How I Built a Trading Value Tool for a Game With Constantly Changing Data

Game websites look simple from the outside. A player searches for an item, finds its value, and moves on. But once you are responsible for maintaining that information, you quickly realize that the difficult part isn't displaying the number. The difficult part is keeping the number useful. I ran i...

WordPress or Custom Development? The Decision Framework I Use With Clients

A client asks for a website. One agency recommends WordPress for $4,000. Another developer proposes a custom application for $15,000. Someone else says they can build it with Wix in a weekend. Technically, all three are offering a "website." But they are not offering the same thing. I work mai...

Oh-My-Pi's Hash-Anchored Edits: How a Terminal Agent Avoids the \\\\\\\"Replace Entire File\\\\\\\" Trap

Most coding agents fail at scale because they replace entire files when making small edits. One misaligned line number or stale context window and the agent clobbers unrelated code. Oh-My-Pi solves this with hash-anchored edits: the agent specifies a hash of the exact lines it wants to replace, and...

Unleashing WebGPU: Why Your Browser is About to Become a Massive Parallel Computing Beast

For decades, web developers have lived under a strict tyranny: the supremacy of the CPU. We’ve built magnificent architectures, optimized complex single-threaded event loops, and wrangled asynchronous JavaScript promises to deliver rich, interactive web applications. But when it came to heavy genera...

Coding Is Getting Easier. But System Design Still Matters.

Writing code is becoming easier. With AI tools, you can generate APIs, database queries, UI components and even complete features much faster than before. But building software isn't only about writing code. The bigger challenge is often how the entire system should work. Coding a Feature vs Des...

Node.js Healthtech Text Summarization SaaS — 4 Chat Completions API Trade-offs

Short answer: start a Node.js ticket-summarization SaaS with chat completions, put the provider behind one tiny adapter, and choose the vendor only after checking model availability, context limits, US/EU requirements, and batch support. Embeddings don't improve the first version of this job. They...

May the Source Be With You: Why Your AI Agent Is Only as Good as Its Knowledge

Everyone seems to be building AI agents. Give a model some instructions, connect a few tools, add a system prompt, and suddenly we have an "agent." Except there's a problem. A lot of them aren't particularly useful. When an agent produces a poor answer, the immediate assumption is often that the...

Your AI Agent Doesn't Need a Bigger Context Window. It Needs an Eviction Policy.

Every few weeks another framework ships a bigger context window and someone declares agent memory solved. It isn't. I've watched three separate production agents degrade in the exact same way — not because they forgot something important, but because they remembered too much and couldn't tell what m...

I analysed the 162 most popular Dart packages. 59% of what a scanner would flag never runs in your app.

I maintain capdrift, a tool that reads a Dart package and reports what it is able to do. I ran it across the 162 most-downloaded packages on pub.dev and kept the raw output. Here is what is actually in there. Method: capdrift inspect <pkg> --format json against each package's latest version,...

Sprix SAGE makes agent routing a stateful scheduling problem

Sprix AI has released SAGE Router, a public research prototype that chooses whether an agent should keep working, recruit collaborators, or hand a task to another agent. The consequence is less glamorous but more useful than another agent-discovery layer: it treats multi-agent routing as a decision...

9 RAG Techniques That Actually Improve Retrieval Quality

Retrieval-Augmented Generation (RAG) is often described as a simple pipeline: Query → Retrieve documents → Send context to an LLM → Generate answer In production, however, retrieval is rarely that simple. The retriever can return irrelevant documents. Important information may be buried in the...

Training vs. RAG: What's Actually Different (and Why AI Keeps Telling You to Use RAG)

"Can we just train the model on this data together?" is one of the most common things people ask an AI assistant. And almost every time, the answer comes back: "Let's use RAG instead." That answer sounds like a dodge if you don't know what's actually happening underneath it. It isn't. Training and R...

Stop chasing fads. Operate Claude like a startup founder.

I am running an AI-native startup. Early on though, I would spend so much time staying ahead of every new AI hot take that I lost focus on what I needed to do to move the company forward.

How I turned Linear into a customer-facing roadmap without adding client seats

Giving every customer a Linear seat was the wrong boundary. It exposed an internal workspace, added ac...

.NET 10 JSON Console Logging: Stop Parsing State.Message
