Ask HN: How will the OSA affect small Mastodon instances?

news.ycombinator.com Unknown 2026-01-04 15:40:13

I am not currently a user of Mastodon, but I have some interest in the project. I was looking at some stuff that seemed to indicate to me that the OSA could make it difficult to self host Mastodon without providing age verification. I was then reading the provisions and realsised that it didn't really affect you unless you have at least 3 million monthly users, so in theory would not affect self hosters with only a few users. But then I thought that if you are federated with a very large instanc

Meta's AI spending spree is Wall Street's focus in second-quarter earnings

cnbc.com Jonathan Vanian 2026-01-04 21:00:01

Mark Zuckerberg, CEO of Meta Platforms Inc., arrives for the Meta Connect event in Menlo Park, California, on Sept. 25, 2024. Meanwhile, revenue growth in the second quarter likely slowed to 15%, down from 22% a year earlier, according to LSEG. It would be the slowest rate of expansion for the company since early 2023, and analysts are expecting lower levels of growth in the coming quarters.

This founder left Silicon Valley to challenge U.S. defense supremacy from Athens, and investors are paying attention

techcrunch.com Connie Loizos 2026-01-04 21:05:34

In the summer of 2021, Dimitrious Kottas made a move that would be unfathomable to most Silicon Valley engineers: after leaving his coveted position at Apple’s Special Projects Group, he packed up his life in California and moved back to Athens to start a defense company. Three and a half years later, his startup, Delian Alliance Industries, has set up solar-powered surveillance towers that monitor some of Greece’s borders around the clock and detect wildfires on remote islands, along with a pi

This startup wants to use the Earth as a massive battery

technologyreview.com Casey Crownhart 2026-01-05 05:00:00

In traditional pumped hydro storage facilities, electric pumps move water uphill, into a natural or manmade body of water. Then, when electricity is needed, that water is released and flows downhill past a turbine, generating electricity. Quidnet’s approach instead pumps water down into impermeable rock formations and keeps it under pressure so it flows up when released. “It’s like pumped hydro, upside down,” says CEO Joe Zhou.

C. Scott Brown / Android Authority TL;DR The Galaxy S26 series could not only ditch the Plus model, but could also kill the standard model. Evidence found in an internal One UI 8 build suggests a lineup of the Galaxy S26 Pro, Galaxy S26 Edge, and Galaxy S26 Ultra. That means Samsung may rename the base model to “Pro” and replace the “Plus” model with Edge.

herraez/Getty Images The changes in the latest Linux kernel, Linux 6.16, may be small, but they include some significant ones. Linus Torvalds himself summed up this release as looking fine, small, and calm, but not "really not all that interesting (in all the best ways!)." Here's my list of what's new and improved. First, the Rust language is continuing to become more well-integrated into the kernel. At the top of my list is that the kernel now boasts Rust bindings for the driver core and PCI

The causes of revolutions and major rebellions are in many ways similar to processes that cause earthquakes (Goldstone 1991: 35). In both revolutions and earthquakes it is useful to distinguish the structural conditions (pressures, which build up slowly) from triggers (sudden releasing events, which immediately precede a social or geological eruption). Specific triggers of political upheavals, such as self-immolation of a fruit vendor, which triggered the Arabic Spring in Tunisia, are very hard
