"The problem with programmers is that, given the opportunity, they will start programming"
It's absolutely true. Every time I find a game that has some kind of modding support... I just can't help it
Spent my 1 week vacation working on a PR translating a 2015 JS lib into modern TS and then deleted it today.
@@zyriab5797At least you took care of it while you had it. 😢 =]
@@zyriab5797stop deleting stuff :(
Just not too much opportunity. if you give them too much they're not gonna do it. Now I have 12 h to build a website and set up a server to run it. wish me luck.

Company: We can't hire you because you are too young.

@@StellarRootsGames also as a young programmer, i think we all need to remember to stay humble and be aware of the scope of our knowledge. this isnt targeted towards you of course, but in meeting with a lot of other young programmers, ego is rampant and creates a really toxic cycle of competition that is centered around age. you ofc have alternative motives since youre like advertising the game (congrats btw) but i think its really important to remember to be humble and lets be the ones to fight against the stressful precedent nowadays :D
also it totally looks like im just dogging on you but i have just had this stuff on my mind for a long time and this video/comment reminded me of it
@@StellarRootsGames I mean, the age might not a factor in your case. Maybe your game is just bad
@@declspeclyup, and take a look at guys like John Carmack. He wrote some of the first ever 3D graphical video games and he’s the most humble dude ever
@@declspeclI am old and I'm a piece of s*it. I don't understand how ThePrimeagen manages to push "thousands" of lines of code every day. Specially when it comes to Rust. I'm basically dying writing low level bit-wise computations right now.
@@rumplstiltztinkerstein i feel ya, youre not alone :D
He made a CPU in Terraria AND touched grass, that's some serious dedication
did you notice he only touched grass in the beginning... if i know anything about this world, if not for a video, thats the last time he will ;)
still mad respect for the dedication and knowledge of low level stuff at such a young age
Why do you watch content which directly steals from smaller creators that only benefits the reactor. Why do you support this?
Not only did he make a pc inside terraria, but when he realized it wasn't possible, he made a mod for the game to make it possible, absolute mad lad
That kid has a bright future. Mad respect!
And it's always a pleasure seeing Terraria get some attention.
Well said! I wholeheartedly agree.
I hope he gets laid soon...

The Law that follows is, "Someone will try to port Doom to it".
There is something beautiful about a project like this. It's raw, unadulterated and honest.
I've recently seen a video about how an electromechanical Jukebox from the 1970s or 80s did its logic.

@@nadie9058 Yep, his channel is a treasure trove of strange knowledge and ancient technology and I love it. A bit like a technology museum, but much livelier.
Back in 2002 in high school, we played Mario and even DOOM on our TI-83 calculators. So, anything is possible.
Someone is going to use his mod to run Bad Apple on Terraria. Just a matter of time.
It's in the repo already
my whole interest in electronics and computers is rooted in a previous obsession with witchcraft and aliens. So yeah, its magic.
Similar with me!
Programming is basically creating magic incantations to bend the spirits inside the machine to ones undying will.
I highly recommend the SICP Book or Lecture by Hal Abelson and Gerald Jay Sussman.

I thought this kid was genius when seeing the difference between his POC and the properly implemented computer. But when he started to explain his mod and what it does, and the many languages he used to implement all the componenets, I had no more words to describe that dude.
You dont need to be a genius to do this, its about passion. You just need to have a lot of time and put in the hours. A computer conceptually really is a simple machine that basically moves data around and does some really basic math on that data, sum, rest, div, mul etc

