The GNOME Desktop Environment
The GNOME desktop environment Miguel de Icaza ([email protected]) Instituto de Ciencias Nucleares, UNAM Elliot Lee ([email protected]) Federico Mena ([email protected]) Instituto de Ciencias Nucleares, UNAM Tom Tromey ([email protected]) April 27, 1998 Abstract We present an overview of the free GNU Network Object Model Environment (GNOME). GNOME is a suite of X11 GUI applications that provides joy to users and hackers alike. It has been designed for extensibility and automation by using CORBA and scripting languages throughout the code. GNOME is licensed under the terms of the GNU GPL and the GNU LGPL and has been developed on the Internet by a loosely-coupled team of programmers. 1 Motivation Free operating systems1 are excellent at providing server-class services, and so are often the ideal choice for a server machine. However, the lack of a consistent user interface and of consumer-targeted applications has prevented free operating systems from reaching the vast majority of users — the desktop users. As such, the benefits of free software have only been enjoyed by the technically savvy computer user community. Most users are still locked into proprietary solutions for their desktop environments. By using GNOME, free operating systems will have a complete, user-friendly desktop which will provide users with powerful and easy-to-use graphical applications. Many people have suggested that the cause for the lack of free user-oriented appli- cations is that these do not provide enough excitement to hackers, as opposed to system- level programming. Since most of the GNOME code had to be written by hackers, we kept them happy: the magic recipe here is to design GNOME around an adrenaline response by trying to use exciting models and ideas in the applications. -

freiesMagazin Juni 2016 Themen dieser Ausgabe sind u. a. Ubuntu unter Windows ausprobiert Seite 3 Microsoft hat auf der Entwicklerkonferenz Build 2016 einigermaßen überraschend verraten, dass in zukünftigen Windows-Versionen die Bash sowie eine ganze Sammlung von Linux-Tools auf der Basis von Ubuntu 14.04 integriert werden soll. Der Artikel gibt einen ersten Eindruck des „Windows-Subsystems für Linux“, das Microsoft bereitstellt, um Ubuntu ohne Virtualisierung unter Windows laufen zu lassen. (weiterlesen) Linux-Distributionen im Vergleich – eine etwas andere Auswahl Seite 8 In dem Artikel werden eine Reihe von Linux-Distributionen vorgestellt, die nicht so bekannt sind wie die klassischen „großen“ Distributionen oder nicht so häufig verwendet werden, weil sie entweder für spezielle Anwendungen oder für einen besonderen Benutzerkreis konzipiert sind. Ziel ist es, diese Distributionen ein bisschen näher kennenzulernen, damit man weiß, was zur Verfügung steht, wenn man einmal etwas ganz bestimmtes braucht. (weiterlesen) Audacity 2.1 – Teil I Seite 21 Aus verschiedenen Gründen ist Audacity der beliebteste freie Audio-Editor. Im Internetzeitalter hat man sich daran gewöhnt, dass viele Programme kostenlos verfügbar sind, aber dennoch eine hohe Professionalität aufweisen. In die Riege der besten Open-Source-Werkzeuge reiht sich auch Audacity ein. Ob man nun die Schallplatten- oder Kassettensammlung digitalisieren, Videos nachvertonen oder das eigene Gitarrenspiel oder den Bandauftritt aufnehmen und bearbeiten möchte – all das ist mit Audacity möglich.

Just add -fsanitize=address to the compiler flags in GCC/CLANG. 7 FIND BUGS WITH ASAN ./configure CFLAGS="-fsanitize=address -g" \ CXXFLAGS="-fsanitize=address -g" \ LDFLAGS="-fsanitize=address" make make check 8 WHAT IS ASAN DOING? Shadow memory tracking which memory areas are valid. Finds out of bounds access (read/write) and use aer free bugs (and other less common issues). 9 OUT OF BOUNDS READ #include <stdio.h> int main() { int a[2] = {3,1}; int i = 2; printf("%i\n", a[i]); } 10 USE AFTER FREE #include <stdio.h> #include <stdlib.h> int main() { char *c = calloc(10,1); printf("%i\n", c[0]); free(c); printf("%i\n", c[1]); } 11 MISSION: TEST EVERYTING WITH ASAN Every project using C/C++ code should test with ASAN. -

Gtk2-Perl: an Introduction
Gtk2-Perl: An Introduction Gtk2-Perl: An Introduction Or How I Learned to Stop Worrying and Make Things Pretty Scott Paul Robertson http://spr.mahonri5.net [email protected] May 9, 2007 Gtk2-Perl: An Introduction Background What is Gtk2-Perl? Gtk2-Perl is the set of Perl bindings for Gtk2, and related libraries1. These allow you to code Gtk2 and Gnome applications in Perl. Gtk2-Perl is fairly easy to get started using, but has a few hang ups that can be difficult to discover, or sometimes the documentation is just not there. The developers are aware of the issue, and encourage users to provide documentation, reference guides, or tutorials. 1Glade, Glib, etc Gtk2-Perl: An Introduction Background Online Documentation There are a few major online sources for Gtk2-Perl documentation: ◮ Gtk2-Perl Tutorial - The offical tutorial. ◮ Gtk2-Perl Study Guide - Another excellent tutorial/reference ◮ Introduction to GUI Programming with Gtk2-Perl - As it says, it’s a good introduction to gui programming in general. ◮ Gtk2-Perl Pod Documentation - You might have these as man pages as well, very helpful. Gtk2-Perl: An Introduction Basic Application A Simple Window We’ll start with an example of a simple single button application. First we have to initalize Gtk2: #!/usr/bin/perl -w use strict; use Gtk2 ’-init’; use readonly TRUE => 1; use readonly FALSE => 0; ◮ The ’-init’ prepares the Gtk2 environment, otherwise we would have to do it ourselves later. ◮ Defining the constants is very helpful for code readability later. Gtk2-Perl: An Introduction Basic Application A Simple Window Now we set up the window object and a button. -
