Re: Squeak 3.8 with big fonts is terribly slow

Measuring 10Browsers, on Windows, going from default fonts to 17 point 
comic I got a ~37% slowdown on 3.8 and 3.9a-6681, and a 57% slowdown on 3.7.

I couldn't find any behavior as bad as what you saw. I did find a few 
bottlenecks that could be easily fixed and got scrolling about 60% 
faster, and brought the 10browser slowdown to about 26%.

Try out these changes and see if they help; if they are useful I'll 
submit them for 3.9.

Re: [ANN] new version of services available for preview

This is a funny thing about these subjective things like what the event 
bindings should be, and alternative looks.

On the one hand, these things are intrusive, and people notice them, so 
there's lots of feedback and argument. On the other hand, they're 
fragile, so they don't get very well maintained outside the image. On 
the third hand, since we are eventually incorporating various changes by 
different people from different periods, we end up having this weird 
collage of things that don't really quite fit together.

When, oh when, will we have people working on the infrastructure to make 
all these themable, easily definable by a single UI oriented person, and 
so forth with half the enthusiasm that people have for yet another tweak...

I will note that services really is exactly such a thing, but the 
infrastructure aspects (we could define keymapping from a UI, instead of 
hardcoding them! you could choose your own, and let no one ever change 
it!) get completely ignored in favor of the "triple-click vs. three-key 
sequence" arguments. Now this is just my opinion, but I say Blech.

Complex functions -- hacking "Float"

I'm looking at Smalltalk for some control systems work, for which  
Complex is essential (plus plenty of other stuff).
I just sent in arcSin etc for Complex, which is probably  
uncontroversial. What I plan to do next, though, is probably
easy to get wrong. For my use, anyway, Float needs to work nicely  
with Complex, and in particular lots of functions
that return FloatingPointException and such at the moment should  
return Complex.

The obvious example is "-1 sqrt", which I plan to have return "1 i",  
but most of the mathematical functions will change.
I propose only to touch the cases that currently return errors.

Is there any obvious reason not to do this? I assume that programs  
aren't being written to rely on the error returns,
for example.

Re: [ANN] new version of services available for preview

Hi Daniel

I agree. This is why keymapping will be an important package in the  
future.
I always found strange that there was only one shortcut table shared  
by all the system objects.
This is also why services are important.

Squeak in Japanese

Hello,

I will make a conference tour in Taiwan and I would like to show Squeak
running with Asian language, I know there are good achievement in
Japanese, so I would like to add to my 3.8 image (a standard one) the
necessary components (I guess font and translation file) to get it in
Japanese.

What do I need to do ?
