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.

Applied AI - Integrating AI With a Roomba

AKA. What have I been doing for the past month and a half

Everyone loves Roombas. Cats. People. Cat-people. There have been a number of Roomba hacks posted online over the years, but an often overlooked point is how very easy it is to use Roombas for cheap applied robotics projects.

Continuing on from a project done for academic purposes, today's showcase is a work in progress for a real-world application of Speech-to-text, actionable, transformer based AI models. MARVINA (Multimodal Artificial Robotics Verification Intelligence Network Application) is being applied, in this case, to this Roomba, modified with a Raspberry Pi 3B, a 1080p camera, and a combined mic and speaker system.

The hardware specifics have been a fun challenge over the past couple of months, especially relating to the construction of the 3D mounts for the camera and audio input/output system.

Roomba models are particularly well suited to tinkering - the serial connector allows the interface of external hardware - with iRobot (the provider company) having a full manual for commands that can be sent to the Roomba itself. It can even play entire songs! (Highly recommend)

Scope:

Current:

The aim of this project is to, initially, replicate the verbal command system which powers the current virtual environment based system.

This has been achieved with the custom MARVINA AI system, which is interfaced with both the Pocket Sphinx Speech-To-Text (SpeechRecognition · PyPI) and Piper-TTS Text-To-Speech (GitHub - rhasspy/piper: A fast, local neural text to speech system) AI systems. This gives the AI the ability to do one of 8 commands, give verbal output, and use a limited-training version of the emotional-empathy system.

This has mostly been achieved. Now that I know it's functional I can now justify spending money on a better microphone/speaker system so I don't have to shout at the poor thing!

The latency time for the Raspberry PI 3B for each output is a very spritely 75ms! This allows for plenty of time between the current AI input "framerate" of 500ms.

Future - Software:

Subsequent testing will imbue the Roomba with a greater sense of abstracted "emotion" - the AI having a ground set of emotional state variables which decide how it, and the interacting person, are "feeling" at any given point in time.

This, ideally, is to give the AI system a sense of motivation. The AI is essentially being given separate drives for social connection, curiosity and other emotional states. The programming will be designed to optimise for those, while the emotional model will regulate this on a seperate, biologically based, system of under and over stimulation.

In other words, a motivational system that incentivises only up to a point.

The current system does have a system implemented, but this only has very limited testing data. One of the key parts of this project's success will be to generatively create a training data set which will allow for high-quality interactions.

The future of MARVINA-R will be relating to expanding the abstracted equivalent of "Theory-of-Mind". - In other words, having MARVINA-R "imagine" a future which could exist in order to consider it's choices, and what actions it wishes to take.

This system is based, in part, upon the Dyna-lang model created by Lin et al. 2023 at UC Berkley ([2308.01399] Learning to Model the World with Language (arxiv.org)) but with a key difference - MARVINA-R will be running with two neural networks - one based on short-term memory and the second based on long-term memory. Decisions will be made based on which is most appropriate, and on how similar the current input data is to the generated world-model of each model.

Once at rest, MARVINA-R will effectively "sleep", essentially keeping the most important memories, and consolidating them into the long-term network if they lead to better outcomes.

This will allow the system to be tailored beyond its current limitations - where it can be designed to be motivated by multiple emotional "pulls" for its attention.

This does, however, also increase the number of AI outputs required per action (by a magnitude of about 10 to 100) so this will need to be carefully considered in terms of the software and hardware requirements.

Results So Far:

Here is the current prototyping setup for MARVINA-R. As of a couple of weeks ago, I was able to run the entire RaspberryPi and applied hardware setup and successfully interface with the robot with the components disconnected.

I'll upload a video of the final stage of initial testing in the near future - it's great fun!

The main issues really do come down to hardware limitations. The microphone is a cheap ~$6 thing from Amazon and requires you to shout at the poor robot to get it to do anything! The second limitation currently comes from outputting the text-to-speech, which does have a time lag from speaking to output of around 4 seconds. Not terrible, but also can be improved.

To my mind, the proof of concept has been created - this is possible. Now I can justify further time, and investment, for better parts and for more software engineering!
