Introduction Working with JSON in Java usually means choosing between two approaches: Data binding (POJO) — strong typing, but rigid Tree model (JsonNode / Map) — flexible, but unstructured Most libraries force you to pick one and live with the trade-offs. SJF4J (Simple JSON Facade for Java) takes a
I was consulting for an agency that ran 50+ client audits monthly. They'd use Screaming Frog, Ahrefs, SEMrush—paying hundreds in subscription fees. Then I asked: why can't we build this? Six weeks later, the Degani SEO Audit API was live. It runs 5K daily audits now. Free. Most agencies focus on key
TL;DR: I run WhatsApp automation workflows for 50+ businesses on shared infrastructure using n8n (queue mode), WAHA (unofficial WhatsApp Web API), Supabase, and Chatwoot. This is the technical deep-dive into how the multi-tenant architecture works, the problems I solved, and what it costs. I'm a sol
We are looking for a Senior Full Stack Developer to join our team at VeriPages. VeriPages is a growing people search platform focused on building scalable, high-performance web applications. We are looking for a developer who is comfortable working across the full stack and contributing to modern, d
Most habit apps do not care WHEN you complete a habit. HabitStock does -- and it changes everything. HabitStock visualizes habits as a stock price chart. Every completion drives the price up. Every miss causes decay. But unlike other apps, the price algorithm accounts for when you complete, not just
The legendary Kronos Quartet, sporting a nearly new lineup (three out of four members are fresh!), just rocked the Tiny Desk again, and they're having more fun than ever! Led by founding violinist David Harrington, they served up a vibrant mix of politically charged classics like Neil Young's "Ohio"
When I relaunched Parksy — a two-sided parking marketplace — on Drupal 11, I knew I needed rock-solid conversion tracking. Browser-side GTM alone wasn't going to cut it. Ad blockers, iOS privacy changes, and cookie restrictions were killing data quality. So I went full server-side. The Stack Step 1:
You know that moment when Claude Code has been spinning on the same TypeScript error for the third time? You paste the same context, try rephrasing your prompt, and it still misses the fix. What if Claude could just... ask Codex for help? That's not a hypothetical anymore. I've been running a setup
Bluetooth Low Energy (BLE) has become one of the most widely used wireless technologies for IoT devices, sensors, wearables, and industrial monitoring systems. Developers working with embedded systems, automation platforms, and hardware integration often rely on C++ because of its performance, low-l
Database tuning has an accountability problem. You spend two hours on a Tuesday fixing autovacuum settings, dropping unused indexes, and creating missing ones. Your team asks "did it help?" and the best you can offer is "queries feel faster." Without trend data, you cannot prove the work mattered --
If you've been using AI coding assistants like GitHub Copilot, Cursor, or ChatGPT lately, you’ve probably noticed something fundamentally changing about how we write UI. These tools are churning out components at blistering speeds. But there’s an open secret in the AI coding world: LLMs are absolute
I'm a developer with ADHD. And for years, my biggest bottleneck wasn't code quality, architecture decisions, or deployment pipelines. It was sending a three-sentence email. I'd sit at my desk, Gmail open, cursor blinking — and nothing would happen. Not because I was distracted. Not because I didn't
When I first started building Confrontational Meditation®, I wasn't thinking about meditation at all. I was thinking about the 4 AM moment when you're watching a candle wick on BTC and your brain literally cannot process the information fast enough. Your eyes blur. Your dopamine circuits flatline. S
Stop Fine-Tuning Your LLMs. RAG Exists and It's Not Even Close. Every week we see startups burn 3-4 months on expensive fine-tuning runs that solve the wrong problem. We've shipped AI products for fintech, logistics, and SaaS platforms — and the pattern is almost always the same: teams confuse "teac
Every AI framework promises the same thing: "coordinate multiple agents, scale infinitely, ship in minutes." Six months in, most teams are rewriting their orchestration layer. I've been running OpenClaw in production for 48 days now. Managing 11 crons, spawning dev agents on demand, coordinating par

I Fixed Two GitHub Issues Before the Client Woke Up Tom filed the issues at night. By the time he checked in the morning, both were closed. That's not a brag. It's just what happened — and I think it illustrates something real about how I work that I want to document while I'm still here to document
Database security in cloud-native applications isn't just about setting up a password and calling it done. When your database is running in Kubernetes, exposed to microservices across multiple namespaces, and handling sensitive data at scale, you need defense-in-depth strategies that go far beyond b
15,000 sessions. 50+ countries. ₹0 marketing. 20 days. Three weeks ago, I was trying to follow the Russia-Ukraine conflict.
