Hi Everyone, As far as I can tell, JPEGReadWriter in Pharo 7 doesn't read (or write) the image metadata, e.g. title, keywords, exposure time, etc. Is anyone aware of a package that does? Thanks! Alistair

Seems that Pharo is a magnet for this kind of project. I've been writing one as well and using it to organize my research notes. Does anyone working on personal info mgmt tools want to talk offline? I expect we're running into some of the same issues, both conceptual and technical. Evan

WebDav and CalDav in Pharo ?
by CÃ©drick BÃ©ler April 13, 2022

April 13, 2022

Hi all, I do some experiments with iCal. For now I serve a full calendar over HTTP. Not bad, but it is read only. Iâd like to try CalDAV. I was looking for it, and also webDAV. Gofer it smalltalkhubUser: 'UdoSchneider' project: 'FileSystemNetwork'; configuration; load. #ConfigurationOfFileSystemNetwork asClass project stableVersion load: 'Webdav' Iâve found the project of Udo, but it doesnât load on P8. I think this is due to the stream refactoring. Right now the image hung. Iâll try maybe to load it manually. But I was wondering oof there were other alternatives ? TIA, CÃ©drick

(sorry for redundancies) Hello, Bonjour, Hola, We are looking for a Master internship to work on Cormas, a simulation platform (https://github.com/cormas/cormas , or see here for our presentation at ESUG: https://hackmd.iscpif.fr/GGwvzBFqRASE5zCzlRwArQ?view) Nous recherchons un stagiaire de Master pour travailler sur Cormas, une plateforme de simulation (https://github.com/cormas/cormas , cf. notre prÃ©sentation Ã ESUG: https://hackmd.iscpif.fr/GGwvzBFqRASE5zCzlRwArQ?view) Estamos buscando un estudiante de MaestrÃa para trabajar en Cormas. Voici l'annonce en franÃ§ais (in English below) : https://www.hdigitag.fr/fr/les-offres-de-stage-digitag/ *Simulation participative de la gestion des ressources renouvelables dans des environnements hybrides* *Mots-clÃ©*: Simulation participative, Computer Vision , Smalltalk, Cormas * *DurÃ©e souhaitÃ©e du stageÂ (nombre de mois):*8 * *Date de dÃ©but du stage*: 1/02/2021 * *UnitÃ© de recherche*: Green, Cirad * *Contact*: Bommel Pierre : bommel(a)cirad.fr * *#DigitAg*: Axe 2 : Innovations en agriculture numÃ©rique, Axe 6 : ModÃ©lisation et simulation (systÃ¨mes de production agricole) / Challenge 1 :Â Le challenge agroÃ©cologique, Challenge 2 :Â Le phÃ©notypage rapide, Challenge 6 :Â La gestion des territoires agricoles, Challenge 7 :Â IntÃ©gration de lâagriculture dans les chaÃ®nes de valeur, Challenge 8 : DÃ©veloppement agricole au Sud Lâambition dâÃ©liminer les interfaces physiques qui permettent lâinteraction avec les machines est une idÃ©e ancienne dans le monde de lâinformatique qui a pris plusieurs directions. La plus emblÃ©matique pour le grand public a Ã©mergÃ© en 2005 sous le nom de âprojet Natalâ repris et dÃ©mocratisÃ© par Microsoft dans sa derniÃ¨re version baptisÃ©e âAzure Kinectâ (2019). Ce capteur dÃ©tecte les mouvements et les objets dans le champ de vision de lâutilisateur pour produire des rÃ©sultats dans un logiciel. Il a Ã©tÃ© abondamment dÃ©tournÃ© et enrichi depuis ses dÃ©buts grand public pour permettre de nouvelles maniÃ¨res dâinteragir avec les machines. Par ailleurs, le groupe de chercheurs Ã lâorigine de la crÃ©ation dâune plateforme de modÃ©lisation Ã base dâagents baptisÃ©e Cormas [1] fait actuellement face Ã des besoins accrus dâinteractivitÃ©s dans les simulations participatives. BasÃ©e sur le langage Smalltalk, Cormas est dÃ©veloppÃ©e depuis la fin des annÃ©es 1990 par une Ã©quipe fortement interdisciplinaire. Au-delÃ des usages traditionnels de la modÃ©lisation agents, Cormas se dÃ©marque des autres plateformes par des processus originaux de modÃ©lisation : lâapproche ComMod (pour Companion Modeling : modÃ©lisation dâaccompagnement [2]), qui vise Ã proposer des outils permettant de participer activement Ã la conception dâun modÃ¨le, mais aussi de sâimmerger dans des situations de jeux interactifs. Le jeu (de plateau ou informatisÃ©) sert alors de support pour Ã©changer sur une situation vÃ©cue. En 2012, pour la premiÃ¨re fois, lâÃ©quipe utilisait un video-projecteur Ã ultra-courte focale pour projeter sur une table un plateau de jeu. Ce simple changement a induit des comportements radicalement diffÃ©rents leur permettant une interaction beaucoup plus naturelle avec les simulations informatisÃ©es. En outre, la configuration spatiale des acteurs favorise les interactions sociales. Mais jusquâÃ aujourdâhui, la saisie manuelle par lâanimateur des dÃ©cisions prises par les joueurs reste nÃ©cessaire ce qui rÃ©duit la fluiditÃ© et la spontanÃ©itÃ© des interactions. LâÃ©quipe en charge du dÃ©veloppement de Cormas souhaite investiguer les possibilitÃ©s offertes par les nouvelles applications liÃ©es Ã la dÃ©tection dâobjets et de mouvements en portant un prototype de simulation participative dans le champ de la simulation hybride entre modÃ¨le informatique et jeu physique. Ce travail de preuve de concept appliquÃ© au modÃ¨le ReHab (modÃ¨le Ã©cole de ComMod) nÃ©cessitera de mettre au point des mÃ©thodes de dÃ©tection fiables dâobjets physiques pour Ãªtre intÃ©grÃ©es dans le calcul du nouvel Ã©tat simulÃ©. Aujourdâhui, Cormas sâappuie sur Pharo (Smalltalk open-source). Cette solution est dÃ©veloppÃ©e par lâINRIA et par un consortium de chercheurs et dâindustriels. La communautÃ© dynamique propose un ensemble de packages permettant de mutualiser le dÃ©veloppement de fonctionnalitÃ©s qui pourraient Ãªtre mobilisÃ©es pour proposer un prototype pour des simulation participative et la dÃ©tection dâobjets *English* : https://www.hdigitag.fr/en/digitag-master2-internship-offers/ *Participatory simulation of renewable resource management in hybrid environments* * *Keywords*: Participatory simulation, Computer Vision , Smalltalk, Cormas * *Duration*: 8 months * *Desired start date*: 1/02/2021 * *Research Unit*: Green, Cirad * *Contact*: Bommel Pierre â bommel(a)cirad.fr * *#DigitAg*: Axe 2,Axe 6 â Challenge 1,Challenge 2 ,Challenge 6 ,Challenge 7, Challenge 8 The ambition to remove the physical interfaces that allow interactions with computers is an old idea in the IT world that took several directions. The most emblematic one for the general public emerged in 2005 under the name of âProject Natalâ taken up and democratized by Microsoft in its latest version called âAzure Kinectâ (2019). This sensor detects movements and objects in the userâs field of vision to produce results in softwares.Â It has been abundantly diverted and enriched since its beginnings for the general public to allow new ways of interacting with computers. In addition, the group of researchers behind the development of an agent-based modeling platform called Cormas [1] is currently facing increased needs for interactivity in participatory simulations. Based on the Smalltalk language, Cormas has been developed since the late 1990s by a highly interdisciplinary team. Beyond the traditional uses of agent modeling, Cormas differs from other platforms by innovative modeling processes: the ComMod approach (Companion Modeling [2]), which aims to provide tools to actively participate in the design of a model, but also to immerse oneself in interactive game situations.Â The game (board or computer game) is then used as a support to exchange on a real-life situation. In 2012, for the first time, the team used an ultra-short focal projector to project a game board on a table. This simple change induced radically different behaviors of the actors allowing them to interact more naturally with computer simulations. In addition, the spatial configuration of the actors favors social interactions.Â But until today, manual input by the facilitator of the decisions taken by the players remains necessary, which reduces the fluidity and spontaneity of interactions. The team in charge of Cormasâ development wishes to investigate the possibilities offered by new opportunities related to the detection of objects and movements by bringing a prototype of participatory simulation in the field of hybrid simulation between computer model and physical game.This proof of concept work applied to the ReHab model (ComModâs school model) will require the development of reliable detection methods for physical objects to be integrated into the calculation of the new simulated state. Today, Cormas relies on Pharo (an open-source Smalltalk).Â This solution is implemented by INRIA and a consortium of researchers and industrialists. The dynamic community proposes a set of packages allowing to mutualize the development of functionalities that could be mobilized to propose a prototype for participative simulation and object detection

