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.

Release: WasmEdge 0.12 and 0.12.1
https://github.com/second-state/microservice-rust-mysql
https://github.com/WasmEdge/wasmedge-db-examples
https://github.com/WasmEdge/wasmedge_hyper_demo
WasmEdge is already one of the smallest and most efficient Wasm runtimes out there. It embeds into libsql (SQLite on the server!) to execute user definited functions to perform complex tasks like HTTPS web services & AI inference from SQL statements! https://wasmedge.org/docs/embed/use-case/libsql/
The WasmEdge C++ and Rust SDKs allow host applications to embed Wasm functions asynchronously. It is critically important in many applications where the embedded Wasm function is simply not allowed to block the execution of the host applications. https://github.com/second-state/wasmedge-rustsdk-examples/bl...
Asynchronous host SDKs are complex and a lot of work still remains. We are continuously improving it with our end user and partner communities.

Rust microservices in server-side WebAssembly
The example below, from the microservice-rust-mysql demo app, shows how to create a web server in hyper for WasmEdge. The main listening loop of the web server is as follows:

Maestro: A Linux-compatible kernel in Rust
Isn't gVisor kind of this as well?
"gVisor is an application kernel for containers. It limits the host kernel surface accessible to the application while still giving the application access to all the features it expects. Unlike most kernels, gVisor does not assume or require a fixed set of physical resources; instead, it leverages existing host kernel functionality and runs as a normal process. In other words, gVisor implements Linux by way of Linux."

Faster Filesystem Access with Directfs
This sort of feels like seeing someone riding a bike and saying: why don’t they just get a car? The simple fact is that containers and VMs are quite different. Whether something uses VMX and friends or not is also a red herring, as gVisor also “rolls it own VMM” [1].

OS in Go? Why Not
There's two major production-ready Go-based operating system(-ish) projects:
- Google's gVisor[1] (a re-implementation of a significant subset of the Linux syscall ABI for isolation, also mentioned in the article)
- USBArmory's Tamago[2] (a single-threaded bare-metal Go runtime for SOCs)
Both of these are security-focused with a clear trade off: sacrifice some performance for memory safe and excellent readability (and auditability). I feel like that's the sweet spot for low-level Go - projects that need memory safety but would rather trade some performance for simplicity.

Tunwg: Expose your Go HTTP servers online with end to end TLS
It uses gVisor to create a TCP/IP stack in userspace, and starts a wireguard interface on it, which the HTTP server from http.Serve listens on. The library will print a URL after startup, where you can access your server. You can create multiple listeners in one binary.

How does go playground work?
The playground compiles the program with GOOS=linux, GOARCH=amd64 and runs the program with gVisor. Detailed documentation is available at the gVisor site.

Multi-tenancy in Kubernetes
You could use a container sandbox like gVisor, light virtual machines as containers (Kata containers, firecracker + containerd) or full virtual machines (virtlet as a CRI).
What are some alternatives?
postgres-wasm - A PostgresQL server running in your browser
firecracker - Secure and fast microVMs for serverless computing.
webvm - Virtual Machine for the Web
podman - Podman: A tool for managing OCI containers and pods.
SSVM - WasmEdge is a lightweight, high-performance, and extensible WebAssembly runtime for cloud native, edge, and decentralized applications. It powers serverless apps, embedded functions, microservices, smart contracts, and IoT devices.
wsl-vpnkit - Provides network connectivity to WSL 2 when blocked by VPN
podman-wasm
kata-containers - Kata Containers is an open source project and community working to build a standard implementation of lightweight Virtual Machines (VMs) that feel and perform like containers, but provide the workload isolation and security advantages of VMs. https://katacontainers.io/
dapr-wasm - A template project to demonstrate how to run WebAssembly functions as sidecar microservices in dapr
sysbox - An open-source, next-generation "runc" that empowers rootless containers to run workloads such as Systemd, Docker, Kubernetes, just like VMs.
