Hey ms sergle do you think you’ll be doing the highs or averages for your temp blanket? I know some ppl do the highs bc otherwise they rarely (if ever) get to use their highest color, so I’m curious what your plan is :0

I'm thinking I'll do the highs!! I won't be able to have the fun of charting sub-zero temps, but oklahoma still gets a lot of variation, so I should be able to use lots of colors by just going w the highs.

I have been playing Furry Paws, because I literally used to do Punnett squares for fun, and I’ve never seen another petsite with this much genetic experimentation power.  And the art is cute.

Just now I sorted some dogs by level, because I wanted to see who was getting high enough level for me to breed.  These are my highest-level Chihuahuas right now.

(side note: The three-letter code at the start of each name represents the dog’s current sports title.  Then for the actual name, I generally either use one that amuses me, or just go with the in-game randomizer.  There is one amusement name here and the rest are random.)

“Oh, but I’ve already bred Cody and Sophie,” I thought to myself.  “I’ll take a look at the others, see if it looks like their genetics line up nicely.

“Ha!  There’s a Buddy and a Holly.  Oh, and they actually would go pretty well together.  That would mean that, out of my basically-randomly-named Chihuahuas, the last potential breeding pair would be...

“.....,,.,.,,...,”

OH COME ON.  I can’t put those two together, everyone will assume the names were on purpose!!

Fake Dating tropes with (some of) the birds and the bats. Ft. Babs, Bruce, Dick, Duke, Jason, Kate, and Tim.

GN!Reader, ≈200-250 words each CWs: None graphic mentions of sex, none-graphic injuries, none -graphic mentions of drugs, intentionally minipulative behaviours.🩷

Barbara

The two of you weren’t exactly not dating. Attached at the hip, making goo-goo eyes in person and inappropriate comments over the comms line when apart; it was obvious to anyone with eyes or ears that something was going on there, you just hadn’t put a name on it yet. It’s something the two of you had made plans to nail down and discuss during your sort of but not really a date-date tonight.

But you had only gone and got yourself shot during what should have been a simple trip to the bank. It wasn’t life-threatening, but you’d been rushed off in an ambulance, you’d need surgery, a lot of meds, and months, if not years of physio to get your arms back into shape.

Barbara didn’t know that at the time though, she’d been panic-stricken from the moment she found out. Emotions getting the better of her, brain running at 100 miles a minute as she rushed to the hospital.

“Partners and family only.” The nurse had told her. And without hesitation, she’d responded: “I am their partner.”

Her lie paid off, allowing her access to your bedside, as well as a full update on your status. There wasn’t another face in any universe you would have rather seen upon waking up from surgery. Now you just had to keep up the appearance of being a married couple until you were discharged, maybe longer.

Bruce

It’s a well-organised and thoroughly thought-out publicity stunt. Bruce needed someone new on his playboy roster, and you needed the media to circulate literally anything other than the less-than-flattering leaks that had been sold to them without your consent.

All you had to do was follow the itinerary. A couple of soft launch social media pics, a few whispers to the looser-lipped socialites of your circles, and some ‘private’ candid photo ops of the two of you dating:

Snuggling under the shade of an oak tree in Gotham Park, wearing matching caps and sunglasses that do little to hide your identities as you read a shared copy of Romeo and Juliet together.

Sitting in his car, in the parking lot of Big Belly Burger, munching on an unseemly large order of burgers and fries together. Nobody questions why the previously tinted windows of Bruce’s car are now clear.

Intimately and provocatively embracing, tastefully half nude on the balcony of your uptown apartment. The press didn’t need to know that you’re actually renting an Airbnb for the weekend, for exactly this purpose, and nothing more.

Everything was carefully planned, right down to the T for maximum impact and minimal effort. The only thing that hadn’t been accounted for was one, or both of you catching feelings in the time you’d spent together.

Dick

He’s never been able to say no to you, you know it, he knows it. So when you ask him in an act of desperation to be your fake-boyfriend for your ex’s wedding he’s quick to inform you that this is the dumbest idea he’s ever heard, and that he’s 110% on board.

He takes you shopping for matching outfits, picks you up on the day in Bruce’s flashiest car, suprises you with something pretty, compliments you loudly and romantically at every chance and won’t take his hands off you all the way through the ceremony. He's attentive and outwardly passionate. Not only is he playing the role of the world's best-ever (fake-)boyfriend, he’s making sure everyone in the vicinity knows you’re a (fake) couple.

