really works like a menu already anyhow. What they still need to do is to expose some more of the settings in the default settings list, such as screen font, and size of the icon panel thing on the left. They're easy enough to configure already, but it'd be better if you didn't have to install something to do so.

    One tip: install and use Synapse. Much like Gnome Do, it's a great way to launch programs and get at files you use. Way better for a power user than any menu.

    And that's the root of the mistake I think they did. They should have taken the effort to recreate or port the Gnome 2 interface as an easy to choose alternative. People will come over to new things when they can do so at their own pace. Most negative reactions are really about being pushed onto the new thing by the upgrade, rather than about anything to do with Unity itself.

    What to use?

    Unity.

    Seriously. You spend all your time in shells, editors, Eclipse and what have you. The desktop is just a launcher for your real stuff after all. The perfect launcher is one that lets you run your stuff and gets out of the way once you do.

    Unity is great at getting out of the way; I get more screen estate â" especially vertical estate â" than I do with other environments, and that translates into more visible lines of code and shell command output space. I spend most of my day coding and writing, and I would not want to return to an old-style desktop layout again.

  20. Re:Lost some funding? on Ask Slashdot: Best Use For a New Supercomputing Cluster? · · Score: 1

    GPU-based machines' effectiveness depends a lot on the precise type of work you want to do. If each node can run largely independently, with little data exchange and with their working data set stored locally, they are really fast. If you need a lot of communication between nodes (simulating a neural network with large fan-in/fan-out for instance) then your savings are much more modest.

    And you need to account for the time spent developing as well. Not much use saving a week of computer time using a GPU solution if you have to spend three extra weeks in development. It is somewhat telling that at the place where I do my large-scale computing work the regular clusters are always fully utilized whereas the GPU-based cluster sits idle much of the time.

    No, not really. They were a newly started/aqcuired network (softbank bought a failing network wholesale) with few customers and a reputation for lousy infrastructure. They were the only network willing to accede to Apple's conditions for selling the iPhone (rumour has it Apple was holding out for NTT Docomo to the end but the negotiations fell through).
