Wow. Very nice, well done. Any chance on some more technical details, as in what 'connected by a message queue for the communication' exactly means ?

[ANN] Success story Mobility Map

by Norbert Hartl

As presented on ESUG here is the brief description of one of our current projects. Mobility Map ââââââ Mobility Map is a broker for mobility services. It offers multi-modal routing search enabling users to find the best travel options between locations. Travel options include car sharing, bikes, trains, busses etc. Rented cars can be offered for ride sharing on booking time letting other people find it to participate in the ride. Single travel options are combined in travel plans that can be booked and managed in a very easy way. For this project main requirements were scalability to serve a large user base and flexibility to add more additional providers to the broker. The application has been realized using web technologies for the frontend and pharo for the backend. Using a microservice architecture combined with a broker it is easy to extend the platform with additional brokers. Deployment is done using docker swarm for distributing dozens of pharo images among multiple server machines connected by a message queue for the communication. Pharo supported that scenario very well enabling us the meet the requirements with less effort. Pharo turned out to be a perfect fit to develop the application in a agile way. Small development cycles with continuous integration and continuous delivery enables fast turnarounds for the customers to validate progress. This is a screenshot of the search page for multi-modal results:

Okay may be it is. I guess I need to see more of it then. I played a bit with the tutorial, and I felt it to beÂ too geeky for my targeted users (teacher and mid hight school learner).

Re: [Pharo-users] MIDI IO

by Dimitris Chloupis

There is PharoSound package from the catalog browser that I see it has some MIDI capabilities but I do not know if it will work for you. I have used Pharo Sound to playback audio files but never for MIDI. As Guillermo said, UFFI is your best bet. Of course first you need to find out how its done in C depending on which library you use. I have done something like this but not in Pharo but Python. I own an Andromeda A6 , probably the most powerful pure analogue non modular synth of all time and even though it has thousands of parameters one can control via its 72 knobs and lcd interface it lacks multi point envelopes. So I made this app in Python using PyGame that I could draw multi point envelopes and the software would play them back as soon as I played a note. https://www.youtube.com/watch?v=4_DQWpViYEU Excuse the crappy GUI it was a very early draft but it worked none the less to my surprise although MIDI proved too slow to allow for quick envelops of rapid changes. So I had to abandon the project and move on. That was back in 2010 , before I started using Pharo or became aware of the existence of Smalltalk. https://github.com/kilon/vriareon On Fri, Sep 21, 2018 at 2:34 PM Manuel Leuenberger <leuenberger(a)inf.unibe.ch> wrote: > Hi, > > I am currently investigating how to work with audio in Pharo, especially > how to hook up Pharo to my synths or DAW using MIDI.

I know about GTDocumenter but this is not what I am looking for. I am looking at the idea of an infinite roll with text, code and morph. Hilaire Le 21/09/2018 Ã 18:29, serge.stinckwich(a)gmail.com a Ã©critÂ : > You should have a look to GTDocumenter. -- Dr. Geo http://drgeo.eu

Re: [Pharo-users] Pharo and fileout folder

by Hilaire

On P7, the path is hardcoded to the image directory: CodeExporter class>>writeSourceCodeFrom: aStream baseName: baseName isSt: stOrCsFlag Â Â Â | extension targetFile | Â Â Â extension := stOrCsFlag ifTrue: ['st']Â ifFalse: ['cs']. Â Â Â targetFile := FileLocator imageDirectory / baseName asFileName, extension. Â Â Â self writeSourceCodeFrom: aStream toFileReference: targetFile But there are likely other classes doing the same things differently as you seem to be able to select the path.
