Amazon S3 (Simple Storage Service) - object storage service

One of the Amazon's core service offering was highly scalable S3 storage. In this video i explained about its quick overview and hands on explanation most of its features including  Security, versioning, static website hosting, accelerated transfers, event handling, tags etc.

I covered this topic as I intend to do more videos in future that integrate with such services of cloud computing. Let me know your feedback.

Talend Project - Child jobs, Functions and Variables

This concluding part of Talend project video explores creating sub/child jobs, how to pass data between the two and different strategies to share the data.

Code in subroutines

// Code from https://www.youtube.com/watch?v=a7-HUU4js9E

package routines;

public class formatEmails {

    public static String formatEmail(char oldRating, char newRating, String typeOfRating) {

       String fEmailText="";

    if (newRating>oldRating) {

    fEmailText=fEmailText+""+typeOfRating +" rating reduced from " +Character.toString(oldRating) +" to "+Character.toString(newRating)  +"
" ;

        }

    if (newRating

    fEmailText=fEmailText+""+typeOfRating +" rating improved from " +Character.toString(oldRating) +" to "+Character.toString(newRating)  +"
" ;

        }

    return fEmailText;

    }

}

It also explores subroutines/functions that helps you reduce the code and modularizes it.

Youtube is scanning your videos

Yesterday I uploaded a video on Youtube that I created with photos and used some background music that i downloaded from net. In an hour, Youtube sent the following email to me.

Dear sanjaykattimani,

So whats Google/Youtube up to?
Youtube is scanning all the videos that you are getting uploaded and scanning for music that matches their video/audio library. In case it matches, sends out the above warning message. This is a smart way to reduce/fight copyright infringements.
May be this was part of Googles privacy policy changes. I didn't read them. Did you?

I feel this is the best for copyright owners as they are suppose to get their share. At the same time if they start going after users like us to collect royalty, we would rather drop those songs and use some general public licensed music. Or better, I may end up creating my own music?? :)


Update 1/22/2017 - Noticed that YouTube still lets you continue to upload your videos, It certainly does not let you monetize (Earn on the ads) your videos. Its not hard to find royalty free music for most of your compositions though.
