AI built your codebase in 2 months. Who's going to maintain it?

Cloudflare shipped EmDash in April 2026 — an open-source CMS written in TypeScript, built in ~2 months by AI coding agents. It's a genuinely impressive achievement and a real signal of where the industry is going. But it also surfaces a question that the AI coding conversation has been avoiding: what happens after the AI ships the first version? The "plans that read well don't build wel...

I built a Shopify app that makes stores feel instant using link prefetching

I've been building small Shopify apps as side projects for a while, and one thing that's always bugged me about Shopify stores is the noticeable page load delay when navigating between products and pages. You click a link, and there's a brief but annoying pause before anything happens. It's not catastrophic, but that friction adds up — especially on mobile connections. I decided to fix it. ...

Thunder Client Pro Paywall: What Changed and Your Best Alternatives

TL;DR Thunder Client has moved git sync—saving your collections as JSON files in your project—behind a Pro paywall. Free users can still send requests, but collections are now stored in VS Code's extension storage, not in your project or git. Your best free alternatives: REST Client (file-based, git-friendly), Apidog (cloud sync, free workspace), or sticking with an old Thunder Client v...

The Freelance Rate Formula I Wish I Knew Earlier (Free Calculator Included)

Most freelancers undercharge. Not because they're bad at business — but because they don't have a systematic way to calculate what they actually need to earn. Here's the problem: when you don't know your minimum viable rate, you either charge too low (and burn out working too much) or too high (and lose opportunities you should've won). The Basic Formula Your freelance rate should cov...

The Future of Voice AI in Banking: Amar Kant Jha

Amar Kant Jha outlines how voice AI is transforming banking through conversational interfaces powered by hybrid edge-cloud systems. Success depends on low latency, multimodal UX, and strict security—like device-bound authentication and exactly-once processing. Banks must balance usability with compliance, ensuring privacy, reliability, and scalable AI deployment in regulated environments.

Automated Intelligence Dev Bounty Scouter with OpenClaw, Gemini & SearXNG in RPi

This is a submission for the OpenClaw Challenge. What I Built Following up on my previous exploration in Self-Healing Dev Bounty Hunter with OpenClaw, I realized that total AI autonomy can sometimes be a trap. If you let an agent run completely unchecked, you end up hoarding garbage data. To solve this, I expanded the architecture into an Automated Intelligence Dev Bounty Scouter. Kh...

GDPR Erasure Is Not DELETE FROM users

When a parent on our school platform submits a deletion request, an administrator approves it, and our server runs one function — anonymiseContact($contactId). That function took five attempts to get right. This post is about what makes Article 17 of the GDPR (the "right to erasure") genuinely difficult to implement, the decision tree we eventually settled on, and the specific failure modes we hi...

AI monetization strategy: Pricing models for AI systems

AI has changed how software generates value and how it incurs cost. AI businesses must contend with unpredictable compute expenses, non-deterministic workloads, and rapidly shifting infrastructure. And as AI moves from simple assistance toward full autonomy, traditional billing assumptions no longer hold. This article explores how AI reshapes software economics and examines pricing strategies tha...

Why Every Developer Should Care About Platform Architecture in 2026

Why Every Developer Should Care About Platform Architecture in 2026

I've had this conversation too many times. A developer joins a project, looks at the architecture, and says some version of 'who made these decisions?' It's never one catastrophic choice. It's a dozen reasonable-at-the-time decisions that compounded into something that's genuinely painful to work in. Platform architecture isn't glamorous. Nobody puts it in their portfolio. But getting it wrong is...

Using Claude API to Generate Structured Product Comparisons at Scale

Here's how we do it in a way that produces accurate, useful content rather than filler. Why ...

Its media distribution has evolved from simple static MP4 links to a sophisticated Dynamic Adaptive Streaming (DASH/HLS) architecture. For many users and creators, archiving high-quality content from X is a necessity, yet the technical barr...

Why Your API Contract Breaks in Production (And How to Fix It in the Spec)

The most expensive API bugs I've seen weren't implementation bugs. They were contract bugs — cases where the producer and consumer had different beliefs about what the API promised, and nobody wrote it down before the code was shipped. Here's the pattern: a team builds an endpoint, the frontend and backend agree on the behavior in a Slack thread or a meeting, and the implementation proceeds. Six ...