@@jordixboy Yes but at his age the way he is able to stay focused and get shit done this quickly is still impressive. He is definitely a rare exception.
@@jordixboy Same thing. You don't get to be a genius without passion. You're not born a genius.
New Interview question, explain the difference between these 2 Terraria circuits (interviewer slides 2 pictures across table)
I started thinking it was just going to be an 8-bit CPU in terraria (already impressive). I wasn't expecting a fully complaint RISC-V CPU, rewritten game engine, and the ability to write programs for it in Rust.
The storytelling abilities of this damn kid too, geez, absolutely amazing
Me in circa 2007: I just made an adder using Digital Works Circuits for my Internal Systems course assignment, so the obvious next step is to just call it a day and work on my C++ assignment tomorrow...
That guy: I just made adders and multipliers in a game that's not really designed to do much complex circuits, so the obvious next step is to make a complete implementation of the RISC-V ISA.
I could SO relate with what you said in intro!
circa works better without conjunctions like in and but without. try it like this: ‘Me, circa 2007:blah blah blah’
@@justyahz796 Thanks.
This is the "instagram effect" times 1000x, i feel so terrible at programming now haha
I'm pretty competent, but boy I feel like I've never touched a computer in comparison
@@roccociccone597 I spent 10 years coding SOLID in high level languages, only to realize I had gotten completely detached from how computers really work and how the data is really processed. I know how you feel. It's not as hard as I thought it was though. I'd actually say that CSS is way more complex than ASM and understanding the basics of a CPU - and that was one of the big lies I used to believe: that web programming is the easiest while low level stuff is the hardest.
@@Muskar2 Oh I do work in C++ about a third of my time, the rest is Go and TypeScript. I'm just impressed by what he did :D.
@0crakhadshizzakizza0 yes, easy at first and becomes unpredictable and complex with scale and requirements. But low-level is simple and stays that way even at scale, once you have the experience to keep it that way. I also used to fall for the appeal of infinite reusability, relying on other libraries and frameworks that focus on optimizing first-to-market thinking. And I fell for the popular belief that low-level is unproductive and "unsafe" -> harder to manage. But in retrospect it's not true, and a lot of the friction comes from most of the industry riding on the quantity over quality mentality. New languages are coming out, like Odin and Jai, and many of the layers are ripe for a rewrite to make it even easier to make quality code - and I think low quality over-abstraction will eventually become much less frequent, because modern hardware advances almost don't benefit garbage-collected code anymore - and thus I think the perf gap widening will begin to matter even more - even in less competitive subindustries.
Some people are just wired differently, I do believe in hard work but you can't really deny that natural raw talent can put you on a different level.
Ok maybe I should just work at McDonalds, I clearly can't program... This kid just made me feel like a neanderthal
Oscillating crystals are tiny, pure glass discs that when attached to alternating current start to vibrate and force the frquency of the current closer towards its own natural resonance.
Its not nessecary to build an electric clock but you can add it to one to make the clock much more accurate. since its super cheap, they are always added by default.
some how... magic is still magic to me
The guy using powerpoint as an IDE was already insane to me. This got to another level.
There is actually a fast way to trouble shoot that issue. You can use gimp to do so. Create two layers make a copy of a known good section then past it over the entire map. Then you can use a filter "color erase" to find the difference in them. It will leave the different green wires showing. If you don't know what section is bad vs good. Just copy any one of them. If the one you copy is good you will only see a few or the one issue. If the section you copy is the problem section you will see a lot of locations as differences.
an actual use case for screenshot diffing. I never thought I'd see it in the wild.
people were saying debuggers are bad but imagine programming in terraria without gimp
The problem is, I imagine he had this problem many times without having a correct one to compare it to.
Brilliant.
All fine and good but wouldn't have helped him while he was building it in the first place. would only have been able to do it for certain repetitive structures. I'm sure he would have figured out a way to apply the technique but it doesnt seem like it was necessary after all. Now what I don't understand is why he didnt make a translation layer so he could use software to build the computer instead of building it by hand for 3 months. He's obviously already a genius.
the gates he's using resemble transistors, which are like switches but instead of a lever to actuate it you have an electric signal.
That's exactly what I thought when I saw it. There are many different transistor configurations that can act as logic gates.
I don't know man, i mean, Tom could do all this in like 30 minutes max, cuz he's a genius.
obviously he'd impelement JDSL in Terraria too
well yeah cuz JDSL has templating and does bi-directional result caching.
First 5 minutes all the adders are built scaled and then the next 5 minutes builds the mode to solve the wire update problem.
I absolutely love this kid. I can't wait for him to get to his first interview and show off his creations. They're going to be falling over themselves to hire him.
This player is smarter than that 17yr/o "software engineer" from a video you showed
When designing chips, debugging is usually done by having unit tests for each small module used in the bigger design. If some bug DO leak out on the actual silicone chip, well there is no way to change that unless you do some software patch.
Have you watched the 8-bit series by Ben Eater? It’s mind boggling to think about the complexity that is involved in the tools we have today.
elements of computing systems Noam Nisan for understanding the basic building blocks and how they fit together to make up the cpui
I've watched his series 2 or 3 times and I've implemented his 8-Bit CPU in Logisim and can actually run his OPCODES. Not just Ben Eater, a bit different, but javidx9 has a series with his C++ OLC Engine where he walks you through building a 6502 (NES) Emulator! Emulators are harder than making the actual CPU! Both Series are great, and to complete the Trio we have to included 3Blue1Brown! Now a few other asides for a bit of extra flavor we can add Jason Tuner's C++ Weekly for good programming practices as well as The Cherno. There's a few others, but these are the most noteworthy for good educational purposes!
This is the son of my mothers friend that I constantly was hearing about through my childhood :D
when I dropped out of uni for computer science I bought a book from amazon entitled "how to build a computer", it was a very short book which basically outlined what the kid did in the video. I read some of it, realized it wasn't really that hard and actually just a matter of following instructions, and carried on playing piano.
You must watch the video where Minecraft was made using Minecraft redstone

