School Yourself provides free interactive online math lessons and videos. Subjects include algebra, geometry, trigonometry, precalculus and calculus. The site states the lessons are free with unlimited access, and describes smart recommendations and personalized assessments.
MathNet is a free dataset and benchmark of 30,676 Olympiad-level math problems with solutions, spanning 47 countries, 17 languages and two decades of competitions. It supports problem solving, math-aware retrieval and retrieval-augmented problem solving.
CESDb is the Civil Engineering Software Database, a site founded by engineers that lists free, trial or shareware civil engineering software for engineers, researchers and academics. It is described as currently listing 596 programs under 12 categories, with descriptions, screenshots and manuals where available. Programs can be downloaded for PC, Mac, Linux and other operating systems, and software reviews are provided.
A site that serves the version 5 KiCad libraries, providing schematic symbol libraries, PCB footprint libraries and 3D model data. The archived libraries are described as old, out-of-date and no longer maintained, with newer versions available from the KiCad website and GitLab. Users can clone the libraries with Git or SVN to receive updates.
