Searching for Files

###Find images in a directory that don't have a DateTimeOriginal###

exiftool -filename -filemodifydate -createdate -r -if '(not $datetimeoriginal) and $filetype eq "JPEG"' .

###Output photos that don't have datetimeoriginal to a CSV### Note this can take a long time if you have a lot of jpgs

I see this code used in so many README files and I always scratch my head...

mkdir myAppName
cd myAppName

This is perhaps the simplest possible function you can write in bash, and should be a built-in function:

brock

try {
  jQuery.cookie = function(e, t, n) {
    if (arguments.length > 1 && String(t) !== "[object Object]") {
      n = jQuery.extend({}, n);
      if (t === null || t === undefined)
        n.expires = -1;
      if (typeof n.expires == "number") {
        var r = n.expires, i = n.expires = new Date;
        i.setDate(i.getDate() + r)
      }

The Button

Data analysis on how long until the button runs out.

Reddit unleashed the button this week and it has quickly become my all-time favorite April Fools campaign. The rules are simple, click the button (or don't) so long as your reddit account was created before April 1, 2015. Smart, they've effectively limited their pool of potential users, and guaranteed that this experiment won't go on forever. Clicking the button resets a 60 second timer.

Since this was started, the timer hasn't ever gotten below 30 seconds, to my knowledge.

Let's look at what might have been:
