Why Math.random() Will Fail Your Next Security Audit

If you have ever written something like this in a production codebase: const secret = Math.random().toString(36).slice(2); You have shipped a credential that will fail a security audit. Not might fail. Will fail. Here is why that matters and what to do about it before your auditors find it first. With the renewed focus on Executive Order 14028 and software supply chain security, auditors are no ...

Announcing Fuik: a webhook engine for Rails

Webhooks are one of those super simple but really powerful tools that almost every developer has needed to use at least once. From Stripe, GitHub to Postmark. Setting up webhooks is not difficult, but there is quite a bit of boilerplate involved: payload storage, event routing and signature verification. Repetitive. Tedious. Boring. Oh, and did I mention debugging? Meet Fuik : a Rails engine that...

What if you could reverse a template engine?

I've been building software for over 20 years across banking, healthcare, financial SaaS, and media. At Stuff, one of New Zealand's largest news platforms, I worked on systems that consumed and produced structured content at scale. In banking and healthcare, I dealt with legacy systems that predate REST APIs entirely: fixed-format financial reports, statement exports, internal tools that print str...

How we built multi-region uptime consensus on the BEAM — zero external dependencies

Originally published at uptrack.app/blog/multi-region-consensus The 3am problem UptimeRobot checks your site from one location. A CDN edge goes down in Frankfurt. Your server in Virginia is fine. Your users in Tokyo see no issues. But the single check from Frankfurt fails, and your phone buzzes at 3am. This is the false alert problem. Single-region monitoring can't distinguish between...

Launch HN: Twill.ai (YC S25) – Delegate to cloud agents, get back PRs

Hey HN, we're Willy and Dan, co-founders of Twill.ai (https://twill.ai/). Twill runs coding CLIs like Claude Code and Codex in isolated cloud sandboxes. You hand it work through Slack, GitHub, Linear, our web app or CLI, and it comes back with a PR, a review, a diagnosis, or a follow-up question. It loops you in when it needs your input, so you stay in control.Demo: https://www.youtube.com/watch?v...

Deepfakes Surged 2,137%. Courts Rewrote the Rules. Investigators Didn't.

The reality of synthetic identity fraud in 2025 For developers building in the computer vision (CV) and biometrics space, the signal-to-noise ratio just hit a catastrophic tipping point. We are no longer in the era of "detecting" fakes; we are in an era where the assumption of digital authenticity has become a technical liability. When deepfake fraud surges by 2,137% in a three-year window, the...

Why Do Local AI Agents Forget You?

Every local AI agent I built before this one had the same problem: restart the session, and it had no idea who I was. The fix wasn't a better model; it was treating memory as structured persistent data outside the context window, using memory, storage, and LLMs, all running locally. This post walks through exactly how I wired the full stack together, including the two silent gotchas that will quie...

Delivery Slowdown in AI-Generated Codebases — Why Every Sprint Takes Longer Than the Last

Delivery Slowdown in AI-Generated Codebases — Why Every Sprint Takes Longer Than the Last

"Six months ago, we shipped features in two days. Now a single change takes two weeks." If you've built an application with AI tools — Cursor, Lovable, Bolt.new, Replit, v0 — and you're past the first few months of development, there's a good chance your delivery speed has declined. Not gradually. Sharply. This is not a team problem. It's a structural one. The Mechanism: Verification D...

Hotwire vs Next.js in 2026: Is Server-Centric HTML the End of SPA Bloat? [Compared]

The median mobile webpage ships over 460 KB of JavaScript, according to the HTTP Archive's Web Almanac. That was 2022. It's gotten worse. Meanwhile, David Heinemeier Hansson, Creator of Ruby on Rails and CTO at 37signals, has been waging a very public war against SPA-by-default architecture, championing Hotwire as the antidote. Bold claim. But when you actually compare Hotwire vs Next.js on real m...

The Standup Chaos Simulator

This is a submission for the DEV April Fools Challenge What I Built Most of us have sat in standups that somehow consumed time, generated stress, and produced zero meaningful decisions. So I decided to make a useless app to remember these moments in all their chaos and glory. Behold Standup Chaos Simulator, a web app that generates chaotic developer standups in a chat UI.

How I Deployed a Static Website with Azure DevOps, Terraform, Ansible, and Nginx

There is something about pushing code and watching a website update itself on a live server that never gets old. No manual uploads. No FTP. No SSH copying. Just a commit, and the pipeline takes care of everything else. This is Project 2 in my Azure DevOps series. In this one, I deployed a static finance website to an Ubuntu VM running Nginx, fully automated with a CI/CD pipeline that triggers on ...

From Futures to Runtimes: How Async Rust Actually Works

From Futures to Runtimes: How Async Rust Actually Works

Introduction to Asynchronous Programming In synchronous programming, tasks execute linearly one after another on a single thread. fn synchronous() { println!("1st"); println!("2nd"); println!("3rd"); } For many situations this works great, but if a single task in the chain is slow the entire program halts as we wait for it to finish. This is called "blocking" the thr...

AI Agent Monitoring: How to Observe Autonomous AI Agents in Production

AI agent monitoring — also called LLM observability — is the practice of collecting, analysing, and acting on telemetry data generated by LLM calls and the autonomous agents built on top of them. Think of it as traditional APM, but purpose-built for AI workloads. A modern AI agent is not a static API call. It's a dynamic, multi-step reasoning system that may: Plan and decompose subtasks autonom...

How to Extract PDF Coordinates for Signature Placement in C# (Without Uploading Your Files)

If you've ever tried to programmatically place a signature box on a PDF using iText7, you know the pain: you need exact llx, lly, urx, ury coordinates — and getting them right is a tedious, trial-and-error nightmare. You either hardcode guesses, write throwaway debug code, or upload your document to some random online tool (and hope it's not storing your sensitive contracts). There's a better wa...

The Monster and the Machine: Why My Best Code Only Happens Between 2 and 5 AM

The house doesn’t make noise at that hour. Not silence exactly. More like restraint. The refrigerator hum is still there but it feels distant, like it knows better than to interrupt. Pipes settle into themselves. The street outside goes thin. Even the occasional car sounds temporary, like it doesn’t belong. Your screen becomes the loudest object in the room. Not visually. Psychologically. Ther...
