Below there a 2 images (a black and a white one, but could be any monochrome picture) that look rather boring. But both of them contain a very, very, .. OK & very important and secret message.
Simply write a SB program to reveal and view the hidden contents.
Hint: The red component in some parts of the image(s) is NOT as it should be on a pure black (or white/monochrome) image! Maybe even try to show the solution(s) in colors (eg. red, green; blue, yellow like on a MS flag)
PS: To impede cheating there’s also included a simple ‘flood protection’. To create a similar image yourself, you would need LitDev Ext and ~ 10-20 lines of code. - by Pappa Lapub – NoSleep
Imagine you are running a huge download or another unattended process and you want to avoid that your computer gets to sleep or hibernation, while you’re away.
Write a simple SB program, that keeps your system awake in the meantime.
