The alpha move would be to make a short “Binary in 100 seconds” and just talk as much about it as possible in 4 seconds.

Going from transistors and building all the logic gates, then registers and arithmetic–logic units to end up with a CPU was the most fun course I had in school :D

Actually knowing how to count in binary is not only to impress your friends, it gives you a good understanding of logical operators such as OR/AND/XOR/SHIFT which are critical in some APIs and some performance sensitive programs.

You make awesome content that is rare on all over the youtube, KEEP IT UP!

I enjoyed all of the 01100100 seconds of this video. Great job!

I would LOVE to see something like 'From NAND to Tetris in 100 seconds', explaining the basics of the computer architecture and logic in 100 seconds (although I know it's a complicated topic that takes way more than 100 seconds :)

Hi, in fact Morse code have 3 possible values: dot, dash and blank
The blank is useful because you need to separate each letter from one another.
On top of that, the time between two letters is not the same as the time between two words :)

if you're not following Fireship - you're missing out.
Great content as always!

Was waiting for this, 2 weeks no video. @fireship happy new year.

My university: teaches binary for a whole semester
Fireship: Binary in 100 seconds

Actually, at 0:27 - the Morse code is a ternary language, rather than a binary one, because the letters are composed of dots (short beeps), lines (long beeps) and spaces (no beeps). Without the spaces you would not be able to tell if it is a short or a long line (beep), because it will pretty much be a continuous line (beep) for the entire length of the message.

Great video, as allays. Keep 'em coming!

i need more low-level things like this. thank you, Jeff!!!

I learned this working last year in IT. It's always refreshing to hear about it again, though. Especially from Fireship.

1:00, binary operations are very useful. You can pack several variables inside 1. For instance, if you have variables that will never pass the value of 31, you can pack 3 of them inside a 16-bits variable.
The fastest memory on computer has only 32-64k bytes. If you pack enough variables, your project will be faster. Last time I made that, my project got an instant performance boost of 5-7x times faster!
