All of my findings are shared online to anyone on the globe who could benefit from them, or make their own units. I'm an engineering student at the University of York, originally from Israel, studying in England. I too often have been hearing about tragic cases involving civilians in war zones being chas…

Show HN: SimpleW – Lightweight C# Web Server with optional addons Hi HN, I’m the author of SimpleW, an MIT-licensed .NET web server for standalone or embedded applications. I shared it here last year ( https://ift.tt/PoqlCKV ). Since then, I’ve rewritten it from scratch, removing the NetCoreServer dependency.

Show HN: Interactive Tree of Life https://ift.tt/iXOtDa1
Show HN: Interactive Tree of Life Ptree consolidates of 11 taxonomic trees, both categorical like we used in school (plant, animalia) and phylogenetic (evolutionary descent), with instant crosswalk between them. Across those trees it overlays 41 visual properties (categorical and numerical) assembled from hundreds of biological traits and sources. Color the tree by habitat, nutrition, size, longevity, even see vertical range of birds and depth of fish visually. The backend is 800 GB of raw data distilled through a 9-step build process that rec…
