I reverse-engineered the source code (v2.1.88) and found some surprisin...

4 products, 1 broadcasting infrastructure, 3 weeks, 1 non-technical founder

This is not a flex post. This is what happens when you stop planning and start shipping. I run NeuralChain Hub, a small company out of Dubai. Between March 27 and April 17, 2026, we shipped 4 digital products and built a production-grade live broadcasting relay server. None of this was planned as a batch. Each one came from a real problem that needed solving right now, not next quarter. Here is ...

How to prevent re-processing when reading pending entries (ID 0) in Redis stream using XREADGROUP?

I am using Redis Streams with Consumer Groups. I have a consumer running a loop that fetches messages from the Pending Entries List (PEL) using ID 0 before it attempts to read new messages. However, if a message fails to process (or is slow), the XACK is never called. On the next iteration of the loop, XREADGROUP returns the same messages again, causing re-processing. // Minimal version of my loop...
