Discussion on life logger applications (from Geolocalization apps to MicroPub) => Are people interested in porting apps from https://indieweb.org/p3k ?
by CÃ©drick BÃ©ler Dec. 15, 2018

Dec. 15, 2018

Hi all, I was looking for iOS geolocalization app on GitHub and found Overland from Aaron Parecki. https://github.com/aaronpk?tab=repositories <https://github.com/aaronpk?tab=repositories> Cool app that can send straight to a Pharo image gps points. So perfect as a basis to build a cool tool for my students and research projects... What was even more interesting is that exploring Aaron web site, I realized the guy store his digital life I an private manner like I would love for years... https://aaronparecki.com/gps/ <https://aaronparecki.com/gps/> https://aaronparecki.com/ate <https://aaronparecki.com/ate> https://aaronparecki.com/drank <https://aaronparecki.com/drank> I then found several tools I find cool and that I would like to port eventually (itâs in PHP right now) to build a life logger. I learned in the process about micropub which seems to be a good tool to post with a little semantic to a server (micro format based). https://micropub.net/draft/ <https://micropub.net/draft/> https://indieweb.org/Micropub <https://indieweb.org/Micropub> *** Do people know if we have implementations out there of the micropub/microformat tools ? *** Do you find them interesting ? Who would be interested eventually to help me port such kind of librairies (from there mostly https://indieweb.org/p3k <https://indieweb.org/p3k>) ? http://atlas.p3k.io <http://atlas.p3k.io/> https://github.com/aaronpk/Quill <https://github.com/aaronpk/Quill> https://quill.p3k.io/docs/note <https://quill.p3k.io/docs/note> https://indieweb.org/XRay <https://indieweb.org/XRay> Cheers, CÃ©drick

StCAD is open source
by askoh Dec. 15, 2018

Dec. 15, 2018

Hi: I have just open source StCAD (MIT license) which has the code for freeCAD. http://askoh.com/stcad Although written in VisualWorks Smalltalk, I hope Pharo users will port it in part or whole. All the best, Aik-Siong Koh What is 'StCAD'? 'StCAD' is a basic 3D CAD framework in Smalltalk (VisualWorks 8.x). It extends the GF/ST 2D drawing framework into 3D. It also include 'StCAD-Geo' which is the 3D geometric domain, 'StCAD-Math' which provides the mathematical support for 3D CAD and motion simulation computations, and 'StCAD-Doc' which is a simple word processor. 'StCAD-Math' is also suitable for engineering, scientific and business computing. The parcels are open source using MIT License. Users can use these parcels with other private software to create 3D applications like motion simulation, finite element analysis, CAD, scientific visualization, etc. 'StCAD' allows users to create and manipulate assemblies, which are collections of 3D parts. The parts are 3D solids, which can be connected by joints, constraints, contacts, actuators, springs, dampers or forces. The parts and connections define the structure or mechanism that the assembly is meant to represent. Animation is possible, if the user can provide time series of position and orientation data for the parts. Users can also obtain output data in the form of plots and tables. XY plots can be zoomed and set to equal scales. Data series available include linear and angular displacements, velocities, accelerations and other user generated data. 'StCAD' has been used to create a freeware called 'freeCAD' which is a 3D CAD with Motion Simulation.

Re: [Pharo-users] Agile Artificial Intelligence book
by mldavis99 Dec. 14, 2018

Dec. 14, 2018

Hi, the Book so far is great, I am looking forward to more. However, when I try to load the code with: Metacello new package: 'NeuralNetwork'; repository: 'github://AgileArtificialIntelligence/PharoSourceCode/src' ; load. Both Pharo 6.1 stable and 7 Development Version do not understand: package: When I dig into it a bit this message is implemented in an abstract method of Metacello which does not appear to be in Metacello hierarchy?? What did I miss? mike -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Is there any workaround for this problem? Regards, Vitor

Usage of String and FileLocator to reference files in ZipArchive (and probably other places)
by Hans-Martin Dec. 14, 2018

Dec. 14, 2018

Hi, I've stumbled upon a 7.0 incompatibility with regards to how file names are treated. In 6.1, I can use Strings and FileLocators interchangeably to create and read Zip archives. That's because StandardFileStream does the magic behind the screnes. In 7.0, StandardFileStream has been deprecated, and "File openForReadFileNamed:" is used instead. That method does not handle FileLocators, so code that uses FileLocators to open Zip archives ceased to work. What's the preferred solution? It strikes me as illogical that objects which were made to reference files can't be used to reference files in these contexts. However, there may be a conscious design decision behind this change that's just not obvious to me. Cheers, Hans-Martin -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Playing with Pharo 7
by Konrad Hinsen Dec. 14, 2018

Dec. 14, 2018

Hi everyone, after finishing the Pharo MOOC, I have started to play with a simple project of my own, initially using Pharo 6.1. Since Pharo 7 seems to be coming soon, I wanted to try it out, and that lead to a few practical questions. 1) How do you move your personal environment to a new image? If I have to re-do my settings and re-load one by one the packages I use, I won't be trying out new images more than strictly necessary. 2) My test project lives on GitHub, so I fired up Iceberg under Pharo 7 to load it. Works fine... but I cannot commit and push under Pharo 7. Iceberg pretends that there are no changes. With Pharo 6.1, this works very well. Has the operation of Iceberg changed significantly? If so, what would be the best place to learn about this? Any pointers would be appreciated! Cheers, Konrad.
