Why you're here

Kids Hacking is a great playground for my cyber friends to learn coding, exchange knowledge, collaborate on new ideas and the most important to enjoy and have fun during their stay on the site. Except from the material published on this site, a collection of videos can be watched at my YouTube channel and all available source code can be forked from my GitHub account. Also, you may text me in Twitter . Further, in order to clear any misunderstandings on the origins and the meaning of the term "hacker", based on Wikipedia " A computer hacker is any skilled computer expert that uses their technical knowledge to overcome a problem ".

Kids Hacking - Yamaha P-125B Digital Piano, The Sound of Silence

Hello darkness, my old friend I've come to talk with you again Because a vision softly creeping Left its seeds while I was sleeping And the vision that was planted in my brain Still remains Within the sound of silence In restless dreams I walked alone Narrow streets of cobblestone 'Neath the halo of a street lamp I turned my collar to the cold and damp When my eyes were stabbed by the flash of a neon light That split the night And touched the sound of silence And in the naked light, I saw Ten thousand people, maybe more People talking without speaking People hearing without listening People writing songs that voices never share And no one dared Disturb the sound of silence "Fools", said I, "You do not know Silence like a cancer grows Hear my words that I might teach you Take my arms that I might reach you" But my words, like silent raindrops fell And echoed In the wells of silence And the people bowed and prayed To the neon god t

ScratchJr - Falling Back to Earth, Source Code Overview

Let’s go through all the source code written for the ScratchJr program “Falling Back to Earth” as published on this  post . Download project source code from GitHub: FallingBacktoEarth.sjr

ScratchJr - Coding Hard

The gear used for the implementation of our software development projects, is a laptop, a tablet and a broadband internet connection. Other than that, select your favorite Integrated Development Environment (IDE) and you are ready to code hard.

ScratchJr - Falling Back to Earth

This is my first program in ScratchJr, aiming to understand its capabilities and provided list of functions. I was impressed by its completeness and ease of use. Everything that you may need by a basic programming language is in there... objects, variables, actions, loops, timers, triggers and messages presented as blocks help you to understand all these concepts. The only guidance that you may need by an adult, is to define the problem (project requirements) that you will have to solve (code) and your motivation will boost to maximum. ScratchJr is awesome!... I can't wait to code more projects ;)
