Hi Chris, I attached a screenshot of the desired result. It seems to me the problem is not where the arrow is connected, but the Tree Layout, which is positioning the "Test" label as if it would be the root of a tree with the svg figures as their leaves. I still don't get how to apply a vertical layout (not tree) to a RTCompositeShape, assuming that could be a reasonable solution.

In AWS S3 you have to set the correct mime-type when you upload a file, this can also be changed afterwards. If not, it remains binary (application/octet-stream).

Next step of my Asana adventure. In a browser https://s3.amazonaws.com/profile_photos/206785263586755.0mU1QMOxVZLp3WiRWhW… downloads a png.

I have generated a Personal Access Token, and the terminal command of: curl -H "Authorization: Bearer 12345abc" https://app.asana.com/api/1.0/users/me Returns 200/ok, and the right data. However, the pharo commands tmp1 := ZnClient new. tmp1 headerAt: 'Authorization:' put: 'Bearer 12345abc'. tmp1 url: 'https://app.asana.com/api/1.0/users/me'. tmp1 get. Results in an authorisation error. I haven't tried using Zinc to access authenticated sites before, what am I doing wrong? Cheers Andy

Actually there is a probably a configuration file, but not in the place where I checked, I assume. I have Ubuntu or Ubuntu based test installations in partitions sda6,7,8,9,10.

The idea of a bridge is an interesting one. One of the core Dynabook/Smalltalk principles is that the whole computer should be available for inspection and experimentation by the user. As Dan Ingalls said about operating systems "there shouldn't be one". However, the rest of the world is stuck in an application/stovepipe model. While that may cripple and pigeonhole users' creativity, it's a reality that to be practically and generally useful the Dynabook would now have to deal/interact effectively with that whole mess while we're waiting for the rest of the world to catch up to our better way of doing things. ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] Dynabook and authentic learning pedagogy

by Hilaire

Hi Offray, >From my understanding, the Dynabook concept is rooted to the idea of dynamic media or active essay and user engagement in producing this dynamic media contents. Etoys is a step in this direction, its innovative graphical programming environment supports the end user engagement in producing such dynamic media. I try to explain it in a previous article (http://blog.drgeo.eu/post/2018/The-Dynabook-Concept) In my opinion, Scratch is not related to this dynamic media vision. It only borrows the concept of graphical programming environment to provide an accessible environment to initiate kids to programming and algorithmic. The Dynabook concept is very rooted to the constructivism movement and its learning models, which are not that effective according to researches. I discussed a bit about that on another article (http://blog.drgeo.eu/post/2018/The-Dynabook-and-its-learning-models) Nevertheless, teachers mix different teaching approaches, so I think it is interesting to look at the dynabook concept under the different teaching models coined as innovative. I wrote several small texts about that. Authentic learning pedagogy is one of this teaching model. In your example, your authentic document is your raw data and Grafoscopio is a scaffolding tool to make this data learnable. I am just guessing because I don't know Grafoscopio. What I found interesting in your case, is the central position of the text document. Text is such a handy media: video and audio run on the air then are gone, a text stays there under your vision, it is very easy to "play it" one paragraph backward or forward. In Dynabook there is this idea of dynamic book: text with dynamic content, I love it. As a teacher I will love to be able to produce textbook with text math and dynamic simulations (geometry, calculus, algebra micro-world) for the kids to learn with. Such dynamic simulations could just be pluggable Morph components, teachers will pick up and/or adapt to specific needs, eventually linkable, Ã la Etoys, and shared on the net, etc. Hilaire -- Dr. Geo http://drgeo.eu

