i made sink. it's a simple little tool that continuously syncs folders between 2 devices. no cloud, no email, flash drives, no bs. it just uses your local wifi. run it on your machines, tell them to trust each other, and you're set. and if you manage to edit the same file at once, it handles the conflict and saves both copies. for anyone who just wants to get files from point a to b without the headache. hope it makes your life a bit less annoying. github: https://github.com/sirbread/sink binary:…

Hi HN, Today we’re launching PowerSync, a Postgres<>SQLite bi-directional sync engine that enables an offline-first app architecture. It currently supports Flutter, React Native and web (JavaScript) using Wasm SQLite in the browser, with more client SDKs on the way. Conrad and I (Ralf) have been working on our sync engine since 2009, originally as part of a full-stack app platform. That version of the system is still used in production worldwide and we’ve learnt a lot from its use cases and scaling. About a year ago we started on spinning off PowerSync as a standalone product that is…

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…

Hello HN. I worked on this small project recently called dsync. I have a few directories where I keep adding stuff and I need to sync them to an external drive from time to time. In the spirit of "write your own tools", I wrote my own. The tool itself is really simple. It tries to sync source directories or files to a destination directory based on size and modification time, basically copying the source files if they don't match. dsync can use multiple threads (specified via an option). It uses a bounded multi-producer multi-consumer queue (C implementation of Dmitry Vyukov's bounded MPMC…
