This post describes technology and support for using an XML schema in a Python application.

This post describes an HTTP REST application built to be served by the Erlang Cowboy Web server. The application's development is managed by rebar3. A template or skeleton for creating the Cowboy REST handler module is also discussed.

This post describes software that can be used to implement HTTP REST applications that can run on the Raspberry Pi under Raspbian Linux (and other Linux variants, too). We also discuss how to install and configure that software, and how to use flask and flask-restful to implement REST API and REST applications.

This post discusses the implementation of and FSM (finite state machine) in Erlang with the gen_statem module. In this implementation we enable the server/FSM to carry some internal state whose value is different for each of multiple instances of the server process.

This post discusses the implementation of and FSM (finite state machine) in Erlang with the gen_statem module. We emphasize the implementation of the FSM by creating a table of rules that define the transitions (from state to state) of the FSM and then implementing the FSM by translating those rules into code (in this case, Erlang code).
