In the 1979 Sparks newsletter vol. 5 number 4 there was a poor photocopy of this photo. Ron and Russell's faces could hardly be made out... so tantalizing. (see below) Thankfully their kind mother attached a note of the source magazine, Rocky (Nr 27, 28th June 1979), and I got a copy! :D

Here's the interview that came with it:

I've been thinking about if, instead of morphing to affect/control sparks with his voice, if Tarn's outlier ability had stayed touch based but grew more and more dangerous over time :)

Okay so let’s say you have a basement just full of different computers. Absolute hodgepodge. Ranging in make and model from a 2005 dell laptop with a landline phone plug to a 2025 apple with exactly one usbc, to an IBM.

And you want to use this absolute clusterfuck to, I don’t know, store/run a sentient AI! How do you link this mess together (and plug it into a power source) in a way that WONT explode? Be as outlandish and technical as possible.

Oh.

Oh you want to take Caine home with you, don't you! You want to make the shittiest most fucked up home made server setup by fucking daisy chaining PCs together until you have enough processing power to do something. You want to try running Caine in your basement, absolutely no care for the power draw that this man demands.

Holy shit, what have you done? really long post under cut.

Slight disclaimer: I never actually work with this kind of computing, so none of this should be taken as actual, usable advice. That being said, I will cite sources as I go along for easy further research.

First of all, the idea of just stacking computers together HAS BEEN DONE BEFORE!!! This is known as a computer cluster! Sometimes, this is referred to as a supercomputer. (technically the term supercomputer is outdated but I won't go into that)

Did you know that the US government got the idea to wire 1,760 PS3s together in order to make a supercomputer? It was called the Condor Cluster! (tragically it kinda sucked but watch the video for that story)

Now, making an at home computer cluster is pretty rare as it's not like computing power scaled by adding another computer. It takes time for the machines to communicate in between each other, so trying to run something like a videogame on multiple PCs doesn't work. But, lets say that we have a massive amount of data that was collected from some research study that needs to be processed. A cluster can divide that computing among the multiple PCs for comparatively faster computing times. And yes! People have been using this to run/train their own AI so hypothetically Caine can run on a setup like this.

Lets talk about the external hardware needed first. There are basically only two things that we need to worry about. Power (like ya pointed out) and Communication.

Power supply is actually easier than you think! Most PCs have an internal power supply, so all you would need to do is stick the plug into the wall! Or, that is if we weren't stacking an unknowable amount of computers together. I have a friend that had the great idea to try and run a whole ass server rack in the dormitory at my college and yeah, he popped a fuse so now everyone in that section of the building doesn't have power. But that's a good thing, if you try to plug in too many computers on the same circuit, nothing should light on fire because the fuse breaks the circuit (yay for safety!). But how did my friend manage without his server running in his closet? Turns out there was a plug underneath his bed that was on it's own circuit with a higher limit (I'm not going to explain how that works, this is long enough already).

So! To do this at home, start by plugging everything into an extension cord, plug that into a wall outlet and see if the lights go out. I'm serious, blowing a fuse won't break anything. If the fuse doesn't break, yay it works! Move onto next step. If not, then take every other device off that circuit. Try again. If it still doesn't work, then it's time to get weird.

Some houses do have higher duty plugs (again, not going to explain how your house electricity works here) so you could try that next. But remember that each computer has their own plug, so why try to fit everything into one outlet? Wire this bad boy across multiple circuits to distribute the load! This can be a bit of a pain though, as typically the outlets for the each circuits aren't close to each other. An electrician can come in and break up which outlet goes to which fuse, or just get some long extension cords. Now, this next option I'm only saying this as you said wild and outlandish, and that's WIRING DIRECTLY INTO THE POWER GRID. If you do that, the computers can now draw enough power to light themselves on fire, but it is no longer possible to pop a fuse because the fuse is gone. (Please do not do this in real life, this can kill you in many horrible ways)

Communication (as in between the PCs) is where things start getting complex. As in, all of those nasty pictures of wires pouring out of server racks are usually communication cables. The essential piece of hardware that all of these computers are wired into is the switch box. It is the device that handles communication between the individual computers. Software decided which computer in the cluster gets what task. This is known as the Dynamic Resource Manager, sometimes called the scheduler (may run on one of the devises in the cluster but can have it's own dedicated machine). Once the software has scheduled the task, the switch box handles the actual act of getting the data to each machine. That's why speed and capacity are so important with switch boxes, they are the bottleneck for a system like this.

Uhh, connecting this all IBM server rack? That's not needed in this theoretical setup. Choose one computer to act as the 'head node' to act as the user access point and you're set. (sorry I'm not exactly sure what you mean by connect everything to an IBM)

To picture what all of this put together would look like, here’s a great if distressingly shaky video of an actual computer cluster! Power cables aren't shown but they are there.

But what about cable management? Well, things shouldn't get too bad given that fixing disordered cables can be as easy as scheduling the maintenance and ordering some cables. Some servers can't go down, so bad management piles up until either it has to go down or another server is brought in to take the load until the original server can be fixed. Ideally, the separate computers should be wired together, labeled, then neatly run into a switch box.

