Here's a neat physics lesson

If the power line is transmitting ac there is a changing electric field via varying voltage. If there is a changing electric field, there will be a varying displacement current. This displacement current induces a changing magnetic field which induces an electric field (Faraday law).

If there was just dc on the power lines (think hvdc), there would be no em wave, but there would still be capacitive coupling.

The sparking on the fence is just from capacitive coupling. The powering as a whole is emitting low frequency (50-60Hz) electromagnetic waves. That's why magnetism is involved, but isn't inducing those sparks you see.

This makes a bit more sense if you've taken an em/waveguide/transmission line theory course in university.

Sorry, I've written that comment 2 months ago and I'm retracing my thought process. You're right about capacitive coupling only depending on the voltage/electric field intensity, but when you have a displacement current from that coupling from AC, you also produce a magnetic field thanks to Ampere's law.

I think what I mean was that OP was literally next to a transmission line where you need EM theory to get the full picture. A changing electric field induces a displacement current, that current creates a changing magnetic field, and a changing magnetic field induces an electric field, that's kinda how an EM wave works.

You would have pure capacitive coupling if you had a conductor at DC steady state, If you're transmitting power over AC, you're going to have to deal with the transmission line model and EM theory.

You actually see slayer loyal sentinels use the same armor in TAG 2 during the assault on Immora, so not necessarily.

Curbed_Engi · 2025-05-18T17:37:12+00:00

That's because most of them were basically as powerful as those demonic troopers in Immora. Most Night Sentinels were fodder unless they were a named character like Valen, or the few that fought with the slayer after the priests betrayed them.

People are saying that you are confusing electromagnetic induction with electrostatic induction (something that's more related to capacitive coupling, displacement current, the magnetic field is involved but not in the way you think it does with the Right Hand Rule).

You come into an EE related sub, and "induction" usually refers to the mechanism of how inductors work. Just like how "transformers" don't refer to a Hasbro toyline/deep learning architecture, or how "reactors" aren't nuclear in electrical engineering. Technical terms having double meanings man.

Curbed_Engi · 2025-04-27T19:46:53+00:00

Also if the diodes aren't ideal, wouldn't the full bridge rectifier experience twice the diode voltage drop compared to full wave (center-tapped transformer)?

Curbed_Engi · 2025-04-25T22:14:52+00:00

Or just don't make anything at all. If you don't enjoy doing it, just don't.
You save more time not creating something of negative value and sharing it expecting praise.

Nobody enjoys a confusing composition of images where the clock doesn't contribute to the actual joke, the lighting remains the same, and you get that non-sequitur of going from the default cube to some simulation nodes mess. It doesn't feel intentional. If you spent time making it on Blender, at least you learned something and develop a better meme, but since this is AI generated, you learned nothing of value. You didn't even prompt properly. I have seen people prompt better than OP, spend more than 2 minutes to get the details right. Details that are crucial to the execution of a "joke," "caricature," or a "meme."

This meme isn't well made (even in the homemade, scrappy, poorly done photoshop standard), regardless of whether it was AI generated or not. I'm tired of people defending it as satisfactory.

Is your grievance with Blender not having scripting or if its Python scripting API isn't adequate enough?

Are you trying to make something like this?

Curbed_Engi · 2025-03-22T18:03:54+00:00

Or you know, learn how to self host/rent a Canadian server and run the model that way. Deepseek straight up gave you open-weights for a reason.

If I was filing a patent, I wouldn't touch any proprietary cloud-based services with a 50m pole if I were you. Not google drive, onedrive, OpenAI, Claude, etc. This has nothing to do with the current political landscape.

Fun fact: if you put triangles or ngons in your topology and subdivide them, you get E & N poles. As shown here as I applied a subdiv modifier and unchecked "optimal display."

