Sawzall (tool)
A reciprocating saw is a type of machine-powered saw in which the cutting action is achieved through a push-and-pull ("reciprocating") motion of the blade. The original trade name Sawzall is often used in the United States, where Milwaukee Electric Tool first produced a tool of this type in 1951. The term is commonly applied to a type of saw used in construction and demolition work. This type of saw, also known as a hognose or recip saw, has a large blade resembling that of a jigsaw and a handle oriented to allow the saw to be used comfortably on vertical surfaces. The typical design of this saw has a foot at the base of the blade, similar to that of a jigsaw. The user holds or rests this foot on the surface being cut so that the tendency of the blade to push away from or pull towards the cut as the blade travels through its movement can be countered. Design Designs range widely in power, speed, and features, from less powerful portable, handheld models that are usually shaped ...

Sawzall (programming Language)
Sawzall is a procedural domain-specific programming language, used by Google to process large numbers of individual log records. Sawzall was first described in 2003, and the szl runtime was open-sourced in August 2010. However, since the MapReduce table aggregators have not been released, the open-sourced runtime is not useful for large-scale data analysis of multiple log files off the shelf. Sawzall has been replaced by Lingo (logs in Go) for most purposes within Google. Motivation Google's server logs are stored as large collections of records (Protocol Buffers) that are partitioned over many disks within GFS. In order to perform calculations involving the logs, engineers can write MapReduce programs in C++ or Java. MapReduce programs need to be compiled and may be more verbose than necessary, so writing a program to analyze the logs can be time-consuming. To make it easier to write quick scripts, Rob Pike et al. developed the Sawzall language. A Sawzall script runs within the ...