What is even better than this is the guy who made 16 bit CPU with only 8 basic TTL-like chips and memory... Very slow, but real CPU - many in the 80s would have been so happy for that thing as it would have been cheap to assemble home small computer in times CPUs were so expensive... This also came out lately on hackaday. I like how this guy did not just and-or gate it all, but use this stateful block too.
All of these are real cool deeds ;-)
Ben Eater? His projects are fun.
@@ontheballcity71 I think it was not Ben Eater, but some other guy. Search for "16 bit CPU 8 chips" on google. It is on youtube for "Jiri Stephanovsky" or under similar name... Ben Eater is cool too - just this literally only use 8 chips for the whole CPU!!!
this kid is absolutely cracked out of his mind
damn
and i thought i was epic for building an 8 bit adder inside minecraft
oh btw, can we get a reaction to a minecraft supercomputer next?
ive seen some of em being able to compute graphs
someone finally properly made minecraft in minecraft pretty recently, the computational redstone scene is insane
(they also have their own mod that does more or less what the mod for terraria does with wiring but for redstone)
I'm a huge Terraria fan, I'm in the beggining of my studies in javascript to code for Minecraft and I also want to learn C# in the future to create mods for Terraria. I don't know what kind of content is your channel about but I really loved your reacting (chat is hella funny too), and I'm staying. 💗
Thank you for the motivation at the end of the video!
I'm an X US Naval Nuclear Reactor operator who then majored in EE and CS. Guess i never felt inspired to build something like this in game because of the headaches of building them in real life.
I find it quit impressive that people do this stuff. I am curious why he didn't use a map editor for terraria and chose to make it all inside terraria the way he did. i would have thought the map editor would have been faster. Well maybe not if you have to keep switching back and forth to test it.
fun fact: The guy played a little bit of Terraria(8372 hours) before he started creating a computer in Terraria
The combination lock is just a bunch of and gates where one of the inputs is the previous input's output, and the the other is the switch for that and gate, then he just uses not gates to select which one needs to be on/off
10:00 Quartz is used in watches because it oscillates at a stable frequency of exactly 32,768 times each second when electricity is passed through it. You then measure the vibrations using a digital frequency counter and bobs your uncle you have a reliable clock.

Yesss. It’s all about the crystals. In watches, in computers, in everything. I remember changing the crystal in a Radio Shack Tone dialer to make a Red Box, because I never had a Captain Crunch Whistle. Phreaky days.

