Trying to build SerialPlugin for IrDA under MPW (MacOS 8.6)
by Hans-Martin Mosner 24 May '12

24 May '12

Hi, I recently got a serial IrDA adapter and wanted to play around with it under Squeak. This adapter has a baudrate switching mechanism which depends on toggling the DTR and RTS lines in the correct sequence. To support this, I wanted to build a new SerialPlugin with an additional primitive. However, the plugin as built with MPW does not seem to be accepted by the VM, which still uses the internal plugin in all cases. I've tried placing the plugin in a 'Plugins' subfolder of the VM's folder, and then directly into the VM folder, without any success. I have considered placing debug outputs in appropriate places in the VM, but building a complete VM with MPW is not easy - I would have to create an MPW makefile for the whole shebang, which is more work than I can invest at the moment. Does any of you Mac aficionados have an idea where the problem could be? I have appended the plugin and corresponding source files in a ZIP file (it's not big) so if you want to try it out you could do it right now :-) BTW, would it make sense to incorporate support for switching serial port parameters of an open port into the standard plugin? Closing and opening a port just to change the baud rate seems a little overkill... Cheers, Hans-Martin

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

C5 2012 Call for Papers
by Ian Piumarta 28 Sep '11

28 Sep '11

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. They should use the IEEE 10-point two-column format, templates for which are available at: http://www.computer.org/portal/web/cscps/home === Proceedings === A preliminary version of the proceedings will be distributed during the conference. The formal version of the proceedings will be published by the Conference Publishing Services (CPS) and sent to authors after the conference. For each accepted paper, at least one of the authors needs to attend the conference and deliver the presentation; otherwise the paper will not be included in the formal proceedings. === Dates === Submission of papers: October 7, 2011 Author notification: November 18, 2011 Camera-ready copy: December 16, 2011 Conference: January 18-20, 2012 http://people.ict.usc.edu/~lane/C5/C5-12-CFP.pdf

[CI] Security
by Casey Ransberger 06 Sep '11

06 Sep '11

A friend of a friend passed along a valid concern today: Hudson/Jenkins can run arbitrary shell commands. People all over the place are running public Hudson servers, so I don't think this is necessarily of *great* concern, I mean we can probably just run it in a chroot jail and call it golden. That said, while I've set up several different CI solutions for internal use by software teams, it was always behind a corporate firewall. This will be my first world-facing adventure with continuous integration. I think this is worth talking about. Does anyone here have any experience to share that we can potentially learn from?

by Jordi Delgado 18 Jul '11

18 Jul '11

Hi, Just a reminder: ESUG 2011 Innovation Technology Awards (http://esug.org/Conferences/2011/InnovationTechnologyAwards) We are proud to announce the 8th Innovation Technology Awards. Have you written innovative Smalltalk? The developers of any Smalltalk-based software can enter by submitting a 3-5min video of their software. Entrants demo their systems in a session at the end of Monday August 22nd 2011, after which the conference attendees vote. (A vote consists in providing a sorted list of 3 preferred pieces of software.) The top 3 teams with the most innovative software will receive, respectively, 500 Euros, 300 Euros and 200 Euros. The results are announced in the Awards ceremony that is held during the social event. Applicants should provide the following information on the conference registration server. Once you have registered your personal info, an "Awards" menu allows submitting your software. You can provide this information when you first register, or login again later and update your details. Info to provide: Name of the software Licence information (free, or shareware, or a commercial) Name of the Smalltalk dialect used Names, Affiliation and Country of developers URL for a video (3-5 min) showing a screencast / demo of the software URL for downloading the software or at least a runnable demo Deadline: 30th of july Any Smalltalker can apply (students, companies, ...). The presented piece of code/software should be written in Smalltalk or directly support Smalltalk (e.g. Smalltalk VM). All Smalltalk dialects are accepted. The applicant should own the copyright/copyleft of presented code or at least be the official representative of the copyright/copyleft owner. The software should be available on-line for evaluation (time-limited evaluation version, demo version, free for non-commercial use ...). Bests, Jordi

Mac VM hanging
by Bob Arning 05 Jul '11

05 Jul '11

Hi, I've been using the all-in-one 4.2 Squeak and can't figure out why the VM is hanging. I have some code that runs fine for about six minutes, but if I wrap it in a MessageTally spyOn: [], then the VM will hang after a while (typically 30 to 90 seconds). CMD-period does not wake it up. According to the activity monitor, cpu remains right around 100% and real memory at around 180 meg. Activity Monitor sampling output attached below. Any suggestions?
