BrainFuck, a minimal esoteric programming language designed to make your brain hurt.

It's Turing -complete, but not designed to build actual software.

It's more like a work of art that challenges the status quo.

It was created in 1993 by Swiss physics student

Urban Mueller, where the goal was to create a language with the smallest possible compiler.

It was built for the Amiga 2 .0 operating system, and the compiler weighs in at under 200 bytes.

A BrainFuck program starts with a 30 ,000 byte one -dimensional array.

All values are initialized to zero, then it provides a movable pointer that you can manipulate with eight different commands.

Use angle brackets to move the pointer left or right by one cell at a time,

then increment or decrement the value in a cell using plus or minus.

Use a period to output the byte at the pointer's current location,

or use a comma to accept input and store it at the pointer's current location.

And finally, use opening and closing brackets to create a loop.

Notice how brainfuck doesn't require silly things like variables, functions, and classes.

To get started with BrainFuck, delete your operating system and install Amiga OS.

Then create a file ending in .bf, which stands for BrainFuck.

Any characters that are not the 8 I mentioned previously will be ignored as a comment.

At this point, we have an array with 30 ,000 8 -bit numbers, all set to 0.

To say hi mom, we'll need to set each number to its corresponding ASCII character.

We can increment the first cell, then enter a loop with an opening bracket.

For each iteration of the loop, we'll decrement the current cell by 5, then use an angle bracket to move one cell to the right.

We'll increment that cell by 3, then move back to the left and close the loop.

The loop will continue until the original cell goes back to 0, at which point it will exit.

We now have a value of 103 at index 1.

We can move the pointer to it, increment it to 104, then use a period to output it.

That corresponds to the letter H in ASCII.

We can increment it again to get 105, which corresponds to the letter I.

Now we continue this process of manipulating memory like cavemen until we output all the characters that we need.

Now to run your code, use right -click copy and paste it into one of the many online interpreters.

Congratulations, you just said hi to your mom in brainfuck.

Vocabulary and speaking notes for this lesson

This speaking lesson is built on the video “Brainf**k in 100 Seconds”. The speaker keeps coming back to these words: brainfuck, cell, increment, loop, bracket. This video has 33 sentences and 451 words to shadow. The speech runs for 2:09. The speaker talks fast, about 209 words per minute, so expect linked and reduced sounds. Only 77% of the words are among the 3,000 most common in English, so the vocabulary is demanding.

How to practise with this video

Listen to the whole video once without speaking and note the words you do not know.
Start at 0.75× speed, shadow it sentence by sentence, then go back to normal speed once it feels easy.
Record yourself and compare with the original, paying attention to words like loop, bracket, output.

What is the Shadowing Technique?

Shadowing is a science-backed language learning technique originally developed for professional interpreter training and popularized by polyglot Dr. Alexander Arguelles. The method is simple but powerful: you listen to native English audio and immediately repeat it out loud — like a shadow following the speaker with just a 1–2 second delay. Unlike passive listening or grammar drills, shadowing forces your brain and mouth muscles to simultaneously process and reproduce real speech patterns. Research shows it significantly improves pronunciation accuracy, intonation, rhythm, connected speech, listening comprehension, and speaking fluency — making it one of the most effective methods for IELTS Speaking preparation and real-world English communication.
