The KDevelop IDE closes this gap and makes it a joy to work within a complete, integrated development environment, combining the use of the GNU standard development tools such as the g++ compiler and the gdb debugger with the advantages of a GUI-based environment that automates all standard actions and allows the developer to concentrate on the work of writing software instead of managing command-line tools. It also offers direct and quick access to source files and docu- mentation. KDevelop primarily aims to provide the best means to rapidly set up and write KDE software; it also supports extended features such as GUI designing and translation in con- junction with other tools available especially for KDE development. The KDevelop IDE itself is published under the GNU Public License (GPL), like KDE, and is therefore publicly avail- able at no cost—including its source code—and it may be used both for free and for commer- cial development.

  • Adding Support for Jamendo and Magnatune to Rhythmbox on Linux
    Walking in Light with Christ - Faith, Computing, Diary Articles & tips and tricks on GNU/Linux, FreeBSD, Windows, mobile phone articles, religious related texts http://www.pc-freak.net/blog Adding support for Jamendo and Magnatune to Rhythmbox on Linux Author : admin I'm using rhythmbox to play music on my Debian Linux. Rhythmbox is a good substitute for both audacious and xmms. XMMS is already very obsolete and it often crashes because of some of it's plugins. On the other hand audacious is sometimes having problems on my notebook working with it's alsa plugin or pulseaudio especially if I play something in youtube. With audacious my songs sometimes got stucked for some weird reason. With rhythmbox I have never experienced this kind of issues. Considering the fact that I'm a GNOME user rhythmbox is even more attractive for me. During about 2 years ago I've heard about the Jamendo - community of free, legal and unlimited music published under the Creative Commons licenses. Just about 10 months ago I've also discovered magnatune which is also a radio which allows free listening online of it's whole online catalogue. That's why it was really interesting for me to have this two nice music streaming services directly into my rhythmbox. I was very happy to discover that already a plugin that embeds the Jamendo and Magnatune Support to the Rhytmbox program. To enable Rhythmbox to support Magnatune and Jamendo type in your root terminal: debian:~# apt-get install gmpc-plugins gmpc-plugins-dbg debian:~# apt-get rhythmbox-plugins It's very likely that the rhythmbox-plugins might be already installed on your Linux, anyways I put the command above just in case if for some reason it's not installed.

The tips are fun and the hope of discov- ering hidden gems makes it a worthwhile task. John Southern Former editor of Linux Magazine I enjoyed Ubuntu Kung Fu and learned some new things. I would rec- ommend this book—nice tips and a lot of fun to be had. Carthik Sharma Creator of the Ubuntu Blog (http://ubuntu.wordpress.com) Wow! There are some great tips here! I have used Ubuntu since April 2005, starting with version 5.04. I found much in this book to inspire me and to teach me, and it answered lingering questions I didn’t know I had. The book is a good resource that I will gladly recommend to both newcomers and veteran users.

  • Part II, Window Managers and Desktop Environments
    Part II Window Managers and Desktop Environments The window manager is responsible for managing application windows and application- independent behavior, such as pop-up menus appearing in the background. The window manager manages the placement, borders, and decorations of all windows, and is responsible for the look and feel of your particular X session. Desktop environments typically include an integrated window manager, some sort of control panel, applications, and a consistent look and feel across applications. The chapters in Part II, Window Managers and Desktop Environments, are: Overview This chapter provides a conceptual introduction to window managers and desktop environments and briefly surveys some of the many window managers and desktop environments available for Linux. FVWM FVWM is a traditional window manager for Linux systems. It is now into its second major version, FVWM2. Window Maker Window Maker is an elegant X11 window manager designed to give integration support to GNUstep-based applications. It emulates the look and feel of OpenStep, the NeXTSTEP GUI. Enlightenment Enlightenment, often shortened to just E, may be the most elaborate and bizarre window manager available. Enlightenment’s motto, “time to rethink everything,” provides a good indication of the uniqueness and flashiness behind Enlightenment. Using GNOME GNOME, which stands for GNU Network Object Model Environment, is a freely available desktop environment that can be used with any of several window managers, including Enlightenment and Sawfish. Using KDE KDE, the K Desktop Environment, is another freely available desktop environment. KDE includes an assortment of games and utilities, as well as an integrated suite of office productivity applications..

