Njegova namje- na bila je interakcija i prikaz web stranica umjesto podloge. Iako to nije osobito zaæivjelo, potreba prikaza nekog sadræaja na toj lokaciji je ostala. SreÊom, razvoj zahtjevnog softvera je sporiji od napretka tehnologije, Mooreova zakona i snage raËunala, pa tako uvijek imamo neku procesorsku rezervu koju moæemo potroπiti na zgodne dodatke naπoj radnoj povrπini. Citirajmo opis jednog od tih programa - "simbiotski spoj ljepote (eye-candy) i besko- risnosti".

  • Resumen Los Widgets, Pequeñas Aplicaciones De Escritorio, Se Han Convertido En Objeto De Estudio Para Este Trabajo
    Resumen Los widgets, pequeñas aplicaciones de escritorio, se han convertido en objeto de estudio para este trabajo. Se ha analizado y estudiado su entorno, funcionamiento y estructura. Como resultado se ha obtenido una definición del concepto de widget, con diferentes ejemplos prácticos, y una comparativa entre las compañías más destacadas que ofrecen widgets (Apple, Microsoft, Yahoo!, Google y Opera) así como de las diferencias a nivel de estructura e implementación que se encuentran entre sus widgets. En el apartado de estudio también se ha dado atención a los usuarios de estas aplicaciones, explicando cuáles son sus necesidades, costumbres y posibilidades de elección en este campo. Otro de los apartados trata de cubrir algunas de las tecnologías más relevantes implicadas en la creación posterior de un widget, la aplicación Dashcode, el lenguaje de programación JavaScript, y los canales RSS. El tema de los widgets también ha dado lugar a todo un apartado de desarrollo. Se ha creado un widget para la plataforma de Apple, Macintosh. El widget proporciona al usuario las últimas noticias y resultados del mundo deportivo, concretamente de dos deportes, fútbol y baloncesto. Todas las fases del proceso de creación del widget han sido descritas de principio a fin, desde los bocetos iniciales a la puesta en funcionamiento, pasando por el prototipado e implementación. De manera adicional, también se ha incluido un apartado dedicado al diseño de widgets, con algunas y consejos a tener en cuenta al diseñar widgets en general. Por último se han vertido diferentes conclusiones fruto del presente trabajo y de la reflexión sobre la situación actual de este campo, sin olvidar los aspectos a mejorar, las áreas en que se está trabajando y las perspectivas de futuro.

AVEZ-VOUS BESOIN DE CE LIVRE ? Vous devriez lire ce livre si vous voulez développer pour KDE. Nous utilisons le terme développement très largement pour couvrir tout ce qui peut conduire à un changement dans le code source, ce qui inclut : Soumettre une correction de bogue Écrire une nouvelle application optimisée par la technologie KDE Contribuer à un projet existant Ajouter de la fonctionnalité aux bibliothèques de développement de KDE Dans ce livre, nous vous livrerons les bases dont vous avez besoin pour être un développeur productif. Nous décrirons les outils que vous devrez installer, montrer comment lire la documentation (et écrire la vôtre propre, une fois que vous aurez créé la nouvelle fonctionnalité !) et comment obtenir de l'aide par d'autres moyens. Nous vous présenterons la communauté KDE, qui est essentielle pour comprendre KDE parce que nous sommes un projet « open source », libre (gratuit). Les utilisateurs finaux du logiciel n'ont PAS besoin de ce livre ! Cependant, ils pourraient le trouver intéressant pour les aider à comprendre comment les logiciels complexes et riches en fonctionnalités qu'ils utilisent ont vu le jour. 3 2. LA PHILOSOPHIE DE KDE Le succès de KDE repose sur une vue globale, que nous avons trouvée à la fois pratique et motivante. Les éléments de cette philosophie de développement comprennent : L'utilisation des outils disponibles plutôt que de ré-inventer ceux existants : beaucoup des bases dont vous avez besoin pour travailler font déjà partie de KDE, comme les bibliothèques principales ou les « Kparts », et sont tout à fait au point.

  • Translate's Localization Guide
    Translate’s Localization Guide Release 0.9.0 Translate Jun 26, 2020 Contents 1 Localisation Guide 1 2 Glossary 191 3 Language Information 195 i ii CHAPTER 1 Localisation Guide The general aim of this document is not to replace other well written works but to draw them together. So for instance the section on projects contains information that should help you get started and point you to the documents that are often hard to find. The section of translation should provide a general enough overview of common mistakes and pitfalls. We have found the localisation community very fragmented and hope that through this document we can bring people together and unify information that is out there but in many many different places. The one section that we feel is unique is the guide to developers – they make assumptions about localisation without fully understanding the implications, we complain but honestly there is not one place that can help give a developer and overview of what is needed from them, we hope that the developer section goes a long way to solving that issue. 1.1 Purpose The purpose of this document is to provide one reference for localisers. You will find lots of information on localising and packaging on the web but not a single resource that can guide you. Most of the information is also domain specific ie it addresses KDE, Mozilla, etc. We hope that this is more general. This document also goes beyond the technical aspects of localisation which seems to be the domain of other lo- calisation documents.

