"The Fairphone is a modular handset designed with repairability and ethical sourcing of its materials as headline features. It sold 60,000 units. Amazingly, for what sounds like a nerd-phone, almost half of those buyers had never owned a smartphone before. Now the Fairphone 2 is launching, and with a totally-new, in-house design. The new phone is even easier to repair, and because it was wholly designed by the FairPhone team, its supply chain is even more responsible than ever. The Fairphone is thicker than the latest iPhone or Samsung flagship, but that's the point. Instead of packing everything into a tiny case and keeping it there with glue, the Fairphone is designed to be taken apart. The lightweight magnesium frame supports modules that can be easily replaced by the user. "We have designed it with an aim to last three to five years, looking at making it robust and modular-for repairability," says Fairphone's chief communications officer, Tessa Wernink. "Obviously how long it lasts depends quite heavily on the user, so what we as a company are doing is offering an ecosystem around the phone that supports long-lasting use, first-hand or second-hand." Inside the case (itself one of several options) you'll find the core unit, containing all the chips and radios; a replaceable battery pack; a display that can be snapped off and replaced without any tools (not even a screwdriver); a receiver unit, which contains the front camera, sensors; the headset connector and microphones; a speaker/vibrator unit; and a camera module. These modules are designed to balance manufacturing complexity with repairability. For instance, the display comes as a standalone unit, but less-vulnerable components are bundled into one module. The camera, which people are most likely to upgrade as better versions become available, is also housed in its own module. That way you don't need to toss out your whole phone just to get a better camera. "In fact, the motto from the maker mo

"Actividades con Software Libre es, además de un CD interactivo, una propuesta de trabajo: una invitación a integrar la clase de Informática con temas curriculares, al trabajo cooperativo de profesores de Informática y docentes de otras áreas, a incorporar de una manera articulada la tecnología en el aula. Los docentes podrán recorrer textos con conceptos teóricos y metodológicos sobre el movimiento del Software Libre en informática, en internet y en educación; incorporar sugerencias de actividades para realizar en clase en todos los niveles del sistema educativo, y conocer programas, herramientas y manuales."

"Cuatro módulos con conceptos básicos del movimiento del Software Libre, sus aplicaciones en internet y en informática y reflexiones sobre su valor educativo. Lecturas, documentos y otros materiales para abordar estas temáticas y capacitarse sobre el mundo del Software Libre."
