Less children go outside and engage in active play as technology, such as television and video games, keep children indoors. Rather than walking or biking to a bus-stop or directly to school, more school-age children are driven to school by their parents, reducing physical activity. As family sizes decrease, the childrens pester power, their ability to force adults to do what they want, increases. This ability enables them to have easier access to calorie-packed foods, such as candy and soda drinks. The social context around family meal-time plays a role in rates of childhood obesity

Social policies
Different communities and nations have adopted varying social practices and policies that are either beneficial or detrimental to childrens physical health. These social factors include:
the quality of school lunches
the emphasis of schools on physical activity
access to vending machines and fast-food restaurants
prevalence of and access to parks, bike paths, and sidewalks
government subsidies for corn oil and sugar
advertising of fast-food restaurants and candy
prices of healthy and unhealthy foods
access to fresh, healthy, and affordable food

Advertising
Advertising of unhealthy foods correlates with childhood obesity rates. In some nations, advertising of candy, cereal, and fast-food restaurants is illegal or limited on childrens television channels. The media defends itself by blaming the parents for yielding to their childrens demands for unhealthy foods. Socioeconomic status
It is much more common for young people who come from a racial or ethnic minority, or for those who have a lower socioeconomic status, to be overweight and to engage in less healthy behaviors and sedentary activities.
FLAC (; Free Lossless Audio Codec) is an audio coding format for lossless compression of digital audio, developed by the Xiph.Org Foundation, and is also the name of the free software project producing the FLAC tools, the reference software package that includes a codec implementation. Digital audio compressed by FLACs algorithm can typically be reduced to between 50 and 70 percent of its original size and decompresses to an identical copy of the original audio data. FLAC is an open format with royalty-free licensing and a reference implementation which is free software. FLAC has support for metadata tagging, album cover art, and fast seeking. History
Development was started in 2000 by Josh Coalson. The bit-stream format was frozen when FLAC entered beta stage with the release of version 0.5 of the reference implementation on 15 January 2001. Version 1.0 was released on 20 July 2001.On 29 January 2003, the Xiph.Org Foundation and the FLAC project announced the incorporation of FLAC under the Xiph.org banner. Xiph.org is home to other free compression formats such as Vorbis, Theora, Speex and Opus.Version 1.3.0 was released on 26 May 2013, at which point development was moved to the Xiph.org git repository.
