Readability Metrics

Last update : July 17, 2013

Readability metrics are used to evaluate the ease in which text can be read and understood. Legibility is a measure of how easily individual letters or characters can be distinguished from each other.

Easy reading helps learning and enjoyment. There are different ways to test the readability of texts : text leveling, vocabulary frequency lists, affixes, readability metrics. In 1948, Rudolf Flesch published his Reading Ease formula which became one of the most widely used. In 1975, in a project sponsored by the U.S. Navy, the Reading Ease formula was recalculated to give a grade-level score and is now called the Flesch–Kincaid Grade-Level formula.

Clear, succinct writing designed to ensure the reader understands as quickly and completely as possible is called plain language. Using excess of words is called verbosity. A list of plain English words and phrases which have been recommended in United States guides to writing is available at Wikipedia.

Free Software and Open Source Software

Free software is software that gives you the user the freedom to share, study and modify it. Free software has become the foundation of a learning society where we share our knowledge in a way that others can build upon and enjoy.

GNU logo

The free software movement was started in 1983 by computer scientist Richard M. Stallman, when he launched a project called GNU, which stands for “GNU is Not UNIX”, to provide a replacement for the UNIX operating system. Then in 1985, Stallman started the Free Software Foundation, a nonprofit organization with the mission of advocating and educating on behalf of computer users around the world.

In 1998, a part of the free software community splintered off and began campaigning in the name of open source. Nearly all open source software is free software. The two terms describe almost the same category of software, but they stand for views based on fundamentally different values.

Open source is a development methodology; free software is a social movement.

Read the statement of Richard Stallman “Why Open Source misses the point of Free Software”.

SEO marketing and SERPs

Last update : June 29, 2013
SEO (Search engine optimization) is the process of improving the visibility of a website or a web page in a search engine’s natural search results (natural = un-paid, organic, algorithmic). A SERP (search engine results page) is the listing of results returned by a search engine in response to a keyword query.

For WordPress, the leading content management system for blogs, there are number of performant plugins that make it easy to optimize your posts.

The deliberate manipulation of search engine indexes is called spamdexing. Common spamdexing techniques can be classified into two broad classes : content spam and link spam. See the related post for informations about pagerank, content farms, search quality and black hat SEO.
