    No my reply was strictly a reply to the parent post. Even programmers find compiling to be a pain, especially if software is not pre-ported. I really don't see universal binaries as very valuable at all, given that they don't help with the porting. Once source is ported there is no reason for the porter or maintainer to ever compile for that platform again. Just create an auto-compilable source package. Gentoo is the ultimate example of that, but even the vast majority of binary packages for Debian architectures are auto-built from source.

    Perhaps if LSB were working well enough that all x86 GNU/Linux distros could run the same version of an app, and all PPC GNU/Linux distros could run the same version of an app, a universal binary might be something a proprietary vendor for Linux might like, since it would ensure all users got a version that would work on their architecture (if theirs is supported at all) rather than accidentally downloading/ordering one for a different architecture.

    Bobbs-Merill v. Straus Is not directly applicable. A very important quote from the ruling: " There is no claim in this case of contract limitation, nor license agreement controlling the subsequent sales of the book.

    The court did not rule that it was not possible to license a book, but merely that a notice printed in the book does not cause a license to come into existence out of mid air.

    Had the copyright holder had in place contracts with the wholesalers to only sell the books to retailer who accepted the terms to sell the book at no less than $1, the court may have ruled differently.

    However some later cases may actually be applicable, and it would not surprise me if they made it almost impossible to license a book in a way similar to EULAs.

    Nevertheless it is most definitely possible to license a book, in which an owner maintains legal title to the book but possessor has rights to use the book. Indeed this is done often enough in some circles, but in those cases the way one acquires the license is usually very different from the retail shopping experience, and often involves contracts signed by both parties, and may even not be contracts of adhesion, allowing negotiation of terms. In the case of software licensed in a similar way, nobody really thinks the License may not be applicable.

    EULA's are slightly different and there are are the clickwrap EULAs, which may be legally different than the inside the box EULA's which in turn may be legally different than the Written on the Box EULAs. The law here is about as far from settled as is possible, and what is really needed is a supreme court decision that chooses to decide the matter for all possible cases, rather than just the specific case at hand. Unfortunately the supreme court usually chooses to not to be so sweeping, so sweeping decisions are generally a side effect of the use of specific logic in a decision that has not be fully limited to the specifics of the case at hand.

Of course, that still sounds like too large an error top have occured from just that, but lets pretend it did.

    There are several issues here. For missiles travelling at such speeds, using a system clock counter based on 0.1 second ticks sounds terribly coarse to me. Second, since 0.1 seconds are the baseline resolution of the system, the system should have been using floating point numbers where '1' corresponds to a decisecond rather than a second. Then the time counter would be exactly expressible in the floating point format.

    Lastly, if the floating point format really needed to be in units of seconds, rather than deciseconds, the time counter should have been loaded in, having an exact representation, then it should be divided by 10, which has an exact representation. This is all prety basic to anybody who has even a limited understanding of floating point. If you understand the inherent precision of every operation even better than I do, even more improvements would be possible.

    Supporting waypoints, and rlative positioning is the next step, and any small device with some form of serial port (be it a real one, serial over USB, Serial over bluetooth, etc) can provide this level of functionality, most would have absolutely no problems providing very coarse grain maps. (Edges of states/countires showing up, etc). But for many uses much higher resolution is desired. At the very least, high resolution mapping is desired. In some cases, like the Google Earth applications, even areal photos are useful. (I strongly suspect that a phone with with GPS and Google Earth are far more useful for some off-road activities than traditional GPS units are, at least if network connectivity is available. Data about roads and speed limits, etc are just no of that much use.)

    But for vehicle navigation, full mapping data with roads and connection information, and many waypoints for things like gas stations, and resaurants are almost essential. And those are fairly large. Not many devices can natively fit a full data set, and manufactures long ago realized that requiring users to download up to 3 out of ten regions at a time, or similar is just crap. One option then is streaming data over the internet.

      Now Full mapping data for a country like the United States fits well on an SD card, and I suspect using an SDHC card, full mapping data for the EU+(Switzerland) could be put on a card. I know that Garmin devices in theory can support having full mapping data for the planet split between the build-in memory and the SD card, if the SD card was large enough, and the owner was willing to pay for all the maps. Garmin even sells maps on SD card (Writable SD cards, not the rarer SD-ROM cards that are possible but virtually never seen.)

    Very true. Let's look back at the Nintendo Handhelds from the beginning.

    Game and watch. Simple, but they played only one game.

