# will substitute :author with the variable author in your file (also works with defaults). 
permalink:      /:author/:slug/
# You need to have this extra permalink_custom_vars array to tell the plugin which substitutions to make
permalink_custom_vars: ['author'] 
# Note that you don't have to include the supported variables in this list as jekyll takes care of that 
# For a complete list of variables jekyll supports, see: https://jekyllrb.com/docs/permalinks/#template-variables

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:

k0kubun

$ cat benchmark.yml
# Config for benchmark_driver.gem
type: command_stdout
name: optcarrot
command: bin/optcarrot --benchmark examples/Lan_Master.nes
metrics_type:
  unit: fps
stdout_to_metrics: |
  match = stdout.match(/^fps: (?<fps>\d+\.\d+)$/)
  Float(match[:fps])
