  • Fixed an A2 Error on ASUS Rampage V Extreme

    I have been a bit obsessed with PCs since my parents bought me my first PC, a 386DX with 4MB of memory, almost 30 years ago. Recently one of my friend was selling his crypto mining rig, and I bought the essential parts to start building a new server: I bought a new fan for […]

  • Ubuntu Server 20.04 on ThinkPad W520

    10 years ago, I would dream for a ThinkPad W520 laptop: imagine 4 cores, 8 threads, 32GB memory and 160GB SSD in 2012! I saw one of these old battleship-class laptops Gumtree the other day so I bought it without much hesitation – It’s still very good as a mini server even in 2022. In […]

  • Installation of Fedora 36 on Dell XPS 13 9380

    Installation of Fedora 36 on Dell XPS 13 9380

    I happened to have acquired a used Dell XPS 13 9380, which is a nice little ultrabook with Intel 8th gen i7 CPU, 16GB memory(not upgrade-able), 512GB nvme SSD and a beautiful 13″ 4k screen. It has Windows 10 installed. Of course I have no intention to continue to use the stock Windows 10. At […]

  • Mining Ethereum with Multiple AMD 6600 XT Cards on Ubuntu Linux

    Warning: Ethereum(ETH) will migrate to PoS(Proof of Stake) algorithm in near future, maybe in a year. So jumping into ETH mining now might not be profitable. Also, I encourage crypto mining with renewable energy sources and a Tesla PowerWall 2 is just a few RTX 3090s away 🙂 Note: This is a follow-up for my […]

  • My nVidia RTX 3080 ThermalRight Upgrade

    Recently I traded my 2x Gigabyte RTX 3070 for a Aorus Masters RTX 3080 for a set of various reasons: For Ethereum crypto mining, a 3080 can achieve ~100MHps, which is very close to what 2x 3070 can do 1x 3080 definitely consumes less power than 2x 3070 If I play games or VR, only […]

  • Google Nest Wifi: A Speaker With Mesh Wifi

    I have been using a NetGear Nighthawk R7000 for many years, time for an upgrade. The Google Nest Wifi is very easy to setup, only need to connect the Nest Wifi router to existing router/modem and the rest can be done on a phone with Google Home app. Here are some good stuff I got […]

  • Kubernetes at Home on Raspberry Pi 4, Part 3

    Continue from part 2, this is mostly about installing ingress controller. In short, an ingress controller is like a single entry point for all ingress connections into the cluster. The reason I chose Flannel over other CNIs is that it’s lightweight and not bloated with features. I would like to keep the Pi 4s easy […]

  • Kubernetes at Home on Raspberry Pi 4, Part 2

    Continue from part 1 It’s recommended to change all Pi’s password also run ssh-copy-id [email protected] to enable SSH public key login. There are lots of steps to prepare before kubeadm is installed, so I made this ansible repository to simplify this repeating process. Please see here. The ansible role will do the following tasks: set […]
