Cmd-h on Mac OS X?
by Yoshiki Ohshima 05 Oct '11

05 Oct '11

I recently started using Mac for Squeak coding. I knew this has been a problem for some time but what can I do to setSearchString: when I pressed Cmd-h? Also, when I run a 3.8-derived image on "Squeak 5.7.4.1" on OS 10.6.7, I get a weird display artifact. Since the VM is for cocoa, I just shouldn't even bother running it and use "Squeak 4.2.5beta1U" instead? -- Yoshiki

The 10th International Conference on Creating, Connecting and Collaborating through Computing (C5 2012) 18-20 January 2012 Playa Vista, CA USA http://www.cm.is.ritsumei.ac.jp/c5-12/ Hosted by the USC Institute for Creative Technologies http://www.ict.usc.edu Computers, networks, and other forms of technology are pervasive in our information-based society. Unfortunately, most users of this technology use it for passive consumption of information and entertainment. To evolve into a true knowledge society it is critical that we transform computer-based human activities to engage users in the active process of creating, connecting, and collaborating together. The C5 conference is for anyone interested in the use of computers as tools to develop and enable user-oriented creation, connection, and collaboration processes. Researchers, developers, educators and users come together at C5 to present new and ongoing work and to discuss future directions for creative computing and multimedia environments. We welcome the submission of theoretical and technical papers, practitioner/experience reports, and papers that bridge the gap between theory and practice or that encourage inter- and cross-disciplinary study. === Keynote Speakers === "Helping Everyone Create with Computing" Dr. Mark Guzdial Georgia Institute of Technology "C2P3: Creating and Controlling Personalisation and Privacy in Pervasive Digital Ecosystems" Dr. Judy Kay University of Sydney === Topics === C5 invites submissions of full papers in (but not limited to) the following areas: - Technology-enhanced human-computer and human-human interaction and collaboration - Virtual worlds and immersive environments - Educational environments for classroom, field work and online/distance learning - New technologies for literature, music and the visual arts - Technologies for collaborative and self-empowered learning - Multimedia authoring environments - Gaming/entertainment platforms, virtual characters, and software infrastructure - Social networks and social networking - Novel programming paradigms and languages for implementors - Scripting or visual paradigms and languages for end-users - Creating and maintaining online communities - Tools for creating/managing online services/environments - Distributed and collaborative working - Social and cultural implications of new technologies Papers should be submitted electronically in PDF format via EasyChair at: https://www.easychair.org/conferences/?conf=c512 Submissions must be written in English (the official language of the conference) and must not exceed eight (8) pages.

Uh oh. Your #asNonFraction addition is fine now, I would have committed that. But now I'll have to wait until someone confirms the changed ceiling code is good.

Fwd: [Pharo-project] usability of Pharo and Squeak
by Michael Haupt 05 Jun '11

05 Jun '11

---------- Forwarded message ---------- From: Andreas Wacknitz <A.Wacknitz(a)gmx.de> Date: 31 May 2011 08:18 Subject: [Pharo-project] usability of Pharo and Squeak To: Pharo-project(a)lists.gforge.inria.fr Hi all, I have convinced a friend to take a closer look at Pharo 1.2.1 and Dolphin Smalltalk. He is an experienced Java developer. After some time he started to complain about Pharo. I was discussing with him and now think that he has some valid points. His biggest complaint is: "Why does Pharo always show windows at sizes and positions I don't want?" I answered him: You could set the standard window size in the class RealEstateAgent and furthermore you can create or change >>initialExtent methods in every class that is involved. But his answer was: Why should I do that? It's the responsibility of an IDE. I don't want to program elementary things of my IDE. Why is there no mechanism that let a user set the sizes and positions of windows? Netbeans and Eclipse are doing that nicely. Why isn't it possible in Pharo? After that discussion I now question my own way of using Pharo and Squeak. I have created some changesets that I used to file in when using a fresh image. But that seems stupid now... His second complaint was that he doesn't like the cluttered windows. While programming he had a lot of open windows and told me that he lost overview. Especially in Pharo he is complaining about minimized windows that are hard to distinguish. He better likes Dolphin with tabbed windows that are common in other IDE's. Regards Andreas

