To close all the games opened you can evaluate: LOGame allInstances do: [:i | i delete]. I'm currently working on a screencast for the LightsOut exercise in PBE. Should be out in a couple of days.

I'm going through the book too. If your problem is that you can't close the game then here's how... First, get halos around the upper-left cell and close it; it should turn blue. Then get halos around the cell that turned blue (which should be labeled 'LOGame') and then you can close the game.

Re: [Pharo-users] How to detect an inactive image?

by Michael Roberts

I guess you would need a way to sample a set of processes that were executing what you considered activity; and ignore the ones that are not. With some data, e.g assuming they block on semaphore when idle, or terminate when idle, perhaps you can make a decision. I haven't looked, but was imagining some of the profiler framework might help because I thought it did process sampling. cheers, Mike On Sat, Oct 30, 2010 at 11:10 AM, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> wrote: > IF you get some answers I;'m interested to know it because we are thinking about what is a VM API to monitor them. > > >> At the moment I have several projects in parallel.

Another Halo Question (complete newbie)

by James Ashley

How-dee! I'm working my way through PBE (no, I've been too broke lately to buy a copy yet *blush*, but I will) and a few other smalltalk tutorials. I've read the documents about getting halos activated in the first place. I'm on linux, where alt-shift middle-click (I'm still trying to get the button colors down) generally works. In the lights out sample, it doesn't. I can ctrl-shift "left" click, get a giant menu, and select "Add Halo." That puts a halo around the individual cell. If I close it, it disappears and shows a blue background (which I'm starting to suspect is a default for morphics...is that close?). If I jump back through the "Add Halo" hoops on that background, or actually manage to click on the border, I just get what seems to be halos for the desktop (system? background? It's always frustrating to start learning a new system and not know the terminology...then again, that's part of the fun). I've been able to close the morphic by adding a "self owner delete" mouse down handler to the cells, then commenting it out until I need it. But it's more than a little painful. I spent about two hours today googling for variations on "morphics decorated frames", but the results I got suggested that I'm not even in the ballpark. I'm sorry if I missed an FAQ or didn't dig far enough back in the mailing list archives. Thanks in advance, James

How to detect an inactive image?

by Norbert Hartl

At the moment I have several projects in parallel. Nearly all of them are web based. I use a cherokee server on my local machine that starts a squeak image whenever I access a project via web browser. For persistency I use piers image based persistency. But I don't want to have all of the images run all the time. I would like to shutdown images if they aren't accessed for some time. I could do it via seaside but then I don't want an image to shutdown while I'm working on the image and not accessing seaside. What is a good measure of activity inside the image? thanks, Norbert

According to the link that Mariano sent, I was able to display the halos (on Windows) with alt+shift+click.

Yep, that helped. I guess that means that halos are always enabled as I could find no Preference (or Setting) to control it. Would that be considered an 'error' in the book/pdf?
