accelerated OpenGL on linux/nvidia (crash)
by Radek Doulik 08 Feb '04

08 Feb '04

Hi, I am experiencing crashes with Ballon3D. When I enable hardware acceleration, sooner or later squeak crashes. I found some comments on swiki (http://minnow.cc.gatech.edu/squeak/2904) about using older NVidia drivers, but this semi-solution doesn't work for me as my card is not supported by old driver. The behavior explained there seems to be similar to my case. I tried various VM and image versions, including 3.4 packaged by rpm available on http://www-sor.inria.fr/~piumarta/squeak/ without success. It still crashes. Other OpenGL applications run without problem so it seems to be squeak bug/problem so far. Any idea what could be wrong and/or how to fix it?

How to start Squeak under WinXP from image on network?
by Ned Konz 05 Feb '04

05 Feb '04

I just installed the downloadable version of Squeak 3.5 on a Windows XP machine. I can start Squeak on local images (i.e. on the C: drive). that is, this works from a cmd prompt: cd /d c:\squeak squeak.exe squeak.image I tried to open an image several ways, but am not able to start up images on network shares. For instance, this doesn't work: c:\squeak\squeak.exe \\ned\homes\Squeak\3.6\squeak.image even though I can in fact see the image file in the explorer. Squeak complains that it can't find the file. Why doesn't this work? If I map a drive it works, though very very slowly: map h: \\ned\homes c:\squeak\squeak.exe h:\Squeak\3.6\squeak.image But I was trying to avoid mapped drives, since they seem to be just "tacked on" to NT (i.e. they have to go through a translation to become native resource names, etc.) and they're something else that can break. -- Ned Konz http://bike-nomad.com GPG key ID: BEEA7EFE

[BUG] TextPropertiesMorph - overflow
by Webb McDonald 22 Jan '04

22 Jan '04

If you have a text that's substantially large, opening a TextPropertiesMorph to add color becomes impossible. The window opens as large as your full text - is there an alternative? I believe it needs a scrollbar! Can I make this fix and turn it in? also - GeeMail gets blown away when you open TextPropertiesMorph... but I'm not sure where its best to begin with this, (it could call for a rethinking of TextPropertiesMorph - make edits to the existing TextMorph instead of a tmp copy? - evidently this problem with GeeMail occurs btwn the transition from 'TextPlusMorph', to tmp TextMorph, and back to TextPlusMorph). If no one has an opinion on this then I'll go ahead and do these changes! (or please inform me otherwise) - adios, Webb McDonald 1324481.14 662809.63

[FIX][REPOST] slightProgress-sm
by simon＠joyful.com 16 Jan '04

16 Jan '04

I file this in to every new image to get more accurate project loading progress bars, and it still works for me. So I thought I'd repost. from preamble: "Change Set: SlightProgress-sm Date: 3 Nov 2001 Author: Simon Michael Make project loading progress indicators slightly more accurate by storing timing data separately for local & remote downloads. After loading a few projects you should notice less flickering, especially when downloading large projects over a slow link. Also fixes the spelling of the TranslucentProgressMorph class."!

[BUG] Vars missing in debugger...
by goran.krampe＠bluefish.se 07 Jan '04

07 Jan '04

Hi! I have no idea why I haven't seen this before but try this do-it in a workspace: 'asd' do: [:cll | self halt] ...now - where is the cll var in the debugger pane? It should be down in the right pane - it is in my old email image (3.2) at least. Haven't tried tracking or looking any further - perhaps someone else knows this MUCH better. :) regards, Göran

"Lex Spoon" <lex(a)cc.gatech.edu> replied: But do you really want to disallow 'as yet unclassified' methods? I have made it a rule in my Smalltalk programming *never* to perpetrate an 'as yet unclassified' method myself. Once or twice when I was getting started or felt really lazy, I did that. Mea culpa, mea culpa, mea maxima culpa. Never again. The only reason I can see for not classifying a method that you are about to write is because you don't know what it is going to be about, and in that case, why are you writing it? As a _reader_ of Smalltalk, I find 'as yet unclassified' methods such a pain (not least because they are usually without any helpful comments either) that YES I darned well WOULD like to disallow 'as yet unclassified' methods. There is _always_ something better to put a method under than 'as yet unclassified'. If nothing else, 'unclassified command' -vs- 'unclassified query' would be a clue about whether the thing was supposed to change the receiver's state or not. And I like having a class and category around to muck in. When I'm working with students, it's nice if _they_ are using class category 'JoeStudent-461' and _I_ are using 'ROK-461' so that I can file their mucking-around category into my image and vice versa. If we all mucked around in the same category it wouldn't be so nice. Creating a class category and a class is a good beginning exercise in using a Browser. My daughters are nearly five and a bit over seven and a half. It's so _easy_ to do everything for them; it feels so unkind to insist "YOU can do that. No, you CAN do that. You'd be surprised what you can do. Go on, try." It is not clear to me that it is a kindness to provide "canned" "no-brainer" defaults.

[Bug] The ever-widening PluggableTextMorph
by Ken Causey 31 Dec '03

31 Dec '03

( PluggableTextMorph on: nil text: nil accept: nil readSelection: nil menu: nil ) extent: 50@100; editString: 'This is some really long text that will hopefully cause the PTM to wrap and a scollbar appear'; hResizing: #shrinkWrap; openInWorld. Now either extend the text or just wiggle the scrollbar and watch the PluggableTextMorph widen and widen. The hResizing: #shrinkWrap seems to lead to this behaviour. Ken
