Nov 22: Michael Lucas-Smith on Xtreams

In order to welcome Michael Lucas-Smith and Helge Nowak, who will be visiting London this month, we've moved our November monthly meeting one week earlier to Monday, November 22. Michael has offered to give us an in-depth presentation on Xtreams, a streaming framework with a new and refreshingly consistent API. From the project page:

Xtreams is a generalized stream/iterator framework providing [a] simple, unified API for reading from different kinds of sources and writing into different kinds of destinations (Collections, Sockets, Files, Pipes, etc). Streams themselves can be sources or destinations as well. This allows to stack streams on top of each other.

It is the stacking nature of the streams that give this framework its real power and, from what Michael and Martin (Kobetic) have shown me, you can do some pretty impressive stuff. Martin's presentation at ESUG only scratched the surface, apparently, and Michael intends to delve even deeper. There will also be plenty of time to ask him about Cairo or WebVelocity over drinks after.

We're at our usual venue and time: The Counting House (near Bank Station) at 6:30pm.

A Tour of Architectural Abstraction with Objective-S - Wednesday, November 24th

This month, the UKSTUG will take a look at Objective-S , an architecture-oriented programming language based on Smalltalk and Objective-C, by hosting his creator Marcel Weiher. As per Alan Kay, “Code seems large and complicated for what it does” . Objective-S addresses one source of this accidental complexity: using software architectural abstraction to directly expresses the much wider variety of architectural styles typical of modern software systems, compared to traditional programming languages that still follow the call/return architectural style of scientific programs from the early days of computing. Marcel Weiher started his forays into dynamic object-oriented computing by implementing Objective-C on his Amiga 35 years ago and hasn’t stopped since. Stops on the way have been at Apple, the BBC, Microsoft and various startups, as well as contributing to Squeak. He is currently a principal software engineer at Citymapper and PhD student at HPI, where he is trying to distill some

Deploying to the cloud from Pharo - Wednesday, July 29th

The next meeting of the UK Smalltalk User Group will be on Wednesday, July 29th. Peter Svensson will present his work on Cloudsdk-st. Cloudsdk-st is an experiment in ways to work with cloud deployment from a Smalltalk image. Traditionally cloud deployments run 'out of band' in separate build scripts or build/CI/CD systems. This project lets you define Docker images (using Dockerfiles) for Smalltalk, send them to the build system of a cloud provider directly and then choose what kind of service you want your image to be (cloud function or long-running VM). Currently it only supports Google Cloud and has a very rough UI. Future plans include support for AWS and Azure as well as better feedback and a Spec2 UI. Given the current COVID-19 restrictions, 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 to receive the meeting details. Don’t forget to bring your laptop and drinks!

Kyma - an object oriented sound and music system - Wednesday, May 27th
