Hi,
P.S. i think i know the answer to question why "computer revolution didn't happened yet", because every time people inventing something new, they implementing it in C.
Can be more of one reason, e.g. ... because people are still thinking in bootstraping... a new genesis... something irrelevant in terms of open systems (ambience), like Smalltalk. Under the point of view of systems where semantics can change, the genesis is only anegdotic. It is more important the sustainability of the system itself (the persistence of the self... when contents change through time), the survival in case of accidents (after sensing damage), and the preservation of identity (been known as the SAME systems after changes). Many syntax can coexists, and it is related with diversity of expression; not with ideals (a mother language/syntax to make the first spell).
The change of semantics though actions "outside" the system itself make us continue writing programs. oops! the Program class is still missing! :-P IMHO, changes in core semantics and the effects of doing the changes in the system should be promoted, because are important evidence to recognize smalltalk as an open system and not as another OO language (the contrary has happened during last years, insisting in the importance of the "code").
Yes, of course, and C compiler is available anywhere!.. then for bootstrapping the image you will just need sources in a text form..
Image as the snapshot of a system, contains representation of objects.. in text or binary; it is only what has been stored from a system in the past. It is as important as a snapshot of a woman. I prefer to invest my time gaining experience with the living woman. People that write good poems (code) are forced to write another, tomorrow.
Ah!.... Another reason for "computer revolution didn't happened yet", can be because people still think in terms of computation, as systems are still made to compute something.
cheers, Ale.

But, Yoshiki is talking about, that you could "generate a growable image file from all text files, or make deep changes to the system without shooting yourself". And this is really awesome and so long waited step!
Well, you do need a C compiler, presumably in the form of an executable binary.

machine code available everywhere, C are not :)
And if you're going to grant special dispensation to an "external tool" implemented in C, why not to an external tool implemented in Smalltalk?
sure, may be eventually this "external tool" could be bootstrapped by Ian's COLA... also just from "all text files", needing in a C compiler on the first stages only.
can anyone tell me, when last time he had to deal with hardware, which having no preinstalled operating system/BIOS up and running, or there only C compiler and no any other languages which can run on it?
