PostgreSQL Row-Level Security Saved My SaaS From Bugs I Didn't Know I Had

PostgreSQL Row-Level Security Saved My SaaS From Bugs I Didn't Know I Had I build Nokos, an AI note-taking app. Every user's memos, diaries, and coding sessions are stored in one PostgreSQL database. One authorization bug = one user sees another's private data. Most apps have one layer of defense: application-level auth checks. We have two. The second layer — PostgreSQL Row-Level Secur...

If this agent really learned from its own failures, “just add more context” is officially dead. We thought our agent was nondeterministic. It wasn’t. It was consistently wrong in ways we couldn’t see—until we added Hindsight. We built a tool-using agent and wired in Hindsight to record + replay every run.

AI-generated code is clean, well-structured, properly commented, and follows conventions. A function wr...

Choosing MongoDB Was The Biggest Mistake Of My College Life😥

It was the final year of my college, and I was left with 6 months to build my major project, which was a healthcare app {(Patients), (doctors), (appointments), (prescriptions)} All data were connected to each other in a hierarchical relation. I picked MongoDB because people around me were using it. Spent two months building on it, hit three problems I could not cleanly solve, and migrated to Pos...

Best Tools to Build MongoDB Aggregation Pipelines in 2026

Aggregation becomes difficult when you have to visualize the data as it changes in your mind. Visual aggregation builders address this issue. Instead of writing complex JSON queries, you can add one stage at a time, time, see the results, and observe how the data changes in real time. In this post, I will create a small pipeline from the payments collection and replicate it in five tools: ...

AI study companion

“Why did it explain that concept differently this time?” I checked the logs and realized our study companion had pulled my past confusion from Hindsight—and rewrote its explanation to avoid the exact mistake I struggled with earlier.
