Very occasionally I encounter well organized research software that can be used without having an email conversation with the author (who has…
Since the start of the year, the AWS Rust team has been drafting our charter and tenets. Charters and tenets are the framework AWS teams use to define our scope and priorities. The charter tells you what the team does, and the tenets tell you how the team will do it. Since one of our […]
