Japanese language exercises aimed at school children but also great for non-native learners like me. For me it didn't work in Firefox, which is my preferred browser, but this could possibly be because of my paranoid privacy-enhancing browser extensions.

In which I build WindEmu, an emulator for the Psion Series 5mx (a PDA from 1999 running EPOC - the OS that would become Symbian), over the course of just over a week, without access to the actual hardware. Yet another cursed project.

Axiom is an extremely flexible node-based realtime audio synthesizer. It was originally designed for size-constrained environments such as PC intros in the demoscene, but is entirely open source and is becoming an excellent free tool for any musician.

Features:

• Musician-friendly (ie knobs and sliders) interface
• Highly customizable and flexible through a node editor and custom scripting language, named Maxim
• Export to replayer with no dependencies (not even the standard library)
• Use any DAW with VSTi support for note editing and automation

WireMock is a simulator for HTTP-based APIs. Some might consider it a service virtualization tool or a mock server.

It enables you to stay productive when an API you depend on doesn't exist or isn't complete. It supports testing of edge cases and failure modes that the real API won't reliably produce. And because it's fast it can reduce your build time from hours down to minutes.
