I'd like to announce the availability of an alpha version of Self for Linux at http://www.gliebe.de/self/index.html It consists of the port of the runtime system, the non-inlining compiler and polymorphic inline caches to the x86 platform. It is based on Gordon Cichon's port. Please note that the current version is still alpha, but it allows you to run the Self user interface (ui2) and to get an impression of Self if you have no Sparc or Mac. It requires a lot more testing, so any feedback is welcome.
Have fun and merry Christmas,
