Ask the Author of the Latest MS-Funded Windows vs. Linux Study 449

Last week on Slashdot you saw a (Microsoft-funded) research study on Windows vs. (Novell) Linux reliability by Dr.Herbert Thompson. Novell disagreed with the study's conclusions. So did most Slashdot readers. Thompson's work been mentioned on Slashdot before, especially his famous five-line script that could change electronic voting machine results and his novel, The Mezonic Agenda: Hacking the Presidency. He's a real, genuine-article computer security expert (and regular Slashdot reader) who is happy to put on his flame-resistant suit and discuss his Microsoft vs. Linux study with you. So ask whatever you like, one question per post. We'll send him 10 of the highest-moderated questions and publish his answers next Monday. He'll jump into the discussion then, which ought to make it rather lively.

    Dr. Thompson:

    Admittedly, I don't know who you are and I haven't read any of your books. Worse, I didn't read your study itself, only its conclusions as reported second-hand by the press. However my lack of knowledge of your backgound is probably consistant with most Slashdot readers and the IT industry as a whole. I have to give you the benefit of the doubt and assume that you are a capable, respected researcher elsewise MS wouldn't have approached you in the first place.

    Could you please explain why you decided to risk drawing your objectivity into question by undertaking this project? Your findings may be 100% valid. And MS may very well have straight-up told you: "Please print whatever you find, even if it casts Windows in a bad light." However, who's going to believe it, even if it were true? If I were in your shoes, I'd be affraid that making a deal like this would ruin my career. If I don't tell MS what they want to hear, word would get out that I don't play ball. If I do report what's in the sponsor's best interest, a lot of people start accusing me of being a shill. Seems like a lose-lose proposition.

      Good question. I'd be scared to post anything pro-microsoft on here, as a large number of /. users are pro-linux and anti-microsoft. I myself, am not too biased one way or another. I believe at this time that both linux and windows have their places, and aren't in 100% direct competition.

        What many of you miss to realize(Microsoft included), is that there are a large group of current Microsoft only customers that are unhappy with their current offerings. Just because someone is against Microsofts decisions doesnt meen they like Linux. Many just see Linux as a catalysator wich will free the market, push standards and make interopability more common between vendors. Its very rare with 100% Microsofts network still Microsoft refuses to support any standard that would make life for their customers easier. The constant steering towards 100% MS networks is pissing people off.

        This really isnt about Linux its about making computers and their software be as standard as the internet.

        Is a Linux study funded by GNU/FSF/OSI/OSDL or whatever any more impartial? No.

        I think many here would disagree. Nonprofits are not driven by motives which could be considered the mirrored opposite of commercial corporations. There is not the tremendous pressure to turn a profit (or some analog to monetary gain), and in your examples they're run by mere handfuls of individuals receiving very little compensation with only their reputations to fall back on. They represent what are largely hobbyists, almost to a maddening degree.

        OTOH, in Microsoft we have a callow and selfish for-profit entity with a rather abusive track record right up through their financial, er, daliances with SCO.

        Need I say more?

        Given their dynamics and history, being so dismissive of FOSS organizations as to just say 'well, eveone's biased anyway' really doesn't seem like an acceptable attitude.

          I think many here would disagree.

          Hang on, you're saying you believe that you would trust a FSF or OSDL-funded study to be impartial? You're saying that if the FSF funded a study comparing GNU to Windows, and the study came back saying "Windows saves you money in the long term, and Microsoft's Shared Source is as good as Free Software for 99% of users", that the FSF would then be happy to publish that study?

          I don't think so, and I suspect you won't either, if you pause to think about it.

          Nonprofits are not driven by motives which could be considered the mirrored opposite of commercial corporations. There is not the tremendous pressure to turn a profit (or some analog to monetary gain), and in your examples they're run by mere handfuls of individuals receiving very little compensation with only their reputations to fall back on.

          But that doesn't make them impartial! All it means is that the profit motive is replaced by other motives. And there are plenty.

          Think about how much time the major contributors to free software projects put into those projects. Hours, days, months, years of personal time, freely given. Time that could have been spent earning money, or doing charitable work, or even just spending time with their families. Time that was wasted, if it turns out that the software they produced is not actually going to help many people do anything at all.

          When you reach middle age, and the end starts to heave into sight on the horizon of your life, you start to get very, very uncomfortable about the idea that you might have devoted your precious time to an unworthy cause.

          Being so dismissive of FOSS organizations as to just say 'well, eveone's biased anyway' really doesn't seem like an acceptable attitude.

