        Because they have the money to fund the studies. Now, whether or not that implies the studies are biased I can't say because I don't know the authors of these studies.

        BTW, if Microsoft funded a study that concluded that Windows wasn't superior for a certain task do you think they would allow it to be published? I think not. Because of that all Microsoft funded studies (that we read) will always conclude Windows is the best.

        • whether or not that implies the studies are biased

          No, we can't say positively.

          The natural forces of the marketplace, however, suggest that such studies would become biased.

      Okay, a lot of pro-Linux studies have their own problems (frankly, I don't put much stock in "studies" any more, especially vendor-funded ones).

      However, the numbers this one used are *ridiculous*. Total Cost of Development?

      Okay, let's see. Of the parties surveyed, cancelled Linux projects cost more than CE projects. This Jerry guy (he's got a PhD, so he must just be dishonest, not stupid) then uses this as a basis to claim that Linux is more expensive than CE. He's got to be kidding me.

      By the same metric, all C++ software should be replaced by bash equivalents. Why? Because the average cost of a bash-based project is much, much smaller than the average cost of a C++ project. Of course, there's the little additional detail that the sort of projects one uses bash on are much, much smaller and simpler. That is, of course, the factor that makes the huge difference. However, you can conveniently ignore that tidbit.

      Somebody tried to do the same study with Windows and some Sun servers back in the day to show that Windows made a far cheaper server. Well...yes, but most of the servers being used to average out Windows cost in the study were small, departmental servers that nobody was spending much on. The Sun servers were the far more powerful and capable systems for things like eBay's back end that had technicians swarming all over 'em. Sure enough, the Windows boxes had a lower average maintenance cost.

      Average total cost is *totally useless* without some additional constraints so that you're measuring average cost of *similar projects*. If you took all PVRs with roughly equivalent feature sets and examined cost based on embedded OS, *then* you might have a useful study. The current one is totally useless other than for FUD use.

      Perhaps, but in this case the methodology is flawed, and one needs to read no further than the first several paragraphs to see this.

      As clearly point out in the rebuttal, this was a statistical study and as such must follow precise rules to considered valid. First, any sample must be random. The study was not random but self-selective as the names were drawn from a web site registry. Second, the poll question must be made public to insure that they were not leading. Without these two criteria met, we must assume that survey is flawed.

      The problems mount when one reads that the data analysis methodology is not given. We can in fact live without know the specific data, but without the methods we must assume that the analyst crunched the data until they discovered the answer they wanted. This is a classic method of lying with statistics.

      The nail in the coffin, even if we assume the analysts are honest in all other respects, is that we do not know how the result were normalized. All we know is that for the projects developed by the Linux people cost four times as much as the projects developed by the windows developers. Were the Linux projects 4 times as hard? Did the Linux projects return four times the revenue? Were the Linux projects more costly research based projects while the Windows projects merely applications of work already completed? Were the differences in the way the various companies costed the projects.

      All the other stuff is just in the rebuttal is just a rational of why Linux development is probably just as good as Windows development. The fact is that the study has all the classic signs of a mercenary statistician massaging data to generate a predetermined answer. People wonder why kids are so stupid now. It is because companies like MS want to keep them stupid so they will believe these bogus studies.

        I didn't catch the original, and I don't know where it was publicized or anything, but I imagine it was in places that make it look legit. More importantly, it was in places that people who don't already use Linux might be likely to look. Rebuttals like this are nearly useless unless they are prominently placed in some widely read medium--and by "widely read" I mean someplace that at least an average techie, even if entirely M$-biased, would be likely to at least see the headline. I admit that I have no knowledge at all of the world of journalism, online or otherwise, but I think that people who write studies/rebuttals/articles/etc like this, showing up Microsoft and their precious status quo, should make significant efforts to get them in mainstream media.

        Unless someone already likes Linux, they're not likely to frequent LinuxDevices.com. Someone who already likes Linux is not the target audience for such journalism, or shouldn't be. We need to target it at the others, the people who don't like Linux, because it's articles like this that might make them like it, and it's studies like the one it's rebutting that make them not like it.

