GSoC Proposals as result of the 8th local Data Week

by Offray Vladimir Luna CÃ¡rdenas

Hi, We made another data week (the 8th one), this time focused on introducing novices to Pharo and Grafoscopio to participate in the GSoC and now we have two proposals: * http://mutabit.com/repos.fossil/grafoscopio/doc/tip/Events/GSOC/2017-offray… * http://mutabit.com/repos.fossil/grafoscopio/doc/tip/Events/GSOC/2017-offray… both are related with Grafoscopio, but deal with different approaches (I thought that a project could have several students). Hopefully both can do it or the students will be able to pivot on the community binding month to other projects. Any comments are welcomed. GSoC can be an important catalyst for community building around Pharo. For example, now we are connecting better, the people that is interested with reproducible research and literate computing with ones that are interested the infrastructures that made them possible. Cheers, Offray

I often wonder why there isn't anyone on this list who has a super-tech-philantropist-that-would-love-to-help-up-engineer-pharo-further acquaintance (or is one). Anyone?

Re: [Pharo-users] Breaking News

by Greg Lewin

Scratch still seems to have no code-grouping abstractions like subroutines or, better, functions - isn't this a rather important part of learning to code well? Having loop facilities with no GOTO in sight is a good start, but it looks incomplete all the same - with subroutines, the concepts of factoring and re-factoring code could then be introduced early on.

Re: [Pharo-users] Breaking News

Scratch may be a good way to introduce basic programming concepts to total beginners, but it's hardly a substitute for a proper programming language like Smalltalk. How would you even begin to write a machine learning application or an ERP application using Scratch?

Ironically and this is not April's Fool joke, Scratch has been exploding in popularity https://www.tiobe.com/tiobe-index/ https://www.tiobe.com/tiobe-index/scratch/ So what Smalltalk has failed to achieve, Scratch is achieving it now even though it was made with Smalltalk. Makes sense though, many countries have been pushing coding into schools and Scratch was always a No1 choice, its just lately this push has been a lot more severe because of the severe lack of pro and amateur coders.

I did not use them much professionally, and then I didn't make the effort to check that the AST annotations would work correctly with them, so I had a tendancy to remove them. This is the first time I'm really checking that annotations work properly over those syntax extensions. The initial (1.X) version of thoses annotations were not compatibles with the AST annotations, so I had back then to hack the SmaCC 2.0.3 base to support them, without having the time to check it was done properly on the annotation level.
