  • Interesting. I remember there was a brightness concern with the satellites reflecting too much light, but assumed it was all ok because IIRC they hit their reflectivity reduction targets.

    However, this seems to be about transmissions from the satellites interfering with non-visible observations.

    In a study, published in the Astronomy & Astrophysics journal, scientists used a powerful telescope in the Netherlands to observe 68 of SpaceX’s satellites and detected emissions from satellites are drifting out of their allocated band, up in space.

    … “Why this matters is because of the number,” Dr Di Vruno said. “Suppose that there is a satellite in space that radiates this kind of signal, there is a very, very small chance that this satellite will be in the beam, in the main site, of your telescope.”




  • I still use free GPT-3 as a sort of high level search engine, but lately I’m far more interested in local models. I havent used them for much beyond SillyTavern chatbots yet, but some aren’t terribly far off from GPT-3 from what I’ve seen (EDIT: though the models are much smaller at 13bn to 33bn parameters, vs GPT-3s 145bn parameters). Responses are faster on my hardware than on OpenAI’s website and its far less restrictive, no “as a large language model…” warnings. Definitely more interesting than sanitized corporate models.

    The hardware requirements are pretty high, 24GB VRAM to run 13bn parameter 8k context models, but unless you plan on using it for hundreds of hours you can rent a RunPod or something for cheaper than a used 3090.
