Re: [Pharo-users] Announce: whisper updated

by Robert Withers

The code is broken, so I jumped the gun again! Its more than I thought with PBE iv problems. I rolled the code out of the Cryptography repo until I can get it straight. The vm issue can use this package to reproduce: http://jmp.sh/GWcI9rB.

Phil, Installation is reported to work on Pharo Catalog. Can you try to install it from there while I figure out what is wrong with the alternative install procedure?

Re: [Pharo-users] Announce: whisper updated

by Robert Withers

Though the whisper code is currently language inter-inoperable, the latest code is being hosted on gitlab with International Rabbits, as voix-basse-mourde. Here is the code: https://gitlab.com/des-lapins-internationale. If you would like to help, Java could be brought forwards adding PBEReader/PBEWriter, dataEncoding negotiation, SecureSessionSpecification with filtered cryptoProtocolNames, dataEncoderNames, scopeMaker and the traceDomains to parameterize the server behavior. On the Smalltalk side, Whisper_json, Whisper_magma and Whisper_fuel could be implemented. Matching JSON on the Java side. FEC Reed-Solomon could be tested and repaired (it's broken). kerkkutatti is the Java code for remote promises and has the Smalltalk porcini code too. With Whisper's new SecureServerSpecification, the injection of a scopeMaker and encoder is all the config after push into the stack. Lots of work there on both sides, to get them talking. If you want to help, have a beer and I'll match you, let me know what you want to work on and I can add you as a gitlab rabbit.

Re: [Pharo-users] The Ultimate Smalltalk Tutorial

by Dimitris Chloupis

Absolutely , I am enjoying calling the way I work "parasitic coding" mainly because I love to use/ take advantage/canibalize existing libraries, languages and applications. Grafoscopio, Pillar, existing ProfStef, Morphic , whatever can help me open a link in a web browser and anything else will be on my plate. Working together is doable too. Unfortunately I cannot load your project in Pharo 6 it complains when I use Gofer about an out of bounds problem, if I use monticello at Loading ConfigurationOfGlamourCore-PabloTesone.152 gives error about a missing quote. PRDocumentItemTest methodsFor: 'tests' stamp: 'lr 3/30Unmatched ' in string literal. -> Grafoscopio is very good and thanks for reminding me I have completely forgotten it , which means I will need to take a good look to see what else is out there I can use. GUI wise, its quite different from what I imagined for my project so at least that part I will have do , feature wise though it seems like you covered many of my goals indeed though I will give a lot more close look in a few and in the near future.

The experience confirms that Pharo and Roassal are hidden gems for a public beyond computer scientist and programmers and data driven stories and argumentation, agile visualization and interactive documentation can be the bridge for that broader public. >> Our approach in our Data Week workshop is different: >> >> - We start with some panoramic view of computing comparing Unix >> fathers versus dynabook children.

I think that Grafoscopio notebooks have this potential for tutorials on steroids, because they have this outliner interface to group lessons together (by level, by theme), as shown in the screenshot, interactive playgrounds to execute the code and explore the objects, a GUI and document format powered by STON to save changes easily (without knowing previously how to program in Pharo) and share them via mail or DVCS. Now I'm debugging the installation process. My ConfigurationOfGrafoscopio is working locally, but I have reports of problems installing them. I don't know exactly where to start the debugging, but hopefully I will have a easy to install and use interactive notebook for tutorials on steroids and personalized curriculum. >> - Then we learn how to extend the Dataviz package (made in Roassal), >> with our Twitter exported data and we deal with an open problem: >> Twitter Data Selfies. >> >> >> So, there are several routes to learning for different populations >> and contexts.
