Open-Source Software info

In the January/February 2015 issue, Hadley Wickham wrote a column called “Impact the world by being useful”. In it, he suggested that “the best way to impact the world as a data scientist or statistician is to be useful,”which, he said, we can do by (among other things) writing code and “working in the open.” He proposed that you should release your code with an open source license.

Evan Eubanks from the website WhoIsHostingThis wrote to share a resource that they have put together about Open-Source Software Licenses:

This guide (see below) shares the most popular open-source licenses currently available, with further reading (guides, tutorials and infographics).

About Open-Source Software Licenses

Open-source software is licensed so that anyone can use, alter, and share it. An open-source license (OSS) is a legal contract that determines the copyright of software. Open-source licenses have many practical uses for business and development. The open-source movement has solved many problems that plagued software developers in the past, particularly through crowdsourcing. Rapid development is much easier when millions of users can help developers test and improve the software. One of the most well-known open-source projects is Linux, a free operating system kernel built on top of the GNU operating system. Linux uses the GPL version 2 license. All open-source licenses are intended to govern how the software will be used. This includes:

Private Use: the freedom to use and change software for non-commercial purposes

Distribution: sharing for commercial or non-commercial use

Linking: linking to free and proprietary sources

Patent Grants: rights to intellectual property granted by the government

Sublicensing: an agreement in which the owner of something allows people to use their software to create new things so long as whatever they create is also distributed under GPL

Trademarks: a symbol or word that represents an organization or product

Open-Source Software vs Free Software

Just because software has an open-source license, does not mean it is free. It may be easy to interpret the term “open-source” to mean “free”. Both of these terms have complex definitions that are constantly changing. While all free software licenses are technically open-source, not all open-source licenses are free. Legal interpretations and enforcement of the terms and conditions contained in any given open-source license will depend on the legal jurisdiction protecting the copyright. It also depends on the country connected to that jurisdiction. The seeds of open-source licensing can be traced to free, copyleft licenses created in the United States during the 1980s. The creation of the Open Source Initiative (OSI) in 1998 has helped shape the landscape of the open-source software licensing today. The resource page lists lots of sources, with helpful definitions of key terms, organizational bodies, and historical landmarks related to open-source licensing.

Welcome to the IMS Bulletin website! We are developing the way we communicate news and information more effectively with members. The print Bulletin is still with us (free with IMS membership), and still available as a PDF to download, but in addition, we are placing some of the news, columns and articles on this blog site, which will allow you the opportunity to interact more. We are always keen to hear from IMS members, and encourage you to write articles and reports that other IMS members would find interesting. Contact the IMS Bulletin at

What is “Open Forum”?

In the Open Forum, any IMS member can propose a topic for discussion. Email your subject and an opening paragraph (to and we'll post it to start off the discussion. Other readers can join in the debate by commenting on the post. Search other Open Forum posts by using the Open Forum category link below. Start a discussion today!
