    I thought the problem was that Microsoft told everybody that they didn't have any patents on C# or .NET, but they are actually a licensee of somebody else who has patents on it? Miguel dodged the question on this one by simply stating that it was a reimplementation rather than licensing .NET from Microsoft.

    Listening to the audio, the things on the horizon are Windows Forms and incremental improvements (tuning). People are porting applications today, usually you can just copy the binary, but ignorant Windows developers do things like screw up path separators, assume case-insensitive systems, etc.

      I thought the problem was that Microsoft told everybody that they didn't have any patents on C# or .NET, but they are actually a licensee of somebody else who has patents on it?

      Well, let's be precise. C# and .NET are two different things.

      C# is an ECMA standard with features that are found in dozens of other languages. There is no indication that there is anything patentable about it. In fact, if you look at the C# specification, it is clear that they have been careful to avoid patents that Sun owns on Java (yes, Java is patent encumbered).

      Then there is .NET. It is a huge collection of APIs, many of them Windows specific. In a trial balloon, Microsoft has attempted to patent the totality of those APIs. What the significance of that patent is going to be isn't clear--it may not be worth the paper it is written on.

      So, what's the upshot of it all? You can't avoid the risk of patent infringement no matter what language you use. However, at this point, it is pretty clear that C# exposes you to no greater risk than other languages. As for .NET, you don't have to use it: most open source applications developed in Mono are written using the Gnome APIs, not the .NET APIs.

      It's not an ideal world, but if you want a reasonably popular and practical natively compiled language with garbage collection and reflection, your choice basically comes down to C# and Java. Java is completely owned by Sun: Sun owns the specifications, Sun holds many patents on it, and Sun effectively can control who may implement Java and who may not (they have chosen not to exercise that control vis-a-vis implementations like gcj and classpath yet, but if they want to, they can). C# may not be the ideal choice, but it's the best you are going to get.

          The real nuts-and-bolts of .NET are decidedly NOT an open standard. This is what concers many people.

          Yes, large parts of .NET are not an open standard. But it's wrong to refer to those as "the real nuts-and-bolts", which falsely suggests that Microsoft kept important portions of the low-level foundations of C# proprietary.

          ECMA C# is a complete and powerful language and set of libraries--far more complete than C or C++. Together with the open source APIs that already exist on Linux (Gtk, Gnome, etc.), it gives you a fully open and documented platform to build applications on.

          Additionally, since .NET is a wholly controlled "standard" by MS then Mono will be on the same treadmill that WINE and other groups chasing MS implementations have been on.

          Most open source Mono developers won't be affected by .NET at all because they won't be using .NET; they'll be using C# with open source APIs.

          If you choose to use .NET, for example because you are developing a Windows application that you also make available on Linux, then, of course, you are dependent on the .NET APIs, but that's because you chose to use .NET. Mono is doing the best job they can in giving you that capability, but even if they fail, it just won't make a difference to open source developers.

          Also note that Mono is in a far better situation in this regard than open source Java efforts: Sun has draconian compatibility requirements with which they may be able to shut down any open source Java project whenever they choose.

    I've tried Mono, and while I've little desire to move from Python over to Mono, it's a very well done project. The GTK bindings are quite nice, and C# as a language is much, much, much easier to work with than Java.

    The big "if" is whether or not Mono can become to popular without Microsoft trying to pull the plug. However, even if that does happen, C# is an ECMA standard. There are plenty of native Linux libraries that can be used in place of the Microsoft classes. For developing GUI applications under Linux, you're not going to use the Windows.Forms libraries anyway, you're going to use GTK. Mono can stand on its own as a good RAD language for developing graphical applications for GNOME.

    I know it's fashionable to bash MS at every turn (and as a Mac/Linux user I do all the time), but C# is a nice language and the .NET libraries are infinitely better than the cruft of Win32/MFC and the other mess of libraries that Microsoft used to shove down programmer's throats. Mono has done an excellent job of taking those libraries and making them work on Linux.

    Even without the Microsoft libraries, Mono still provides a good framework for RAD under Linux and GNOME. If we can make it as easy as possible to transition between Windows programming and Linux programming it only helps propagate Linux.

    I can perfectly understand that many hate Mono simply because of the fact that it was Microsoft who designed .NET. That is a valid argument; however, it must be considered that Mono is something that, in the future, is really required for the Linux/UNIX world.

