Re: Newbie Question: How to manage instances?
by Peter Hora 25 May '99

You may want to create a global variable for your album: Smalltalk at: #Album put: Set new. >>> "Peter Smet" <peter.smet(a)flinders.edu.au> 05/25 8:52 am >>> 11 timesRepeat: [ album add: (Track new)]. Should do the trick. -----Original Message----- From: Tim Cuthbertson <timcuth(a)bellsouth.net> To: Squeak Mailing List <squeak(a)cs.uiuc.edu> Date: Tuesday, May 25, 1999 9:50 AM Subject: Newbie Question: How to manage instances? If I create an instance, e.g., aTrack := Track new and then create another instance, again using aTrack := Track new is there any way to get to the first instance, again? If so, how? Suppose I created eleven instances of Track and then wanted to add them to an instance of Album, a subclass of Set. Even if I used eleven different temp variables to hold references to each Track, I am now faced with a similar problem for my instances of Album. If I don't retain the temp variable I used when I created it, I don't understand how to find it, again. I hope this makes sense. Thanks for any help. Tim

oops... Is anyone working on support for floating-point instance variable manipulation *in translated primitives*?
by Craig Latta 25 May '99

Hi-- Apologies if this has been discussed before; I don't recall seeing it. It seems that the latest Squeak doesn't support manipulating floating-point instance variables in translated primitives (e.g., TMethod>>instVarPutExprFor:offset:). Is anyone working on this? I'm doing some work with some algorithms that really want this (apologies also if others are already doing this and I haven't noticed how, but please tell me how... :). I'd prefer to keep doing it all in Squeak and using the translation facilities. thanks, -C -- Craig Latta composer and computer scientist craig.latta(a)netjam.org www.netjam.org latta(a)interval.com Smalltalkers do: [:it | All with: Class, (And love: it)]

Re: Linux Squeak doesn't respond to command line options - Now FLASH BUG
by Peter William Lount 25 May '99

25 May '99

Hi, Thanks. The memory is now being set to what I want. However, the real problem is with the FlashFileStream attempting to create a very very large ByteArray so even "-memory 100m" does not help. I get a "Space is Low" dialog box when opening a file with "Open As Flash" in the file list. The error occurs in primitive 71. in the message "new:" sent to the class "ByteArray" with a parameter of, get this, "2,197,815,309". I guess this is asking too much even when I set the memory very very large! I only have 1 GB of swap space allocated! Obviously the bug is else where in the flash code. The error seems to be occuring in FlashFileStream>>nextTag on the second last line of the method. The temp variable "word" is equal to 831. 831 bitAnd: 16r3F evaluates to 63. This triggers the true block condition which sets length to "2, 197, 815,309". So the nextULong method is returning a bogus length. The same "flash" files open and play on my Intel Laptop but not my Intel Linux box. Could FTP have modified the bytes in the flash files?

(Sorry if you receive this mail twice. I've sent it the past Friday but I beleave it got lost... so I'm sending it again, not from a mail.ru account.)

What I have done is an LPAnalyzer (and the corresponding LPSynthesizer)... the next step would be to implement a DTW algorithm, which is pretty simple I beleave. That could be enough for recognition if isolated words. Luciano.-

Linux Squeak doesn't respond to command line options

Hi, I was trying to adjust the memory setting on the Squeak Linux port and it doesn't seem to respond to the "-memory: 30" command line option. Does anyone have any suggestions? Peter William Lount peter(a)smalltalk.org http://www.smalltalk.org

John Maloney ever-so-kindly sent me one for the Mac. (Thank you, John!) It's at http://guzdial.cc.gatech.edu/st/sqSpeech.sea It makes the voice synthesis work MUCH faster than the original -- and it really works! Great job, Hans-Martin and Luciano!
