Why HN links it
HN commenters link this blog's ROC tutorial on low-latency peer-to-peer audio streaming and a post on broken file locking. The comments point to these as resources rather than judging the writing.
Summarised by Claude from a sample of 5 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
This reminds me a bit of ROC [0], though definitely seems more polished. One thing nice about ROC is its pulseaudio plugin for native integration as a sink. [0]: https://gavv.github.io/articles/roc-tutorial/

HN discussionI keep seeing this argument in this thread and quite frankly I'm dumbfounded. Last time I've had this issue was more than a decade ago on FreeBSD and it was solved by tweaking my OSS config to enable multiple channels. I've never, ever had this issue with Alsa. And I'm not a fan of Alsa either, PA just managed to be even more opaque and less reliable in my experience. Now, it's just anecdotic evidence of course but…

HN discussionI can't talk about that, but I will make a recommendation to try streaming with ROC. I've done quite a bit of streaming in the past with pulseaudio-dlna and the extreme lag isn't fantastic. https://gavv.github.io/articles/roc-tutorial/ I'm also curious about using PW, I upgraded, but I haven't setup any streaming yet.

HN discussionTry https://danluu.com/file-consistency/ for one point: the filesystem isn't really even viable for data persistence. The filesystem's "you can only persist uninterpreted bytes" policy means software can't maintain any kind of data invariant across runs; everything has to be revalidated if your process ends. ACLs (e.g. unix permissions) are widely regarded as a mistake. File locking is broken: https://gavv.github.io…

HN discussionSo far I mostly tested Roc on several 2.4 Ghz Wi-Fi networks. You can usually expect 100-500 ms in this case (depending on the network). See "Typical configuration" in this article[1]. Most likely you will be able to achieve lower latencies on a better channel, but I did no serious testing for lower latencies yet. This is in my to-do list.
