Hackers on Linux's Exciting Desktop Future
Gentu writes "OSNews features two interviews with prominent open source developers: Robert Love started working at Ximian this week and he will be leading the 'effort to improve the Linux desktop experience via kernel development'. In this Q&A, he explains what he will be working on hardware integration, freedesktop.org's D-BUS & HAL, low latency optimizations, power management, X & 3D and a 'Linux answer to WinFS'. The second interview is with Red Hat's Owen Taylor. Owen speaks of GTK+ development and where he sees the project going in the Gnome 3 timeframe: freedesktop.org's new X server, Cairo support, GTK#, OpenGL & other widgets and more."
When I first used Linux and I ran X, my thought was "damn, this is slow." This feeling is echoed by a lot of other people. It's nice to see that a replacement is on the way. Hopefully, in addition to reducing latency, an effort will be made to improve some other areas in X. Copy&paste is still inconsistent in X and just annoying. Nonetheless, fixing the problems with X is a BIG step toward Linux being viewed as acceptable on the desktop. That is the one thing that particularly caught my eye.
Help me. I've been modbombed by a few people with entirely too much time on their hands.
When someone announces they will be working on a project -- low latency optimization, for example -- you can pretty well tell that they are *actually* working on it because the code is released and you can look at it. It might have mistakes, crash a lot, or be missing features, but another developer can build on it if the original coder leaves the project because of other commitments or just out of boredom.
On the other hand, with proprietary code you are never quite sure where you stand. The company holding the source can claim they are spending the next month concentrating their resources on security issues, and if the program appears to be as insecure and bug-ridden as before you aren't sure if the developers took a month-long cruise to the Bahamas and blew it off or if they are actually inept at security. If you depend on that program for your own product, you can't even fix the problems you encounter if the developer decides to ignore or even kill the product because the source code is secret. And for those that have a paranoid bent, it's entirely possible for certain companies to sow FUD by claiming to be working on some incredibly desirable improvement they have no intention of delivering, or to leave hidden programming hooks which allow only certain products to use it.
Too bad our founding fathers could not have forseen the entire source code/copyright issue. I would like to think they would have required complete specificity with regards to programs -- if you wanted to copyright a program, you would have to show exactly how it was created using industry-standard tools. It would not only prevent monopolistic power in one programming area (*cough* operating systems *cough*) from extending to another, but it would be one heck of a lot easier to prove copyright *infringement* because the source code from various products could be compared.
Plus, if the filesystem is truly a relational db, then it can emulate and distro's directory tree for legacy applications that need it.

I'm an advocate for Linux in many situations. I've bugged everyone to hell since about 1997 to use it in server applications (not much of a BSD guy). I think it works great in masquerading situations. For quite some time I've felt that no Windows machine should be allowed directly onto the Internet, and that a non-Windows machine should masquerade traffic onto the net. I also think Linux is a far superior development environment to any other. That said, I still use a Windows desktop.. why?
For me the Linux desktop (or X with KDE or GNOME, as we're talking here) lacks a dock application. It also can't run everything I want without any hassles.. whereas I can just use VMWare/Virtual PC on Windows. Running Simcity 4 in VMWare under Linux, however, is not a great option
As a developer, the Linux desktop also seems pretty scary. You've got KDE and you've got GNOME.. and the applications from the system you're not using can end up looking like ass. Of course, it's a lot better than developing for Windows, but we need more integration, and I'm glad OpenDesktop is trying to do this, and that GNOME and KDE are trying to work together.
Also, I find Redhat 9 to be deadly slow on the desktop. SuSE 8 has proven to be much better (a KDE vs GNOME here?).. but I'm waiting for Fedora Core 2 (with the 2.6.0 kernel) until I make my next foray into trying Linux as a desktop OS. (I continue to use SuSE 8 via emulation for development purposes)
But make no bones about it. Linux is using the right methods. Windows is not. Linux might still be behind Windows and OS X in many areas, but they have a far better foundation, and I'm confident the Linux desktop will prevail. And.. I can't wait.

In the light of this, the recent explosion of corporate interest in Linux on the desktop has been a huge boon. They have the resources and the need to integrate various components. There's no way freedesktop.org could have happened in the old scenario. The amount of integration work that has happened/is happening in the last couple of years is stunning. I lurk on both gnomedesktop.org and dot.kde.org, and the attitude of the developers towards integration has changed significantly.
I'll stick my neck out and predict that with the new audio infrastructure materializing by middle of next year, LotD is going to be so kick-ass by end of 2004 that the only MS can stop us is if they manage to make linux illegal.
It's not transparent windows per se that we are looking for. It's the ability to have completely smooth, shaped edges and better anti-aliased text. It's also amazing what a little candy like a real drop shadow does to the UI. It helps your eye see the edges of ui elements better. On OS X, for example, many windows have no frame around them at all. But they still look like a window because of the light shadow that is drawn underneath it. This allows two completely white rectangles to be stacked on top of eachother and still look like separate windows.
True transparency will also help in drawing icons without resorting to the current nasty hack of having to grab the background pixmap and then blend the png into it.
Essentially translucency (true alpha-channel support) in the x server is a great boon to us all, especially those into art and drawing, but also just those of us that want a desktop with no more jaggies.
Finally, this support for alpha channel and window compositing actually makes the gui appear much faster, because redraws are virtually eliminated. If you want to go back to the old Windows 3.1 (or even GEM) interface of low-color, jagged edges, go ahead. I'll save my eyes.
