Local Files
by Richard Eng 23 Oct '07

23 Oct '07

In Seaside/Squeak, if you open a local file, eg, file := FileStream fileNamed: MyData¹. contents := file contentsOfEntireFile. ...the file MyData¹ is found in the same folder as your Seaside app. How do you change the default location to, say, /var/www (Apache¹s DocumentRoot)? Thanks, Richard

Squeak / Gemstone / VisualWorks with Seaside
by itsme213 23 Oct '07

23 Oct '07

VW appears to be quite polished and robust for development work ... Is any developing a Seaside app with VW to deploy on Squeak or Gemstone/S? How easy is it to keep from getting tied up in platform-specifics, and how hard to port? Does it even make sense to consider this path? Thanks

Graphing in Seaside
by Robert Bruce Carleton 21 Oct '07

21 Oct '07

I'm considering moving gnuplot generated 2D graphs to Seaside. Can anyone suggest the kinds of Squeak/Seaside tools that could help me generate graphs in Seaside? We're already using PlotMorph in squeak to do this kind of thing in Squeak and I'd like to move that kind of functionality to the web. Thanks, --Bruce

#with: and #children: is one redundant?
by itsme213 20 Oct '07

20 Oct '07

If I call #with: on a canvas/brush and pass a sub-component, why do I also have to register that sub-component in #children: Would it make sense for the #with: to do the needed registration? Thanks!

Suspending UI Process
by Jimmie Houchin 20 Oct '07

20 Oct '07

Hello, While researching the cpu usage, polling issue. I saw a thread on suspending the UI Process which Avi also mentioned that he does. Is there anyway for an image when starting up in headless mode be started up with UI suspended? Are there other ways for the UI process polling to stop? I did see the Suspend UI in the Screenshot tool. Is there another place in the Seaside UI for suspending the Squeak UI process? It seems that it would be nice to have the option somewhere less heavy than the Screenshot tool. It seems that it would be nice to have a means of starting up with UI suspended. Maybe a preference? I am not exactly sure how that would work in a running saved image, stopping and starting images. Hmm? Any way. Thanks for any information, ideas. Jimmie

MinimalMorphic based web images
by Jimmie Houchin 20 Oct '07

20 Oct '07

I have created some images for the community to try out based on Pavel Křivánek's MinimalMorphic images. For more information and to download the images go to: http://www.cyberhaus.us/squeak/ I am hoping to create as resource friendly an image as possible. Hopefully one that I can get hosted at WebFaction my web host provider. And hopefully other webhosts who allow for long-running processes. Let me know if there are any problems with these images or if you have suggestions for improving them. One thing that I've noticed in these images is that they use the CPU every second or two for something. As I watch the system monitor I can see the CPU use jump very slightly, very regularly. I don't remember if there is a way to stop this or not. Any help with this is greatly appreciated. These images are simply MinimalMorphic images with the software that is described installed. I have notes in the images. Please let me know if there is any preferences or settings that should be changed to help these images be more suitable to the task of web applications. Feedback greatly appreciated. Lets get some great images that can be easily deployed by hosting providers all over the world. Even if they don't even know what Squeak or Seaside is. And some excellent documentation for them to deploy these images. Thanks for any help, wisdom and understanding. Jimmie
