@@levyroth Turing-complete in that, any turing machine X could be simulated, as long as we give the computer access to some M_X of memory, and t_X time. As long as you can expand the memory of the system somehow, it works well enough. Basically, instead of physical machine, when speaking of turing completeness or not, you tend to talk about hypothetical version of that machine that has Just Big Enough hard drive attached. It's a bit wacky but afaik it's still "here be dragons" type deal with memory-limited computation limits. You have busy beaver function and... Uh, that's it?

[@DoctorPlasmaMC]

One of the things you didn't have time to explain is why -5, then +3. By starting with 1, one subtraction of 5 rolls over to 252. the second slot is incremented to 3. There's a lot of modulus arithmetic going on here. After 50 more loops (51 total) your values are 2 and 153. then subtracting 5 again rolls over again to 253 (and 156 now) another 51 loops and you're to 254. another 51 loops and you're to 255. another 51 loops and you're to 0 and end. At this point the second +3 slot will have added a total of 615, rolling over after 255 each time, so the desired output is reached, 103. What I haven't yet solved is how this "start 1, minus 5, plus 3" mod 256 algorithm to produce 103 was designed. There has to be a simple approach to say "I wish for this number" and pick 1,5,3 with a calculator.

You should do one using the pikachu language! It just uses a few words that are things that pikachu says, like "pika" There's a mission statement about it being made based on pikachu language instead of human language, to make coding more accessible to pikachus, which are an underrepresented minority in the industry 😅 So a few years ago I made a simple program with it to add 2 inputted numbers together... and found out that the online interpreter for it was treating the input as strings, and just concatenating 1+1 to get 11... but iirc multiplication worked 🤦‍♂️ so basically the only place I found to run it was a flawed implementation that didn't follow the official pika syntax /standard 😫

You're going in the wrong direction. BF was invented to have as few commands as possible, and to be as hard to use as possible at the same time, while being theorically capable of doing anything. Hint: there is another version of BF with as few as 6 commands, because two of the 8 main BF commands can in fact be obtained with the 6 others. That's the way!

You can also do modular arithmetic to solve this. If k is the number of times the body of the loop runs, then 1 - 5 k = 0 mod 256. Plugging this into WolframAlpha or solving by hand, you get k = 205 mod 256, so the loop runs 205 times.

[@exedeath]

The simplest one is unary, its basically this one, but first symbol is converted to 0, the second is now 1, the third is 2 and this goes on. After you have all those numbers in order, you add a 1 before the first number and convert this huge number to unary ( basically 3 is 111, 5 is 11111, 2 is 11 and this goes on). This one has just one symbol. There is also a golfcode one (forgot the name), instead of converting to unary you dont, and there are an extreme amount of golf code langueges, one called language 1, other called language 2, and this goes on and one. if the language you are compiling is "language 12345", by compiling a empty file from this language it will compile the program with the code 12345, if the code is not empty, it will compile brainfuck.

[@chillinduck7007]

I have no idea what i just watched but i like it

[@bruhgamer317]

great way to get into making compilers and interpreters, even as a total novice you can get something working in a single day

[@sebastiangudino9377]

I remember seeing a pretty fun implementation using only c macros

[@ozenthelewdable5427]

From making compilers to becoming an actual brainfuckery physicist.

[@-Burb]

Yeah I was able to create a brainfuck interpreter in literally 20 minutes. I thought it would be a fun little challenge to work on for a few hours but didnt realize just how easy it would be.

[@RexVelde]

Love this kind of vids! Esoteric languages are always fun, so I would love to see more videos covering them.

[@tamaskovacs-ajtai7489]

I didn't know what I wanted for christmas. You just gave me a perfect surprise. Always interested how this works, but never took the time and focus to do it myself. Thank you very much!

[@thegreatbambino3358]

I had a school project where I had to output all the lyrics of 99 bottles of beer on the wall using brainf*ck and then give a presentation on the language. It was actually quite fun to talk about making functions that generated the brainf*ck code for me in I think perl.

