Seems that Pharo is a magnet for this kind of project. I've been writing one as well and using it to organize my research notes. Does anyone working on personal info mgmt tools want to talk offline? I expect we're running into some of the same issues, both conceptual and technical. Evan

Aggregation framework in MongoTalk?
by phil＠highoctane.be Feb. 18, 2019

Feb. 18, 2019

Is there anyone using the aggregation framework of MongDb through MongoTalk? It uses the aggregate() command, so I was wondering if this could be supported out of the box or if there is a need for an additional Operation. TIA Phil

Retina support in Pharo
by markm Sept. 20, 2018

Sept. 20, 2018

Hi Is it possible to get Pharo (4 or 5) to run with retina support on OS X? I have tried searching for some answers, but alas could only find a handful of posts from a few years back. Any help much appreciated! Mark -- View this message in context: http://forum.world.st/Retina-support-in-Pharo-tp4895245.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Hi, I'm getting this error while trying to prototype some interface with Spec on Moose 6.0: MessageNotUnderstood: ToolDockingBarMorph>>popUpOwner it happens anytime that I'm using displaying a MenuModel and I go to the menu items. I imagine that the menu item is complaining about a lacking pop up message. How can I solve this? Thanks, Offray

#ast vs. #parseTree
by Sean P. DeNigris May 9, 2018

Why does CompiledMethod understand both? They are in the same protocol, produce the same kindOf result, and neither has a method comment! :/ (Pharo 4.0) ----- Cheers, Sean -- View this message in context: http://forum.world.st/ast-vs-parseTree-tp4893074.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

About validation
by StÃ©phane Ducasse March 11, 2018

March 11, 2018

Hi I read the chapter on validation of the mentoring course book of andres valloud. http://www.lulu.com/fr/fr/shop/andres-valloud/a-mentoring-course-on-smallta… And I love this extension of SUnit. I loved the idea when I saw it for the first time at Lugano (presentation of Leandro Caniglia). I encourage everybody to read it. Now does anybody implemented in Pharo the SUnit extension? I would like to play with it and eventually write a chapter on it for the next book. The idea is so good. Stef

A Suggested Promotion
by Richard Eng Jan. 1, 2017

Jan. 1, 2017

I have a suggestion for future Smalltalk advocates... The advent of Pi Zero last month is an interesting opportunity. This is a very, very cheap Raspberry Pi. Anyone can afford it. I'm thinking of kids, in particular. What if we could get kids to delve into Squeak or Pharo (Squeak is better optimized for Raspberry Pi) via the Pi Zero? A competition could be set up in various countries, such as Canada, Britain, Australia, Japan, etc., where the best student submission for a Smalltalk-based Pi Zero application would win a small scholarship prize (say, $500). A panel of judges in each country would decide the winner. The contest would be much less ambitious than my now-defunct Canadian Smalltalk Competition <https://www.kickstarter.com/projects/1520902870/canadian-smalltalk-competit…> (CSC). Less control (no real need to prevent cheating). Easier to raise the prize money. The nice thing is that it would be a multi-national promotion (it's tough getting a national school competition like CSC going in other countries). Of course, because it's less ambitious, we can expect to reach fewer kids. Instead of thousands, probably more like hundreds. I could be totally wrong on this; I could be totally surprised! I might even come out of retirement <https://medium.com/@richardeng/today-is-the-first-anniversary-of-smalltalk-…> to offer some creative services (eg, promotional graphics, websites, etc.). ð Anyway, it was just an interesting thought I had. Don't know if it stands up to scrutiny. Cheers, Richard

Re: [Pharo-users] Image freezes on Linux if it was previously saved on Windows
by Nicolai Hess Nov. 10, 2016

Nov. 10, 2016

Hm, I don't know what exactly happens. It seems this behavior started with Pharo 50574. Since that image version, the UUIDGenerator will be reset on startup. Maybe the initialization of the uuidgenerator (or the random seed) will access the filesystem and at this step the file system initialization traps into an infinit loop. What I don't understand is, why this only happens when the image was saved on a windows platform and reopened on a unix platform. Maybe, saving the image (or the shutDownList) does not fully cleanup the platform settings.
