C++ language tutorial is a quick tip type tutorial (try saying that five-times-fast.) It provided some useful information to me concerning namespaces in C++.
On the KDE front a HUGE amount of activity is going on in preparation for the move to Qt 4.0. Because of the underlying structural changes that will take place, many developers are taking this opportunity to re-evaluate and extend KDE. Some of the more interesting projects are Lyceum, a KDE documentation project centered around tutorials organized the way college classes are. Tenor a Contextual Link Engine. The best way to understand it is to read the article. Its pretty amazing stuff and absolutely blows away ANYTHING currently available in terms of desktop search functionality. You can read more on Tenor here. This kind of innovation really shows off the power, flexibility, and integration that is available to KDE. No desktop anywhere comes can compete with KDE on the technical level! KDE is also moving from CVS for version control to Subversion which will allow for better control of existing code along with more flexible control of our projects. There is even talk of porting KDE to Windows. Lots and lots of code theory with lots and lots of work to do. The future for KDE is looking very bright indeed.
