K Desktop Environment - Educational applications and Games

Learn and Discover with the KDE Educational applications Desktop Planetarium, KStars, provides an accurate graphical simulation of the night sky, from any location on Earth, at any date and time. It can control telescopes and has many tools for the amateur or professional astronomer. This new version now shows millions of stars, can predict conjunctions and has a Sky Calendar. If you start it for the first time, a welcome wizard will show. After choosing your location, you can click the "Download Extra Data..." to select additional star and image data to install. Millions of stars are available in the packages, as well as inline thumbnail images which show images of objects right on the sky. There are several interesting educational applications of this program as well. Pushing "CTRL-F" will bring up the find dialog. Type a name of a heavenly object to find it, like the moon. You might want to turn off "Toggle opaque ground" (most right button on the toolbar) to see the object if it is below the horizon. If you now choose "Equatorial coordinates" by hitting the space bar and set the time per second in the toolbar to 1 hour, watch. The moon moves - but, seen from the equitorial, not in a horizontal line! Why is that? The reason is that the earth spins, but not entirely as you might expect: there is a tilt and a wobble to the spin of the earth, and thus the observer moves up and down... Making science visible to children in such a way is a strong tool in the classroom, and this is a truly educational application. And it is not just for children, so be sure to have a look at this application if you are interested in astronomy!

K Desktop Environment - Extended Development Platform

Educational Applications and Games Overview The KDE development platform contains common UI widgets, but also libraries for interaction with hardware, multimedia, configuration and network transparency, among others. Some changes affect most or all the KDE applications. The most notable of these improvements include: The 'file open' and 'file save' dialogs have been touched up. Using the same infrastructure as Dolphin, they now also include a zoom slider and can show file previews. Sharing such user interface elements ensures a smooth and consistent user experience.

K Desktop Environment - Applications Leap Forward

The file manager, Dolphin, has seen several changes that affect your work flow and make file management more efficient. Folders and tabs can open automatically when you drag a file over them, making it easier to organize your files. You can also navigate with the Breadcrumb bar. And if you want, you can have that Breadcrumb bar always display the full path. To configure this, go to the "Dolphin Preferences" in the Settings menu and put a tick in front of the "Show full path inside location bar". You can enter a custom location in the Breadcrumb bar by clicking on the right of it, and selecting "edit". Revert it to its former state by clicking the yellow icon on the far right. Like with all text input fields in KDE, you can select a line of text and middle click in the field to add the selected text at that position. If you middle-click-paste text onto the "Clear text" icon (left facing black arrow) on the right, the current location will be replaced.
