  Hey everyone, I’m Weike, one of the founders of Stride, a more modern technical documentation + calculation software for engineers and other calculation-driven professionals. I worked as a structural engineer before and have always found the tools to create calculations (Excel and Mathcad mainly) to be unintuitive, terrible at communicating the intent of the calcs, and hard to integrate with my other tools. Honestly lots of it was just doing stuff on Excel, then screenshottinng it, and then putting it in a PDF document. Years later, I worked as a software engineer and saw all the fantastic…

  I built a(nother) house optimized for LAN parties▲1,117
