8BitDo’s wireless N64-inspired controller is 30 percent off

theverge.com Cameron Faulkner 2025-09-21 04:09:25

I’ve been seeing emails in my inbox every week about how RTX 50-series GPUs are in stock at many retailers, but the bigger news is that stock is apparently so plentiful that we’re seeing deals worth sharing. Whether you have a small form factor desktop build or not, thewith a triple-fan setup takes up just 2.5 slots in your case, making it a compact option if you’re trying to keep your components neatly tucked. This model debuted at $829.99, but for the past couple of weeks it has been available

Performance-focused forks of styled-components

news.ycombinator.com Unknown 2025-09-28 18:00:52

Your React app might be 40% slower on first render than it needs to be. Not because you wrote bad code. Not because React is slow. But because styled-components never implemented React 18's useInsertionEffect hook: a feature specifically designed to solve CSS-in-JS performance problems. While React 18 shipped in March 2022 with this optimization path, styled-components remained on React 17 patterns, injecting styles during render instead of between render and layout. This creates a performanc

Type checking is a symptom, not a solution

news.ycombinator.com Paul Tarvydas 2025-10-08 03:56:19

What if the programming industry’s decades-long obsession with type checking is solving the wrong problem entirely? What if our increasingly sophisticated type systems—from Haskell’s category theory to Rust’s borrow checker—are elaborate workarounds for fundamental architectural mistakes we’ve been making since the beginning? The software industry has convinced itself that type checking is not just useful, but essential. We’ve built entire programming languages around the premise that catching

Ripple is a TypeScript UI framework for web (If React and Svelte had a baby)

news.ycombinator.com Unknown 2025-10-13 12:26:48

What is Ripple? Currently, this project is still in early development, and should not be used in production. Ripple is a TypeScript UI framework that takes the best parts of React, Solid and Svelte and combined them into one package. I wrote Ripple as a love letter for frontend web – and this is largely a project that I built in less than a week, so it's very raw. Personally, I (@trueadm) have been involved in some truly amazing frontend frameworks along their journeys – from Inferno, where

Practical approach for streaming UI from LLMs

news.ycombinator.com Tim Etler 2025-10-26 02:51:40

LLMs have enabled us to solve a new class of problems with more flexibility than ever, but as they are language models, they are inherently text powered, which has led to AI-based UI being incredibly text heavy. As someone who has been creating experiences with web technology my entire life, I’m not satisfied with so much UI being replaced with text. At Vetted, we have been building a shopping research assistant, and shopping is an inherently visual and UI heavy space. Products need to display

AOL is finally shutting down dial-up

theverge.com Thomas Ricker 2025-11-25 23:32:48

As a septuagenarian, my father’s story was typical of long-time AOL dial-up subscribers. His subscription was a security blanket. He was sure he didn’t need the dial-up component, but he didn’t want to risk losing access to his stock portfolio, investor forums, and email. His setup worked, and he could afford to keep paying the subscription he had dutifully paid for over a decade. With my help, we were able to migrate everything he used on AOL to the ad-supported and open internet that was alre

Open source BOM management (for me)

Since graduating from university I’ve gotten more and more into embedded software development. This has even spilled over into designing PCBs (printed circuit boards) for my embedded devices to sit on. Initially I had assumed that the leap from software to hardware design would be insurmountable without any formal education but it turned out to be quite enjoyable. It turned out that the problem I’d be facing wasn’t a technical one, but of an organisational nature. Designing circuits Designing

So today, I want to look at useCallback , and to some extent useMemo , in situations where I think they are totally pointless. Why memoize?

XMLUI

news.ycombinator.com View All Posts Jon Udell 2026-01-05 10:03:39

In the mid-1990s you could create useful software without being an ace coder. You had Visual Basic, you had a rich ecosystem of components, you could wire them together to create apps, standing on the shoulders of the coders who built those components. If you’re younger than 45 you may not know what that was like, nor realize web components have never worked the same way. The project we’re announcing today, XMLUI, brings the VB model to the modern web and its React-based component ecosystem. XML

Vibe-Coding a PCB – surprisingly good

About This site provides a large number of ready-to-use cross-compilation toolchains, targetting the Linux operating system on a large number of architectures. Based on gcc and binutils, those toolchains are provided in several variants with the glibc, uClibc-ng and musl C libraries. The toolchains are built using the Buildroot build system. Most toolchains are tested by building a Linux kernel and Linux userspace, and booting it under Qemu. This is of course not possible on some CPU architec
