  1. Re:Dubious article. on Cheating At Roulette May Be Legal In UK · · Score: 1
    I remember a similar story. The first day the guy was mostly just writing down the numbers. The casino owners probably assumed he was just annother crackpot. He recorded the values for all the tables, and later analyzed them finding at least one table with significant bias. (The bias needs to be large enough to overcome the payout bias that favors the house.) So the guy played at that table, and starting winning big. After a few days the casino caught on, and swapped the wheels. It took the guy a part of the day to figure out what happened, but once he did, he was ableto locate his wheel by a scrath on it. So what the casino did next was buy a wheel where the dividers between the numbers are swapable. Under this system the guy lost most or all of the money he won.

    The swappable divider system is virtually perfect. Whenever they are swapped the bias of the wheel changes. So simply change the bias of the wheel fequently enough that there has not been enough time to gather enough statistics to exploit the bias. (change it say every 60 min. or even every 30 minutes if paranoid). Have an extra wheel ready to swap with the current one so that there is virtually no downtime due to randomizing the dividers. One cannot even build up statistical information over time of the bias with each divider confuguration because the dividers would be too difficult to distinguish. A paranoid casino could even have many extra divers (thousands) to make the number of purmutations prohibitavely large.

    DRM does mostly hurt honest people who are not technically inclined. However it does prevent dishonest people who are not technically inclined from "pirating."

    In other words: It hurts honest people, but because it prevents casual "piracy", it is deemed a success. Nobody ever expected DRM to stop "piracy" completely.

    The parent was not a troll. The parent was describing Vista, and asking: "Since when has Apple's plan been to release something like Vista?" (late, with many feature missing, unreasonable specs, a large number of options, and a fairly hefty price.) It was a little hard to notice it, but the parent does have a point. Apple has a very different business model than Microsoft.

    Now as for vista's versions. Vista actually has fewer versions than XP. The simple fact is that many of XP's versions were rarely heard of. For home users in the US there will be only really three choices. The italic options are the ones home consumers will see.

    • Vista Starter: Stripped down version to be sold only in developing countries. (Cheap but very crippled).
    • Windows Vista Home Basic: This is roughly equivlent to XP Home.
    • Windows Vista Home Premium: This is roughly equivlent to buying XP MCE.
    • Windows Vista Business: Roughly equivlent to XP pro for normal businesses.
    • Windows Vista Enterprise: Roughly equivlent to XP pro for Enterprise businesses
    • Windows Vista Ultimate: Includes all features of all versions. Roughly equivlent for home users of buying XP Pro, except that it will include the Media Center features.

    And new to Vista is Windows Anytime Upgrade which means if you buy Home Basic and realize you really wanted Home Premium or even Ultimate, you can use a control panel applet to upgrade. You may need your CD for this. The anytime upgrade pricing will hopefully only be slightly higher than the price differential between versions.

    Technically paypal is misreading their policy.

    They ban game enhancement devices that "enable the play of import software and/or back up versions of software". Obviously that is only a problem if those could not be trivially done without the software. I'm fairly sure it was possible to play backup copies without ScummVM, so ScummVM is not enabling the users.

    It also does not qualify as a game enhancement device because it is a game component, not an enhancement device. It is a replacment for a shipped component, but it is still a component. If the parent's post is correct then it is even a semi-official component. The only sane reason for paypal to ban game enhancement devices is to avoid the possibility of being sued by a game maker. In this case, that is not going to happen.

    It is also clear that this was not the type of device that Paypal was thinking about when they wrote that. They were almost certanly thinking about things for consoles that in addition to cheating could be used more or less like a mod chip. That is not the case here.

    Oversubscription is a fact of life. Buy a plane ticket and you have a chance of being bumped because the flight was oversold. Buy a movie ticket and you have a chance of being barred because they hit capacity. Many businesses oversell because they cannot guarantee every sale will actually be used. If they didn't oversell, planes might fly much less than full, movie theaters might play to almost emoty houses, and while that isn't the rule, it happens more often without overselling and that is seen as a loss.

    The prblem with that is that it is unfair and absurd. Airlines should never oversell tickets because if they sell all tickets they have made a full plane's profit. If they really want to avoid flying with empty seats, they can sell standby tickets. The same goes with a movie theatre. Oversubscribing (instead of standby) is unreasonable.

