Postgres pipelines from the JVM with Bpdbi

Every time your JVM app talks to Postgres, something wasteful happens. Your code sends a query, waits for the response, sends the next query, waits again. Each wait is a full network round-trip with a typical latency of 0.5-2ms in a cloud environment. For a simple transaction with a few queries, that's 8-10ms of just... waiting. This problem is exacerbated by the additional queries that are commo...

Deploying AG-UI Agents to Production with Amazon Bedrock AgentCore

The Agent-User Interaction Protocol (AG-UI) standardizes how AI agents communicate with user applications. But deploying those agents means the same manual work: configuring SSE endpoints, writing auth middleware, managing session isolation, and setting up auto-scaling. None of that is your agent logic. All of it had to be built before you could ship. Amazon recently announced native AG-UI suppo...

Show HN: Gridland: make terminal apps that also run in the browser

Hi everyone,Gridland is a runtime + ShadCN UI registry that makes it possible to build terminal apps that run in the browser as well as the native terminal. This is useful for demoing TUIs so that users know what they're getting before they are invested enough to install them. And, tbh, it's also just super fun!Gridland is the successor to Ink Web (ink-web.dev) which is the same concept, but using...

10 Years of Event Sourcing: Architecture, Ecosystem, and Lessons Learned

I’ve been working on an event-sourced, message-driven architecture over the past decade—used in production systems (including legal and financial systems)—that gradually evolved into an open-source ecosystem. This write-up looks at: - How the architecture developed over time - How the implementation evolved (including a PostgreSQL-based event store) - How the work has been distributed across contr...

Stop Guessing Why Your App is Slow: A Pragmatic Guide to Big O Notation

Let’s be real for a second. When we start coding, our main goal is just making things work. If the feature ships and the bugs are squashed, we’re happy. But then, your user base grows, your database swells, and suddenly that simple array iteration is freezing the browser. This is where Big O Notation comes in. Forget the heavy academic math for a minute. Big O is simply a way to talk about how...

# Finding First and Last Occurrence in a Sorted Array (Java)

When working with sorted arrays, one common problem is to find the first and last occurrence of a given element. This becomes especially interesting when the array contains duplicate values. In this blog, we’ll walk through an efficient approach using Binary Search and implement it in Java. 🚀 Problem Statement Given a sorted array arr[] (possibly with duplicates) and a number x, fi...

How to Run NemoClaw with a Local LLM & Connect to Telegram (Without Losing Your Mind)

I just spent a full day wrestling with NemoClaw so you don’t have to. NemoClaw is an incredible agentic framework, but because it is still in beta, it has its fair share of quirks, undocumented networking hurdles, and strict kernel-level sandboxing that will block your local connections by default. My goal was to run a fully private, locally hosted AI agent using a local LLM that I could text ...

I'm Building: AgentGuard360: Free Open Source AI Agent Security Python App

I've been posting on Reddit about an open source agent security tool I'm building called AgentGuard360, and I thought I'd share information about it here as well. What makes this app unique is its dual-mode architecture and privacy-first engineering. It features tooling that agents can use directly, and a beautiful text-based dashboard interface for human operators. It also has privacy-first se...

5 Interview Mistakes That Cost Me Offers at FAANG Companies

Over the past three years, I've interviewed at Google (twice), Meta, Amazon, Apple, and Netflix. I got rejected by four of them before finally landing an offer. That's a lot of rejection emails. But it's also a lot of data. Every failure taught me something specific — not generic "practice more" advice, but concrete, tactical mistakes that I didn't even realize I was making until it was too late...

1. SELECT title, special_features FROM film WHERE special_features IS NULL; This question is asking us to find movies where no special feature is given at all. So instead of checking for empty text, we use IS NULL because NULL means “no value stored”. 2. SELECT title, rental_duration FROM film WHERE rental_duration > 7; Here we only want movies whose rental duration is greater than 7 days. S...

A Tiny CLI for Inspecting and Freeing Busy Ports

Busy ports are one of those tiny problems that interrupt real work far more often than they should. You start a dev server, a local database, a preview app, or a test runner, and something fails because a port is already in use. Then the usual dance begins: check what is using the port figure out whether it is safe to stop kill the process retry your actual work That friction is exactly why I...
