SM (was OCompletion in 4.3?)
by Chris Cunnington 06 Mar '12

06 Mar '12

Thanks, those are good ideas. I figure an initial scrape of SqS could stay current with its RSS. A list of URL additions (i.e. LightsOut wants DavidLightsOut added to the URL to produce http://www.squeaksource.com/DavidLightsOut ) would allow a script to drain SqS sharpish. Actually... I just realized... no project on SqS with less than a 1000 downloads need be acknowledged. Hmm, that makes working up a list of URL additions radically simpler. Of 85 pages of projects there is an average of 5 projects +1000 downloads. That's a list of 425 projects to add to SM. Hmmm... maybe I'll just do the initial list by hand. SM needs to be reordered into three levels of visibility: Installer script (one click access on the image GUI) Packages Archive (anything older than 4.1) The user shouldn't know how to do anything but choose from a list and press a button. Kabuntu and other efforts to manage dependencies are both beyond me and a drag. The developer can write an Installer script, which he pastes into a form field on the web site. The image GUI needs to be trashed and remade around three levels of visibility. At the moment levels two and three are mashed together confusingly. And I could add a video on the home page (below the Google search pane) explaining levels of visibility and how to release. I kind of like this idea. I may do it regardless. Chris

Re: [squeak-dev] odd gotcha in workspace code for squeak and pharo

Nice! So you mean block closures saves its context BlockContext and return(^) goes to just sender of the context. If Frank was not right, We couldn't send at:ifAbsent: with second parameter [^self] which exits the sender ' s method would not work. 2012. 3. 4. 오전 2:38에 "Frank Shearar" <frank.shearar(a)gmail.com>님이 작성:

I downloaded 4.3 and tried to follow the instructions in "How to extend the system" workspace for installing OCompletion: (Installer ss project: 'OCompletion') install: 'Ocompletion'. appears to work. (Smalltalk at: #ECToolSet) register. fails with 'Key not found: ECToolSet' Any suggestions much appreciated. Doug

Why can't I post mails to SSL/TLS servers in Squeak?
by 강진오 05 Mar '12

05 Mar '12

When I try to mail out bug report to our mailing list, My Squeak always throw an error: "TelnetProtocolError". I looked out the response, and found this message: 530 5.7.0 Must issue a STARTTLS command first. o2sm129678pbb.45 Start TLS? That means It need TLS to send a mail! It seems that my mail server (pop.gmail.com) uses TLS, but Squeak does not support it. How can I make my squeak mailing service also work on TLS mail servers? P.S. I translated 563 phrases into my language! but... 1503 left... Maybe I could finish it after my Squeak version got out of date. Best Regards, - Jin-oh -

Fork Proposal: Cuis & Killer Apps.
by Overcomer Man 04 Mar '12

04 Mar '12

I suggest a new fork or possibly a new orientation for the next Squeak release: Adopt Cuis as the core image and focus on killer applications to attract new Smalltalk users. Thousands of downloads are recorded on CNet for simple apps like a voice recorder. They could all be using and learning Smalltalk. Same for many other applications. That would help make Smalltalk popular again. Recently I found Squeak / Cuis contains many Sound classes. So I wrote up an email suggesting it to a community college teacher friend who had asked for a sound recorder. Imagine my embarrassment when I found the files Squeak supports doesn't include .mp3. Squeak has so much unfinished half starts at programs, why not adopt Juan's work to flush the unnecessary, then get started on building a serious applications team to build truly useful free code. Another example, Roxio is a million dollar software company making a video recorder app. which is not as good as an ordinary VCR and not supported (they have a staff but try getting any real help). Squeak could be capturing a slice of that market and enticing users to learn Smalltalk! And source code can substitute for most support. Another example, Solid Works is a 3D object drafting program that is simple and gets many thousands of users away from AutoDesk. Can Smalltalk deliver most or all of that function with a FFI to openGL and some programming? Certianly! Finally, the one complaint I've heard on the job about Smalltalk is it's slow. I recently added several thousand classes and find simply clicking on the class in a browser is now slow to respond. When end-users, not programmers, can type at 80 words a minute and more in a C app. or they can be limited to 30 wpm or less in a Smalltalk app. they demand C. The new VM was a good improvement, now try to solve the speed issues in the image. Thanks, Kirk Fraser

Cog VM binaries as per VMMaker.oscog-eem.152/r2538.
by Eliot Miranda 03 Mar '12

Cog VM binaries as per VMMaker.oscog-eem.152/r2538<http://www.mirandabanda.org/files/Cog/VM/VM.r2538/> . Fix tricky context state bug that can cause crashes in the GC. Contextpart>runUntilErrorOrReturnFrom: may pop the last argument. Hence if a frame is married in this state its spouse context won't have its last argument slot initialized. If later the frame is divorced and the arguments are not updated the last argument slot can be left with this uninitialized slot and ... bang. The solution is to update arguments as well as stack contents when divorcing. This is good also because it removes the VM's assumption that method arguments are read-only, and that's only enforced by the Smalltalk bytecode compiler, not by the bytecode. -- best, Eliot
