Learned Linux in just two weeks—starting with Arch Linux—and successfully replaced my previous macOS (2020 m1 macbook) workflow by repurposing an old Dell OptiPlex 7040 (2015 product). Gained hands-on experience with essential Linux tools such as
udev, virtual machines,bash,nvim,tmux,thorium,pacman,systemdandlinux kerneletc.
My linux experience:
arch-linux(it record my journey of using arch linux), asahi-linux(using fedora linux in M1 macbook as server with minimalist sever style), arch-linux-qemu(Learned Virtual Machine using KVM, VMware Workstation, etc )
-
self learned a trick to use VMware img and then convert it to kvm favora img qemu-img convert -O qcow2 test.vmdk test-better.qcow2 (it improve the linux lab about 80% responsiveness time in terms of CLI usage)
-
Arch Linux (Catchos)
- Used performance-optimized distribution necessitates recompiling essential Arch Linux packages for x86-64-v3
- Adapted various sched-ext schedulers for improved responsiveness(SSD)
- latest linux keneral with kvm enabled and patched
- Latest BBRv3 (TCP congestion control algorithm) by Google
-
Fedora Linux → Macbook pro m1 (dual boot)
