Monitor: An internet of airborne things THE spread of mobile phones in developing countries in the past decade has delivered enormous social and economic benefits. By providing a substitute for travel, phones can make up for bad roads and poor transport infrastructure, helping traders find better prices and boosting entrepreneurship. But although information can be delivered by phone—and, in a growing number of countries, money transferred as well—there are some things that must be delivered physically. For small items that are needed urgently, such as medicines, why not use drone helicopters to deliver them, bypassing the need for roads altogether? That, at least, was the idea cooked up last year at Singularity University, a Silicon Valley summer school where eager entrepreneurs gather in the hope of solving humanity’s grandest challenges with new technologies. The plan is to build a network of autonomously controlled, multi-rotor unmanned aerial vehicles (UAVs) to carry small packages of a standardised size.

Dragrove - Generic gateway for internet of things Dragrove is an open source based generic gateway for internet of things. It combines Dragino (Easy Internet Access, powerful CPU, Linux system), Arduino compatible interface board (monitoring and controlling the physical world), and RF networks like X-Bee. Dragino MS12 is a wifi/linux enabled appliance for MCU projects. The goal of the Dragino is to solve the connectivity problem and greatly enhance microcontroller products. The Arduino compatible daughter board provides plug and play interface like Grove, it also provides 8 IO terminals for developers to easily create Internet of things projects, Robotics, Smart Home, Wireless Sensor Networks and many beyond. Features: Open WRT based Arduino Compatible IO extension bus ready for hacking Build-in Grove connector XBee wireless module socket IoT (internet of things) gateway Remore firmware update Dual NIC enabled wifi router User-friendly admin Interface Documents: Wiki
Rethinking personal data | World Economic Forum-Rethinking personal data Report: Unlocking the Value of Personal Data: From Collection to Usage, February 2013 Unlocking the Value of Personal Data: From Collection to Usage, prepared in collaboration with the Boston Consulting Group, examines the need for new approaches in the policies which enable the managing of personal data in ways that are flexible, adaptive and contextually driven. The report highlights outcomes from a nine month, multistakeholder, global dialogue on how the principles for using personal data may need to be refreshed to ensure they protect the rights of individuals, unlock socio-economic value and are fit for the complexities of a hyperconnected world. A key insight from the report notes that the age of Big Data creates both new opportunities and risks, particularly as they relate to the privacy of individuals. The report calls for the importance of establishing an updated set of principles and the means to uphold them in a hyperconnected world. Who owns personal data?
Graver un bootloader sur ATMEGA328P-PU | The Polyscope Pour ceux qui programment sur Arduino, l’envie vient tôt ou tard de porter le montage hors de la carte Arduino pour des raisons de consommation, de place ou de coût. De nombreux conseils et tutoriaux existent et après m’y être frotté, un de plus ne sera pas de trop, notamment si vous aussi vous n’avez pas trop compris cette histoire d’horloge interne et d’oscillateur externe … Depuis le début Pour rappel, l’ATMEGA328P-PU est la puce au coeur de l’Arduino UNO notamment (encadrée en rouge sur l’image plus bas, on repère l’encoche à droite de la puce pour l’orienter correctement). On doit donc graver cette séquence pour pouvoir utiliser l’ATMEGA. Les étapes 1 – Utiliser l’Arduino comme ISP (In System Programmer) On charge un programme particulier dans l’Arduino pour qu’il devienne l’interface capable de graver notre ATMEGA. 2 – Charger un nouveau matériel dans l’IDE Arduino Le matériel ATMEGA autonome n’est pas listé par défaut dans les types de carte (menu Outils). 3 – Réaliser le circuit
