[ANN] license selector

by HernÃ¡n Morales Durand

Hi everyone, Today I released license-selector, a little Pharo Spec based application to browse available licenses from the SPDX list (Software Package Data Exchange, an open standard now published as ISO). It is also possible to get updates for new licenses and export the license text to a file. https://github.com/hernanmd/license-selector Enjoy, HernÃ¡n

UFFI callback, getting function pointer

by tomazz.turk＠gmail.com

Dear all, I'm constructing a rudimentary webview library for Pharo with UFFI (available here [https://github.com/eftomi/Pharo-Webview](https://github.com/eftomi/Pharo-We… "https://github.com/eftomi/Pharo-Webview")). For now, the basic things work under Windows. Iâm using âa tiny cross-platform webview libraryâ available at [https://github.com/webview/webview](https://github.com/webview/webview "https://github.com/webview/webview"). One of the functions in the dll allows to register a C function to act as a callback and that can be used as a function in javascript, which is convenient for webview presenter - main program communication. This function has the signature: ``` extern void webview_bind(webview_t w, const char *name, void (*fn)(const char *seq, const char *req, void *arg), void *arg); ``` fn is the callback function. Is there any way to make a ffiCall description of this kind of signature, where fn would be an address of the callback in Pharo? Thanks and best wishes,\ Tomaz

Re: Platform studies

by Offray Vladimir Luna CÃ¡rdenas

Hi Rafael, Thanks for those provocative reading recommendations. On the use of Smalltalk or its derivations from a more sociotechnical point of view I would recommend Maxwell's Tracing the Dynabook, a study of technocultural transformations [1]: [1] https://mutabit.com/repos.fossil/indieweb/uv/docs/es/miniwiki/grafoscopedia… Also on alternative tech stacks as a way to inhabit alternative futures, recently I was presenting The Weekly Package (think in a Cuban Hulu/Netflix alike of 1 terabyte of data of media working offline across all the island) and how we mapped it by combining it with Pharo/GT, TiddlyWiki and Fossil: """ Because infrastructures organize/accumulate action and embed/transport contexts, by choosing alternative tech stacks, we are enabling ourselves to inhabit/explore alternative futures. ie by choosing techs like TiddlyWiki instead of MediaWiki, Fossil instead of Git, Pharo instead of Python, HedgeDoc instead of GooglDocs, and so on,Â and by arranging such technologies on our own stacks and workflows, we are answering ourselves, via prototyping, about alternatives to questions like: * How to organize and empower community learning and memory, particularly in places with intermittent/low connectivity and diverse (mostly small to medium) computing/storage/processing resources? * How to inhabit the continuum between online/offline, inter+personal/collective, synchronous/asynchronous, documents/data/software? * How to introduce meta-systems that enable us to change the (media/digital) systems we inhabit? """ You can find a graph of The Weekly Package art metadata below and the complete mail in [2]. [2] https://lists.riseup.net/www/arc/grafoscopio/2021-11/msg00000.html One of the things that wonders me is how context informs the development of technologies and the communities around them, which, in time, informs the presents and futures traversed by such communities-technologies tandems. In the case of Smalltalk, I have seen it deployed time and again in the context of academic, enterprise and research institutions. But in our case, as Smalltalk, Pharo, GT deploys in a hackerspace other concerns and approaches are taken, which in time mean exploring "alternalities" of technologies in the present, more related with hacktivist, civic tech and grassroots communities. (I will try to propose a talk in that sense for the upcoming ESUG or the Smalltalk 50 years in Canada).

Re: Pharo Graphs

by Sebastian Jordan Montano

Hello Serge, The plan is only to remove the graph algorithms from the Moose Algo (Moose-Algos-Graph) and to load them from the Pharo AI library instead. I saw that you reference in graph generator algos some classes of the edges. What we can do is to use the nodes from the pharo-ai library instead. But also I think that it could be interesting to move the graphs generator to pharo-ai repo. I do not know. What do you think? We can discuss it.

Great to have this library. I have implemented various random graph generation algorithms that are part now of the MooseAlgo library: [ https://github.com/moosetechnology/moosealgos | https://github.com/moosetechnology/moosealgos ] Like Albert-Barabasi algorithm and others: [ https://github.com/moosetechnology/MooseAlgos/tree/development/src/Moose-Al… | https://github.com/moosetechnology/MooseAlgos/tree/development/src/Moose-Al… ] I planned to implement new algorithms that I needed for my work. Do you plan to replace completely MooseAlgo with the new library?
