"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…

FreeUpMyMac▲110Hey HN Ex YC/Google engineer turned indie maker here - excited to share something I just shipped. The System Data in my Mac was taking up 300GB and it took me months to figure out how to clear the old cache, logs, junk and more. And CleanMyMac is a subscription - I refuse to pay subscription fees for Mac apps that run locally. So I built FreeUpMyMac an offline, lifetime Mac cleaner that clear junk with 1 click. And helps you visualize your storage with TreeMap/Sunburst. Hope it’s helpful to you as it is for me. Would love your feedback Tunde

GUI disk analyzers are great for figuring out what's filling up your laptop/desktop drive. On containers or remote servers, the options are limited to purely text based utilities (e.g. du) or list-centric TUIs (e.g. ncdu) which are usually limited to viewing one directory at a time. I created leaves to fill that gap. Inspired by classic utilities like WinDirStat and KDirStat, it uses a 2-dimensional treemap^1 visualization to show the entire directory hierarchy with proportionally sized rectangles. It's performant enough to handle millions of files, thanks to Rust and multi-threading.…

Hey HN! I’m the developer of Klarity Disk, a macOS disk space analyzer. I built this as an alternative to DaisyDisk ($9.99) because I wanted a modern disk analyzer without the premium price tag. Klarity Disk is $6.99 one-time on the Mac App Store. Some technical details: • Built natively for macOS • Efficient file system traversal for fast scanning • Visual representation of disk usage • Smart detection of reclaimable space Would love feedback from the HN community, especially on features you’d want in a disk analyzer. App Store:…
