Open source isn't a tip jar – it's time to charge for access

A handful thrive, most scrape by as companies make billions off their code

Opinion  Time and again, I see people begging for companies with deep pockets to fund open source projects. I mean, after all, they've made billions from this code. You'd think they could support the code's creators and maintainers. It would be only fair, right?…

Chandra Resolves Why Black Holes Hit the Brakes On Growth

alternative_right shares a report from Phys.org: Astronomers have an answer for a long-running mystery in astrophysics: why is the growth of supermassive black holes so much lower today than in the past? A study using NASA's Chandra X-ray Observatory and other X-ray telescopes found that supermassive black holes are unable to consume material as rapidly as they did in the distant past. The results appeared in the December 2025 issue of The Astrophysical Journal. [...] The team ran tests of the three main possible scenarios currently being considered for the slowdown of black hole growth. These options were: could the decline in black hole growth be caused by less efficient rates of consumption, or by smaller typical black hole masses, or by fewer actively growing black holes? Their analysis of the data, extending over billions of years of cosmic history, led them to the conclusion that black holes are indeed consuming material less rapidly the later they are found after the Big Bang. The researchers expect this trend of slower-growing black holes to continue into the future.
