What Desktop Environment do you use?
I think there might be some confusion in this poll and thread -- COSMIC is the name of both a suite of components in Pop_Shell, which modifies (but does not replace) GNOME shell components like the dock and workspaces, as well as a full-fledged desktop environment that replaces GNOME.

Ask HN: What Happened to Elm?
system76 is using it to develop their new cosmic desktop environment for linux. The code is here https://github.com/pop-os/cosmic-epoch
We'll see how it starts panning out this year or next.

Just moved to Pop OS! from Fedora 37 beta. I want to set GRUB_CMDLINE_LINUX_DEFAULT="i915.enable_psr=0" , how do I do this?
I heard that the Iced version of COSMIC will allow horizontal and vertical workspaces: https://github.com/pop-os/cosmic-epoch/issues/53

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?
dream - Tidy, feature-complete Web framework
firecracker - Secure and fast microVMs for serverless computing.
apprun - AppRun is a JavaScript library for developing high-performance and reliable web applications using the elm inspired architecture, events and components.
podman - Podman: A tool for managing OCI containers and pods.
xdg-desktop-portal-hyprland - xdg-desktop-portal backend for Hyprland
wsl-vpnkit - Provides network connectivity to WSL 2 when blocked by VPN
elm-canvas - A canvas drawing library for Elm
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/
rescript-compiler - The compiler for ReScript.
sysbox - An open-source, next-generation "runc" that empowers rootless containers to run workloads such as Systemd, Docker, Kubernetes, just like VMs.
azurelinux - Linux OS for Azure 1P services and edge appliances
