I couldn't wait to see :)<o:p></o:p> <o:p> </o:p> I ran out of mean examples :D<o:p></o:p> <o:p> </o:p> One observation though: Sometimes, although rarely and irregularly, this happens:<o:p></o:p> <o:p> </o:p> I run an example (in the Workspace), e.g. this one:<o:p></o:p> <o:p> </o:p> [1/0] fork.<o:p></o:p> 5 seconds asDelay wait.<o:p></o:p> self error: 'error'<o:p></o:p> <o:p> </o:p> and then I move the first debugger window and close it before the 5 second delay expires and when the second debugger opens I get an MNU error concerning drawing - I'm enclosing a snip (if I knew how to file out the debugger's stack contents I'd send it too). And the next time you run the same example it may happen again or may not... Can't figure out any pattern except you have to move the first debugger window before closing it.<o:p></o:p> <o:p> </o:p> --<o:p></o:p> One stupid question: How do you make the image download the latest changes you made at github? I thought this would work: World menu -> changes -> install new updates but it doesn't... Now I think it's maybe not supposed to download from github but just locally from the CoreUpdates folder... Is that so?<o:p></o:p> <o:p> </o:p> What I do now (sorry if it sounds too stupid) is I download a new image which contains the latest changes in the CoreUpdates folder already...<o:p></o:p> <o:p> </o:p> The thing is I'm on Windows and don't do any git stuff or any command line stuff ;) Is there a way for users like me to update easily?<o:p></o:p> <o:p> </o:p> --<o:p></o:p> Well, actually, what would think about situations like this:<o:p></o:p> <o:p> </o:p> [1/0] fork.<o:p></o:p> [ 10000 factorial. Processor yield ] repeat<o:p></o:p> <o:p> </o:p> would you expect, or consider reasonable to expect, the UI to process the 1/0 exception during the long computation?<o:p></o:p> <o:p> </o:p> I'd tend to say no but then when I look at this example:<o:p></o:p> <o:p> </o:p> [1/0] fork.<o:p></o:p> [ 10000 factorial. 5 seconds asDelay wait ] repeat<o:p></o:p> <o:p> </o:p> I'm not so sure... The delay blocks the UI and a thus a new UI is created etc. while in the former case yield just allows other processes of the same priority to run etc… which are implementation details… <o:p></o:p> <o:p> </o:p> And if you run the former example forked:<o:p></o:p> <o:p> </o:p> [[1/0] fork.<o:p></o:p> [ 10000 factorial. Processor yield ] repeat] fork<o:p></o:p> <o:p> </o:p> You won’t be surprised the 1/0 exception is executed immediately after the first yield. Which leads me closer to expecting the 1/0 exception appear after the first yield even in the former example. I believe the computation’s result shouldn’t depend on whether it runs in the UI or not. <o:p></o:p> <o:p> </o:p> I'm curious to know your opinion.<o:p></o:p> <o:p> </o:p> Many thanks,<o:p></o:p> jaromir<o:p></o:p> <o:p> </o:p> <o:p> </o:p> <o:p> </o:p> <o:p> </o:p> -- Jaromír Matas<o:p></o:p> mail@jaromir.net <o:p> </o:p> <div style="border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in"> From: <a href="mailto:JuanVuletich@zoho.com">Juan Vuletich</a> Sent: Thursday, July 14, 2022 19:17 To: <a href="mailto:cuis-dev@lists.cuis.st">Discussion of Cuis Smalltalk</a> Cc: <a href="mailto:JuanVuletich@zoho.com">Juan Vuletich</a>; <a href="mailto:mail@jaromir.net"> Jaromir Matas</a> Subject: Re: [Cuis-dev] FW: FW: Freezing UI - can't interrupt via Alt+.<o:p></o:p> </div> <o:p> </o:p> Hi Jaromir, Just added a few new changes.