    Meanwhile, the publishers have a new way to force you to buy new. My physics book came with a code for online homework, and an electronic response clicker thing. The code is only good once, and my professor requires we do it. A used book is about $90, however if you have to buy the code for the homework seperately, it costs about $50. The clicker is like $20 seperatle, and the frequency code card for it is like $40. A new textbook, which includes all of this for "free" is $140. By adding in 1-use only crap, and convincing lazy profs to use it, they have completely killed the secondary market for that book.
    I love the way the codes for the online homework courses are all created by the same company, despite being used by many competeing book publishers.

    Anyway, the publisher usually provides the instructor with a re-usable code code that all students can use for the online homework. I know that I have not even removed the shrink wrap from my chemistry book, but have enrolled in the online homework (The best one I have ever seen too!). Always ask the prof for a free code before opening the code booklet that comes with your textbook or buying a new code booklet if your textbook is used.

    Now, as for the clickers, I am only familiar with Einstructions's CPS unit. You buy the clicker, and in theory you could get a used one. (You will have to work with the previous owner and einstruction to have their account removed from the database, so that you can enter the serial number into your new account, but it is possible). You then must enroll the clicker into your courses. Yo do this you must pay online with a credit card, use a code card. Code cards can be bought at the bookstore (DO THIS! EInstruction makes less profit like this), or may come packaged with a textbook. The ones that come with a textbook come in two forms: Free enrollment, or 50% off.

    The reason you pay per class, or per semester (depends on how much the school has payed EInstruction) is that EInstruction is offering a service. Just about everyting to do with the clicker operated over a web service. There is no techincal reason for this, as stand-alone software could obviously be used. EInstruction claims the reason is that the webservice makes things easier for the Prof. That is a very questionable claim.

    But the clicker really does not have anything to do with forcing you to buy a new textbook.

  16. Re:The good old days of DOS on Inside Vista's Image-Based Install Process · · Score: 1

    Really, you often did not run more than one version of dos. If you had more than one folder, you were likely just using the command.com of the newer DOS.
    You were almost guarenteed to be running the kernel from the more recent DOS. This is because the files with the kernel were stored in the root directory.
    However the two folder did have seperate copyies of the userland commonents, so it is more like a chroot than booting into the other version of DOS.

    However, most versions of Windows did allow multiple parallel installations. With these you really were booting into two seperate operating systems.

    Your idea for linux in C:\lin is not as far fetched as you might think. I'm pretty sure that Windows 98's boot selector would have been able to load
    loadlin.exe (That program runs in true DOS mode, and basically pushes the DOS kernel out of memory, and then loads the linux kernel.)

    Linux should even be able to boot from fat32, so what you are describing is entirely possible.
    By abusing the XP's bootloader support for legacy OS's (non-nt based windows) you should be able
    to still do this.

    I'm feeling verbose today, so I will explain how this is done.

    1. Install DOS on a fat partition (Ideally use MSDOS 8 from Windows ME), It really should be fat32.
    2. Copy the bootsector (*not* the MBR) to BOOTSECT.DOS (use a utility like 'dd').
    3. Back up all the files. (I'm not sure if XP clobbers DOS if a legacy Windows is not installed).
    4. Install Windows XP, being sure to keep the partition as FAT32.
    5. If any of the files from MSDOS is then missing, restore it from the backup.
    6. Now we edit C:\boot.ini. (It is by default Read-only, hidden, and system).
          If you see a line that mentions MSDOS then apparently XP setup did this step for you. Simple change
          that line to read linux. Go to the next step. Otherwise, add a second line to the
          "[operating systems]" section that reads (omit the brakcets):
                {c:\bootsect.dos="Linux">}
    7. If all went well, when booting Windows, if you choose Linux at the prompt
          you will boot into MSDOS. Now you must simply setup loadlin.exe to load a kernel,
          and boot from C:\lin. You will also need to install userland components, etc.
          This is the hardest part, and I cannot help you with it, but it should be possible.
    8. Finally edit config.sys or autoexec.bat such that it runs loadlin.exe

    (It is interesting that people claimed non-NT based Windows to not be an OS, but merely a shell. Windows has always had its own kernel, which should make it a complete OS, even if it does run on top of another.)

    Casinos also keep track of player's winnings, and will share these statictics with their competitors. If a player is consistantly exceeding the offical odds, for a significant period of time, then they are likely to be banned.
