| kfx | I don't need fancy engineering for a box that sits in a corner under my desk and just does work. Plus, when I spend money on a forty-core machine with 128gb of ram, I want assurances it's been tested with rhel. Finally, I want replacement parts overnighted to me. That pretty much leaves Dell, Lenovo, and HP. | 05:33 |

| Christoph_ | I just can't wrap my head around this Volts and Amps thing | 17:00 |
| Christoph_ | If electricity was a software, you'd just have something like a battery, with a certain value of electricity inside | 17:01 |
| Christoph_ | and it would flow through the circuit at a floating point value. Say 0.475 electricity per second. Or 0.004832 per second. | 17:01 |
| Christoph_ | And that's kind of how Amps work. | 17:02 |
| Christoph_ | But they why do Volts exist? Or why do Amps exist if Volts are a thing? | 17:02 |
| Christoph_ | I know the water pipe analogy, but... why? | 17:02 |
| Christoph_ | I know there must be some little thing that I'm not seeing about all of this, does anyone have an idea what it may be? | 17:03 |
| Christoph_ | Oh, nevermind, wrong IRC channel, sorry! | 17:04 |
| minute | Christoph_: haha | 17:04 |
| minute | Christoph_: think of a water pipe and a faucet. voltage is kind of like the pressure. current is the actual amount of water flowing | 17:05 |
| Christoph_ | The thing is, I'm aware of the analogy, and understand the relationship between Voltage and Current. | 17:07 |
| minute | Christoph_: ah ok. so what you're describing, the floating point value, that is the current | 17:07 |
| Christoph_ | I guess what I don't understand is... why they both exist? | 17:08 |
| Christoph_ | Yes | 17:08 |
| minute | Christoph_: because current needs to come from somewhere and go to something | 17:08 |
| minute | Christoph_: and that is defined by the voltage... i.e. points that have higher voltage are higher up. the current can flow from them to lower voltages (and GND being 0V) | 17:09 |
| Christoph_ | I guess that, and then also, resistance is a matter of fact in the physical world | 17:10 |
| kfx | everything is out of balance and tries to even out, if there's a path that allows it | 17:10 |
| minute | Christoph_: yes, a higher voltage (pressure) source can more easily overcome resistance | 17:10 |
| minute | Christoph_: so if you have a high resistance and a low voltage, very little current can flow | 17:10 |
| minute | Christoph_: but if you have a high voltage, you can get more current across | 17:10 |
| Christoph_ | kfx: Phrasing it that way helps a lot | 17:11 |
| kfx | this is why you occasionally still hear voltage referred to as "electric potential" -- it's a description of what would flow, if it could | 17:12 |
| Christoph_ | Then I guees to wrap my head around it better, I need to learn why specifically you'd want more or less current or voltage in specific situations. | 17:12 |
| minute | yeah. a high voltage can lead to small structures getting very hot | 17:13 |
| minute | because of resistance losses (heat dissipation) | 17:13 |
| minute | so that's why you try to work with low voltages in chips | 17:14 |
| vkoskiv_ | Isn't that specifically high current, no? | 17:14 |
| minute | but to get the power to your machine, you want higher voltages, to get enough current through your cables to the devices | 17:14 |
| vkoskiv_ | High voltage = big zappy zappy but less heat | 17:14 |
| minute | vkoskiv_: well, true | 17:14 |
| minute | i guess CPUs move a lot of current at low voltages | 17:15 |
| minute | (like around 1V or even less) | 17:15 |
| vkoskiv_ | Yeah, tens of amps though. | 17:15 |
| vkoskiv_ | I don't think any single conductor inside there has multiple amps, but there are just so many individual conductors that it adds up | 17:15 |
| minute | yep | 17:15 |
| vkoskiv_ | Macs tend to have a lot of current sensors, and I remember it often showing >20A going to the CPU core | 17:16 |
| josch | And once you wrapped your head around the topic and think you understood it, watch this awesome Veritasium video https://youtu.be/bHIhgxav9LY :D | 17:17 |
| minute | ahaha | 17:17 |
| minute | josch: what's the exec summary? do they tell you that current actually flows the other way around (i.e. out of GND)? | 17:17 |
| Christoph_ | Hm, thinking of it all in terms of restrictions in the physical world makes a lot more sense to me. | 17:25 |
| Christoph_ | ...as opposed to, learning from "easy" visual abstractions. | 17:26 |
| josch | minute: that there is actually no "flow" in the sense that the energy is transmitted because electrons travel from A to B but the energy is transmitted by the EM field while electrons barely move | 17:27 |
| minute | josch: ah yeah | 17:27 |
| Christoph_ | josch: another of my back-of-the-head questions answered, thank you | 17:28 |

| Boostisbetter | Just FYI, kfx: looks like Maingear is able to ship to APO, so I'll most likely be going that route. | 17:39 |
| Boostisbetter | I built my old workstation myself, and 20 before that, but these days, I just don't have the time to sit there and get it all working. | 17:40 |
| kfx | Boostisbetter: oh, I get it. I haven't built a desktop in at least a decade | 17:43 |
| minute | Boostisbetter: i let mindfactory build my pc after selecting the components, it was just a little extra fee, incl. to make sure that the components actually work together | 17:47 |

| Boostisbetter | minute: is that a German company? Do they install Linux on it as well? | 17:50 |
| minute | yeah, german. installing linux is as easy as putting an image on a usb stick and installing it? | 17:51 |
| Boostisbetter | minute: What I mean is that they test the configuration for compatibility, etc. | 17:51 |
| minute | Boostisbetter: no, AFAIK they don't do that. | 17:52 |
| Boostisbetter | Im looking at a Maingear Apex Turbo currently | 17:52 |
| minute | i asked around before what the safest GPU bet was, for example | 17:52 |

| kfx | mine's a precision 7280, with two intel Gold 6138 CPUs and a Radeon WX 5100. after years of using nvidia cards, it's nice not to have to do anything stupid to get video working | 18:17 |
| Boostisbetter | will those compute gpus work for gaming? I don't have any work related gpu loads. | 18:40 |
| kfx | it's not a compute gpu specifically, it's just a video card that happens to support opencl | 19:03 |
| kfx | purpose-built GPGPUs don't even have video connectors on them | 19:03 |
| Boostisbetter | kfx: thanks, yeah I just ordered a maingear turbo | 19:05 |
| Boostisbetter | that should do it for now. | 19:05 |
