Hi Juan, Thanks for the great feedback!! Vector engine plugin works in JS, and the do-it error on android was solved!! Also you can see the halos in Android. Rotating a window is possible in both projects. Best!!

Smalltalk on Android and in the Browser

Hi, I'd like to share two projects related to Squeak, Cuis, and Pharo. The first is a fork of the SqueakJS project, which lets you run the latest versions of Pharo, Squeak, and Cuis, and includes performance and UX improvements. smalltalkjsvm.com.ar The second is a version of OpenSmalltalk for Android where you can run Squeak and Cuis. It was developed with help from FAST.org.ar. https://github.com/agustincico/opensmalltalk-android All feedback is welcome. There's always room for improvement. Best regards, Agustín

Looking for my next Smalltalk opportunity
by Sebastian Jordan Aug. 5, 2026

Aug. 5, 2026

Hi everyone, After almost seven years being part of the Pharo community, I wanted to reach out here because this community has been an important part of my professional journey. I am currently finishing my PhD at INRIA, France, and I am looking for my next opportunity as a software developer. After completing my PhD, I will be moving back to LATAM, Bolivia, and I am looking for a fully remote position starting around mid-October or November. I would love to continue working with Smalltalk. Most of my experience is with Pharo, but I am open to any Smalltalk dialect and different kinds of projects. I am also open to full-time positions, contracts, or consulting work. Over the years, I have contributed to several parts of the Pharo ecosystem. Before my PhD, I worked as an R&D software engineer at INRIA on Pharo, where I developed tools for code analysis and transformation, contributed to Moose and pharo-ai. I have mentored students through Google Summer of Code since 2021. I have continued to work on programming languages and developer tools throughout my PhD, focusing on runtime-related issues, instrumentation, profiling (dynamic analysis), and memory analysis. Solving difficult problems, designing clear object-oriented systems, writing tests, improving existing codebases through refactoring, and building tools that increase developer productivity are all aspects of software development that I enjoy. I also enjoy working on enterprise applications where maintainability and good design are important. If you know of a team looking for someone with my background, or if you would simply like to discuss possible opportunities, I would be very happy to hear from you. I can also send my CV privately to anyone interested. Thanks everyone for your help, and I hope to continue being part of the Smalltalk community. Best regards, Sebastian JORDAN MONTAÑO

OpenAPI now validates and tracks JSONSchema master
by Norbert Hartl Aug. 1, 2026

Aug. 1, 2026

Hi all, OpenAPI (https://github.com/zweidenker/OpenAPI) got the same treatment as JSONSchema recently: the baseline dropped its stale 2020-era JSONSchema pin and now tracks JSONSchema's master, and the library actually validates whole documents now instead of just parsing them. What's new: OADocumentValidator checks a full document against the official OAI 3.0 meta-schema (bundled, Apache-2.0), with real error messages, not just true/false. Verified against six real OpenAPI 3.0 documents from the official spec repo (petstore, petstore-expanded, api-with-examples, callback-example, link-example, uspto) - round-tripping them surfaced and fixed several real bugs that hand-written test documents never would have. OpenAPI-Client was exercised against a real spec (Stripe's) end-to-end, which is what it took to find that request bodies were JSON-only when most real APIs use form-urlencoded bodies. That's fixed too. Scope is still explicitly OpenAPI 3.0. 3.1/3.2 use a different schema dialect (JSON Schema 2020-12 + OAS vocabulary - $dynamicRef, $ref-with-siblings, unevaluated*), which needs machinery JSONSchema doesn't have yet. Not pursuing that for now is a deliberate decision, not an oversight. Code and README (installation, quick start, what's not supported) are on GitHub: https://github.com/zweidenker/OpenAPI Norbert
