Re: Squeak on Linux


Hi,
Thank you all for your help. I've managed to get it installed. I basically
made three mistakes:

- I used 'desktop' zip/tar/gz programs to explode the archive - this caused
the to set the permissions on the underlying files/directories to be wrong
in some cases
- I associated the image file with the wrong Squeak executable; instead of
the installed one I used the one from the Archive
- I tried to install the lib i686-pc-linux-gnuoldld as that's what the
system told me. This should have been i686-pc-linux-gnu

I must say, it now runs like a dream on Puppy Linux. The installation on
Mandrake seems overload on the hardware so I'm now trying xubuntu.

Can I suggest to amend the Unix documentation to include the above for
Linux/Unix newbies like myself?

Again, thanks for all your help

Ted

Re: JNIPort

the moose guys will certainly start developing in Squeak and been able  
to talk with eclipse is really important.
So let us know.

Re: Sapphire is a good news

We accept help :)
There are plenty of space to clean and rejuvenate or simply invent.

Re: Undoable environment ?

You can also have a look at the Iterator DP in the Smalltalk companion  
they have  an hisotrystream to manipulate commands
and do undo.

Squeak 3.9 alpha image wanted

Hello,

can anyone tell me were to find the earliest available 3.9 alpha image?

I want to identify the cause of the slowdown of browsers when you have
many of them opened.

  http://article.gmane.org/gmane.comp.lang.smalltalk.squeak.general/108359

I am using the benchmark from Andreas. So far I see the problem in the
current squeak-dev 3.9.1, Squeak3.9b-7029.image. Browser speed is OK
in Squeak3.8-6665.image (Squeak3.8-6665-basic.zip).

Cheers

Matthias

PS: Benchmark results on my machine:
"Run this several times, do not close browser windows."
win := Browser openBrowser topView.
win extent: 600 <at> 350.
br := win model.
br setClassOrganizer.
br systemCategoryListIndex: 2.
World doOneCycle.

Transcript cr; show: [1 to: 10 do:[:i|
       br classListIndex: i.
       World doOneCycle.
 ]] timeToRun.

Re: Squeak 3.9 alpha image wanted

Even a simple

	MessageTally spyOn: [Transcript cr; show:'hello'].

exhibits a factor 2x slowdown between 3.8 and 3.10

And the main difference lies in the drawing of the container, not the 
contents as you can test it:

Smalltalk garbageCollect.
theTranscriptWindow := SystemWindow allInstances detect: [:e | e label = 
'Transcript']. "(I know, bad code, but cannot remember correct API)"

Time millisecondsToRun: [theTranscriptWindow drawDropShadowOn: World 
canvas].
	=> 4 36
Time millisecondsToRun: [World canvas drawMorph: theTranscriptWindow ].
	=> 4 21
Time millisecondsToRun: [theTranscriptWindow drawSubmorphsOn: World canvas].
	=> 18 11

Scores are given in 3.8 and 3.9/3.10 (where they are dependent on 
theTranscriptWindow bounds extent).
Notice the transparency and background gradient in 3.9/3.10...

Don't know how this connects to number of opened Browsers seriously

[ANN] MCConflicless

Hi all,

	I've published this package in http://www.squeaksource.com/mc 

Definition: Allows to selectively merge changes which are without conflicts
among different version of one package.

Applicability: To be able to reject non conflictive and poor quality code. An
example can be a tired developer commiting bad parts of code due to distraction
or exhaustion and mergers are able to reject that parts preserving the quality
of the branch and that developer's health and best success :)

Note: if you install UI Enhancements from Gary, this package will also make you
able to use diff tools merger choosing, for each change, which is the winner and
the looser of the merge (which, IMHO, is the most useful tool for that this
days).

What are the implications on the ancestry information? What about
repeated-selective merges?