[@toastsandwich8553]

this seems so simple yet complicated the name is accurate.

[@ivanc.6064]

The "i wonder what this code does" code snippet at the end looks like my next tribal tattoo

[@buddhavskungfu]

That actually seems like a legit idea.

[@JoshingYouu]

So happy you made a video on this. It’s been one of my favorite languages for but now and is what got me into esoteric languages in the first place.

[@nikplaysgames4734]

This programming language was recreated in Geometry Dash! I beat the level, it was actually a really fun puzzle level (basically the level was that he recreated brainfugd, as well as a compiler for it and a way to put in inputs and outputs. So essentially recreated everything. Then the level teaches the user how to use the language, and makes the user solve certain puzzles with the language (for example - outputting the word "hello," which there are many solutions to)

[@auvidas3803]

thnks for the brainfk lesson!

[@1.Y.6]

Loving your videos man, keep up the good work!

[@apteryx]

I'm guessing the code at the end is something like "never gonna give you up"

[@arandomuser1723]

no it is "what a free t-shirt? be the first person to comment "my encephalon hurts!" "

[@matsbjnnes366]

I’m just now realising the calculator I wrote in COW used a strangely similar syntax. I suppose COW is just BF with the +- and operators swapped out for variations of Moo.

Things like this make me appreciate how much abstraction and normal understandable code helps our tiny little human brains

[@TheComedyGeek]

Thanks for this! I've always wanted to know more about this esoteric bit of programming trivia.

[@jaysonbunnell8097]

Y’know what though, this is way more interesting than I thought. I may try writing in brainf**k sometime edit: wrote a brainf**k interpreter in JS (still working on the input to be portable). Super fun challenge. 10/10!

[@Dr.Schnizzle]

Great! Now write a JS interpreter in brainf**k ;P

[@64TNT]

My brain is starting to literally hurt after watching this

[@toothpeak5430]

the fact that I no absolutely nothing about computers and I can slightly understand how to make a sentence with this surprises me.

[@armeli]

Creating an interpreter for bf in any language you start learning is a fun beginner project. I had no prior experience with coding when I took a beginner class in C#. After a few lessons when we had covered how loops work I made myself an bf interpreter. The most complicated thing is how to handle the [ and ] signs correctly, but it doesn't require much knowledge in coding and it's more like a logic puzzle.

[@iyviish]

Fireship is one of the very few channels i follow to learn computers. It is very unique and fun too. Keep going and do great things ❤️

I love those 2-minute videos that explain something so simply that I can think "Oh, yeah, I totally got this. Easy as hell." as long as I don't have to actually do the thing...

[@benc589]

This world is rapidly passing away and I hope that you repent and take time to change before all out disaster occurs! Belief in messiah alone is not enough to grant you salvation - Matthew 7:21-23, John 3:3, John 3:36 (ESV is the best translation for John 3:36) if you believed in Messiah you would be following His commands as best as you could. If you are not a follower of Messiah I would highly recommend becoming one. Call on the name of Jesus and pray for Him to intervene in your life - Revelation 3:20. Contemplate how the Roman Empire fulfilled the role of the beast from the sea in Revelation 13. Revelation 17 confirms that it is in fact Rome. From this we can conclude that A) Jesus is the Son of God and can predict the future or make it happen, B) The world leaders/nations/governments etc have been conspiring together for the last 3000+ years going back to Babylon and before, C) History as we know it is fake. You don't really need to speculate once you start a relationship with God. Can't get a response from God? Fasting can help increase your perception and prayer can help initiate events. God will ignore you if your prayer does not align with His purpose (James 4:3) or if you are approaching Him when "unclean" (Isaiah 1:15, Isaiah 59:2, Micah 3:4). Stop eating food sacrificed to idols (McDonald's, Wendy's etc) stop glorifying yourself on social media or making other images of yourself (Second Commandment), stop gossiping about other people, stop watching obscene content etc. Have a blessed day!
