Small, quick guide to set up Manjaro on the XPS 15 9560
# 1. First of all of course get Manjaro:
https://manjaro.org/get-manjaro/
# I recommend using Etcher to copy the image to your USB:
https://etcher.io/
# 2. Before installing make sure:
# - Secure boot is disabled in BIOS
# - Your SSD, HDD or NVME drive is set to AHCI instead of RAID
# - Fastboot should be on Auto or minimal, but this shouldn't matter to much

Resize root partition (or how to remove the default /home partition) on CentOS 7 online

Resize root partition (or how to remove the default /home partition) on CentOS 7 online

This process requires that you are able to ssh OR log in locally using the root user account and that no services be running as users out of /home on the target machine.

The examples are from a default installation with no customization-you NEED to know what you're working with for volumes/partitions to not horribly break things.

By default, CentOS 7 uses XFS for the file system and Logical Volume Manager (LVM), creating 3 partitions: /,/home and swap.

NOTE: If you want to be sure that nothing is writing to /home you can either modify the host to boot into single-user mode OR try to use the systemctl isolate runlevel1.target command to switch (not tested! should work).

Cryptographic Best Practices

Cryptographic Best Practices

Putting cryptographic primitives together is a lot like putting a jigsaw puzzle together, where all the pieces are cut exactly the same way, but there is only one correct solution. Thankfully, there are some projects out there that are working hard to make sure developers are getting it right.

The following advice comes from years of research from leading security researchers, developers, and cryptographers. This Gist was [forked from Thomas Ptacek's Gist][1] to be more readable. Additions have been added from
