  • Ugh… This is all based on Dan Gryder’s YouTube channel. He’s not exactly the most trustworthy person. His channel is full of criticisms of pilots that have died flying that basically amount to “the pilot was dumb” and then when he causes a nearly mutli-fatal accident in a Lockheed 12A because he forgot to lock the tail wheel before landing, he feuds with the YouTuber that pointed this out.

    He constantly derides the FAA and government in general, stating they are incompetent. He has stolen aircraft accident investigation evidence from a crash scene, a violation of federal statute. There’s the defamation lawsuit he lost against a pilot in 2023 to the tune of $1 million. And he was arrested in 2009 at an airport in Georgia.

    Dan Gryder is an attention seeker who will say anything to receive publicity.

    Edit: here’s the analysis on his Lockheed 12A crash: https://youtu.be/sQhA-R2kKbo





  • SLS is on track to be more expensive when adjusted for inflation per moon mission than the Apollo program. It is wildly too expensive, and should be cancelled.

    This coupled with the fact that the rocket is incapable of sending a manned capsule to low earth orbit which is the the lunar gateway is planned to a Rectilinear Halo Orbit instead.

    Those working in the space industry know that SpaceX’s success is not because of Elon but instead Gwynne Shotwell. She is the President and CEO of SpaceX and responsible for all things SpaceX. The best outcome after the election is to remove Elon from the board and revoke his ownership of what is effectively a defense company for political interference in this election. Employees at SpaceX would be happy, the government would be happy, and the American people would be happy.


  • The technical definition of AI in academic settings is any system that can perform a task with relatively decent performance and do so on its own.

    The field of AI is absolutely massive and includes super basic algorithms like Dijsktra’s Algorithm for finding the shortest path in a graph or network, even though a 100% optimal solution is NP-Complete, and does not yet have a solution that is solveable in polynomial time. Instead, AI algorithms use programmed heuristics to approximate optimal solutions, but it’s entirely possible that the path generated is in fact not optimal, which is why your GPS doesn’t always give you the guaranteed shortest path.

    To help distinguish fields of research, we use extra qualifiers to narrow focus such as “classical AI” and “symbolic AI”. Even “Machine Learning” is too ambiguous, as it was originally a statistical process to finds trends in data or “statistical AI”. Ever used excel to find a line of best fit for a graph? That’s “machine learning”.

    Albeit, “statistical AI” does accurately encompass all the AI systems people commonly think about like “neural AI” and “generative AI”. But without getting into more specific qualifiers, “Deep Learning” and “Transformers” are probably the best way to narrow down what most people think of when they here AI today.
