Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

echo "Current status: $current"

if [ "$current" == "$swapped" ]
then
  echo "Making caps and escape WORK NORMALLY"

Switching between AHCI and RAID on the Dell XPS 15 (9560)

This guide likely applies to other models and, potentially, even laptops from other OEMs that have NVME drives. However, I've only tested this on my Dell XPS 15 (9560) with the OEM Windows installation from the Signature Edition model.

Switching from RAID to AHCI

Switching from RAID to AHCI is significantly simpler than switching from AHCI to RAID. All that's needed is a successful boot to Safe Mode.

1. To set the default boot mode to Safe Mode, use msconfig.exe or open an admin cmd/PowerShell window and run:

mattdymott

// CollisionResponse option on PhysicsShape must be set to CollideRaiseCollisionEvents.

[UpdateInGroup(typeof(PhysicsSystemGroup))]
[UpdateAfter(typeof(PhysicsSimulationGroup))]
public partial struct CalculateDetailsTest_PhysicsEventSystem : ISystem
{
    [BurstCompile]
    public void OnCreate(ref SystemState state)
    {

I like to manage dotfiles without having to mess with silly symlinks or having
to install/configure specific dotfile managament tools. So here's what I did:
 
$ cd ~
$ git init .
$ echo '*' > .gitignore                   # ignore all files by default
$ echo '!.bashrc' >> .gitignore           # ...and then tell git what files not to *not* ignore
$         # ...add other files you may want to track to *not* ignore
$ git add .bashrc                         # now actually add the files to git
$ git add .gitignore                      # add the .gitignore to git

# Save the $timeout and $timeout_style values set by /etc/grub.d/00_header

cat << EOF
set timeout_bak=\${timeout}
set timeout_style_bak=\${timeout_style}
EOF

Finding hard-coded credentials in your code
Hopefully you’re excited about deploying credentials to EC2 that are automatically rotated.  Now that you’re using Roles, a good security practice would be to go through your code and remove any references to AKID/Secret.  We suggest running the following regular expressions against your code base:

Search for access key IDs: (?<![A-Z0-9])[A-Z0-9]{20}(?![A-Z0-9]).  In English, this regular expression says: Find me 20-character, uppercase, alphanumeric strings that don’t have any uppercase, alphanumeric characters immediately before or after.
Search for secret access keys: (?<![A-Za-z0-9/+=])[A-Za-z0-9/+=]{40}(?![A-Za-z0-9/+=]).  In English, this regular expression says: Find me 40-character, base-64 strings that don’t have any base 64 characters immediately before or after.
If grep is your preferred tool, run a recursive, Perl-compatible search using the following commands
