Here are some great videos from Code.org Bill Gates does the intro video!






Wow, I have not posted in a long time. 😌

Quantum Computers will one day make today's computers and devices look like ancient calculators!

Here is that smiley face or not sure face that I made!

A couple of days ago, I got on Khan Academy, a learning website! And I learned "computer programming". For example:

fill(255, 218, 115);
ellipse(103, 195, 33, 50);
ellipse( 297, 193, 33, 50);
ellipse( 200, 200, 200, 200);
fill(255, 255, 255);
ellipse( 153, 176, 40, 40);
ellipse( 247, 176, 40, 40);
strokeWeight(10);
line( 242, 246, 166, 257);
fill(255, 229, 156);
triangle(204, 186, 249, 235, 160, 236);
ellipse( 198, 222, 15, 15);

ellipse( 212, 222, 15, 15);
ellipse( 250, 179, 15, 15);

ellipse(155, 179, 15, 15);
So you're probably thinking " what the heck?! That is just a bunch of letters and numbers!" Well, it's more than that!! That actually turns into a smiley face or a not sure face! Ellipse means circle! And there's the x coordinate of the center and the y coordinate of the center, the width and the height! It's really cool!

Sorting things is one of the most important algorithms used by all computers.

Here is the Bubble Sort algorithm. You just keep swapping the nearest neighbor until you can't swap things anymore. At that point the list of numbers is sorted.

9 4 2 12 23
Pass 1: swap the 4 and 9 : 4 9 2 12 23
Pass 2: swap 4 and 2: 4 2 9 12 23: 2 4 9 12 23
There is nothing left to swap, so it is sorted!
Most software uses a lot of sorting, so it is very important to learn.

The fastest way to sort things is called Merge Sort below. It is a more advanced method.

China has the fastest computer in the world.
