"Demystifies binaries and bit shifting operations. I've been coding for years but each time I needed to use bit shifting I had to find some reference online or just go through trials and errors until I got the desired results. Thanks to this short course, however I'm way more confident that I can do binary calculations and bit shifting operations in my head and as a bonus I see more clearly how it can benefit me in some use cases that I didn't consider before!"

"I wish I discovered these courses 20 years back !!! Clarity is the thing with Gustavo's teaching methods. It is the most worthy hour spent (only once in life) on understanding Bitshifting operation and to be remembered throughout a lifetime.. without the need to refresh on the topic again in the future.. Highly recommended courses!!"

"Excellent! I only expected to learn how bit shifting works but in addition to that I learned about compilers, programming languages, assembly code, processors, video game history and some nice math tricks. This guy is simply on another level!"

"A quicky. A nice refresher, or introduction into bitshifting. They supply some examples where it is (was) used, and they conclude with an honest opinion about when to use it."

"Great course.

Finally took the time to understand bitshift operations (clear and concise), and the explanation uusing base10 at the beginning is a huge help"

"Funny: Good and funny explanation, I learned what is mean bitshifting and the important thing there is no need to use it in this time :-)."

"Interesting introduction to old-school programming. This was a very useful introduction to old school style programming and an informative breakdown of what exactly Bitshifting is and when and where it is appropriate to use it. Highly recommended!"

"Excellent. It says a lot about GP's teaching style that although I knew all this stuff already I *still* enjoyed this course, kind of like hanging out with a cool nerd friend and talking about how elegant bit operations are. Would love to see a follow-up course that goes into more detail, maybe "Hacker's Delight" style bit hacks"

Kory Rice
"Awesome! Thank you! This course was fantastic! The only feedback I could give is maybe mention that 2^0 = 1. Someone that doesn't know math that well might get confused on why if the right most bit = 1 the value would be 1 and not 0, which would throw off their total number when adding up each bit value. One of those things that many would just know automatically, but if someone without that knowledge was trying to follow along it could confuse them. Thank you again for this course, loved it!"
