AOSP-RISCV on Cuttlefish on SpaceMIT K3

It is running. And history is made today, June 2nd, 2026. A couple of things I m pretty certain: For more technical details, please see this github repo. I must confess without claude.ai, this porting would be impossible. When I got some time, I will add some details on the whole journey.

Install Claude Code on RISC-V Linux Hosts

Claude Code is damn powerful! But if you want to install it on RISC-V Linux hosts via the official installer script, you will be greeted with some cold rejection! Below is the workaround method, tested on LicheePi 4A board:

SSH into WSL2 on windows

I have playing with WSL2 (Ubuntu 24.04) and toying with idea maybe it can become my primary linux dev environment and replace the cumbersome vmware player setup. One hiccup I had yesterday was that I could not ssh into wsl2. And apparently even with powerful AI agent (Gemini in this case) I couldn t get it Continue reading "SSH into WSL2 on windows"

Random Thoughts on Investment for Retirement (Dec 2025)

In general I don t want to give investment advices because everyone is different (wealth, objectives, pain tolerance, etc). However, some advices are so safe and sound that I feel it is worthwhile to share, better than watching people around me falling into some simple traps (impulse or intuition trading, coffee shop stock whispering, headline chasing, Continue reading "Random Thoughts on…

Android Cuttlefish Container for Local Development

Android Cuttlefish has made a lot of progress since last time I have messed with them (about 5, 6 years ago!) For example, arm64 host is now supported. WebRTC is finally working. However, certain things are still pretty hideous. Docs are scattered around. Info are hard to find. Simply running a CVD instance locally for Continue reading "Android Cuttlefish Container for Local Development"

Nuances about docker.io on Ubuntu 24.04

I just realized today that the default docker.io package from Ubuntu is seriously limited, compared with the one provided by Docker Inc with their docker-ce (community edition). For example, with the following Dockerfile, the Ubuntu s version of docker would build all intermediate stages, including test-stage, while with Docker Engine packages from docker-ce the test-stage will Continue reading…

Delay Social Security Benefit until Full Retirement Age? Not really!

I keep hearing from so-called professional urging to delay claiming social security benefits until full retirement age, which is 67 right now, or later. The argument is that doing so would maximize the total benefit one receives over the life time. However, no one seems to care about the income gap this strategy creates during Continue reading "Delay Social Security Benefit until Full Retirement…

Geekbench 6 Scores for Intel i9-13900H

Install GCC-14 on ARM64 Debian 11 Bullseye

I need to install the latest gcc on an old ARM64 board, which runs Debian 11 Bullseye. Straightforward of running sudo apt install g++-14 won t find the package. And Internet search does not lead to a simple answer either. There deserves a post.

My Complaints/Wish List for Tesla FSD 12.5.2 (Model Y)

Don t get me wrong. I love FSD. It is one of the most exciting consumer experiences in the recent years. Last such excitement for me probably goes back more than 10 years when I first put my hand on Apple iPhone 2. For me, FSD changes the perception of distance and mobility. It makes San Continue reading "My Complaints/Wish List for Tesla FSD 12.5.2 (Model Y)"