          What's dismissive about that? Microsoft really does think that everyone ought to use Microsoft software, and the FSF really does think that everyone ought to use free software. Everyone is biased. Pretty much everyone does have a pre-existing investment, either of time or money, in one of the options. And human nature does dictate that when you have an investment in something, you are biased towards accepting studies that support it and disregarding studies that don't.

          What's wrong with telling the truth?
          • There's a number of huge distinctions between the open source community, such as the FSF, and Microsoft. One of them is money: the other is that Microsoft has been caught tiime and time again lying in court, under oath, and breaking the clearest laws of intellectual property ownership, trade secret theft, coercion of witnesses, and fraud.

            The FSF keeps its nose squeaky clean, because they know they have to to keep any respect from their members and from the world at large.

          • When you reach middle age, and the end starts to heave into sight on the horizon of your life, you start to get very, very uncomfortable about the idea that you might have devoted your precious time to an unworthy cause.

            Which is supportive evidence that your argument is too biased in itself to consider.

            How is helping to produce freely given and very secure software for EVERYONE ELSE TO USE FREELY an unworthy cause? Indeed, one could (and I do) consider it "charitable work".

      Corrected. I know it may seem like a troll, but I don't think it is. Something that a lot of the readers of this site don't understand is that not everyone thinks that Linux is the shit to the point of denying all evidence to the contrary. Don't get me wrong, I have one Linux-only computer that I use for work, my other is dual boot, and I like it. I love Linux both for its principles and because it allows me to do things that I can't normally do with Windows, BUT that does not mean that I believe its raw performance to be equal to that of a more heavily funded operating system. And you know what? That's OK. I'd still rather use it.

    The study seemed to only compare comercial applications on the various platforms and not the alternatives. Its very common that comercial apps on Linux have poor support on Linux while the free alternatives blows most out of the water on Windows too. Its not especially hard to select a couple of apps with stellar support on Windows and SAP like support on Linux and blame Linux when the problem really lies in the lack of vendor support. Some vendors even support just one specific linux version without! any patches applied.

    What care was taken in selecting applications with similar support offerings to not bias the study heavily to Microsofts advantage?

          Sorry, ddd/gdb, Eclipse, and so forth are pale shadows to MS Visual Studio still, particularly for C and C++ work (Eclipse is probably the best for Java though).

          Our code is cross platform Unix, but we maintain a Windows port for one reason only -- debugging. Using Visual Studio is far, far better than the alternatives. We vastly reduce the time involved in finding and eliminating bugs by doing so. And no, we don't sell the Windows version. It's literally only used for internal debugging.

          Is there a technical reason why the Linux debuggers couldn't be better? Of course not. That's completely and utterly irrelevant (as are most of your "explanations" you attempt to give in rebuttal) though. The fact of the matter is they aren't, and are actually several years behind in comparison.

          And no, I don't develop in Visual Studio -- I prefer vim. And we use CVS for source control. We use gmake (even on Windows) and other OSS tools too. Best tool for the job.

    If scaling up on windows means significant reliability issues, how has google managed to avoid these despite scaling to the level they have?

    Or Amazon, which I beleive also runs on linux. These are true enterprise level e-commerce apps, and despite the tons of studies saying they've picked the WRONG computing platform, places like google, amazon have amanged to create profitable businesses on non MS platforms.

    Lately, I've felt that Microsoft is emphasizing greater trust in their control over your system as a means of increasing your security. This is suggested by the difficulty of obtaining individual or bulk security patches from their website as opposed to simply loading Internet Explorer and using their Windows Update service, the encouragement in Service Pack 2 of allowing Automatic Update to run in the background, and the introduction of Genuine Advantage requiring the user to authenticate his system before obtaining critical updates such as DirectX.

    In addition, Digital Rights Management or other copy protection schemes are becoming increasingly demanding and insidious, whether by uniquely identifying and reporting on user activity, intentionally restricting functionality, and even introducing new security issues (the most recent flap involves copy protection software on Sony CDs that not only hides content from the user but permits viruses to take advantage of this feature.)

    I would like to know how you feel about the shift of control over the personal computer from the person to the software manufacturers -- is it right, and do we gain more than we're losing in privacy and security?

    The Linux administrators faced some out of the ordinary challenges, not faced by most Linux admins, while the Windows admins faced none.

    For example, most of the time difference between Windows and Linux was spent upgrading gLibC, something that you're really not supposed to do. It's comparable to trying to manually upgrade parts of a Windows 98 system to run a program that required XP, rather than actually upgrading to XP.

