I am just after short email exchage between me and Douglas Crockford(owner of http://www.json.org/). As a result of this conversation my Symbian S60 JSON library (http://code.google.com/p/s60-json-library/) is now available from official JSON website. Thanks for those who were suggesting me that!
PS. As you can see, I have added page “Ubuntu tips&tricks”, it will be small page with useful commands, tools, etc. If you have any ideas or suggestions, please write a comment. Ubuntu is operating system on which I work recently so I suppose that this page might grow quite big over time.
