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

UK Smalltalk User Group meeting: Richard Ronteltap - SmallJS - 26 February 2025
by UK Smalltalk Feb. 26, 2025

Feb. 26, 2025

For our February 2025 presentation, Richard Ronteltap will present his SmallJS project. SmallJS ( https://small-js.org/Home/Home.html ) is a free and open source implementation of the elegant and powerful Smalltalk-80 (ST) language. It compiles to JavaScript (JS) that runs in modern browsers or in Node.js. SmallJS is file based, not image based, so you can develop in your favorite IDE. The default setup is for Visual Studio Code, with ST syntax coloring and step debugging! You code separately from the SmallJS base libraries (image) and only the parts you use are imported automatically when running your app. SmallJS is fully object oriented, so customizable on every level. For usability, ST class and method names are kept mostly equal to their familiar JS counterparts. JS libraries already encapsulated in ST are: Browsers: Document, Window, HTML elements, events, CSS, streams. Node.js: HTTP server, Express, 4 databases, files. SmallJS is mostly intended for use by JS devs that want a nicer language to work in. But it can also be used by existing ST devs that are willing to learn a new ST framework that can directly run in browsers and can seamlessly access the powerful Node.js ecosystem, without the need for bridges between overlapping frameworks. Richard ( https://github.com/FunctionPoint ) studied Computer Science at the University of Amsterdam (UvA), where he used used Smalltalk-80 to write a query optimizer for a prototype OODBMS. He currently works in IT / Software Management within the IT department of the UvA. This will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/ukstug/events/305761370/ ) to receive the meeting details. Donât forget to bring your laptop and drinks!

Fostering a respectful Pharo Community
by Esteban Lorenzano Feb. 20, 2025

Feb. 20, 2025

Hello, Pharo is more than just a programming language and a development environmentâit is, above all, a community. As a community, we uphold certain values that form the foundation of our interactions, both technical and non-technical. We believe in human rights and the right of all individuals to live and grow in an environment that respects them, regardless of their choices. With that in mind, we adhere to the principle of the paradox of tolerance: while we welcome open discussions, we do not support intolerance, hate speech, or any attempts to introduce such attitudes into our community. We recognize that we are not just programmers but multidimensional social individuals, and discussions may (and must) sometimes extend beyond strictly technical topics. However, we expect these conversations to remain within the respectful boundaries that ensure a welcoming space for everyone. In this sense, we want to apologize to anyone that may have feel discomfort or concern by the previous discussion. Our goal is to foster an inclusive and supportive environment where all members feel safe and valued. Thank you for your understanding and for being part of Pharo. Esteban, on behalf of the Pharo Board

Pharo Association 2024 Review
by tesonep＠gmail.com Feb. 5, 2025

Feb. 5, 2025

Dear Pharo Association members, Pharoers and Smalltalkers from all over the world We are writing you to thank you again for your support of the Pharo Association. With your help, we are able to perform a lot of activities to increase the impact of Pharo, enlarge its community and have a better programming life for everyone. For the people who are not members of the association, we take the opportunity to tell you all the accomplishments of the association last year and invite you to participate in any of the forms our association provides. We want to profit this time of the year to tell you the most important actions that the association has supported the last years. - *Infrastructure for Pharo: *as an association, we support the maintenance of the infrastructure used by Pharo. We provided the funds for the hosting of Pharo services (website, file server, mailing lists) and domains. Most of the services that we daily use are supported by your help. Thanks for allowing the community to use the Pharo Launcher or getting an image from ZeroConf. - *Conference Sponsoring:* we all love to go to nice conferences and much more if there is Pharo-related content on it. This year as it is tradition we supported the *ESUG 2024 *conference. Having a place to interchange and to publish all the advances in Pharo is key to its development. - *Summer School: *With the objective of extending the Pharo community, in 2024, we sponsored a summer school at Split, Croatia about advanced object-oriented design with Pharo. Due to the nice reception and results, this year we are again sponsoring a summer school in February at Montpellier. - *Pharo Music: *Smalltalk has been always a language close to the arts, and Pharo is not an exception. This year, we heavily sponsored the development of Phausto, Coypu and CoypuIDE. *Phausto <https://github.com/lucretiomsp/phausto>* is a library and API that allows to use the FAUST compiler and its libraries (Functional Audio Stream) inside Pharo. *Coypu <https://github.com/lucretiomsp/Coypu>* is a package with methods and classes for Pharo designed for programming music on-the-fly, and it has its *IDE <https://github.com/pharo-graphics/CoypuIDE>* developed in Bloc. This tools has been presented in numerous technical and musical conferences, and in all of them they have generated a lot of attention and interest. We are much than happy with the results we are obtaining. - *Student Sponsoring:* we sponsored the access of students using Pharo to Summer Schools and visits to labs. We sponsored also the food and drinks of small meetings where students can learn and play with Pharo. This sponsoring is particularly important because often the labs are not allowed to pay trips of students, limiting the access to international students. Because of that, we sponsored students from Argentina (2), Serbia, Madagascar (3), Chile, and Bolivia. Without your support we would not be able to plant Pharo seeds all over the world. Your help is base to increase the community and to help all the people interested in Pharo. - *Book Sponsoring: *During last year, we have sponsored the write of 4 new books about Pharo. These books covers subjects for newcomers and experts, going from the style of code, testing and UI creation. All the books are available to the community (*https://books.pharo.org/ <https://books.pharo.org/>*) and even you can get a physical copy. We consider that we need to provide the material to let all the people interested to grow in their Pharo experience. We want to thank you again for your support as all the support we are getting are from our members. We remember you that you can renew or increase your subscription at *https://association.pharo.org <https://association.pharo.org/>*. Your support is really important for us because it enables us to do actions that would be almost impossible to do. Finally we remember you that we are always open to listen your opinions and suggestions, and to receive requests for sponsoring or support at *association(a)pharo.org <association(a)pharo.org>*. Sorry if you have got this mails from different channels. Thank you so much again, and we desired you and excellent new year! *Pharo Association*
