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

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.

One of the main hardware difference between Android devices is he GPU which is part of the SoC (System On a Chip / Chipset) powering the handset. There’s currently three big players in the market today: Qualcomm’s SnapDragon SoC with the Adreno 200 GPU, TI OMAP 3XXX with the Power VR SGX 530/535 and finally Samsung’s Hummingbird (S5PC110A01) with a PowerVR SGX540 GPU all three of them feature a CortexA8 CPU core.

AMD Z430 GPU

have shown up to a %500 increase in performance in some bechnmarks when homemade/tweaked drivers where used instead of the ones supplied with the retail device.

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
