Executive Programming

by Ben Coman

This article about the "Mining Industry's Impending Digital Metamorphosis" https://medium.com/@CORE_Innovation/minings-impending-metamorphosis-155d668… is a little off topic, except where it says "All levels, including management and executives will need to have some level coding experience and understanding." made me think this must be pervasive across many industries and that an interesting strategy for Pharo would be teaching a course called... "Executive Programming". Pharo could be ideally suited to filling this niche... * Executives don't need to learn the *most* efficient language (i.e. C), * and don't need to learn a system suited to large groups of developers (i.e. Java) * and don't have the time to wait for things to compile (i.e. big tick immediate feedback) They are never going to "do the work" but just need to gain a general understanding of "programming" to better strategise at a higher level and interact with developers. What better language is there for this than Pharo? But guess what happens when the boss is familiar with and likes one particular language... ? /cue maniacal laugh cheers -ben P.S. I'd be interested in collaborating on something that is not an end user book, but more of an Instructors manual for such a course.

Grafoscopio Questions

by Sean P. DeNigris

I just loaded 1.3.9 into Pharo 6.1 latest (IIRC 540). Two questions: - I got an error on load about updating the docs. Is this known? If not, I'll go back and get more details - How does one contribute to the docs? I found a typo, but if I edit the STON file the PDF will not be in sync and also where/how do I upload? ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html

When there is a new version of Pharo 6.1, how can I make the launcher know about it?

call for help: answer on HN :)

by Esteban Lorenzano

Hi, yesterday someone posted an article on HN about the Pharo MOOC and there has been some negative posts there. I would like to call people who can have the time to answer there and help to explain better and also contribute to contest that FUD someones (we know who they areâ¦ sames as always) are spreading. here the link : https://news.ycombinator.com/item?id=16754872 <https://news.ycombinator.com/item?id=16754872> (this is not loosing time, people searching for Pharo will likely see this kind of messagesâ¦ at least we need to offer our point of view) cheers!

Re: [Pharo-dev] Idea and proof of concept: Accept for Test

you should use that as an example in the reflectivity paper.
