Soft Skills Summarize Part 2

Why is this book unlike any other book you've read? The author begins the first chapter with this question, saying that most books related to software development are about software development, but this book is not like that; it is not just about software development, but about making you a good developer. By “good” he means that you will not only be excellent at solving software prob...

One Telegram Tap, Three Platforms Live

I type one idea into Telegram. A few seconds later I get back a short post and a full article, both drafted from that single idea. I read them, tap approve, and they go live. That's Content Factory, the tool I'm building right now. The bot is not creative on its own Content Factory isn't trained on my old posts and it hasn't learned my style from some dataset. All the voice and struct...

React use() cache gets overwritten by an older Promise after invalidation

I am using React 19.2 with Vite. I am playing around with a small Promise cache for React 19 use() and I cannot figure out the best way to handle this. So I start with one request and it takes 1.5 seconds. Before it finishes I delete the cache entry, change the value from Nicole to David and trigger another render. The second request finishes first and puts David in the cache (which is what I want...

Three Sui Exploits, One Disease — Why "The Math Looked Fine" Keeps Costing Hundreds of Millions

Cetus lost $223M to a shift overflow. Aftermath lost $1.14M to a negative fee. Bucket Protocol ships a decimal scaling bug today. All three passed audits. All three have the same root cause. I've spent the last month reading exploit post-mortems, scanning production Sui contracts, and building lint rules to catch what I kept seeing. After the third time the same shape showed up, I stopped thin...

Four lessons from building AI, education, and healthcare products with Next.js

Over the last few years, I have built products in very different domains: generative AI, job search, education, and clinic operations. Although the interfaces and users are different, several engineering lessons appeared repeatedly. 1. Multiple AI features still need to feel like one product Klyro brings together streamed chat, cited web search, image analysis, and image generation. ...

The ten-line binary search that balanced a four-million-item crawl

A short field note. I had to crawl every item in a public registry (~4 million of them) in about a day. One idea did most of the work. The problem Split the sorted keyspace into N ranges, run one worker per range, done. That's the plan. It falls apart because keys aren't uniformly distributed. Cut the alphabet into even chunks and one chunk swallows all the dense prefixes while the ...

The rollback endpoint took a deployment ID and did nothing with it

This is a submission for DEV's Summer Bug Smash: Clear the Lineup powered by Sentry. Project Overview Staxa is a multi-tenant deployment platform I am building solo under Stackforge Labs. The backend is a single Go binary (staxad) using the chi router, with about 60 API endpoints, running on K3s on a Hetzner CAX21 ARM64 server that costs around $11/month.

The five primitives I run a whole company on

I run a consumer product company by myself. Physical inventory, two storefronts, multiple marketplaces, subscription billing, bookkeeping, tax filings, government paperwork, content in two languages, and a codebase that ships to production most weeks. Headcount: one. Not "one plus a virtual assistant." One. Three years ago this was not possible. It is also not possible today by keeping a chat win...

I Replaced ESLint and Prettier with Biome

I used to juggle ESLint and Prettier every day. Two tools. Multiple config files. Plugin conflicts. Slow checks. And that constant feeling that something was always fighting something else. Then I found Biome. Biome is a single, Rust-powered tool that does both formatting and linting. It replaces the classic ESLint + Prettier combo with one binary and one simple config. Why it feels differen...
