  • I daily drive Fedora and if I had to guess, it’s because you need to manually enable non free software repos and features. If you don’t know what to look for, you can easily get frustrated by things like poor hardware acceleration in browsers (due to some codecs being nonfree and hence not available OOTB) and worse driver availability. IIRC you need to manually add the repos, you can’t just toggle something in settings.

    Other distros tend to bundle these things (or give you a direct toggle).






  • I work in an area adjacent to autonomous vehicles, and the primary reason has to do with data availability and stability of terrain. In the woods you’re naturally going to have worse coverage of typical behaviors just because the set of observations is much wider (“anomalies” are more common). The terrain being less maintained also makes planning and perception much more critical. So in some sense, cities are ideal.

    Some companies are specifically targeting offs road AVs, but as you can guess the primary use cases are going to be military.






  • The general framework for evolutionary methods/genetic algorithms is indeed old but it’s extremely broad. What matters is how you actually mutate the algorithm being run given feedback. In this case, they’re using the same framework as genetic algorithms (iteratively building up solutions by repeatedly modifying an existing attempt after receiving feedback) but they use an LLM for two things:

    1. Overall better sampling (the LLM has better heuristics for figuring out what to fix compared to handwritten techniques), meaning higher efficiency at finding a working solution.

    2. “Open set” mutations: you don’t need to pre-define what changes can be made to the solution. The LLM can generate arbitrary mutations instead. In particular, AlphaEvolve can modify entire codebases as mutations, whereas prior work only modified single functions.

    The “Related Work” (section 5) section of their whitepaper is probably what you’re looking for, see here.