  • Easy Slackware
    1 Создание легкой системы на базе Slackware I - Введение Slackware пользуется заслуженной популярностью как классический linux дистрибутив, и поговорка "кто знает Red Hat тот знает только Red Hat, кто знает Slackware тот знает linux" несмотря на явный снобизм поклонников "бога Патре­ га" все же имеет под собой основания. Одним из преимуществ Slackware является возможность простого создания на ее основе практически любой системы, в том числе быстрой и легкой десктопной, о чем далее и пойдет речь. Есть дис­ трибутивы, клоны Slackware, созданные именно с этой целью, типа Аbsolute, но все же лучше создавать систему под себя, с максимальным учетом именно своих потребностей, и Slackware пожалуй как никакой другой дистрибутив подходит именно для этой цели. Легкость и быстрота системы определяется выбором WM (DM) , набором программ и оптимизацией программ и системы в целом. Первое исключает KDE, Gnome, даже новые версии XFCЕ, остается разве что LXDE, но набор программ в нем совершенно не устраивает. Оптимизация наиболее часто используемых про­ грамм и нескольких базовых системных пакетов осуществляется их сборкой из сорцов компилятором, оптимизированным именно под Ваш комп, причем каж­ дая программа конфигурируется исходя из Ваших потребностей к ее возможно­ стям. Оптимизация системы в целом осуществляется ее настройкой согласно спе­ цифическим требованиям к десктопу. Такой подход был выбран по банальной причине, возиться с gentoo нет ни­ какого желания, комп все таки создан для того чтобы им пользоваться, а не для компиляции программ, в тоже время у каждого есть минимальный набор из не­ большого количества наиболее часто используемых программ, на которые стоит потратить некоторое, не такое уж большое, время, чтобы довести их до ума. Кро­ ме того, такой подход позволяет иметь самые свежие версии наиболее часто ис­ пользуемых программ.

  • Experience with a Livecd in an Education Process
    EXPERIENCE WITH A LIVECD IN AN EDUCATION PROCESS Experience with a LiveCD in an education process Jan R˚uˇziˇcka, FrantiˇsekKl´ımek Institute of Geoinformatics Faculty of Mining and Geology, VSB-TUO E-mail: [email protected] Key words: LiveCD, GIS´akLiveCD, Distance Learning, E-learning Abstract The paper describes how can be LiveCD (Bootable CD) used for geoinformatics distance learn- ing. We have prepared one LiveCD with basic software for learning geoinformatics and we have some feedback from users and teachers. The paper should evaluate this feedback. LiveCD is a CD-ROM, that can be used as a bootable device. After booting from the CD, the user can access all resources compiled to the CD. There are operating system (usually based on GNU/Linux) and (user, desktop) software installed and configured to be used directly after boot. Our CD named GIS´akLiveCD contains basic GIS software such as UMN MapServer, GRASS, Quantum GIS, Thuban, JUMP, GPS Drive, Blender and we work on other soft- ware packages such as MapLab for UMN MapServer, PostGIS, GeoNetwork Open Source, CatMDEdit, gvSIG, uDIG. GIS´akLiveCD contains set of spatial data from the Czech Re- public. Main part of the CD are tutorials for GIS software. CD is open for other e-learning materials. Now we have about 20 students using our LiveCD and few other users that are not curently our students. The paper should show Pros & Cons of the LiveCD usage for a distance learning. LiveCD Live CD is bootable CD-ROM with operating system and installed and configured programs. It is ready to use as full installed system directly after boot from CD-ROM drive.
