    As an academic who is forced to review AI-generated conference/journal submissions, I can assure you this is not the case. LLM-heavy papers are terrible. Even if they manage to avo…

    The mathematical field of Differential Geometry can answer this question precisely: https://en.wikipedia.org/wiki/Geodesic#Affine_geodesics An oblate spheroid is an example of a Ri…

    In this example, random numbers provoked the worst case too often. However, in other situations random numbers are "too nice". For example, a random matrix with independent identic…

    For math and writing, we still have in-class exams as an LLM-free evaluation tool. I wish there was some way to do the same for programming. Imagine a classroom full of machines wi…

    This paper may be interesting to you. It touches on several of the topics you mentioned: https://www.science.org/doi/10.1126/scirobotics.abm6597

    10 years ago it was already folklore that compilers ignore the "inline" keyword when optimizing, but that was false for clang/llvm: https://stackoverflow.com/questions/27042935/are…

    It is not even close. Almost every branch of modern mathematics includes an important contribution from Euler in its history. Erdos was a specialist by comparison. If you sample a …

    I applied to tenure-track positions the current cycle. A lot of places were hiring non-TT lecturers too, and a few were hiring only non-TT. The application-submitting phase of the …

    Here is a recent and interesting paper connecting GJK and convex optimization [1]. They show that GJK is equivalent to the iterations of the Frank-Wolfe algorithm applied to the QP…

    For simple applications there's no need to learn about quaternions at all. There could be a library type called Rotation3D or something. You should never need to know which represe…

    If the author is here: I would really enjoy leaderboards!

    Midshipman hitch is great, I used it to reinforce my tomato cages with some tension members.

    Good luck. Still calm here in northeast LA too.

    My siblings and I replaced my parents' rickety exterior stairs. It was super gratifying to make their house safer and save them thousands of dollars while having fun.

    But why isn't the proposed method an instance of smart guessing? It reduces oracle complexity with heuristics. The heuristic is "build a machine learning model of the objective fun…

    How can your prior be uniform if the hypothesis class is unbounded?

    (assuming math-ish problems) Try to solve a simpler version of the problem. Keep making simplifying assumptions until you get something you can handle. Often you realize that some …

    Of course, but ROS makes it easier to slip into this flawed process. I prefer tools that help you avoid bad engineering processes.

    I worked on a robotics project with a large team using ROS1. The loose coupling is pernicious: It's easy for everyone to work on their own ROS node in isolation and avoid testing t…

    I think the real strength of this method is that it doesn't require the data live in a vector space. Once you give up that structure, you're pretty much locked in to using points f…