    Gameboy. A reasonably versatile little platform. It was not as powerful as some rivals, with only mono speaker (but stereo headphone support), had only four shades of grey on the screen, and required four AA bateries.

    Next up we had the Gameboy pocket. Based on the next generation of circuit components, this was much smaller than its predecessor, and provided similar battery life using only 2 AA batteries, but was otherwise similar. There was no reason to upgrade existing Gameboys unless the changes interested you. To the best of my knowledge it was not possible for a game to detect the difference between the two in any supported manner (although information may have leaked from some timing edge cases.)

    The Gameboy lite was an interesting upgrade that came next, but was japan only. Once again from the game side, this was identical to the original gameboy.

    The Gameboy Color was the first one different from game's perspective. This one would be a necessary upgrade to play some of the latest games, but had perfect backwards compatibility, and supported games that would run on the original with additional pallet information or even additional features on the GBC. The full feature set was available in GBC only games. In theory, a color/regular cart could have used all the GBC's features when available, but only a subset was used, specifically, double speed mode and full set of pallets was not used, as those could not be used with only simple branching to skip the GBC only parts on the original GB, so code path duplication would be needed. Also any well made GBC only game would still run on the original GB, if you could get in in the cartirdge slot, but would simply display a warning that the game was GBC only.

    Nobody complained about the GBC too much, because it was a definite upgrade from the old system.

    Next we got the GBA. Once again a definite upgrade so there were few complaints, although the backwards compatibility was a bit less then it could have been, with a few games having small issues, and the lack of the GBC's IR port. The shoulder buttons, larger screen, and significant processor improvements made this a much better machine than its predecessors.

    We get the GBA-SP. The biggest complaints here were about some flaws in the GBA-SP itself, like no headphone port without adapter. It was completely compatible with the GBA, and the difference could not be detected in software. People generally did not complain because there was no reason to upgrade unless you wanted the light, or built-in rechargable battery. The old ones worked just fine for everything.

    --------------------

    Now we reach the end of the traditional upgrades where there were few to no complaints. most were either optional, being indistinguishable from software, or were significant improvements. Backwards campatibility was lacking a bit, in a few spots, but only with a really small number of games, or if

    We get the DS. This is introduced as a third prong, and dropped backwards compatibility with everything but the Gameboy Advanced. The GBA games had pretty good compatibilily, but slightly worse than the GBC->GBA transition, and the lack of support for link cables was a real killer. So it should not be viewed as a GBA replacement, but a new console with the possibilty to play some old games, communicate with old games though editing the game's savefiles, or use the second port for expansions.

    The DS-lite came out, to only limited complaints, most about the GBA carts and accessories sticking out. It was fully compatible with the existing DS in both directions

By default it assumed that void* pointers where not available, so it used char* pointers, unless a specific #define was used, in which case some but not all of the erroneous char*'s were converted to void*. It made incorrect assumptions about what header files included a function (relying on header files implicitly including other header files when they are not required to), in some cases, bypassed including header files, and just added extern function declarations. Since this was K&R C the function declarations (prototypes) did not list the arguments, but they still managed to use return types different from those specified in POSIX. And in a few cases, the arguments passed were of the wrong type because apparently they were specified differently in early UNIX.

    That is not counting the places where a function returned a local array, rather than a copy of the array. (In fairness, the author did comment this asking if it should have been returning a copy instead.

This just goes to show that porting can be a real pain, and end users should not be required to compile programs themselves. Now, locally compiling programs can be a valid install strategy, as seen in Gentoo, but a ported must have checked on each targeted platform that the code compiles as-is, or provided patches if needed.

Producers often completely lack the rights to authorize sites like Hulu to show content outside the US, since they sold those rights already. Back when these sorts of deals first came out, this was because the producer would find it very difficult to negotiate broadcast agreements with channels overseas. There were just too many, with language barriers, and limited communication speeds. Under such a system both parties had something to gain. The regional rights holder could negotiate broadcast agreements with much more ease, and get profit through this. The production company would get revenue from overseas broadcasts which woiuld otherwise simply not not occur.

    The model has become so entrenched, that I'm not sure that a production company could possibly keep enough rights to authorize international streaming, while still getting the shows aired overseas, since channels overseas are used to dealing with local rights holding companies when negotiating for broadcast rights, and would be reluctant to negotiate the rights directly with the producers, if they even are allowed to, by the contracts they have with the local rights holding companies. In this day and age, it is far more feasible for a producer to directly negotiate broadcast rights with overseas channels, so the benefit to them of the international rights holders have diminished greatly, but they are still around.
