Unofficial status report
by goran.krampe＠bluefish.se 04 Apr '05

04 Apr '05

Hi everyone! This *unofficial* report is just to keep everyone a bit updated. Unofficial means that this report is written by me personally and the other Coordinators (Doug, Marcus, Cees) haven't read it and may disagree :). Things in this report: 1. Squeak 3.8 Real Soon Now. :) 2. Teams churning. 3. The planning of 3.9 and beyond. 4. New VMs! 64 bits here we come! Squeak 3.8 ------------- The release has now slipped a whole month, but hey :), Michael Rueger will hopefully soon get it out. AFAIK it is ready to go and only some image last-minute-preparation is left to do. Michael? Stressed out? ;) Teams ------- We now have a bunch of Teams working on separate tasks (see http://anakin.bluefish.se/castaways/6) , and the team model seems quite promising so far. The teams all have their own mailinglists so a lot of that traffic has left squeak-dev - so don't be fooled and think things aren't moving along. The following is my personal possibly incorrect :) perception of what is happening in the Teams at the moment (feel free to correct me guys). I am not following all teams, but have skimmed the mls of those I don't follow: - WebSite (9 subscried to ml). This team has set up a Smallwiki for collaboration on box1 and seems to be starting to itch to get the new website deployed, but I have not yet seen the current version (I think it is temporarily offline). Looking forward to it though! - MorphicSplitters (15 subscribed to ml). Seems to be lots of activity by looking at the ml acrhive. This team is also quite busy exploring tools for doing analysis, including Dan's code and Daniel Vainsenchers MudPie. Juan Vuletich seems to be the main heavylifter at the moment and wow, I look forward to see what comes out of this team! - ToolBuilder (32 subscribed to ml). This project started out with a bang, but the ml has been mostly silent during march. I don't think that means anything in particular but I personally look forward to get ToolBuilder installed as a package in Basic in the 3.9 alpha stream ASAP, Brian, you hear me? :) The reasoning for that is to make the API available for all of us so that we can start to program against it under 3.9 which in turn is important because in later releases (4.0 or 4.1 or whatever) Morphic will turn into a package (MorphicSplitters) and then tools that hasn't been ported to using ToolBuilder will become inoperational without Morphic installed. - Packages (25 subscribed to ml). This is a team I am part of and we have made some initial deicisons (for example to use PackageInfo as it stands today) and also discussed and decided on a way on how SqueakMap and Universes can be united/merged/whatever. For details on that, check the archive. Avi has also created a page on the Swiki where Squeakers can sign up if interested in helping with splitting out or maintaining (or co-maintaining) a part of current Squeak Basic (http://minnow.cc.gatech.edu/squeak/5641). Please people, go there and sign up! The actual "doing it" hasn't begun yet, but I feel it will soon. Avi? Whaddayasay, time to push some PIs into 3.9alpha? :) - Modules (51 subscribed to ml). This team is led by Dan Ingalls and is focused on delivering a module system "for tomorrow". The team started with a very good inventory of available technology and ideas (http://minnow.cc.gatech.edu/squeak/5608) and is now moving over from analysis to synthesis. :) It will be interesting to see what happens now - IMHO there are a LOT of different aspects here, and to find common ground can get real tricksy. But I have trust in Dan. ;) The inventory in itself is a very good part way result and you can learn a lot just by reading those. - Janitors (11 subscribed to ml). The janitors are doing us a great service and with Ken at the helms I feel safe that the process of fixes and bugs will gradually move to a better state. One of the things the janitors are doing is that they catch all reports and fixes posted to squeak-dev and move them over to Mantis. So people, remember, it is Mantis we should use from now on. :) The team has also written a good guide on how to report stuff in Mantis. - v 3.9 (9 subscribed to ml). Doug Way is the release leader for 3.9 and there is a plan for it on the Swiki (http://minnow.cc.gatech.edu/squeak/5645). The work on 3.9 hasn't kicked into gear just yet, but as the teams (Packages, ToolBuilder) get moving and we get the Harvesting started again (Janitors, what are your thoughts on that? Or Doug?) I think it will pick up. And with Doug leading it I am not worried. :) Planned release is in june. - FileArea and Box1Administration are small teams and nothing much to report. Box1 seems to be humming along fine and Bruce is doing a great job as always keeping the file area up to date. If you haven't noticed this is the current place to find Squeak: http://box1.squeakfoundation.org/files/ ...and if you want to mirror it, read: http://box1.squeakfoundation.org/files/MIRRORING.txt In my opinion all teams seem to be doing quite good. The archives of the mls are available here: http://discuss.squeakfoundation.org I don't think we need more teams at the moment - enough work going on to keep us all busy - but if there are new teams brewing out there, then feel free to contact us Coordinators and see if we can form an official team. I know of at least one such team idea that has been discussed. 3.9 and beyond ----------------- The plan for 3.9 is mostly set and 3.9 will turn out as a more or less classic Squeak release with the exception of the result from the Packages team which makes it different from previous releases. But what happens then? What about 4.0 or 4.1? As we described earlier the result of MorphicSplitters was meant to go in *first thing* in the release after 3.9. Since then the discussion about the new image format was brought up - and given that discussion at least I am personally leaning towards this plan: 4.0 = Let's make a release more or less immediately after 3.9 which is identical to 3.9 but with the new image format and related changes. It seems like a logical move. Tim? Reasonable? How about max 1 month after 3.9, which would mean late july? 4.1 = This will then be the release with the result from MorphicSplitters and thus we are buying them a little bit more time. The plan was to push that stuff in as the first thing and if we open the alpha stream of 4.1 after release of 4.0 then that would mean... say 1st august? What do the splitters say about that? Sounds doable? At the moment I can't find the thread discussing this, so please correct me if you think the above is wrong. New VMs! ----------- Those of you that track vm-dev (or read the announcement today on squeak-dev :)) are aware of that Ian Piumarta has been working hard lately. First we got a fresh release of 3.7 with a fix for the annoying 2Gb bug (manifesting as trouble loading ImageSegments (like SqueakMap for example) on selected platforms) and some rearrangements in the source tree that now includes a full generated default src thus removing the need for manually setting up VMMaker if you just want to build a tagged release directly from SVN. Very nice work Ian! Then today - as you saw in his posting "64-bit VMs" - Ian posted that the 64-bit stuff finally went into the trunk! Yiha. So there are now 64-bit goodness ready for download! Find it all here: http://squeak.hpl.hp.com/squeak64/dist3/ Hmmm, now I just have to find a 64-bit machine to use it on. And let's just hope this isn't a 1st april joke. ;) Over and out, Göran