      I don't know what Windows version you're talking about here, but it most certainly is NOT recent Windows XP Embedded (as in Embedded XP SP1 - I assume you're sufficiently on-topic to be talking about embedded Windows stuff).

Module inter-dependencies are handled automatically, and the size of the target image easily available. You could argue that MS would need that tool, since no-one can figure out how their dependencies work anyway (and I'd agree with you :-), but that's besides the point. The point is that it's SOOOO easy to select/unselect options.

It's obvious for one if MS funded the study, it's bound to be swayed, however if they didn't fund the study, depending on the vendors, it's still bound to be swayed. Remember MS violated antitrust forcing companies to go MS or go to bankruptcy court. How is one supposed to believe any studies they'd do?

    First, let me be honest. I just skimmed the LinuxDevices article and didn't read the Microsoft article.

    One thing I've noticed among PHBs is an ever-broadening definition of "embedded systems". I've seen more than one project go down the road of using a cPCI [picmg.org] system running Windows NT 3.51 (yes these are current systems running this old version) on a harddrive. These systems are calling themselves "embedded".

    This has been especially in systems that had serious size, weight, and power needs. Had I designed the system, I guess I would've used something like QNX [qnx.com] or Linux [linux.org] on a much smaller processor, compact flash card, etc.

    I guess my point is that these days it seems like general-purpose computers are being called "embedded" when I see embedded as much, much smaller (e.g. no moving parts, a microcontroller, etc...).

    I dunno, I'm rambling...

    • need not be multitasking. That rules out a lot of the above.

      Otherwise, embedded to marketing types just means "end-user doesn't administer, except for maybe a complete re-flash". ...which is probably a more useful definition when considering the end purpose.

      But I understand a purely embedded OS is the kind that is purely reactionary, and just ties hardware together with minimal logic (hence the non-multitasking aspect, robust interrupt handling aside)

      An embedded system is generally taken to be a specific-use system. It's not small, just specific, like your car's computer is not for running office. Embedded means not general purpose (desktop/laptop/PDA/etc.). You can put a two gigahertz processor in a mars rover, but it'll still be an embedded system.

      The theory is, if you make a system that can barely do the task you need it to, then you will have the cheapest system possible. This is true in some instances, but not all. If you live alone, you prob

    On a consumer level, there are no real benefits to using Windows on embedded controllers, or even developing for evaluation boards.

    Although I deviate from Linux in this example, it is still relevant to all open source embedded solutions. A few questions: is there an implementation of Remote Terminal Services for embedded versions of Windows, for easy manipulation of the embedded device in question? If so, what sort of licensing costs are implied?

    As demonstrated numerous times before, open standards such as VNC are superior in the aspects of platform-ubiquity, openness, freeness, and simplicity. A shining example of what would be a costly, if implemented, solution, under Windows would be the Ethernet board running Contiki.

    Oh yeah, and how many simultaneous threads, per-process-threads, and processes, do embedded Windows products support?

    One must also compare the existing products that can be compiled between embedded Linux and Windows. I'm willing to bet software written with POSIX in mind beats Windows.

      They'll realize this when other people actually read the article in question.

      Go ahead. Read it. Carefully. Note that nowhere in the report does it say "Linux is great" or "Linux is better".

      In fact, to quote the article,

      Consider that in most embedded software development efforts, only a small portion of time is spent on platform issues. In virtually every project I've been associated with over many years, one engineer has selected the development environment, brought it up on the target hardware, and introduced the other engineers to its use. From that point on, everyone involved is focused on the application rather than the environment. Platform issues constitute only a small proportion of the effort expended on all but the simplest cookie-cutter devices.


      Note what's said there - it doesn't really matter what platform you develop on. That's what's said there. Develop on whatever platform suits your needs.

      Still think it says Linux is better?

