Context is a Smalltalk distribution with a minimal object memory and a distributed module system. I will demonstrate distributed operation on a small local network of machines, focusing on use cases for remote team development.

Progress made in squeak the past year and a look at the development of spur, the new VM.

Latest developments in Squeak, changes from 4.3 to 4.4. and beyond

The Smalltalk and Unix communities are remarkable for their pursuit of continuity, each with their own mantras. "Everything is an object sending messages!" says one. "Everything is a file streaming bytes!" says the other. In the space between, on today's net, one might argue that everything is HTTP messages. Now that there is widespread support for web services like DAV, any network-capable device can appear to be a filesystem, while maintaining its own organizational metaphors and behavior. I call these "active filesystems". While they draw upon common concepts, their potential in the contemporary computing envionment has greatly increased.

Smalltalk has long had mechanisms for interacting with the rest of the world. I'll present an active filesystem, Treaty, that enables the world to interact with Smalltalk.

This talk is dedicated to the memory of Andreas Raab.

Spoon? Spoon! It's a minimal object programming system derived from Squeak, with new approaches to organization, collaboration, and deployment. Spoon is the system I want for writing and distributing software. Initially, it has only that needed for a new programmer to start and extend it easily. This includes a module system, with which any Spoon system may provide code and data to others. Each module is a live object, and coordinates the direct synchronization of providing and consuming systems. The very smallest object memory snapshot I've made is 1,337 bytes long. An interesting intermediate result of this work has been "session imprinting", the transfer of compiled methods directly from one system to another as a side-effect of running them, without needing to compile source code.
