[Election 2008] Hunting down voters... please help me
by goran＠krampe.se 02 Mar '08

02 Mar '08

Hi all! Ok, I have fixed a few "mishaps" with voters not receiving ballots (perhaps spam filtering or whatever), voters having old emails on SqP, incorrect syntax for email, voters having duplicate accounts on SqP etc etc. Now I have two lists left that I would appreciate some help with, first some accounts that do not have an email: http://people.squeakfoundation.org/person/gboccoleri/ http://people.squeakfoundation.org/person/mayuresh/ http://people.squeakfoundation.org/person/masm/ http://people.squeakfoundation.org/person/mds/ http://people.squeakfoundation.org/person/Indigo83/ I came up somewhat empty when checking my squeak-dev archive, if you can get these guys to email me in private OR if you know their correct email address - mail it to me. Otherwise they will not get a ballot. Secondly, we got a report of bounces from Andrew at Cornell (thanks!): stregone(a)att.net squeak-people(a)forum-mail.net calmosoft(a)freemail.hu jan(a)impara.de andrew.catton(a)ubc.ca filip.stadnik(a)atlas.cz masaakim(a)tf7.so-net.ne.jp daltman(a)uol.com.ar squeak(a)vanrooijen.com a_chaoidh(a)hotmail.com edjason(a)britishlibrary.net jrsotty(a)frfee.fr jigme1968(a)tom.com 09446209-926a-4c04-b08e-101456ba64e5 squeak(a)ajr.e4ward.com xradionut(a)mac.com chris.schreiner(a)online.no ted-peo(a)legenda.com Haruko.Mitake(a)jp.yokogawa.com I fixed four myself (not listed above) but hope to get some help with this list. Same here - if you can get them to email me in private OR if you know their correct address - mail me. regards, Göran

Re: [squeak-dev] [ANN] An Example Installer script for preparing 3.10 Dev for VM building
by Ken G. Brown 02 Mar '08

Good point. Right now my example isn't in shape to do a completely automatic run but I will work on this and see if I can make it happen. I had some issues where I needed to download things to my local drive, don't know exactly how to handle those at the moment. Thx, Ken G.

Squeak News team Report - Feb 2008
by Ron Teitelbaum 02 Mar '08

02 Mar '08

Hello Everybody, This is your monthly News report for Feb 2008. A cold snap has locked the east coast. There has been lots of snow and ice, but things are starting to thaw. I saw some of my bees flying just the other day so spring is on the way. And now the news: We had 13,004 hits for the leap month of February. The one missing day from (29 instead of 30) is not enough to account for the drop in numbers. It must be the lack of good pictures from Craig. We are down 2000 hits from last month and 25,000 from the month of PARC pictures. Our top articles were The Golight: Tool Support for Test-Drive <http://weeklysqueak.wordpress.com/2008/02/07/the-golight-tool-support-for-t est-driven-development/> 3,398 hits Qwaq releases Hydra multi-core Squeak VM <http://weeklysqueak.wordpress.com/2008/02/21/qwaq-releases-hydra-multi-core -squeak-vm/> 2,329 hits Hashing in Smalltalk <http://weeklysqueak.wordpress.com/2008/02/25/hashing-in-smalltalk/> 769 hits IANAL - But they are! SFLC Guide to FOSS <http://weeklysqueak.wordpress.com/2008/02/15/ianal-but-they-are-sflc-guide- to-foss-legal-issues/> 580 hits We had 9 articles in February, which is not bad. I would like to thank Klaus Witzel for helping to find good stories to post. That has been very helpful to get our numbers up. Like Klaus if you have suggestions for things you would like to see posted, please feel free to drop the News Team a line. On the Political front, the Squeak Election Team Headed by Göran Krampe has done a wonderful job getting the Squeak Foundation Board 2008 Election organized and encouraging participation from both the candidates and the community. The News team looks forward to posting an article about the results. Please don't forget to vote! Voting helps to show your support for the Squeak Foundation and all the hard work that the Board does for the community. You can find out more about the election at: http://wiki.squeak.org/squeak/6025 Happy Squeaking, I'm Ron Teitelbaum your Squeak News Team Leader. Have a good day!

[ANN] An Example Installer script for preparing 3.10 Dev for VM building
by Ken G. Brown 02 Mar '08

02 Mar '08

I've created this Installer script in order to easily build up a an image from a fresh 3.10 Dev image, doing the stuff that is required for setting up the image for building plugins or a VM on Mac. Please let me know of any improvements, better ways of doing things, or nifty additions. Cut and paste this script into a file named myInstallerScript-1.0.text or whatever you want, but some changes may be required to the script then. Enjoy! Ken G.

Setting 3.10 Dev image up for VM compiling
by Ken G. Brown 02 Mar '08

02 Mar '08

sq3.10-7159dev08.02.3 and Squeak 3.8.18beta1U.app on Mac. While following the instructions in the readme which lives in the sourcetree at http://squeakvm.org/svn/squeak/trunk/platforms/Mac%20OS/vm/Documentation/re… and after loading Keith's Level Playing Field, Balloon3D, FFI, and VMMaker 3.8b6, I have found the following items of interest: As noted in the readme, 1. VMM38-gc-instrument-image.1.cs is already there in 3.10 Dev 2. VMM38-64bit-imageUpdates.1.cs is already there in 3.10 Dev As well, 3. JMM-fixBiasToGrow.1.cs, and bigCursor-bf.1.cs load in with with VMMaker-tpr.58 changeSet which comes with VMMaker 3.8b6 However, 4. VmUpdates-dtl stuff is not there, and needs loaded Maybe this will help save someone some time and uncertainty. Ken G. Brown

You could use FFI calls to set the cursor position, if you really need to influence the hardware cursor. - Bert -

[Patch] Class>>#bindingOf: with inheritance priority over Smalltalk global variables
by Klaus D. Witzel 01 Mar '08

01 Mar '08

I want to give priority of a class' hierarchy's bindings over that of (self environment) when the latter defaults to the Smalltalk global dictionary (as is the case today in most images). Attached is a patch which supports SharedPool as it was introduced in - http://lists.squeakfoundation.org/pipermail/squeak-dev/2003-May/058391.html But with the patch the scope of global variables is now as follows: 1] classPool 2] sharedPools 3] environment if ~~ Smalltalk 4] superclass 5] Smalltalk (or equivalently, nil environment) Without the patch and as is today, item 5] takes precedence over the superclass hierarchy item 4] whenever (aClass environment == Smalltalk) is the default. With the patch inheritance has priority. It can for example be made possible to "shadow" any global variable by using a SharedPool and class initialization code, and that is now inherited. Feedback is appreciated; also if you want see the patch in the next release. /Klaus

Re: [squeak-dev] Closing a socket for port re-use - dumb question
by Bill Schwab 01 Mar '08

01 Mar '08

Andreas, Randal, ===================================== Randal wrote: Not sure in the windows world, but by design, sockets closed are held closed for two minutes in case late packets arrive. If you don't care about that you can set "socket reuse" on the socket before you close it. *--------------------------------------------------------------------- By that, do you mean something like "socket setOption: 'SO_REUSEADDR' value: true." that I just found in the image? There is also an SO_REUSEPORT which is probably more what I want. I will read up on them shortly. Of course, there is Andreas' example which appears to suggest that there is no problem. All I remember is that I had problems, got conflicting advice, and ultimately found ephemeral ports solved my immediate (at the time) problem at the expense of some work and firewall hassles. I suspect the reuse options are the answer. Thanks for the pointers!!! Bill Wilhelm K.