It’s during the reception when that funny feeling really starts to settle in. The hairs on edge, butterflies in your belly feeling. Maybe it’s the happy, romantic atmosphere, the soppy music, the way his hands sit so perfectly on your hips as he sways you round and around on the dance floor. Maybe it’s the way he’s looking at you with those mesmeric blue eyes but damn if you don’t want to kiss him, right here, right now.

Duke

It was a stupid idea, and his family would give him so much shit if when they found out, but you’d argued that “we’ll never know if it might actually work unless we try” and that had sold him on giving it a go. Even if he thought about calling it off at every turn.

What was the stupid plan, and why was it necessary? Well, your ex was dating his crush, and you’d figured fake-dating might redirect their attention to the two of you. And if not, no harm done, right?

Big harm done. Over the next few months, Duke and yourself had spent most of your free time in close proximity. Sharing clothes, food, and ‘plan-related’ intimate details about each other. When you weren’t together you were glued to your phone, awaiting his texts, refreshing his socials.

Somewhere amongst all the dinner dates, and ‘strictly-business’ public making out sessions, your plan worked; his crush took notice, how could they not, Duke was perfect.

Your ex did not. Not that you cared, you’d moved on, to someone who was about to become equally as unavailable.

Jason

He was trying to infiltrate an infamous drug ring so he could take it down from the inside and needed someone in the know who could double as arm candy to sell his story. You’d already been trying to get your foot in the door for weeks now, but lacked enough street cred for them to take a chance on you. It only made sense that you would join forces.

For a while it’s fun, hanging off his arm, letting his hands roam your body freely, loud-whispering all the things you wanted to do to him for anyone to hear. You really enjoyed pretending to be his devilish trophy partner. You enjoyed the nights where it wasn’t pretend even more. But all good things must come to an end.

He served his purpose of getting you where you needed to be, but now he was getting a little too close to building a compelling case against the ring, you couldn’t let that happen, you had much bigger plans for it.

What? You’d promised information, not loyalty.

Kate

You’re both socialites with fairly large internet followings who run in the same circles. Your relationship has always been that of friendly acquaintances until a photographer snaps an innocuous photo of you both entering the bathroom at the same time and the media goes crazy.

Despite putting out very clear, separate statements, clarifying that there is nothing going on, your respective followers grab the ball and sprint with it until you both innocently start to play along. Leaving flirty comments on each other selfies, acting appalled when the other is rumoured to be dating someone else, tagging each other in scenic snaps that could be considered romantic: graffiti hearts, colourful sunsets, starry skies from the candlelit table of a wine bar.

It’s completely harmless of course, it’s all a joke, until it’s not. Until you actually find yourself flustered by her comments, really wishing she was sharing your dinners, until you brace yourself and send the first DM.

Tim

He really is the whole package. Handsome, hardworking, dedicated, polite, and as smart as he is rich. You can understand why your grandma was so excited, calling you from across the country to confirm if you were the mystery person spotted out and about with Bruce Wayne’s second youngest. You hadn’t lied when you’d said yes, you’d just neglected to tell her that you were only friends. You figured it would get her off your back about finding a nice boy for a while. It kind of felt nice, talking to somebody other than yourself about your big fat crush on him and in your defence, you hadn’t expected things to escalate so quickly.

One minute she’s bragging about her grandchild’s new boyfriend to the ladies in her swim aerobics class, the next she’s booked a flight to come and visit so she can meet him.

If you’d known what she was planning you would have confessed, but she’d already forked out the cash for her plane ticket so you swallowed your pride and begged Tim to help. He wouldn’t even have to do much, just spend the weekend nodding and smiling at an old woman’s stories and then he could reap the rewards of your eternal gratitude. You’d promised 6 months of undisputed lording it over you and a lifetime of freshly made cold brew.

Smile and nod, that’s all you expect, but apparently, that was too easy. Tim just had to make what was already an embarrassing situation, a million times worse. ‘Perfect grandson-in-law’, your ass.

