ldong / rtree.js
Created October 6, 2015 00:07
Generate dependency tree for RequireJS apps
// Usage:
//
// 1. Put this in the file that gets first loaded by RequireJS
// 2. Once the page has loaded, type window.rtree.map() in the console
// This will map all dependencies in the window.rtree.tree object
// 3. To generate UML call window.rtree.toUml(). The output can be used
// here: http://yuml.me/diagram/scruffy/class/draw
requirejs.onResourceLoad = function (context, map, depMaps) {
if (!window.rtree) {
window.rtree = {};

File Magic Numbers

#File Magic Numbers

Magic numbers are the first bits of a file which uniquely identify the type of file. This makes programming easier because complicated file structures need not be searched in order to identify the file type.

For example, a jpeg file starts with ffd8 ffe0 0010 4a46 4946 0001 0101 0047 ......JFIF.....G ffd8 shows that it's a JPEG file, and ffe0 identify a JFIF type structure. There is an ascii encoding of "JFIF" which comes after a length code, but that is not necessary in order to identify the file. The first 4 bytes do that uniquely.

This gives an ongoing list of file-type magic numbers.

ldong / movedigiphotos.bash
Created December 27, 2015 17:58 — forked from jvhaarst/movedigiphotos.bash
Bash script to move images, based on exif data and file timestamp
#!/bin/bash
# Reads EXIF creation date from all .JPG files in the
# current direcotry and moves them carefully under
#
# $BASEDIR/YYYY/YYYY-MM/YYYY-MM-DD/
#
# ...where 'carefully' means that it does not overwrite
# differing files if they already exist and will not delete
# the original file if copying fails for some reason.
