  An HP 15C themed TUI RPN calculator2024 · github.com · ▲8

  Recently, I found a long desired framework that treats the terminal via a DOM/CSS approach named Textual [https://textual.textualize.io]. In order to explore this framework I started developing a terminal based TUI RPN (styled in the aesthetic of a classic HP 15C pocket) calculator. So far this TUI RPN calculator has classic HP styled buttons, LCD display and some of the basic math operations. This is very much a W.I.P. Any engagement welcome.

  Modeleon – Python DSL that compiles to live Excel formulasMay 2026 · github.com · ▲6

  Hi HN. Modeleon is an open-source Python DSL for financial models. You write models in Python with named variables and operator-overloaded arithmetic, and it compiles to a real .xlsx with live formulas — not values, but formulas like =B4*B5 that the CFO can audit in Excel. The architectural bet is "model is the source of truth, spreadsheet is one rendering." We have a Walker/Renderer split so the same model can target Excel today and other backends later. We've been building this for finance + Python developers (CFA candidates with Python skills, FP&A analysts who automate). It's…

  22 GB of Hacker News in SQLite▲730

  Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
