  1. Re:Comparing a Car to a Two Stroke Engine?? on Green Cars You Can't Buy · · Score: 1

    Actually, nearly all lawnmowers are built on four-stroke engines. Notice how lawnmowers have separate fuel and oil tanks. Weedwackers and chain saws typically use two-stroke engines because they need to be able to run at different angles and orientations to do their jobs. These engines run on a mixture of fuel and oil, which they use simultaneously as a lubricant and a fuel. In simple four-stroke engines, the oil from the oil pan would run into the piston if the engine were tilted to extreme angles. Four-stroke engines make power 1 out of every 4 strokes, while two-stroke engines make power every other stroke. Four-strokes are generally more powerful, more efficent, and cleaner, though, because they burn a much more pure mixture of fuel and air, with very little oil contamination.

  4. Re:Yogi-esque on US Pennies To Be Worth Five Cents? · · Score: 1

    What's the long-reaching economic impact of destroying a piece of currency to obtain its more expensive raw materials, thus resulting in a positive sum value change? If the raw materials in a penny are worth about 1.1 cents, it probably costs slightly more than that to manafacture (maybe another 0.1 cent). If you melt it down and sell the penny for a .1 cent profit, then it costs the government 0.2 cents every time you make 0.1. I don't know the long term effects, but if you're doing this on a large scale, you're basically costing the government a lot of money. There are now fewer pennies in the world and the government has to pay to make more, continuing the cycle of lost value.
  5. Re:iPhone implied feature on Sony and Universal Prohibit Sharing Via Zune · · Score: 3, Informative
    Actually, music purchased from the iTunes store is locked down about equally as bad as these files in the Zune. iTunes will ask your for the authorization password if you try to play someone's DRM'd music over the nextwork. No password, no music for you. Only non-DRM music (stuff ripped yourself or have otherwise "acquired") can be shared.

    I'm pretty sure the Zune would let your share non-DRM'd mp3s as well.

    My understanding is that the drinking age was set by individual states so that they could get money from some highway construction bill in the late 70s or early 80s. I don't think/i it's set at the federal level, it's just that no states will turn down free* money.

  8. Microsoft behind Google? on Vista the End of An Era? · · Score: 1

    Perhaps Microsoft's online offerings (eg. Office Live) don't have the marketshare of Google's Calender, Spreadsheet, and GMail, but think about how those users get to Google's services. A vast majority of the online population is surfing under some flavor of Windows and some version of the Internet Explorer browser. Sure, Firefox is increasingly popular [and so is Linux], but virtually all personal computers these days come with Windows XP and IE, and most users do not take the trouble to change that. The same will be true for Vista and MS's future offerings.

    If their codebase is growing too large to effectively maintain, they will do the wise thing and stabilize the interface while re-writing the underlying OS. It's not impossible to imagine MS going the Apple route and re-building their operating system on OSS, just adding some kind of compatability layer to provide a minimal amount of backwards compatibility.

    So, perhaps it will be the last Windows of based on that codebase, but certainly not the last of it's kind. Microsoft's various OS's play a key role as a brigde to the internet for a majority of users, and the company has enough pull with PC manafacturers to keep its position on the desktop for some time. Of course, the comments made by a number of other Slashdotters make sense, too. An online-OS (OOS?) relies too much on the persistence of the connection, and reduces productivity to zero when the link to the net goes down. This is something Microsoft's business and education customers are not going to go for.

  10. This is rediculous on Mainstream Media To Start "Crowdsourcing" · · Score: 1

    This is probably one of the craziest ideas I've ever heard of for the mainstream media. I can handle bias and even the occasional factual errors and omissions, but having laypeople conduct your investigatory journalism for you? The problems are just too numerous: lowering of research and writing standards, dealing with too much or just plain unbalanced information, corporate red-herrings, conflicts of interest, fanboyism, private agendas... these are just a few of the reasons news corporations have private, [ideally] independent, eduated staffs of researchers, writers, and editors. And, not coincidentally, this is why blogging does not count as news.

