PGSync simplifies your data pipeline by integrating Postgres/MySQL/MariaDB into Elasticsearch/OpenSearch.

As my cat woke me up way too early for a Saturday morning, I decided to put all this extra time (and my ChatGPT Pro subscription) into good use and generated a QR-code generator for PostgreSQL, written as a single pure SQL statement. No external libraries or Postgres extension installation needed! I did this purely for fun and learning, I don’t think this is going to be the best way for generating QR codes in production. - Linux, Oracle, SQL performance tuning and troubleshooting - consulting & training.

Since June 2023, I’ve been running a service written in Ruby (Sinatra) that provides several Bluesky custom feeds (initially built with a feed for the iOS/Mac developers community in mind, later expanded to many other feeds). If you don’t know much about Bluesky feeds, you make them by basically running a server which somehow collects and picks existing posts from Bluesky using some kind of algorithm (chronological or by popularity, based on keyword matching, personal likes, whatever you want), and then exposes a specific API endpoint. The Bluesky AppView (API server) then calls your service passing some request parameters, and your service responds with a list of URIs of posts (which the API server then turns into full post JSON and returns to the client app). This lets you share such feed with anyone on the platform, so they can add it to their app and use it like any built-in feed. (If you’re interested, check out my example feed service project.)

My previous article about timezones turned out to be useful for quite a few folks, which makes me happy. One candle lights another. Ben Sheldon asked about then actually doing something with those converted times. How do you actually send a newsletter every morning on every working day, regardless of what the user’s time zone is? There are a number of approaches to this - once you know the UTC time of the delivery. I will cover a few of them, including the one I prefer. Let’s wind the clocks!