Red Bull’s rivals believe the team’s penalty for exceeding Formula 1’s budget cap during 2021 will not have a significant effect on their competitiveness this year. The world champions were fined $7 million and given a reduction in their aerodynamic testing allocation for over-spending in the first year F1 introduced its new cap. The sanction was announced in October last year. As fines do not count towards the cap the penalty does not reduce how much money Red Bull can spend on car development. However their aerodynamic testing allocation, which was already the lowest of any team this year, was further reduced, from 70% of the reference total to 63%. Ferrari have the next-lowest allocation on 75%, with Mercedes on 80%. However Mercedes team principal Toto Wolff says the fact Red Bull were so competitive last year means they will begin the new season in a strong position regardless of the restriction. Red Bull had a 0.5s advantage last year, says Wolff “They’ve done a very good job last year in getting and putting a car out there that is half a second or more quicker than everybody else,” said Wolff. “I think the lack of wind tunnel time is certainly not great for them, [it’s] an advantage for us this season. “But if you have an efficient machine, you can certainly compensate for that, or large parts of it. So, long term, [it’s] good for us.” Under the Aerodynamic Testing Restriction the team which finishes highest in the championship has the smallest development allocation the following season – a challenge Mercedes faced last year after winning the 2021 constructors title. Advert | Become a RaceFans supporter and go ad-free “We’ve been in that situation, obviously without a penalty, in the years before,” said Wolff. “We’ve won, and therefore we had less wind tunnel time than everybody else for the last two seasons. “It’s going to certainly bite them a bit, but if they’re efficient as an organisation which they’ve demonstrated, it’s not going to be big.” Former Red Bull designer Dan Fallows, who is now at Aston Martin, said the champions have “a great deal of strength in depth” which will allow them to “minimise the impacts of that penalty.” Alpine team principal Otmar Szafnauer, who is counting on the ATR to help his team close its deficit to the top three this year, said it was hard to predict the likely impact of Red Bull’s penalty. “It definitely won’t help” them,” said Szafnasuer. “That’s still one of the biggest areas of development, to have that restricted will definitely hamper them. By how much. I don’t know.” Asked whether their penalty should have been tougher, Szafnauer said: “I’m not at Red Bull [so] I’m always going to say it should have been bigger.” Red Bull team principal Christian Horner said the lower limit they will operate under is “a significant handicap that we carry for the majority of the year.” The team is yet to publicly reveal its RB19 chassis for the upcoming season, having presented a show car at its launch event in New York, though the car has already run in private at Silverstone. *Due to their penalty for exceeding the budget cap in 2021, Red Bull’s allocation this year is reduced from 70% to 63% Bringing the F1 news from the source RaceFans strives to bring its readers news directly from the key players in Formula 1.

MOST ICONIC BIRD CALL BRACKET: ROUND ONE: COMMON LOON vs. BLACK CAPPED CHICKADEE

IN THE BLUE CORNER, we have the master of the waves, the king of the lake, the COMMON LOON!

this bird is a true lunatic. this bird is a true master of the water, and his haunting calls can be heard echoing across the lakes and ponds of north america. this is a fierce competitor that always gives 110% in the ring. get ready for some aquatic action, folks, because the common loon is about to take flight and deliver some serious punishment to its opponent.

IN THE RED CORNER, we have the high-energy, high-flying, and high-pitched wrestler, the black capped chickadee!

this cold-weather bruiser is well loved among backyard birders for its charming chirps and its boldness around humans - excited fans report being able to feed chickadees by hand. this little dynamo's calls are highly complex, able to communicate different types of information to members of its flock. most well-known is the "chick-a-dee-dee-dee" call that gives this wrestler its name. it sounds simple, but this call has been the subject of research since the 1970s due to its complexity. this call can be arranged in different patterns to communicate information about threats from predators and coordinate group movements. watch out, because the black capped chickadee is one fierce competitor that won't back down from any challenge.

[prokopetz]

The reason why we're suddenly seeing a bunch of indie video games – particularly American indie video games – using vintage music is because the US finally has a public domain in sound recordings.

For context, until 1972, there was no federal copyright regime in the US for sound recordings; intellectual property law for sound recordings was devolved to the individual states, meaning there were fifty different sets of rules that might apply to any given recording, and some states allowed sound recordings to be protected for an indefinite term – i.e., in essence, perpetual copyright without expiration.

What changed in 1972 was the Sound Recording Amendment, which established unified federal copyright on sound recordings for the first time, but which allowed any pre-existing state-level copyrights for sound recordings published prior to February 15th, 1972 to run for their full term. Since most state-level sound recording copyrights had no fixed term (see above), this was capped at the "publication plus 95 years" rule which applies to other federal copyrights – with the twist that the 95-year cap on previously perpetual sound recording copyrights would count from 1972, not from the date of publication.

This effectively meant that no sound recordings in the US would enter the public domain until February 15th, 2067 – which doesn't do anyone a whole lot of good right now!

