Hi,
I have been thinking about doing some implementation work and writing a self like system where self is the embedded language. I am curious to what extent the ideas in self are patented or in the public domain (especially w.r.t. various optimization techniques described in the literature). Is it feasible to undertake such a project and release it under an OSS licence?
Thanks in advance,
Carter.
Hi Carter,
I'm not sure that you can ever be 100% safe from patents in the modern world...
I can say that it is feasible to create a project with Self's optimisation techniques and release it under a OSS licence because that is precisely what Self is! As well, a number of OSS and commercial virtual machines have incorporated elements from Self's compilation strategies over the years, including Google's V8, Strongtalk and the now open source Java VM.
(This of course isn't legal advice - if you are doing something commercially that might attract the attention of patent trolls then consult a good patent attorney twice a day before meals and get plenty of healthy outdoors exercise. But that advice applies to everything, not just Self :)
Are you thinking of embedding the Self VM itself, or writing a new VM from scratch for a Self-like language?
Cheers,
Russell

Thanks for the reply. I am currently thinking of implementing my own "runtime" system which uses self as the programming language of choice to interface with the system. I suspect just embedding the current VM given my requirements may not work that well.
One follow up question (if you don't mind)- is there a changelog detailing the changes between Self 4.1 (described by the pdf) and Self 4.4? How substantial are these changes?
Thanks again,
Carter.

Hi Carter,
Changelog is at http://selflanguage.org/documentation/changes/detailed/index.html
Doesn't include the latest round of changes yet, which are primarily a new set of primitives for the mac gui and the linux port.
Cheers, Russell