Testing Seaside in Squeak4.3alpha-11321
by Hannes Hirzel 03 Jun '11

03 Jun '11

Hi As Enrico mentioned that Pier does not load anymore in Squeak I did a test if Seaside loads and runs. I could load Seaside into Squeak4.3-11321 (as of today) with the script taken from 'Extending the System' "Seaside 3.0 http://www.seaside.st" (Installer ss project: 'MetacelloRepository') install: 'ConfigurationOfSeaside30'. (Smalltalk at: #ConfigurationOfSeaside30) load. (Smalltalk at: #WAPharoServerAdaptorBrowser) open. I run all the test of the category Seaside-Tests 834 of 834 run and passed However I cannot start an adaptor menu 'Apps' / 'Seaside control panel' add 'Adaptor' , e.g. WAComanceAdaptor clicking on the 'start' button has no effect. The feedback still says 'stopped' Any suggestions how to proceed? Thank you for the answer in advance --Hannes

[BUG] [] storeString goes into a tight infinite loop on a cog vm.
by Jerome Peace 03 Jun '11

03 Jun '11

Hi all, This is a two part question. First is this still a bad bug in cog? I am using a March version of cog (3.9-7 ?). I have tried printing [] storeString in Sq11453 running on cog397 and on an earlier cog. The program goes into a tight infinite loop. It will not respond to a user interrupt and AFAICT the only way out is to kill the cog vm from the system console. I originally found it on an older vm before trying to update to the latest one I have downloaded. Second question is what was I really trying to say? I am collecting time to runs for a bunch of blocks. What I wanted to do was to print each block next to its run time. I.E. from a block get a string which if evaluated would be equivalent to the block. I thought that was what store string was for. But for block it doesn't work. It didn't work in 3.9 though there you could at least interrupt the attempt. printString is no help since it just tells me I have a closure. What particular closure remains a mystery. It seems to me that in many cases storeString fails to do its stated function. Anyway is there a known way to get from the block to a readable description of it? Yours in curiosity and service, --Jerome Peace

smalltalk evolution
by info＠tomsik.cz 02 Jun '11

What's current state of squeak evolution? I do get the idea of squeak as independent-smalltalk, which CAN evolve without being fully compatible with the rest of st world (which is IMHO the only way to deliver better language) I've read few dozens of interesting proposals in here (like prototypes and dropping array literals) And while both being pretty interesting I would really like to see smalltalk with [1 . 2 . 3] asArray syntax instead of ugly and IMHO useless #(1 2 3) Syntax should be further discussed, yes, at least because [1, 2, 3] looks much better, but what's the chance of adopting something like this? What's the chance of saying: "guys, we made mistake, #(1 2 3) have really no advantage over blocks (except of performance), so let's drop it, let's simplify the language, let's make it even easier to learn for newcomers." Is something like this "part of plan"? Or is really the "make a new fork if you consider it useful" the only way to go? Because writing meta-program for transforming existing code shouldn't be so hard. Also "dropping" something could be just part of "changelog", even with appropriate convertor for legacy code. And I doubt that new fork could make it through without massive marketing. Even squeak is poorly known. Please do not take it as offense, ST is one of best languages I've ever encountered, but every language can be even better, and we should try.

Imagine something like a whole website or application (or OS) "folded" into, or represented in, an accordion menu, with a fast keyboard short cut for searching "above" where you're at or "below" where you're at. Something a bit like eMacs but more graphical (eMacs content with CSS?). No documents, no pages, no slides, no "beginning" or "ending", just above or below, folded or unfolded, + context. Folded visual content doesn't have to appear like a bar with a phrase. It could be a button bar, or just a single word or letter or icon. A keyboard shortcut brings your "menu bar" or "toolbar" or "navigation bar" *temporarily to your cursor data entry point,* to keep your locus of attention from moving too much (because you only have one of those) ... rather than leaving what you're doing to go "top of screen" or "bottom of screen" or "left" or "right", thereby risking losing ones mental context and focus. Widgets, windows, or other visual artifacts can be placed side-by-side temporarily for comparison too by a keyboard shortcut or from a search result. This disciplines one to remember and express "what" one wants and "why", rather than dedicating brain cycles to figuring out "where" it's kept.

That's a timely observation for me. I'm trying to lay a better foundation for myself with C. I've felt completely in free fall. At first I thought it was the memory management. But it's this back to the prototype, back to the prototype, back to the prototype... Chris
