I used clamwin, the windows version of clamav. That is after I used AVG for a while and went through the same experience. One good thing about using open source application is that they wont ask you to upgrade to some paid version later.
This is great news for people like us. The down side is that publishers may not publish the books, since open access will definitely going to reduce their revenues. It will be interesting to see if MIT can do something like announcing about the literature and hosting it. Which was being done previously by publishers.
The main point of ESR seems to be that it is economically bad for companies to close the source of their product, which is not very true considering apple has very good success rate with both MAC and iPhone. He has not give examples of his "study" about companies which lost because of closing the source of some open source software. If lawyers and corporate bosses are afraid of GPL, let them be. How can you justify removing of GPL just because lawyers and corporate bosses who never contributed anything to free community are afraid of it?
I would agree on DHH, If you really think you can build something cool, why would you wait for two years to learn business aspect of it. As PG says in how to start a startup, "I found that business was neither so hard nor so boring as I feared. There are esoteric areas of business that are quite hard, like tax law or the pricing of derivatives, but you don't need to know about those in a startup. All you need to know about business to run a startup are commonsense things people knew before there were business schools, or even universities" so, why not try out building a startup
IBM has its own business interests to contribute to FOSS, it would be interesting to know what interest FOSS could be for companies like Infosys. Open source contribution requires dedicated interest and a sense of community, which cannot be developed as a temporary option to work on while on bench. The people who might have already worked on FOSS stuff might be able to make some useful contribution, working on new stuff as a temporary option are unlikely to produce useful results
The era of IP, pay per download etc is going to fade away, music companies are better off make money by subscription from user to download all the music they want. Something like
oreilly safari http://my.safaribooksonline.com. This would atleast for now make users stream or download from official sources.
