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: Looking for a project to volunteer on? (November 2023)
Seeking: https://github.com/fwsGonzo/libriscv
This is a C++ RISC-V emulator that focuses on isolating a single process, aka userspace emulation. I am currently working mostly on binary translation, and recently I have made a push to move it from experimental state to fully supported. Another experimental feature is embedding libtcc and using that for binary translation. It is fairly fast to compile, and gives decent speedups. The challenge is what to do now that (perhaps) some low hanging fruits have been picked.

Writing a Tiny RISC-V Emulator [video]
I definitely recommend people to consider the base ISA of RISC-V if they want to try to implement a CPU or even full-system emulation. I understand that implementing a GameBoy emulator might be more attractive because you are working towards something graphical, but you can definitely get something similar with RISC-V, eg. Doom (SDL example: https://github.com/fwsGonzo/libriscv/tree/master/examples/do...)

C++17 RISC-V RV32/64/128 userspace emulator library
There is a doom emulation demo here now: https://github.com/fwsGonzo/libriscv/tree/master/emulator/do...
You will need to add the shareware doom1.wad yourself. :)

Recreating Real-World Terrain with React, Three.js and WebGL Shaders
Nice writeup, I always like it when the shaders are highlighted like this. I got started in a similar way 7 years ago and have been making 3D terrains with THREE.js & WebGL since.
The real fun begins when you need to implement some sort of Level-of-Detail system and streaming in data to give the illusion of high detail everywhere without sacrificing performance.
Last year I released an open-source framework (https://github.com/felixpalmer/procedural-gl-js) for creating 3D terrains for web applications, you can see Uluru here: https://www.procedural.eu/map/?longitude=131.036&latitude=-2... (unfortunately the aerial imagery from our default provider isn't as high resolution as other places in Europe)

Visualization of 40M Cell Towers
Great visualization and approach with compressing the tile data. Do you have a comparison of how much smaller the payload ends up being compared to simply sending PNG files?
I use PNGs to encode elevation data in my 3D mapping library (https://github.com/felixpalmer/procedural-gl-js/) and this does a pretty good job of compressing the data, for example in the ocean the PNG files are also very small as the image is mostly black. Different use case I now as your data is much more sparse, but I wonder how close the PNG compression would be compared to your approach.

React Component for 3D Maps
Yeah, the React parts of this are very minimal. I'm not really sure what using it gets you, since it just manages a single div.
The _actual_ library that does all the work is here: https://github.com/felixpalmer/procedural-gl-js

Ask HN: What Are You Working On?
- Tiny filesize means library is parsed fast. Package size is less than THREE.js thanks to code stripping
Check it out on Github: https://github.com/felixpalmer/procedural-gl-js/
