Pnpm has a new setting to stave off supply chain attacks

news.ycombinator.com Zoltan Kochan 2025-09-21 10:12:56

There have been several incidents recently where popular packages were successfully attacked. To reduce the risk of installing a compromised version, we are introducing a new setting that delays the installation of newly released dependencies. In most cases, such attacks are discovered quickly and the malicious versions are removed from the registry within an hour. The new setting is called minimumReleaseAge . It specifies the number of minutes that must pass after a version is published before

React is winning by default and slowing innovation

news.ycombinator.com Your Name 2025-09-26 18:46:01

React-by-default has hidden costs. Here's a case for making deliberate choices to select the right framework for the job. React Won by Default – And It’s Killing Frontend Innovation React is no longer winning by technical merit. Today it is winning by default. That default is now slowing innovation across the frontend ecosystem. When teams need a new frontend, the conversation rarely starts with “What are the constraints and which tool best fits them?” It often starts with “Let’s use React; e

5,500 Superconducting Wires Survive Intense Testing for World’s Largest Fusion Reactor

gizmodo.com Gayoung Lee 2025-09-27 01:30:05

Stakeholders around the world are vying to realize nuclear fusion—a fossil fuel alternative that promises maximum energy generation with minimal environmental risk. Behind the efforts to build the world’s largest fusion reactor is an equally gigantic global collaboration: ITER, which has just announced a major advance in its quest to prove fusion’s viability. In a paper published September 11 in Superconductor Science and Technology, the ITER Collaboration reported completing a key test to vali

The US is trying to kick-start a “nuclear energy renaissance”

arstechnica.com Unknown 2025-09-28 01:23:03

In May, President Donald Trump signed four executive orders to facilitate the construction of nuclear reactors and the development of nuclear energy technology; the orders aim to cut red tape, ease approval processes, and reshape the role of the main regulatory agency, the Nuclear Regulatory Commission, or NRC. These moves, the administration said, were part of an effort to achieve American independence from foreign power providers by way of a “nuclear energy renaissance.” Self-reliance isn’t t

New pathway engineered into plants lets them suck up more CO₂

arstechnica.com Unknown 2025-09-29 17:09:00

Lots of people are excited about the idea of using plants to help us draw down some of the excess carbon dioxide we've been pumping into the atmosphere. It would be nice to think that we could reforest our way out of the mess we're creating, but recent studies have indicated there's simply not enough productive land for this to work out. One alternative might be to get plants to take up carbon dioxide more efficiently. Unfortunately, the enzyme that incorporates carbon dioxide into photosynthes

Performance-focused forks of styled-components

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.

Reshaped is now open source

news.ycombinator.com Unknown 2025-10-02 20:32:49

About five years ago, I started Reshaped. I built it for myself, since I had a few projects in urgent need of a component library for both React and Figma. Having worked in the design systems space for over a decade, I had developed a clear sense of what a good design system should be — and what tends to go wrong in others. I noticed that no matter how trends evolve, around 80% of the web is still built on the same core design practices. So I set out to build a system that covers that 80%, whil

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

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.

China Takes a Key Step Toward Its ‘Meltdown-Proof’ Nuclear Reactor

gizmodo.com Gayoung Lee 2025-10-24 13:35:51

China’s ambitious plan to dramatically pull back from fossil fuels is perhaps most evident in the explosive growth of its nuclear energy program. The latest news suggests China may be tantalizingly close to bringing self-cooling reactors to practical use—a development with profound safety implications. In a statement earlier this week, the China Institute of Atomic Energy (CIAE) announced that it had recently concluded tests for a residual heat removal system for integral fast reactors (IFRs).

Practical approach for streaming UI from LLMs

news.ycombinator.com Tim Etler 2025-10-27 23:51:40

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.

“Every frame has something unnerving in it,” Patton Oswalt says in the trailer for Chain Reactions—a new documentary about the enduring influence and impact of 1974’s The Texas Chain Saw Massacre. Tobe Hooper’s grisly classic has often been imitated and has spawned some regrettable sequels and remakes, but the original remains a uniquely terrifying product of a very specific time and place, not just in pop culture, but also in the realms of independent cinema.

Picking a Spot for NASA’s Lunar Nuclear Reactor Is Trickier Than It Sounds

In a bold, strategic move for the U.S., acting NASA Administrator Sean Duffy announced plans on Aug. 5, 2025, to build a nuclear fission reactor for deployment on the lunar surface in 2030. Doing so would allow the United States to gain a foothold on the Moon by the time China plans to land the first taikonaut, what China calls its astronauts, there by 2030.

Physicists Catch ‘Ghost Particles’ Bouncing Off Matter in Record-Breaking Experiment

Neutrinos are everywhere. About 100 trillion neutrinos pass through our bodies every second, but they’re so weakly interacting we never notice them. It’s this spooky feature of neutrinos that earned them the nickname “ghost particles.” Antineutrinos, their antimatter counterpart, are also everywhere. Both are notoriously difficult to detect, but physicists are getting better at circumventing their ghostly tendencies, as a recent record-setting measurement demonstrates. When a low-energy neutrin
