Re: Zippier outliner development environment?
by John Maloney 30 Nov '96

Mario and Tim are both right. On the one hand, caching a moving morph in the most obvious manner prevents you from seeing the morph change while you are holding it. This would make, for example, the core sampler much less useful. On the other hand, many complex morphs, such as outliners, are unlikely to change as they are being dragged. Fortunately, the architecture was set up to allow a cached morph representation to be flushed if the morph actually does change while it is being dragged. This enables the best of both worlds. The trick is that damage reports are passed up the morph hierarchy. If HandMorph is in the chain, it can update any cache it happens to have. Lars had suggested doing this sort of caching but performance to a local X server was fast enough that we didn't think it necessary. The multiuser aspects of Kansas have insignificant costs if you are running with only one user. -- John

When you carry one open outliner over another that's 30 ba-zillion redraws coming down the wire. It's not really bad locally, as other Ultra users have testified. I would take a wild stab and guess that your bottleneck is the speed of your X-server. If we ever do another release, you would find an optional "simple outliners" mode. This is good for introductory programming -- regular outliners have become awfully decorated. (A "simple outliner" has somewhat fewer morphs.) Sorry can't help much! Best of luck, --Randy

Hello, I was just now browsing the new HTML Self tutorial and discovered that an image is not displayed (it must be missing from the directory). Look in the page http://self.sunlabs.com/release/Self-4.0/Tutorial/Language/ObjectsAndSlots/… then try viewing the picture bankui1.gif (http://self.sunlabs.com/release/Self-4.0/Tutorial/Images/Bank/UI/bankui1.gif). It is not there. Douglas

You might get better performance than with ui2, but you'll lose a lot of functionality. Bay

Zippier outliner development environment?
by Cameron Elliott 28 Nov '96

28 Nov '96

Hello, I am trying to do a considerable amount to development work in the self environment, using the Self 4.0 release. But with more than 2-3 large outliners open the interactive performance is bothersome. (I admit my patience is lacking somewhat also) I am using a 143Mhz UltraSparc with 64M ram, although my X server is running on a Win95 system via 10Mbps Ethernet. (Its not the best, but I don't think it's the slowdown here) (Actually, today I just upgraded to 128M ram, so that may help) I have done a small amount of system monitoring via 'top', and the problem doesn't seem to be excessive paging. I suspect that the morphic system combined with Kansas is not as fast as I would really like it to be. If I drag a closed outliner around over an empty portion of the world, I am quite pleased with the redraw speed. But when I start dragging open outliners around over other open outliners, things really slow down. I'm pretty jazzed by the outliner development environment, and don't want to lose that, but I was wondering if any the Self team members had other environments that they used for long periods of programming. (Say maybe minus some of the Kansas functionality) I also tried to bring up the ui1 Snapshot, ie: $ ./Snapshot.ui1 Welcome to the Self... "Self 2" But I wasn't quite sure what method to invoke to bring up an X window. (As you can see, I get the VM prompt, "Self 2", but I don't get an X window as I do with the 4.0 release Snapshot) Anyway, Thanks for your help, Cameron

Running SELF
by khac7047＠sparky.cs.nyu.edu 04 Nov '96

04 Nov '96

Hello! I am running SELF on Spark station which has > 64 M of RAM. The OS is Sun 4.1. The Self is very slow, the respond time some times 10-15 min. The disk is constantly running. I think some thing wrong with the installation. Also when I try to evaluate the expressions from VM prompt, I cant start scheduler with VM# prompt start, and I cand evaluete any expression, exept the simplest (|x. y. z|), (|x. y. z| x: 0. y: 1. z: 2) gives me error. What could be the problem? I would appriciate any help. Araz. khac7047(a)cs.nyu.edu
