$Permittivity/Dielectric Constant: Do The math - Dator$

522Chapter 24Parting ShotsThe three things we can say with confidence are that with Java, Linux, andOpen Source, the platform and the tools only get better, the price doesn’t goup, and everyone has the chance to play on an level field.We wouldn’t dream of predicting the future, but we’re sure that bothLinux and Java will have a significant place in it.24.2OUR BOOK IS YOURSThis is an Open Content book (as we explained in Preface). You will be ableto take it and do with it what you please. We plan to keep improving the bookonline, and we’d like to invite you all to join in. The authors (who like to referto themselves in the third person) have the book set up on public servers athttp://www.javalinuxbook.com/ and we welcome comments, suggestions,even patch files.Don’t be afraid to participate. Credit of some sort will be given to everyaccepted contribution.24.3CAME THE REVOLUTIONA lot of people write about Free Software and Open Source in terms rangingfrom economic history to political revolutionary rhetoric. One of your presenthumble authors has even written the phrase “economic inevitability” in a weakmoment. And while there is ample room to speculate on the future by lookingat the past, and while there actually are legitimate issues of liberty, rights, andpolitics in the mix, it is always shaky when an argument veers close to tautology(“Free Software is right because it is right”).Some people will actually choose Free Software for political reasons, justas some Americans chose rebellion for political reasons. But the majority ofAmericans in 1776 were not revolutionaries, and the majority of people usingLinux are not either. We have other concerns. In both cases, keeping bread onthe table is a greater concern for most than the revolutionary issue.Read Richard Stallman’s writings if you are interested in the revolution.Read Lawrence Lessig 2 if you are interested in the politics and legal issues.2. A Stanford Law School professor and founder of the Center for Internet and Society, Lessigis the author of three remarkable books: Code and Other Laws of Cyberspace, The Future of Ideas:
24.5 Resources523Most of us, however, will be asking how these technologies can put bread onour table.The key is lifelong learning. And that is where Open has a distinct advantage.You want to know how it works? Look. There is a lot of good code (andsome very bad code) out there, free for the taking, analyzing, and for certainuses. One of the arguments made for closed code is a quality argument. But asprogrammers who have worked on closed systems, we can tell you that we haveseen plenty of bad code out that is closed and proprietary. You just have to lookat news about viruses and worms to know that. The point is that Open Sourceand Free Software are a safer investment. In closed systems there is alwayspressure to “churn” the APIs so that new OS versions and new developmenttools can be sold. There is some of that in Free Software too, but you can watchit as it happens, and if a program is your bread and butter, you can participate.In any revolution, there are the brave and foolhardy rushing to the barricades,banners in hand. But the sensible are keeping their heads down and tryingto figure out how to get through it all. We hope our modest contributionhelps the latter.24.4WHAT YOU STILL DON’T KNOWThis is a book about writing Java applications on Linux systems. We hope we’vegiven you enough to get started, and pointed you to some tools and techniquesthat, while they’ve been around a while, may not all be well known ordocumented.We’ve said it before, but each of our chapters tried to cover in a smallspace what really takes volumes. Our aim has been to give you a flavor, and astart, and a direction.24.5RESOURCESThis book that you are reading is part of the Bruce Perens’ Open Source Series,“a definitive series of Linux and Open Source books” according to the publisherThe Fate of the Commons in a Connected World, and Free Culture: How Big Media Uses Technologyand the Law to Lock Down Culture and Control Creativity.
