In plain words

btdu is a disk usage profiler designed specifically for btrfs filesystems. It samples disk usage patterns to help users understand how storage space is being consumed on their systems.

  diskard – A fast TUI disk usage analyzer with trash functionalityMar 2026 · github.com · ▲6

  This is an ncdu clone written in Rust that I figured others might find useful! The main things that differentiate it from ncdu are: - It's very fast. In my benchmarks it's often twice as fast. - It allows you to send files to trash rather than permanently delete. Please try it out and lmk if I can improve on anything!

  Dut – a fast Linux disk usage calculator2024 · codeberg.org · ▲396

  "dut" is a disk usage calculator that I wrote a couple months ago in C. It is multi-threaded, making it one of the fastest such programs. It beats normal "du" in all cases, and beats all other similar programs when Linux's caches are warm (so, not on the first run). I wrote "dut" as a challenge to beat similar programs that I used a lot, namely pdu[1] and dust[2]. "dut" displays a tree of the biggest things under your current directory, and it also shows the size of hard-links under each directory as well. The hard-link tallying was inspired by ncdu[3], but I don't like how unintuitive the…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
