mandalas (was kaleidoscopes in squeak)
by Jerome Peace 18 Dec '06

18 Dec '06

Hi Edgar, Thanks for the pointer. I found the Mandala's very inspirational. As for mandalas of that complexity in squeak I leave that as an exercise for the children and users of squeak. Tto get a taste of what's becoming possible you could load the Flexicurve project. The redefine stars as a subclass of flexicurve. That done with a curve slider you will get lots of mandala inspiring shapes. Yours in friendship, --Jerome Peace > >kaleidoscopes in squeak >Edgar J.

Start with a short user story. ( e.g. kbd focus)

Start with a short user story.

Get a workspace >From the label menu select 'change title' Then move the cursor out of the title box. Typing will go to the workspace not the title. The title can only be typed with the help of the mouse. The preferences help. There is more work needed.

[ENH]Translucent images in 8 and 16 bit screen resolution
by karl 17 Dec '06

17 Dec '06

Images with alpha translucency will now keep the translucency in 8 and 16 bit screen resolution. (Rotated forms will not, that has to do with WarpBlt internals I don't really understand yet.) It would be nice if people could play with this enhancement and report any issues.

[Fwd: [Webteam] spammers who are operating a drug page within one of your sites!]
by Brad Fuller 17 Dec '06

17 Dec '06

Hi, Does anyone know how to contact the admins gatech servers? See the email below. I don't know the story, but I would think that gatech would at least like to check this out. The sender below is stating that an entity is using the gatech servers to serve up spam. Could you pass this message along to the powers that be? brad -------- Original Message -------- Subject: [Webteam] spammers who are operating a drug page within one of your sites! Date: Sun, 17 Dec 2006 14:24:45 -0000 From: Scotman <scotman4(a)btinternet.com> Organization: none To: <webteam(a)lists.squeakfoundation.org> Hi Guys Please, I'm hopeful you might be able to help. I have been plagued by some idiot spammer who is sending me rubbish though one of my forms. When I look at the home page it is http://coweb.math.gatech.edu:8888 <http://coweb.math.gatech.edu:8888/>. Unfortunately there is no way to contact the operators/owners of the site. All that is on the home page is a logo that says the site is powered by http://minnow.cc.gatech.edu/swiki but when I go to this site, it states that squeak own and operate the site. It is just an endless runaround which is so upsetting. Getting back to my main point the following spam website are for a spam company who sell drugs through the coweb site. http://coweb.math.gatech.edu:8888/abreu/33 It is just so sickening that these evil people should be allowed to operate. These pages have been going for a long time so they have profited from many people. Please contact the people who operate the site and have these pages closed down as soon as possible. Hopefully you can look into this matter of furnish me with any other contact details. Regards Peter

strange behavior in the layout with WrapDirection attribute
by Hilaire Fernandes 17 Dec '06

17 Dec '06

I have found the following example to not work as expected. The problem seems to come from the wrapDirection. In this exemple if you resize the morph, the layout is refresh correctly. I badly need it to work as expected submorph := Morph new color: Color red; layoutPolicy: TableLayout new; listDirection: #leftToRight; cellInset: 10; vResizing: #shrinkWrap; hResizing: #spaceFill; wrapDirection: #topToBottom. 10 timesRepeat: [submorph addMorph: Morph new]. (Morph new color: Color yellow; extent: 300@500; layoutPolicy: TableLayout new; listDirection: #topToBottom; layoutInset: 10; cellInset: 10; addMorphBack: submorph; addMorphBack: (Morph new color: Color orange; vResizing: #spaceFill; hResizing: #spaceFill)) openInWorld

kaleidoscopes in squeak

Hi Edgar, I have homesteaded some pages on Bob's superswiki.

DejaVu fonts with Freetype for 3.9
by Viktor Svub 17 Dec '06

17 Dec '06

I've somehow managed to get the Sophie Freetype fonts working (with the unicode DejaVu free fonts available at http://dejavu.sourceforge.net/wiki/index.php/Download ) in a Squeak 3.9 image /squeak-web-72, on Win32 VM/, but there are still some caveats. The FreetypeFont is usable in the whole system, pretty rendered, but it misses another emhasis' (can't be bold or italic), the line(glyph?) height is much bigger than appropriate for the size given and it can't handle national characters (which are present in the original TTF, part of Latin-2 aka iso-8859-2 codepage). With the same TTF source file and same font size, a HostFont loads a proper emhasis for italic and bold and whats most important: handles all national characters properly (but it's far not as nice and the italic style is virtually unreadable). In this stage, i have no repeatable process to make this work, so you can try to rip the appropriate packages from Sophie and load them (Multilingual-Display, Sophie-FontManager, Freetype-Base and Freetype-Fonts at least -> there may be some cross-references and Undeclared, you can quietly ignore anything Rome-related). I think a can handle the line heights and emphasis issues in a few days/weeks, but i would welcome any guidelines, in particular how to make the complete unicode working. Viktor

