If you can't fix it, rebrand it
The reputation of the KDE ecosystem was tarnished by a crappy release process for KDE4. Essential desktop components simply weren't ready for release in 4.0 and 4.1 (some of them still are mostly vaporware) after a huge barrage of hype had massively raised expectations, and this generated a lot of (well deserved) bad publicity. The answer?
Go and rebrand it, so that the development process can be broken up more easily and people will be persuaded to blame the right developers for each component. And while we are at it, let's throw out KDE's well-earned reputation for deep integration, the idea of the DE as a complete platform for users and developers. Let's give users the idea that KDE is just a "compilation" of bits and bobs thrown together for no particular reason, on the way overlapping as much as possible with the concept of "distribution", making it fun for companies to explain the difference and for developers to understand what they can and cannot rely on for their apps. Now KDE is supposed to be just a "community", a "club" of like-minded (C++) people hanging out in Gran Canaria and the like.
Yeah, that will be fun.
Honestly, I've been a big KDE fan for ages, but the development process for KDE4 was clearly wrong on so many levels. Developers' reactions to user feedback in the last two years have been astonishingly patronizing, and this is just another instance of it. Just admit that errors were made and get to work, please, instead of wasting time jet-setting from one "conference" to another (preferably in remote islands with good nightclubs), talking about marketing b*llocks.

Akonadi vs Plasma: a tale of disorganized, randomic development
The Akonadi::ItemView class, which should provide a default, out-of-the-box view of data stored by Akonadi (KDE 4 technology), depending on the type of resource it represents, cannot be included in a Plasma.Applet (KDE 4 technology) but only in a KXmlGuiClient or KXmlGuiWindow (KDE 3 technology).
Clearly dogfood isn't as tasty as apple pie.

Amarok 2 revisited
Considering the sort of negative person I am (I'm sure scientologists would classify me as "suppressive personality" in zero time), it doesn't come as a surprise that one of the most popular items on this blog is a rant about Amarok 2. Having recently upgraded my Linux laptop, however, I found that Amarok was also upgraded to release 2.2.1, and I decided to give it a go. The experience was, overall, a positive one, so I thought I owed to the developers a follow-up to my previous rap.
Amarok 2.2.1 finally addresses 99% of the problems and regressions that plagued 2.0. The terrible default layout is now highly customizable (click on View -> Lock Layout to unlock the widgets, then drag&drop them where you want), so you can recreate the much-saner 1.x disposition. You can also customize the top toolbar (which by default is wasting so much screen real-estate, you could probably display three different applications in the same amount of space) to be more compact, by selecting View -> Slim Toolbar. Support for radio and podcasting is now first-rate (I don't know about external disks/mediaplayers), and plugins for various Internet services are quite good. MySQL is back to being an optional back-end for the internal music catalog. In short, if you still are on 1.x and can upgrade to KDE4/Qt4, you should probably give it a go.
So, 18 months down the line, Amarok is basically back to where it was in release 1.4, plus some eyecandy and (we are told) a better, more modular infrastructure. In order to achieve this, developers endured a year of bad publicity and hate-mail from their own users, lost market share, and basically looked hapless at prioritizing features and designing interfaces.
Was it worth it? To me, it still looks like another proof that benefits of "big rewrites" are dubious at best, like Joel Spolsky said so many years ago. I suspect we will eventually come to say the same about the whole KDE4 process, but I guess the jury is still out on that one.