    I suppose that those bashing Mono have never actually worked with C#. Personally, I'm really an anti-MS guy, but at work I was basically "forced" to use C#, and I must admit, it absolutely rocks. It is simply a much more productive language than C or C++, especially for GUI development. When you get a specific task, you're simply much more likely to get it done and get it stable within a given time in C#. The biggest productivity gain (besides the syntax candy, like foreach loops) comes from the garbage collection. Sure, other languages like Java have that, too. But, as far as typical DESKTOP applications are concerned, Java has failed to gain popularity both with users and developers (I suppose the major reason is that Sun took way too long to finally allow Java GUI apps to integrate themselves seemlessly in the desktop by adapting a "native" look & feel; but that's another issue).

    Linux apps have done a great job in the past years in getting competitive to their Windows counterparts. So, if Linux wants to stay competitive with Windows in the future as well, there must be a similarly productive language for GUI development on Linux. Standard C/C++ with GTK+ and QT can certainly compete with the horrors of MFC easily. But, in my opinion, not necessarily with the combination of C#/Windows.Forms, as far as speed of development is concerned.

    Also, if we want to see more commercial applications to run on Linux, there must be a way to easily develop portable GUI apps. Imagine you're the boss of a smaller software company. You develop Windows apps, your customers all use Windows (welcome to the real world!). Maybe 3% of your customers consider switching to Linux. And now you're starting that new software project that must be finished within a certain time. What are you gonna do? Buy QT, and tell your developers to start learning it? Use GTK, with all related problems on the Windows platform, and tell your developers to start learning it? Nope, that's not what the typical boss is gonna decide. He'll let the developers use what they're used to, M$ visual studio, where they can click together the GUI. He'll tell the 3% of the customers that Linux isn't supported.

    And this is exactly what may change with Mono!

    And talking about the patent issue: Giving up on Mono because of potential patent issues would mean giving up on the patent issue itself. Mono could be the best "bad" example how software patents support a monopoly and limit interoperability. The fight against software patents isn't over yet. At least not in Old Europe.

    Mono needs a bit of work to work with PaX [grsecurity.net], but it's possible. I mentioned the necessary changes [kaffe.org] to the Kaffe team; but they apply to any JIT.

    The issue is that a JIT compiler like Mono generates code at runtime. Because it's not generated in realtime (it's compiled at the loading of an executable module, one time), it's feasible to dump the executable code to a file on disk and mmap() it in.

    PaX won't allow code to be generated in memory unless the program has mprotect() restrictions off and uses mprotect() right. It's safer to rewrite the JIT compiler though, since you wind up with a stricter security policy that way.

    Furthermore, Exec Shield's NX emulation is flawed, and the use of mprotect() in those ways would disable the protections on large parts of the binary. If anything happens in or above the stack, the whole stack is likely executable. This is in fact one reason I prefer PaX; a slight modification to Red Hat's kernel to print X instead of - in /proc/[pid]/maps for !PROT_EXEC memory that's actually executable prints out a good deal of areas that are executable but shouldn't be (rwx vs rwX).

    Mono is flexible enough that C and C++ can be compiled to .NET. Microsoft supports this, as mentioned in earlier slashdot posts. It's really important to consider .NET and Mono as insecure, and to make sure they're adequately protected. If you're running all your programs in Mono and Mono has to disable PaX, then you lose the benefit of your GrSecurity-enhanced kernel. (same with ES).

    • Mono needs a bit of work to work with PaX, but it's possible. I mentioned the necessary changes to the Kaffe team; but they apply to any JIT.

      For the benefit of readers, those "necessary changes" are to require a JIT to generate shared libraries for each class that's loaded, and then dynamically load the shared libraries.