    Then, you had the Linux admins getting updates from 4 different sources, rather than just from SuSE's repositories, which is also out of the ordinary, while the Windows admins only visited Windows Update, which only supplies patches to the base operating system, when in reality they'll have to get updates from many other sources if they wanted to keep their apps up to date.

    Do you think this was a fair study?
    • The glibc upgrade was if i understood it correctly done instead of just compiling MySQL manually. I was boggled, why would you change glibc instead of making a fast compile? Upgrading glibc will make the whole OS and all its applications unstable, its almost as it was intentional. I have a hard time beleiving a seasoned linuxadmin would do such a stupid thing as upgrading glibc.

      Its smells funny indeed.

    I haven't had time to read through this study in its entirety, but from what I have seen it looks like there are several things that could lead it to improper conclusions. First, some of the procedures used to define the benchmarks seem completely arbitrary. For example, security fixes are applied on a monthly basis, rather than as they become available and can be tested, or based upon their severity. In my experience some security patches are tested and applied immediately and others are applied later. Also, no mention is made of mitigating the effects of security vulnerabilities/exploits before a patch is available which, while uncommon does happen. Coincidentally, Microsoft has moved Windows to a monthly patch release cycle. Don't you think defining the operating procedures to be exactly those used by one OS, and not the other biases the test?

    Another concern I have is that while your study simulates the installation and upgrade of two different systems based upon two OS's, it does not seem to simulate the real-world work needed to keep those systems running on a daily basis. In the real world systems break, worms clog the network, and regular maintenance must be done. Your study seems to completely disregard all that work and focus only on install/upgrade. Why did you not base your study on the behaviors of a real working system with a simulated network attached? It seems like the shortcut method you used to quickly evaluate only certain tasks makes the study wholly academic and loses any value as a predictor for the operation of a real network, over time, with real traffic.

    Finally, I've seen it suggested that this study requires that all software be updated to the latest versions, but While Linux based servers constantly release the latest patches to each component as they become available, Windows only releases them en masse, How then can you compare the two? To be perfectly fair one would have to know what development has happened on the various components of Windows and rate all of those components as failing to be updated (since MS has not yet released that version). Barring such inside information, any comparison between a system with an open development process and one with a closed development process is critically flawed. Do you not see this as a problem with your study?

    I wonder if it's really appropriate to make TCO guesstimates from a study which essentialy asks the question "Which OS has nicer installers?"

    From the study:
    We conducted an experiment pitting Windows 2000 Server against SuSE Linux
    Enterprise Server 8, simulating [a] one year period...At the end
    of the period, both systems are then transitioned to the more recent versions of their
    respective operating systems, Windows Server 2003 and SuSE Linux Enterprise Server 9.

    What I find lacking is the business case for upgrading the OS. And why on earth would any enterprise with even the tiniest amount of foresight and planning deploy Windows 2000/SuSE 8 knowing they will upgrade to the next gen just one year later? (Not that there aren't plenty of enterprises who fit your model, not to mention IT workers seeking to "power level" their skills...)

    Now, certainly there is value in trouble-free installs. But can you say with confidence a better upgrade experience is really a fair test of value? Especially when the entire install/patch/upgrade philosophy between Windows and Linux is so disparate?

    In other words: It's no surprise that Windows will perform better on the treadmill, constantly upgrading is at the very core of Microsoft's profitability.

    If I understand the study correctly, the windows side had to do nothing but set up a server to do a few different tasks over time and run windows update. The linux side had to have have multiple incompatible versions of their database server running simultaneously on a single system and had to run unsupported versions of software to do it.

    Why wasn't the windows side required to run multiple versions of IIS or SQL server simultaneously? In real life if you need to run multiple database versions you use virtualization or multiple systems, especially if one requires untested software. You don't run some hokie unstable branch on the same system as everything else. Why was a linux solution picked that required this level of work? My other related question is, did any of the unix administrators question why there were being asked to do such a thing? For example, did they come back and say they need a license for vmware? If they did not they do not seem like very competent administrators in my opinion.

    1. Windows administrators are forced to wait until Windows releases a patch for known vulnerabilities to upgrade their systems. Why, then, were the Linux administrators told to attempt to upgrade their systems before Novell had released newly packaged versions of MySQL? The entire point of a package management system is that administrators rely on companies like Novell to correct dependencies prior to deployment. Since Windows administrators have the same constraint (i.e., waiting for security updates to be released), it is an unfair and arbitrary difference that caused a lot of troubles.