Preserve VCS history while renaming package
by Vitor Medina Cruz Aug. 1, 2021

Aug. 1, 2021

Hello, Is it possible to rename a package while keeping code history? When I do that, for example, rename from A to B, Iceberg shows me that A is no longer loaded, it is not aware of the refactoring. If I remove A and add package B and prompts a commit, it shows me like all inside B is new and that A was deleted, losing the renaming history link. Is it possible to keep that link, and workaround or such thing, or for now it isn't supported? Thanks, Vitor

Hi Torsten, Further ... I just saw that SBSDevelopmentLibrary contains CSS & JS - however its for 5.0.1, Further the download library may not contain popper as mentioned in getbootstrap The JS library loaded thru html script is 5.0.2 (its in updateRoot: and renderContentOn:) If this has a bearing to carousel, collapse & modal not working then a clean up may help I tried importing the 5.0.2 JS/CSS files in a FileLibrary but it thru an error. And anyway couldn't figure out how to get popper in a library just some pointers with warm regards Sanjay Minni On Sat, 31 Jul 2021 at 12:11, Sanjay Minni <sm(a)planage.com> wrote: > Hi Torsten > > this thread / announcement is not appearing in forum.world.st, i > dont know how many in the group *_browse only_* thru that interface (must > be dwindling anyway), this is case you want to repost there thru the > browser interface there > > > with warm regards > Sanjay Minni > +91-9900-902902 > http://planage.com > https://www.linkedin.com/in/sanjayminni/ > > > > On Sat, 31 Jul 2021 at 11:55, Sanjay Minni <sm(a)planage.com> wrote: > >> Thanks, >> >> Checked it out. >> Dropdown and Navbar dropdown are working, >> but carousel, collapse and modal are not working. >> >> also, i don't know if it is relevant - >> on the bs5 doc homepage (at >> https://getbootstrap.com/docs/5.0/getting-started/introduction/) : >> 1. it says css file >> https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css >> must be loaded before other stylesheets, but i couldn't see it loaded. >> 2.
