Arm

In human anatomy, the arm is the upper limb of the body, comprising regions between the glenohumeral joint (shoulder joint) and the elbow joint. In common usage the arm extends to the hand. It can be divided into the upper arm (brachium), the forearm (antebrachium), and the hand (manus). Anatomically the shoulder girdle with bones and corresponding muscles is by definition a part of the arm. The Latin term brachium may refer to both the arm as a whole or to the upper arm on its own.

Anatomy

Bones

The humerus is one of the three long bones of the arm. It joins with the scapula at the shoulder joint and with the other long bones of the arm, the ulna and radius at the elbow joint. The elbow is the hinge joint between the end of the humerus and the ends of the radius and ulna. The humerus cannot be broken easily. Its strength allows it to handle loading up to 300 pounds (140 kg).

Muscles

The arm is divided by a fascial layer (known as lateral and medial intermuscular septa) separating the muscles into two osteofascial compartments: the anterior and the posterior compartments of the arm. The fascia merges with the periosteum (outer bone layer) of the humerus. The compartments contain muscles which are innervated by the same nerve and perform the same action.

Tor (anonymity network)

Tor is free software for enabling anonymous communication. The name is an acronym derived from the original software project name The Onion Router, however the correct spelling is "Tor", capitalizing only the first letter. Tor directs Internet traffic through a free, worldwide, volunteer network consisting of more than seven thousand relays to conceal a user's location and usage from anyone conducting network surveillance or traffic analysis. Using Tor makes it more difficult for Internet activity to be traced back to the user: this includes "visits to Web sites, online posts, instant messages, and other communication forms". Tor's use is intended to protect the personal privacy of users, as well as their freedom and ability to conduct confidential communication by keeping their Internet activities from being monitored.

Onion routing is implemented by encryption in the application layer of a communication protocol stack, nested like the layers of an onion. Tor encrypts the data, including the destination IP address, multiple times and sends it through a virtual circuit comprising successive, randomly selected Tor relays. Each relay decrypts a layer of encryption to reveal only the next relay in the circuit in order to pass the remaining encrypted data on to it. The final relay decrypts the innermost layer of encryption and sends the original data to its destination without revealing, or even knowing, the source IP address. Because the routing of the communication is partly concealed at every hop in the Tor circuit, this method eliminates any single point at which the communicating peers can be determined through network surveillance that relies upon knowing its source and destination.

List of ARM microarchitectures

This is a list of microarchitectures based on the ARM family of instruction sets designed by ARM Holdings and 3rd parties, sorted by version of the ARM instruction set, release and name. ARM provides a summary of the numerous vendors who implement ARM cores in their design.Keil also provides a somewhat newer summary of vendors of ARM based processors. ARM further provides a chart displaying an overview of the ARM processor lineup with performance and functionality versus capabilities for the more recent ARM core families.

ARM11

ARM11 is a group of 32-bit RISC ARM processor cores licensed by ARM Holdings.

Overview

The ARM11 microarchitecture (announced 29 April 2002) introduced the ARMv6 architectural additions which had been announced in October 2001. These include SIMD media instructions, multiprocessor support and a new cache architecture. The implementation included a significantly improved instruction processing pipeline, compared to previous ARM9 or ARM10 families, and is used in smartphones from Apple, Nokia, and others. The initial ARM11 core (ARM1136) was released to licensees in October 2002.

The ARM11 family are currently the only ARMv6-architecture cores. There are, however, ARMv6-M cores (Cortex-M0 and Cortex-M1), addressing microcontroller applications; ARM11 cores target more demanding applications.

Differences from ARM9

In terms of instruction set, ARM11 builds on the preceding ARM9 generation. It incorporates all ARM926EJ-S features and adds the ARMv6 instructions for media support (SIMD) and accelerating IRQ response.

Human (Skye Sweetnam song)

"Human" is the fourth single released by Canadian pop rock singer Skye Sweetnam. The song is the lead single released by Sweetnam off of her second album Sound Soldier. The song was produced by production group The Matrix.

Song information

The song was released on her MySpace as a sneak peek, while the full version was leaked to the internet on September 8, 2007. Sweetnam performed the song while she toured across Canada in October and November 2007 as the opening act for Kalan Porter and then on her own tour with Faber Drive. She also performed "Human" as part of her setlist on the 2007 School Rocks Canada tour. The new song was released through EMI, quelling rumors of Sweetnam being dropped from Capitol Records.

Music video

The music video, directed by Sean Wainsteim, was inspired by the film Tank Girl. Sweetnam is in a wasteland where she's surrounded by "junk people" while singing about how "we're only human". She also leads the group of "junkies" in a dance sequence and is followed while driving a bulldozer. The ending of the video has a comic book-style animation sequence. This was drawn by comic book artist Cameron Stewart.