    2. Why did you compare the number of patches required to apply between the systems? This is not a measure of security. Windows patches are bundled and affect many parts of the operating system while Linux patches affect individual components. The overtone in your paper implied that fewer windows patches was in some way easier or more secure; what justification do you have for this assertation?

    3. While kernel patches did not require an immediate reboot during installation, the majority of them need a system restart to immunize the system against a specific vulnerability.

      -Page 25, under "Patching and Milestone Upgrades"

      What is the rationale behind this? Were the Linux administrators required to restart at this point? This is an incredibly contrived situation; one can simply stop and re-start the process in question after the upgrade has completed.

    4. Furthermore, the upgrade methodology questionable. Real companies use development and production servers and don't upgrade the production server until a reproduceable upgrade trajectory has been tested on the development server. The actions of these administrators imply that they had no such access, and that there was no possibility for backtracking or restarting after a failed step. Normally, one would expect the ability to nuke the development server and start over, rather than following a bad plan to worse conclusions.

    A quick read of the report shows that the real losers here seem to be the Administrators. Some of the Linux admins "could not meet business requirements", and some were judged as failures by not using vendor-supplied solutions.
    Isn't one of the points of running Linux servers the freedom to use solutions NOT supplied by the vendor? Is it even possible for the Microsoft admins to make changes that aren't fed from the vendor?
    When the only tool you have is the "Upgrade" button, and the button doesn't work, what then? The advantage of Linux in administration is the flexibility to Make It Happen, even if the vendor sends you something broken.
    I know good admins on Microsoft, and good ones on UNIX. They seem to Make It Happen no matter what, because that is their job. Making It Happen sometimes include custom fixes, that are documented, so you can undo them when the vendor comes through (hopefully) later.
    So the Final Question is, why was it bad for the Linux admins to stray from vendor-supplied fixes, and why is the lack of flexibility on the Microsoft side a "win"?

    Dr. Thompson, the way you selected the administrators seems to suggest a strong bias against Linux. In Appendix 3 (page 41), you recruited Windows administrators with at least 4-5 years of Windows administrator experience, while in Appendix 4 (page 43), you recruited Linux administators with just 2 years of Linux experience.

    It seems that either you're a true Linux believer thinking that a Linux administrator can out-smart, out-perform a Windows administor with twice the experience, or that your experiment was setup to pit inexperienced Linux admins against experienced Windows admins.

    So far as I can tell, the essence of your study, and your conclusions rests on the following assumptions:
    1. The set of requirements listed is a natrual one.
    2. The schedule is a normal business schedule.
    3. The method by which the components were selected, ordered, and applied was natural.

    You state in your report that the requirements were developed after interviews with "leading CIO's, CTO's, ..." Nowhere do you state who conducted those interviews and, crucially, how many of them had overlapping requirements. Similarly, you do not state how you selected the particular schedule of your study both in terms of the product-period that you examined and the feature schedule you considered.

    Moreover, in appendix 5 of your study you show little overlap between the lists of popular component users. Many of the groups listed for one "popular solution" were not listed on another. Nor did you separate these lists by operating system. This give no indication whether the popular components are ever used in concert. Nor does it indicate how many groups are using each feature set or system. Nor even where these user numbers came from.

    I bring these points up because they point to potential holes in your study that I am curious about. In particular:
    1. If either Microsoft or Novell supplied either the requirements list and/or the upgrade schedule then the study is vulnerable to the assertion that they schose a schedule, time, etc that was most favorable to them.
    2. If the most popular 'component' solution to any one task is used only by one group but not another then this may point to general incompatibilities between them. When making a purchasing decision I typically consider the current state of my system and potential compatibilities with future upgrades. If the components selected for either os are not typically used in concert then this raises the possiblity that the components have known incompatabilities that would keep them from being used together. In that event the system administrators would be installing packages that are not meant to go together and would not be selected by a real-world selection metric, and as a result faced unrealistic issues.
    3. In your selection of "popular components" you focused on 3rd party solutions. Nowhere do you state whether you considered only commercial vendors of such solutions or open-source vendors as well. If you focused soley on commercial products that might mean that the system administrators were actually installing less popular, or less viable products on the linux side given the lower amount of such vendors for the Linux platform.
    4. If the schedule of upgrades was not one used by many of the real world companies but again, an artificial one constructed as a superset, then the study is vulnerable to the charge that it used an unrealistic technical schedule for installing and testing components.

    My question is, do you see these as issues? If not why not?
