How to Review AI-Generated Tests: Seven Checks Before You Keep Them

Review AI-generated tests with seven checks. Name the user risk. Break the product. Check the final result. Change the data. Read the failure. Repeat the run. Then decide whether the test could stop a bad release. AI can write a clean test in seconds. The file may look finished. The names may sound correct. The test may even pass. None of those facts prove value. A useful test catches a failure ...

My JetBrains Rider Setup for Surviving Live-Coding Demos

Hey lovely readers, If you've read any of my Public Speaking at Tech Events 101 blog posts, you already know I take demo prep very seriously. What I haven't written about yet is my IDE setup.

Your Date Picker Is Outdated. Here’s a Better Way.

Your Date Picker Is Outdated. Here’s a Better Way.

Most React apps still use the same old date picker. It works… but it feels clunky, especially on mobile. There’s a much better way: an iOS-style Wheel Picker. It scrolls smoothly, has that natural inertia feel, supports infinite looping, and just looks more polished. Users actually enjoy interacting with it. 😊 One of the best libraries for this right now is @ncdai/react-wheel-picker. It’s: ...

Why You Need Rate Limiting for MCP Servers (And How to Do It)

Why You Need Rate Limiting for MCP Servers (And How to Do It)

Without proper controls for how many times an Agent/LLM can hit an MCP Server, you open yourself up to potential DOS attacks, memory hogging, insane API bills, and server/system overload. Luckily, this can be mitigated quickly by rate-limiting the number of requests an Agent can make to an MCP Server. In this blog post, you'll learn how to implement rate limiting for MCP using agentgateway. ...

How to Generate OG Images at Scale: A Developer's Guide

How to Generate OG Images at Scale: A Developer's Guide The link preview is the first thing people see before they click. On X, LinkedIn, Slack, and iMessage, your URL renders as a 1200×630 card — and if that card is a generic gray box with your domain name, you've already lost the click to the person who posted a screenshot instead. Dynamic Open Graph images fix this. Instead of one s...

The Mindset Shift: Data Cleaning in Data Science vs. Data Engineering

I could have written about another tool I’ve picked up on my data engineering journey, but I found something a bit more fundamental. Recently, while exploring PySpark and building out a modular ETL pipeline, I caught myself looking at the data and asking: "Why am I cleaning this? How is this different from the normal cleaning I do in data science?🤔" I'd already spent plenty of time cleaning da...

Claude couldn't fix this CSS bug!

I have been working with Claude on a comments box section. Everything was good until I wanted to add a thread line to replies to give the users a better UX; then it couldn't do it correctly: either the thread line doesn't connect to the replies (image two), or it extends past the last reply (image one). I asked it to fix it over and over again, but it just seems to have gotten stuck! The rea...

The Shopkeeper Who Never Gets a Break

Walk into any small shop in India — a kirana store, a general store, a corner medical shop — and you'll notice something. The owner is doing five things at once. Weighing rice for one customer, answering "are you open on Sunday?" from another on the phone, mentally tracking that Ramesh still owes ₹200 from last week, and somewhere in there, trying to remember if they need to reorder sugar. None o...

I built 49 free online tools in 3 months — here's what I learned

I have a confession. Every time I needed to calculate my EMI, check my BMI, or figure out how many college classes I could skip — I'd Google it, land on some site plastered with ads, get asked to sign up, and then give up halfway. So I did what any frustrated developer does. I built my own. How It Started It started with one EMI calculator. Just a simple HTML page I made for myself to calcula...
