Yes, ripgrep (or specifically, the Rust regex crate) takes inspiration from Hyperscan for its SIMD matching. https://github.com/rust-lang/regex/commit/203c509df9e1dcba61... Both libraries also rely on a numbe

Do you have a source for this, or are you just reading the statement I quoted differently than I am? The way I read the quote, you use TF-Lite to produce a quantized TF-Lite model, and then use a cloud based compiler to compile it for the a

Am I missing something, or are they not only not documenting the chip, they are also not even releasing the compiler, but requiring you to use a cloud based compiler: > You need to create a quantized TensorFlow Lite model and then compil

Yeah, SDR is one of the reasons I wanted to learn more about DSP. SDR, digital audio processing, digital image processing (especially compression and filtering), all of them have roots in DSP. That looks like an interesting resource, but I

This book uses BASIC, which I just find quite unreadable. I don't know of what other resources are available, but I do know I've seen some that use Matlab. I've never played with Octave much, so I don't know how compatib

I've been wanting to learn more about DSP, and this looks like a good free resource, but the examples in BASIC are just so hard to read, between the line numbers and SHOUTY CASE. While I suppose it would be a good exercise to translate

I think that that's the point of it being metrically identical. You can work in Courier Prime any time you want, and then switch to Courier for submitting your screenplay without worrying about it changing the pagination. So it can hel

Yeah, there are a lot more options for easy, small-batch prototyping PCBs these days. OSH Park was one of the first that was really easy and accessible to hobbyists, so even if it's not the best or the cheapest any more, the purple sol

I love that OSH Park ( https://oshpark.com/ ) uses purple soldermask. It's a fairly unusual soldermask color, but they use only purple. It looks great with gold plating, and it gives a satisfying sense of branding to for

Thanks for the references! I'm familiar with the concept of hysteresis, but hadn't been familiar with the idea of power sequencing for MOS devices, such as the VDD + 0.6V maximum ratings or latch-up. That's good to know!

I'd say that most of these are language features. The only that are mostly library features are operator overloading and simd, but they both have associated language features supporting them. I agree that completeness is hard, but I fe
