How I Used AI to Build an 80s-Style Game in a Few Days

Intro An AWS Summit booth. A retro game. A LEGO Game Boy as the prize. That's basically the brief my company gave us for an internal contest called the "INO INO Gameboy Challenge": build a simple, 80s-style game that people can play in 10–30 seconds at the stand, with AI tools fully allowed and even encouraged. I couldn't say no to that. In this post I'll walk through how I'm designing ...

I Ran Every Meeting Async for 30 Days. Here's What Actually Happened.

For 30 days, I replaced all team meetings with async updates. No standups, no planning sessions, no "quick syncs." Here's what I learned. The Setup My team was three people, distributed across two time zones. We had: Daily standup: 15-20 minutes Weekly planning: 45 minutes Biweekly review: 30 minutes Various "quick calls" that were never quick Total: roughly 5-7 hours per week in m...

Understanding Subqueries vs CTEs in SQL (With Examples)

When working with SQL, especially in data analysis, you’ll often need to break down complex queries into manageable pieces. Two powerful tools that help with this are subqueries and Common Table Expressions (CTEs). This article explains what they are, how they differ, and when to use each—using clear examples. What is a Subquery? A subquery is simply a query nested inside another SQL query. It ...

Building a Multi-Agent AI Swarm with Valkey as the Nervous System

Building a Multi-Agent AI Swarm with Valkey as the Nervous System

AI agents need more than model calls. They need memory, coordination, and deterministic state transitions. In this project, we built NeuroValkey Agents: a 3-agent Node.js swarm where Valkey is not a cache, but the central runtime substrate for orchestration. Agent 1 (Researcher) generates facts and stores vector memory. Agent 2 (Writer) retrieves semantic context with KNN search and drafts summ...

Software Architecture as Educated Coarse-Graining

Every serious practitioner agrees that software architecture matters. Almost nobody agrees on what the word means. That's an operational problem disguised as philosophical nuisance. If you can't define what counts as architectural, you can't scope an architecture review, you can't decide what belongs in an ADR, and you can't tell a junior engineer why their "small refactor" just changed the system...

Vibe coding vs. spec-driven – I got the bill

There is that moment at the beginning of a new feature where everything is still open. No legacy code, no constraints, no unexpected dependencies. Just you, an empty directory and an AI tool that promises to deliver results in minutes. In moments like that, vibe coding is incredibly tempting. Just start. Prompt in, code out, next prompt. No planning, no specifying, no thinking about architecture....

Beyond the "Vibe": Why we need to treat AI assets as Infrastructure, not just Outputs

We’ve all seen the "Vibe Coding" debates recently. It’s a polarizing term, but it points to a very real shift in how we’re building. However, while we’re busy refactoring our agentic workflows and pruning terminal noise, there’s a massive "Execution Gap" lurking in a place developers rarely like to look: Creative Assets. For the last year, building Pixizen, I’ve been obsessed with a single proble...

SpaceX 600亿美元收购 Cursor 的同一天，我悄悄把 AI 编辑器换成了免费的它

SpaceX 600亿美元收购 Cursor 的同一天，我悄悄把 AI 编辑器换成了免费的它 核心结论： Cursor 月费20美元，而 Codeium 出品的 Windsurf 功能几乎相同——完全免费。本周我用它干了2周的生产项目，发现了8个被全网忽略的隐藏用法。 当你还在为 Cursor 每月掏20美元时，有一群开发者已经发现了真相：Codeium 旗下的 Windsurf，100% 免费，却藏着连付费工具都没有的杀手级功能。 本周最爆炸的新闻：SpaceX 以 600亿美元收购 Cursor。这条新闻让整个 AI 代码编辑器赛道沸腾了。但沸腾背后，有一个事实被忽略了——Windsurf 已经在暗处卷了很久。 💡 很多中文开发者只知道 Cursor、Windsurf 名字听说过，但没深入用过。今天这篇，带你挖透它被忽视的硬核功能。 ...

Color Contrast Failures: The Number One Accessibility Issue and How to Fix It

Color contrast failures are the single most common accessibility issue on the web. The WebAIM Million study found them on 83.6% of home pages tested. Yet they're also one of the easiest issues to fix — once you understand the rules. The WCAG Contrast Requirements WCAG 2.2 defines two success criteria for color contrast: 1.4.3 Contrast (Minimum) — Level AA Normal text (< 18pt or &...

I Built a Swarm Agent RAG System Inspired by Karpathy's LLM Wiki

Most RAG systems use a single retriever to search a vector database. It works — until your knowledge base has code, images, tables, and text all mixed together. One retriever can't specialize in all of them. So I built rag-swarm — a multimodal RAG system where specialized swarm agents search in parallel, and an LLM-powered oracle evaluates every result before it reaches the user. The architectur...

TLS Certificate Expiry: Detection, Renewal, and the 47-Day Future

The cert expired on a Saturday at 02:14 UTC — not a Tuesday, not during business hours. That's when I learned our paging rotation had a gap between outgoing and incoming on-calls. By the time we deployed a valid cert, we'd lost 97 minutes of checkout traffic and two SOC 2 evidence items. TLS certificate expiry is the most predictable outage in production infrastructure, and it's about to get 8x no...

AI made devs feel 20% faster but measured 19% slower. Nobody's ready for that conversation.

AI tools made developers feel 20% faster. Then researchers measured them at 19% slower. Read that again. That's not a rounding error. That's a 39-percentage-point gap between perception and reality. And nobody in this industry wants to talk about it. The Study That Should Make You Uncomfortable The METR study used a randomized controlled trial. Not a survey. Not a blog post. Not a ven...

n8n Execute Command Node vs. FFmpeg API: Why Cloud Users Are Switching

Originally published at ffmpeg-micro.com. You built a video processing workflow in n8n using the Execute Command node. It worked on your laptop. Then you deployed to n8n Cloud and nothing happened. That's because n8n Cloud doesn't include FFmpeg. And even if you're self-hosting, the Execute Command node is disabled by default since n8n v2.0 for security reasons. You can re-enable it, but now you...

Claude Code vs Cursor vs Windsurf: I Used All Three for 2 Weeks, Here's My Honest Take

Same tasks. Same codebase. Three tools. Two weeks. One developer who got increasingly opinionated. I want to start with an admission. I went into this comparison expecting Cursor to win. I've been using it for eight months, I know its quirks and I've got my keybindings dialled in. Trying two other tools for two weeks felt like the kind of exercise that confirms what you already believe. That's ...

🔔 Small productivity hack that's changed how I work with Claude Code

I typically have half a dozen Claude Code sessions running at once, spread across different terminals and monitors, some hidden behind other windows. The visual "done" indicator is easy to miss when you're not looking at the right terminal. About a month ago I added a global hook that plays a short chime whenever any session finishes a task. Two minutes to configure. Can't live without it now. T...