Below are the most recent 5 articles that were posted on Squeak People (http://people.squeakfoundation.org/). Apart from the articles, you will find people's diary entries there, and an overview of the Squeak community: who is doing what, people's "standing", etcetera. If you don't have an account, please join - we're interested in getting to know you better! This message is posted automatically every week by a dirty shell script. _________________________________________________________________ Date: 2005-02-20 21:46:55 Author: lexspoon Title: Squeak as a Commons Before we can organize Squeak, we must answer: "What is Squeak?" This article defines Squeak as a commons where many individual projects collaborate. The article sketches some of the subgroups using Squeak, and proposes an organizational structure based around giving representation to all of these subgroups. _________________________________________________________________ Date: 2005-01-27 15:49:25 Author: gokr Title: Taming the translation beast! Now - I have just started figuring out how to translate my [1]Homepage Builder application to english and of course ended up digging into the translation stuff. This is a short (well, kinda) report on what I found, how to use what we have, and what I think we need to fix. _________________________________________________________________ Date: 2005-01-10 04:23:15 Author: elvislives Title: squeak logo lookalike Hi, _________________________________________________________________ Date: 2004-12-30 16:37:02 Author: jj Title: Boosting Squeak: RockSolid images I have read the "rant" and "unrant" subject with a mix of uneasiness (embarrassment) and fear. The "Rant" thread began on the 15th of december 2004, and produced a lot of discussion. I will not summarize the thread, because a lot of people read it. Instead, I will go forward and try to find a pragmatic and constructive of helping the community (and yes, I am also very bold and handosome :) << ironic comment). _________________________________________________________________ Date: 2004-12-20 00:34:35 Author: cdegroot Title: Terminus is up'n'running Terminus, the little system I cobbled up to export Squeak People's account and web-of-trust information, is up and running.

graphic designers: trash can icon!!
by Lex Spoon 04 Apr '05

04 Apr '05

The current trash can icon in Squeak does not look right if your background is non-white. I have played a little with trying to fix it, but this is beyond my graphics tweaking skills. Does anyone know how to fix the thing so that it looks okay on an arbitrary background? Or, is there a trashcan icon we can steal from somewhere else? Or does someone want to draw a new one? Don't forget there are really two icons: closed can, and open can. -Lex

Finding a method.
by Michael van der Gulik 03 Apr '05

03 Apr '05

Hi all. When coding, I'm often wanting to go to a specific method at a specific class. Is there a shortcut to do so? E.g. I just want to press ALT-something from anywhere (i.e. a global keystroke), and then type in 'MyClass>>myMethod', which will pop up a browser on that method. Preferably, it would do so without me having to reach over for the mouse. Mikevdg.

Re: [BUG][FIX] WriteBarrier at:put: fix for variable classes
by Chris Muller 03 Apr '05

03 Apr '05

> matter of taste: how much > transparency, and how much permeability, do we actually want? Yes agreed. If I really end up wanting to do it, I'm sure I can write a build method for them in a subclass. I was mainly just wondering whether there were any "system" reasons or caveats to doing it. I guess I'll find out if I try it.. :) > Is there a particular usage of #instVarAt:put: that you're thinking of > that you'd like to have caught? Just one at the moment but its probably no big deal.. To change a value in an inspector and Command+s. Thanks, Chris

[Q] comment in SharedQueue>>peek
by Boris Gaertner 03 Apr '05

03 Apr '05

This question relates to Squeak 3.7. In the instance method peek of SharedQueue we read this: "Answer the object that was sent through the receiver first and has not yet been received by anyone but do not remove it from the receiver. If no object has been sent, suspend the requesting process until one is." The last sentence is wrong. What really happens is that peek returns immediately with nil if no object has been sent. This is clear from the very understandable code, but it can also demonstrated with this code snippet: | sq | sq := SharedQueue new. sq peek A quick look through earlier versions of Squeak (back to 2.3) reveals that this method has not been changed since Squeak 2.3 and there is reason to believe that it was in fact never changed. SharedQueue>>peek is sent in EventSensor>>peekEvent. I think that the comment of the method is wrong (it was credibly simply copied from SharedQueue>>next) and should be fixed. I do not think that the method itself is wrong, but my question is: Are there arguments in favour of a peek that suspends the requestor until an item is put into a shared queue? Your advice will be appreciated. Greetings, Boris

Automatic Startup
by Daniel Salama 03 Apr '05

03 Apr '05

Hi, I've been playing with Squeak to develop web based applications. My intentions are to be able to develop some web based framework which will require that Squeak be running all the time. I'm running Squeak on a linux server. Is it mandatory for the X interface to be running? Can Squeak be started as a daemon process? If not, how would you suggest to configure the machine so each time it's rebooted, Squeak will be launched? Thanks, Daniel Salama
