Wile E. Coyote, despaired, takes a bucket of paint and a brush and paints a beautiful two-bedroom house on a mountainside. He paints a beautiful coyote wife in the window, and two adorable coyote kids running around in the yard. He tries to enter this new coyote life, but it is inaccessible to him

The Good & The Bad When Using LLMs To Write Spack Packages
The Spack package manager is quite popular in the HPC / supercomputer space for scientific software. Even with the more selective niche than a typical general purpose OS package manager, large language models (LLMs) have already proven capable of being useful in generating new Spack packages. But there have also been some headaches involved too for Spack developers...
