A Celestial Rendezvous: The Moon Meets Mars in a Rare Occultation
  • Hallucinations in the article? “This phenomenon occurs because the Moon's apparent size in the sky, due to its proximity to Earth, is roughly the same size as some celestial objects like Mars.” The moon is definitely not the same size as mars in the sky.

  • What is the Anti Commercial-Al license and why do people keep adding it to their comments?
  • Yes but the default state is that you have copyright over your posts/comments, and by sending them to your Lemmy server you are giving them some license to at least distribute the content to others (most services specify what license you are giving them in the ToS, which is where they would say that you are licensing them to sell you shit to AI companies). In theory by specifying the CC-SA-NC license or whatever that should be the license unless your Lemmy instance has some ToS terms that specifically say you’re granting additional privileges to someone by posting.

    Whether AI companies actually care (they don’t) is a different story, but if eventually they actually have to follow copyright laws like everyone else then it could matter.

  • If presidential immunity is absolute..
  • NSA is civilian, they work closely with CSS which is the military side. The determining factor for civilian vs military is whether the people working there are enlisted soldiers/commissioned officers or civilians who just get hired like other jobs.

  • Debris from burning satellites could be affecting Earth's magnetic field | Space
  • I looked at the paper they’re talking about (which has not yet been peer reviewed), and I couldn’t find any past peer reviewed research from the author. The paper also doesn’t really explain any of its arguments past referencing sometimes unrelated stuff that “sounds scientific,” so I suspect it will be rejected from any reasonable journal. Some of their graphs seem to have problems and their comparisons to the mass of the Van Allen belts seem questionable. Also radiation belts don’t really “protect earth”.

    Writing a news article based on a Arxiv article from an author that isn’t established seems extremely dubious.

  • Dead satellites are filling space with trash. That could affect Earth’s magnetic field | Sierra Solter
  • I looked at the paper they’re talking about (which has not yet been peer reviewed), and I couldn’t find any past peer reviewed research from the author. The paper also doesn’t really explain any of its arguments past referencing sometimes unrelated stuff that “sounds scientific,” so I suspect it will be rejected from any reasonable journal. One example is the statement that the Van Allen belts protect earth, they are just belts of captured particles that could have been harmful to earth. There have been proposals to eliminate them to protect satellites (see https://apps.dtic.mil/sti/tr/pdf/AD1095699.pdf). Also I don’t like how they keep using their quoted van allen belt mass of 180 mg to make other numbers seem very large, what makes the Van Allen belts relevant is their electrons have a lot of energy (moving at >0.2 c), whereas the particulate from reentry is much lower energy. The paper doesn’t explain how lots of low energy particulate is related to a tiny amount of captured high energy radiation, so mass comparisons between them (“a billion times heavier”) don’t make sense.

  • Microsoft unbundles Office and Teams globally in new attempt to appease antitrust regulators
  • When you’re an enterprise client paying serious money for the service, there are often data protection requirements. They have the capability to support things like export controlled information or HIPAA compliance in office, and appropriate legal agreements ensuring data protection. It’s the power of collective bargaining (they are buying 100s++ licenses instead of just one).

  • Game Recommendations

    I’m looking for recommendations on high quality open source games to try. Some of my favorite games I’ve played recently are Factorio, Kerbal Space Program, and Outer Wilds, but I’m willing to try many kinds of games (besides FPS).
