What it does
Lightweight file synchronization tool that wraps up fast file comparison and transfer algorithms into a simple and clear interface that offers you visual comparison of files before synchronizing and backing them up and support for two way synchronization.
Free bidirectional File Synchronization and Back up.
WinDataReflector is a lightweight file synchronization and backup tool that wraps up fast file comparison and transfer algorithms into a simple and clear interface that offers you visual comparison of files and folders before synchronizing and backing them up and support for two way synchronization with fully customizable rules. WinDataReflector supports synchronizing files and data to Google Drive, DropBox, OneDrive, FTP and SFTP. It can sync files between a local folder or network share and a cloud folder or two cloud folders. Changes made to either left or right folder are mirrored to the other folder making them identical and you can also configure WinDataReflector to only propagate…from veridium.net

Leaves – A text-UI disk usage treemap visualizerJul 2026 · github.com · ▲93GUI 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.…

This is a long-running project that started as the proverbial need to scratch my own itch and then somehow evolved into a full-time job of the past 6 years. Link: https://bvckup2.com I thought I'd do a Show HN for two reasons. 1. I obviously want to show my baby to those who haven't seen it. Its primary purpose is to do very fast file replication. If you are familiar with "robocopy /mir" - same idea, but on steroids. Lots of them. It can be used for both mirroring and archiving backups, among other things. It is light, very small and it is really quite fast. Half of the…

Talanoa▲346Hi 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…

After years of solo development I'm presenting: Angeldust, an omni-compatible action RPG and building game! Website: http://angeldu.st My single server hosts 250+K active players in one giant, dynamic fantasy world. Angeldust's game server is pervasively multithreaded, implementing John Carmack's dream of processing an immutable world state each tick. Both world handling and network traffic routing uses any number of threads. For networking, a typical game session only uses ~3Kbps of bandwidth, enabling decent play even over 2G/EDGE networks. The client is programmed in C++…