Fast forward to 2018, when another piece of federal legislation, the Music Modernisation Act, was passed. Though this act was mainly concerned with streaming royalties and such, it also contained provisions to grandfather certain sound recordings into the public domain earlier than the Sound Recording Amendment's all-or-nothing 2067 deadline. Specifically:

On January 1st, 2022, all sound recordings published before 1923 would enter the public domain

Sound recording published from 1923 through 1946 will enter the public domain 100 years after the date of first publication

Sound recordings published from 1947 through 1956 will enter the public domain 110 years after the date of first publication

In practice, what this means is:

All sound recordings first published before 1923 entered the public domain last year, on January 1st, 2022;

This year, 2023, is a "gap year" in which no sound recordings enter the public domain (i.e., being the 100th and final year of protection for sound recordings first published in 1923); and

On January 1st of next year – that is, January 1st of 2024 – new batches of sound recordings will begin to enter the US public domain on a yearly basis for the first time in history, starting with sound recordings first published in 1923.

adventures in QA

(previous post in this series)

My shop in Advanced Midbody - Carbon Wing (AMCW) at Large Aircraft Manufacturer (LAM) is at the very end of the composite fabrication building. Hundreds of people carefully lay up a hundred foot long slab of carbon fiber, cure it, paint it, and then we totally fuck it up with out of spec holes, scrapes, primer damage, etc. The people who write up our many defects are from the Quality Assurance (QA) department.

Every single screw and rivet on a LAM aircraft can be traced back to the mechanic who installed it. Back when even everything was done in pen and pencil, it was joked that the paper used to produce an aircraft outweighed the plane itself. Now that everything is computer-based, of course, the amount of paperwork is free to grow without limit.

(Haunting the factory is endless media coverage of an emergency exit door plug popping out of an Advanced Smallbody - Upengine (ASU) plane during a routine flight a few months ago. Unlike that airframe's notorious problems with MCAS, this was a straightforward paperwork screwup by a line worker: the bolts were supposed to be tightened, and they weren't.

As a result the higher ups have visited hideous tribulations on non-salaried workers. Endless webinars, structured trainings. Here at the Widebody plant we have received a steady flow of refugees from the Narrowbody factory, hair-raising tales of receiving one hundred percent supervision from the moment they clock in to the second they clock out from FAA inspectors who can recommend actual jail time for any lapse in judgement.)

A single hydraulic bracket Installation Plan (IP) is around four brackets. The team leads generally assign two bracket IPs per mechanic, since each bracket set is something like a foot apart, and while working on the plane is bad enough it's much worse to have another mechanic in your lap.

Let me list the order of operations:

One: Find where you're supposed to install these brackets. This is harder than you might think.

Firstly, it's a hundred foot long plank of carbon fiber composite, with longitudinal stringers bonded to it to add stiffness. The stringers are pilot drilled in the trim and drill center, a truly Brobdingnagian CNC mill that trims off the composite flash at the edges and locates and drills part holes for us. But there's a lot of holes, so you must carefully find your set.

A minor difficulty is that the engineering drawings are laid out with the leading edge pointing up, while the wing panels in our cells hang from the trailing edge. Not so bad, you just rotate the paper 180 when orienteering, then rotate it back up to read the printed labels.

A major difficulty is that the drawings are from the perspective from the outside of the panel. But we work on the inside of the wing (obviously, that's where all the parts are installed) so we also flip the drawings and squint through the back of the paper, to make things line up.

Large Aircraft Manufacturer has a market cap of US$110 billion, and we're walking around the wing jig with sheets of paper rotated 180 and flipped turnways trying to find where to put brackets.

Oh well, we're paid by the hour.

Two: Match drill the aluminum brackets to the carbon fiber composite stringer. I can devote an entire post to the subtleties of drilling carbon fiber, but I can already tell that this post is going to be a miserable slog, so I will merrily skip over this step.

Three: Vacuum up all the carbon dust and aluminum swarf created during this process. This step is not optional, as your team lead will remind you, his screaming mouth clouding your safety glasses with spittle at a distance of four inches. LAM is very serious about FOD. Every jet airliner you've ever ridden in is a wet wing design-- each interstitial space is filled with Jet A. There is no fuel bladder or liner-- the fuel washes right over plane structure and wing hardware. Any dirt we leave behind will merrily float into the fuel and be sucked right into the engines, where it can cause millions in damage. No place for metal shavings!

If you are nervous about flying, avoid considering that all the hydraulic lines and engine control cables dip into a lake of a kerosene on their way from the flight deck to the important machines they command. Especially do not consider that we're paid about as much per hour as a McDonalds fry cook to install flight-critical aviation components.

Four: Neatly lay out your brackets on your cart, fight for a position at a Shared Production Workstation (SPW) (of which we have a total of four (4) for a crew of thirty (30) mechanics) and mark your IP for QA inspection as Ready To Apply Seal.

