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.

Your idea for the secret to prevent spoofing is interesting and reminiscent of the verification secret in the SCTP packet header: https://en.m.wikipedia.org/wiki/SCTP_packet_structure

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.

Now could be a good time to make this change, in coordination with HPy: https://github.com/hpyproject/hpy

I agree though — it’s tempting to keep extending and stretching the language to be something it was never designed for; but at some point it’s been stretched so far it loses the properties that made it attractive to start with. I like Python, but some of the things people are using it for now, they should really consider another language instead, and write a Python wrapper on top of that if they must use it from Python.

The Opal webcam ($300) looks fairly similar in specification to the new(ish) Dell UltraSharp webcam ($200): https://www.dell.com/en-us/shop/dell-ultrasharp-webcam/apd/3...

What is Opal offering over the Dell webcam for the extra $100?

profquail — Tue, 22 Jun 2021 02:28:16 +0000

Kats looks like a useful library, but I’m a bit surprised to see they’re not enabling parallel execution for the numba kernels. Surely FB must have time-series data large-enough they’d see some performance benefits from parallelism in these functions?
