Processing Photos: Phone -> Library

Each time I pull photos from my phone (or camera memory card), I go through a process to pull, transform and store photos, followed by sorting, deleting and importing photos into old Google Picasa 3.9. The last version was released in Oct 2015. With 81,000 photos in Picasa, I fear the day I can no longer find a machine that I can run Picasa on.

Slowly I have been thinking about how I will sort my pictures and store them online. I don't really desire to store all in Google Photos, but it maybe the best free option. Right now, Google Photos doesn't have the options built out that Picasa does.

For example:

• Selecting an area and tagging a face manually is possible in Picasa, not in photos.
• Editing a location on a map is only possible in Picasa. You can use exiftool, to manually add GPS coords.

JSON: JavaScript Object Notation

• JSON.stringify and JSON.parse

let string = JSON.stringify({squirrel: false,
                             events: ["weekend"]});
console.log(string);
// → {"squirrel":false,"events":["weekend"]}
console.log(JSON.parse(string).events);

MATH FUNCTION

• Math.max (maximum)
• Math.min (minimum)
• Math.sqrt (square root)
• Math.PI
• Math.random (decimal)
• Math.floor (rounds down to the nearest whole number)

console.log(Math.floor(Math.random() * 10));
// → 2

• function that computes the ϕ coefficient from such an array:

function phi(table) {
  return (table[3] * table[0] - table[2] * table[1]) /
    Math.sqrt((table[2] + table[3]) *
              (table[0] + table[1]) *
              (table[1] + table[3]) *
              (table[0] + table[2]));
}

ARRAY SEARCHING FOR OBJECTS

My original questions was: Creating and accessing array of objects in Javascript

ARRAYS

ACCESS

• .push = adds to end
• .pop = removes from end

let sequence = [1, 2, 3];

TRANSPILING

• use a tool that converts your newer code into older code equivalent
• ES6 adds a feature called "default parameter values." Transpiling will modify/add the code to work with ES5
• Example:

// IN ES6, USE A DEFAULT VALUE
function foo(a = 2) {
	console.log( a );
}
// PRE ES6 EXPLICITLY CHECK FOR A DEFAULT VALUE AND DEFINE IT
