Easy way to change image from 4:3 to 16:9 using Ms. Paint while respecting existing image aspect ratio

Assumptions: Height stays the same (only the width changes) Keep original image aspect ratio and keep the image in the middle of the new size image Add black boxes on the 2 sides to respect the exiting image perspective Calculation for the new 16:9 size New width = 16 / 9 multiply by the height (note: we are trying to keep same height) E.g.: original size is 3840 x 2880 (4:3) New width = 16 / 9 * 2880 = 5120 New image size = 5120 x 2880 (16:9) Instruction using Paint to add 2 black bars on the side of the image Goal: increase image size from 3840 x 2880 to 5120 x 2880 First increase image width to 4480 (File -> Image Properties) Rotate 180 degrees <- this is the main trick :) Increase width to 5120 Use Fill tool to fill the 2 sizes with Black (or whichever color you like) Rotate 180 degrees to get back to the original format ---------------------- Just another note for my future reference :).

Windows Storage Space - cheap method for a simple software RAID 1 (2-way mirror) and cold storage backup

Just documenting for my own future reference so I don't need to re-google. Upgrade the space in Microsoft Storage Space To keep the cost down, I started with 2 drives that are of different sizes initially: 1TB and 2TB Once the Storage Space is almost full, I buy another drive that is double the size of my largest drive. In this case: 4TB. Remove the 1TB drive physically and keep it in cold storage with posted note on it. In the worst case scenario that the mirror system is gone and I lost both main drives (thief, Ms. Storage Space gone wrong, etc.), I have a smaller out-dated backup in place that I can rebuild. Note: DO NOT use the remove drive option on Windows as you will remove all data on the drive Once the storage space is full, I add another drive to the storage space that is double the size of my largest drive to change to a 2TB and 4TB pairs (can only use up to maximum of 2TB). I use this system to keep the cost down - e.g. only need to upgrade 1 drive at a time. Warning: T
