#Engineering shit

[snaitf]

Engineer here. i can tell you exactly what happened.

In the early 60s, copper prices went up, so copper wiring got expensive. Everyone went "hey that's fine, cause we now know that aluminum conducts electricity just as well and is currently cheaper." So for the next decade, new houses were built with aluminum wiring.

Yeah. Turns out, aluminum wiring is a BAD idea. The wiring itself isn't bad. The problem is when you connect it to plugs designed for copper (you know. Basically every plug ever at that point). The copper-aluminum connection generates heat, because the metals are dissimilar. (This is materials science 101. Even touching copper to iron at room temperature will generate a very slight amount of electricity/ heat. All sorts of sensors are based on this principle.) Aluminum also oxidizes faster than copper, leading to bad connections which leads to higher resistance. If you're lucky, high- resistance spots like that generate heat. If you're unlucky, it generates a spark. Houses with aluminum wiring were found to be 55 TIMES more likely to have an electrical socket reach fire hazard condition due to degradation at the outlet.

So, we banned aluminum wiring in 1972. Slightly better while still being cheap was a copper-clad aluminum wire, which included a thicker outer layer to dissipate the heat.

Then. THEN. The price of copper dropped back down. In 1977. So, electricians started using all-copper wire again.

House fires go down as the buildings built during this decade are renovated and the wiring gets replaced. XD

Every now and then I'm reminded Real People with Actual Jobs use tumblr and I've always been legitimately curious what all you weird adults are up to when you're not on this site and with tumblr's New Poll Feature I can finally get an answer! (or the closest approximation of an answer possible with only 10 available options h a)

They don’t even attempt to assassinate US politicians anymore. You notice that? Not since the anthrax scare back for… who was it, Barack? And even that… pathetic. This new generation has no respect for an honest hitman. I’m not sure this new generation has any honest hitman - you see that shit with Boeing? Sloppy, fucking disgraceful - you kill the whistleblowers before they get halfway to a lawsuit. What kind of fucking amateur is doing faked suicides the night before testimony? Goddamn greenhorns. Back in my day someone tried to shoot Ronald Reagan in broad daylight. There used to be bomb threats to Congress. I took out a few union leaders in the utilities sector myself. Today’s generation? Won’t even threaten to throw a punch - not even over on that - what’s it now, ‘X’? They got no guts. None! And they don’t even have poor impulse control to boot! Too much of that - that panopticon anxiety bullshit. “Oh what if I get a called out post???” People used to send the president letters full of bioweapons. In the mail! Today’s generation? Not a chance. All because of woke.

hey this post on bluesky fucking sucks.

the dishonesty here is palpable. the op of this post complained that they spent hours editing a video only for it to get 200 views. this is only important if you think views/follower counts correlate directly with income. if you want to be an influencer who makes art, just fucking say so. but this is not the point of simply "being an artist".

you absolutely do not "have" to spend hours of your day making tiktoks and reels showing your workspace and process and daily life and upcoming releases. it is a conscious decision to spend your time being an entertainer for children who consume exclusively short-form media instead of enjoying and honing your craft.

please don't let posts like this make you think that this is the "only way" of being an artist in the social media era and that if you don't document your entire process, you're some kind of failure. don't let posts like this guilt you into thinking you aren't doing enough. freelancing obviously involves marketing yourself, i'm not saying "advertising your work is bad", but if you are at any time fretting over the tedium of making a process tiktok maybe take a few steps back and evaluate if the time you are spending catering to the algorithm is proportionate to the time you are spending actually doing the things you like.

Prompt in Memes 5

Once more, have a prompt entirely in memes because I'm too lazy to properly write one right now lol.

Perhaps a Hot Take: I don't have anything against JayVik as a ship, but the amount of people in the fandom who use it as an opportunity to be openly racist and misogynistic towards Mel and Sky, and to feminize/infantilize Viktor as a disabled man make it REALLY hard to enjoy

Dp x Dc AU: Jazz Fenton, after years of fixing her brother’s injuries, becomes a Doctor with an inclination towards behavioral health and psychology- In order to make the difference she wants to see in the world she joins Dr. Leslie Thompkin’s practice. 

