I know that in squeak there was the project of Cees de Groot Tric on Squeaksource.I can send you the files I got.

Re: [Pharo-users] distributed peer2peer sharing app in Pharo

by Evan Donahue

Hello, Just to follow up on Juraj's reply: Trantor is a framework for distributed applications. The basic idea is that you can establish a p2p network between various images, and then build applications using a set of specialized distributed collections that can be plugged into the p2p network and synchronized between hosts. The example Todo application is just a simple spec gui that writes items to a basic distributed collection. That collection is added to a running Trantor host in the image, and changes are broadcast to peer hosts in other images. The project is in the early stages, but it's definitely ready for prototypes and personal apps. I have been using Todo to synchronize a grocery list across all of the computers in my house (computers can join and leave the network and stay in sync). If anyone thinks they may have a use case for such a framework, please do get in touch. A lot of infrastructural decisions have yet to be made, and more use cases would really help ensure the final product is as broadly useful as possible.

Renaming a Class triggers debugger

by Lyn Headley

Hello, I'm running pharo 4 and I'm having a problem. I recently renamed a class using the rename: menu item in the standard system browser (I believe it's called Nautilus) and now I am getting uncaught exceptions whenever I add or remove a method (three debugger windows pop up). Here is the stack trace; any advice? Thank you.

Re: [Pharo-users] Pharo messaging

by Paul DeBruicker

You could use the Tropo.com libaray here: http://smalltalkhub.com/#!/~pdebruic/Tropo Or the Twilio.com library here: https://github.com/newapplesho/twilio-smalltalk both let you call phones (& answer them) and have Pharo act like an interactive voice response system reading text to the call recipient and listening for verbal or key press responses. Those libraries also send SMS messages. Norbert Hartl had a system in place to send push notifications but that may have been in conjunction with his own app rather than a 3rd party platform like urban airship -- View this message in context: http://forum.world.st/Pharo-messaging-tp4855326p4855438.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

I think Pharo is the most user empowering environment I > have found. I agree with you. I share your vision of Smalltalk as the most empowering environment I have used. First time we meet (vÃa EToys, Scratch, BotsInc) I felt in love, but weren't ready for each other and took almost 10 years and Pharo to bring me back (kind of a bittersweet love story). I'm a simple user, but in this last year after returning back I have made stuff I just thought/dream about in other environments. Still a lot of things to learn and rookie code and practice, but I'm improving faster that in any other environment, despite of having not as much time to practice as I would like. Even prototyping is faster... a lot faster. I want to help Pharo too, by making it talk better with other/external ways of thinking/practicing computing. For example, after my talk with Serge about IPtyhon/Jupyter and Grafoscopio (my learning project) it was clearer to my that interactive documentation and data visualization was being bridged with objects via scripting (thanks to embedded playground in the document tree). So you can start thinking in a more "emergent way": documents and scripts instead of a hierarchy of objects and messages, and then go from your scripts in documents to more objectual forms as you clear your mind about the problem. This practice/thinking was far away ten years ago for grown ups in Etoys, BotsInc, as also happened with documentation (they happen elsewhere and not inside the image). > And yes, the other solutions do offer that as well as they are open > source.

It is home. > I know others who like the other tools, and multiplicity of choice. > And they feel comfortable there. > I prefer Pharo too. I have felt the "red pill" effect talked several times in the Pharo/Smalltalk culture. You just need to enter the matrix sometimes to awake others :-), which means that you share their reality for a while to teach them you can bend the rules or have super powers after taking the red pill. But you need to enter the matrix to offer them the red pill. My way to enter the matrix and made that offer is via interactive documentation, scripting and data visualization, because this juncture appeals a lot of people beyond programmers (like myself). The way I want to use to evade the complexities of other technologies, idiosyncrasies and cultures is try to talk only with the backend (storage formats/schemas) and frontend (these days mostly html). But I want to use what I already have and know to make that bridge. Put Pharo/Smalltalk in the existing practices and technologies in a symbiotic approach (or something like the assimilation of of star trek's cyborgs, until "resistance is futile", to follow with SciFi images :-) ). I have blogged recently about a specific case for this approach here: http://mutabit.com/offray/blog/en/entry/2015-10-06-grav-nikola-both > Choice is nice.

I performed a few tests using its REST interface with Curl, and it is pretty straightforward. It wouldn't be hard to implement a REST client directly in Pharo, as we already have for services like Mandrill. Regards! Esteban A. Maringolo
