kim

kim is a Kubernetes-aware CLI that will install a small builder backend consisting of a BuildKit daemon bound to the Kubelet's underlying containerd socket (for building images) along with a small server-side agent that the CLI leverages for image management (think push, pull, etc) rather than talking to the backing containerd/CRI directly. kim enables building images locally, natively on your k3s cluster.

bmc-cache

BMC (BPF Memory Cache) is an in-kernel cache for memcached. It enables runtime, crash-safe extension of the Linux kernel to process specific memcached requests before the execution of the standard network stack. BMC does not require modification of neither the Linux kernel nor the memcached application. Running memcached with BMC improves throughput by up to 18x compared to the vanilla memcached application.
