Why Your Bank's FD Rate Is Not the Best Rate Available Right Now

If your FDs are sitting in SBI, HDFC, or Kotak, you are almost certainly leaving 1-2% per year on the table. For a Rs. 10 lakh FD, that is Rs. 10,000-20,000 in foregone income annually. Over 3-5 years, compounded, the gap is significant. Here is why large banks pay less - and where you can safely earn more. Why Large Banks Pay Lower FD Rates Large PSU and private banks have massive, low-cost deposit bases. SBI has over 50 crore savings account holders who are happy earning 2.7-3% on their balances. This cheap deposit base means the bank does not need to compete aggressively on FD rates to fund its loans. ...

How to Build a Second Brain Without Buying 14 Different Apps

The productivity industry loves selling you the idea that the right app will change your life. If you just found the perfect note-taking system, the ideal task manager, the optimal calendar setup - then you would be productive. It is a trap. The engineers who are most productive have boring systems. Simple ones. Systems that would not make a good YouTube video because there is nothing impressive to show. What a Second Brain Actually Is The concept, popularized by Tiago Forte, is simple: your brain is for having ideas, not for storing them. An external system that captures, organizes, and surfaces information when you need it extends your cognitive capacity. ...

Why PostgreSQL Full-Text Search Is Good Enough for Most Apps

Every time someone adds search to their app, the default advice is “spin up Elasticsearch.” That advice is expensive, operationally heavy, and usually wrong. PostgreSQL has had solid full-text search since version 8. For 90% of apps, it is genuinely good enough. How PostgreSQL Full-Text Search Works Postgres converts your text into a tsvector - a sorted list of normalized lexemes (words stripped of suffixes). Queries use tsquery to match against those vectors. The core functions are to_tsvector and to_tsquery. ...

The Open Source AI Tools That Replaced Our $50K SaaS Stack

Eighteen months ago our AI tooling bill crossed $50,000 per year and kept growing. Commercial LLM APIs, a vector database with per-query pricing, an embedding service, an AI observability platform, and a prompt management tool. Each individually defensible. Together, unsustainable.

The GraphQL Mistakes That Tank Performance at Scale

GraphQL’s promise is efficient data fetching - clients request exactly what they need. The reality is that flexible queries create performance problems that REST APIs rarely encounter. These are the specific issues that appear when traffic scales, and the fixes that work. The N+1 Problem Is Worse in GraphQL In REST, a poor implementation causes N+1 queries. In GraphQL, N+1 is the default behavior without explicit mitigation. query { posts { # 1 query: SELECT * FROM posts LIMIT 20 title author { # 20 queries: SELECT * FROM users WHERE id = ? name } } } The resolver for author fires once per post. The schema makes this natural to write. The database sees 21 queries. ...
