Hello, Are there any machine learning tools or libraries available or portable to Pharo? I am not knowledgeable about the field and am just learning and exploring. Any pointers greatly appreciated. Thanks. Jimmie

I think the company was aquired. If I remember correctly by Esmertec. They did Java VMs for cellphones (they came orginally from the Oberon community, I think). Esmertec quickly decided to focus on Java for cellphonez and everything Resilient was shelved. Esmertec itself merged with a french company and is now Myriad Group: http://www.myriadgroup.com/ And all the people involved went to Google to do V8 JavaScript and (I guess) now Dart.

[Pharo-project] Help with RPackage and FuelPackageLoader

by Mariano Martinez Peck

Hi guys. I have spent several hours trying to find a problem with Fuel and RPackage and I couldn't. We have a test where we create a package, we create a class and we compiled some methods. Then we serialize the package, we remove it, and then we materialize it. In a clean Pharo 1.4 image this works PERFECT. No problem. Now, if I run it in the Nautilus image (where RPackage is loaded) I have lots of problems. I am completly lost of what is happening. But it is reproducible. So I really appreaciate any help. To reproduce: 1) Take a Nautilus image from: https://ci.lille.inria.fr/pharo/view/Nautilus/job/Nautilus-Release/ 2) Install Fuel: Gofer it url: 'http://ss3.gemstone.com/ss/Fuel'; package: 'ConfigurationOfFuel'; load. (ConfigurationOfFuel project version: #bleedingEdge) load: 'DevelopmentGroup'. 3) Open a TestRunner and just run the test class FLPackageLoaderTest. Once that finish, you will have like 20 debuggers opened. In addition, like 4 error test. Without Nautilus I have only ONE red test and no debuggers. The debuggers are all in the line: self flag: 'should not arrive there now'. self halt. from CompiledMethod >> packageFromOrganizer: Thanks for any help, -- Mariano http://marianopeck.wordpress.com

As you indicate, it is not just the shortcut that changed, but a feature was removed. There used to be a way to cycle through submorphs in either direction, but now only (in my experience) the less useful direction is available. I would be happy to turn the above mentioned hack into a setting so we can all get what we want. I didn't do it earlier because it seemed like a slightly contentious issue and I didn't know if it would be integrated. Steph, would you be happy integrating such a feature? If so, I can have it ready quickly and bring back needed (at least for Edgar and I) functionality, turned off by default, so there would be no difference felt for those that don't want it...