I do appreciate it. We're talking about components that have been engineered for decades to reach the scale of atoms.
Friggin' ATOMS.
Or just so webpages load fractions of a second faster we have globally distributed networks so the physical distance that a packet of information has to travel is kept to a minimum.
That people have been studying relentlessly to create more efficient algorithms to sort sets of data or to find a specific piece of data in a larger set and it's created a near art form, a discipline, and a now mandatory practice for future developers to get the best jobs...

Ultimately you need undying passion. No matter the circumstances.
The Gate is like a flip flop with a set and reset. Crystal oscillates at set frequency with given input voltage because of the piezo electric property
Beyond the pure technical benefit of having built something hard, he also made a clear presentation of what he had made in a way that the average person could understand
Ok I was impressed with CPU building and all that but when he hit the point where “the game engine engine couldn’t handle it so I rewrote it” I just started laughing.
I feel stupid! And I even had basic CPU design in college 😂 This little guy is simply a bloody genius! And I see him make it very very far! He’s not only got a genius mind but also sheer grit and determination.
12:30 A clock signal is just a tank circuit that produces an oscillation within a tight frequency range.
In this case, the origin of the word tank comes from a fish tank of water (filled to about halfway up the height of the glass walls) that is free to slosh around back and forth or oscillate like a pendulum. A natural oscillation circuit is a wire coil and a capacitor that is hooked up to an amplifier that keeps the water sloshing back and forth in a resonant situation. An amplifier tends to be one or more transistors. The circuit is fed back its own voltage level amplified and slightly out of phase with the oscillator tank circuit's current or voltage signal. In a capacitor, an electric field on some conductive plates are allowed to charge with positive on one plate and negative charges on the other plate. During the charging process, electron particles collect on one plate, while the opposite connection has electrons removed from it producing a positive polarity equal and opposite to the one opposite to it. A coil permits direct current flow easily but restricts higher current transitions by building a magnetic field around the coil as the current flow increases. The coil's magnetic field collapses if the current is taken away, and as the magnetic field collapses the coil's windings absorb back the established magnetic field creating a reverse current flow in the coil. A coil and capacitor can be placed into a parallel or a series configuration, but the tank circuit typically has a capacitor in parallel with a coil. The electrons within this circuit flow first one direction, then the other direction in an oscillation at a resonant frequency that is given by a physics equation.
To know how a bipolar transistor works one must first know how a diode works. A diode permits current flow in only one direction. A silicon diode is created with, what else, silicon with roughly half of p or positive material that has an almost full outer electron orbital (physics model) that can be seen by the S, P, D, F, etc, orbital shells of an atom. The chemical properties of these atoms are displayed in the periodic table of the chemical elements. The other silicon half of the diode is doped or infused with atoms that have only a single electron in their outer orbital shell--to make N or negatively polarized silicon.
When the P and N doped or infused silicon are joined together in a junction, it produces a PN junction diode. This is because a natural electric field is produced from one doped part to the opposite polarity portion.
It was discovered by experimentation that if you reinforce the electric field, then no current can flow until the field grows in size to such an extent that the field gets stronger and stronger until the force is just too great and the circuit gets a breakdown situation where the extent of the field gets larger than the PN junction boundary itself and a sudden arc of current flows through the device backward in a largely destructive way unless measures are taken to limit the current flowing through there using a series resistor of high enough resistance, but if you opposed the PN junction established electric field, then the field collapse being attempted permits only partial field collapse due to the rate of how many electrons are coming into the PN junction's field. As the field collapse that is underway reduces the field size, the diode's in-line innate resistance to current flow shall cause the junction to heat up.
In the first case, the PN junction diode is accumulating a greater field size, it is just like the charging of a capacitor.