  12. Read the Source code? Are you serious? on Viral Videos That Really Are Viral · · Score: 3, Insightful

    Outside of the scope of this article, there are dozens of reasons not to relase your sourcecode, among the most common being the proffit motive. A A lot people look at OSS with are "why by the cow when you get the milk for free" attitude. What about companies that haven't yet copyrighted or patented the algorithims in their software before they go to market? And do you really think companies like Adobe and Autodesk are ashamed of their award winning flagship software packages? Quite honestly, your last argument is utterly rediculous. To bring things a bit closer to home, it's often way simpler, smarter, and faster to distribute codecs in binary form. People just want them to work right away without firing up the windows equivalent of "./configure --with-notrojans". If they have trade-secret compression algorithims, then your company may not want to give them to your competitors. Finally, even if the source code were made public, users have to read thousands of lines of code before knowing if it was "safe" or not. I seriously doubt you'd find any comments that say ""// Computer-destroying virus begins here". And safe is a relative term, because for some machines a segfault is just as bad as a trojan horse.

  13. Re:What's the big deal adding a paper trail? on Voting Machines Banned by Dutch Minister · · Score: 1

    As a voter, I'd rather be given something akin to a receipt. The machine could print two of them, one for my records, and the other to place in the ballot box, which is a backup for the machine's count. Each pair of receipts could also get a random barcode, so in the event of a (manual) recount it would be easy to check if your vote was actually counted or not.

  14. One reason not to encrypt the windowing system on How Encrypted Binaries Work In Mac OS X · · Score: 3, Informative

    WM's are huge apps and decrypting one before every startup would add a lot of work that has to be done at boot. According to the article, "the SystemUIServer binary within SystemUIServer.app", is encrypted and that is presumably a larege component of the WM. Also, it's virtually useless without the the dock and finder anyway.

    I know this is a tangent, but... Ritalin is a thing of the (way) past. Most everyone I know (incl. myself) who has been diagnosed with ADD gets Adderall or Adderall XR (extended release) these days, which is a mix of 4 different amphetamine salts. There are some new-school drugs like Concerta, but none of the people I know like the way the new stuff feels, which is not to say that being on uppers all day was a good feeling either. I gave up on the drugs about a year ago and have been working on using willpower and self-discipline to accomplish the same ends. With enough work, you can get a similar level of focus without any of the side effects associated with the medication.

  17. IP rights are the least of it on Students Protest Turnitin.com · · Score: 4, Interesting

    When I was in high school a few years ago, they began to make us submit our papers through this system, too. It would read through the document and produce a number based on the likelihood that you cheated. I once wrote a simple paper for an English class and it ranked it as having a 27% chance of copying or cheated. The system was definately buggy and false positives can do an awful lot of hurt to a student's credibility.

  18. Re:Should all copying be considered infringement? on OLGA Shut Down by DMCA (again!) · · Score: 5, Informative

    Mod parent up. This has long been the theory supporting the legality of tabs. The writers of tabs see them as learning tools at best or derrivative works at the very worst. The fact that tabs are not written out as sheet music also encourages guitarists to purchase CDs in order to learn to play at the correct timing, which is not written into the tablature. Tabs are by-ear transcriptions and their availability has helped untold numbers of budding guitars develop their skills without the need to [buy and] learn from expensive sheet music. Tab websites have slowly been closing their doors due to threats from sheet music associations, the industry, and fear of punishment under copyright laws that leave very few fair use rights in them at all, heavily favoring the recording companies. It's a real shame that yet another one has been pressured to go under.

  20. Direct vs. Indirect Access to articles on Google Reveals Payment Deal with AP · · Score: 3, Insightful

    From what I saw on the Associated Press's website (http://www.ap.org), they have no free access to their news content. I would guess that Google's aggregator has been getting its AP - and all other - content from the AP's customers, such as the New York Times and other large newspapers. The good thing about pulling from several of these sources is that a variety of sides to one issue show up in Google News. I'm worried that Google's new deal with the AP will lead to a direct pipe for AP articles in whatever the new product is. Every source has its biasses and a domination of AP content could lead to a deterioration of the level view I'm used to getting by seeing a number of articles on the same subject throgh Google news.
