On what basis do you insinuate that they did not have a good reason - a *very* good reason, in fact - to buy Anamorphic and their HotSpot technology? My team at ParcPlace-Digitalk (the former developers of VisualWorks Smalltalk) reviewed HotSpot extensively before Sun bought it. We would have bought it in a heartbeat had we been able to meet Sun's offer. > clayberg> Were you around when the Anamorphic team was shopping HotSpot > clayberg> around to the highest bidder?

That appears to be exactly what you are doing...or do you routinely "handwave" about things you know nothing about? Go back and read the original comment that started this thread: "Javaites probably know that the Self VM project was where Sun's 'hotspot' technology was developed." and Eric L.'s and my replies about Anamorphic. Sun's revisionist history conveniently leaves out the contribution of the Anamorphic team and the fact that Sun *bought* them and *bought* HotSpot. The Anamorphic team, BTW, went on to become the core of Sun's HotSpot team. > Well, I don't think that I have underestimated anything about > Anamorphic; I haven't (IIRC) emitted any opinion as to whether their > stuff worked or not or was significant or not. It worked amazingly well for Smalltalk and was a very significant achievement at the time. The techniques pioneered by the Self team represented only part of what HotSpot did. The Anamorphic team not only pulled together the earlier Self work but quite a few other ideas that, up until that point, had only been discussed as possibilities in various papers (from OOPSLA, ACM, etc.). No one prior to Anamorphic had ever attempted to pull all of those ideas together. > I have just stated the easily checked _fact_ that the Self research > group did themeselves the "pull them all together and prove that they > worked in concert" act themselves for their adaptive compilation > technology, and it was quite a good act, so whatever the significance of > Anamorphic's stuff is, it's not that it was a singular achievement of > Anamorphic's, contrarily to what is stated here: "Contrarily to what is stated here"?!? No one is disputing that the work done by the Self team was quite significant. What I don't understand is why you seem to want to minimize the work of the Anamorphic team whose work you state you know very little about. > clayberg> [ ... ] Several of the ideas for HotSpot originated with Self (or > clayberg> were well known in the literature), but it took the > clayberg> Anamorphic team to pull them all together and prove that > clayberg> they worked in concert. [ ... ] Which was *exactly* what Anamorphic did in fact do. Sun bought Anamorphic and HotSpot for precisely the reason that it went well beyond the work that was available to them from any other source. Why do you find that so hard to believe? > I know very little about what Anamorphic developed For knowing very little about it, you seem to have a lot to say about it. > so I am prepared to > believe that they did eventually achieve results similar to or perhaps > even better than those of the Self team, and that they were highly > significant; but not uniquely significant, as the Self team themselves > used those ideas and managed to "pull them all together and prove that > they worked in concert", indeed quite easily, glaringly, publically so. The work done by the Self team represented a *subset* of the work done by Anamorphic. There was a lot more to HotSpot than just the ideas poineered by the Self team. Sun wouldn't have shelled out several tens of millions of dollars for it otherwise. If all Sun needed was the Self work, they already had that. Doesn't common sense dictate that they thought they were buying something quite significant and crucial to what they were trying to achieve with Java? > Also, in the case of the Self team I don't have to resort to faith; the > demonstration that their stuff works, and works well, "all together" and > "in concert" is well known, published, and can even be downloaded. Which in no way disminishes the significance of Anamorphics HotSpot work or its signicance to Sun's Java efforts (both technical *and* marketing). > perhaps I should have mentioned this before: I have met Mario > Wolczko long ago (but haven't seen him for a few years) and quite I > liked him and his work Wow. That certainly lends credibility to your arguments. Should all of us list off the various experts and industry luminaries that we have met at one time or another. Hey, I shook Bill Gates hand once. Does that count?