A bipolar junction transistor inserts a third signal as a control into the junction area. It is called the base material. The typical configuration of the doped or infused silicon is either PNP or NPN with the middle letter being the base junction that typically acts as the input terminal that controls the transistor's current flow. Transistors and resisters in various configurations act as amplifiers. Some amplifiers invert the input signal while others do not. An amplifier has an innate delay due to junction capacitance that must be either charged or discharged depending on the incoming signal for the circuit.
If the bipolar junction or diode input capacitance is too high, it shall make the signal output lag its input signal more and thereby limit significantly the highest frequency range supportable by the amplifier and whatever oscillator
I took a computer organization class this summer so I'm glad I can understand most of the video
18:30 "Corporate needs you to find the differences between this picture and this picture"
Take a vibrating quartz crystal sandwiched between two metal plates. Quartz is piezoelectric meaning it turns mechanical oscillations into electrical oscillations which can be amplified. It also turns electrical oscillations into mechanical oscillations so some of the amplified signal gets fed back into the crystal to keep it vibrating.
The vibration is basically a soundwave echoing inside the crystal so the frequency is the speed of sound through quartz times the distance it travels. High frequency crystals are just thin discs with the sound wave going from side to side while low frequency crystals are shaped into tiny tuning forks.
I had no idea this was even possible in Terraria, stuff you'd dream of but never know how to do, while you have mr primeagen talking about butt chugging coffee!
This kid reminded me of how much science in computer science that I’ve forgotten over the years. I think smoke is coming out of my ears as the gears start churning again
I don't have a company, but I want to hire this kid.
"There's some serious grass going on" is now my favourite phrase xD
It's not really a gate he's built everything on. It's a transistor.
The clock can be thought of as a wiggly stick, that pushes the switch. If you push a wiggly stick, it bends and flexes - it takes a moment for your energy to reach the switch. If you run forward holding the wiggly stick, it jiggles around while you run - you are constantly putting energy into it but the output of energy is not constant.
You push energy into a quartz crystal, that energy then comes out in certain intervals. It's essentially that simple.
The clock isn't a wire that allows current to pass through, it takes energy in, 'stores' it, and releases energy at it's own frequency.
Same thing happens when you put energy in by tapping it - the energy released is in the same form as if you added electric energy.
His level of dedication is high. I remember being 16 and doing absurdly tedious things because I was "building something" and I was inspired. I wish I still had what I built or preserved it in some way. I also wish that at least one of the adults in my life gave a rats butt, regardless, I understand how this kid feels. Enjoy it while you're young.
Building a computer is not particularly difficult if you learn logic gates and the Von Neumann architecture (and have a lot of determination to see it through). What IS hard is optimising it so that you actually get performance in a simulator, building custom tooling for it and setting up automated pipelines and testing for it. That's the shit that impressed me from this. Nice.
I can't believe you reacted to this.
Saw this a few days ago and I agree. Somebody hire this kid and pay him well.
16:45 if you build stuff like this, you can quickly trace back invalid values since you can see all the lines and states...
I sometimes see genius stuff and my brain goes "I want to be like him".
In other cases i see genius things and I feel like an ant carrying bread crumbs to the nest for a reason I don't know while.
It's okay bud, every ant has its use
@@Wisdawms Thanks!
this was like going back to computer architecture class, but instead of pain, it's terraria 😂
Cat pictures are REALLY important.
it's called PLL, phased locked loop. takes the crystal's oscillating input, outputs a faster, better clock.
Passion is strong in this guy
that last speach was for prime
12:01 Humans do anything for cats. We love our masters!
Yeah those clocks aren't as complex as I thought. Basically you have some crystal that is affected by the piezoelectric effect which literally just means it vibrates when an electric current is applied. Then you have a detector of some variety detecting the vibrations and outputting a signal after counting a specific number. This only works because those crystals vibrate at very consistent intervals and frequencies.

