Without DejaVu fonts GUI works much better, but it still seems to be very heavy for my machine (for example, scrolling of the "Changes that have been done in 3.9" window gives 100% CPU load).

It might be that I was a bit incorrect in my previous message, and I needed to title it "Squeak CPU speed". But the sad story that I do almost nothing with it, I'm just trying to use it figure out what it is. And I see that GUI responsiveness is too low and the such basic operations as changing a window size or moving it (with fastDragWindowForMorphic disaibled) load CPU upto 100%. And after I've installed DejaVu fonts, I need to wait upto 4 seconds everytime I change size of the SqueakMap Package Loader window. Switching from the Class libraries category to Development tools takes about 8 seconds. Thanks, Aleksandr

displaying a grid of images >Robert Withers reefedjib at yahoo.com >Tue Jan 2 23:04:32 UTC 2007 wrote: >Can anyone demonstrate how I could display a grid of images within a >SystemWindow? <snipped> Hi Robert, Why not put a pasteupmorph in a system window. size the pasteup to be large enough for all the pictures. get a collections of centerpoints (for the images) get a collection of thumbnails of the appropriate size. I would use ImageMorphs or make a subclass to customize behavior. paste the thumbs on the pasteup centered at the grid centers. overide the mouse down/up behaviors and it should rock. doing your own #drawOn: is the long way around. Below is a workspace doit to get an example. In 3.9 there are ThumbnailImageMorphs. If you tell them an extent they will resize the picture to fall with in that extent. The other alternative is to use a SketchMorph. HTH.

Squeak speed under Mac OS X
by Aleksandr Skobelev 02 Jan '07

02 Jan '07

Hello! I'm wondering, is there any reason for Squeak to be so deadly slow on iBook with 1.33 GHz Power PC CPU and 1 GB RAM and load it so much? Is it a feature of the PPC implmentation or Squeak itself? Is there any choice that in near future Squeak performace on PPC will improve? Thanks in advance, Aleksandr Skobelev

Monticell or Changesets?

Hi, Coming from Subversion I'm trying to understand if I should be learning Monticello, Changesets, or both, for version control. Please advise. Regards, Grant

Hi Grant, > Coming from Subversion I'm trying to understand if I should be > learning Monticello, Changesets, or both, for version control. If you read the archive of the squeak-dev mailing-list you find some posts about monticello and some difficulties. I think this is not a problem in the time of first steps in squeak. For my first application with squeak I use Monticello and it is very simple in use and provide all I want. Cheers, Frank

Test Failures and Errors
by J Michael Dean 01 Jan '07

01 Jan '07

Downloaded Squeak 3.9-final-7067 and ran all tests; 2160 tests ran with 2138 passes, 2 "expected failures", 15 failures, and 5 errors. The errors include four float errors dealing with arcCos and arcSin. Of less importance to most of us, I assume! But StringTest also fails, indicating testIndexOf failed, making me worried that I have set something up incorrectly. Tried on different Macintosh (G5 PPC, first run was on Intel based OSX) and got similar results with "virgin" download. Are these test failures known? I was rather surprised to have anything but "green" when I ran these tests.
