Squeak Community Monday - today
by Bert Freudenberg 25 Mar '13

25 Mar '13

Two weeks ago we had lots of fun talking about everything from the VM (several VM hackers stopped by) over OpenQWAQ / Immersive Terf (3D stuff is always fascinating) and tablet UIs (the next big thing is here already) to Metacello and git (with Dale, our cross-dialect hero). But mostly we had fun :) Today we're opening a hangout again for 24 hours so everyone worldwide can get their chance: https://plus.google.com/events/cgrv2ob01fsga5ppbunjdg55fnk Feel free to drop by and say hello! - Bert -

Possible to read in postscript file?
by Open Slate 21 Mar '13

21 Mar '13

I am thinking about converting an application I wrote from tcl/tk to Squeak. The app must allow the user to enter and edit formatted text -- a TextMorph works fine for this. In the tcl/tk version I save each entry to an individual file, marked up with formatting commands I created. The tk text widget handles formatted text, it just doesn't include methods for dumping and restoring the format tags. A Squeak TextMorph can save itself to a postscript file. Can it read one of these files and recreate the marked-up text? On a bigger picture, not sure if I should follow this model or just save everything in the image. Disk space is disk space either way. If the tool is set up in its own project space it is relatively easy to file out, right? And back, say for back-up purposes? Thoughts? -- Gary Dunn Open Slate Project http://openslate.org/

Balloon3D Support
by Joseph D. Kulisics 18 Mar '13

18 Mar '13

Hi, I have been trying to get Balloon3D working on a linux installation of Squeak. I'm using the 4.10.2-2614 VM from the UNIX Squeak site. I am also using the Squeak4.4-12327 updated to 4.4-12333 image. After I install the Balloon3D-1.1.3.mcm package through Monticello from http://www.squeaksource.com/Balloon3D, the package appears to load correctly, but none of the Balloon3D morphs work. The all fail to launch because the B3DScanner class does not exist. I've searched the web for a day, and I can't find any information about the state of the Balloon3D package. Is it still supported? If it's supported, where is the B3DScanner class? Is there another source for the package?

Input and output of morphic text
by Marshall Hampton 14 Mar '13

14 Mar '13

Hi, I am new to Squeak and Smalltalk. After reading a few tutorials I am very intrigued and impressed. Brief background for me: I am a mathematician, I am fairly skilled in Python, and I have worked at to varying degrees with C, C++, Java, Pascal, Basic, Fortran, Javascript, Ruby, R, and Mathematica. I am homeschooling my daughter, who is 9. She is quite proficient at Scratch. A week ago I decided to give her a very brief tour of other programming languages by having her write a "Hello Pythagoras" program in each language. This program should print "Hello Pythagoras" somehow, and then ask the user for two inputs (call them A and B). It should then print sqrt(a^2 + b^2). For her third language she chose Squeak, since she knew that Scratch was written in it. I would like to have her write the "Hello Pythagoras" program using Morphic objects, in a visually appealing way. So far I have had some trouble finding a tutorial that covers relevant information. I am sure I can figure this out by poking around long enough but if anyone has a pointer to documentation that might help, or a similar example, that would be great and much appreciated. Thanks very much, Marshall Hampton

Thanks for the fantastic ideas.

I knew I was going to be overwhelmed and blown away when I asked the community for suggestions. I'm at the point where I'm still reading ideas people wrote to share with me, and I have a few favorites that I'm investigating, but I'm gonna have to close the flood gates! Before my brain explodes, SPLAT! FWIW, some of the best ideas came off list from people who's names I didn't know. I'd like to give extra thanks to these folks; it's been great to meet you and hear your wonderful thoughts. I'd love to see this set post on the list(s) more. Also: sorry about spamming the list with the thread. Hopefully I can make it worth whatever bandwidth inconvenience I may have caused. Onward and such! (Up.) Casey -- Casey Ransberger

RE: I need an idea. I know you have some. Give. (Casey Ransberger)

It always bothered me, and still does that there isn't a Table object. Most of my data has more than one key and more than one data items, just like a table in a spreadsheet, or a table in SQL. I think all of us are spending our time packing things into Arrays of Arrays or Dictionaries of Dictionaries when the most simple structure of a Table is what we need. Sincerely, Joe.

I need an idea. I know you have some. Give.

Hello Squeakers! My job search is turning up dead ends, hurry up and wait, and unfathomably boring prospects. Screw all that! I want to do something cool. I'm thinking about doing a KickStarter, but almost all of my ideas are either a) stuff no one else wants which only I could possibly think would be cool, or b) overly ambitious. The words Andreas used to describe my last idea: "a bit grandiose." Gift for understatement at times. So I'm looking for something which could be completed by one or two geeks in six months to a year, which people actually want, to be implemented (at least in part) using Squeak, and to be released at the end under the MIT license. I've floored my expenses, so I can make my own labor (relatively, for a guy living in Seattle) very cheap. By floored, I mean the room I sleep in isn't even tall enough to stand up in -- I do not presently meet the definition of a free-range chicken -- and I've disconnected my cellular service. I want to be an efficient engine for getting things that matter to me and other people done, rather than go on being some tool used to ship lucrative enterprise crapware. So here's the $x question: what do you want me to do? I have a Raspberry Pi on order, so bonus points if you can work that in somehow. The person with the best (realistic) idea will be credited for it. Inspire me! And thanks for reading all the way down to the bottom of this message. Casey

Re: Beginners Digest, Vol 83, Issue 1

Casey, I have posted several project ideas for things people want. Your asking for money makes me focus on things I personally want. My main tech project is to build a robot. I need a Cuis version of the Parallax Propeller Serial Terminal so I can write Smalltalk to control my robot. The current software which is executable only is available here: http://www.parallax.com/ProductInfo/Microcontrollers/PropellerGeneralInform… I don't know if the Linux version has source code to help. For now I need it to run on Windows. A complete function duplication is the first step. What is your bid? Please consider I am also "floored" living in a 1987 RV, no cell, neighbor providing internet. The next step will add a graphics display of the numbers sent and received representing actuator positions and commands. Then possibly a video display of what the robot sees. By then I hope to have a joystick or other control to interface. All this can be published on the Parallax site, Squeak site, or Sourceforge with the MIT license.
