Compiz Project Releases C++ Based v0.9.0

werfu writes "Compiz 0.9.0, the first release of Compiz rewritten in C++, has been announced on the Compiz mailing list. See the announcement for more info." Compiz has for years been one of my favorite ways to make Windows users envious, despite my (Linux) systems' otherwise low-end graphics capabilities. Besides the switch to C++ from C, this release "brings a whole new developer API, splits rendering into plugins, switches the buildsystem from automake to cmake and brings minor functionality improvements."

  2. Summary Fail by drinkypoo · · Score: 5, Interesting

    The relevant words from the announcement are "complete rewrite". Or in simpler terms for the users, you do not want to run this until it reaches 0.10 (also as per the article.) This is a development and not stable release. (Sure would be nice if they would go 1.0 instead of .10 if it's going to be a stable release...)

    Here's the stuff from the announcement interesting to users:

    Rendering framework split into the composite and opengl plugins, the former
        making compiz a compositing window manager and the latter performing that
        compositing using OpenGL. Such a split will allow new rendering plugins such
        as XRender and Clutter to be developed as well as for compiz to run as a
        non-compositing window manager

    Added support to drag windows to edges and have them fill the adjacent side of
        the screen

    * Added support for automatic wallpaper rotation
    * Added edge support to grid plugin so windows can easily be resized by dragging
        to an edge or corner

    Everything else is of interest only to developers...

      So in other words, you find at least one aspect of it to be very useful. While some window effects are just pure eye-candy (e.g., wobbly windows), many of the added desktop effects provide various degrees of enhanced functionality. This includes:

      • Desktop presentation, be it cube, zooming, or task switching, can be molded and animated to allow the user to better understand and utilize the multiple desktops.
      • Transparency allows information to be literally overlayed, decreasing the intrusiveness of upper-stratum menus and windows.
      • Various effects can tag and categorize different applications or application states (active, inactive, shaded, etc.)
      • The added capabilities allow enhanced usability tools, like magnifiers and mouse location, to be well-integrated and seamless.

      Don't dismiss the suite as just eye-candy; if the main perception of Compiz is that it exists only to make things more fun and prettier, then its overall value to the desktop is understated.

    I understand, but for speed I expect that C++ still outperforms Java, and while C should outperform both of them, C doesn't feature encapsulation, polymorphism and all the other goodies that OOP provides.

    No, C is exactly as fast as C++. C++ only becomes slower if you use certain features that have a performance impact. Example: if you use exceptions, there is a performance penalty. If you don't, you don't get the performance penalty. That is one of the design principles of C++: nothing can be included into the language that slows down code that does not use/need it. The main slow downs you will see in your average C++ program, over the corresponding C, is the use of the string class as opposed to the nasty but fast strcpy and friends, and the extra indirect function calls due to virtual functions (which causes a branch misprediction and hence a pipeline flush on modern cpus, costing you a bunch of clock cycles). Still, you only pay for virtual if you choose to use it, and manually implemented virtual function calls are used all over the place in good old C, with the same effect. Furthermore, C++ templates allow code re-use with exactly 0 performance loss and while the error messages are ugly, they're still a whole load prettier than doing the same thing the C way with recursive includes and lots of preprocessor madness. And you can link to existing C code/libraries without any problems. Frankly, there is no valid reason for starting a new program in C in this day and age.

    Fewer Viruses - While this is technically true, most viruses I've seen installed on users machines are the result of users actively clicking and running an executable on their machine. While not running in root mode by default on Linux helps to prevent some of the damage, I think a virus running as a regular unprivileged user could still cause a lot of damage. This is also ignoring the fact that if the same incompetent users if presented with a message asking them to perform administrator actions for no reason at all would still click on "Yes", even if there should be no reason for them to do so, as long it promises smiley icons.

    Lower cost of Ownership - Last time I went shoppping for a computer, I didn't see any discounts for not having Windows installed from the get go. Either you go with Dell/HP/Lenovo, and they only offer windows, or when the offer Linux, it's the same price, or only a little cheaper, but you get a lot less selection of machines you can get. The other option is to build your own machine from off the shelf components. This is my favourite option, as you can get exactly what you want, but you will end up spending more.

    CLI/Scripting system - Almost nobody except tech geeks cares about this. Also, Powershell on Windows isn't all that bad. It has its pluses and its minuses.

    Most open source software runs on it - Most all of open source that is worth running will run on Windows. Maybe not all of it, but most of the more important stuff. Conversely, almost no closed source software runs on Linux. Which might not matter to you, but if you're trying to get work done, having things like Photoshop, Outlook (hate it but necessary for business), and many other closed source programs, makes a big difference.

    Drivers - Sure you get drivers for all the old stuff. But are you sure that shiny new piece of hardware that just came out last week will run to its full potential. Probably not. And there's also plenty of older hardware that I had that I couldn't run on Linux.

    No Blue Screen - I haven't seen a blue screen on a Windows machine in many years. And when I do, it's usually because of bad RAM, causing something to get corrupted. Blue screens still exist, but they don't happen quite as often as they used to. I imagine most Linux systems would also crash pretty badly when they have bad memory.

    I'm not some Windows Zealot. I use Windows when it makes sense, and I use Linux where it makes sense. But I don't really think that that any of the reasons you mentioned are valid. Especially if you're talking about home desktop use. Which in the case of Compiz, is exactly the kind of people we are talking about.

    On Windows, too much time is spent hacking up the registry to make crap work or work right. Just this last Thursday, I had to manually scan the registry to delete every reference to a printer driver that kept killing someone's spooler service... because the spooler service needed to be running to delete the printer normally. If it had been a unix system, I could have just edited a line in a file and been done.

    I still have Win98se running on an old machine for old games. Win98se is actually snappier than modern Linux, which is in turn snappier than WinXP/7. How much window compositing did Win98se do? Firewalling? Multi-user? Even the 1998 version of Linux had multi-user support and ipchains.
