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

news.ycombinator.com Unknown 2025-12-30 21:40:13

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

Trump promised a drilling boom, but US energy industry hasn’t been interested

arstechnica.com Unknown 2025-12-30 22:26:37

“We will drill, baby, drill,” President Donald Trump declared at his inauguration on January 20. Echoing the slogan that exemplified his energy policies during the campaign, he made his message clear: more oil and gas, lower prices, greater exports. Six months into Trump’s second term, his administration has little to show on that score. Output is ticking up, but slower than it did under the Biden administration. Pump prices for gasoline have bobbed around where they were in inauguration week.
