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.

Ffmprovisr – Making FFmpeg Easier
You can do that with ffmpeg, but the output isn't ideal
I'd use gifski: https://gif.ski/

Free High-Quality Gif Maker
If image quality is more important than size then give Gifski a try. No idea how it's on win but on a mac it's my default GIF solution.

I imported an mp4 video into premiere pro. Then exported there with gif. Now I see these weird dots in the picture/video. Can someone explain to me why this is and how I can fix it? I appreciate any help!
To make a legitimate high quality GIF, you can try Gifski. YMMV, I haven't tried using it yet but that's what some of the people at highqualitygifs say they use to make actual GIFs.

Tree Borrows - A new aliasing model for Rust
It looks like .get_disjoint_mut() from slotmap failed under stacked borrows, but seems to pass under tree borrows

Indexing vs Smart Pointers
I think slotmap is meant to solve this exact issue. Basically when you insert into a collection you get an Id:Version tuple as key. When you reuse a slot, next time the key will be Id:Version+1 and when you try to access the removed value by using Id:Version, it will return None. You can think about it as delayed invalidation.

Hey Rustaceans! Got a question? Ask here (5/2023)!
Dunno about existing implementations, but it looks like it's a feature they'd accept: https://github.com/orlp/slotmap/issues/73

Unsafe is a bad practice?
It's actually quite easy.
- Rust is more portable than C for pngquant/libimagequant

Hey Rustaceans! Got an easy question? Ask here (50/2021)!
You can use either slot map or slab to side step rust borrow checker. Example https://github.com/orlp/slotmap/blob/master/examples/rand_meld_heap.rs

Rust data structures with circular references
I don't know, only have some theories.
1. The name isn't particularly catchy or descriptive. It is the correct name for the data structure, but not too many people know the data structure.
2. People don't even know what they're missing. It's not a very Google-able problem to begin with. Slotmap provides an interesting solution to (circular) ownership and safe allocator / weak pointer design problems, but people don't recognize that they're having them or that slotmap could help.
As an example of this, the doubly linked list example (https://github.com/orlp/slotmap/blob/master/examples/doubly_...) can safely remove nodes from the linked list given their handle, in O(1), even from the middle, completely safely and correctly, even in the presence of double deletions or ABA memory re-use. You can't replicate this with just pointers, without introducing heavy refcounting solutions.

Is it possible to write anything using 100% safe Rust?
Nope, it's perfectly safe: https://github.com/orlp/slotmap/blob/master/examples/doubly_linked_list.rs.

Syncing HashMap values amongst User
I think keeping the relationship between child and parent elements in the node graph might be better accommodating better via a psuedo-ECS system, see https://www.reddit.com/r/rust/comments/cnjhup/idiomatic_way_to_reference_parent_struct/. The https://github.com/orlp/slotmap crate looks promising. I think I'm just going to ditch the global shared HashMap in favor of something that can better accommodate child/parent relations.

Beginner question: does it become easier to write datastructures with complex ownership semantics?
I think the slotmap crate is similar to what you're trying to write: https://github.com/orlp/slotmap