Four: Twiddle your thumbs. Similarly, we have three QA people for thirty mechanics. This is not enough QA people, as I will make enormously clear in the following steps.

Five: Continue waiting. Remember, you must not do anything until a QA person shows up and checks the box. Skipping a QA step is a “process failure��� and a disciplinary offense. From the outside, you can observe the numerous QA whistleblowers and say “golly, why would a mechanic ever cut a corner and ignore QA?” Well...

Six: QA shows up. Theoretically, they could choose to pick up the mahrmax you prepared for them and gauge every single hole you've drilled. But since we're three hours into the shift and they're already twenty jobs behind, they just flick their flashlight across the panel and say “looks good" and then sprint away. Can't imagine why our planes keep falling out of the sky.

Seven: Apply the seal to the bracket. P/S 890 is a thick dark gray goop that adheres well to aluminum, carbon fiber, fabric, hair and skin. Once cured, it is completely immune to any chemical attack short of piranha solution, so if you get any on yourself you had better notice quick, otherwise it'll be with you as long as the layer of epidermis it's bonded to. LAM employees who work with fuel tank sealant very quickly get out of the habit of running their hands through their hair.

Eight: Now you wait again. Ha ha, you dumb asshole, you thought you were done with QA? No no, now you put up the job for QA inspection of how well you put the seal on the bracket. Twiddle your thumbs, but now with some urgency. The minute you took the bottle of seal out of the freezer, you started the clock on its "squeeze-out life." For this type of seal, on this job, it's 120 minutes. If QA doesn't get to you before that time expires, you remove your ticket, wipe off the seal, take another bottle out the freezer, and apply a fresh layer.

Nine: Optimistically, QA shows up in time and signs off on the seal. Well, you're 100 minutes into your 120 minute timer. Quickly, you slap the brackets onto the stringer, air hammer the sleeve bolts into position, thread nuts onto the bolts, then torque them down. Shove through the crowd and mark your IP "ready to inspect squeeze out"

Ten: Let out a long breath and relax. All the time sensitive parts are over. The criteria here is "visible and continuous" squeeze out all along the perimeter of the bracket and the fasteners. It is hard to screw this up, just glop on a wild excess of seal before installing it. If you do fail squeezeout, though, the only remedy is to take everything off, throw away the single-use distorted thread locknuts, clean everything up and try again tomorrow.

Eleven: QA approved squeeze out? Break's over, now we're in a hurry again. By now there's probably only an hour or two left in the shift, and your job now is to clean off all that squeeze out. Here's where you curse your past self for glopping on too much seal. You want to get it off ASAP because if you leave it alone or if it's too late in the shift and your manager does feel like approving overtime it'll cure to a rock hard condition overnight and you'll go through hell chipping it off the next day. You'll go through a hundred or so qtips soaked in MPK cleaning up the bracket and every surface of the panel within three feet.

Twelve: Put it up for final inspection. Put away all your tools. (The large communal toolboxes are lined with kaizen foam precisely cut out to hold each individual tool, which makes it obvious if any tool is missing. When you take a tool out, you stick a tool chit with your name and LAMID printed on it in its place. Lose a tool? Stick your head between your legs and kiss your ass goodbye, pal, because the default assumption is that a lost screwdriver is lurking in a hollow "hat" stringer, waiting to float out and damage some critical component years after the airplane is delivered.)

One tool you'll leave on your cart, however, is the pin protrusion gage. There is a minimum amount of thread that must poke outside of the permanent straight shank fastener's (Hi-Lok) nut, to indicate that the nut is fully engaged. That makes sense. But there's also a maximum protrusion. Why?

Well, it's an airplane. Ounces make pounds. An extra quarter inch of stickout across a thousand fasteners across a 30 year service life means tons of additional fuel burnt. So you can't use a fastener that's too long, because it adds weight.

On aluminum parts, it's hard to mess up. But any given composite part is laid up from many layers of carbon fiber tape. The engineers seemed to have assumed that dimensional variation would be normally distributed. But, unfortunately, we buy miles of carbon fiber at a time, and the size only very gradually changes between lots. When entire batches are several microns oversize, and you're laying up parts from fifty plies and an inch thick, you can have considerable variation of thickness on any given structural component. So you had better hope you had test fit all of your fasteners ahead of time, or else you'll be real sorry!

And, if you're really lucky, QA will show up five minutes before end of shift, pronounce everything within tolerance, then fuck off.

And that's how it takes eight hours to install eight brackets.
