David T. Lewis uploaded a new version of Chronology-Core to project The Trunk: http://source.squeak.org/trunk/Chronology-Core-dtl.80.mcz ==================== Summary ==================== Name: Chronology-Core-dtl.80 Author: dtl Time: 19 May 2022, 12:03:05.720962 pm UUID: 1b1b97c4-bc35-408d-b548-f0d0376a0808 Ancestors: Chronology-Core-dtl.79 Change DateAndTime>>offset: to be compliant with the ANSI draft spec. The offset: method should answer an instance equivalent to the receiver, where equivalent means having the same UTC time. Let #offset: adopt the prior behavior of #utcOffset: and let #utcOffset: be a compatibility synonym for #offset:. Add #asLocalAt: to the squeak protocol and let it implement the prior behavior of #offset: Change existing code and tests to use #asLocalAt: but otherwise retain existing behavior.

upcoming conferences and events
by Yoshiki Ohshima 27 Oct '22

27 Oct '22

HI, There are a few gatherings in the coming few months. One is Smalltalks in Argentina, and I know Vanessa and (I think) Dan is going, (and probably many others) are going from outside of Argentina, and of course there will be many Argentinian Smalltalkers. Also there is SPLASH. I am going to attend in person, though our presentation is not directly related to Smalltalk or Squeak (I still consider it indirectly related to Smalltalk ideas) . It sounds though that some people I'd expect to meet there are not coming in person... But there must be quite a few people I have not checked with! Please let me know if you are going! -- -- Yoshiki

remote.3 in Carol and Alice gets shortened.#provideFor:/#acceptFrom: inplied in switching p2 to use remote.3 into Bob. This is interesting. The 2 little #whenMoreResolved: are no longer needed from Bob back to Alice, so the cleanUp with some GC Messages. The 2 little #whenMoreResolved: back to Carol are now active. The final slide.

For those still following along I’d say I appreciate you, I appreciate your interest, I appreciate your consideration, I appreciate your discernment! promise.1 now points to remote.2 and remote.1 is totally cleaned up in Carol while the 2nd message is all that is referencing remote.2 in Alice. Bob’s still waiting to be #greet:ed… Now the 2nd message (what was it? #doYouLikeHer perhaps…) has been disgorged to Bob with the establishment of remote.4 in Alice.

Carrying on… In this slide we see the little #whenMoreResolved: in Carol has hit r1 and now p1 points to r2 to the message continuation in Bob. Due to r1 no longer being referenced a GCAnswer is sent to Alice to let her know r1 is no longer referenced. I’ve just realized that my table description may be wrong…sigh. As a GCAnswer is sent for r1, then the Burgundy/Pink tables must be Questions/Answers. Answers would be Pink and outgoing ref and GCAnswer cleans that entry. I’ll take a closer look in a minute… Ok! As the resolver for r1 is no longer referenced in Alice, a GCExport is sent to Carol to cleanup the entry in Carol’s Exports table. So Exports must be Yellow. Yes I was all turned around. My apologies to those trying to follow. This makes much more sense semantically.

[ANN] Objectland - The Worlds of Squeak
by christoph.thiede＠student.hpi.uni-potsdam.de 21 Oct '22

21 Oct '22

Hi all! :-) I just finally uploaded the last missing piece of Objectland (aka "The Worlds of Squeak") to the Trunk today! See MorphicExtras-ct.338. The set of colorful examples for Morphic, Sounds, and more which were inspired by the Squeak 3.7 release image is now completely contained in your up-to-date image. You can open it from the Apps menu in the docking bar, or by selecting the "Demo" category in the object bin. Some of my personal highlights include the comeback of the BlobMorph, the demonstration of text flows in Morphic, and the ScorePlayerMorph with The Beatles's "Let It Be". I hope you will have some fun exploring and playing with the examples, just like I had a lot of fun while (re)constructing them. It should look well on all common screen sizes (greater than or equal to 800@600) and all common scale factors (see ObjectlandTest class>>#generateProjectScreenshots). Like every good project, nothing is ever perfect, so some slips are pretty much expected -- if you discover any, please just report them and I will try to fix them; or just go ahead and contribute your own examples. :-) Thanks a lot to Marcel (mt), Leon (LM), and Robert (rhi) for their collaboration on this project! Best, Christoph --- Sent from Squeak Inbox Talk
