Lisp Koans is a self-guided learning path for Common Lisp that teaches the language’s idioms through a series of failing tests you progressively make pass. Each koan introduces a concept—symbols, lists, macros, multiple dispatch, reader syntax—then asks you to fill in the blanks and run the suite again. The feedback loop is intentionally tight: fail, reflect, fix, and rerun until the tests become a form of living documentation. Because koans are organized from fundamentals to metaprogramming, learners internalize not just syntax but also Lisp’s philosophy of code-as-data. ...

...The guide is designed to be skimmed during review, turning tribal knowledge into a repeatable checklist. It champions empathetic reviewing, emphasizing clarity, small diffs, and constructive feedback that helps teams move faster. By treating code review as a skill with teachable patterns, the project helps teams catch issues earlier and raise the overall bar.

...Because it is code-first, users can copy, modify, and run the examples on their own datasets, encouraging experimentation and deepening understanding.

JChart2D is a easy to use component for displaying two- dimensional traces in a coordinate system written in Java. It supports real-time (animated) charting, custom trace rendering, Multithreading, viewports, automatic scaling and labels. Former UI controls (right click context menu, file menu) have been ported to the subproject jchart2d-uimenu (https://sourceforge.net/projects/jchart2d-uimenu.jchart2d.p/) for the benefit of having no dependencies to 3rd party libraries.
