New Nuclear Rocket Concept Could Slash Mars Travel Time in Half

gizmodo.com Passant Rabie 2025-09-25 10:00:58

Engineers from Ohio State University are developing a new way to power rocket engines, using liquid uranium for a faster, more efficient form of nuclear propulsion that could deliver round trips to Mars within a single year. NASA and its private partners have their eyes set on the Moon and Mars, aiming to establish a regular human presence on distant celestial bodies. The future of space travel depends on building rocket engines that can propel vehicles farther into space and do it faster. Nucl

Building Modular Rails Applications: A Deep Dive into Rails Engines

news.ycombinator.com Unknown 2026-01-17 00:30:31

I’ve been building Rails applications for the last 10 years on a daily base and almost all of them use active storage now.

theverge.com Jess Weatherbed 2026-01-18 02:35:57

It’s been 16 months since a DMA ruling allowed iOS developers like Google and Mozilla to use their own browser engines in the EU, so… where are they? According to the Open Web Advocacy (OWA) — a nonprofit group of software engineers that advocates for the open web — Apple continues to place technical and financial restrictions on WebKit-alternative iOS browser engines that effectively stifle competition. OWA says these barriers include insufficient testing tools outside of the US, hostile legal