Jazz Fenton, M.D. has spent years of her life doing research, doing the hard work and the emotional labor, and finally, finally, she’s joining a practice she can feel 100% confident in. She’s goddamn good doctor and she wants to make the biggest impact that she can. 

Dr. Thompkins (who insists that she call her Leslie as they’re colleagues now), is a kind woman, sharp as a tack and keeps her practice open at odd hours to help the most unfortunate. It took some time for them to bond and trust to be built, but now Jazz is being allotted a few night shifts here and there. 

It’s incredible. Jazz gets to spend time with the kids who come in and really talk to them (in addition to getting them antibiotics, heating pads and pokemon themed bandaids) to help equip them with a few coping skills. Her passion for psychology never disappeared after all, but the expansive knowledge of how to heal the human body has made her find a sense of fulfillment like no other.

Having proven herself and worn Leslie down, Jazz now takes up about 1/3 of all the night shifts in the month. She’s hoping to get to 50/50 by the end of the year but she’s content with what she has. Danny keeps odd hours anyway so calling him after work on her walk home can happen any time of day and he will always answer enthusiastically. 

It��s a particularly busy night before he comes in. The Red Hood. 

He was known for being an ally to Leslie, despite being on contentious terms with the Bats, but Jazz had never asked directly. Never one to turn away a patient with bullet hole wounds, she hops into action to get his wounds cleaned, sewed up and gauze wrapped. She’s handing him a sheet (an Infographic! Dani made it with her! Graphic design is her passion!) on how to care for his wounds when he first seems to recognize that she’s not Leslie. 

“No, Of course not. I’m Dr. Fenton. I can’t blame you for not remembering but I did introduce myself as you bled in the entry way. You’re Red Hood, right?” 

“Hm. Didn’t realize the practice was expanding. Where can I find-” He grumbles before pushing her hand aside from where she had still been supporting his shoulder.

“Hold on there, mister. You’re going home, you’re following this infographic and you’re going to get some sleep.” 

“Lady you don’t know-” His voice modulated ton came across antagonistically. As if he was trying to intimidate her. Ha, Jazz rolls her eyes at the inclination.

“Who I’m talking to? Who I’m dealing with? You’re hilarious. I can eat you vigilante’s hero complexes for breakfast. Tell me who I’m calling to pick you up and then you can say thank you.” Jazz snaps at him. It really had been a long night but his whole dialogue thus far is making her a bit batty. 

“Oh really Doc? You know Leslie’s tough shit, and from what I can tell you’ve got nothing on her-” 

“Trying to make me feel insufficient when I just saved your life? That’s cute. I’m sure a lifetime of abandonment by both of your parental figures gave you that. I’m also sure that you inherited this desire to prove you’re not going to be dependent on anyone who wants to help from whoever got you dressing up in tights to fight crime in the first place. Again, I’d love to talk at length about how predictable you-” 

“Bwah- wait- I’m Predictable? You’re probably some nepobaby who had parents who told her she could have the world-” But Jazz cuts him off with hysterical laughter- he couldn’t be further from the truth. Her parents loved her, but nepotism? With what, the ghosts? If anything she got that from Danny, but he doesn’t need to know about her ghostly titles. 

“You’re just some guy who came back from the dead and made his trauma everyone else’s issue. So shut it. And tell me how I’m getting you home from this clinic.” She seethes though her voice stays devastatingly level with each word. 

Speechless for a moment, he eventually relents to Jazz that he’s already called for help on the comms but it will be hours before they can come for a pick up. The sun had already come up and the night had been over for most of them before Hood had walked into trouble. She groans and the realizes the time for herself and the empty clinic around them.

“Fine. My shift just ended anyway. I’ll get you home in one piece and I swear to all the ancients that you’d better follow the directions on the infographic.” 

And that’s how Jazz ended up calling her brother while supporting the weight of a grown ass man (who no longer wanted to talk to her) on her walk home. 

The next time Red Hood appears in her clinic, he’s brought a dozen roses in addition to the cut on his neck that definitely needs to be pressurized like ASAP. Did he stop for the flowers on his way to the clinic? He’s going to pass out from blood loss! She doesn’t even like roses!
