Documenting Automatic Backup as Observable States

Support becomes easier when “automatic backup” is represented as observable states instead of a boolean. The useful sequence is desktop ready, paired, automation enabled, same network, and one file received. State 1: trigger enabled Automatic Backup is a manual setting. Installing or pairing the apps does not enable it by itself. State 2: network qualified Automatic upload ...

TypeScript Enums Are Still Controversial in 2026: Here Is When to Use Them and When to Reach for `const` Objects

TypeScript Enums Are Still Controversial in 2026: Here Is When to Use Them and When to Reach for `const` Objects

TypeScript Enums Are Still Controversial in 2026: Here Is When to Use Them and When to Reach for const Objects This article was written with the assistance of AI, under human supervision and review. Most TypeScript enum debates stem from a single misunderstanding: developers treat enums as a pure type-level construct when they generate real runtime code. This disconnect creates bundl...

Tapo H100: Cellar Humidity Monitoring in Home Assistant

Cellars sweat. On a warm humid day the air you let in is warmer than the cold concrete, and the moment it touches a cold surface it gives up its water. That's condensation, and over enough summers it's how a basement grows mould in the corners you never look at. I wanted a number that warned me before that happened. The catch I already knew going in: a raw relative-humidity reading isn't that numb...

« J'ai fini le tuto Node, et là je suis bloqué » — le mur dont personne ne parle

Tu as fini le tuto. Le vrai, le gros, celui de douze heures. Tu as tout suivi, tout tapé, tout fait tourner. À la fin, l'application marchait. Tu t'es senti capable. Tu t'es dit : « ça y est, je sais faire une API ». Et puis tu as ouvert un dossier vide pour faire la tienne. Curseur qui clignote. index.js. Rien. Pas parce que tu as oublié la syntaxe. Tu la connais. Mais là, tout seul, sans que...

Instant Payments Risk Management: What Every Fintech Developer Should Know

The rise of instant payment networks has changed the way money moves. Transactions that once took hours—or even days—now settle in seconds. Whether it's FedNow, RTP, UPI, or other real-time payment systems, users expect payments to be fast, available 24/7, and completed almost instantly. For developers and fintech teams, however, speed creates a new challenge. When payments settle in real time, ...

Factory Method Design Pattern in Software Engineering: A Smarter Way to Create Objects

Introduction As software applications grow in size and complexity, managing object creation becomes challenging. Creating objects directly using constructors can result in tightly coupled code that is difficult to maintain and extend. The Factory Method Design Pattern solves this problem by separating object creation from object usage. It provides a flexible and reusable approach for creating obj...

Design First, Then Build: A Better AI Dev Workflow

The Scenario Every Developer Recognizes It is mid-2026, and you have a feature to ship. You open ChatGPT or Claude, type something like "build me a function that parses webhook payloads and routes them to the right handler," and wait. The model returns something plausible. You paste it in, run it, and it almost works. So you prompt again: "fix the edge case where the payload is missing ...

How Pokemon IVs Are Calculated Under the Hood — A Reverse Engineering Guide

If you've ever wondered whether that wild Pokemon you just caught has competitive potential, you've probably heard the term IVs (Individual Values) thrown around. IVs are the hidden genetics of every Pokemon — the 0–31 numbers baked into your Pokemon at birth that determine how strong it can ultimately become. But here's the thing: the game never tells you what your IVs are. You have to reverse-e...

I Built a Photo-to-Cross-Stitch Pattern Maker That Runs in Your Browser

Photo-to-cross-stitch conversion looks like a resizing problem. It is not. A pixelated preview can look convincing and still be frustrating to stitch. It may contain too many colors, lack readable symbols, provide no reliable dimensions, or become useless when printed. I built StitchFromPhoto to handle the practical part of that workflow. It turns an image into a counted cross-stitch chart in the...

Traceroute devlog #3

Most of this week's difficulty lived inside one single rule, and what made it worth writing about isn't any one fix — it's that I didn't actually understand the problem until I'd already "solved" it three times. The rule sounds small: if you click through a point on your own path that would carry you past your color's still-unreached endpoint, the path should stop right there and count as done. T...

Why Claude-generated screens are missing their states

Ask for a screen and you get the screen on its best day. Full of content, nothing loading, nothing failed, permission already granted, network fine. The product as it appears in a case study rather than as it appears on a Tuesday. This gets described as a limitation of the model. I think it's more specific than that, and the specificity is useful. It learned from portfolios Nearly eve...

LiveAvaBot Developer API: Embed Telegram Video Avatar Conversion in Your App

I built @liveavabot last year to fix a stupid problem: iPhone videos silently fail as Telegram video avatars. The bot has processed conversions for 290 users so far, and a few of them asked the same question: "can I hit this from my own code?" So I shipped a REST API. This post walks through the Telegram spec that makes video avatars weird, the ffmpeg pipeline that solves it, and how to call the ...

Getting Typed JSON Out of LLMs: Field Notes on generateObject

Headline: The Vercel AI SDK's generateObject is the reliable way to get typed, schema-validated JSON out of a language model: I pass a Zod schema, the SDK constrains the model and validates the result, and I get a typed object instead of hand-parsing a string that is JSON most of the time. Four things carried the weight for me — generateObject for one-shot extraction, streamObject for progressive...

Second, it needs to stamp out hundreds of clause objects fast without reconstructing them from scratch each time. Prototype and Factory Method are two classic Gang-of-Four cr...
