"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

SIIA's 2011 Vision K-20 finds schools should do a better job of meeting students' personalized needs and provide higher-caliber assessment tools. The Software & Information Industry Association (SIIA) has released the results of its fourth annual national education survey.

"... In addition to serving as a great explanatory example of the potential danger of AI, I have realized that paperclip maximizer is also a perfect allegory for capitalism. Where the artificial intelligence sought to maximize paperclips, the capital maximizer seeks to maximize capital. ... While this story of the capital maximizer might strike some as the anti-capitalist rantings of socialist idealism, it is not meant as such. Capitalism is the most powerful machine that humans have ever created. It can realize the benefits of technological progress and leverage them to improving the human condition better than any other economic system yet devised. The problem is in viewing the growth of capital as an ends and not a means. If we do not demand that our systems maximize the well-being of humans and the environment which sustains us, then all is lost."

"This book is a collection of homework problems for use in an introductory physics course. It is a work in progress, currently complete through mechanics and electromagnetism. There is a complete set of ancillary materials, including solutions and an online answer checker. If you're an instructor, you can use these problems as a plug-in replacement for the ones in a commercial textbook, thus insulating yourself from common hassles associated with using the problems from a commercial text. For example, you can change books without having to redo all your problem sets, or you can tell your students that they can use any edition of a particular text."

"¿Sabría usted reconocer una trampa del progreso si la tuviese delante de los ojos? "Si progresar, de acuerdo con el diccionario, es hacer adelantamientos en una materia, lo procedente es analizar si estos adelantamientos en una materia implican un retroceso en otras y valorar en qué medida lo que se avanza justifica lo que se sacrifica."No nos hallamos dentro de un "mundo-máquina", una suerte de laboratorio/ fábrica gigantesco donde todo parece predecible y controlable, sino en una biosfera intrincadamente compleja, con redes de causa-efecto a veces inescrutables, con sorpresas sistémicas, efectos de umbral, irreversibilidades y sinergias múltiples."No sé los horrores que nos aguardan" -escribía Bertrand Russell en 1961- "pero nadie puede dudar de que, a menos que se haga algo radical, el hombre de la era científica está sentenciado. En el mundo en que vivimos existe un activo y dominante deseo de muerte que, hasta ahora, en todas las crisis, ha podido más que la cordura. Si hemos de sobrevivir, tal estado de cosas no debe continuar" (¿Tiene el hombre un futuro?, Aguilar, Madrid 1962)."Las dos formas en que la humanidad puede autodestruirse -la guerra civil a escala mundial o la devastación del medio ambiente- están convergiendo rápidamente" Si hoy la prolongación del desarrollo lleva al colapso ecológico-social, progreso sería ganar cierto control sobre el vehículo embalado para ser capaces de detenernos. Momento de parar, proclamaba el artista canario César Manrique en su manifiesto de 1985; Parar en seco, insiste dramáticamente el escritor colombiano William Ospina en 2017 (Navona Editorial, Barcelona). Frenar o al menos ralentizar para variar el rumbo -porque prolongar la trayectoria actual nos precipita al abismo. ¿Está a nuestro alcance el recurso al freno de emergencia?¿Qué puede significar progreso hoy, habida cuenta de los fenómenos de retroprogreso y contraproductividad que antes analizamos someramente?
