Workarounds for building Q on 8GB RAM environment:

1. At the start of the build:
[ 99% 138/139] /mnt/ssd/aosip/out/soong/.bootstrap/bin/soong_build /mnt/ssd/aosip/out/soong/build.ninja
This used to take around 30mins, after enabling zram now it takes around 30secs (thanks to @kdrag0n for the zram idea) which is on par with what happens in 16GB RAM building environments

sudo apt install zram-config for installing zram-config package
sudo nano /etc/fstab and add a # in front of the swap disk if you have one and then reboot
After booting cat /proc/swaps to check if zram is enabled or not

Getting a USB device to show up in a Docker container on OS X

Some background

I was trying to get the Arduino IDE to work inside a Docker container on OS X. I was able to get the IDE working (see Getting X11 GUI applications to work on OS X with Docker), but I could not figure out how to make the USB port for the Arduino visible.

The solution

I first tried to directly map hardware serial port into the Docker container, doing something like this:

setup variables for commands

echo -e "\n
export image=redroid/redroid:11.0.0-amd64
export image_tar=${HOME}/redroid:11.0.0-amd64" >> ${HOME}/.bashrc
source ${HOME}/.bashrc

Solved step

# install dependencies,it's easy here
sudo apt install -y cmake
# install basic tools
sudo apt install -y build-essential autoconf libtool pkg-config

# clone from github and install it,I installed v1.51.1 here
git clone --recurse-submodules -b v1.51.1 https://github.com/grpc/grpc
cd grpc
