Stop apologising for using AI

Stop apologising for using AI How long do you think it'll be until we stop saying "with 's help" or "I wrote this with " as if it's a bad thing? Let's admit it, if you aren't using AI in some way in your job, you're one of the very few. Take my recent code contributions to H5YR.com. Every single one of them is coauthored by me and Claude. Is that something I should be hiding? Or apologising for? I feel like we, as developers, are almost guilty that we're no longer handwriting code, so ...

Real-Time Collaboration with Socket.IO: How to Sync Drawing Events Across Multiple Users

Introduction Imagine two developers working on the same whiteboard from different locations. When one person draws a shape, the other should see it almost immediately without refreshing the page. This is a real-time collaboration problem. It requires more than drawing on a canvas: the application must capture user actions, communicate changes to a server, and deliver those changes to the correct connected clients. In this tutorial, we will explore how Socket.IO can help build the commu...

Finding European manufacturers with VAT IDs: a sourcing workflow with Europages data

When you need a manufacturer in Europe (a private-label cosmetics lab, a CNC machining subcontractor in Poland, an olive-oil producer in Spain), you usually start on Europages . It lists over 3 million companies, and they fill in their own profiles: products, employee count, founding year, sales area, and often their VAT number, payment terms and incoterms . The problem is the interface. You click through 30 results per page, open each profile, and copy fields into a spreadsheet by hand. ...

Hyperliquid Testnet Quickstart: Test Funds, a First Order and 5 Mainnet Gotchas

A condensed version of our full Hyperliquid testnet guide , which also covers HyperEVM gas, every error message we hit and a pre-mainnet checklist. Hyperliquid's testnet lets you trade with mock USDC, so you can test order logic and signing before real money is involved. This is the short path: the addresses, test funds, one working order, and the five things that will break when you switch to mainnet. 1. The addresses you need What Testnet Mainnet API (...

Build and publish a docs site for your project with Thally, from an empty folder to a live URL

I documented a small open-source app, Quiz Tracker , with Thally and published it at https://quiz-tracker.thally.app . This is the path I took, including what broke along the way and how I got past each problem. You can follow it for any project that has a README and, optionally, an API. The finished source is at SECHUBSYSTEM/quiz-tracker-docs . What you'll build A docs site with an introduction, a quickstart, one task guide, and an API reference generated from an OpenA...

GitHub's Copilot default policy is enforcing itself through October 26: what to check before it chooses for you

On October 22 GitHub started enforcing the global default policy for generally available Copilot features. The rollout runs through October 26 and lands at different times for different enterprises and organizations. Anything eligible that your org never explicitly configured gets set to whatever that default says. For a lot of teams this means features switching on, or off, with nobody clicking anything. This is the kind of change that turns into a mystery incident three weeks later: an agen...

When 9.75 becomes 975: what silently breaks in browser-side invoice OCR

We ran a real invoice through our own converter and opened the export in Excel. The date on the page read 11/02/2019 . The cell said 1110212019 . The total was 9.75 . The cell said 975 . And Invoice Total $204.75 , the one line a bookkeeper actually needs, was not in the file at all. That row did not exist. Nothing errored. No red toast, no console warning. The file opened cleanly in Excel, the columns were aligned, and every number looked like a number. Which is the worst possible fa...

Preventing Race Conditions in Inventory Management Using Database Transactions

Introduction Inventory management looks simple at first: check how many items are available, confirm an order, and reduce the stock. But what happens when two customers try to purchase the last item at exactly the same time? If both requests read the same stock value before either request updates it, the application may accept both orders even though only one item was available. This is a classic example of a race condition. In this tutorial, we will explore why this happens and how...

How to Stream Claude Agent Events with Kinesis Data Streams, Explained Simply

Real‑time LLM interactions feel like they belong on websockets, but a Kinesis Data Stream gives you durable, auto‑scaling fan‑out with millisecond latency. In this guide you’ll see how to pipe Claude’s token stream through Kinesis and a Node.js 22 Lambda, turning a flaky WebSocket demo into an enterprise‑grade pipeline. Why Kinesis Beats WebSockets for LLM Streams When you ask Claude for a response, the model sends back tokens (tiny pieces of text) as they are generated. A WebS...

DawnPatch: Let Your Laptop Reproduce the Bug Before You Touch the Code

This is a submission for the Hacktoberfest Open-Source AI Challenge Week 3: Slow and Steady .* What I Built The part of fixing a website bug that I keep putting off is getting everything into one place: the reproduction steps, the failing screen, the relevant source, the proposed change, and proof that it helped. I built DawnPatch , a local maintainer workbench that turns that process into a reviewable investigation. Give it an authorized local repository, an issue, and b...

Below Grade, Above the Grid: Georeferencing a Grand Central Madison Model

The first model looked convincing and was wrong by about forty meters. The station sat under the right avenue at roughly the right depth, but when I laid a street map over it, the entrances landed on the wrong blocks. The mesh was fine. The reference frame was not. That is the step map-to-3D work tends to skip. A generated scene can look correct alone and still be useless for measurement, sections, or overlays. Before adding an escalator, I had to decide where the model was, what zero meant, an...

Free Google Maps Leads Into a Spreadsheet: I Had Claude Build the Scraper

TL;DR: I wanted business leads without paying for a lead database. So I had Claude (running inside VS Code) build a small program on the Google Places API that searches one niche in one location and writes the results into a Google Sheet. I tested it live on plumbers in Italy. The first pass returned company names and websites but no emails. A second prompt got emails plus notes on mistakes on each site, like placeholder text left in a homepage carousel. I didn't send any emails in this run, so...
