distributing squeak on a network
by Bill Kerr 24 Jan '08

24 Jan '08

What is a good way to distribute squeak on a network (Windows network at my school) ? >From my understanding there is no option but to give each student their own personal image file but the sources and changes files could be left out. http://billkerr2.blogspot.com/2007/07/image-file-virtual-machine-bytecodes.… If I was going to give students both Bots and Squeak then this would result in quite large student folders, the image files range b/w 15 and 20 MB. But I don't see any alternative. With Bots I get prompts about missing sources and changes files if I try to launch it outside of its folder, but it then goes ahead and loads anyway I'll attach some file folders so people can refer to them in an answer, if necessary: BOTS (file sizes in KB unless otherwise specified) .DS_Store 7 Bots.exe 1053 Bots.ini 1 luth.frm 13 Ready.changes 16747 Ready.image 14841 spider.frm 18 Squeak.ini 1 SqueakV3.sources 14202 ETOYS IMAGE AND PR etoys.image 19609 DemonCastle1.pr 582 Launcher.pr 210 Welcome.pr 385 ExampleEtoys (folder) 6.44 MB SQUEAK 3.8 Squeak.exe 1053 Squeak3.8-6665full.image 17969 Squeak3.8-6665full.changes 13878 SqueakV3.sources 14202 Squeak.ini 1 SqueakFFIPrims.dll 30 windows folder SqueakPluginInstaller.exe 6325 cheers, - Bill -- Bill Kerr http://billkerr2.blogspot.com/

silence trashcan?
by Mark Nelson 13 Dec '07

13 Dec '07

How do I silence the 'camera' sound when items go to the trash bin, while keeping the 'preserve trash' functionality? I thought I had this solved when I found the "TrashCanMorph >> playDeleteSound" message, but this is a 'ping' sound that plays simultaneously along with the 'camera' sound. I successfullly eliminated the 'ping' by commenting it out in "TrashCanMorph >> moveToTrash" but I haven't been able to figure out who's responsible for generating the 'camera' sound. Thanks, --Mark

From John Blue: FYI podcast on Squeak use in commercial setting, Dabble DB, comparison to Ruby...
by john blue 09 Dec '07

09 Dec '07

FYI, Avi Bryant, Smalltalk's Lessons for Ruby, http://itc.conversationsnetwork.org/shows/detail3432.html I found this podcast interesting because it talks about Smalltalk use in a commercial setting and philosophy of software models. This is more of a business focused podcast but may be of interest to those doing development and extensions on Squeak. John Blue What the heck is "innovation" anyway? => InnovationCreation.US Subscribe to RSS feed: http://feeds.feedburner.com/InnovationCreation LinkedIN: http://www.linkedin.com/in/johnblue ==== summary of podcast The speakers of Hindi and Urdu can perfectly understand each other without knowing that they're talking in two different languages. Even though the langauges have different backgrounds and scripts, they sound similar. So is the case with Ruby and Smalltalk. The two languages have much in common and, being older, Smalltalk can provide a blueprint for Ruby. There is an incorrect assumption that because of Ruby's open classes and duck typing it is difficult to make a fast VM for it. Between 1989 to 1991, the Self project was a Smalltalk research initiative aimed at making dynamically typed languages run fast. The team spun off a new startup and the resulting implementation, called Strongtalk, was bought back and adopted by Sun for its Java Virtual Machine (JVM). So that problem has really been solved. Ruby can take a lesson about object persistence from Smalltalk. As William Gibson said, "The future is already here. It is just not evenly distributed." Likewise, the future of Ruby is in Smalltalk as it stands today.
