Hello all, I've just updated the ftp directory for the minimal MIDI support for Squeak Look in ftp://ftp.create.ucsb.edu/pub/Siren/2.0. This will (hopefully) be included in 2.0, and shoudl serve as a "lowest common denominator" for platform MIDI support. The files, as described in the README, are: MIDI for Squeak 2.0 -- stp(a)create.ucsb.edu -- 1998.05.07 --------Squeak MIDI Support Kernel-Values.st -- Dynamic value framework.

Free, Non-Commercial Version of Popular VisualWorks Development
by Steve Dekorte 06 May '98

06 May '98

Thought this would be of interest to the group. Begin forwarded message: (OBJECTSHARE-INC)(OBJS) ObjectShare Announces New Academic Program; Releases Free, Non-Commercial Version of Popular VisualWorks Development Suite (Business Wire; 05/05/98) Business Editors and High-Tech Writers IRVINE, Calif.--(BUSINESS WIRE)--May 5, 1998--ObjectShare Inc. (Nasdaq: OBJS), the object-oriented solutions provider for network computing, Tuesday announced the ObjectEducation Program, offering a comprehensive, value- added program tailored to facilitate the adoption and education of object- oriented concepts by individuals or within established computer science curricula. In conjunction with this program, ObjectShare is releasing a free, non- commercial version of the company's flagship product, VisualWorks. The ObjectEducation Program also includes proven curricula in objects, and is extended to include tools, courses, and support for both Smalltalk and Java. "It is important for universities to have access to the latest tools and materials to provide a continuing pool of talent in the object-oriented programming market," said Jim Smith, ObjectShare's senior vice president of worldwide sales. "These new programs and products provide universities with exciting new options to create the future of computing." "VisualWorks Non-Commercial and the ObjectEducation program are great news for the academic community, and will make it easy for any teacher to take advantage of the power of Smalltalk," said Dr. Ralph Johnson, coordinator of Project Design Activity, University of Illinois at Urbana-Champagne. "For over a decade, I have been using VisualWorks for both teaching and research. It is ideal for teaching because it makes objects concrete and easy for beginners to visualize. It is full of examples of good design that help students to become good designers, and in research, it lets me build robust systems quickly." The ObjectEducation Program is comprised of three tiers. ObjectScholar, an entry option that includes access to products for teaching/lab use in smaller schools; ObjectAcademy, a full-featured program that adds teaching and research, and Master ObjectAcademy, which adds ObjectShare's proven educational curricula in objects, Smalltalk and Java. VisualWorks Non-Commercial Availability The free VisualWorks Non-Commercial version, for Windows NT, will be made available in May for download from the ObjectShare Web site. This version is a full feature set of the VisualWorks development environment but is restricted license for usage for evaluation, non-commercial, or in-dormitory purposes only.

The stringCompareTest there is comparing the equality of two long, literal strings (which are equal). In most Smalltalk implementations, the compiler recognizes that the literal strings are the same, and uses a single literal for both of them. This means that not only are the strings #=, they are also #==. I suspect that the other "fast" Smalltalk implementations have an early-out test for #== strings in the #= method, whereas Squeak's Collection>>= method does not. One could easily change Squeak's #= method to include this, but I think it would be good to change the benchmark slightly so that actual character comparisons are being performed (by, say, making some of the string comparisons unequal in the last characters). -- tim

stringCompare performance
by Juan Cires Martinez 06 May '98

06 May '98

I've looked at the performance data at http://www.concentric.net/~Dgirle/Smalltalk/Performance.html and it is very strange to see that Squeak has performance that is two orders of magnitude worse than all the other systems for stringCompare. Any idea why?

Re: HotDraw for Squeak ?
by Sam Adams 06 May '98

06 May '98

Stephanie, A version of HotDraw has already been ported to Squeak from the old KSC archives. I'll be posting it soon. BTW, Morphic is alot like HotDraw on steroids(with both positives and negatives), so you might want to check it out as well. Regards, Sam Sam S.

Encouragement, Appreciation and Yet Another Question
by Laurence Rozier 05 May '98

05 May '98

Dan, Alan, Ted et al, Keep up the great work! I've been digging into Squeak for the first time and it feels really great to be back in a Smalltalk environment. Is there a plan to add component/application delivery capabilities beyond fileIn/fileOut or is that something you expect to come from the Squeak community? Is somebody already working on it? Thanks again, -Laurence

As far as component delivery goes, there are a few doing various approaches. I'm one, working on Modules and Interfaces. Unfortunately, it seems that many of us are very busy and are not making too much progress towards release- I know that's my excuse, anyway... les
