Is it open?

Today I got another one of those InfoWorld articles with one of those sensational titles called "Beware these open source lock-in schemes". I had to take a look. The open-source world has really come a long way. I remember when telling people a product was open-source would be a cause for immediate argument and accusation. Now there are businesses and governments who are looking for open-source as a requirement. As is always the case, people are stepping forward to take advantage of that interest in somewhat nefarious ways.
There has been a lot of information floating around about the "hidden costs of using open source", as though there were no hidden costs to using any technology. It's true. Any piece of open-source software will make demands of you. You will need to understand it. You will need to spend time making it work the way that you want. You will need to make sure that others who use it also know what they need. I have never bought a piece of technology that came with someone who prevented me complicating my life with it through either improper use or making mistakes.
The whole point of working with open-source from my perspective is leaving your options open. Right now I'm using Ubuntu, but it's not my only Linux option. I have run other distributions in the past and may run others in the future, but it's my choice. Linux is at the core of all of them and the software that is important to me runs on all of them. They keep me because they serve my needs, not because I'm too invested to move.
In the article, Simon Phipps mentions the "four freedoms" of open source, which should be protected in any choice that you make. These freedoms are fundamental and important. I'm quoting them here from the GNU philosophy page with my own comments:
So, there you have the four freedoms... the hidden benefits of open-source software. These are the reasons why open-source matters. It's true that these freedoms come with a little bit of effort to make the most use of them. They can introduce a certain level of chaos into your technical life which you will occasionally have to manage... but I'll bet that you do those kinds of things already and call it the "cost of doing business". Think about it.
Things around developerWorks
Tuesday is publishing day on developerWorks, so here are a few items that you might have missed, but shouldn't:
Ian Shields has been doing updates to his series on the Linux certification tests. His latest refurbish is "Plan Linux hard disk layout and partitions". I've worked with Ian behind the scenes at IBM for a while and his shares my perspective on being a repetitive voice in support of Linux and open source in the work place. In any meeting on new things it was always a contest to see which one of us would be the first to ask "will it work on Linux". Ian is the real deal and you can learn a lot from his articles whether you plan to take the LPI test or not.
Over in the Real World Linux community, Himanshu Arora has put up a nice blog entitled "Zsh - The new Linux/Unix shell everyone's talking about". Zsh has actually been around for a while but it's worth learning more about. One of the interesting features of a Linux/UNIX environment is that you have choices for your command-line environment. I normally use BASH, but there are times when another is helpful, especially in scripting. Since you can tell a script which environment it should run you can pick your favorite to type in but have the others whenever you wish.
You should also take a look at the entries in the Real World Open Source communities: "Linux is obsolete - A must read debate between Andrew S. Tanenbaum and Linus Torvalds" and "Songbird - Connecting fans everywhere".
