Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

File tagging and encoding
Have you tried using ABP's own metadata tool and then using that to embed the metadata? They use tone. Not sure if it will help you with the m4bs containing mp4 streams - I've never tried dealing with that.

- LG G5 H850 (optional with Bang & Olufsen Hifi-Plus module) + Audiobookshelf + Substreamer
Let me cite my comment from https://news.ycombinator.com/item?id=32042780:
I use m4b-tool[1], tone[2] and audiobookshelf[3] together with an LG G5 H850 smartphone[8] with Bang & Olufsen Hifi-Plus Module for Audio Only and I am pretty happy with this config. For Music I use Navidrome[5] and Substreamer App[7]. Maybe I'll try out Jellyfin[4] or maybe Plex[6], but I really don't wanna go closed source.
I also thought about writing something self hosted in C# to have ONE solution for audiobooks, podcasts and music and started a small private project, but this will take a while until it is ready to release something...
You may ask: Why an LG G5 H850? Well, its relatively small and cheap (about 50 - 80 bucks used) it has an audio Jack, USB-C, you can change the battery, it can hold up to 2TB microSD storage, has an HiFi Plus module for audio enthusiasts and a descent screen. Besides that it can run lineage os...
Note: I'm the author of the first two projects :-)

> Very neat, I love it, I used to have a tool to do this but it's been ages and is now unmaintained.
Thank you :-) Glad to hear that.
> Just be sure to do input santization, since if someone else uses your code it could go from a very cool project to a backdoor that ends up on the front page for all the wrong reasons :-)
Good point. I think that the "scriptable" part needs special care regarding security issues, as well as the metadata-readers and JSON parsers. I don't want that to bite me in the neck because of a "malicious" file. Maybe it is worth to provide a responsible disclosure email and make a plan for security issues.

Mysterious Moving Pointers
Yeah I pretty much only use my own alternate container implementations (from KJ[0]), which avoid these footguns, but the result is everyone complains our project is written in Kenton-Language rather than C++ and there's no Stack Overflow for it and we can't hire engineers who know how to write it... oops.

Show HN: Comprehensive inter-process communication (IPC) toolkit in modern C++
- may massively reduce the latency involved.
Those sharing Cap'n Proto-encoded data may have particular interest. Cap'n Proto (https://capnproto.org) is fantastic at its core task - in-place serialization with zero-copy - and we wanted to make the IPC (inter-process communication) involving capnp-serialized messages be zero-copy, end-to-end.
That said, we paid equal attention to other varieties of payload; it's not limited to capnp-encoded messages. For example there is painless (<-- I hope!) zero-copy transmission of arbitrary combinations of STL-compliant native C++ data structures.
To help determine whether Flow-IPC is relevant to you we wrote an intro blog post. It works through an example, summarizes the available features, and has some performance results. https://www.linode.com/blog/open-source/flow-ipc-introductio...
Of course there's nothing wrong with going straight to the GitHub link and getting into the README and docs.
Currently Flow-IPC is for Linux. (macOS/ARM64 and Windows support could follow soon, depending on demand/contributions.)

Condvars and atomics do not mix
FWIW, my C++ toolkit library, KJ, does the same thing.[0]
But presumably you could still write a condition predicate which looks at things which aren't actually part of the mutex-wrapped structure? Or does is the Rust type system able to enforce that the callback can only consider the mutex-wrapped value and values that are constant over the lifetime of the wait? (You need the latter e.g. if you are waiting for the mutex-wrapped value to compare equal to some local variable...)

I don’t understand zero copy
The second one is to encode data in such a way that you can read it and operate on it directly from the buffer. You write data in a layout that is the same, or easily transformed as types in memory. To do that you usually need to encode with a known schema, only Sized types to efficiently compute fields locations as offsets in the buffer, and you usually represent pointers as offset into the encode. You can look at capnproto protocol for instance https://capnproto.org/

A Critique of the Cap'n Proto Schema Language
With all due respect, you read completely wrong.
* The very first use case for which Cap'n Proto was designed was to be the protocol that Sandstorm.io used to talk between sandbox and supervisor -- an explicitly adversarial security scenario.
* The documentation explicitly calls out how implementations should manage resource exhaustion problems like deep recursion depth (stack overflow risk).
* The implementation has been fuzz-tested multiple ways, including as part of Google's oss-fuzz.
* When there are security bugs, I issue advisories like this:
https://github.com/capnproto/capnproto/tree/v2/security-advi...
* The primary aim of the entire project is to be a Capability-Based Security RPC protocol.

Sandstorm: Open-source platform for self-hosting web app
I like how they use capability-based security [0] and use Cap'n Proto protocol. This is another technology that is slow to get broad adoption, but has many things going for when compared to e.g. Protocol Buffers (Cap'n Proto is created by the primary author of Protobuf v2, Kenton Varda).
