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.

Fuzzcheck (a structure-aware Rust fuzzer)
I implemented this for proptest + cargo fuzz a while ago as well: https://github.com/diem/diem/blob/main/testsuite/diem-fuzzer/src/lib.rs

Are there any big projects written in Rust without any use of unsafe code?
I believe diem has over 250kLOC and no unsafe code
- the diem coin will be built on a native Facenook Blockchain or is the hypothesis that it can be based on Algorand well founded and has a minimum of sense?

Add experimental fuzz test support for Go 1.17
Just to add, we're a heavy user of fuzzing in Diem[1] and we found a good number of bugs thanks to it : )

Architecture.md
I have a similar advice, but I will go one step further: add README.md to other folders as well. It is dope to have a map of your whole system in an Architecture.md, but it's even more dope to be able to click through it and have submaps of how other components are structured.
Displaying the folder/file structure and explaining what is what is a must. For example: https://github.com/diem/diem/tree/master/consensus#how-is-th...

Show HN: I built a transit travel time map
Super awesome! I like how you just color roads to show time. When you calculate polygons to try and cover the whole area in some 5-10 minute bucket, you can wind up with all sorts of odd holes far away from roads. Keep it simple.

Egregoria is a city simulation with high granularity
A|B Street does some of that, but it is not a game: https://github.com/a-b-street/abstreet

Ask HN: Who is hiring? (December 2022)
Active Travel England | Software Developers and Data Engineer | Full or Part Time | https://www.gov.uk/government/organisations/active-travel-en...
Active Travel England will be developing tools to support evidence-based investment and policies to support sustainable transport. We're hiring 3 roles at present (there will be more jobs in January): https://www.civilservicejobs.service.gov.uk/csr/index.cgi?SI...
We are already working with the transport simulation and scenario development tool A/B Street and the Low Traffic Neighbourhood design tool: https://a-b-street.github.io/docs/ and plan to create new web applications to transform active travel infrastructure design, monitoring and evaluation.
An exciting thing about these jobs from a software engineering perspective is that you will be starting with a relatively blank slate. In the UK we already have tools like https://bikedata.cyclestreets.net and https://www.pct.bike/ but need to go further than this. Long term, the 7 strong Data and Digital team that you will be part of will develop a comprehensive map based design support tool to provide data of the type in BikeData (and more datasets), drawing tools, and automated assessment of proposed interventions.
These opportunities will enable you to shape the future of tools for active travel investment and policy in England and, because the software develop as part of these roles will be open source, beyond.
These high profile jobs will have a large impact, see here for context: https://twitter.com/Chris_Boardman/status/159648662743800217...

34 extremely good websites(to have fun) that most people probably don't know about - dancing robots you can fling, 180 websites in 180 days, hot or not for generative art, draw auroras
https://github.com/a-b-street/abstreet - project to plan, simulate, and communicate visions for making cities friendlier to people walking, biking, and taking public transit.

Transit route mapping
I've not heard about remix before, but some of its functionality seems similar to A/B Street which is aimed at comparing the effects of proposed changes on city traffic.

GitHub actions for my project to automatically compile for Linux/Windows and create Windows-installer.
Thanks for sharing! Are you signing the Windows executable to get rid of "unverified developer" warnings? Inno lists signing as a feature, but I've yet to come across a simple guide on how to build and sign Rust binaries using Github actions. (Some references here])

Are there any big projects written in Rust without any use of unsafe code?
A/B Street, which comprises a UI library, lots of data import pipelines, and traffic simulation. 100k LoC, the only unafe is to make system calls through glow

Prettymaps: Small Python library to draw customized maps from OpenStreetMap data
Especially if you're trying to clip your entire map to some boundary, rendering the ocean is hard. https://github.com/a-b-street/abstreet/issues/32 has some examples of "flooded" maps when the heuristics get the inversion wrong. https://github.com/a-b-street/abstreet/blob/9761373c4b215485... is my incomplete attempt to deal with these partial multipolygons.
What are some alternatives?
prettymaps - A small set of Python functions to draw pretty maps from OpenStreetMap data. Based on osmnx, matplotlib and shapely libraries.
tilemaker - Make OpenStreetMap vector tiles without the stack
osm-renderer - OpenStreetMap raster tile renderer written in Rust
grid2demand - A tool for generating zone-to-zone travel demand based on grid zones and gravity model
awesome-vector-tiles - Awesome implementations of the Mapbox Vector Tile specification
vsketch - Generative plotter art environment for Python
WRF - The official repository for the Weather Research and Forecasting (WRF) model
owid-grapher - A platform for creating interactive data visualizations
Openstreetmap - The Rails application that powers OpenStreetMap
go-concise-encoding - Golang implementation of Concise Binary and Text Encoding
hyperspace - Metaverse Hyperspace Chain, Hybrid PoW/PoS consensus full node with EVM compatible VM and smart tokens(FT/NFT).
cardano-serialization-lib - This is a library, written in Rust, for serialization & deserialization of data structures used in Cardano's Haskell implementation of Alonzo along with useful utility functions.
