I have pointed to it as a reply in this thread. The upcoming data week local event will boosts some support for collaboration via Fossil SCM, SQLite integration, easy installation via Pharo Catalog and increase our gallery of data visualization approached themes/templates this time aligned with some efforts on Open Spending / Open Budget[1][2]. Our last exploration was using this tool for supporting open research in visualizing medicine public data released by governments[3] [1] https://openspending.org/ [2] http://openbudgets.eu/ [3] http://mutabit.com/offray/blog/en/entry/sdv-infomed I'll keep you informed on our advances and issues.

Imagine that instead of having a website or a book or a pdf somewhere you would have a more live version directly in the image that you could interact with. The idea of grafoscopio's[1] interactive notebook is precisely that one. Documents are trees, but instead of being represented in HTML or XML or LaTeX, they live directly inside the image and nodes in that tree have two main forms: text and code. Textual node are edited in a light markup language (pandoc's markdown) and can include references to another media (images, html embed snippets and so on) and code nodes are interactive playgrounds with all their benefits. The tree can be used to structure the writing by imposing/emerging hierarchy on it: chapters, examples, main ideas inside a text, and so on, with the use of tags that tell the tree how each node will be treated. Trees can be exported to several formats, including markdown, LaTeX, HTML and pdf (vÃa LaTeX). [1] http://mutabit.com/grafoscopio/index.en.html Because grafoscopio is also a self-learning exercise, is full of rookie code and incomplete functionality, but hopefully it will get better with my upcoming internship. It's taught and evolved mainly in a community event called data week and the next week we will start our third edition [2], so I hope also to get some boots in functionality soon and share it back with the community.

We would like the Playground to be formed of Snippets, where each Snippet can be of different types (one of them is a picture). We had indeed a prototype that was demoed at ESUG. This will have to be redone once Bloc becomes more stable. This will not be immediate, but this is an important goal for us. Nice to know! There is some intended date for this? Cheers, Offray

help needed for testing the order in spotter

by Tudor Girba

Hi, We need a bit of help with testing the order in Spotter. We do not have a real solution yet, but the current one should improve the situation. We need a bit of feedback for this one: https://pharo.fogbugz.com/f/cases/17656/Spotter-should-sort-search-results Essentially, you would need to load the latest GT-Spotter and GT-SpotterExtensions-Core and let us know if it works better for spotting implementors or classes.

Hi, Ok. Indeed, what you are describing is what we call Snippets. We would like the Playground to be formed of Snippets, where each Snippet can be of different types (one of them is a picture). We had indeed a prototype that was demoed at ESUG. This will have to be redone once Bloc becomes more stable. This will not be immediate, but this is an important goal for us.

We have been using it, some times, to help newbies in our local hackerspace workshops to install/launch particular images.
