jQuery/Javascript Promise

JavaScript programming runs things in order as it reads the code, but it doesn't stop to wait for the previous operation to complete before moving on.   This improves performance, but there are times where you need a bit of code to complete before you run another function.    The solution to that is called a "promise".  Basically as the code is read it will see that one particular piece of code (function) promise's to wait till another piece is done.

I use jQuery when I code, and the method I found that works best for myself is to use $.when().then(); statement.

Below is a quick example of how I format the $.when().then(); statement.

var promiseFunction = function(){ console.log("run this first") }; 
//You can include this inside the "when" brackets, but I found it cleaner to keep it separated.  This will run right away.
$.when( promiseFunction ).then(function(){  console.log("run after")  }); //The "then(function(){})" will wait till the promiseFunction is complete before running.
console.log("this will not wait for promiseFunction to complete and will run right away");
//The rest of the code will continue to run at the same time as "var promiseFunction"

Software

Hardware

  • Webcams
    • Any webcam should work, I tend to go with Logitech.
    • I like using ones that are for 780p instead of 1080p.  They both have a similar quality image, but 780p has a narrower field of view, so they tend to pick up less of the background, and allow a more focused headshot. 
    • Ipevo Webcam
  • Video Camera's
    • Under $200 cameras are often not worth the money.  Watch out for fake Amazon.com reviews on them.
    • Look for an external mic input
    • Don't buy the amazon.com package deals.  
    • FHU owns the Canon G40
    • Cellphones are probably one of the best video camera's you will find
    • DSLR for video
      • Many professional video bloggers now use DSLR cameras for video blogging.
      • Advantage
        • Nice high-resolution video's
        • Able to blur the background
      • Disadvantage
        • Limited to 30 minutes of continuous video.  All DSLR's will have this limitation because if they recorded longer they would be classified as a video recorder and subject to higher shipping fees. 
    • Audio
      • People are less forgiving of bad audio than they are of bad video.
      • Headset: Logitech USB H390
      • Microphone: Audio-Technica ATR2100
      • External video camera mic: Rode VideoMic Pro 
        • Careful with less expensive Rode mics or any external mic without a built-in power source. These tend to use the camera for power, and will only work with specific models of video cameras.
      • Wireless Mic: Rode RodeLink
      • Conference Mic: Jabra Speak

    The very fun Augmented reality (VR): Merge Cube

    This is a very fun, augmented reality toy/tool that allows you to manipulate an object as if it was in your hand.   It works with your phone or VR headsets.  The best part is that it only costs $5 on Amazon

    So my work just got a new video camera and I really wanted to find a project to play with.  We also have a large painted greenscreen wall.    This was my quick introduction into greenscreen, and the things that you can do.
