    That's counterintuitive. I've always wondered how that overlay works and tracks processes, because I've used it to launch MultiMC, then from there launch some Minecraft pack to play using the Steam Controller. Any idea why this doesn't work with the Epic Launcher?

    This is likely a dumb question, but can't you put the Epic Games Store as a game entry in Steam, then launch it from there? I imagine you'd have to have some complicated bindings though.

    I would say check out Gloomhaven and Dragoon - very different games but both are enjoyable.

    This is neat. I wonder if they've considered merging a random amount of adjacent rooms to make some that are not rectangular.

    As an update from last week's thread, I got TensorFlow compiling on NixOS. Unfortunately, it segfaults on simple calls. This is the same behavior as for PyTorch with a ROCm backend for NixOS that I've observed, which means there is probably an issue deeper in the overlay.

    I imagine there is some group theory behind it that makes sense. There appears to be more to the pattern than he points out.

    Well, sort of. ROCm is not an official target for TensorFlow, and neither is NixOS. This is a niche enough problem that I suspect there would be very little interest in providing support. Fortunately the maintainer of the nixos-rocm overlay is both very competent and willing to provide help, so I've mostly been pinging him with questions.

    I've been trying to package TensorFlow with a ROCm backend for NixOS. It's not going well. TensorFlow uses Bazel as a build system, which is horrible for all sorts of reasons, but even more so when combined with NixOS. Lots of paths in the build files are hardcoded and expect to find things at /opt/rocm, which is never true for NixOS. This expectation is probably why the Bazel build files for ROCm don't follow any symlinks, which compounds how difficult it is to package this.

    I'm trying to package Elmer for use with NixOS, and could use some help from any experienced Nix users. My current attempt is located here. There is some junk left around in that file from my experimenting, but it's at least a start. There are also a few lines of error included in the comment here.

    Any help is appreciated!

    I would not know, my knowledge comes from a class I took using Barry Simon's A Comprehensive Course in Analysis. This should be in the first volume, but these are not introductory texts.

    This is a very satisfying answer that I hadn't considered. Edit: To be honest, I'm surprised I didn't realize this myself - I must reread Landau's Foundations of Analysis as a refresher.

    I think the answer is that I hadn't realized that periodicity is equivalent to being in L2 over a real interval. Sine and Cosine are used because they're orthogonal functions in that space, but Fourier Series can be reformulated to use any sequence of orthogonal functions, which means that any function that is periodic can be reformulated to be defined without using trigonometric functions, even trigonometric functions.

    From a mathematical perspective, any function that is in L2 over, say, [0, 1] is periodic. A function in this space that is impossible to compute meaningful values of on a computer is f(x)={0 if x is Rational else 1}. Yet over [0, 1] the area under the function from this perspective is 1 and the Fourier Series would be the same as that for f(x)=1; the ability to compute values of a function like this easily isn't really what I'm looking for.

    I guess one answer to this question I've asked is any fuction in this space, but that sort of loops back to piecewise representation or a Fourier Series to get there.

    Disclaimer: I abused some notation in this post.