Now, depending on the level of knowledge, the next question would be "what about the firewall". A firewall is not necessary in a setup like this. If no connections are being made out of network, if the machine is even connected to a network, then there is no reason to monitor or block who is connecting to the machine.

That's all of the info about hardware around the computers, let's talk about the computers themselves!

I'm assuming that these things are a little fucked. First things first would be testing all machines to make sure that they still function! General housekeeping like blasting all of the dust off the motherboard and cleaning out those ports. Also, putting new thermal paste on the CPU. Refresh your thermal paste people.

The hardware of the PCs themselves can and maybe should get upgraded. Most PCs (more PCs than you think) have the ability to be upgraded! I'm talking extra slots for RAM and an extra SADA cable for memory. Also, some PCs still have a DVD slot. You can just take that out and put a hard drive in there! Now upgrades aren't essential but extra memory is always recommended. Redundancy is your friend.

Once the hardware is set, factory reset the computer and... Ok, now I'm at the part where my inexperience really shows. Computer clusters are almost always done with the exact same make and model of computer because essentially, this is taking several computers and treating them as one. When mixing hardware, things can get fucked. There is a version of linux specifically for mixing hardware or operating systems, OSCAR, so it is possible. Would it be a massive headache to do in real life and would it behave in unpredictable ways? Without a doubt. But, it could work, so I will leave it at that. (but maybe ditch the Mac, apple doesn't like to play nice with anything)

Extra things to consider. Noise level, cooling, and humidity! Each of these machines have fans! If it's in a basement, then it's probably going to be humid. Server rooms are climate controlled for a reason. It would be a good idea to stick an AC unit and a dehumidifier in there to maintain that sweat spot in temperature.

QUESTION TWO:

SWITCH BOXES. you said that’s what monitors the connections between systems in the computer cluster, right? I assume it has software of its own but we don’t need to get into that, anyway, I am so curious about this— in really really large buildings full of servers, (like multiplayer game hosting servers, Google basically) how big would that switch box have to be? Do they even need one? Would taking out the switch box on a large system like that just completely crash it all?? While I’m on that note, when it’s really large professional server systems like that, how do THEY connect everything to power sources? Do they string it all together like fairy lights with one big cable, or??? …..the voices……..THE VOICES GRR

I’m acending (autism)

ALRIGHT! I'm starting with this one because the first question that should be answered is what the hell is a server rack?

Once again, long post under cut.

So! The first thing I should get out of the way is what is the difference between a computer and a server. Which, is like asking the difference between a gaming console and a computer. Or better yet, the difference between a gaming computer and a regular everyday PC. Which is... that they are pretty much the same thing! But if you game on a gaming computer, you'll get much better performance than on a standard PC. This is (mostly) because a gaming computer has a whole separate processor dedicated to processing graphics (GPU). A server is different from a PC in the same way, it's just a computer that is specifically built to handle the loads of running an online service. That's why you can run a server off a random PC in your closet, the core components are the same! (So good news about your other question. Short answer, yes! It would be possible to connect the hodgepodge of computers to the sexy server racks upstairs, but I'll get more into that in the next long post)

But if you want to cater to hundreds or thousands of customers, you need the professional stuff. So let's break down what's (most commonly) in a rack setup, starting with the individual units (sometimes referred to just as 'U').

Short version of someone setting one up!

18 fucking hard drives. 2 CPUs. How many sticks of ram???

Holy shit, that's a lot. Now depending on your priorities, the next question is, can we play video games on it? Not directly! This thing doesn't have a GPU so using it to render a video game works, but you won't have sparkly graphics with high frame rate. I'll put some video links at the bottom that goes more into the anatomy of the individual units themselves.

I pulled this screenshot from this video rewiring a server rack! As you can see, there are two switch boxes in this server rack! Each rack gets their own switch box to manage which unit in the rack gets what. So it's not like everything is connected to one massive switch box. You can add more capacity by making it bigger or you can just add another one! And if you take it out then shit is fucked. Communication has been broken, 404 website not found (<- not actually sure if this error will show).

So how do servers talk to one another? Again, I'll get more into that in my next essay response to your questions. But basically, they can talk over the internet the same way that your machine does (each server has their own address known as an IP and routers shoot you at one).

POWER SUPPLY FOR A SERVER RACK (finally back to shit I've learned in class) YOU ARE ASKING IF THEY ARE WIRED TOGETHER IN SERIES OR PARALLEL! The answer is parallel. Look back up at the image above, I've called out the power cables. In fact, watch the video of that guy wiring that rack back together very fast. Everything on the right is power. How are they able to plug everything together like that? Oh god I know too much about this topic do not talk to me about transformers (<- both the electrical type and the giant robots). BASICALLY, in a data center (place with WAY to many servers) the building is literally built with that kind of draw in mind (oh god the power demands of computing, I will write a long essay about that in your other question). Worrying about popping a fuse is only really a thing when plugging in a server into a plug in your house.