We have a long tradition of documentation in the Colombian FLOSS communities with an old wiki that reached, in its good times, 4000 pages (now only spread in offline backups). Most of this documentation is done using light markup languages and recently a strong tendency is in the use of variants of Markdown (mainly because of their preeminence in sites like GitHub and StackOverflow). Also we are concern with online and offline edition, because connectivity is not a given in countries of the so called Global South and because web technologies are (gratuitously?) overcomplicated. Those authentic documentation workflows and needs are the ones that Grafoscopio is trying to support. Several demos of such documentation use cases have been done, like the Data Journalism Handbook[1], blogging on reproducible research and data activism, storytelling and visualization[2][3][4] and, of course, the Grafoscopio Manual is written it itself[5] (because, you know, we love metasystems that help to evolve themselves). [1] http://mutabit.com/repos.fossil/mapeda/ [2] http://mutabit.com/offray/blog/en/entry/panama-papers-1 [3] http://mutabit.com/offray/blog/en/entry/sdv-infomed [4] http://mutabit.com/offray/blog/en/entry/ds-twitter-mockup [5] http://mutabit.com/repos.fossil/grafoscopio/uv/Docs/En/Books/Manual/manual.… This means that the Dynabook, at least currently can be (de)construct like something in between a software among many others, running in a host, but also something connecting to today's real needs, like the ones you solve in office software (word processing and documentation, calculation and visualizations, and presentation), despite not solving them in the same way (what would be the point then?). In Grafoscopio's case, the outlining metaphor (a la OrgMode[6] or Leo Editor[7]) is important is such alternative approach do documentation. [6] http://orgmode.org/ [7] http://leoeditor.com/ Which leads us to the issue of benefit? Who benefits from this other ways of authentic documentation? One of my issues with current Dynabook incarnations and research papers, in the form of Smalltalk (and its variants and projects, including Squeak, Etoys, the original Scratch and Phracth), is that they are too oriented towards children and teenagers (with incidentally teachers in the mix) or computer scientist. I felt that the more I grow up, the more frozen the "software" felt for me, because the huge gap between the intended audiences of the software (children, teens, their teachers and computer scientist) and the rest of the population. If I departed from those communities and needs, it was difficult to find any place for me in the Dynabook/Smalltalk related communities and their used tools. There was little to nothing for the day to day task (i.e. documenting) or it was too insular and departed for more widely spread practices (i.e. Markdown or Pandoc) or without the huge traction and diverse functionality of custom made formats and tools (i.e. OrgMode). It was like if, Smalltalk keeps its curse of being so concern with the future that was disconnected from most of the present and so, giving the majority of us no bridge between our present and the Dynabook vision. I think that data activism, storytelling and visualization joined with reproducible research and publishing can help us to bridge the gap mentioned before for a lot of diverse populations (journalists, activists, researchers, academics, students) that are leaving or outside the classroom or are already adults and such themes are concerns from the present and the upcoming future. That's why Grafoscopio locates in such places and educational context beyond the classroom (hackerspaces, workshops, innovation labs, newsrooms). I think that The Home Desktop System [8] is tackling other knowledge workers with a parallel similar approach, including outlining [8] [8] https://github.com/hpi-swa/Rack Grafoscopio is trying to make its contribution for authentic documentation in learning pedagogy for long life learning. Children, teens and the classroom are an important concern and also the needs of computer scientists, but, of course, they're not enough and we need to provide more bridges for empowering more diverse populations with authentic learning pedagoty. I think would be important to know what we can come with, as a community, so more people can traverse such bridges and build more. Cheers, Offray

Authentic documents are situation or media from the "real world" used in teaching situation. It can be an analog or digital document: a poster, a TV advertisement, a TV show, or it can be a real world problem. Often these ones need to be scaffolded by the teacher to make it accessible to the students. Speaking about docs/dot support, could Dynabook support it? It depends on what it will be. 1.

Hello Installing Roassal in 6.1 through the catalog gives the message that it has not been tested for installation in 6.0. See screen shot. Is this the regular way to go for or is there a better installation script? Regards Hannes

Yep. Especially if using the in-development version of Pharo (currently 7), I find it useful to pair images and VMs. > I think where snap still might come is for solutions which require > more than a particular Pharo installation. > > For example I could think of combining a particular Pharo version with > a particular Jupyter notebook installation into a snap which could > lead to a web based 'Dynabook' solution. That was one of the things that attracted me to snaps originally, I use sqlite in my daily environment, so included it in the Pharo snap. > I am also looking forward to Guille's answer. +1.

Re: [Pharo-users] How do I get ZeroMQ working?

Yes, I re-evaluated in the playground Metacello new baseline: 'JupyterTalk'; repository: 'github://jmari/JupyterTalk:master/repository'; load:'all' Then save and quit. I hope that this was sufficient. jupyter notebook create new Pharo Smalltalk notebook --> the notebook was created. Evaluate an expression --> the attached error comes up. The library is still not found. It is looking for version 3 wheras the anaconda installation has 5. At the moment for me anaconda support (600MB download) is nice to have but not necessary. The other ways of installing jupyter notebooks (pip3 and nteract, 50MB download) need less space and start giving good results. I suggest to put this as an issue at https://github.com/jmari/JupyterTalk for the moment.

Last update works also on *nteract* In the other hand, I could not understand how Jupyter knows about Pharo kernel without the configuration file!!! Unbelievable! -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
