What is the practical effect of this that is most concerning? 1. The time taken loading it the first time after installing from Catalog Browser ? 2. The time taken to start it *each* time from World > Chronos Manager, if you open/close it a lot? 3. Distributing Chronos Manager as a packaged application? each time you want to open it Not sure if the following will suit your needs, but in the definition of ChrGUIMorph try moving 'secondsTimerFormCollection' from instanceVariableNames: to classVariableNames: then test by opening/closing the app a few times. After taking a while opening the first time, subsequent openings seem to be faster. > > Also with your solution I lose the ability to update my taskbar icon, by the > way the non optimised code I was using is a direct copy from SystemWindow > class, which means that class should be optimised too. So consider that solution just a problem-isolation step on the way ;). I had another look because I was intrigued that even though you used LRUCache for the /icons/ variable, the ifAbsent: block in #logotinyIcon was being executed anyway. I thought that must be cache size too small and items bumped out, so as a test I replace LRUCache with Dictionary, but the the ifAbsent: block was *still* getting executed (note, this is at steady-state, not startup). So I thought /icons/ must be getting reset. Investigating by putting the following at the top of #initializeIcons... Transcript crShow: thisContext printString , ' <-- ', thisContext sender printString, ' <-- ', thisContext sender sender printString. So now this executes every time I open the World menu. And after ChronosManager is opened, the Transcript scroll rapidly. So everywhere you do something like this... icon: ChrStopwatchSettingsPNG new logotinyIcon where logotinyIcon returns an object, the object created by #new is thrown away. Worse, #new invokes #initialize and hence #initializeIcons wipes out your cache every cycle. Try making /icons/ a class variable and moving methods like logotinyIcon to the class side, so instead you do... icon: ChrStopwatchSettingsPNG logotinyIcon Also move #initializeIcons to class side and add a class side #initialize method to call it. Note that will only be executed when the class is first loaded, so you will probably need to execute it manually in your image. One thing I'm interested in the choice of LRUCache over Dictionary for the cache? Did you find Dictionary was taking too much space? I didn't try implementing the above yet, but I guessing you'll get the performance fix while maintaining the flexibility you want. cheers -ben > Another problem is the scaling of images, really bad with morphic though > Athens must be better. > > Auto completion problems are well knows, sometimes autocompletion does not > show all methods, sometimes autocompletion shows every character you type so > for example ChronosManager open will show > ChronosManager o > ChronosManager op > ChronosManager ope > ChronosManager open > > Sometimes it shows methods that do not even belong to the class forcing me > to use Spotter to find the correct method.

Pharo Sound does not work on Pharo 4

by Dimitris Chloupis

even though it works fine for me in Pharo 5 (with the exception I have to restart the sound player because the primitive fails at times) in Pharo 4 I have no sound and no errors. Just Silence of the Lamps. opened bug report https://pharo.fogbugz.com/f/cases/17402/Pharo-Sound-does-not-work-on-Pharo-4

If there is anything I can do to help you out dont hesitate to ask. I tried to improve auto completion but I have to confess after 30 hours of work I could not figure out how things really worked. So I gave up and went back to coding my own stuff.

Take your time, no rush, Pharo 4 is fine for me. It even has Spotter that I use a lot. More than enough for my needs. I was using Pharo 5 to report back issues and problems but I just cant work with it anymore. So I will sit here and wait here, using a stable version that I know works very well for me without complaining about anything that brakes using a version I should not be using for production code anyway.

Pharo 5 simply does not like me :D On Sat, Jan 16, 2016 at 12:54 PM Dimitris Chloupis <kilon.alios(a)gmail.com> wrote: > > ok if I open a nautilus window and then I save the image , it does not > create this error > > o_O > > crazy stuff > > :D > > On Sat, Jan 16, 2016 at 12:51 PM Dimitris Chloupis <kilon.alios(a)gmail.com> > wrote: > >> [image: Screen Shot 2016-01-16 at 12.47.59.png] >> >> yes even with stable VM is a mess, new problem >> >> I got pharo with this >> >> wget -O- get.pharo.org/alpha+vm | bash >> >> downloads fines, loads my libraries fine with my startup script as soon >> as i try to save the image the above happens >> >> >> >> >> On Sat, Jan 16, 2016 at 12:43 PM Dimitris Chloupis <kilon.alios(a)gmail.com> >> wrote: >> >>> Esteban I also get doSemantics: errors , I have been getting way way >>> back before Spur while trying to use shortcuts.
