Another option is to build your own. You could buy a small ARM board like a NanoPi R6S (<$100) with 2.5GbE ports and run pfSense on it.

Are you using Windows’ built-in Powershell? If so, are you allowed to install the newer Powershell Core (based on .NET Core)? The latter has a lot of fixes and improvements compared to the built-in Powershell.

zlib-ng also has adler32 implementations optimized for various architectures: https://github.com/zlib-ng/zlib-ng

Might be interesting to benchmark their implementation too to see how it compares.

The complicated number encoding scheme you mentioned is a hexfloat: C has them too.

Hexfloat can be really useful when you need precise/exact floating-point constants for numerical methods. Without them, you end up having to do more-complicated hacks to preserve exact constant values when code gets compiled, or you have to live with compilers (sometimes) subtly altering constants.

I wish more languages supported hexfloats.

I think it’s more like Gandiva or DataFusion (both from the Apache Arrow project).

M-DISC: https://en.m.wikipedia.org/wiki/M-DISC

They’re special DVD and Blu-ray discs designed for long-term storage. DVD and Blu-ray are so widely used, it seems likely you’d be able to find some equipment in 30 years that could still read them.