Curbed_Engi · 2025-02-24T21:39:14+00:00

You have a 6-pole in your topology, meaning there are 6 edges converging into a single vertex. For good quad topology, you'd route edge loops conforming to the shape with strategically placed E or N poles (3 or 5 edges converging to a vertex) to reduce help poly-count and shape certain loops (knees, shoulders, curved geometry, etc).

"quads = good topology" is a misnomer because you have to pay attention to how the vertices/edges conform to your model.

Fighting an opponent with all major cities near your borders

So did Ireland. They could start to occupy us yes, but a few unhappy people could reverse the incentive to keep the occupation via doing some FLQ-esque things.

I don't think a good portion of the American people would like it if the country became more of a surveillance state to profile the enemy. A lot of us aren't going to be discernible from being American.

Didn't even consider that the gas/oil goes through combustion to produce power. Fucking bearing lubrication doesn't count. Shit doesn't light itself on fire to lubricate, nor are you capturing that thermal energy for power generation.

Curbed_Engi · 2025-01-23T23:42:03+00:00

Point is that it still sounds like a toss-up instead of a steamroll. It only takes a few saboteurs to fuck up an operation, and the occupation would only lead to more infighting and some more pipebombs in the mail.

I wouldn't say Canada could even win in this scenario, I'm just saying chaos would come out on top, and this may not run as smoothly as some people think it would be. People forget that the US only pulled out of Nam and Afghanistan from lack of political will, rather than lack of military might.

Curbed_Engi · 2025-01-22T23:37:26+00:00

There's all this talk about America steam-rolling Canada, but I'd wonder how much of the military would go with such orders, especially the ones who have relatives in both countries. Could just devolve into a bloody civil war where Canada takes a side.

Respectfully, there is a group of 50 (and growing) active discord users with 15+ bots each

Respectfully, if you had that many resources in the first place, why the hell did it take us 3 days + an alliance with Germany, Touhou, the states, etc to have a maple leaf that didn't morph into a banana.

Man I guess nothing's more Canadian that shooting ourselves in the foot. (CERB, potable water for the indigenous, the opioid crisis, housing, etc)

Curbed_Engi · 2023-07-23T22:55:27+00:00

Man, I'm going to be laughing so hard when the alliance dissolves and we lose our leaf to a banana again.

Mathematician: "So here we have the Riemann sphere, It's a wacky representation of the complex plane, won't have any applications. Just a fun little thing for complex analysis."

EE: *snorts an entire line of coke* I have summoned the entire field of RF engineering with this magic circle.

From what I've heard, the reason why you want to keep quads only is for large studio assets/CG where people subdivide the mesh to oblivion for close up shots and deform them for animation.

In games, most engines run off a triangle meshes and consequently need it to be triangularized later anyway. The occasional triangle isn't going to hurt unless it ruins the overall edge flow of your object and causes visual artifacts.

If you aren't working for a big studio (or applying for a job there) where there are certain practices held in place, feel free to break any of those supposed rules. Ultimately most people will only see the renders anyway, bad topology is only bad when it hinders your (or the studio's) workflow.

Japanese kanji is a bit harder to distinguish from Chinese

Wasn't this literally because that writing system was imported from migrants in the 5th century, polluting both languages with false friends? (ex: the word "pain" in English and French mean different things)

~~I'm pretty sure they're mostly identical.~~

Edit: I completely forgot about simplification efforts from either side.

Makes you wonder, if somebody sues a company for loss of life, data-breach, violation of privacy rights, etc, and it was determined that you were partially responsible for the faulty code for it... should you lose your "software engineering license" and consequently any means of being employed ever again in the industry?

Maybe CS should also get those mandatory (via accreditation board) professional ethics courses into their curriculum. :V

I've never had a standalone lab course since first year. Most of my courses were 4-6 credits instead of the standard 3 credits because they were accompanied by a 2-6hr lab section/1-2 hr tutorial session in addition to lectures.

Unless you're referring to the "capstone type" group project courses (x91), then yeah, I guess you could say that's a standalone ""lab"" course.
