Show HN: A Gauss-Seidel solver visualization in a single HTML file Recently I was reading about fluid simulation and stumbled upon the Gauss Seidel method. I got interested in how it works and made a program that visualizes the method in action. I had the idea of making an interactive book-like thing for a while, so took this as a chance to do just that. Note that touch input doesn't work and the layout is targeted towards bigger screens, so it doesn't function properly on mobile. It was fun to make and I wanted to share it. Maybe someone will find it useful. Corrections and feedback are welcome. Technical Stuff - A single 1.7MB HTML file with embedded JavaScript and WebAssembly. You can save this single file and double click it to run. - A math typesetter from scratch in C that compiles/renders the equations in real-time (uses KaTex fonts and STB true type to rasterize the fonts). - Platform code is done using Sokol (tested on windows and web). - The UI is done using Dear ImGui (Most of the code is done in C++ to use ImGui without a wrapper except for the equations compiler). https://ift.tt/KCG58ls August 7, 2022 at 02:21AM
Women Pioneers at Muni: Adeline Svendsen and Muni’s First Newsletter By Jeremy Menzies To close out Women’s History Month, here’s a look back at one woman whose work to bring Muni staff together in the late 1940s created a legacy that lives on to this day. Adeline “Addy” Svendsen was founding editor of Muni’s first internal newsletter, “ Trolley Topics .” Adeline Svendsen sits at her desk in the Geneva Carhouse office building in this 1949 shot. Trolley Topics was a new venture when it started in February 1946. As Svendsen wrote in the first issue it was created, “to bring a little fun, a little news, and a lot of good will to all our fellow employees in the Railway.” Just two years prior in 1944, Muni merged with the Market Street Railway Company, expanding the small municipal operation into the largest transit provider in the city with hundreds of employees, vehicles of every shape and size, and dozens of facilities scattered across town. The newsletter was meant to help unite ...
