Agent Memory with LangChain4j and Oracle AI Database

One of the quickest ways to make an impressive agent demo is to prepare a clever prompt. One of the quickest ways to make that same agent fall apart in production is to give it no durable memory. In this article, we'll build a small, memory-backed assistant with LangChain4j and Oracle AI Database. The assistant can search prior incidents, runbooks, decisions, and shift handoffs to answer question...

Claude Code Was Getting Dumber. Semantic Memory Fixed It.

I use Claude Code as my primary development tool. It manages a home automation stack spread across five machines — camera monitors, WhatsApp agents, LLM inference pipelines, job scrapers, diet trackers. Over two months, the codebase grew to 30+ services with their own ports, configs, credentials, and war stories. To keep Claude informed, I maintained documentation in .md files. camera_monitor.md....

Agentic Smells: From Qualitative to Quantitative

Introduction Every developer has had the same experience at least once. You pull down code someone else wrote and something is off. The tests pass, the function returns the right type, and the PR description is coherent. Yet, the code is shaped in a way no experienced developer would have shaped it, and still, you cannot quite say exactly what is wrong. Code Smells That...

My Security Cameras Were Dead for 3 Days. Now They Fix Themselves.

I run three AI-powered security cameras at home. RTSP streams feed into a Python daemon that runs OpenCV contour detection, sends cropped regions to a vision LLM on an NVIDIA DGX Spark, and fires WhatsApp alerts when it spots something. It works great — until it doesn't. On April 13th, the cameras silently died. No alerts. No crash. No logs. The process was "running." launchctl showed a healthy ...

I Built a Personal AI Engineer Using OpenClaw That Actually Helps Me Ship Faster

This is a submission for the OpenClaw Writing Challenge Stuck in My Own Code I remember staring at my screen for hours, rewriting the same function for the third time. I knew how to code, but every decision felt heavy. Should I use this framework or that one? What if this approach fails? The fear of failure kept me paralyzed, turning simple projects into endless loops of overthinking...

What AI Is Actually Doing to Your Critical Thinking

What AI Is Actually Doing to Your Critical Thinking

Here's a feeling that's probably familiar. You drop some documents into an AI tool, get a draft back, and then spend twenty minutes reading it to figure out if you agree with what you just "wrote." No critical thinking required. Just vibes and approval. Advait Sarkar calls this being "a professional validator of a robot's opinions." He's a researcher at Microsoft Research Cambridge, and I think i...

Stanford's 2026 AI Index just dropped. Junior developer employment is down 20%. Here's what the data actually says.

The Stanford Institute for Human-Centered AI released its 2026 AI Index today. It is the most comprehensive annual measurement of where AI actually stands — not where the press releases say it stands. One number is going to dominate headlines for the next week. Employment among software developers aged 22 to 25 has fallen nearly 20% since 2024, even as their older colleagues' headcount continues...

Twitter vs X: One Built Culture, the Other Wants to Build a System

Maybe the next dominant internet companies will not be pure social platforms. Maybe they will combine messaging, payments, creators, AI, subscriptions, verification, and commerce into one ecosystem. Maybe the old version of social media really is too narrow for the next phase of the internet.

Python Developer AI Toolkit, Part 2: Five CLI scripts that automate the prompts

Part 1 of this series covered the prompt library — 272 prompts for Python and backend development organized by task type. This is Part 2: the five CLI scripts that turn those prompts into automation tools you can run from the command line or wire into your development workflow. The goal isn't to replace your IDE or your existing toolchain. It's to make AI-assisted code review, test generation, do...
