“Oh! I have slipped the surly bonds of EarthPilot Officer John Gillespie Magee Jr. – Killed 11 December 1941 (age 19)
And danced the skies on laughter-silvered wings;
climbed,and joined the tumbling mirth
of sun-split clouds, — and done a hundred things
You have not dreamed of — wheeled and soared and swung
High in the sunlit silence. Hov’ring there,
I’ve chased the shouting wind
my eager craft through footless halls of air
Up, up the long, delirious, burning blue
I’ve topped the wind-swept heights with easy grace.
lark,or even eagle flew —
And, while with
silent, lifting mind I’ve trod
untrespassedsanctity of space,
– Put out my hand, and touched the face of God.”

Mac Tip – How to Encrypt Your Mac
How to Turn On and Set Up FileVault Encryption
If you get a new Mac for Christmas and plan to make shady deals in the Ukraine and China you definitely need to do this. But everyone else should do it too.
FileVault is part of the macOS operating system and it encrypts your Mac system disk so that it can’t be accessed without the proper credentials. If I have physical possession of a Mac I can quickly break into it. If your disk is encrypted with FileVault I am stopped cold. It is that simple.
YOU SIMPLY CAN’T FORGET YOUR PASSWORDS!
FileVault 2 is available in OS X Lion or later. When FileVault is turned on, your Mac always requires that you log in with your account password.
- Choose Apple menu () > System Preferences, then click Security & Privacy.
- Click the FileVault tab.
- Click , then enter an administrator name and password.
- Click Turn On FileVault.

What I Am Working on Today
Today I am working with the LiDAR sensor on the new iPhone 12 Pro.
What is LiDAR? Light Detection and Ranging (LiDAR) measures distance using reflected light, usually from a laser measuring the time of flight of the light pulse.
The iPhone 12 Pro and 2020 iPad Pro have a new LiDAR scanner that adds depth scanning for better images. Other mobile devices use LiDAR technology to measure distances of a few feet the LiDAR sensor on the iPhone and iPad works with much higher precision at a distance of up to five meters.
Why do I care? I want to use the sensor to make highly detailed 3D models of objects and spaces for use in iOS apps and websites.
This is my first attempt at scanning a 3D model of my house using an app called simply enough 3dScanner App. It is UGLY but has potential.