      That's fine for a JIT that is only used to generate static code for each class. But it's not efficient for dynamic optimisation techniques, such as run-time profile-driven code optimi

    The absolute major problem with the way I feel Miguel has handled the Mono situation is that he constantly refers to ".NET". It's as if he somehow thinks he's going to outsmart Microsoft or something. You can't beat Microsoft at embrace and extend, you have to change the game. .NET is a MARKETING TERM!!!!!!! Don't you remember when it originally got tacked on to every single Microsoft product? Saying Mono is an Open Source implementation of .NET is ignorant at best, and misleading and irresposible at worst. Just stick to C# and CLR and make no mention of .NET at all. Otherwise, they will continue to show me just how absolutely pathetically naive they (especially Miguel) are. .NET is basically Microsoft's brand, and Miguel will never establish authenticity, originality, etc. by latching on to a MS brand. Sure, take the best stuff, build on the shoulder of some giants, but have some !@#$ business sense. Doesn't he work for Novell now? He should have a powow with a marketing intern and receive some lessons on basic marketing.

    If they managed to do that, I might start to consider using it. It's a pretty amazing piece of technology, but don't let yourself be blinded to every other issue because of some neato tech toy fetish worship. As it is, I'm just appalled at how stupid they have been with this. They are just playing right into Microsoft's hands, sticking their head into the guillotine as Microsoft gives them some nice flowers to smell and pretty pictures to look at. Fucking so fucking pathetic.

    I've a c# developer, and I'd be tempted to play with mono, but I have to wonder why Python with the wxWindows and wxGTK toolkits isn't getting more exposure.

    My biggest problem with Java apps is that they look equally bad on any given platform. Based on what I've seen with wxWindows and wxGTK, the apps look like native apps. Is Python missing something essential?

      As someone who is a big fan of Python and uses it almost exclusively, I can say that the static typing of C# and Java has one big advantage. It's not better bug detection at compile time, or some nebulous concept of "enterprise readiness", it's intelligent IDEs with autocompletion etc.

      I prefer GvR's ideas [artima.com] about static typing for Python 3000 better (basically, all type checking is done via interfaces), but it doesn't actually exist yet :-).

    Mono may be a reimplementation of an MS product, even looking at the source, you'll notice a folder full of *nix implementations of windows API calls. But what does it really matter if it does the job you need it to?

    I started looking into it a few weeks ago when a project I was (am) working on required a scripting engine that could handle running scripts from anonymous sources, id est untrusted.

    We went through a large range of languages: python, perl, angelscript, php, lua, etc etc but ended up with a few rather large problems in all of them: either lack of sandboxing and protecting a system from the effects a script could have, or lack of documentation and user friendlyness for those who may not be too familier with programming (yes, we have to consider them)

    One of the dev's on the team brought up that .Net includes a set of security features that help to lock down scripts fairly tight, the problem being, our app has to be cross platform. This started us looking into Mono, which doesn't implement all the security features -yet-, but by our planned release date, they should be done, or very close.

    Another thing to consider, is that Mono will run any CIL compiled code, meaning that we can support a virtually innumerable count of languages, with very little excess implementation (find a compilier and link it into the project).

    So now we have: cross platform scripting (with sandboxing eventually), and the ability to present the users/programmers of the scripts with the syntax they are most comfortable with using.

    Not only that, but Mono is going to save us a fortune on our development costs, because we may be able to drop Qt GUI implementation from our project roadmap, which averaged about $6000 for each developer(Qt Enterprise with QSA), I believe, and had some -major- limitations on what you could use thier scripting language for (for example, you're not allowed to use it to expose features of Qt itself to the scripter, which may be neccisary for our project)

    Mono does the job, fits our specs almost perfectly, saves us money, and is built on CIL ECMA standards. What more -could- we ask?
    • "...when a project I was (am) working on required a scripting engine that could handle running scripts from anonymous sources, id est untrusted...

      My friend, you have some big balls. You're going to release something which needs a lot of security when the underlying security bits are unfinished and thus cannot be tested. Good luck with that.

    One of the things that hit me hard like a brick in the face is the disparity in the reaction of people claiming things under the name of the community.

    It's obvious to me from Miguel de Icaza and other Mono coders that what they're doing is as much for community as it is for their company. And yet this same community manages to react in opposite ways. Those who dislike a project (any project) will react from challenging the instigators with trying to prove their ideas work to downright maligning their efforts. On the other hand, people who like the project do their best to try and help out knowing it would benefit the community in the end.

    The odd thing is: it's the same project. The difference is in people. It's a tool that's not inherently evil. If people are divided in this case, it's by their own choosing.

    Whoever that blubbering guy is in LUGRadio that always has two reasons for anything, would you kindly reassess your intentions for making those comments as its clear from MdI's words what his are.
