RE: B-Tree package?
by John Clarke 05 Mar '99

A long shot I suppose, but for starters - Kenneth Hall of Dublin, Ireland wrote a shareware version for ST/V Win. I recall it appeared on the Smalltalk Forum several years ago, back when I subscribed to Compuserve. Happy trails and Go Smalltalk! John Clarke

The Next Few Months
by Dan Ingalls 05 Mar '99

05 Mar '99

Folks - Since a while before the release of Version 2.3, I promised to let everyone know what The Squeak Team will be up to for the next few months. With 2.3 out the door, we just spent some time on this, so I think I can give you a pretty good idea. Here's the executive summary... Move Squeak content onto external media and the web Make Squeak more approachable and usable by novices Integrate Balloon into Morphic Take a first stab at 3D in Squeak Release Jitter 2 and work toward native code ----------------- Squeak Pages Complete the ability of Squeak to store any Morphic world on a web page, and for any other Squeak to read that world in, active objects and all. Those active objects will include voice-over and event playback. We will know this project is successful when you can explore a full Squeak demo over the Internet starting from the Squeak Release. We will probably call that Squeak 3.0. Modularity Enable the retraction of most changes at Project (or other) boundaries. This will allow one to run active content on web pages without permanent effect to the base image. It should also provide better protection between multiple developmental project in an image. Surface Language Come up with a more approachable surface language for Squeak. Our only constraint is that any existing Squeak methods can be rendered into or read back from the new form. In addition to syntactic issues, this may include a simpler approach to events and control. Programming Support Merge the functions of inspector and browser for simpler bottom-up programming. Simplify stepping, and enhance the display of program state when debugging. Documentation Provide a self-documenting entry to Squeak with intuitive navigation into areas of major interest. By the time we are done, we would like to have covered the basics of presentation graphics, desktop publishing, internet access, music, 3D, and programming. It's a tall order, but documentation is our strength. One of the sentences in this paragraph is false. Graphics Integrate Balloon fully with Morphic to provide anti-aliased display at any scale or rotation. Make balloon graphics editable both as curves and with the feel of sketching. Develop a layered 3D model that can be rendered reasonably via balloon with no need for special hardware, but that can also take advantage of special hardware or OS functions (via pluggable primitives) when available. Work toward a simple paradigm for building, manipulating and scripting 3D content. Performance Complete Jitter 2T (T for threaded), and get it running on most platforms. Study its behavior, and work toward Jitter 2N (N for guess what). Jitter with native code should keep us happy for the rest of the millenium. [Jitter is really Ian Piumarta's baby, but we work so closely, it seems reasonable to include this as part of the plan] ------------------- This is our plan for the next month or two, maybe more. It's probably a reasonable characterization of what Squeak 3.0 will be like -- more approachable, more web-centered, faster, with better graphics. My target for having most of this in a releasable state is May 1. That said, there is lots of other stuff that we probably won't be able to do. Part of our reason for disseminating this list is to give all of you a chance to reflect on the things we at Central are or are not planning to do. Then, to the extent you are interested or capable, you might organize your activities in a manner that would support or complement this general plan. Onward and upward - Dan (for TST)

Squeak and MySql
by Joerg Brunsmann 05 Mar '99

05 Mar '99

Hi all, MySql (http://www.mysql.org) is an open source SQL database server which runs on all possible platforms. Fortunately - MySql has a socket access interface for client connections - a VisualWorks package exist which uses this interface Although I don't like relational databases I ported this library to Squeak 2.3 (why aren't Squeak sockets streamable ;-) in order to make Squeak even more attractive. Perhaps Swiki providers may want to use it, too. Download the Squeak filein and see some screenshots here: http://www.informatik.fernuni-hagen.de/import/pi3/joerg/squeak/mysql/ Use the Smalltalk front end like this: connSpec := (JdmConnectionSpec new initialize user: 'doe'; password: 'mypass'). connection := JdmConnection on: connSpec. resultSet := statement executeQuery: 'insert into aTable (aField) values (aValue)'. [resultSet next] whileTrue: [value := resultSet valueNamed: 'columnName']. Have fun, Joerg

(It's a while since I built it on PPC, and it's entirely possible that the threading, prefetch and constant caching in the interpreter loop are no longer being properly configured. Looks like my entire weekend might be derailed. ;-) > and my message sends go from ~540000 to ~910000. That's more like it! Ian

They might have to switch to NT. It could be just a rumor... but isn't Apple shipping a BSD-based MacOS soon for server use?

Oops. I replied to Dick last night, but neglected to send the email to the list as well.

One other thing... has anyone had any problems running Squeak with Windowmaker 0.20.x (Intel Linux too). I upgraded to 0.50.2, and everything is fine. For the longest time, I thought it had to do with libraries I've upgraded or kernels I've compiled.

Native widget set ofr X
by Michael Roth 05 Mar '99

05 Mar '99

I had read a rumor about a month ago or so that someone was writing a native widget set for Squeak in Qt or gtk. I haven't been able to track it down though. Is there actually such a thing?

Squeak Publicity in Business Week
by Bruce O'Neel 05 Mar '99

05 Mar '99

Hi, In the March 8 issue of Business Week there is an article titled Disney's Mickey Mensa Club. In the European Edition it's on page 50. In the article Alan Kay and Squeak, among others, are talked a bit about. The relevent quote is: "Today, Kay is shooting for another software breakthrough with Squeak, a computer language designed specifically for lickety-split multimedia applications. Squeak will power Disney's vast Web sites - especially its educatinoal sites, where programs rich in images and sounds will help children learn. 'Disney is a great place to try out new ides because they know so much about kids, and they have th size and resources to put your ideas into practice,' says Kay." Lickety-Split - That's a technical term, right :-) cheers bruce
