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.

ToyDB: A Rust learning adventure, fun open-source project, and database learning resource for the community
This is great, but you might want to consider a different name. There's already a Rust project called ToyDB, and it's a distributed database with a Raft log, SQL, disk persistence, ACID transactions, etc. It's under active development (though the developer now works at Cockroach Labs), and has 5K stars on GitHub, so I think they have the right to the name.

Any ideas for resume
Build something youβd like to learn about. Things Iβve considered replicating: A distributed database (see https://github.com/erikgrinaker/toydb), an interpreter (crafting interpreters is a good book), a Ray tracer (http://raytracerchallenge.com/), an RPC compiler and framework, a simpler neural network framework ( https://github.com/pjreddie/darknet)β¦

Which software do you think would be essential for the RISC-V to be succesful ?
Hilariously, I was trying out ToyDB on the Lichee-RV recently. While it does compile and run the five-node example setup (and memory usage is surprisingly low, which is a plus considering the 0.5GB of RAM), performance is three orders of magnitude lower than on a desktop x86 PC. Some of that is due to just having a single core run 5 nodes, some is due to the lower clock speed and slower memory, and some is due to slower storage (SD card). I don't think that explains everything, so I may investigate that later.

Converting the Kernel to C++
A recent practical example of the former: the fish shell re-wrote incrementally from C++ to Rust, and is almost finished https://github.com/fish-shell/fish-shell/discussions/10123
An example of the latter: c2rust, which is a work in progress but is very impressive https://github.com/immunant/c2rust
It currently translates into unsafe Rust, but the strategy is to separate the "compile C to unsafe Rust" steps and the "compile unsafe Rust to safe Rust" steps. As I see it, as it makes the overall task simpler, allows for more user freedom, and makes the latter potentially useful even for non-transpiled code. https://immunant.com/blog/2023/03/lifting/

Best tools to convert code between languages?
But not all transpilers are between languages where at least one of them is designed to be transpiled. For example, c2rust can transpile, as the name suggests, C to (ugly, unsafe) Rust. A while ago there was a Java -> C compiler in GCC (GCJ), but it's pretty out of date now.

I do not know about your specific issue but you may be interested by https://github.com/immunant/c2rust

Rewrite in Rust or Use Rust-bindings
You should also consider using C2Rust (they're even working on C -> safe Rust translation)

There's commits in the last hour, so at least some signal of life.

Writing an OS in Rust to run on RISC-V
This is arguably already the state of things.
Rust might get compiled down through MIR, down through LLVM IR, down to assembly or wasm... which then might be JIT or AOT (re)compiled into other bytecodes... which might perhaps be decompiled back up to C... and C might be retranslated back to horrific unsafe-spamming Rust by the likes of https://c2rust.com/. We've come full circle!
The main issue is that retranslating high level languages into other high level languages isn't something that there's actually a lot of demand for, especially commercially, especially given the N x M translation matrix going on. So a lot of the projects "stabilize" (get abandoned). And automatically translating between the idioms of those languages gets even nastier in terms of matrix bloat.
Well, you've got stuff like MSIL and JVM bytecodes which are higher level, and preserve more type information, and can be compiled to / decompiled from while still preserving more structure, but they still form competing incompatible ecosystems.

Will Carbon Replace C++?
That's the wrong direction. What's needed are intelligent converters which convert less-strict languages to more-strict ones.
Non-intelligent converters just make a mess. Here's c2rust.[1]
Classic C++ to modern C++, plus a compiler flag to lock out all the old unsafe stuff, would be an achievement.

Red Black Tree in Rust
Well, technically, it's not hard to build such data structures. If you are willing to liberally use raw pointers, UnsafeCell, MaybeUninit and ManuallyDrop, then you can more-or-less write C-equivalent code in unsafe Rust. (there are even transpilers from C to Rust)
