Chipmunk
Chipmunks are small, striped rodents of the family Sciuridae. Chipmunks are found in North America, with the exception of the Siberian chipmunk which is found primarily in Asia.
Taxonomy and systematics
Chipmunks may be classified either as a single genus, Tamias (Greek: ταμίας), or as three genera: Tamias, which includes the eastern chipmunk; Eutamias, which includes the Siberian chipmunk; and Neotamias, which includes the 23 remaining, mostly western, species. These classifications are arbitrary, and most taxonomies over the twentieth century have placed the chipmunks in a single genus. However, studies of mitochondrial DNA show that the divergence between each of the three chipmunk groups is comparable to the genetic dissimilarity between Marmota and Spermophilus.

Chipmunk (software)
Chipmunk2D is a 2-dimensional real-time rigid body physics engine written by Scott Lembcke that is designed to be portable, lightweight, fast, and easy to use. Prior to version 7, two main versions of the library existed. Chipmunk2D Free was written purely in C99, and freely available under the terms of the MIT License. Chipmunk2D Pro was a proprietary upgrade designed for development on mobile devices. It included several high-level subroutines in Objective-C, and floating-point optimizations for the ARM processor. However, after version 7 the project was fully open-sourced.
Aside from Objective-C, there are official bindings for Ruby, and third party interfaces exist for Python,Haskell,OCaml, and others. Chipmunk is endorsed by a number of game libraries, including Aerosol, Gosu, and Cocos2d.
Features
Chipmunk supports multiple collision primitives attached to one rigid body, and bodies may be joined by constraints. It has a flexible collision detection system with layers, exclusion groups and collision callbacks. Callbacks are defined based on user definable "collision types" and may reject collisions and even override the calculation of friction and elasticity coefficients.

Donna (Ritchie Valens song)
"Donna" is a song sung by Ritchie Valens, featuring the 50s progression. The song was released in 1958 on Del-Fi Records. It reached #2 on the Billboard Hot 100 chart the following year, becoming Valens' highest-charting single. It was written as a tribute to his high school sweetheart Donna Ludwig.
Valens' version
The song was recorded on December 16, 1958 at the Gold Star Studios in Los Angeles. Bob Keene is listed as being the leader of the session which included Earl Palmer on drums, Buddy Clark on bass, Valens, Rene Hall, Irving Ashby and Carole Kaye on guitars.
"Donna", the second Ritchie Valens single released, was the A side of the influential and more famous song "La Bamba". This single was only one of three, along with the previous single ("Come On, Let's Go"/"Framed" – Del-Fi 4106) and the follow-up ("Fast Freight"/"Big Baby Blues" – Del-Fi 4111) ever released in Valens's lifetime. Original Del-Fi pressings of "Donna"/"La Bamba" include black and sea green labels with circles, later replaced with solid sea green or solid dark green labels. Early 1960s pressings have black labels with sea green "sawtooth" outer edge.
