Re-2: [squeak-dev] [Fwd: [Webteam] Suggestion for Squeak Website]

Hallo Barbara, try a right click on your painting. There should raise a list where you find in the lower part a point called "export". This you can use to store an image-file that is printable.

Re: [squeak-dev] 3.10 Dev - Unable to load VMMaker 3.8b6.1 from Universes

All OmniBrowser based tools will be closed. Are you ready? If you see that, it's because you clicked on 'select upgrades'. Since there were some OmniBrowser newer versions on the universes, they have been selected for installation. If you only want to install FFI, just click on 'update list from network' and then select FFI. If FFI does not install, I can't help you, you have to talk to the maintainer. Bye -- Damien Cassou

Use "export ..." in the red menu icon of halo menu of your sketch and then save it as a BMP/EPS/JPG/GIF file. If you sketch consists of multiple pieces, use the "grab patch" or lasso tool (from Supplies) to compose single sketch out of your whole drawing and then export it as a picture file. Subbu

[Election 2008] Campaigning running out! Election starts tomorrow!
by goran＠krampe.se 29 Feb '08

29 Feb '08

Hi all! Tomorrow at 18.00 UTC the election will start and run for a full week. You will get your ballot via email if you are registered on SqP with a working email address and a ranking of Apprentice or higher. Make sure to click on the link in the email and vote until 8 march 18.00 UTC. That's it! :) The Q&A: Time is short for the candidates to answer the Q&A. Only 6 of the 12 candidates have answered it so far (I hope I didn't miss anyone) and only ONE (thanks Matthew!) has posted a campaigning statement to SqP. But if you have answered the Q&A the campaigning statement is possibly already covered by that. Note though that since the election runs for a full week it is by all means NOT TOO LATE to answer the Q&A! :) I have sent personal email to all candidates reminding them about it, but it is of course not mandatory to answer it in any way. ;) IMPORTANT: In order to vote - be sure to confirm that you have an account on http://people.squeakfoundation.org and that your email address is up to date. If you are not already registered on the site do so as soon as possible. Include information about your participation in the Squeak community to aid everyone in determining your appropriate certification. If you have misplaced your people.squeakfoundation.org password there is a link on the login page to allow you to reset it. When the voting period starts all voters will receive an email with instructions and a link to the voting website. Over and out, Göran "The Election PITA 2008" Krampe

Rearranging variables in interpreter struct (lil speedup)
by Igor Stasenko 29 Feb '08

29 Feb '08

I just wondering, what if i place variables in interpreter struct in specific order, not in order, which code generator produces. Since speed impact expected to be very small (if any), i used following code to measure difference. [ 5 timesRepeat: [ 1 tinyBenchmarks] ] timeToRun This is HydraVM without attempts to arrange interpreters ivars: 28921 28863 28863 This build shows a small slowdown (i placed all big-sized arrays at tail, and #stackTop #successFlag at head) 28938 28940 With this build i placed methodCache ivar to come first. 28279 28264 so, difference is small but noticeable. Placing methodCache first gives roughly 1-2% speedup. I don't really sure if this worth experimenting at all. And i'm lacking of knowledge of different CPU/compiler details to predict that these changes will take effect on different CPUs (mine is AMD Athlon series). If you having any ideas, concerning given changes, or any other optimizations which can probably improve speed, please feel free to uncover details/guidelines. -- Best regards, Igor Stasenko AKA sig.

Squeak Win95/Win98 support
by Andreas Raab 29 Feb '08

29 Feb '08

Hi - I'm not sure this matters for anyone but just so you know some recent changes to the Win32 Squeak VM for making it fully Unicode aware have broken the support for Win95 and Win98. Since I am not planning to spend any time whatsoever on supporting these versions any longer[*1], you will have to use older (pre-3.10.x) VMs in order to run on these Windows versions. I recommend the 3.7.x series which was a particularly stable vintage ;-) If anyone is interested in supporting Win95/Win98 specifically, drop me a note and we can work something out (maybe a branch on SqueakVM.org). Cheers, - Andreas [*1] Actually I may spend some time getting rid of all the crude workarounds that were necessary to support Win95 in the first place.

0006966: VMMakerTool fails to open due to EnhancedSerialPlugin use of deprecated methods
by Ken G. Brown 28 Feb '08

28 Feb '08

Mantis <http://bugs.squeak.org/view.php?id=6966> I have uploaded a changeset containing small fixes to Mantis 6966. ----- Running sq3.10-7159dev08.02.1 with Level Playing Field scripts applied, Summary 0006966: VMMakerTool fails to open due to EnhancedSerialPlugin use of old access to Smalltalk>>platformName Description In VMConstruction-Plugins category, SerialExtended... classes still use some deprecated access methods to Smalltalk system dictionary. Smalltalk #platformName has been changed to SmalltalkImage current # platformName, and Smalltalk #osVersion has been changed to SmalltalkImage current #osVersion. Steps To Reproduce Load EnhancedSerialPorts-JMM.11.cs.gz from <http://homepage.mac.com/WebObjects/FileSharing.woa/68/wo/HUJZNDaamKtM2XXk.1…>, FFI and VMMaker into sq3.10-7159dev08.02.1 after applying Keith's Level Playing Field changes, attempt VMMakerTool openInWorld.
