Ray
Ray is an AI compute engine. Ray consists of a core distributed runtime and a set of AI Libraries for accelerating ML workloads.
I'm guessing this comment is some kind of "if you know, you know." Likely starting from https://docs.ray.io/en/latest/cluster/vms/user-guides/launch... and then trawling through one of these I guess https://github.com/ray-project/ray/issues?q=is%3Aissue+prem+...

Project mention: Go 1.24's go tool is one of the best additions to the ecosystem in years | news.ycombinator.com | 2025-01-27
https://somesocks.github.io/dryad/
One other alternative I know of that's multi-language is Pants(https://www.pantsbuild.org/), which has support for packages in several languages, and an "ad-hoc" mode which lets you build packages with a custom tool if it isn't officially supported. They've added support for quite a few new tools/languages lately, and seem to be very much an active project.

compiler-benchmark
Benchmarks compilation speeds of different combinations of languages and compilers.
Yea, sounds painful. That’s only 50 lines of code per second.
Swift is the slowest on the compilation benchmarks at https://github.com/nordlow/compiler-benchmark.

tree-hugger
A light-weight, extendable, high level, universal code parser built on top of tree-sitter
> Nienders concluded that this was due to the difference in the information available. Sophy had information about the track curvature of the upcoming 6 seconds of track, based on the current speed. TMRL, however, only had distance measurements from the LIDAR. While the TMRL program could plan for the next turn, it could not plan two turns ahead, and this fundamentally limited the program to mere safe driving, avoiding walls and crashes, but never optimizing.
I think that point is an important one. ML algorithms work better when they are given better context. Especially in programming, it is clear the models are trained on code, rather than repositories. They know about files and repositories, but i always get the impression that they are totally clueless about whole programs.
What could be done better in code, is provide in training more data about where each function is located in the project, some other files where similar functions are defined or called and so on. In general before each code is fed into the training, to do a little bit of data mining in the project like the tree-hugger project [1] enables. Tree-hugger is a little bit older code, and tree-sitter has advanced a lot the last 4 years.
In my opinion 5x to 10x in code, is within reach, with no need to increase GPU compute or electricity.
