Open-source schema based Change-Data-Capture utility for Postgres
I am currently working on a Node.js utility for a schema-based approach on CDC for Postgres. It is a lightweight utility that you can plug on top of your existing WAL events service (eg. Debezium, WAL-listener...) and allows you to define schemas to listen to. Instead of listening to raw individual table-level events, you can aggregate those events into high-level schema events automatically. Conceptually, it is like having WAL events but on an SQL view, any modification to a table the view is based on would trigger a high-level event on the view itself. This has many real-world applications…

In the maker’s words, at launch
I am currently working on a Node.js utility for a schema-based approach on CDC for Postgres. It is a lightweight utility that you can plug on top of your existing WAL events service (eg.

Conceptually, it is like having WAL events but on an SQL view, any modification to a table the view is based on would trigger a high-level event on the view itself. This has many real-world applications including: - Syncing your single source of truth (Postrges) to another store (eg. Elastic / Algolia...) - Have a reliable event-driven architecture where you can change the underlying data model while keeping the contract identical I was highly inspired by pgsync but wanted to build a lightweight, generic version of the idea that is not tied to any specific tech outside of Postgres. I am looking for early feedback on the idea to understand the traction and the direction I should give the project.

I was at FB/Meta from late 2013 to early 2023, mostly working in the compiler/runtime spaces. I got hit in the spring 2023 layoff wave. I immediately started making games in my newfound free time (a lifelong interest, and I even worked in AA(A?) back ca. ~2000), and in October 2023 I stumbled upon the idea of a roguelike pachinko/plinko game inspired by Luck Be A Landlord. Things snowballed quickly, I started talking to publishers, then worked like crazy through all of 2024, almost the hardest I've ever worked in my career, and launched the game in December 2024. It's sold…

i wanted to change the habit of reaching for my phone in the morning and doomscrolling away an hour so i built an app to help me. now i have to literally touch grass before accessing my most distracting apps the app is built in swiftui, uses the screen time apis provided by apple and google vision to recognise grass or not i'd love to get your thoughts on the concept.
