A recent article caught my eye and turned it a nice shade of red. It discussed the -- hardly new -- idea that the future of software usage must involve a mixture of free and proprietary products -- something the writer refers to as "mixed source". The piece was entitled "Mixed source - the best of both worlds" which may give you a clue as to where I disagree with it.
The article was an opinion piece by Steve Harris, senior director for open source products at Novell in issue 78 of Linux User & Developer magazine. Sadly it's not yet available on-line and I don't honestly know if it will be. If it is I'll post a comment with a link here so you can read it for yourself.
