May be we can break the spell in some fashion in a community and environment like this. Time will tell. Cheers, Offray

Hi Dimitris, Goals 1 to 6 overlap with the ones Grafoscopio. Could you test it please to see if we can work together in some way or Grafoscopio could work as a foundation for your work? In that way we could break the lonely developer reality for this one.

Maxwell [1]. It was until I read it that I understood I was making the wrong comparisons. I was trying to compare Squeak to other programming languages, but the proper comparison was against Operative Systems and so what was alien and complicated became simple. Smalltalk was this blend of OS + language + IDE + DVCS + App + Docs, without all the complexity of "the everything is a file" mantra of the Unix legacy approach. In fact if you have the previous combination the complexity explodes. [1] https://open.library.ubc.ca/cIRcle/collections/ubctheses/831/items/1.0055157 In this alternative curriculum for critical code+data literacy, starting with history instead of (dumb) "hello world"[2] is very appreciated and a different connection point for several disciplines: philosophy, journalism, science, activism and even programming, because once they get the idea that Smalltalk was the thing that would make alto/dynabook computers work (as Unix and its legacy is the thing that makes PC/Macs work) the new paradigm becomes less alien and the start to wonder why we have this single narrative of computing. [2] http://mutabit.com/offray/blog/en/entry/dumb-hello-world I think that is important to share this educational questions and perspectives for richer entry points to this community for programmers and non-programmers, so thanks Vitor for sparking this conversation. Here is a small capture of our mind map used to introduce the curriculum I was talking in this thread, to contrast the two traditions of computing and their mantras, Unix "everything is a file" and Dynabook/Smalltalk "everything is an object" (now the challenge is to bridge them): (The full mind map is at [3] http://mutabit.com/repos.fossil/grafoscopio/doc/tip/Docs/Es/Presentaciones/… ) Cheers, Offray

Re: [Pharo-users] The Ultimate Smalltalk Tutorial

by Dimitris Chloupis

I decided to make a new version for ProfStef released under then name "Pharo Live Tutorial". My goals are to: 1) add to it a history panel, so the user can navigate to the part he wants. 2) group parts into chapters to make progress more clear 3) break some parts to smaller parts to ensure smooth learning curve 4) add it to the help section of the world menu , so it is far more visible to the user 5) link parts to relevant chapter and section of PBE5 (or any other relevant book), so the user can easily access more detailed info in case he wants to. 6) Design the tool so it can accommodate multiple tutorials, each having its own chapters and parts 7) Design a GUI to navigate to tutorials 8) Integrate it with GTSpotter so the user can easily find the information he or she wants 9) Integrate small challenge games to help the user test what he learned and have fun at the same time, with ability to be awarded with a score in terms of "levels" and of course badges for achievements ;) 10) Provide an integrated blog (nothing fancy, just text) , for latest news about pharo , this blog will be basically copying some of my blog posts , to show to users that we are alive and kicking and not just an almost dead project and of course advertise the hard work of many of my fellow guardians of the light. PS: obviously references to Stef will remain and he will be credited as author of the tutorial Can't promise when it will be ready and can't promise first version will include all the above but this is the direction I want to go with this. This live interactive tutorial will replace my video tutorials since they are too hard to keep updated.

My opinion was in the lines of improving Profstef :) Mooc may be good in a class with a teacher for the student to take doubts, but I find a little confusing for someone that finds it by its own in pharo.org. I have some friends on the field, some are overseas (I am in Brazil) and when the opportunity comes I talk about Smalltalk and Pharo and how good it is, then: 1- Some get interested and asks for reference, I usually point to the Proftef, the site and the PBE; 2- Some are interested and we are close so I can I explain something myself and show the environment, maybe pairing; 3- Sometimes someone got interested and went to the pharo.org by itself and I know of that only afterwards. In every situation people got confused :( The best time was 2, because I could explain better what was going on, but usually people try by itself, and that don't went well. For example, some report to me that had made the exercise from PBE and got really confused in the end: what was that I was doing? Where are my classes again? Workspace? Where is the code again? What happened? I think it is hard for someone that already internalize the concept of image and self contained environment to understand why this confusion is happening, but when you come to think about it that is not so strange because people are used to files and all those crap static stuff, so it is kind of a huge paradigm shift learning Pharo: it *is* confusing for them. But it seems to me that you are focusing more on fresh people, been teach on classrooms and such, right now. That may be good, I am not sure if people already in the industry can be cooped in enough size to be able to improve Pharo community and use.

I would suggest to look at ZTimestamp https://github.com/svenvc/docs/blob/master/neo/ztimestamp.md. Maybe it is not exactly what you want.