  • Examination of Gdesklets Dependencies
    Examination of gDesklets Dependencies S.Fourmanoit M.Pirnat Montr´eal and Cleveland, March 20, 2005. 1 Foreword This document tries to determine what is, at the time of writing, the minimal set of dependencies required to compile and run gDesklets on an up-to-date desktop system. The author spent several hours testing, as systematically as time permitted, all possible avenues, following often-contradictory indications provided by official documentation, emails, forums, automated build source, how-tos and bug reports. It is not by any means a canonical reference on gDesklets installation, merely a report of what seems the current state of this software regarding its dependency tree. 2 Test system Most of the gDesklets user base uses Linux, although the software is also sup- ported on numerous other platforms; it is even being actively ported to Win- dows. For the sake of this report, the author built a reference platform using Gentoo Linux. The base system was built from the Gentoo 2004.3 x86 Stage 1 tarball, and all the default profile USE flags were cautiously adjusted to be1: Use flag Description +mmx Adds support for optimizations for Pentium MMX and Athlon class processors +3dnow Adds support for 3dnow multimedia processor instructions +x86 indicates that architecture is x86 +nptl Enable support for Native POSIX Threads Library +nptlonly Remove suport for previous pthread interface -oss Adds support for OSS (Open Sound System) -apm Adds APM (Advanced Power Management) support -arts Adds support for aRts: the KDE sound daemon -avi Adds Win32 AVI support and also adds avifile (Library for avi) support 1Flags in red were selected, while those in blue were not.

LUCRE stands for Local and User-Created Services. The project is part of the Flexible Services research programme, one of the programmes of the Strategic Centre for Science, Technology and Innovation in the ICT field (TIVIT) and funded by Tekes (the Finnish Funding Agency for Technology and Innovation) and the participating organizations. The Flexible Service Programme creates service business activity for global markets. The programme has the aim of creating a Web of Services. The programme creates new types of ecosystems, in which the producers of services, the people that convey the service and the users all work together in unison. As part of such ecosystems, LUCRE will develop an easy-to-use, visual service creation platform to support the creation of context aware mobile services. The goal is to support user-driven open innovation: the end- users (people, local businesses, communities) will be provided with tools to compose new services or to modify existing ones. The service creation platform will build on the technology of existing mashup tools, widget frameworks, and publish/subscribe mechanisms.

  • Linux En Desktop Y Su Entorno Gráfico
    LINUX EN DESKTOP Charla realizada el 02/06/2009 Lic. Mariano Acciardi – Instructor grupo CATI http://www.marianoacciardi.com.ar Esta charla constituye un complemento de la anterior realizada el año pasado que puede encontrarse en http://www.marianoacciardi.com.ar/textos_gnulinux/bienvenidos.pdf , pero centránda en esta oportunidad en las particularidades del entorno gráfico y la disponibilidad de aplicaciones. Historia e Introducción Erase una vez un Sistema Operativo, poco amigable, de tristes consolas de texto, alejado de los usuarios.... Por fortuna, gracias a Mandriva (ex mandrake) y Ubuntu ello cambió y bastante. Afortunadamente hoy un usuario medio de una PC de escritorio no debería tener demasiadas dificultades para utilizar GNU/LINUX. Los instaladores han evolucionado radicalmente a apartir de knoppix y Ubuntu y esos cambios se han portado a las grandes distribuciones tradicionales como Debian. El reconocimiento de hardware no es ya un problema. La rápida evolución del kernel no ha sido indiferente en esta mejora. Hoy prácticamente no hay hardware que no sea reconocido por el kernel. Y la mayoría de los dispositivos tienen drivers genéricos aportados por la comunidad que funcionan OK. Algunas empresas se niegan aún inexplicablemente a liberar el código de sus drivers. Sin embargo siempre hay genios hackers que realizan ingeniería inversa del código y finalmente logran armar los drivers correspondientes. Este fue una de las mayores limitaciones de las primeras distribuciones, hoy en gran parte, completamente superada. La otra falsa limitación que se profesa por ignorancia es que no existen muchas aplicaciones en GNU/LINUX como si existen en Windows. Es una realidad que hay más aplicaciones para Windows que para Linux, sin embargo si tratamos de hacer un balance entre calidad y cantidad, por lejos salen ganando las aplicaciones para LINUX, hechas por hackers enamorados de la programación y por tanto adscriptos a la ética de programar bien.
