Towards SqueakCore
by Frank Shearar 01 Apr '13

01 Apr '13

In the interests of revisiting Pavel Krivanek's work, and a long term goal of this community, I thought I'd use the Dependency Browser and dig out interpackage dependencies. By scraping the DependencyBrowser's contents together with a bit of UI scripting I've constructed a dotfile of Trunk (attached). Turning this into a PNG results in an 11MB image! [1] Nodes near the top are nodes that aren't used by many things. For instance, ReleaseBuilder's right at the top because nothing depends on it. One thing to note is that XML-Parser and Nebraska are only used by Universes, and that Universes isn't used by anything else. It occurs to me that we could thus remove these 3 packages from trunk and add the loading of these to ReleaseBuilderFor4dot5 [2], and still end up with a 4.5 that while apparently unchanged, actually has a smaller core. What do you think of trying this out as an experiment? How would we unload these packages? (I should note: I've nothing against these packages. They're just packages that aren't woven into the guts of the image, and are thus easily removable.) frank [1] If you have dot installed, `dot -Tpng -o trunk-deps.dot trunk-deps.png` will do the trick. [2] Installer squeak package: 'trunk'; install: '39Deprecated-ar.19'; install: '311Deprecated-nice.2'; install: 'XML-Parser-ael.35'; install: 'Nebraska-ul.35'; install: 'Universes-nice.45'.

Squeak4.5-12568 available
by Chris Muller 01 Apr '13

01 Apr '13

I noticed we did not have any 4.5 alpha version available for download. A clean update from the 4.4 release to the current 4.5 alpha is now available at http://ftp.squeak.org/4.5alpha. PS -- I accidentally also uploaded .image and .changes but no permissions to delete them. Could someone from box-admins do that or add me to the "updates" group and then I can do it?

Modern and Future Smalltalk
by Dennis Schetinin 01 Apr '13

01 Apr '13

Hello, I'm preparing a report for a small local conference on the "Internet Technologies". I would like to present some current Smalltalk trends in this area. First of all, I'm thinking of Pharo efforts in conjunction web frameworks like Seaside, AIDA/Web, Illiad. Certainly I'll talk about Amber and hopefully there'll be a special report on it. I'll mention GemStone. What else should I talk about? -- Best regards, Dennis Schetinin

Hello Dennis, In terms of current Smalltalk trends related to Internet Technologies, may I suggest our on-going work on "service streaming environments" as exposed here (cf. page 359): http://www.aal-europe.eu/wp-content/uploads/2012/11/Proceedings_AAL_Forum_2… It's Smalltalk implementation has been subject to a publication entitled "Web Pontoon: a method for reflective web applications" and available at: http://dl.acm.org/citation.cfm?id=1942791&dl=ACM&coll=DL A related piece of work, which focuses on a framework for dynamic service orchestration in cyber-physical systems, may be found here: http://osl.cs.uiuc.edu/publications/conf/birthday/MechitovA12.html Which builds upon Smalltalk-mediated joint research as for example reported in: http://osl.cs.uiuc.edu/publications/aitami07.html http://osl.cs.uiuc.edu/publications/ios07.html More on this work may be found at: http://adaptiveobjectmodel.com/writings/ http://www.rezarazavi.com/about/cv/publications/ Best regards, Reza Razavi http://www.linkedin.com/in/razavi > On April 1, 2013 at 5:43 AM Dennis Schetinin <chaetal(a)gmail.com> wrote: > > Hello, > > I'm preparing a report for a small local conference on the "Internet > Technologies".

Jabber: What/where is OnlineIdentity?
by Casey Ransberger 01 Apr '13

01 Apr '13

After loading Jabber-jf.8.mcz into Squeak 4.4. JBCBuddyList open. I get a debugger. I'm missing either a class or a global or a classvar or something. OnlineIdentity isn't here. Does anyone know where I'd find it? Thanks in advance. -- Casey Ransberger