      It could be, as John Lettice has pointed out, that developers of larger, more innovative, products tend to choose Linux because of the control and flexibility it offers, while developers of cookie-cutter devices tend to choose Windows because of the help it provides.


      What's that? There, they're saying "Windows is better for some things!" Blasphemy? No - they are actually trying to be unbiased.

      Granted. They can't be completely unbiased. But they're trying, which is the difference.
      • Actually, they aren't trying to be unbiased. If they were, they would say "Windows is better for some things", rather than "Windows could be better for some things". In fact, they haven't done a study at all, and are therefore not qualified to claim that Linux or Windows is good for anything, let alone that one or the other is better for a particular thing. What they are saying is that the embedded market is sufficiently broad that no single study can cover it, that accurate results either way couldn't show

      For the purposes of runtime royalty comparison, only Windows CE .NET and embedded Linux will be considered.

      No reasoning, no nothing, as to why Windows XP Embedded (which a lot of the reasoning of the rest of the report was based on). Why, might one ask, would someone do this? Might it have something to do with the fact that the royalty cost for Linux is $0, the royalty cost for Windows CE (in volume) is $2.60, and the royalty cost for Windows XP Embedded is approximately $100 per system?

      Yah. OK. That's a bit like me saying I'm going to compare the reliability of Toyotas and Fords, but for the purpose of the study, only Toyota cars that don't actually run will be used.

    I'm not sure most people understand that Windows is the most widely used host operating system for developing embedded code. I haven't read the article, but I imagine the study also discussed the issue of which workstation OS was best for writing your code on.

    One reason nowadays that most embedded developers host their development on Windows is that most embedded tools publishers only make their tools available to run on Windows. Often these tools, like compilers for arcane chips, are quite specialized, so the developer is left with no choice.

    That said, I think whoever wrote the report is on crack if they think Windows is a better development environment than Linux. I have been doing embedded for a year now, and one of the main things I still dislike about it is that I have to do most of my development on Windows.

    It is quite common for each compiler vendor to write their own integrated development environment, with an editor and integrated build system. But the market for these products are not as great as the market for IDEs for the development of desktop or server software, which means they can't invest in developing a more refined GUI for their IDEs, so their basic usability and quality is quite poor.

    If you think Visual Studio is a lousy environment for development, you should try the ARM IDE or TI's Code Composer Studio. Using them is like pounding nails with your fists.

    However, the situation is slowly starting to look up. GCC targets many embedded CPUs and is starting to become widely used for embedded development. The other GNU tools also form a more or less complete set of what you would need to develop embedded products, with GDB acting as both a debugger and simulator, LD able to function as an embedded linker, being able to do two-machine debugging with GDB and so on. Also there's GNU make, CVS and so on.

    The result is that while I had to use the proprietary (and expensive) ARM compiler to develop for the Oxford Semiconductor [oxsemi.com] ARM7TDMI-based 911 FireWire/IDE bridge chip (which allows you to hook up inexpensive IDE disk drives as firewire storage), they switched over to building their firmware with GCC for the 922 USB/FireWire/IDE 922 bridge chip.

    I've been using GCC under Cygwin for my 922 development, but a CD with a new SDK on it is expected to arrive in the mail any day now. When it does, I will have a choice of Cygwin, Linux or Mac OS X development environments, all running the same version of GCC. And I'm very happy about that.

    Most likely, though, I will use Mac OS X for my 922 development. I'd prefer using Linux to Windows, but if I can use Mac OS X, I'd prefer that to Linux, if for no other reason than the fact that the clipboard works correctly [slashdot.org], as well as that I could use CodeWarrior [metrowerks.com] to edit my source.

    Maybe if I get real ambitious, I might write a CodeWarrior plugin so I can use the CodeWarrior IDE to compile my code with arm-elf-gcc.

    (And don't give me crap about not using Emacs. I was an expert at Emacs when most of you were still in diapers. I still have my .emacs file which I first created in 1987. But I vastly prefer CodeWarrior's GUI text editor unless I have some reason to run a bunch of Emacs lisp code on my source file.)
