As I sit here right now, I notice that my Arch Linux package manager ("pacman") is downloading KDE 4.6.1. KDE 4.6.0 was released at the end of January, and it was automatically installed on my system shortly after it was released. I don't notice a lot of new features, but there is one feature that I now use all the time. For a long time, dragging a KDE window to one of three edges of the screen would cause it to either be maximized (top) or resized to fill either the left half (left) or right half (right) of the screen for easy side-by-side tiling. This feature exists in Windows Vista, and I know a certain fiancée who uses it all the time. In KDE 4.6.0, they've added more granularity – the left and right edges of the screen are now partitioned into thirds. Dragging a window to the top or bottom third causes it be resized for a quarter of the screen as opposed to a half of the screen. The middle third resizes for half of the screen as before. So now it is easy to do even more sophisticated tiling by dragging, and I use it all the time.
But I can't use that feature on my machine at the office (Fedora 14) nor the HTPC connected to my TV (Ubuntu 10.10). That's because both Fedora and Ubuntu are on 6 month release cycles, and KDE is also on a 6 month release cycle. Consequently, my Fedora office machine is stuck back on some KDE 4.5.5 components, some 4.4.10 components, and some KDE 3.5.10 components, and it seems arbitrary which components are which KDE version. More importantly, it may be another year before I can ever expect to get quarter-window tiling on these machines (enterprise distributions, like RedHat EL, are even worse; you may wait a decade for features to trickle down the official release path). There are ways in which these distribution gatekeepers try to get around this delay by supporting auxiliary repositories of updated software, but then that is a whole other mess I would have to cover in another rant.
It's frustrating to me that these Linux "distributions" take on a release cycle that elevates them to a level on par with the software that supposedly is the sole driver of their value. It is one thing to wait for the next release of Windows to come out because Windows is a product itself; however, Ubuntu or Fedora is just a distribution – a glorified collection of independent software components that are possibly rapidly evolving and have some dependency structure on each other. Arch Linux recognizes this. It recognizes that a good package manager trumps a great "distribution" any time, and pacman is a great package manager (and it doesn't have a stupid name, like "yum" or "apt-verb", and isn't just a wrapper for yet another silly-named package manager (like "rpm" or "dpkg")). In doing so, it allows for everything from minimal Linux installations to maximally bloated Linux distributions, with the distinction that every package is truly up to date (and not just up to date relative to some arbitrary collection of version numbers). Arch Linux is not the only distribution with this nice feature. Gentoo, for example, also uses a rolling release cycle... and Gentoo is also well-known for its excellent package manager "emerge".
[ ...and on the subject of package managers, the pacman-wrapper yaourt augments the terrific pacman with the ability to automate building packages from source, even when you want to both customize your build environment and automatically build updates when they are available... so yaourt brings some of the nice features of Gentoo's rolling release cycle directly to Arch Linux's rolling release cycle ]
Frustration is certainly not the only feeling I can associate with the Fedora and Ubuntu distributions forced on me (by my employer in the former case and Boxee in the latter case); there's also fear. Every six months with Fedora or Ubuntu, you have to go through the horror of upgrading the entire distribution at once. I'd rather tackle upgrading problems with one package at a time as opposed to the entire OS twice a year. Not to mention the psychological trauma that upgrades cause – regardless of how nice the system works, I always have in the back of my head that maybe it would be better if I just formatted and installed fresh right now (but then the fear of the next upgrade prevents me from doing that). An operating system should not be a major cause of distress, but I find nothing but distress in Ubuntu, Fedora, and the other deleterious distributions in that pernicious pack that do not adopt rolling releases.
So there you go. I just quarter-window tiled this window, and it saddens me that when I go back into the office on Monday, I will lose half my day to half-window tiling and resizing... and then I'll lose a day or two later this year when FC15 comes out. Stupid six-month distribution release cycles...
