"Free" and "Open Source" Software: Navigating the Shibboleths

To outsiders, software whose source code is freely distributable is open source software. However, as soon as you become involved with the community that centers around such code, you quickly find that it is also called free software -- and that the two terms are far from synonymous.

Which term you choose to use can quickly associate you with a whole spectrum of political and philosophical beliefs, and can make the difference between receiving cooperation and being ostracized. As a newcomer, you might easily imagine that you have stumbled out of the woods and into the target end of a rifle range, all because of your innocent choice of jargon.

To make matters worse, knowing which of the two phrases to use is difficult, because they are used in several different ways. At the most basic level, they indicate a specific organization and its principles. At another level, the choice of terms may reflect your audience. And, at the most important level, your choice may reflect your ethical imperatives and your vision of the future of computing.

All these meanings blur together, and are heavily dependent on context, so much so that members of the communities can switch meaning in mid-conversation, and sometimes even in mid-sentence. They also carry the baggage of over a decade of co-existence and personal animosities.

Firefox OS media-casting stick strikes Kickstarter gold

The first Firefox OS based media player has arrived on Kickstarter, in the form of a $25 open-spec HDMI stick that supports Chromecast-like content casting. The Matchstick, which has already zoomed past its Kickstarter campaign’s $100,000 funding goal, with 28 days still remaining, was teased back in June by Mozilla developer evangelist Christian Heilmann. The unnamed prototype was billed as an open source HDMI stick that runs Mozilla’s Linux-based Firefox OS and offers casting capabilities. Few details were revealed at the time except that the device used the same DIAL (DIscovery And Launch) media-casting protocol created by Netflix and popularized by Google’s Chromecast. Read more

Open source history, present day, and licensing

Looking at open source softwares particularly, this is a fact that is probably useful to you if you are thinking about business models, many people don't care about it anymore. We talk about FOSS, Free and Open Source Software, but if we really are strict there's a difference between free software and open source software. On the left, I have free software which most typically is GPL software. Software where the license insures freedom. It gives freedoms to you as a user, but it also requires that the freedoms are maintained. On the right-hand side, you have open source software which is open for all, but it also allows you to close it. So here we come back to the famous clause of the GPL license, the reciprocity requirement which says, "If I am open, you need to be open." So software that comes under the GPL license carries with it something that other people call a virus. I call it a blessing because I think it's great if all software becomes open. Read more
