  3. Linux often cannibalizes Windows sales on Is LGP Going the Way of Loki Software? · · Score: 1

    worth noting that a game running well under wine is one compilation away from being native, thanks to winelibs

    (1) Compiling is only one small step on the way to release. There is all testing. Now consider the matrix of Linux distributions that now have to be tested. Letting your Windows version get run under WINE avoids this great complication.

    (2) More importantly, a native Linux version will often cannibalize Windows sales. Face it, many Linux users configure their systems to dual boot Windows in order to play games. Replacing a Windows sale with a Linux sale does not pay for the extra costs. The economics of Linux gaming is a bit more complicated than that of other platforms.

  4. Many with family plans on Verizon are waiting ... on Verizon iPhone Rumored For Early Next Year · · Score: 3, Insightful

    I was in business school recently. Lots of classmates purchased iPhones. An equal number wanted to but did not want to switch their family plans from Verizon to AT&T. If and when Verizon becomes an option I expect a spike in sales like we are seeing with the introduction of the iPhone 4. When I think about it, maybe its good for Apple to add Verizon in between phone updates and not at the same time. It would just be more strain on a new supply chain trying to get ramped up.

  5. Re:Small events still offer lessons for large even on How Bad Is the Gulf Coast Oil Spill? · · Score: 1

    Sorry, but not all of the effects are linear.

    True, but exponential is not the only other direction things could go. Constant is also an option. I am not claiming this is the case, but if a layer of surface oil seeks a natural thickness then a small reef may get slimed in a similar manner regardless of whether the slick is one mile wide or twenty miles wide - given an expectation that onshore winds and currents will cause the slick to have an easier time expanding laterally. So the effect on a given reef could be constant to linear? Again, I'm not claiming this is so, just questioning that the effect is exponential or some other extreme.

  6. Re:Volcano on How Bad Is the Gulf Coast Oil Spill? · · Score: 1

    Generally that channeling mechanism is a pipe of some sort, you can't just hope that the oil will float predictably upwards to a set location through a mile thick medium of salt water that has its own currents.

    My understanding is that it is a little more than just a pipe, there is an inverted funnel like structure at the base. That this wide mouth, relative to leak, should be fairly reliable at collecting once anchored. The real problem is displacing the column of sea water so that we have an upwards flow. Given the buoyancy of oil it shouldn't be too hard to calculate the volume of oil needed to displace the column of sea water. If the funnel exceeds this volume it should not matter how the pipe drifts or floats.

    The spill has been described as a volcano at the ocean floor. I haven't read anywhere that anybody knows how to cap it.

    My understanding is that since oil is not water soluble and floats that a capture device could be places over the "leak", the buoyant oil channeled to a surface collector and pumped out. That may be simpler than a cap that attempts to plug the "leak".

    Android also has a new business risk since it is a Google brand. When making that build-or-buy decision you want your partner to be non-controversial, you don't want your company to be collateral damage in another company's fight with the Chinese government. Fair or not, just or not, Google is a riskier partner than they used to be. This is not the only factor to consider but it must have been part of the Android decision.

    Wal-Mart's involvement is not limited to the trucks that deliver the goods that last mile. The Wal-Mart distribution centers are probably a more important asset. Shifting goods from regions not affected to those that are affected is an essential step in the overall process. I'd wager that some of those national guard, NGO and private trucks probably got their water via the Wal-Mart logistics pipeline.

    Go ahead, people, cheer for the corporations. None of them are doing anything for you. Your government supplies your drinking water, builds your roads, responds in the event of disaster, and much, much more.

    Not true. Wal-Mart and Home Depot did a better job than the gov't during Katrina. Say what you want about Wal-Mart's product sourcing but you have to admit they know more about delivering goods to remote corners of the country than anyone else. Interestingly, Wal-Mart was also a pioneer (1970s) of computerizing inventory and sales and in data mining. Wal-Mart monitors weather reports and when severe storms are *predicted* moves products that history shows will be in demand under such circumstances from unaffected regions to affected regions. When you see the Red Cross (also non-gov't by the way) handing out bottled water keep in mind that Wal-Mart probably delivered that water. FEMA is also supposedly turning to Walt-Mart for help with disaster logistics.

    The trouble is, the iPad (for all its slick design) is pretty much an enlarged (even embiggened) iPod Touch ...

    Perhaps I wasn't clear but a bigger iPod touch is exactly what many have asked for.

    ... It will appeal to those who are content to live in Apple's little garden of approved applications (so long as we use them one at a time),

    Actually its a rather large garden that offers nearly anything most people go looking for. As for one app at a time that is a pretty normal usage pattern, people tend to run an app for a couple of minutes and are done with it. Its not like a computer where one sits there working with something for hours. The one thing that needs to multitask and preempt, the phone, does. Also push notifications make many traditional background tasks unnecessary. While some complaints are valid, some are somewhat bogus attempts to apply old desktop methodologies rather than adopt newer methodologies that may be better suited for mobile devices. Like some users who stick to MS Office because that is all they know, some programmers like to stick to daemons and other background tasks because that is all they know. As someone who has ported applications and utilities between various desktop and server platforms I am sympathetic towards wanting to reuse legacy code but there is also a time to try something new.

    ... but those of us who really want a functional and versatile mobile computer with a small form-factor will remain frustrated.

    Perhaps, but that wasn't what it was designed to be. However I'd wait a while before passing judgement. A year from now it will be far clearer as to how well the iPad suits people's needs. Today, where no one has any experience with it and there is a bias towards wanting the familiar (more of the same) opinions are premature.

    This is not just a tablet computer, this is a big-ass iPod

    This is also exactly why so many slashdotters hate the thing. It's nothing more than an ipod so big I can't even fit it in my pocket. Why in the world would I want that?

    Back in the earliest days of the iPhone I bought an iPod touch. I configured it for the wifi at home, work and school and saw little need for an iPhone. I had a laptop but when in class or lying on the couch I found the iPad touch much more convenient for giving email or the web a quick check. After a week or so I recall thinking that I wish the screen resolution was doubled in both dimensions, it would be a much more practical browser. I don't think this was a very original thought, I've encountered many iPhone/iPod touch users who would have liked one that had a larger screen. There has always been a market for a device that was nothing more than a larger iPod touch, Apple has finally met and exceeded this customer want.

    Fitting the device in my pocket was a non-issue, I carried my iPod touch in my backpack. Had something like the iPad been available there were many days where I would have tossed it in my backpack and have left the laptop at home. Had the iPad been introduced at the same time as the original iPod touch I would have probably purchased the iPad.

Perhaps that made for automated processing. Other letters my grandmother received that were on regular paper and/or were multiple pages were shipped as the original paper rather than v-mail.

The implication that compromising non-essential liberties in the face of serious threats may be OK. In other words it is a gross distortion to quote Franklin in a black-and-white manner, he was a very complicated and insightful man that operated in shades of gray.

    Look at the actual quote: ""Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety." Liberty is qualified as essential, safety is qualified as both little and temporary. Keep in mind that Franklin wrote in a day when each word was carefully considered. There is a lot nuance in there, some wiggle room.
