Re: Return key not working in GCC Win32 VM

It's very cumbersome to >cut/paste CRs... Ah, and I thought it was only me. Yes, I'm seeing this also, with images going back to 2.7. Other interesting problems have kept me from investigating it yet. Cheers, Helge P.S. I recall an old folklore tale, ever wondered if it was true: When (IIRC) Alan's Alto keyboard was broken, it was sent off to repair for a week, and he continued Smalltalking for the entire week by composing stuff from existing bits. Can the old hats confirm/deny?

RE: [ENH] SelectionMorph (Alignment)

Is your Visio replacement still under development? I'm interested in it; I would like to build a simulation tool based on DFD look-a-like diagrams. Perhaps you can share your work with the community. Jan -----Oorspronkelijk bericht----- Van: Brett Taylor [mailto:btaylor@quiknet.com] Verzonden: donderdag 2 november 2000 20:41 Aan: Squeak Onderwerp: [ENH] SelectionMorph (Alignment) This adds the ability to align morphs vertically and horizontally on a playfield. I added this to support my use of Squeak as a replacement for the Visio drawing tool. This is made possible by the addition of Ned Konz's ConnectionMorph. Tested in 2.9alpha2876 Brett Taylor

Hi, Sorry, sent too fast. Two other bits of useful info: - Website address is www.shockfish.com. - This is in Lausanne Switzerland. The ad in Le Temps (www.letemps.ch) was in English so the would be happy with those who don't speak French well. cheers bruce Bruce ONeel <beoneel(a)mindspring.com> wrote: > Hi, > This cries out for a Squeak implimentation.

Do you have a reference to this patent (I wasn't aware of any patent). >At first blush, and perhaps you can fill in more information about this for >me, it would appear that the current Squeak recognizer would violate that >patent. Not possible. The current one was derived very directly from the original GRAIL recognizer at RAND done by Gabe Groner in 1965 (and written up in a RAND report in 1966). Sponsored by ARPA and free to all (as it should be). It was the original and truly great single stroke recognizer. I have a great movie of it from the late sixties. Nathanial started with the current Squeak recognizer, but quickly took a much different and more flexible approach to the matching process. The PARC Smalltalk recognizer has a line that runs pretty directly from the original Ken Ledeen recognizer at Harvard (a student of Ivan's, he did this recognizer in a very clever way because the PDP-1 at Harvard was a much weaker computer than the RAND 360/40). This recognizer algorithm is given in full in an appendix to Newman & Sproull (edition 1). John Shoch adapted this twice for Smalltalk-72. I adapted it for Smalltalk-76. Vickie Parrish did a later version in LRG. Etc. It is likely that any Xerox patents for a recognizer came later than this, since we had the only one when I was there that I'm aware of, and ours was not patented while I was there (nor should it have been). >Palm won the case only because of some very technical, but >apparently significant enough, differences and those are in turn covered by >_their_ patent for Grafitti. Patents are granted willy nilly these days. The patent office long ago wimped out on trying to vet patents and have left matters up to the courts (a terrible situation that gives rise to an infinity of useless and usually meaningless disputes). This is why there are a number of companies in Silicon Valley that do nothing but demo prior art on old machines. > >On a related topic, we have a Squeak implementation of Ken Perlin's >QuikWriting system, but are unable to use or distribute it because of its >patent, currently held by NYU.

(I'm personally not a big fan of QuikWriting, but it would be fun to have in Squeak.) Cheers, Alan

MPEG (libmpeg3 code) relicense
by John M McIntosh 04 Nov '00

Ok, well I was going to wait until I had the headers etc changed but since the windows DLL is out I'm please to announce that we've re-licenced the libMPEG3 code with the following licence: I hereby grant and jointly license my software, ________libMPEG3_________, under the terms of either the GNU Lesser General Public License, also known as the "LGPL", or the Squeak License set forth below, at the option of the licensee or any sublicensees.

I'm going to change the headers to reflect the new licensing, where to get a copy of the re-license letter, and integrate the Windows changes etc, this should take place in a few days and I'll let everyone know once it's done so you all can retrieve the correctly licensed source and DLL's PS I've also a few changes to make to the smalltalk code in the area of player controls... -- -- =========================================================================== John M.

[ENH] Point hash
by Andres Valloud 04 Nov '00

04 Nov '00

Hi. Here is an improved version of Poin>>hash. From the preamble: > "Change Set: PointHash > Date: 3 November 2000 > Author: Andres Valloud > > Reimplements Point>>hash to use hashMultiply. > > Soon, we should implement hashMultiply as a primitive and let the system fly!" This changesets needs the method Set>>quickRehashAllSets, which should be in the image (I guess). Andres.
