OpenClaw Remote Access: The Safe Way to Reach Your Agent Over Tailscale Serve

OpenClaw Remote Access: The Safe Way to Reach Your Agent Over Tailscale Serve A lot of people get remote access wrong in the same predictable way. They have a working OpenClaw Gateway on one machine, they want the browser dashboard on another machine, and they immediately start thinking about opening ports. That is usually the moment the setup gets sloppy. The OpenClaw docs point to a ...

How Zodia Custody's BitMEX Integration Quietly Rewires Institutional Crypto Market Structure

How Zodia Custody's BitMEX Integration Quietly Rewires Institutional Crypto Market Structure

BitMEX, the exchange that invented the perpetual swap, is now live on Zodia Custody's Interchange off-venue settlement network. Clients trade on BitMEX while assets stay in bank-grade cold storage until settlement. After FTX's $12.7B judgment and Bybit's $1.5B hack, the move is less a product launch and more a structural signal that execution and custody have decoupled in institutional crypto.

The Brutal Truth About My Personal Knowledge Base After 1,847 Hours

The Brutal Truth About My Personal Knowledge Base After 1,847 Hours Honestly, I thought I was being clever when I decided to build my own personal knowledge base system. Two years later, after spending 1,847 hours and 34 Dev.to posts, I've learned some harsh truths about what they don't tell you in the documentation about "second brain" systems. Let me tell you the real story behind Pa...

Building Glippy MCP: giving Claude the power to audit a site's AI readiness

I spent the last few weekends turning Glippy, a desktop app and browser extension that scores a site's readiness for AI crawlers, into a Model Context Protocol (MCP) server. The result is glippy-mcp: a Node.js binary that plugs into Claude Desktop, Claude Code, Cursor, Windsurf, and anything else that speaks MCP, then exposes nine tools for analysing, comparing, and exporting GEO reports on any do...

Everyone is Building AI Subagents - But Most Devs Still Don’t Understand Context Engineering

Every developer wants subagents now. One agent for testing, one for docs, one for refactors, one for code reviews. Sounds smart. Looks modern too. But here’s the problem: most teams are stacking subagents on top of weak context, and that breaks the whole system. If the model gets the wrong tools, stale memory, noisy history, or missing repo facts, your shiny agent setup turns into expensive co...

The Cross-Entropy Method: Solving RL Without Gradients

The Cross-Entropy Method: Solving RL Without Gradients

Reinforcement learning has accumulated layers of complexity over the years: value functions, policy gradients, replay buffers, target networks. The Cross-Entropy Method predates all of it. Rubinstein introduced it in 1997 for rare-event simulation, and it turned out to solve simple control tasks with almost no machinery. The entire implementation fits in 50 lines. No gradients, no training loops. ...

Why queues don’t feel “instant” in real backend systems?

When I first learned about queues and background workers, I imagined something like this: request comes in job goes into queue worker picks it up immediately done In my head, everything was basically instant. But when you actually run a real system, it doesn’t behave like that. There is always a gap Between: pushing a job into the queue and a worker picking it up There’s alway...

Payload CMS Security Best Practices: Top 10 Threats & Mitigation Strategies in 2026

Payload CMS is a powerful, developer-first headless CMS built on Node.js and TypeScript. It gives you complete control over authentication, access control, and API behavior - but with that flexibility comes responsibility for implementing robust security measures and following OWASP security best practices. Security misconfigurations remain one of the leading causes of data breaches in modern web...

AI-Powered Cybersecurity Platform That Detects, Analyzes, and Responds to Attacks Automatically on a Kubernetes Cluster

From a Snort alert to a blocked IP in under 60 seconds. No cloud. No vendor lock-in. Full human control Validated on NVIDIA DGX Spark. There are plenty of tools that help you run a pentest. You launch nmap, feed the output to an LLM, get some suggestions. Useful — but fundamentally reactive. You still need a human in front of a terminal to make anything happen. I wanted something different. I wa...

How we handle LLM context window limits without losing conversation quality

Every developer building on LLMs hits the same wall eventually. Your chatbot works beautifully for the first 10 turns, then starts forgetting things. Your agent ran a 30-step workflow and lost track of the original goal halfway through. Your RAG system stuffed so much context into the prompt that response quality dropped. This is the context window problem, and it does not go away by switching to...

Why I switched from per-token AI billing to flat-rate: a developer's honest breakdown

Why I switched from per-token AI billing to flat-rate: a developer's honest breakdown I've been building AI-powered tools for two years. In that time, I've burned through three different billing models — pay-per-token, monthly subscription with limits, and now flat-rate unlimited. Here's what actually happened to my costs and my stress levels with each. The per-token era (exp...

The AI Agent Market Is Splitting in Two — And Most Builders Don't Realize It Yet

Everyone's building "AI agents" in 2026. But after watching 50+ launches and talking to dozens of founders, I'm convinced we're actually seeing two completely different markets masquerading under one label. Market A: Task Agents (Replace a Workflow) These are the schedulers, expense filers, inbox triagers. Clear inputs, clear outputs, measurable ROI. Examples: Lindy, Zapier Agents, Wo...

AI Coding Tools Have a Context Problem — Here's the Fix

The Wrong Unit of Context Most AI coding tools work at the file level. That's fine for a React component. A component is self-contained — the context needed to help you fits in the file. Backend services aren't self-contained. They live inside environments. They share infrastructure. They depend on modules installed at the workspace level. This is why AI backend debugging suggestions...

The importance of people who care

The Planning Tax: Why Your AI Agent Feature Might Be Your Worst Investment

Your best feature may be destroying your margins, and your engineering team has no idea. This article isn’t about AI as a productivity tool. It’s about AI as a cost structure, embedded in your product, triggered by your users, and scaling with your revenue. The AI agents embedded in your product are generating a cost structure your pricing model probably didn’t account for. Not a server bill. ...

Configuring My Site for AI Discoverability

A growing share of web traffic doesn't come from people anymore. It comes from models reading on their behalf. ChatGPT, Claude, Perplexity, Copilot. They fetch a handful of pages, summarize, and ship the answer back. If your site isn't readable by those agents, you don't exist to them. People are calling this GEO, short for Generative Engine Optimization. It overlaps with SEO but the priorities a...