18:48, Pixel diffing would actually work as a cool debugging tool here lol
@7:35 looks like a d-latch with pwm clock signal. basically toggling the out put with the pwm signal, basically a sort of buffer.
i love when prime casually enjoying terraria music 😂
Reminder that this is the worst his Terraria computer will be. We will see a doom clone that copies the rom into a schematic that you can copy into the game.
The gate he was describing is a transmission gate, it is commonly used to a limited extent in large MUXs for example. The problem is that it kinda degrades your signal meaning with low-voltage CPUs you can‘t have many of them in series before needing a ‚proper‘ gate to restore the voltage levels. They are very commonly used to design larger cells though and are also in things like flip-flops.
Also, I a, very tempted to get OpenROAD to work with Terraria and then be able to build what this kid did in like an hour. It would be very funny.
Anyway, kid, if you read this, come to ETH Zürich (or a university near you) and get into electronic engineering (none of that computer science business, that is for the less intelligent). You will be able to build microcontrollers and other compute structures in the real world by poking a rock just the right way, its a great time!
If you want to learn more about how processors work, Ben Eater has a great series here on RUclips where he assembles a CPU on a breadboard step-by-step.
The game "Turing Complete" is also great. You start with NOT and OR gates and end up building a turing complete processor. (You actually build two - the second being much closer to real hardware and not just the bare minimum)
I made the same comment before seeing this, just switched Turing Complete with MHRD. Totally recommend it if you haven't checked it out. With background you can probably get it done in a couple afternoons, but it's interesting in that it uses a Hardware Description Language instead of a visual assembly.
@@user-sl6gn1ss8pI think for understanding the basics, Turing Complete is better, since you are basically designing a schematic.
That said, I didn't even know about MHRD until I read your comment. I'll definitely be playing that at some point :D
@@Yotanido oh, yeah turing complete is probably the more approachable one - MHRD is basically just text and more condensed, the upside being it also introduces Hardware Description logic
the full implementation of risc v 32 bit is what im really impressed of like you could run the full linux kernel
The base of sequencial electronics is the Flip-Flop (the output is a function of input and internal state 0 or 1).
A register is a bank of flipflops. The ALU is a bank of registers wich imputs are both data and code (the instractions).
From electronics to assembler, then to C, etc. The path of old school engenieurs...
Thank a lot for watching these videos
The game Turing Complete makes can carry you for the first computer he made, but after that... I really wonder how you implement someone else's instruction set and support programming languages like this. I only really understood the basic custom assembly part and the tiny computer.
The "state" is more of his "clock". Since he is doing things by hand, it is slow. He has to accumulate all of the settings first, then release the clock in the form of what he is calling "state".
Going further since you mentioned it. The clock is just a rhythm. The crystal is used because it is consistent. At each cycle, the computer performs an operation based on the instructions supplied at that moment. In between those instances are the opportunity to set the next instructions. That's all it is. If you were adjusting the instructions as the clock is executing, everything would be chaotic and computers wouldn't be very useful because they wouldn't produce consistent and reliable results.
The malaria to cure syphillus worked because syphillus is a parasite. Inducing a high fever over a long time kills the parasite. Malaria induces a massive fever and can be managed until to clear the infection... often.
This is the first time I've seen Prime just stare, seemingly dumbfounded, at the screen.
You kind of look a little out of it though, you good man? I have had the same early adult struggles you've talked about before, so just want to make sure you good.
I'm just waiting for the 'Playing Doom in Terraria' video from now on
Awesome, admirable such dedication, 6 months
Isn't the gates he is using equivalent of latches, like for instance D-latches? (since they have state). Or perhaps that just means persistent state instead? I'm a bit rusty on the circuitry
14:55 Fun fact: the term for that "soft rhyme" is called an assonance, which weirdly enough sounds very fitting for this.
For understanding CPUs and other stuff James Sharmans 8bit pipelined cpu series is interresting
Technically it was made to do a lot of math for you, then it was improved over time, then someone wanted to make something to share your knowledge with the world, then someone decided to make something to share your thoughts with the world, and then you could add images, and now we have images of cute cats on the internet.
he should now implement his CPU on an FPGA and bring up Linux running on it
better yet - write his own flavor of Unix from scratch
