Bibi, a Scratch port to recent Squeak

Quoting Frank Shearar <[hidden email]>:

Well, that´s the way the Cuis image is updated. It is the same as the  
"update stream" Squeak used to have.

Yes. Not a problem in my view. To me, the best way to understand the  
behavior at levels #1618 and #1619 is to run the system updated to  
those levels, and use the Smalltalk tools to study it. I.e. I´m a  
classical smalltalker.

BTW, for external packages, we store the full code in a format GitHub  
can understand, version, diff, merge, etc. See, for example,  
https://github.com/bpieber/Cuis-StyledTextEditor/commit/e01cf430657739bfcca197fc9bb1d872e30dd3a2

Criticism is welcome too. I´d really like to have something better for  
the base image, while keeping the nice properties of ChangeSets and  
the update stream. Maybe using DeltaStreams instead of ChangeSets  
would be an option. We´d need to see how to make GitHub ´understand´  
them.

Another option would be to commit, in addition, a condensed Sources  
file each time, to let GitHub diff that?

It's certainly better on the Pi but browser opening is still not as fast as the Scratch image. On the Pi it is as near instant as makes no practical difference.

Not that 450mSec is disastrous by any stretch of the imagination. What does impress me right now is that it doesn't slow down as I open  a dozen or so browsers. In fact
[12 timesRepeat:[BrowserWindow openBrowser]] timeToRun
reports 5200mSec or an average of 430mS.

Same VM, same machine, Squeak4.4-12327
[Browser openBrowser] takes 1900 mS
[12 timesRepeat:[Browser openBrowser]] timeToRun reports 23200

So Cuis is ~4.5 times faster at this test. Good work!

Eagles may soar, but weasels aren't sucked into jet engines.

Hmm, interesting - I thought the Cuis world menu opening seemed a bit slow on the Pi but it's also quite slow enough to be annoying on my iMac 3GHz/Cog combo. That implies something must need improving I'd say :-)

And I look into TheWorldMenu>buildWorldMenu and I weep for wasted cpu cycles that are thrown away carelessly like confetti into a firestorm.
