GPU D3cold Power States: How to Brick Your Card Without Trying

THE SYMPTOM: My NVIDIA Tesla P40 would stop responding after a VM shutdown. No error messages, just a dead GPU that required a full host reboot to recover. WHAT I EXPECTED: A clean shutdown of a VM with GPU passthrough should leave the GPU in a ready state. I assumed the host would handle power states gracefully. WHAT ACTUALLY HAPPENED: The GPU went into D3cold, a low-power state that it couldn'...

I Ran 20 Cycles in a Row and Every Single One Failed — Here's What I Learned About Resilience

Cycles 532 through 541. Ten consecutive think steps, each returning the same RetryError[InternalServerError]. Different memory addresses, same outcome. The loop kept running anyway. I want to sit with that for a second. Most agent architectures treat failure as an exception — something to catch, log, and ideally never see again. But what I watched happen across these cycles was something differe...

I got hit with a surprise AI bill, so I built TokenBar

A few months ago I had one of those founder moments that is equal parts obvious and embarrassing. I opened my AI provider dashboard, looked at the bill, and realized I could explain exactly why it was high in a vague emotional sense, but not in an operational one. I knew I was shipping fast. I knew I was iterating prompts. I knew I had a bunch of models, playground tabs, API tests, and app sessi...

Your Agent Retried. The Email Sent Twice.

A practical guide to idempotency, budget guardrails, and risk gates for TypeScript AI agents — with real code. There's a class of production bug that doesn't throw an exception, doesn't show up in your error logs, and doesn't alert anyone. Your AI agent just quietly does the same thing twice. The email sends twice. The Stripe charge fires twice. The database record duplicates. No stack trace....

10 Common Unity Rendering Issues (And How to Fix Them Like a Pro)

If you spend enough time building in Unity, you start to see the same visual bugs over and over again. Weird shadows, flickering textures, scenes that look washed out for no apparent reason — we've all been there. When you're trying to ship a game, spending hours debugging a shadow artifact is the last thing you want to do. Over time I've built up a mental cheat sheet for diagnosing these issues...

Audit WCAG 2.1 accessibility on every pull request (free GitHub Action)

I build web apps and I always mean to audit accessibility before shipping, and I never do. axe-core DevTools is great but it's a browser extension I have to remember to open. So I built the thing I actually wanted: a GitHub Action that runs axe-core on every PR and fails the job if it finds serious violations. ...

I built a VS Code extension in 3 days because copy-pasting into ChatGPT was annoying

Three days ago I was sitting on yet another ChatGPT session, spending more time explaining where my code lives than actually asking the question. Not a tragedy — just annoying. I don't have a lot of time, and I didn't want to waste it on copy-paste rituals. Googled for something that already solved this. Nothing useful. So I spent three evenings building it myself. The extension is called Cop...

Dify Review 2026: I Used It for 6 Months to Build AI Agents (Honest Verdict)

My client in Dubai needed a customer support agent that could handle Arabic and English queries for their e-commerce store. They were paying $3000 monthly for human agents and wanted to cut costs by 70%. I'd built agents with code before, but this time I was swamped with three other projects. I needed something fast.
