Working with Independent Objects

The traditional way of writing and changing software has led to Continuous Deployment, a principle of automating the pipeline between writing source code and deploying the production artifact in a live environment, with a goal of reducing the time taken for changes to flow through the pipeline while maintaining a high level of quality.

Environments such as Pharo—https://pharo.org/, SqueakJS (https://squeak.js.org/run/#url=https://freudenbergs.de/bert/squeakjs&zip=[Squeak5.0-15113.zip,SqueakV50.sources.zip], or even in their limited ways Swift Playgrounds—https://www.apple.com/swift/playgrounds/ and Project Jupyter—https://jupyter.org/ show that this pipeline can be zero length, and that software can be written directly in the environment it is intended for. The result of a test failure does not need to be a log file served by Jenkins that must be pored over so a fix can be hypothesized in “local dev”, it can be an opportunity...
