Btrfs guide to set up an LUKS-encrypted btrfs raid volume with included maintenance & recovery guide

Encrypted Btrfs storage setup and maintenance guide

Initial setup with LUKS/dm-crypt

This exemplary initial setup uses two devices /dev/sdb and /dev/sdc but can be applied to any amount of devices by following the steps with additional devices.

Create keyfile:

dd bs=64 count=1 if=/dev/urandom of=/etc/cryptkey iflag=fullblock
chmod 600 /etc/cryptkey

Unlock LUKS full disk with USB stick

Configuration for passwordless root filesystem

Source: https://www.howtoforge.com/tutorial/passwordless-encryption-of-linux-root-partition/

The process of entering the passphrase at boot time will now be automated using an USB memory stick. Instead of using a passphrase , the secret key on the USB will decrypt the encrypted volumes. Connect an USB stick to the VM and locate it using the dmesg command. It is detected as /dev/sdb in my VM.

The secret key of 8192 random byte is extracted from the usb stick using the dd command.

dd if=/dev/sdb of=/root/secret.key bs=512 skip=4 count=16

Note, you'll need to be running on a Windows domain with Visual Studio debugging in IIS Express for this to work.

Setup

In launchSettings.json, you'll want to modify iisSettings by turning on windowsAuthentication:

How to upgrade [Lenovo] NVMe SSD firmware on Linux

The instructions were tested on a Lenovo X1 Carbon 5th Gen (X1C5) on Arch Linux but should be applicable to other Lenovo models and Linux distributions.

BACKUP YOUR DATA! I created a bootable Ubuntu Image like this:

$ sudo sh -c 'curl --location --silent --fail "http://releases.ubuntu.com/18.04/ubuntu-18.04.1-desktop-amd64.iso" | pv > /dev/<your-usb-drive>'
# note that pv is only there to show progress, it is perfectly fine to redirect curl to the usb drive directly.

then I booted from this drive by pressing F12 on reboot and dumped my NVMe disk to an external hard drive like this:

Building TensorFlow from source

Building TensorFlow from source (TF 2.3.0, Ubuntu 20.04)

Why build from source?

The official instructions on installing TensorFlow are here: https://www.tensorflow.org/install. If you want to install TensorFlow just using pip, you are running a supported Ubuntu LTS distribution, and you're happy to install the respective tested CUDA versions (which often are outdated), by all means go ahead. A good alternative may be to run a Docker image.

I am usually unhappy with installing what in effect are pre-built binaries. These binaries are often not compatible with the Ubuntu version I am running, the CUDA version that I have installed, and so on. Furthermore, they may be slower than binaries optimized for the target architecture, since certain instructions are not being used (e.g. AVX2, FMA).

So installing TensorFlow from source becomes a necessity. The official instructions on building TensorFlow from source are here: ht

What is the standard Python docstring format?

Formats

Python docstrings can be written following several formats as the other posts showed. However the default Sphinx docstring format was not mentioned and is based on reStructuredText (reST). You can get some information about the main formats in that tuto.

Note that the reST is recommended by the PEP 287

There follows the main used formats for docstrings.
