About Enlightenment We are dedicated to providing advanced graphical libraries, tools, and environments. Currently, the project is made up of three different components: Enlightenment DR16, Enlightenment DR17, and the Enlightenment Foundation Libraries. While we are best known for the Enlightenment Window Manager itself there is a long history of providing advanced libraries and tools to support the window manager and other applications, such as Imlib, Imlib2, and FNLib which extend far beyond the window manager itself in scope. Today, in development toward the DR17 Desktop Shell we have created an entirely new set of libraries and tools that provide more power and flexibility than any other group of graphical libraries available, The Enlightenment Foundation Libraries.

Xfce Features Xfce provides a lightweight desktop environment with a desktop manager drawing a wallpaper and allowing you to have icons on your desktop, a panel with numerous plugins, a standard compliant window manager with a compositing manager, a settings manager to customize your desktop environment, a modern and easy to use file manager and a session manager which allows you to save the current session, autostart applications, shutdown, reboot, suspend or hibernate your computer. Xfce also provides common applications, designed for the best user experience. Among those applications are: a text editor, a sound mixer which supports multiple sound cards, an application finder to launch your applications in an easy way, an image viewer, a modern terminal emulator, an iCal based calendar to manage events and appointments and a CD and DVD burning application.

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!

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.

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.

The Direct Rendering Infrastructure, also known as the DRI, is a framework for allowing direct access to graphics hardware under the X Window System in a safe and efficient manner. It includes changes to the X server, to several client libraries, and to the kernel (DRM, Direct Rendering Manager). The most important use for the DRI is to create fast OpenGL implementations. The DRI is an integral part of X.org 7.x, and integrates with Mesa, an open source implementation of the OpenGL API. Several 3D accelerated drivers have been written to the DRI specification, including drivers for chipsets produced by ATI, Matrox, 3DFX, and Intel. The DRI was initially developed by Precision Insight, Inc. (PI) in cooperation with, and partially funded by Red Hat Inc., and SGI. Since PI's merger with VA Linux, and VA Linux' subsequent exit from Linux, the DRI is being maintained by Tungsten Graphics Inc., a new company formed by some of the initial DRI developers from PI. Tungsten Graphics is the current focal point for DRI development, and many open source developers continue to contribute to the project through the DRI project.

Durante o FLISOL, divulgado aqui no blog, pessoas de várias áreas procuraram conhecer mais sobre o Linux. Entre estas pessoas estavam professores procurando algo mais para passar para crianças de escolas públicas. Na ocasião comentamos e mostramos alguns softwares da distribuição edubuntu, mas eu ainda achava que era pouco. Ontem tomei conhecimendo do projeto Academia. O Academia é um liveCD, criado por Armando Silva, baseado no Knoppix com componentes do Knotix e Sidux com vários aplicativos educacionais como Gcompriz, Childsplay, TuxMath, TuxType e alguns aplicativos do KDE-Edu. Você pode fazer o download do Academia aqui. O md5sum é 2b44716a5d957781d1003be20b764a06. Eu estou baixando e logo estarei fazendo mais comentários sobre seu conteúdo. Por enquanto devo parabenizar o Armando pela bela iniciativa. 1. 1 On January 1st, 1999, André