Kubuntu Karmic Koala and Radeon 9600 Mobility M10 (RV350) xorg.conf magic
The upgrade to Kubuntu 9.10 "Karmic Koala" threw me back to the glorious 90s, when installing Linux would invariably require long battles with the infamous XFree config files. Hours and hours wasted trying out magic incantations in order to escape the brutal world of command-line interfaces. !FUN
Anyway, here's a bit background: basically, ATI stopped releasing proprietary Linux drivers for their old cards. So you can either use the old drivers, or move to the open-source ones (a complete rewrite, which only recently got good enough for real use). But here's the problem: the version of (KDE window manager) KWin shipped with Karmic crashes horribly with the old ATI drivers, and recent Xorg releases don't really work well with them anyway. So you haven't much of a choice: move to the free drivers and thank Stallman for inventing the cure to the annoying problem of manufacturers dropping support for products after less than five years.
The problem with the open-source drivers, however, is that running with default parameters will give you shockingly bad perfomance, especially for 2D (weird). I was forced to delve into xorg.conf and turn on all the "turbo-boost" switches I could find. At the moment, I'm getting decent result with the following parameters:
Section "Device" Identifier "Configured Video Device" Driver "radeon" Option "AccelDFS" "on" Option "AccelMethod" "XAA" Option "MigrationHeuristic" "smart" # "greedy" works well also Option "EnablePageFlip" "on" Option "EnableDepthMoves" "on" Option "ColorTiling" "on" Option "FBTexPercent" "0" Option "AGPMode" "4" # this is the real kicker Option "TripleBuffer" "true" EndSection
Note AccelMethod being set to XAA. In the future that will probably be EXA (which apparently is a newer algorithm), but my experiments with it included too many crashes for my taste.
There are a few other parameters that I scavenged from Google and man radeon, but they mostly resulted in crashes on my machine (tbh, I'm not sure they were always the guilty party, but better safe than sorry):
- "AGPSize" "128" -- from what I understand, this should just be the amount of video RAM you have.
- "EXAOptimizeMigration" "on" -- relevant only if you use EXA
- "XAANoOffscreenPixmaps" "on" -- no idea what this is, but my card doesn't like it
- "BIOSHotkeys" "on" -- my screen-related Fn-* hotkeys work anyway, even without this parameter
- "AGPFastWrite" "on" -- this hangs X on my laptop (Rock Pegasus Ti)
I put this here so I may remember to search my blog next time instead of wasting time going through random forum threads, but I hope it may be of help to fellow Radeon linuxers. All in all, KDE 4.3 is lovely, but it kinda reminded me that five years is quite a long lifespan for a laptop.

Kubuntu 9.10 / KDE 4.3.3 first impressions
- Upgrade installer choked on finding out that python2.6 was already installed. Had to fall back on hardcore dpkg commands to fix it. I understand most "upgraders" had similar issues. -1
- Keeps complaining that it can't find my uid-identified partitions straight away (slow HAL?). Considering it eventually manages to mount them just fine (and that the uid scheme was forced upon me by a previous Kubuntu), it just seems stupid. Any idea how I could stop the nagging? Meanwhile, -1
- Sluggish. Maybe because KWin would crash on ATI drivers and I had to switch back to the free ones. -5
- Eyecandy is fabulous, and very consistent. Much better than Vista.+1
- Managed to recreate my old desktop setup almost flawlessly. Most 4.0 regressions due to Plasma have finally been addressed. +1
- Many (most?) widgets are useless. Only few of them "get" what Plasma is about. I guess this will be fixed in time. +0
- The Widget Dashboard, once you "get it", is fantastic. Makes things like Quick Launcher absolutely redundant. +1
- Configuration utilities have been somewhat cleaned up, in a long-overdue effort. +1, but for the love of God stop with the Gnome-like zealotry.
- Looks like KNetworkManager won't properly manage my wifi. Somewhat balanced by forcing people (me) to rediscover the joys of full-speed cabled access. Still, -1 (and I'm being generous)
- KPackageKit finally gives us a Qt-based alternative to Synaptic. +1
- the gmail-plasmoid. Never found a decent counterpart for 3.5. +1
- UI to Power Management features is finally as good as anything in the Windows world. Maybe better. +1
- Shortcuts every-flipping-where. One day, I might even use them. +1
- Lots of good repositories for fresh software, without having to jump through hoops. And the ppa/apt-add-repository combo is a winner. +1
Total: +1. So I guess it was all worth.
