    Hi, fair enough. I've thoroughly immersed myself in this stuff enough that I sometimes don't realise people aren't as familiar with the concepts and jargon. I'm going to write anot…

    Are you saying my statement is very abstract? or down to earth?

    ok? well, textbooks can be wrong or misguided.

    Nah, special relativity is a consequence of magnetism.

    Interesting, I need to look into Maxwell's original formulation with the vortices. You can write electrodynamics in terms of small spinning elements: https://forwardscattering.org/…

    Kolomogorov complexity as an objective measure of the information contained in a string just doesn't work. It depends entirely on the language used for the program, and for any str…

    Wonderful stuff, good job Midjourney. An AI can be trained on body scans to detect diseases, tumours etc. Ideally this can be trained on real scans with real diseases but you could…

    So now the algorithm is patent-free, and the vertex and fragment shaders are open-sourced with the MIT license, what we presumably need is some open-source code to take Bezier curv…

    Awesome, thanks.

    I was going to ask if Slug can be used as a general vector renderer. Or does it assume limits on e.g. number of curves/paths per area that are typical of fonts?

    Here's my fast acos, which I think can be converted to an asin: https://forwardscattering.org/post/66

    For simple models (constant incoming radiance), you can indeed just add the optical depths from the different fog 'layers'. (90% sure but the maths is easy to check anyway, see htt…

    Coincidentally I just posted a blog post on fog rendering, in particular with exponential height fog, yesterday: https://forwardscattering.org/post/72

    Use a multithreaded blocking approach. Much nicer than async.

    I haven't thought about it deeply. But I guess it's about allowing the model to easily distinguish the prompt from the conversation. Models seem to get confused with escaping, whic…

    They could be if models were trained properly, with more carefully delineated prompts.

    I use webassembly for Substrata ( https://substrata.info/ ). It works pretty well, allows building a c++ app using OpenGL for the web.

    When you have done enough C++ you don't need to fire up compiler explorer, you just use local variables to avoid aliasing pessimisations. I also wrote about this a while ago: https…
