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.

Ask HN: What apps have you created for your own use?
More than I can count, but here are the big ones:
http://moros.cc - A hobby operating system, with a shell, an editor, a lisp interpreter, and many other little things
https://geodate.org - A lunisolar calendar with decimal time (centidays and dimidays)
https://github.com/vinc/geodate - An implementation of the calendar + time
https://github.com/vinc/geocal - A tool to visualize the calendar + time
https://github.com/vinc/littlewing - A chess engine written in Rust (and another one before that in C++)
https://vinc.cc/software/ - A more complete list, on my personal website
I'm good at scratching my own itches but less good at finding projects that could be useful for other people.

Announcing MOROS 0.10.1 - A hobby operating system written in Rust
MOROS is a text-based hobby operating system targeting computers with a x86-64 architecture and a BIOS. It is inspired by Unix and ITS but is closer to a modern DOS at the moment in term of features.
- I made a website for my hobby operating system (MOROS)

MOROS 0.9.0 released
I wrote this a while ago to answer this question: https://github.com/vinc/moros/blob/trunk/doc/index.md
-
MOROS 0.8.0 released
Indeed, it cannot run on most of the latest computers except those that can replace UEFI with coreboot + seabios. See here: https://github.com/vinc/moros/issues/270

[Media] I'm comparing writing a double-linked list in C++ vs with Rust. The Rust implementation looks substantially more complex. Is this a bad example? (URL in the caption)
itโs even written by the same person that wrote the Nomicon (the guide to the dark arts of unsafe)

Rust books to read
If you want to dive deeper you can always have other options but now there are concrete cases, if you want to do low level thing https://doc.rust-lang.org/nomicon/ while if you want multi thread/concurrency stuff https://marabos.nl/atomics/ . There are many many books so you will have to point yourself to what you want

[Media] Hashmap behaviour inside a loop due to lifetime issue
Hope this helps. For more details, see the Rustonomicon. I referenced the subtyping chapter here extensively.

Unsafe Rust
Nice video! Glad I could help out. This stuff is hard, and I'm still learning a lot about it myself even years later. The Rustonomicon is a great read if you haven't already.

CppCon 2022 Best Practices Every C++ Programmer Needs to Follow โ Oz Syed
That is not what UB means. Undefined Behaviour is behaviour that the compiler is allowed to assume will never happen, and which can consequently cause miscompilations due to optimisation passes gone wrong if it does in fact occur in the source code.
It's true that Rust does not have a written specification that clearly delineates what is and isn't UB in a single place. But:
1. UB is impossible in safe code (modulo bugs in unsafe code)
2. There are resources such as the Rustinomicon (https://doc.rust-lang.org/nomicon/) that provide a detailed guide on what is and isn't allowed in unsafe code.
In practice, it's much easier to avoid UB in Rust than it is in C++.

How to write deserializer for custom binary protocol?
However, this is a wide topic out of scope for a Reddit comment, so maybe just read the Rustonomicon. It explains everything about data handling in Rust.

Performance critical ML: How viable is Rust as an alternative to C++
The ownership model & borrow checker makes rust a bit of an awkward language in which to write complex data structures like trees and graphs. It can be done - since you can always use raw pointers & unsafe code when you absolutely need to to treat rust like C. But the language fights you, and the community can get a bit moralistic about this sort of thing. The rust nomicon is a fantastic resource for learning the limits of the borrow checker, and where and how to use unsafe code correctly. You will need unsafe less than you think you will, but sometimes you will have no choice.
