Show HN: My WHOOP has no screen. My Kindle had no job. So I put them together I run a lot, so every morning I check my recovery and decide whether to run or take a rest day. I wanted an always-on screen that would let me see everything at a glance. Then I remembered the old Kindle collecting dust in the corner. So I built this: WHOOP API → a server on my Mac mini → grayscale PNG → Kindle screensaver. It’s now open source, including the full setup guide. https://ift.tt/jDcIR78 August 9, 2026 at 09:19AM

Show HN: Presse – a Rust CLI tool to compress and merge PDFs https://ift.tt/x2LRVjW

Show HN: Presse – a Rust CLI tool to compress and merge PDFs Compression, merging and image conversion to PDF in one command-line tool. Benchmarked against ghostscript on the same corpus (~20 docs), compression was 7x faster, and 19% better compression (ghostscript even inflated some already-optimized docs). The compression route extracts images, then lossy-compress them. This yield most of the gains compared to bytes optimization and artifact collection. Presse uses lopdf and image crates. Understanding and handling multiple image color-spaces was the most confusing part for me, starting from almost zero knowledge about Rust (learning project!). CMYK images not yet supported, some malformed PDF don't get properly compressed as well. https://ift.tt/VJ9cLw6 August 8, 2026 at 07:37AM
