I Added Image Upload to an AI Product. The Hard Part Was Everything Around It.

I recently added an Image to Tattoo workflow to AIMakeTattoo. From the user’s perspective, the feature looks straightforward: Upload a photo or sketch. Choose a tattoo style. Adjust proportion and complexity. Generate a tattoo design. From the application’s perspective, image upload introduced a much larger set of concerns: multipart request parsing file validation image moderation anonymou...

Publish an agent run as a playable Story from GitHub Actions

Agent runs are usually reviewed as raw logs after the fact. That works for debugging, but it is weak for demos, release notes, and evaluation reviews: the useful part is the sequence of conflict, decision, action, evidence, and result. SunfishLoop now has a GitHub Marketplace Action for this workflow: it converts Codex, Claude Code, OpenClaw, JSONL, and plain LOG traces into a sanitized, playable...

Host Suspended Your Site for Malware? Do This

Originally published on the Bug Circuit blog. If your host suspended your site for malware, the fastest way back online is: get the exact scan report from your host, remove the malicious files (not just disable the infected plugin), rotate every password and secret key, update everything, run a clean third-party scan, and send your host proof of all of it before you ask for reinstatement. Skippin...

I tried to clone Google Docs, but ended up building a calmer writing app

Writely started as my attempt to build a simple Google Docs clone. But while working on it, I realised that copying more and more features would only create another crowded writing tool. So I changed the direction and focused on one idea: helping people write with fewer distractions. Writely is now a calm writing workspace with autosave, browser recovery, formatting tools, document export, and o...

Best CDN for Live Streaming in 2026: A Developer’s Guide to Choosing the Right Provider

TL;DR A live streaming CDN improves video delivery by serving content from edge servers closer to viewers. The best CDN depends on your audience location, latency requirements, streaming protocols, and operational needs. CDNetworks is a strong choice for global live streaming, especially when Asia-Pacific performance and ultra-low latency matter. Akamai excels at large-scale enterpri...

12 Signs Your Website Has Been Hacked

Originally published on the Bug Circuit blog. If your site shows a browser warning, redirects visitors somewhere strange, has admin accounts you didn't create, or your emails are suddenly bouncing, treat it as hacked until you've checked and ruled it out. None of these signs alone is proof, but two or more together is a strong signal. This is for any small business owner, freelancer, or agency r...

Answering a Security Questionnaire, No Security Team

Originally published on the Bug Circuit blog. A client's procurement or legal team just sent you a spreadsheet with 40 questions about penetration tests, vulnerability management, and encryption standards, and you're a two-person shop with no security team. Here's the short version. You don't need SOC 2 or an in-house security team to pass a vendor questionnaire — you need honest, specific answe...

How to Build an Embedded Linux Lab From Scratch

You do not need expensive equipment to build an embedded Linux lab. Start in QEMU with no hardware at all, then add one well-documented board and a 3.3V USB-to-serial adapter, then a logic analyzer, and finally a JTAG debugger only when a real problem needs one. Each stage builds a specific, practical skill, and spending in that order keeps you learning instead of shopping. Most people who want...

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...

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 ...
