Show HN: Nova: Open-source solution for CAD file conflicts Hey HN,

A friend at a hardware startup mentioned how their engineering team struggles with CAD file conflicts as PDM solutions are not affordable. Multiple engineers opening the same SolidWorks part = corrupted files and lost work.

I was motivated and started building Nova. Nova is a open source file locking system, designed to support multiple CAD softwares with real time locking and live dashboard to keep design engineers in sync.

Nova is built with python and Next.js.

Get started with -

  git clone https://github.com/agg111/nova
  cd nova
  pip install -r requirements.txt
  nova start
  nova --help (for more commands)
Open http://localhost:3000 in browser

I am looking for early users to get some feedback and learn about more features or bottlenecks that mechanical design teams currently face.

Show HN: A terminal spreadsheet editor with Vim keybindings

Show HN: A terminal spreadsheet editor with Vim keybindings While speccing out this spreadsheet tool, I realized that I never had to think about the keybindings. It all just came naturally from Vim. Normal&#x2F;insert&#x2F;visual modes, hjkl navigation, dd&#x2F;yy&#x2F;p, :w, :q. The usual muscle memory works.<p>It supports CSV&#x2F;TSV import and export, and a native .cell format that preserves formulas. The formula engine handles SUM, AVERAGE, COUNT, MIN, MAX, and IF with range references.<p>The codebase is a Cargo workspace: a pure cell-sheet-core library (no TUI dependency) and a cell-sheet-tui crate on top of ratatui. Early days, but it&#x27;s usable.<p>To try it out: cargo install cell-sheet-tui<p>Feedback of any kind is greatly appreciated!
