            Wine emulates the Win32 API, if anything

            Wine does not emulate a processor, video, or sound subsystem, but rather 'wraps' the necessary calls (in theory) to native Linux calls. It requires an x86 CPU (for which an x86 emulator could be used, I suppose, but it's still not part of Wine).

            And in the situations where real Win32 DLLs are used, it's not even emulating that part of the API.

            It might be considered a simulator, but I doubt it would be considered an emulator.
          • Then it is obvious that you don't know what an emulator is.

            WINE is an implementation of the win32 api on linux, such that windows applications will run on it without recompiling. An application running on WINE isn't encapsulated in a "safe" emulated environment much like vmware would do, it's running in your system just like any other app you're running.

      Yes, it is a solution. Especially in situations where you have persuaded your friends and relatives to use Linux, but they still want to use some crappy Windows software because they are used to it, and there are no free/open-source ones.

      Furthermore, the 2% of Linux users don't really constitute a meaningful profit motive for these companies. We need to do more to get Linux on the desktop before they'll jump off the MS ship.

      It's simple. A lot of specialty software is very boring, and there just isn't any interest in the OSS community in developing similar software.

      Many businesses, especially real estate, banking, auto repair, fast food, and hotel management, rely on software written for windows many years ago that, for them, functions just fine.

      They're not techies: computers are not their business. Their business is their business. They're not going to invest resources in developing what they already have just so it can run on "another kind of computer." WINE is the perfect solution for these applications.

      Maybe, years from now, when they're running -ALL- of their software under WINE, they might realize that there's a better way.

      Until then, good luck finding good programmers who are psyched to write hotel reservation management software that will interface an archaic database platform for free.

      Projects like Open Office and The GIMP don't suffer from this problem largely because they're applications that Linux users need on a regular basis. When was the last time you needed to track your fast food orders?

      I used to work for a 5-person company. We easily ported our main ap to linux, but a critical tool we used to build our code was developed for windows. It was gui-centric, so a port would be difficult, and besides, all the programmers were algorithm people, not gui people. Wine was a godsend - our old tool just worked, and it saved us a lot of time. Boycotting ourselves wouldn't have gotten us the needed people to port it.
    • If we can prove that their programs can run well under linux with just a few tweaks in how it speaks to the system (WINE [wikipedia.org] is a compatibility layer [wikipedia.org]), and possibly even explain to the company how to change their software to speak correctly, it makes it take a lot less of their time to release a native linux version, as they already know how to do it.

      So if you help them help you, we've got native software on Linux. But, that's just my opinion.

    This past December, one of the engineers at my workplace gave a presentation on WINE. Since I'm the security guy, somone asked me if Windows viruses ran under WINE. So I tried three: Lovgate, a Mydoom variant, and a Netsky variant.

    Lovgate simply exited without doing anything. Mydoom actually crashed WINE into its debugger. The Netsky variant, as the article describes (SomeFool is Netsky) actually ran. Moreover, it did a passel of DNS queries and actually tried to send e-mail (which was rejected). So, if that e-mail had been accepted, Netsky would have been able to propagate under WINE. As in the article, Ctrl-C proved necessary and effective.

    To make a long story short, yes, some Windows viruses do run under WINE. Of course, you have to tell WINE to run them -- not exactly the social engineering that viruses are intended to do. However, as WINE gets more popular and reliable, I would expect that this will be more of a problem for people who choose to (e.g.) run Outlook in WINE.

    (For what it's worth, WINE isn't the only way to run Windows viruses and worms on your non-Windows system. I've had to explain to users that yes, their VMware or Virtual PC system is quite capable of getting wormed, and that yes, they did need to do their Windows Update on that "virtual" Windows system, too.)

    • Of course, you have to tell WINE to run them -- not exactly the social engineering that viruses are intended to do.

      You can tell Mozilla to open .exe's with Wine ;-). Maybe you can add the same mime-types to Gnome and/or KDE!
    • There's no need for social engineering. I remember on Red Hat 7.3, Windows .exe files were automatically launched with Wine under Gnome. Which meant that attachment viruses could be run from Evolution by clicking on the attachment.

      I never tested to see if they worked, but then I never really wanted to find out!

After I logged in, I noticed that my desktop menu had a lot of strange, poorly documented programs in it, some of which didn't seem to do anything useful. The configuration system was strangely flakey, popping up tabbed windows that wouldn't go away when I clicked on other options. Various programs worked partially, but in some of them the clipboard didn't work properly and in others the windows widgets and controls looked wrong. A few would randomly open shell windows when I tried running them, even though they were GUI programs. The windows theming/skinning system worked partially, at best. I tried running a graphics program, but it just opened up lots of windows all over the screen and I couldn't get it to do anything reasonable, so I gave up. I suspect it was the cause of the virus infection, in fact, because it was called some insulting and childish name that had nothing to do with Graphics or Image Manipulation Programs or anything else. Oh, and there's this picture that shows up everywhere, of some kind of anatomically improbable cartoon bird with an eating disorder, which is either a symptom of virus infection or else a failed attempt at coordinated branding by a lot of uncoordinated programmers.
