    Do I need to explain the concept of "Goodwill" yet again? Why do people keep this shit up? Are they holding short positions in RHAT?

    Goodwill is the amount of money a company pays for another company, that is above the value of the tangible assets of the aquired company. This may include brand names, patents, and other intangibles. If a company buys a company that turns out to be overpriced later on, then the buying company will have lots and lots of goodwill that must eventually be charged against earnings.

    Red Hat did not lose those large amounts of "real assets", rather, almost all of that "loss" was a write down of goodwill from previous aqusitions.

    Look at it this way.

    1) RHAT IPOs
    2) RHAT stock becomes grossly overvalued
    3) RHAT makes a secondary offering, cashing in on their grossly overvalued stock in a big way.
    4) RHAT goes on a buying spree, spending their money that they got for free, buying companies like Cygnus.
    5) Cygnus was also pretty overvalued, so a lot of goodwill ends up in the "assets" column of RHATs balance sheet.
    6) RHAT has to write off chunks of this goodwill against earnings later on.

    The key is that RHAT got this money for free. Had they not made the secondary offering, they wouldn't have had the money to make the aqusitions in the first place. Sure, that money ultimately came from idiot investors that paid $200 a share for RHAT, but it didn't come from any direct business or financing activities that had an opportunity cost for RHAT (such as debt financing).

    So no, they aren't losing those staggering numbers each quarter, in fact they are breaking even for the last 3 quarters or so.

    Goowill can be abused. "One-time-charges" can be abused (see Cisco writing off billions of real, tangible, inventory).... but in this case... there is no money lost, just worthless monopoly money that no longer exists, and hasn't existed for years, subtracted from a column on a balance sheet.

      RHAT did dissapoint in the most recent quarter, they broke even again when it was expected that they would have at least a modest profit by now.

Open Source is non-differentiating for your business, because everybody else can offer the same thing, and thus the best plan a business can have for it is to use it to reduce cost so that they can spend more on their differentiators and profit centers.

    In making a business plan, you will need to figure out what your differentiators and profit centers will be. It's obviously not going to be software sales - the folks who tried a royalty-based embedded system based on Linux went out of business faster, because they had free competition. In general it will be consulting services, and this is going to be a difficult business in a slow economy as businesses will try to do more with their own engineers. Businesses also have an incentive to use their own engineers for embedded work, as they don't want to be in the situation of losing the recipie for one of their own products.

Had I not used the GPL, he would have had to give it up when his previous employer was one of those shaken out. I have a lot more sympathy for him than the employer. Also, had I used a license other than the GPL, the program would not have become an open standard for embedded - everyone would have been making their own proprietary additions rather than cooperating. And I didn't care that companies could not lock in a revenue capture on busybox - why should I?

    I'm sorry, apparently I chose the wrong words or phrasings, since you seem to have misunderstood my message.

    The eCos kernel, the kernel that RedHat acquired when it bought Cygnus, does not have a POSIX compatible, or even unix like, kernel interface. It has a kernel interface, it just looks very different than Unix. They weren't creating an incompatible kernel just to be different, they were doing it to create a kernel with features ideally suited for the development of embedded devices.

    As an example, a separate thread of execution is not started with fork() or pthread_create(), but rather a thread is created with cyg_thread_create() or sta_tsk() if the ITRON API is built into the kernel. If you look at the eCos API and something with a Unix or POSIX API you will notice that few if any of the same calls exist on the two platforms. Just to reiterate, so I'm not confusing you again. RedHat's eCos is a kernel designed for embedded systems and is not at all similar to the POSIX standard.

    Now QNX as a developer of of software for the embedded market took an interesting strategy. Since there is so much software written for a POSIX style kernel, and it is an API that many people are familiar with, they created a kernel small enough for embedded devices, but gave it a POSIX API. This may make some tradeoffs in many directions, since what the program needs from the kernel and what the kernel needs to inform the code is very different for embedded devices than for a desktop or server OS.

    Now to my comparison between eCos and QNX. When eCos is built with its optional EL/IX component, it starts to implement a subset of the POSIX API. So calls like read(), write(), and fcntl() are available. If you flip on the EL/IX switch, it starts getting a lot more familiar to Unix developers, which getting the product a little towards what QNX's product line does. Or at least having the same advantages.

    Unfortunately, I can't quite understand how you read what I wrote originally and picked out the two sentence fragments you quoted as being a summary. If you could point out where my original post was unclear, I can try to avoid making the same mistake in the future.

    Finally, to directly answer your points.

    • No, you are right, a kernel isn't an API, but a kernel does implement an API. eCos does implment an API, but that API (without EL/IX) is very dissimilar to POSIX.
    • Now for a company like QNX with a product like they have, I can perfectly well understand why they would participate in an effort like POSIX. As the committee is debating the pros and cons of particular features, they really want to be there to argue against features that could be construed as adding bloat.
    • Being on a committee doesn't make a vendors product more or less compatible with the standard the vendor produces.
