Studies on group effectiveness

http://mobile.nytimes.com/2015/01/18/opinion/sunday/why-some-teams-are-smar… The studies find that smart teams are distinguished by three characteristics, sharing time evenly between members, being good at reading each other's emotional states, and having more women. On-line groups are distinguished by the /same/ three characteristics. Eliot (phone)

[Pharo4] Slots: GTInspector support
by Marcus Denker Jan. 17, 2015

Jan. 17, 2015

Hi, Now GTInspector can inspect objects that use custom Slot definitions. https://pharo.fogbugz.com/f/cases/14741/GTInspector-add-simple-slot-support <https://pharo.fogbugz.com/f/cases/14741/GTInspector-add-simple-slot-support> create a class with he TestSlot (where the ivar lives in the Slot instance and is thus shared over all instances of A): Object subclass: #A slots: { #iv => TestSlot } classVariables: { } category: âPlayground' Inspect A new change âivâ to value (e.g. 5). inspect another "A newâ ==> it should show the value as 5. Thus both reading and writing now is done via the Slot. (as such this require just a very simple change in GT, of course). The GT support of course needs to be improved later: -> we need a view that shows the object âas it really isâ (keep in mind, this object has no VM level instance variable!). -> In the view with the slots they should annotated so we see that it is a slot and can easily navigate to the slot definition -> â¦ I am sure more will be obvious as soon as we use it.

[Pharo4] Slots can now be saved with MC
by Marcus Denker Jan. 17, 2015

Jan. 17, 2015

Hi, After some searching for a solutionâ¦ that does not break backward-compatibility, I found a way to save classes that use slots. - if a class just uses ivar Slots, it saves it 100% backward compatible (e.g. loadable in other systems) - if a class uses a special slot or class var, it saves the definition of the slot as the variable name in the monticello model. - on load it checks if there is a space in a variable name, and if yes â> decode these as Slot/Global var definions. - the code path for non-Slot classes stays largely untouched. This is not beautiful but backward compatibleâ¦ you can even load classes with Slots in Pharo3, it then creates invalid ivar names, which of course means the code does not run but it is readable. e.g. create a class like Object subclass: #A slots: { #iv => TestSlot } classVariables: { } category: 'Playgroundâ (TestSlot is a slot that does not use up space in the instance and instead saves the state in the Slot object, which means all instances share the state. Just a small example) Limitations -> no support for class variables yet -> class instance variables not yet done, either -> nut used much, for sure there will be bugs This is in 4.0 438 Marcus

I believe in Redline. I think it's a very important project, strategically. On Twitter and elsewhere, I am urging contributors to join Redline. It would be something of a tragedy if Redline failed to reach version 1.0. *We need Smalltalk on the JVM.* jamesl wrote > Hi Smalltalkers, > > Redline Smalltalk is not dead although it looks like it. > I recently made the grammar much cleaner and moved to using Antlr4 as well > as cleaning up the > internals.

That sounds awesome Craig, congratulations. If you ever do a video of a reasonably-sized imprinting experiment onto your core-classes image from a modern Squeak image, I will be very interested to see it!

Fixing DNU binding in GT and Nautilus
by stepharo Jan. 16, 2015

Jan. 16, 2015

Hi in nautilus method pane and GT, when I select a global variable such as SystemOrganization and press command B + N I get DNU binding. Apparently this DNU only happen when the name does not match any class substring Transcript or Undeclared will not raise an error because we have classes having name matching the expression. Fixed included. PS: I'm dead after 1h30 train delay (after giving 6 hours lecture) today. So this mail will be sent whenever I get connected. Stef

Right now there is support for Opal but not for the old Compiler in Spur images. GTInspector and TxWorkspace does direct references to the old compiler in Pharo-40445, for example, in GLMListingPresentation>>#withSmalltalkSearch. This is a pain because I am using spur images for my developments and I can't use some features of GTInspector. In addition, the old Compiler will be removed by default from the image in the next 6 months, so these features will not work in non spur images soon. Compiler references can be replaced, for example, by "self class compiler" or "Smalltalk compiler" depending on which compiler you want (one specific to the class with the specific class settings or a generic one).
