WARNING: Performance and battery life may vary depending on system and usage.

01-howdy-3-face-unlock-pam

Enable PAM authentication via face recognition after installing Howdy v3 beta.

01-grub-k8s-cgroup-v2

Custom GRUB configuration for Kubernetes cgroup v2.

01-awesome-tcp-network-tuning

Normal TCP/network tuning for Linux servers.

02-controversial-tcp-network-tuning

Contains controversial and potentially dangerous TCP/network settings. Do NOT apply directly to your system.

03-m1-macbook-arm-linux-tcp-network-tuning-for-daily-use

TCP tuning and power-saving configuration for M1 MacBooks running Linux.

• May slightly reduce performance but prioritizes battery life
• Expected runtime: 10–13 hours
• On my MacBook (battery health 95%, conservative usage), achieved 10–11 hours

Includes: TCP tuning Powersave options Kernel cmdline tweaks CPU governor configuration Scheduler rules

04-make-custom-laptop-governor

Custom laptop CPU governor developed for better energy efficiency.

• Conservative-style policies with smarter frequency scaling
• Achieves 1–2 hours longer runtime than project 03-m1-macbook-arm-linux-tcp-network-tuning-for-daily-use

Includes:

• Systemd service for CPU governor
• Laputil C tool for CPU frequency management
• Scripts for AC headers and DKMS integration

05-criu-based-application-recovery

Recover application states using CRIU (Checkpoint/Restore in Userspace)

• Useful after system hibernation or crashes
• Includes scripts to suspend and restore processes

06-storage-optimization

SSD optimization via filesystem trimming

• Improves write performance and storage health
• Extends SSD lifespan compared to untrimmed setups

Includes:

• Systemd timer and service for automated fstrim

07-sysctl-for-screen-mirroring

Sysctl for screen mirroring clients(e.g. XRDP, Sunshine)

• Improves Buffering on client
• Has two different configuration for server and client
