Root Android : rooter c'est quoi au juste ?

Root : Qu'est-ce que ça veut dire ? C'est quoi au juste ? Dans tout système d'exploitation, il existe au moins un utilisateur suprême qui possède tout les droits sur le système, c'est à dire que ce dernier n'a aucune restriction. Il peut donc tout faire, y compris des bêtises pouvant endommager le système. Cet utilisateur suprême s'appelle administrateur (dans l'univers Windows ) alias "admin" et comme le système android fait partie de la famille GNU/Linux (système d'exploitation libre), cet utilisateur suprême est "Root" ou "Super Utilisateur" alias "SU" pour "SuperUser".

Ca permet de faire quoi concrètement à mon système ? Être en Root permet d'avoir le luxe de modifier les paramètres sensibles du système android. Il permet entre autre : d'installer des programmes nécessitant la mise en root tel que les applications de capture d'écran...de supprimer des applications pré-installée lors de l'achatde changer la police d'écriturede modifier la fréquence du processeur pour tirer meilleur profit de la batterie ou augmenter l'autonomie pour jouer à des jeuxde mettre un thème Halloween, Noel Saint valentin et plein d'autrede changer l'écran de chargement lors de l'allumaged'utiliser des logiciels spécifiques (sauvegarde par exemple), avant de mettre comme certains le font une version optimisée (qu'on appelle dans le jargon une rom custom) ou de changer le kerneld'épater les copains

D-Link Cloud Routers

Z-Wave is a wireless communications protocol designed for home automation, specifically to remotely control applications in residential and light commercial environments. The technology uses a low-power RF radio embedded or retrofitted into home electronics devices and systems, such as lighting, home access control, entertainment systems and household appliances.

Overview

Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. Tor provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy. Individuals use Tor to keep websites from tracking them and their family members, or to connect to news sites, instant messaging services, or the like when these are blocked by their local Internet providers. Tor's hidden services let users publish web sites and other services without needing to reveal the location of the site. Individuals also use Tor for socially sensitive communication: chat rooms and web forums for rape and abuse survivors, or people with illnesses.

Light-emitting diode

A light-emitting diode (LED) is a semiconductor light source.[3] LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. Introduced as a practical electronic component in 1962,[4] early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness. When a light-emitting diode is forward-biased (switched on), electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence and the color of the light (corresponding to the energy of the photon) is determined by the energy gap of the semiconductor. LEDs are often small in area (less than 1 mm2), and integrated optical components may be used to shape its radiation pattern.[5] LEDs present many advantages over incandescent light sources including lower energy consumption, longer lifetime, improved robustness, smaller size, and faster switching. LEDs powerful enough for room lighting are relatively expensive and require more precise current and heat management than compact fluorescent lamp sources of comparable output. Light-emitting diodes are used in applications as diverse as aviation lighting, automotive lighting, advertising, general lighting, and traffic signals. LEDs have allowed new text, video displays, live video, and sensors to be developed, while their high switching rates are also useful in advanced communications technology. Infrared LEDs are also used in the remote control units of many commercial products including televisions, DVD players, and other domestic appliances.

Japan collab transmits record data speeds on terahertz waves

Researchers from Japan-based semiconductor manufacturer Rohm, together with a team from Osaka University, have come up with a chip that, in experiments, has achieved a wireless data transmission speed of 1.5 gigabits per second. This is a record breaker as the world's first terahertz wireless communication achieved with a small semiconductor device. The chip’s ability to transmit at such a quick speed is not the end of the story. Even higher transmission speeds of up to 30 Gbps may be possible in the future, according to reports.

“Research into terahertz technology utilising Terahertz frequency (100GHz-10THz) is now receiving increasing attention around the world,” according to an Osaka University publication

The 620325 Stirling Engine by Thames and Kosmos uses renewable energy from the sun to drive a generator, which charges a rechargeable battery to power an electric car.

Power a Car with Solar Generated Electricity       Discover the Stirling engine, a simple, clean and efficient energy technology that is quickly becoming a viable source of electricity as the availability of fossil fuels declines. The Stirling engine in this kit uses renewable energy from the sun to drive a generator, which charges a rechargeable battery to power an electric car. Named after its inventor, Robert Stirling, the original Stirling engine dates back almost 200 years. Today, high-tech Stirling engines are being used in arrays of giant mirrored solar collectors and common applications like compact generators. NASA is even working on using Stirling engines to power a human outpost on the moon!Like a steam engine, a Stirling engine is a heat engine that converts heat energy into mechanical work, usually to drive a generator that then converts the mechanical energy into electricity. But instead of water and steam, the Stirling engine uses a permanently enclosed volume of gas, such as air or helium, to perform the mechanical work. Stirling engines are highly efficient, can operate very quietly, and can use many different sources of heat: combustion of fuels, nuclear fission, geothermal, or solar heat, as this model uses. The Stirling engine in this kit is located in acharging station with a mirrored parabolic dish. The dish focuses the sun’s rays onto the cylindrical glass bulb of the Stirling engine to heat it up. The air inside the bulb heats up and pushes a piston, which turns an electric generator. The generator produces electricity that charges a rechargeable battery in the car. The car runs on an electric motor powered by the battery.The kit includes the charging station with a beta type Stirling engine, the electric car, and a full-color, 64-page manual.

Near field communication (NFC) is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimetres. Present and anticipated applications include contactless transactions, data exchange, and simplified setup of more complex communications such as Wi-Fi.[1] Communication is also possible between an NFC device and an unpowered NFC chip, called a "tag".[2]

NFC standards cover communications protocols and data exchange formats, and are based on existing radio-frequency identification (RFID) standards including ISO/IEC 14443 and FeliCa.[3] The standards include ISO/IEC 18092[4] and those defined by the NFC Forum, which was founded in 2004 by Nokia, Philips and Sony, and now has more than 160 members. The Forum also promotes NFC and certifies device compliance.[5

Pourquoi nous ne vendons pas de pub

À nous deux, Brian et moi avons passé 20 ans chez Yahoo, travaillant dur au bon fonctionnement du site. Et aussi oui, travaillant dur à vendre de la pub, parce que c’était ce que Yahoo faisait : recueillir des données, la publication de pages et la vendre de la publicité.

Nous avons été témoins du déclin de Yahoo tandis que continuaient à grandir la taille et l’audience de Google, vendeur d’espaces publicitaires plus efficace et plus rentable. Google savait ce que les utilisateurs recherchaient, pouvant ainsi recueillir plus efficacement des données sur ces derniers et afficher de meilleures publicités.

open-source social networking project Diaspora

if the team is half as good at building software as it is at building hype, there might be something interesting in the upcoming release, and maybe even a viable business.

The big challenge is that the enterprise developer world isn't screaming out for an open-source Facebook, nor are consumers really looking to run their own instances of social networks. What they really want is for Facebook to take privacy more seriously
