Re: GUSI 2 Released (info for Squeak Sockets)
by Bruce ONeel 08 Nov '99

Hi, MacTCP is long gone. Currently one writes modern MacOS networking code in OpenTransport. Soon, one will have to use BSD Sockets for MacOS X. I assume that Carbon (the MacOS compat layer for MacOS X) will support OpenTransport. cheers bruce Henrik Gedenryd <Henrik.Gedenryd(a)lucs.lu.se> wrote: > on 99-11-08 10.17, Craig Latta at Craig.Latta(a)NetJam.ORG wrote: > > > Given > >> MacOS X's roots and some of the proclamations about dumping > >> OpenTransport... > > > > (I assume you meant "dumping MacTCP" there.) > > Apple is abandoning OpenTransport for OS X, sticking with the present > sockets implementation of NeXTStep/OpenStep (BSD?), arguing that it's not > worth fixing something that ain't broken.

Apple is abandoning OpenTransport for OS X, sticking with the present sockets implementation of NeXTStep/OpenStep (BSD?), arguing that it's not worth fixing something that ain't broken. Still, OT is more modern so it's something of a step backward apparently (I'm not an expert on this). Henrik

Pretty Printing
by Rick Zaccone 08 Nov '99

08 Nov '99

I like the browser's capability to pretty print. I have gotten it to work by holding down the shift key and the yellow button on the source pane and then selecting "pretty print". (You can also hold down the shift key and select the menu in the pane's scroll bar.) In the preferences menu is browseWithPrettyPrint. The help balloon says "If true, browsers will automatically format their contents." This doesn't work for me. Is this a bug or am I missing something? It was great to see the members of Squeak Central at the OOPSLA BOF! Rick Zaccone -- zaccone(a)bucknell.edu

Seeking Good Flash Files
by Mark Guzdial 08 Nov '99

08 Nov '99

I'm giving a big Squeak demo next Thursday (to a crowd of Java zealots -- gulp!), and I'm gathering cool resources. I'm having a heckuva time finding good flash files to demo. Most of those that I find on the net are embedded in an HTML file already, and I can't figure out how to download them directly. I was able to get some from downloading Flash, but flash movies of menus and dialog boxes are less than exciting. Could anyone, please,: - either send me a cool Flash movie or two to demo, or - point me to where you can actually DOWNLOAD good flash file demos? I'm particularly eager to show Andreas' cool trick of selecting a sub-element of the Flash movie and pull it out. But again, pulling out a menu item out of the provided Flash demos just isn't much fun...:-) Thank you!

In fact, the #getDocument:... and #postDocument:... methods were reporting back the raw Content-Type header, instead of using the provided #contentType method which will clean it up. Here's a changeset that fixes that. It would indeed ultimately be nice to keep ahold of the content-type parameters somewhere; for now, however, it would be nice if at least the raw content-type is reported correctly. -Lex 'From Squeak2.7alpha of 25 October 1999 [latest update: #1568] on 7 November 1999 at 1:55:50 pm'!
