Ninja SRE is a retro-styled educational incident-response game for OpenStack administrators and site reliability engineers.
Investigate 56 simulated incidents spanning Linux, networking, Neutron, OVN/OVS, Nova, Placement, RabbitMQ, databases, Cinder, Ceph, Octavia, SR-IOV and hardware offload. Follow evidence across a simulated jump host, controllers, computes, storage nodes and virtual machines, then repair and validate the fault before declaring the incident resolved.
The game is written in C, renders its own 1280x720 software framebuffer, supports Wayland and X11 through SDL2, and requires no special GPU.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
On Arch Linux, snap can be installed from the Arch User Repository (AUR). The manual build process is the Arch-supported install method for AUR packages, and you’ll need the prerequisites installed before you can install any AUR package. You can then install snap with the following:
git clone https://aur.archlinux.org/snapd.git
cd snapd
makepkg -si
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
If AppArmor is enabled in your system, enable the service which loads AppArmor profiles for snaps:
sudo systemctl enable --now snapd.apparmor.service
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install Ninja SRE - Cloud Incident Simulator, simply use the following command:
sudo snap install ninja-sre
Browse and find snaps from the convenience of your desktop using the snap store snap.
