Thanks for the added context on the builds! As "foreign" BW player and fellow speech processing researcher, I agree shallow contextual biasing should help. While not difficult to implement, most generally available ASR solutions don't make it easy to use. There's a PR in ctranslate2 implementing the same feature so that it could be exposed in faster-whisper: https://github.com/OpenNMT/CTranslate2/pull/1789

Project mention: Exploring biphasic programming: a new approach in language design | news.ycombinator.com | 2024-07-02
I'm going to hijack the mention of ML to share xbyaku, a c++ library presenting a DSL for assembling machine code at runtime (useful for JIT).
It's used by some of the pytorch back ends.
https://github.com/herumi/xbyak
Example use: https://github.com/oneapi-src/oneDNN/blob/main/src/cpu/aarch...
I learned about these through a blog post about speeding up pytorch on ARM: https://pytorch.org/blog/optimized-pytorch-w-graviton/

Kratos
Kratos Multiphysics (A.K.A Kratos) is a framework for building parallel multi-disciplinary simulation software. Modularity, extensibility and HPC are the main objectives. Kratos has BSD license and is written in C++ with extensive Python interface. (by KratosMultiphysics)

For my tasks, I had some success with algebraic multigrid solvers as preconditioner, for example from AMGCL or PyAMG. They are also reasonably easy to get started with.

https://github.com/ddemidov/amgcl
But I only have to deal with positive definite systems, so YMMV.
I am not sure whether those libraries can deal with multiple right-hand sides, but most complexity is in the preconditioners anyway.

Project mention: We asked camera companies why their RAW formats are all different and confusing | news.ycombinator.com | 2025-04-04
Fujifilm lossy compressed raw still isn't supported after many years [1].
[1] https://github.com/darktable-org/rawspeed/issues/366
And in my experience there has been lots of bugs with Fujifilm raws in darktable:
[2] https://github.com/darktable-org/rawspeed/issues/354
[3] https://github.com/darktable-org/darktable/issues/18073
However, Fujifilm lossless compressed raw actually does a decent job keeping the file sizes down (about 50% to 60% the file size of uncompressed) while maintaining decent write speed during burst shooting.
