To get started with competitive Pokémon battles, all you need is your phone. But to compete at the highest level, like at the Pokémon World Championships, you're going to need a Switch. And there doesn't seem to be a good reason why. Battle simulator Pokémon Champions originally launched on the Switch and Switch 2 in […]

The Fairphone 6 Plus feels like an extremely average midrange Android phone and I couldn't be more thrilled. The mission has always been admirable. Fairphone seeks out ethically sourced materials and offers a high degree of repairability for its devices. But the phones themselves required a lot of sacrifices, like putting up with underpowered processors […]

A random game is easier to debug when the same inputs produce the same result. In HoopTrait, a browser basketball project, the Lab mode combines eight selected traits and generates a fictional career. The interesting engineering problem is keeping replay, sharing and validation consistent. This is a technical development note, not a claim that a game score predicts an athlete's real performance. Store the decisions, not just the result The Lab state records a seed, a dataset v...

The bill that started this I was paying $40/month for a PDF generation API to power a tiny internal invoicing tool for a client project. Forty bucks a month to convert some JSON into a PDF. That's it. That's the whole service. I finally sat down on a Saturday to see if I could kill that subscription. Three weekends later, not only did I kill it — the replacement is faster than the API ever was, because there's no network round-trip at all. This post is the log of how it went, in the or...

DevTools responsive mode has one limitation that's never been fixed: you see one device at a time. You check iPhone. Looks fine. Switch to iPad. Fix padding. Switch back to iPhone. Was the header already broken or did you just break it? I got tired of holding layouts in my head, so I built a tool that shows all three at once. Responsive Tool — free, no signup Paste a URL → phone, tablet, and desktop load at one time. That's it. A few things that make it actually...

Humanistic Architecture Learning to See Problems Differently I had the opportunity to attend a class called “Humanistic Architecture” by Mr. Chakrit Riddhagni. The class was about applying humanistic principles to software development . Before talking about what I learned, I would like to share a little about my own perspective on software development. Personally, I have a quote and a belief about software development: it is both a science and an art. I see software developm...

I rent six dedicated servers from a company in Germany. Together they have more cores, more memory, and more SSD than most production clusters I worked on a decade ago. I run my own Kubernetes on them. Not managed. Not EKS. Not GKE. The whole stack, from the immutable OS up to the workloads. People who hear this ask me why, and the question usually arrives in one of two tones. The dangerous tone is "that's amazing, how do I do it" . The responsible tone is "why on earth would you do that...

I'm 12 years old. I build websites and full-stack apps. And recently, I decided to test something I've never seriously tried before: Can I actually make money from coding? Not from ads. Not from selling a course. Not from some complicated SaaS business model. Just by making a simple website for a local business. So I started looking for businesses that could use a better online presence. And then I sent my first message. The idea I noticed that a lot of local bus...

Give me read access to a $50,000/month AWS account and I will tell you within a day where the first 20-30% is hiding, because on a mid-size bill it is almost always hiding in the same four places, in the same order: data transfer you can't see in the console, instances sized for a load test that ran two years ago, on-demand pricing on a baseline that never moves, and storage rotting in the most expensive class AWS sells. None of this needs an architecture rewrite. AWS cost optimization, at least...

If your AWS bill has a NAT Gateway line, you are paying twice for the same packet: once for the gateway to merely exist, and again for every gigabyte it carries. The fix for most teams is dull and free. Add an S3 and a DynamoDB gateway endpoint, route the heavy traffic away from NAT, and only then argue about anything fancier. That single change is free to turn on, takes minutes, and stops the most expensive traffic from ever touching the meter. This is a playbook, not a lecture. The trick wi...

For AWS Savings Plans vs Reserved Instances, the default answer is: buy a Savings Plan, not a Reserved Instance. The exception is OpenSearch, Redshift, and (until December 2025) databases, which still need the older Reserved model. That is the whole decision. For most teams a Compute Savings Plan is the right default: same discount as a Convertible Reserved Instance, far less to manage, and it follows your workload across instance families, regions, Fargate, and Lambda. The cases where a Reserve...

Most S3 bills are wrong, and the fix takes an afternoon. The data sits in the most expensive class AWS offers (S3 Standard, $0.023/GB-month), nobody set a lifecycle policy, incomplete multipart uploads are silently billing for storage you can't even see in the console, and every byte your EC2 fleet pulls from S3 is routed out through a NAT Gateway when a free VPC Gateway Endpoint would do the same job for $0. None of this needs an architecture rewrite. It needs a checklist run in the right order...

The cloud bill is the only number in most companies that nobody on the team owns until it's already a problem. Engineering owns latency. It owns error rates, p99, uptime, the whole observability wall. Finance owns the invoice. And between those two ownerships there's a gap wide enough to drive a fifth to a third of your cloud spend straight into a wall — which, across the industry, is roughly what happens. The fix isn't a smarter spreadsheet at month-end. Real cloud cost management isn't an a...

I had four small services. Each one was a Model Context Protocol adapter — a thin wrapper that lets an AI agent call out to some external thing. One talked to Replicate for image generation. One talked to a Nostr-friendly social poster. One was a Git-aware research helper. One was a Tavily-powered web search. They were all written in Python. They all ran on Knative on a small Kubernetes cluster. They all worked. And they were all just slightly too slow to use. A six-second cold start is ...

Polls show that overwhelming majorities of Americans hate data centers. China makes a perfect scapegoat for tech leaders and their allies—the only problem is a lack of evidence.
