Cloning a Ubuntu boot SSD to NVME

Getting short of space on a 120G boot/root SSD on Ubuntu Server, decided to replace it with a bigger NVME (IDE) 250G drive.

Using the latest Clonezilla, the process was really painless. After cloning, there was still over 100G unallocated space on the larger drive for expansion of a new parition. The paritions of the clone had the same disk UUIDs and flags as the original.

Checked disk and partition sizes using lsblk.
Downloaded latest Stable iso from https://clonezilla.org/downloads.php.
Get a 1G or more USB stick and burn the iso onto it using Startup Disk Creator.
Installed the NVME drive onto the motherboard.

Linux Desktop on Apple Silicon in Practice

I bought M1 MacBook Air. It is the fastest computer I have, and I have been a GNOME/GNU/Linux user for long time. It is obvious conclusion that I need practical Linux desktop environment on Apple Silicon.

Fortunately, Linux already works on Apple Silicon/M1. But how practical is it?

Two native ports exist.

Android emulator. Reduce CPU usage on MacOS

I wasn't able to shut the audio off with the config.ini file, but only with the -noaudio cmd line argument to qemu. However, with Android Studio 3.2, you can't add custom arguments to the emulator, so I made this:

In the emulator dir of the Android SDK, in my case ~/Android/Sdk/emulator/

mv emulator emulator.orig Make a bash script called emulator with the content:

#!/bin/bash

	#!/usr/bin/env bash

	# Builds mpv & mpv.app on Apple silicon Macs.
	# Run this script from the root directory of the mpv repo.

	# if anything fails, gtfo
	set -ex

	meson setup build
	meson compile -C build