Floating point performance

Maybe "almost 80% of the time was spent in basic floating point array operations" is a little exaggerated, but not a lot. What vector processing hardware? The only thing I know of would be trying to use the video card GPU, which could be lots of fun! >Also if you have say a+b*c-d in smalltalk where these are float >array objevcts that would three primitive interactions, converting >that to slang would provide some performance improvements. I'm not sure I understand this statement. Is there enough overhead in the plugin API to justify eliminating a couple of calls, or is there some data representation conversion involved that could be avoided? I haven't read Andrew Greenberg's chapter on "Extending the Squeak Virtual Machine" in detail yet. I kind of skimmed over the sections "The Shape of a Smalltalk Object" and "The Anatomy of a Named Primitive", which I'm sure is where all the good stuff is. Are you saying that some performance improvement in your sample expression could be gained by just coding it in Slang, without translating and compiling it, or have I gone one step too far? - 2441 tallies, 39083 msec. **Tree** 100.0% {39083ms} TClothOxe>>pulse 77.8% {30407ms} TClothOxe>>constrain |77.8% {30407ms} TClothOxe>>constrain: | 14.2% {5550ms} B3DVector3(FloatArray)>>* | 13.9% {5433ms} B3DVector3(FloatArray)>>- | 12.2% {4768ms} B3DVector3Array>>at: | 9.7% {3791ms} TClothOxe>>collide | |9.7% {3791ms} TClothOxe>>collideSphere: | | 3.6% {1407ms} B3DVector3(FloatArray)>>length | | 3.0% {1172ms} B3DVector3(FloatArray)>>- | | 2.9% {1133ms} B3DVector3Array(SequenceableCollection)>>doWithIndex: | | 2.9% {1133ms} B3DVector3Array(SequenceableCollection)>>withIndexDo: | 8.8% {3439ms} B3DVector3(FloatArray)>>+ | 6.3% {2462ms} B3DVector3Array>>at:put: | 5.8% {2267ms} TClothOxe>>constrainGround | |3.2% {1251ms} B3DVector3Array(B3DInplaceArray)>>do: | |2.6% {1016ms} B3DVector3>>y | 3.8% {1485ms} OrderedCollection>>do: | 2.8% {1094ms} primitives 7.0% {2736ms} B3DVector3Array(SequenceableCollection)>>replaceFrom:to:with: |7.0% {2736ms} B3DVector3Array(B3DInplaceArray)>>replaceFrom:to:with:startingAt: | 2.7% {1055ms} B3DVector3Array>>at:put: | 2.5% {977ms} B3DVector3Array>>at: 4.4% {1720ms} Float>>* |2.4% {938ms} B3DVector3(Object)>>adaptToFloat:andSend: |2.0% {782ms} primitives 3.2% {1251ms} B3DVector3(FloatArray)>>- 2.3% {899ms} B3DVector3Array(SequenceableCollection)>>doWithIndex: 2.3% {899ms} B3DVector3Array(SequenceableCollection)>>withIndexDo: **Leaves** 20.1% {7856ms} B3DVector3(FloatArray)>>- 19.8% {7738ms} B3DVector3Array>>at: 15.9% {6214ms} B3DVector3(FloatArray)>>* 11.8% {4612ms} B3DVector3Array>>at:put: 10.9% {4260ms} B3DVector3(FloatArray)>>+ 3.8% {1485ms} OrderedCollection>>do: 2.8% {1094ms} B3DVector3Array(SequenceableCollection)>>withIndexDo: 2.8% {1094ms} TClothOxe>>constrain: 2.6% {1016ms} B3DVector3>>y 2.0% {782ms} Float>>* **Memory** old +386,532 bytes young -551,924 bytes used -165,392 bytes free +165,392 bytes **GCs** full 0 totalling 0ms (0.0% uptime) incr 7133 totalling 1,326ms (3.0% uptime), avg 0.0ms tenures 1 (avg 7133 GCs/tenure) root table 0 overflows
