I think you are mostly correct. However if we expand beyond SMPTE to ISO, the modern C++ standards process provides a counterexample.

Great, now do AES and IEEE.

There is no benchmark in the post. There is analysis, discussion and code examples for epoll and io_uring usage.

If you sort your fields by size or manually pad them with natural alignment, and use #pragma pack or equivalent non-standard directives that gets you most of the way there. But yes, avoid bitfields. C++ "standard layout type" is t

CIC filters also use a simple efficient recursive algorithm: just an accumulator and a delay line. No built-in frequency selectivity. https://www.dsprelated.com/showarticle/1337.php Agree re transients. I think Miller

Nice. To the folks saying "nothing to see here" this appears to be a variation of filter-bank spectral analysis where each band varies in frequency to track "the" in-band sinusoid. Somewhat like a bank of PLLs each with

I think you have it sideways. STUN [1] is the NAT traversal / "NAT hole punching" process that allows peers to discover their public IP addresses and establish direct P2P bidirectional UDP communication. WebRTC depends on STU

In this case we're talking about P2P traffic, which is generally not HTTPS. The linked issue references WebRTC https://en.wikipedia.org/wiki/WebRTC

You think IDF-grade packet inspection causes lag?

by RossBencina 4mo ago
Wild hypothesising here on HN but if you read to the end of the GH issue users have been reporting that STUN has been failing (i.e. no P2P link establishment, fallback to high-latency relay servers.) Multiple users have been able to work ar

"requires" is of course subjective, there are always multiple ways to do something. But sometimes it is convenient to model a system as concurrent execution streams, for example: multiple sessions (servers), multiple entities (gam

No one seems to have mentioned the obvious question: Does Vivado already run under WINE? If not, are there any major blockers?

I'm sorry to hear about your experiences. I find it hard enough to deal with pushy people who have mismatched expectations (and yes, I'm not proud of it but at times I have been an entitled user.) I don't think what you'

Great read. A question: what is the status of this problem on other architectures such as ARM and RISC-V, would the analysis and solution be the same? e.g. does ARM have invariant TSC?

Excellent post. Two stand-out points are deskilling through abolition of apprenticeship (or equivalent progression through the rank and responsibility), and loss of institutional knowledge, especially tacit knowledge stored in individual pe

If you're interested in audio, PortAudio is an established project with a lot of users. I have no doubt that the docs could be improved. I know this because I wrote a large chunk of the docs and I am frequently impressed by the docs of

I'm not sure what all of the hazards are, but I could imagine a language (or a policy) where public APIs ship with all of the inline fix directives packaged as robust transactions (some kind of "API-version usage diffs"). Whe

Pretty sure in the USA you can patent mathematics if it is an integral part of the realisation of a physical system.* There is a book "Math you Can't Use" that discusses this. * not a legal definition, IANAL.

To be more precise, when working with sampled data with uniform sample rate you use the Discrete Time Fourier Transform (DTFT), not the Fourier Transform!. None the less, you still end up with an approximate spectrum which is the signal spe
