GNOME Shell No Longer Requires GPU Acceleration
An anonymous reader writes "The GNOME 3.0 Shell with the Mutter window manager no longer requires GPU acceleration to work, while still retaining the compositing window manager and OpenGL support. GNOME Shell can now work entirely on the CPU using the LLVM compiler via the Gallium3D LLVMpipe driver. This will be another change to Fedora 17 to no longer depend upon the GNOME3 fall-back, which is expected to eventually be deprecated and further anger GNOME2 fans."
GNOME is a perfect study in how not to architect a software system. Everything about it is wrong.
The first mistake they made was trying to cobble half-assed object-oriented support onto C, rather than just using C++ or Objective-C. Everything about GObject is stupid and counterproductive. It makes writing code a real pain in the ass, since you need to use typecasting macros all over the place. Worse, this sort of code promotes library design that's slow and inefficient. To make it even worse, this style of C code is so convoluted that it is not optimized well by compilers, resulting in binaries that are far slower than they should be.
It basically goes totally downhill after that. This bullshit with GPU acceleration being required in the first place, and then this additional bullshit involving LLVM, is yet another in a long list of flaws and horrible decisions.
I encourage all of the developers that I mentor to use GNOME and to get a good look at its internals. I just make sure that they know not to do what GNOME has done. By seeing the mistakes firsthand, it's less likely that they'll repeat them in the future with the software that they create.
Mod AC up hes his spot on...

You're using one adjective (slow) with a bunch of different adverbs (all those words that end in -ly), fyi.
