Squeak Oversight Board 2018 - Time to vote!!
by Ron Teitelbaum 23 Jan '18

23 Jan '18

Hi all, It is time to vote. Please go to your email client and look for an email: Poll: The Squeak Oversight Board 2018 from: Ron Teitelbaum (CIVS poll supervisor) <civs(a)cs.cornell.edu> The VOTER EMAIL could be in your SPAM or JUNK folder please look there! Take the time now to go find your ballot and vote! Description of poll: It's that time again. Time to VOTE for the Squeak Oversight Board. Please take the time to vote!!! The 7 highest ranked odd number of candidates from the list will comprise the Squeak Oversight Board starting from the end of the voting period until the next Board is elected. Remember that your vote is considered as a ranking of all candidates. Voting for "None of the Below" allows you to vote for the people you want most without having to vote for candidates that you do not prefer. Candidates that get fewer votes than "None of the Below" ARE NOT elected to the board. In the case that "None of the Below" is chosen above the 7 candidates needed, the board will have fewer than 7 members for the year. If you don't have a preference between two candidates rank the users with the same rank. Ranking "None of the Below" above other members indicates your desire to vote against the remaining candidates. Select a lower rank than "None of the Below" too! vote against them. Please contact voters(a)squeak.org if you have any questions or for more information. Your question and answer will be posted to squeak-dev. For more information and details, see the official 2018 elections page at http://wiki.squeak.org/squeak/6590 There are some great candidates. Please VOTE!! All the best, Ron Teitelbaum

Apparently, SmalltalkCI downloads the latest trunk image and then applies the updates with "MCMcmUpdater default doUpdate: false". AFAICT, something seems fishy with Kernel-nice.1127 (update-nice.422), at least that's the package that appears to hang when I try to evaluate that statement manually. Image: Squeak6.0alpha latest update: #17412 Current Change Set: Unnamed1 Image format 6521 (32 bit) To reproduce with SmalltalkCI: git@github.com:hpi-swa/smalltalkCI.git && cd smalltalkCI && ./run.sh -s Squeak-trunk --headfull -d Cheers, Max > Max > > Best, > Marcel

Where to put clock and calendar morphs?
by Louis LaBrunda 22 Jan '18

22 Jan '18

Hi All, Especially Tim and Bob, I'm getting close to being ready to share my clock and calendar morphs. For now I have been building them in category: 'RotaryDialMorphs'. My ClockImageMorph is a sub-class of RotaryDialMorph, CalendarDisplayMorph is just a Morph. Should I make my own category to house them or keep them added to 'RotaryDialMorphs'? I'm thinking make my own category but I would like some opinions. Also, as part of making fancy hands for the clock morph, I have a method that draws a 5 point star. For now this is a class method of the clock morph that gets passed a form. I'm thinking maybe it should be an extension of Form, so the star would just be drawn in the form. As such it would probably be better in my own category. To draw a star you specify a starting point (among other things) that corresponds to the lower left hand point of the star. Does this make sense or should it be the top point or center of the star. The center would take some math. How and where do I upload to? Lou -- Louis LaBrunda Keystone Software Corp.

On the performance of our browsers... THEY TICK!
by Marcel Taeumel 22 Jan '18

22 Jan '18

Hi, there. Our browsers (or rather all tools) are stepping. That's bad. See for yourself in #updateListsAndCodeIn: or put a "Transcript showln: #verify" in PluggableListMorph >> #verifyContents. That's why we have to be very careful to add anything new to our tools. Here, #verifyContents makes a full list fetch from the model ... EVERY SECOND! Note this: 1) We have a system change notifier to respond to code changes in our code-centric tools. 2) We have #changed:/#update: to keep the GUI up-to-date in our other ToolBuilder tools/applications. 3) We should get rid of Object >> #stepIn:, #stepAt:in:, #modelWakeUpIn:, #updateListsAndCodeIn:. It might be a legacy from old MVC times. I don't know. It is not required anymore. Best, Marcel P.S.: Also see SystemWindow >> #stepTime and all implementors of #stepTimeIn:. ;-) P.P.S.: Only our Inspector needs it since we have no clue what "changed" means for an arbitrary object.

Re: [squeak-dev] Trunk update broken

Hi Marcel, Hi Max, I think this is related to the latest VM used by SmalltalkCI, which seems to crash on Travis' macOS environment during in-image update. I don't think so. The Travis build runs on Linux and I can reproduce the issue locally on macOS. Max Best, Marcel
