Language translator
by Jeroen van Hilst 22 Feb '06

22 Feb '06

Hi all, Im still new to squeak. Ive downloaded 3.8 and 9.7100 images and tried to play with the Natural LanguageTranslator. I cant get it to work because i cant save to a new language ? or im not sure how to do / use it... (It gives some error messages too). Is there is list of already made translations somewhere? Or some more pointers on how to use the Translator? It looks impressive, but i need just a bit more info to get it to work (i guess). Any pointers / suggestions welcome. Thanks in advance. Keep up the good work!

Float>>#asIEEE32BitWord
by Philippe Marschall 22 Feb '06

22 Feb '06

Hi I think Float>>#asIEEE32BitWord is bugged for NaNs. Why? Float nan asIEEE32BitWord printPaddedWith: $0 to: 32 base: 2 yields: '01111111100000000000000000000000' which is excately the same as Float infinity asIEEE32BitWord printPaddedWith: $0 to: 32 base: 2 so basically sign: 0 exponent: 255 mantissa: 0 According to the class comment of Float and Google this is the correct representation of positive inifinity. A NaN would have a non-zero mantissa. I think the bug is: exponent > 254 ifTrue:["Overflow" exponent := 255. mantissa := 0]. this should be: exponent > 254 ifTrue:["Overflow" exponent := 255. self isNaN ifFalse: [ mantissa := 0 ] ]. Does this make any sense? Cheers Philippe

Squeak 3.9 Look/feel
by Vaidotas Didžbalis 22 Feb '06

22 Feb '06

Hello, Just noting few things that impacts general look/feel of Squeak. Resizing windows in 3.9 is slow. Perhaps it is because of redrawing taking place during resizing. Do squeak needs redrawing by default? Changing theme does not work. May be button "Change theme" is to be removed before releasing 3.9 if there is agreement that current look is best. What others think? I started using squeak since version 3.5, so just checked that version now. 2.5 years passed. Version 3.5 image was two times smaller, more responsive, it looked nicer for me (nice/not nice is personal thing but ability to change theme is good thing. -- Vaidotas Didžbalis

Thanks Chris: I am completely blown away with the power of Magma. I've used object databases before but not one as transparent as this. It swallowed my whole radio and spat it out again intact. Really there was only one line of active code that saved the PasteUpMorph on which I built the radio. There is only one tiny thing I can't figure. My connectors come back connected unless I close the morph. Then the next load from the database they are disconnected. Still in place but the ends floating. Do you know of any way to close the morph without this happening? Also if I put in a window it restores without the window. I think I understand this because the window is not the root object. If I could get a reference to the window somehow and commit that I'm sure it would work.

Problems with using Squeak 3.8
by David Grietens 22 Feb '06

22 Feb '06

Hello, I have some problems with the squeak version that I just started to evaluate. When I try to update to the latest version, as squeak offers me when i start it up, "all code update servers seem to be unavailable". Loading something from the package loader (fe Games) produces an error (=can't find EOCD position) Im running squeak 3.8-6665full image on a windows XP machine portable. I was also wondering if the squeak version is still evolving ? Can I expect a new version soon? Finally, I would like to find directions on how to build a GUI with the tool, since I think it is not well documented, or did I miss something?

There is no free space in this set
by William Harford 21 Feb '06

21 Feb '06

I have a well used Seaside image that will give me the error. There is no free space in this set! This occurs in a dictionary that is used to hold cached objects from the database. When this happens usually the dictionary is not to big under 100 items. My solution now is to clear the database cache and garbage collect often. This is not ideal but so far it has kept the image alive. I am not sure what is causing this problem. The memory usage of the image is not outlandish and the set is not that large. Any pointer you all can give me to help track down the problem ? Thanks Will
