Box-Admins Team Report for February, 2009
by Ken Causey 06 Mar '09

06 Mar '09

The box-admins team is reponsible for seeing that the community shared server is maintained and setting up any new features to be hosted on that server. For February, 2009: We received a complain from Undernet that an undesirable bot was accessing their IRC network from our server. At first I was skeptical since I couldn't find any indication on the server that any such thing was happening. But in the end I did find a bot service running under the name 'bash'. I killed it and remove the cron entry which started it. I still don't know how it got on the server. Some timestamps such it may have happened during the difficulty we had with the server in October. As far as I can tell other than running this bot nothing else was done. Göran later ran chkrootkit and rkhunter and found nothing. For now we are keeping our eyes open and have held on to the installed files for any further analysis that comes to mind. Otherwise the server has been running smoothly and continuously since the trouble in October. Some discussion of replacing the server has begun although it is early in the process. First we have to determine what is a reasonable budget and I'm hopeful that with the new Leadership team we can have greater transparency in this area. I want to thank the community for the monetary support needed to fund the server and remind you that the bills continue to appear and that you can currently contribute to the hosting costs by going to http://www.squeak.org/Foundation/SupportSqueak/ and purchasing a Squeak badge. Note that a donation here may be used for other Squeak community services including but not limited to development, development infrastructure, and promotion of Squeak. The services being hosted have continued to grow and include (but are not limited to): http://www.squeak.org/ SqueakMap - http://map.squeak.org/ http://ftp.squeak.org/ http://lists.squeakfoundation.org/ http://source.squeakfoundation.org/ http://map.squeak.org/ https://svn.squeak.org/ http://update.squeakfoundation.org/ http://wiki.squeak.org/ http://bugs.squeak.org/ and DNS services for squeak.org and squeakfoundation.org domain names.

Re: [squeak-dev] Elements - a Scratch-like Smalltalk
by Jens Moenig 05 Mar '09

Hi Jecel, representing a "show result" as new object tile is an excellent suggestion! I had been considering something like this but couldn't come up with a (quick and consistent) paradigm. Currently the element tiles themselves don't actually store any values, let alone bytecode. They're just place-holders for ... words, really. Similar to (or rather the exact same as) text typed into a workspace or browser scripting pane, they don't ever point to "live" objects, like Etoys-tiles or Scratch reporter blocks do. Therefore I'm not so sure if allowing any object to become an "object element" really would be easy or even feasible. But I'll definitely keep on thinking hard about this, and am open to any ideas.

Elements - a Scratch-like Smalltalk
by Jens Moenig 05 Mar '09

05 Mar '09

Hi Squeakers, I have created an experimental Squeak-Smalltalk GUI which lets you program much like you would in Scratch, i.e. by snapping blocks together. You can even also through (and change) the Scratch Source Code by using these block-like syntax elements: http://www.chirp.scratchr.org/blog/?p=24. Any feedback is most welcome. Also, if anybody would like to join up in pursuing this idea, let me know! -Jens -- View this message in context: http://www.nabble.com/Elements---a-Scratch-like-Smalltalk-tp22348823p223488… Sent from the Squeak - Dev mailing list archive at Nabble.com.

Mac Carbon VM 4.0.0b1 Closure Compiler Aware with Alien support
by John M McIntosh 04 Mar '09

04 Mar '09

Yes it compiles, yes after a bit of poking I could take a Squeak3.9- final-7067.image and build a closure aware image. No I could not do that without poking a bit, however I hope that we'll resolve the problems in a day or two. Yes, I could take a Pharo0.1Core-10243.image and after more poking could generate a closure aware Pharo image. At this time the 4.0.0b1 VM is not publicly available, another day or two of cross checking is required, I've asked the Pharo team to review my changes and the changes from Eliot. I've also asked Eliot to supply some fixes so we can recompile the Squeak3.9-final-7067 image without problems. I cannot speak for the 3.10 or 3.11 images, other parties will need to pursue any work to make them closure aware. Tomorrow I'll poke at making the iPhone VM closure aware, however any iPhone image relies on the Pharo team resolving what the change sets should be to make the image closure aware. -- = = = ======================================================================== John M.

Hi all! Trying to whip up a few more votes so that we reach 187 - the number of votes last year. If you *did* receive my test mail with subject line: "[Election] Test mail for upcoming vote" ...but not a ballot with the subject line: "CIVS Poll now available for voting: Squeak Leadership Team 2009 Election" ...then email me privately! regards, Göran

Announcements?
by Andreas Raab 04 Mar '09

04 Mar '09

Folks - I've been seeing references to the Announcements framework popping up in various places. From what I've seen it looks like it might be similar to an idea that I had never fully developed in Tweak. Unfortunately, googling for anything + "announcements" is basically impossible (lesson: When you choose the name of a framework, think about teh google!). Does anyone have a canonical site for Announcements handy? Is there a Squeak implementation? Cheers, - Andreas

CurlPlugin and cookies
by Simon Kirk 04 Mar '09

04 Mar '09

Hi all. Has anybody had any joy with CurlPlugin with respect to getting it to handle cookies? As far as I can tell no matter what runes I throw at it it's steadfastly refusing to read the cookies coming in the server response I'm getting, or alternatively steadfastly refusing to send those cookies onwards to the next request. All pointers more than gratefully received.

dynamic GUI
by Ralph Boland 04 Mar '09

04 Mar '09

I have a GUI a section of which is a morph containing various GUI components, mainly buttons, radio buttons, and check boxes. Currently all GUI components associated with the section morph are visible all the time even though only a subset of them are in use at any given time. The subset of components that are active at a given point is determined by a menu selection made by the user. The menu is attached to a button which is part of the section morph itself though I don't think that matters. How do I either: a) Disable the GUI components that are unused at a given point. b) (preferred) Redisplay the entire section morph. I know how to determine which GUI components should be selected for use when a new version of the morph is created (obviously). What I don't know is how to remove the version of the morph being displayed from the screen and replace it on the screen with the new version which I just created. Note that in general some of the section's GUI components will remain active during the section morph replacement and these components will maintain their values and effects. Thus one possibility is to keep these components and just assign them to the replacement section morph. I don't know what is involved in doing this or if it makes sense. Not that b) is much like using tabs to select pages with one of the differences being that the selection is made using a menu instead of tabs. Sorry for not voting. I tried a few minutes ago but got an error when I tried. I assume that I missed the deadline. Ralph Boland -- When a woman becomes sexually aroused the necessary blood flows from her heart.
