KDE 4.3 was released just yesterday, and it comes with a lot of great new features and improvements, like the the new Plasma theme called Air, new Plasma widgets, several improvements to Dolphin, the default KDE4 file manager, improvements to the KDE games, and these are just a tiny part of all the improvements KDE4 introduced. The full announcement including reader's changelog can be found on the official KDE4 website, here.

digiKam is a free photo management application for KDE, and probably the best alternative to Picasa from Google. digiKam includes many photo retouching and photo manipulation functions, and it allows to organise your collection into albums. Kubuntu 9.04 comes with version 0.10 for KDE4, but in the first beta of version 1.0 was released on June 9. Here are several easy steps for compiling digiKam from source and installing it on a Ubuntu/Kubuntu Jaunty machine.

With the release of KDE 4.2, Google Gadgets became fully integrated into Plasma. You can add them to your desktop with a few clicks of your mouse, unless you happen to be a Kubuntu user. For reasons that are outside the scope of this article, Kubuntu developers decided to remove the Google Gadget code from Plasma. Being the stubborn hackers that we are, however, we are going to get them back. This will require a little compiling of software, but I will walk you through each step.

Inspired by QuickSilver for Mac OS X, Katapult is an application launcher for KDE designed to allow faster access to applications, bookmarks, and other items. It is plugin-based, so it can launch anything that is has a plugin for. Its display is driven by plugins as well, so its appearance is completely customizable. It was inspired by Quicksilver for OS X.

But, there's always that one program that uses the KDE QT library to provide a front-end. For example, I love to listen to music, and nothing beats AmaroK for me. But, every time I use it, the color scheme and icon theme completely clash with my Gnome desktop.

KDE 4.1 can also be sluggish, slow, sticky and whatnot - although it is running on a power machine. The reason behind that is most likely the graphics hardware: a NVIDIA card. Unfortunately, atm it doesn’t look like that NVIDIA will fix the drivers anytime soon. But there are hints and workarounds available to the ones who are willing to fiddle with the details.

It would be nice to have a local DNS cache to reduce the number of DNS requests. h2. pdnsd to the rescue h3. Installation p. *pdnsd* is a local DNS cache that reduces _external_ DNS requests to a minimum. You can find it in the repository of your distribution. The installation is pretty simple: <pre> <code> # Ubuntu/Debian: sudo apt-get install pdnsd # Gentoo: emerge pdnsd </code> </pre> h3. Configuration p. Depending on your distribution, the configuration file is located in different directories. Let's open it in our editor of choice: <pre> <code> # Ubuntu/Debian: gksudo gedit /etc/pdnsd.conf # Gentoo: nano -w /etc/pdnsd/pdnsd.conf </code> </pre> p. Here is my pdnsd.conf.

Starting pdnsd <pre> <code> /etc/init.d/pdnsd start </code> </pre> p. pdnsd should now listen to port 53: <pre> <code> hydra linux # netstat -ln Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 ::ffff:127.0.0.1:53 :::* LISTEN udp 0 0 ::ffff:127.0.0.1:53 :::* </code> </pre> p.

The answer is not always as straightforward as one would hope, and sometimes quite scattered across several sources. This guide attempts to complete guide to how to manage sessions and autostart applications in KDE, as well as to provide a central reference for links related to the topic.
