Okay, look, they talk to a Google rep in some of the video clips, but I give it a pass because this FREE course is a good baseline for personal internet safety that so many people just do not seem to have anymore. It's done in short video clip and article format (the videos average about a minute and a half). This is some super basic stuff like "What is PII and why you shouldn't put it on your twitter" and "what is a phishing scam?" Or "what is the difference between HTTP and HTTPS and why do you care?"

It's worrying to me how many people I meet or see online who just do not know even these absolute basic things, who are at constant risk of being scammed or hacked and losing everything. People who barely know how to turn their own computers on because corporations have made everything a proprietary app or exclusive hardware option that you must pay constant fees just to use. Especially young, somewhat isolated people who have never known a different world and don't realize they are being conditioned to be metaphorical prey animals in the digital landscape.

Anyway, this isn't the best internet safety course but it's free and easy to access. Gotta start somewhere.

Here's another short, easy, free online course about personal cyber security (GCFGlobal.org Introduction to Internet Safety)

do I think Ephy learned how to use the computer from Brain and that it was probably really great offscreen bonding time for the two of them? Indubitably

Been obsessing over the fact that my old oc, Artie, and Kinitopet are like so one in the same it's actually crazy.

Pink AI that's friendly on the surface, is actually really clingy and obsessive at times. Lonely and really just trying to fulfill a core objective as set by their creator or other influences, someone or something that they look up to as a godly figure maybe.

They both act as your friendly AI assistant, Artie is just for a specific program, while Kinito just gets to be his own thing.

Both want you to stay with them. Both will go out of their way to do things to make sure that happens.

they are so silly to me, and i love them

Also I found an old sketch from way back that somehow mimics the literal same plot beats to the ending portion of kinitopet and that threw me for a loop. Too bad it was only a concept sketch.

ohhh i love sentient silly ai so much... ohhh i love themmmmmm

something something sentience of ai is inherently a tragedy or something like that.

thank you for listening to me ramble. ahem.

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.

I'm curious, what would you folks rather use to do work and browse tumblr etc?

[squid--inc]

anybody willing to tell me if this flash drive will work for storing games of steam (have not been able to play fallout 4 on my laptop because i have such little memory on my laptop, among other games)

be kind I'm kind of tech illiterate

Okay maybe I shouldn't upload art in bulk

Love spending 30 minutes checking how to disable AI from my stupid phone so that I can do the stupid update which I have to do because my battery keeps overheating!

And then find out that this stupid phone has been sending images to Apple because the enhanced visual search has been on since the last update! Beloathes, I did not sign up for that thanks!!!

My dad is finally “entering the digital age” AKA, Using The Internet and he keeps telling me about how amazing things are and telling me to get things (like Spotify, Bluetooth headphones, streaming services) and I’m just there like

[scentofpines]

i have a course where we have to send a homework to the prof by e-mail every week and then we get a short feedback from him. last week i didn't get any feedback so i asked him briefly during this week's homework whether he got my mail. now the dude said he didn't get it and “in dubio pro reo”, i'm allowed to “miss” class twice anyway like in face-to-face seminars and maybe it's in his spam folder. and like??? there is no fucking “dubio”. the mail is in my sent-folder. it was sent. i didnt "miss” class. if you think it could be in your spam folder…then..…just check if it is?????? bro how am i supposed to make sure now that he gets my homework in the future?? just check your spam regularly like normal ppl. boy i hate incompetence
