The part of the job AI keeps missing

There was a moment, sometime in 2023, when I started to feel it. Not panic, but a kind of alertness. The articles were everywhere. AI replacing engineers, entire roles becoming obsolete overnight. And there I was, managing a team of them. I was never particularly worried. I've always believed that the human element in building software, the judgment, the relationships, the context that lives betw...

Database Transactions: ACID Properties in Plain English

What Is a Transaction? A transaction is a group of database operations that either all succeed or all fail together. BEGIN; UPDATE accounts SET balance = balance - 100 WHERE id = 1; UPDATE accounts SET balance = balance + 100 WHERE id = 2; COMMIT; If the second update fails, the first one rolls back automatically. Money doesn't disappear into the void. ACID: The F...

How AI Scrapers Crashed My Vercel App (And How I Saved It with DigitalOcean & Cloudflare)

If you run a public-facing website today, you might have noticed some strange, massive spikes in your traffic. You get excited, thinking your app finally went viral—only to realize it's just AI bots hammering your servers. I recently experienced this exact scenario with my project, Viconic.dev, a platform for finding and sharing icons. Here's the story of how AI crawlers almost took down my site—...

Caching Strategies That Actually Work in Production

The Cache Taxonomy Not all caches are the same. Choosing the wrong one is worse than no cache at all. 1. In-Process Memory Cache Fastest possible. Zero network hops. Lives in your Node.js process. import NodeCache from 'node-cache'; const cache = new NodeCache({ stdTTL: 300, // 5 minutes default checkperiod: 60, // cleanup every 60s maxKeys: 1000, // prev...

Milla Jovovich just released an AI memory system. It reached over 1.5 million people and 5,400 GitHub stars in less than 24 hours.

Problem: None of the benchmark scores are real. Yesterday an X account belonging to a developer named Ben Sigman posted the launch of an open-source AI memory project called MemPalace. The post claimed "100% on LoCoMo" and "the first perfect score ever recorded on LongMemEval. 500/500 questions, every category at 100%." It credited the actress Milla Jovovich as a co-author. The GitHub a...

Optimistic Updates in React: UX That Feels Instant

Why Your UI Feels Slow User clicks 'Like'. Nothing happens for 300ms. Button finally changes state. That 300ms delay is your network round-trip. The server almost certainly succeeded. But the UI waited anyway. Optimistic updates flip this: assume success, update immediately, rollback if wrong. The Pattern // Before: wait for server async function likePost(postId: string...

The UK Must Choose Between Protecting Creators and Backing Big Tech in AI

A UK House of Lords report is urging the government to adopt a “licensing-first” approach to AI development, prioritizing copyright protections for creative industries over permissive data scraping practices. The report highlights economic risks to creators and challenges proposals for expanded data mining exceptions. While political pressure is mounting, the government’s pro-innovation stance sug...

"To Tag or Not to Tag is the Question" - Prince Hamlet Turning in His Grave

In communicator 1:1 chats, @mentioning someone is often unnecessary, yet many people do it out of habit, uncertainty about notifications, or to signal urgency. The problem is that tags can create avoidable “alarm” reactions, breaking focus and adding stress even when the message isn’t important. Over time, constant tagging inflates urgency and weakens the signal when something is truly critical. U...

Onboardly – Ask questions about any GitHub codebase

A few months ago, I asked HN about the biggest pain points when joining a new team (https://news.ycombinator.com/item?id=47368472). Most people said it was the tribal knowledge buried in the code. I've spent my time as a student building Onboardly to solve this. It’s a web app that indexes your GitHub repo and lets you ask questions in plain English. Unlike a general LLM, it cites the exact files ...
