Here's a glimpse of how software engineering is going to look soon. I wanted to spend more time with my newborn daughter and less time sitting in a terminal watching an AI type. So I built kipppunkt/build. Today I'm sharing it. github.com/kipppunkt/bu...

If you're building TUIs with Claude Code or similar AI agents, I made an agent skill for Ink. It organizes the docs so the agent can pull in only what it needs on demand, saving you lots of tokens.

I interviewed someone for a dev position the other day. Remotely. Asked the candidate a very vague question. Got an extremely thorough answer. Really impressive. Left a weird aftertaste, though. I just typed the question into ChatGPT. Same answer 💀

It's kinda crazy how React went from "it's just a super lightweight rendering library, bro" to "whoopsie, our server-side execution layer's complex custom data-format serializer had a prototype-pollution bug and now it's a CVE-10 RCE."

AI-generated unit tests suck. Claude overshoots. GPT-5 is lazy af. No model has proper common sense. I tinkered around for a long time to get GitHub Copilot to actually work as expected. The result is this workflow.

You'd be mistaken if you thought pigeon droppings on the floor were just a random annoyance. Quite the opposite! They're a real-time heatmap showing you the probability of being hit by pigeon poop at any given spot. And you thought all that statistics knowledge was useless!

One killer use case for AI agents is making sense of minified JavaScript files. I just built a post-install script that monkey-patches a package I depend on. What would have easily taken me half a day was finished in under an hour.

Basic question but I can't figure it out. How are these two design patterns called? In the first, the component structure is fixed, and behavior is controlled *only* through props serving as config. In the second, an extension point via the children prop allows for more flexibility.

Don't be like me. Don't sleep on @playwright.dev's test steps. It took me 4 years to realize how much cleaner, readable, and debuggable my tests could be. Named steps = better readability, clearer reporting, faster debugging. Check out the before/after!

Some tools force you to learn a complicated API and require constant maintenance. Other tools... just work, and that's why it's easy to overlook them. @openfeature.dev is one of those tools. Do I use it daily? Yes. Do I ever have to think about it? No.

I was frustrated with the lack of clear advice on setting up copilot_instructions.md. Most guides are vague, or worse, generic AI slop that *hurts* Copilot's performance. So I experimented and found better ways to make Copilot *actually helpful*. 🧵

A screenshot of a single choice question in the style of the StackOverflow developer survey with the following text:

"What will you do next once AI has replaced you as a programmer, life partner, and parent?

- Cry
- Become a goose farmer
- Pray to the AI overlords
- Take out your rage as a StackOverflow moderator"

Large Language Models (LLMs) with "reasoning" capabilities are super hyped, but new research from Apple shows their "thinking" is often an illusion. Beyond a certain complexity, they fail completely. Key points in the 🧵.

Graph showing LLM accuracy vs. task complexity: Standard (non-reasoning) models perform as good as reasoning models at low complexity (but use fewer tokens). Reasoning models excel at mid-complexity. Both fail catastrophically beyond a threshold, with reasoning models showing abruptly shorter traces.

My learning for that day: the final solution was to use the render props pattern. Kudos to @bhuynh.dev and @taranetz.com for pointing that out. We can even take a step further by leveraging React's `isValidElement` function to support both render props and a standard child component.

import { isValidElement, ReactElement } from 'react';

interface WrapperProps {
children: ReactElement | ((props: { text: string }) => ReactElement)
}

const MyWrapper = ({ children }: WrapperProps): React.ReactElement => {
const isRenderFunction = !isValidElement(children);

return isRenderFunction ? children({ text: 'As render function.' }) : children;
}

export default function App() {
return (
<>
<MyWrapper>
{(props) => <span>{props.text}</span>}
</MyWrapper>
<MyWrapper>
<span>As normal child.</span>
</MyWrapper>
</>
);
}

// renders to: "As render function.As normal child."

React: passing state from a wrapper component to a child. How? I'm building a library that exposes a single wrapper component. Users of this library add the wrapper to their TSX and nest their child component inside it. The wrapper fetches some data that's relevant to the child component.

Code snippet with the following code:

const UserDefinedParentComponent = () => (
<MyWrapper> {/* I need to get state from here ... */}
<UserDefinedChildComponent /> {/* ... to here. */}
</MyWrapper>
);

I tried relying heavily on AI assistants (Claude, ChatGPT, GitHub Copilot) for my latest hobby project, but almost every interaction ended with me thinking, "Screw this, I'll write it myself." For those of you who swear by these tools, what am I missing? How do you actually make them useful?

The release of React 19 might cause you some headaches, if you're a web component creator who happens to name their component events in camelCase (instead of kebab-case as per convention). Let me explain:

Code snippet with the following JSX code:

```
// ✅ this will work
<my-camera-web-component onimage-capture={handleImageCapture} />

// ❌ this won't
<my-camera-web-component onimageCapture={handleImageCapture} />
```

My fellow web developers, where do you stand on this? When passing props from a parent to a child component/function, do you prefer: 1. Passing the object (reference) 2. Passing only the specific values needed?
