The Scratch serial interface works through the USB port via USB to Serail converter to go to the old standard 9 pin Serial if that what you want. The driver download for Mac OS X <http://www.prolific.com.tw/support/files/%5CIO%20Cable%5CPL-2303%5CDrivers%…> says it requires "Device using PL-2303H/X". PL-2303HX (Chip Rev D) USB to Serial Bridge Controller <http://www.prolific.com.tw/eng/downloads.asp?ID=23> But if you need to hook up to a USB device that does not show up as a serial device in /dev, or does not use the PL-2303 to convert from USB to 9 pin serial, it seems to me you are in some difficulty. Maybe also a good starting point tho.

How to compile FreeType Plugin (FT2Plugin)?
by Takashi Yamamiya 21 Mar '08

21 Mar '08

Hello, I have a problem to build FT2Plugin by VMMaker. Does someone could give me a hint? In FT2Plugin>>primitiveCopyToExternalMemory: ... rcvr := self primitive: 'primitiveCopyToExternalMemory' parameters: #(ByteArray) receiver: #FreeTypeExternalMemory. ... When I generated FT2Plugin, SmartSyntaxPluginTMethod complains that FreeTypeExternalMemory should be a Behavior, but there is no class with such name. I used Freetype-Base-be.70 and Freetype-Plugin-JMM.53 at http://source.impara.de/freetype/. The image was based on Squeak3.9alpha #7021 and the OS was Fedora Core 7. I want to use FreeType for OLPC eToys, and I tested it with FreeType Plus 0.4 and FreeType Plus (plugins installer) 0.13 on SqueakMap. It worked pretty well with small change. That's a great job! But I want to keep all vm source code at one place, so I need to build the plugin by myself. Any help is appreciated. Cheers, - Takashi

Squeak Hierarchical Browser?
by Trygve Reenskaug 21 Mar '08

21 Mar '08

Does anybody know of a Squeak hierarchical browser similar to the ones we find in Windows Explorer, NetBeans and many other places. You have a list of nodes. Click one, and it expands, showing its subnodes. Click it again, and it collapses.

Squeak board meeting minutes, 2008-03-19
by Craig Latta 21 Mar '08

21 Mar '08

Hi-- The Squeak board meets on first and third Wednesdays. At the 2008-03-19 meeting, all board members were present (Dan Ingalls, Craig Latta, Bert Freudenberg, Yoshiki Ohshima, Tim Rowledge, Randal Schwartz, Igor Stasenko). Andrew Black, from the previous board, also attended to hand off old business. Thanks to Andrew, Cees de Groot and Stéphane Ducasse for their service on the previous board! Andrew said that he had Squeak badges remaining, and that he would send some back to Tim, and hand off the rest to Randal in person at some point. Thanks to everyone who has been discussing the squeak.org website. It is our unanimous recommendation that Janko lead the web team, and continue coordinating work on the Squeak website. Our main concerns are that the site be "search engine friendly", and that content updates happen in a timely fashion. While we don't think a change in the site's infrastructure is strictly necessary to address those concerns, we like what Janko has done so far and appreciate the energy he has brought to the task. We exhausted the hour we had for the meeting before addressing Brian Rice's request (about updating the content at the current site). Sorry about that, Brian. Speaking for myself, it looks like Janko's demo is far enough along that Brian might be able to make the updates there. I'm hoping that he and Janko can come to some agreement about this. As the Teams coordinator, I'm happy to help further that discussion. Finally, the board agrees that the web team list is a better place than squeak-dev to discuss the website. If you care about the website, please join and participate[1]! thanks! -C [1] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/webteam -- Craig Latta improvisational musical informaticist www.netjam.org Smalltalkers do: [:it | All with: Class, (And love: it)]

Re: [Newbies] Seaside vs. AIDA
by Rob Rothwell 21 Mar '08

21 Mar '08

Leon, I am both "new" to Smalltalk (been staring at an "empty" browser for a couple of years!) and to Aida, but believed in the ability of Smalltalk to be the right tool for the job to build some tools I need in a Healthcare Environment. I didn't know which to choose either! As a new Smalltalker, I couldn't understand Seaside to the point where I could figure out how things worked and how to do something with it WITHOUT following a tutorial line by line--and yet it felt very "meta-capable." Just beyond me! However, I have no doubt it can do great things. It just feels very theory-based for a newcomer. I felt like I HAD to understand web programming and HTML just to make it work. Aida, I got. Very down to earth. Almost like "PRINT 'Hello'". It seems to abstract the web aspect a little better (for me). While I still have to ask for help, I'm usually "almost there" on my own. It just seems to "make sense" to me. I think I have actually been able to turn a major Smalltalk learning curve because of Aida. I like the strong Model-View relationship it forces you to use, and, indeed, supports what I am calling the "Model-View-Design" triad whereby (if I actually knew more CSS) it is relatively straightforward to restyle your site separate from your view and from your model. (I am SURE Seaside does this too...again...how?!). I'm not trying to make a pitch either way, I just followed the "keep it simple" motto and went with what I could understand, and yet I still worry about my choice occasionally because of the very large Seaside bandwagon--Will there be more examples available? Will I be able to get more help with Seaside? All that stuff. I guess what I'm trying to say is that even if the objective facts pointed out that Seaside was better, smarter, faster...it still wouldn't work for ME right now because I can't make it work. Aida could be that way for you--I would go with whichever fits YOU better (or your team), because they both seem like mature products that will be around for a while.

Available from John McIntosh at <http://www.smalltalkconsulting.com/squeak.html>, <ftp://ftp.smalltalkconsulting.com/experimental/EnhancedSerialPorts-JMM.11.c…>, here's a copy on Mantis with some fix-ups for Squeak 3.10Dev, <EnhancedSerialPorts-JMM.11wSmalltalkFixesFor3.10-kgb.cs-M6966>, downloadable at <http://bugs.squeak.org/view.php?id=6966> Otherwise the JoyStickPlugin <http://hitoro.net/squeak/2004/11/23/joystick-support-for-mac-os-x/>, available on the Squeak svn source repository <http://www.squeakvm.org/cgi-bin/viewcvs.cgi/>, or the HIDPlugin <http://www.squeaksource.com/HID.html>, HID-dd.4.mcz appear to be closest to what is needed to start with, if the device is visible to USB as an HID device. The HIDPlugin is able to pick up the device information and can read some items for a mouse or tablet, but does not have the interface bits required to actually transfer bytes bi-directionally serially. The Stick plugin may be of interest for Windows: <http://www.lazarevic.de/stick.html> The www site says: The Stick Plugin for the Squeak VM aims at providing better support for using real Joysticks (or Gamepads) from within Squeak than there is currently through the old JoystickTabletPlugin. I chose to try to extend the HIDPlugin for serial bi-directional byte transfer which I am only part way through. I am working on that at the moment and can supply an in process Xcode project for compiling the HIDPlugin as an external plugin to help get you started. Lukas has some example Serial code for USB devices that show themselves in the /dev directory. His code is for interface to the Lego Mindstorms Nxt. <http://source.lukas-renggli.ch/nxt.html>.
