Change root password in MariaDB Docker container running with docker-compose

Override the entrypoint in docker-compose.yml for the MariaDB Docker container by adding:

entrypoint: mysqld_safe --skip-grant-tables --user=mysql

The start up the Docker Compose stack:

# This script is based on https://unix.stackexchange.com/revisions/480191/9 .
# The following changes proved to be necessary to make it work on CentOS 7:
#  * removed disk info (model, size) - not very useful, might not work in many cases.
#  * using "bw" instead of "bw_bytes" to support fio version 3.1 (those availible through yum @base)
#  * escaping exclamation mark in sed command
#  * the ".fiomark.txt" is not auto-removed

Arch Linux ARM 64 on Raspberry Pi 3 B+ With Full Disk Encryption And SSH Unlock: 2018 Edition

There are multiple ways to get a full disk encrypted arch linux system on raspberry. In this tutorial, we will install a 64-bit arch linux armv8 system, using dropbear as ssh server for remote pre-boot unlocking of the root filesystem. However, it will still be possible to unlock and use the pi as usual, with a keyboard and monitor. We will also create an unencrypted partition in the installation process, usable as a rescue system.

Differences to the 32-bit arch linux arm version:

• probably better performance
• can run 64-bit software
• comes without the proprietary video-driver blobs

Using VAAPI's hardware accelerated video encoding on Linux with Intel's hardware on FFmpeg and libav

Hello, brethren :-)

As it turns out, the current version of FFmpeg (version 3.1 released earlier today) and libav (master branch) supports full H.264 and HEVC encode in VAAPI on supported hardware that works reliably well to be termed "production-ready".

Installing

Install FFmpeg with homebrew. You'll need to install it with a couple flags for webm and the AAC audio codec.

brew install ffmpeg --with-libvpx --with-libvorbis --with-fdk-aac --with-opus
