Building a Browser-Based Sentence Counter with Local-First Text Processing

Many text utilities are simple enough to run entirely in the browser. A sentence counter is a good example. The browser already has everything it needs to accept text, analyze it, and display useful statistics. Sending the input to a remote server is often unnecessary. I built a small browser-based sentence counter as part of TextFixHub, a collection of free text utilities for everyday writing a...

Browser-based updates getting stuck on the "Confirm your admin email" screen — why Playwright stalls in wp-admin

On hosting environments without SSH access, the fallback is browser automation: Playwright logs into wp-admin and drives the plugin update screen directly. That works fine for months — until one day the script stops dead before it ever reaches the update screen. Note: Playwright is a browser automation tool. It reproduces clicks a human would make, but as code. What the "confirm your ...

Solon Validation: @Valid, 20+ Annotations, and Custom Validators Without the JSR 380 Baggage

I've been burned by JSR 380 enough times to appreciate a validation framework that doesn't drag in a whole ecosystem of dependencies. Solon's validation system lives in solon-security-validation — a single plugin that gives you 20+ annotations, entity validation, and custom validators, all without pulling in javax.validation or jakarta.validation. Let me walk through what I've found useful. ...

Why regex match highlighting breaks on nested capture groups (I found out the hard way building a tester)

I write enough regex that I got tired of bouncing between the browser console and random online testers just to check whether a pattern actually matched what I thought it matched. So I built a small one myself — text box, pattern box, live highlighting. I assumed the highlighting part would be the easy bit: find the match, slice the string at its start/end index, wrap that slice in a colored <s...

I built a tool that auto-drafts my overdue-invoice reminders (looking for 10 freelancers to test it free)

Hey everyone, Like a lot of you here, I freelance on the side — and the most awkward part was never the work. It was the "hey, did you get a chance to pay that invoice?" follow-up. I'd either say nothing (and not get paid), or write the email myself and feel like a jerk every time. So I built Invoice Chaser. How it works: Add overdue invoices (client, amount, due date) AI drafts reminder emai...

I Built an AI Assistant That Turns Natural-Language Ideas Into Stock Searches

Stock screeners are powerful, but they often require users to understand dozens of financial indicators and configure every filter manually. I wanted to make that process more conversational, so I built EasyStock. What does it do? You can describe the type of company you are looking for in plain English: Find profitable companies with manageable debt and improving momentum. EasySt...

One key, multiple models: picking a unified text-to-image generation API

Bottom line: if you're generating images from text and that work is one feature among twenty, put it behind a unified API where one key reaches multiple models, then pin the model id in config and move on. If the images are your product, integrate the vendor directly and pay for the extra key. I've shipped it both ways. The second way cost more than I budgeted. The search that lands people here ...

Urgent event notifications in Node.js: SMS first, email fallback, retry logic

If you just want the recommendation: send the SMS first, poll its delivery status yourself, and let your own timer — not the provider — decide when the email fallback goes out. For urgent event notifications from a Node.js service, that's the entire design. The retry logic is boring on purpose, and boring is what you want at 3am. I run a one-person SaaS. Every hour spent on notification plumbing ...

Limiting CPU Usage Using CPULimit

Limiting CPU Usage on Linux Processes Using CPULimit. In this tutorial, I will share a little bit about how to limit CPU usage on a process using cpulimit. I myself often use this tool when a process consumes an unreasonable amount of CPU. I once experienced a situation where, while using Burp Suite, the CPU usage on my laptop spiked to 100%. With a utility like cpulimit, it is certainly very help...

Solon Cache: Three Annotations, One Interface, and a Tags Trick You'll Use Every Day

I've been writing Solon for a while now, and one thing that surprised me early on was how clean the caching layer is. Not because it does anything revolutionary — it doesn't — but because it stays out of your way while still handling the edge cases you actually hit in production. Let me walk through what I've learned. The Three Annotations Solon gives you exactly three annotations for...

How to Generate Short Videos from Claude.ai with a Seedance MCP Connector

Sometimes the fastest way to prototype a video idea is not to open a separate generation dashboard, but to let your assistant create and poll the task while you stay in the conversation. This guide shows how the Seedance MCP connector works inside Claude.ai, based on the Ace Data Cloud documentation. The workflow is practical: add one remote MCP URL, authorize with OAuth, ask Claude to list avail...

Your Agent's Deadline Is a Correctness Test, Not an SLO

Ask an engineer to list their agent's failure modes and you'll hear about hallucinations, wrong tool calls, and bad JSON. Ask about time and you get a shrug. Yet the single most common thing a production agent does when it goes wrong is not fail loudly — it just takes too long. It loops. It retries a flaky tool. It waits on a model call that never streams a first token. And your eval suite, which ...

A league season is not a long tournament: four product bugs my test suite could never catch

I built a football prediction game for the 2026 World Cup. A month long, 104 matches, one winner at the end. It worked, people played, nothing caught fire. Then I pointed the same app at a domestic league: Ligue 1, 306 matches, 34 matchdays, nine months. Same data model, same scoring, same templates. Nothing crashed. Nothing threw. Every test stayed green. And almost every product decision insid...

Why I Validate Angular Compatibility Using the Published npm Package (Not the Source Code)

I just published a new article on a lesson I learned while maintaining my open-source Angular library. I used to validate compatibility against my workspace and dist/, but eventually realized that wasn't what developers actually install from npm. That led me to redesign the CI pipeline to validate the published package across multiple Angular versions instead. The article covers: Why testing ...
