The Test Framework Is Not the Product

A few years ago, the hardest part of building a browser test framework was getting started. You had to choose a runner, configure browsers, create page objects, wire up reporting, add retries, manage secrets, connect it to CI, and convince someone else on the team to learn how the whole thing worked. Today, you can open an AI assistant and ask it to generate most of that before lunch. That soun...

Nine Months of Nagging, Zero Reading

🦄 I shipped a linter that fails your commit if you won't admit AI touched the code, and then did the most predictable thing possible—let nine months of the data sit there untouched while I busied myself with other things. Then I actually looked at it: nine months of footers piled up in git log like a lonely change jar. Every one of them said how much of those commits were mine, but I hadn't ever...

AI Coding Agents Don't Understand APIs. They Memorize Them.

We've all had the same experience. You ask your coding agent to integrate with a new platform. It confidently writes code. It references endpoints that don't exist anymore. It misses required headers. It mixes API versions. It hallucinates authentication flows. None of this is surprising. Large language models don't "know" an API. They know about an API from their training data. Even when ...

One OpenAI-Compatible Endpoint for Multiple LLM Providers: A Practical Setup Guide

When an application starts using more than one language model provider, the hard part is rarely the first API call. The hard part is everything that follows: separate credentials, different request shapes, provider-specific errors, billing dashboards, and model migrations scattered across the codebase. A useful way to reduce that surface area is to keep one OpenAI-compatible client contract and m...

The Rusty Hobbit: Ownership System Explained for JavaScript Developers

The Quest Begins (The "Why") Hey friend, picture this: you’re happily writing a Node.js service, passing objects around like they’re candy at a parade. Everything works until one day you mutate a shared object in a helper function and suddenly your UI shows stale data, or worse, you get a mysterious Cannot read property 'map' of undefined that only appears in production. You spend hours...

Vael-ui - Vapor Ready Vue Components

Vael-ui - Vapor Ready Vue Components

In the past few weeks I've seen a LOT of UI libraries on this sub, so I thought I'd throw my hat in the ring too. I built vael-ui.dev (yes... vael was already taken), the first Vue Vapor component library! Vapor API is 1:1 with the VDOM components. If you want to switch rendering modes, it's literally just an import swap. import { createVaporApp } from 'vue' const app = createVaporApp(App) ...

Passkeys Explained Simply

You’ve probably seen that little prompt that says “Sign in with Face ID” or “Use a passkey” instead of the traditional password field. That’s a passkey. And no, it’s not just a password hidden behind your fingerprint. The best password is the one you never have to type. The Problem with Passwords A password is a secret that you have to remember, and that the website has to store (id...

Why We Run Every AI Pipeline in Its Own Process

The runtime boundary behind RocketRide's crash isolation, task lifecycle, and Cloud operations. By Krish Garg and Mithilesh Gaurihar At 9 a.m., with ten thousand users mid-session, a node in an AI pipeline dereferences a bad pointer. The process running it is gone before Python can raise a useful exception. That is an unpleasant failure, but it is not the question we care about most. The questi...

The SEO advice of the past ten years doesn't work the way it used to

I still remember the spreadsheet. Keyword, search volume, difficulty score. Pick the keyword, hit the target density, write the meta description, done. I built entire client strategies around that sheet for years, and it worked well enough that I never questioned it too hard. I opened an old version of that spreadsheet last month while helping a client plan content for the fall. Half the columns ...

Technical interview coaching?

Not looking for one-off mock interviews. I want someone who can assess where I'm actually at, build a personalized plan, and work with me over time until I feel genuinely confident going into a high-stakes interview. I have 7 years of experience, but interviews still make me very anxious. What always worked for me in high school and college was one-on-one tutoring, and I'm hoping to find that same...

Ego-Lite: The Open-Source Browser Built for Humans and AI Agents

Parallel Web Automation: Meet Ego-Lite AI coding agents are increasingly taking on web-based tasks—such as filing bug reports, checking deployment dashboards, and scraping documentation. However, traditional browsers were built strictly for human interaction. When an AI agent automates Chrome via Playwright or Selenium, it often steals focus, moves your mouse, or requires complex logi...

The most-starred LLM trading paper claims buy-and-hold lost 5.23%. It actually gained 9.12%.

falsify-ledger.* TradingAgents (arXiv:2412.20138, ~94,700 GitHub stars) is probably the most visible "LLM agents trade stocks" project right now. The headline result: a multi-agent LLM framework earned a 26.62% cumulative return on AAPL with a Sharpe ratio of 8.21 between 2024-06-19 and 2024-11-19, while buy-and-hold supposedly lost 5.23% over the same window. That last number takes one API call...

AI Changes the Tools, Not the Fundamentals

This may sound counterintuitive, but in the era of AI, less is more. AI can help anyone write code faster, but it can't replace an understanding of how production systems actually work. The competitive advantage isn't knowing more tools—it's understanding the fundamentals that every production application is built on. Mastering those fundamentals may be the way to do more with less. Every good ba...

Usando o Claude como um recrutador técnico pessoal para encontrar minha próxima vaga

Todo fim de tarde era a mesma rotina: abrir o Indeed, digitar "desenvolvedor PHP", rolar dezenas de resultados quase idênticos, abrir cinco ou seis em novas abas, ler a descrição, comparar mentalmente com meu currículo e, na maioria das vezes, fechar a aba sem me candidatar porque "não parecia ...

My LLM Kept Making Stuff Up on Resumes. Here’s How I Shut It Down.

I'm building NextStep — an AI thing that scores your resume against a job and rewrites it to fit. Two features, both completely dependent on the model not lying. And GPT-4o loves to lie. Two bugs made me stop trusting it: Score the same resume twice → 87, then 79. Cool, so the number means nothing. Ask it to "optimize for this DevOps role" → it adds "Managed production Kubernetes clusters" to a ...
