Solon Cache: Three Annotations, One Interface, and a Tags Trick You'll Use Every Day

I've been writing Solon for a while now, and one thing that surprised me early on was how clean the caching layer is. Not because it does anything revolutionary — it doesn't — but because it stays out of your way while still handling the edge cases you actually hit in production. Let me walk through what I've learned. The Three Annotations Solon gives you exactly three annotations for...

How to Generate Short Videos from Claude.ai with a Seedance MCP Connector

Sometimes the fastest way to prototype a video idea is not to open a separate generation dashboard, but to let your assistant create and poll the task while you stay in the conversation. This guide shows how the Seedance MCP connector works inside Claude.ai, based on the Ace Data Cloud documentation. The workflow is practical: add one remote MCP URL, authorize with OAuth, ask Claude to list avail...

Your Agent's Deadline Is a Correctness Test, Not an SLO

Ask an engineer to list their agent's failure modes and you'll hear about hallucinations, wrong tool calls, and bad JSON. Ask about time and you get a shrug. Yet the single most common thing a production agent does when it goes wrong is not fail loudly — it just takes too long. It loops. It retries a flaky tool. It waits on a model call that never streams a first token. And your eval suite, which ...

Is anyone truly fulfilled by this career?

I go through days of feeling grateful for the career I have, feeling motivated and looking forward to the work, and then I go through long spells where I just can’t stand it and feel trapped. Days where I truly don’t give a shit about any of it and would have no problem rubber stamping PR’s and just “getting it done”. This isn’t about AI or anything (if anything AI has made it easier to just menta...

A league season is not a long tournament: four product bugs my test suite could never catch

I built a football prediction game for the 2026 World Cup. A month long, 104 matches, one winner at the end. It worked, people played, nothing caught fire. Then I pointed the same app at a domestic league: Ligue 1, 306 matches, 34 matchdays, nine months. Same data model, same scoring, same templates. Nothing crashed. Nothing threw. Every test stayed green. And almost every product decision insid...

Why I Validate Angular Compatibility Using the Published npm Package (Not the Source Code)

I just published a new article on a lesson I learned while maintaining my open-source Angular library. I used to validate compatibility against my workspace and dist/, but eventually realized that wasn't what developers actually install from npm. That led me to redesign the CI pipeline to validate the published package across multiple Angular versions instead. The article covers: Why testing ...

How I Automated Ubuntu Server Hardening with One Script

Securing and Automating a Cloud Server The first time I spun up a cloud server, I thought the hard part was over. It wasn't. The server was open to the world: root login enabled, port 22 broadcasting itself to every scanner on the internet, no firewall, and no certificate. I checked /var/log/auth.log a few hours later and found hundreds of failed login attempts. That was the moment I u...

PIVOT Explained — From Paper to Working Code in 10 Minutes

You enabled sparse attention. Your model still chokes at 128K tokens. The indexer is why — and PIVOT fixes it without touching your weights. TL;DR Sparse attention's indexer scores all L tokens per query → still O(L²) PIVOT groups nearby queries (which select ~90% overlapping top-k tokens), runs one proxy scan per group → O(L²/g) Result: 4× indexer speedup, 1.6× end-to-end latency red...

The $26 Billion Leak: Why Frameworks Are Making Your Codebase Rot (and How Hexagonal Isolation Fixes It)

According to a 2024 vFunction survey, over 50% of companies watch more than a quarter of their entire IT budget vanish into technical debt. This isn't happening because developers are bad at writing code. It's happening because our architectural boundaries are eroding. We're letting business rules bleed into database models, and HTTP controllers bleed into core logic. The primary culprit? Modern...

When a Successful Payment Still Couldn't Schedule a Zoom Meeting

This is a submission for DEV's Summer Bug Smash: Smash Stories powered by Sentry. A payment webhook sounds simple until a successful payment doesn't actually result in the service the customer paid for. That was one of the more interesting bugs I encountered while building The Listening Ear, an appointment and online consultation platform. The requirement was straightforward: A customer pays ...

Restaurant Health Inspection Data by City: APIs and Traps

Most large US cities publish restaurant inspections through the same Socrata Open Data API. That uniformity is a trap. The transport is identical; the column names, the score polarity, the row granularity, and the update cadence are not. This guide lists seven municipal datasets and the specific failure modes I hit while querying every one of them live on 2026-07-20. Every number, column name, an...

Reviving the Tessel 2 - The Boards in the Drawer

When I first joined Microsoft, I was doing a lot with JavaScript and hacking around a bit with IoT. Because of this, one of my colleagues sent me a box of Tessel 2 boards and sensors they had lying around. I had never heard of Tessel before, but I was intrigued by the idea of a microcontroller that could be programmed in JavaScript (I’d dabbled a bit with that using NodeMCU in the past). I d...

Image verification, one layer below admission

Every admission webhook you rely on has an escape hatch. Nothing scandalous about that, it is just how Kubernetes wires them up. A CNCF post on July 30 pitches a way out: move signature and attestation checking out of the API server and into the container runtime itself, via a Node Resource Interface plugin. The pitch, in one paragraph. The Supply Chain NRI Plugin hooks CreateContainer events on ...

CISA KEV catalog: a working sysadmin's guide to actually using it

Most enterprise teams know the CISA Known Exploited Vulnerabilities catalog the same way they know the weather: a headline scrolls past ("CISA adds three vulnerabilities to KEV catalog"), someone forwards it, and everyone nods. That is a waste of the single most operationally useful list in vulnerability management. The KEV is small, machine-readable, updated near-daily, and every entry on it has ...

Stopping Runaway AI Loops: Implementing Enterprise FinOps and Observability with PolicyAware

Autonomous agents don't just fail loudly—they fail expensively. A single misconfigured retry loop between an agent and an LLM can generate thousands of redundant tool calls and API requests before anyone notices, turning a minor logic bug into a five-figure cloud bill. PolicyAware is built to be the operational safety net that catches this class of failure before it reaches your finance team's das...
