How I Built a Privacy-First Browser Game Portal with Click-to-Load Iframes

Embedding a browser game looks simple: <iframe src="https://games.example.net/my-game"></iframe> That line lets a third party join the page lifecycle immediately. It can download a large bundle, establish connections, run scripts, request storage, display advertising, or fail before the visitor decides to play. AI-assistance disclosure: I used AI to help draft and edit this ...

Working with Let's Encrypt's Short-Lived tlsserver and shortlived Profile Certificates

Let's Encrypt issues TLS certificates with a 90-day validity period by default. However, as the industry is gradually shortening TLS certificate lifetimes—with the maximum eventually expected to fall to 47 days—Let's Encrypt already offers certificates using the tlsserver profile with a validity period of 45 days. Compared with the current default classic profile, the tlsserver profile removes de...

I Built a Blood Donation Management System with the MERN Stack

Every year, thousands of people struggle to find blood donors during emergencies. I wanted to build something that could simplify that process while improving my full-stack development skills. So I built a Blood Donation Management System using the MERN Stack. The goal was simple: create a platform where donors, recipients, and volunteers can connect efficiently through a modern web application....

Testing AI Coding Agents Beyond Code Generation: A Real-World Benchmark

1. Introduction Most public demonstrations of AI coding agents begin with an empty directory and end when a visible feature works. That is useful, but it measures only the first and easiest part of software engineering: generation. Real projects are stateful. They contain existing behavior, data that must survive, security boundaries, partially completed work, and verification steps tha...

I gave an AI agent a business and $0. It found the one thing AI can't sell.

I set up Claude Code to run a business autonomously. Its own memory directory, a decision log, a world-model file. Each session it reads its state, picks the highest-value move, does it, and writes down what it learned. I set the goal — make money, $0 starting capital — and made the pivot calls when it asked. It did the work. Thirty-one sessions later it has earned exactly $0.00. That's not the ...

The Python import that silently disabled a feature for months

I was reading an open-source instrument-control library to add docstrings — a boring job, deliberately. Boring jobs make you read code you'd otherwise skim. About two hundred lines into one function I found a caching feature that had never worked. Not "worked badly." Never executed successfully, not once, and never left a trace of failing. Here's the shape of it, reduced to the part that matters...

You Deleted BM25 the Day You Bought a Vector Database. Your Fraud Queue Noticed

BM25 is a ranking function from the 90s. No GPU, no embedding API, no per-token bill. And in a fraud operation it still wins half the queries — because fraud analysts don't search in prose. They search in identifiers. Watch a fraud analyst's search history for a day: decline code 4863. Rule VEL-013. BIN 529904. Promo code FIRSTBUY20. Order #48213. These aren't concepts. They're strings — and "sem...

I miss when development was actually solving problems

Lately I've been having thoughts about what the point is. Back in the day when I got into programming, I just wanted to make cool things. I made a lot of cool things. They took time so I knew they were genuinely either unique, special, or in any other case, mine. I made twitter/reddit/discord bots, data visualizations for social media platforms, and useful tools for my communities I was involved i...

So you go looking, and every guide hands you the same shape: a public DNS record, ports 80 and 443 open to the entire internet, a reverse proxy, a certificate, and a login page that anyone on earth can now knock on.

How I Built 6 Game Wiki Sites in 30 Days with Astro

I love playing video games, but I kept running into the same problem: every time a new game drops, the existing wiki sites are slow, bloated with ads, or just missing key info. So I decided to fix it myself. Over the past month, I built 6 lightweight game guide sites using Astro. Each one focuses on a single game — no clutter, no ad spam, just the info you actually need when you're stuck on a...

Close your editor before heavy jobs? The heavy job lives inside my editor

I run an automated video pipeline that generates images locally, on my Mac. A 16GB M4. The image model is FLUX, a 12B-parameter thing that keeps ~7GB of weights resident in memory even quantized down to 4bit. I've frozen this machine before (lesson learned the hard way), so there are safety mechanisms in place. A pre-flight gate: don't even start generating if free memory is below 50%. And a watc...

SnowLens: Free Snowflake Observability — 9 Detectors, Zero Data Egress

If you run Snowflake in production, you've probably asked yourself: which queries are burning credits? Why did costs spike last Tuesday? Are any warehouses just sitting there idle? Most observability tools answer these questions by shipping your query logs to an external SaaS — data egress, vendor lock-in, another subscription. SnowLens takes a different approach: it's a Streamlit app that instal...
