Enable PCIe 3.0 speeds for NVMe SSDs on Dell OptiPlex 3060

Out of the box, any M.2 NVMe SSDs connected to the Dell OptiPlex 3060 runs at PCIe Gen 2.0 speeds (Max 5 GT/s; 2 GB/s) so the speed tests look like this:

However, after this BIOS mod, the SSD can reach PCIe Gen 3.0 speeds (Max 8 GT/s; 3.9 GB/s) so the speed tests look like this:

Risk Assessment of GitHub Copilot

0xabad1dea, July 2021

this is a rough draft and may be updated with more examples

GitHub was kind enough to grant me swift access to the Copilot test phase despite me @'ing them several hundred times about ICE. I would like to examine it not in terms of productivity, but security. How risky is it to allow an AI to write some or all of your code?

Ultimately, a human being must take responsibility for every line of code that is committed. AI should not be used for "responsibility washing." However, Copilot is a tool, and workers need their tools to be reliable. A carpenter doesn't have to

Completely reset TCC services database in macOS

Note: Both the system and individual users have TCC databases; run the script as both
      a user and as root to completely reset TCC decisions at all levels.

2018-08-15: Resetting the 'Location' service fails; unknown cause
2018-08-16: Confirmed the 'All' service does not really reset _all_
            services, so individual calls to each service is necessary.
