I saw a guide some time ago on the topic of building a spreadsheet software. It is not anonymously written, and it's not on spam platforms like medium or substack, it's hosted on its own (a personal blog? a dedicated site? a github page? I'm not sure).<p>The guide is in written form, very profound, and discusses entire process from ground up. The author tells about their own experience, explains about different trade-offs and edge-cases.<p>Would really appreciate, if someone shares the link with me.
<a href="https://av.tib.eu/media/20123" rel="nofollow">https://av.tib.eu/media/20123</a><p>This is a talk from EuroPython 2015 on how to build a spreadsheet in python.
