Hedy Lamarr was born Hedwig Eva Kiesler in Vienna, Austria on November 9th, 1914 #botd Actor, legendary beauty, and inventor who pioneered the technology that would one day form the basis for today’s WiFi, GPS, and Bluetooth communication systems.

It's no wonder Out happened when you really think about it. Nastya doesn't like organic life because it's complicated, it can break, sometimes it's even unfixable.

quote from gender rebels

Nastya is in love with Aurora, and in saying that she is saying "you are not organic life, I can deal with you because you are metal and algorithm and predictable" - we can see this in bedtime story when she says she'll tweak Aurora's story creation algorithm

screenshot from A Bedtime Story

Aurora is not inorganic. She is not ai. She is a space moon made of flesh and blood and teeth and bone. She is not an ai. She is a body that was taken and stripped of autonomy, of the right to self identify, of the right to think- to be imperfect and organic.

The metal is a veneer that hides how messy and traumatized and unfixable she is. From the outside she is a starship. From the inside she can still bleed.

And this makes them fundamentally incompatible. But yet, they are in love.

And really, it's no wonder Nastya fell in love with Aurora. Let's take a look at Nastya's home planet, or at least home society:

"Terminals were scattered across the planet. There was one on every street corner, one beneath every lamppost and one in every commune block." "The midwife-machine performs a series of programmed manœuvres to quieten [the baby]. It cradles it and hums at several pitches until it finds one that seems most soothing. Mechanical arms stroke the baby’s flesh even as others start the process of implanting augmented reality interfaces into its nervous system." "The Czar an atrophied frame, never present in the real world and worn to dust by the chemical compounds that kept his brain alive so it could live forever in a perfect virtual paradise. The Rabotnik a copy, a mind preserved unchanging in the instant before its death and placed in an everlasting metal frame." (Cyberian Demons)

Its safe to say the world Nastya was born into, from the very minute she was born, was ridden with technology. She has augmented reality interfaces inplanted into her from birth. It would stand to reason that being taken from this society, wherein technology is everywhere, inside and out, would stand for a bit of a shock.

Aurora too had been augmented by the Cyberia.

While it is stated that the last time Nastya had used the ports themselves was directly before her death — "The last time she had used the ports, her tutor had ripped them out of her as the rebels stormed the palace" — Aurora is laced with Cyberian technology. I'd imagine she has something of a 'bluetooth wireless connection' with Aurora, rather than the physical data transfer of files between the ports and Nastya, it may as well be similar enough.

Imagine being Nastya, going from Cyberia, wherein there is augmented reality contantly, transplanted onto a ship with metal blood, a jonny, and a vampire. To Aurora, where the only bits of augmented reality run through Aurora.

Of course she'd fall in love with her. Aurora is familiarity. Aurora isn't organic. Aurora isn't human.

And of course when the undeniable part of aurora that is organic, that is a flesh moon plated in metal with her brain hooked to machines, when so much has broken and been replaced, when, presumably, aurora is less of an algorithm, nastya leaves with the brand cyberia left on her.

Because Aurora healing, becoming more of herself and less of a starship, is messy, and organic, and human.

and hard for nastya.

‘Think how long she’s been flying you around. Think how many bullet holes you’ve punched through her and how many atmospheres you’ve dropped her through. Think how many alterations and improvements we’ve made, Tim to her guns and Ashes to her storage and Brian to her engines and the Toy Soldier to who knows what. How much do you think is left of her after all she’s brought you through?’ Nastya held up the ancient, battered piece of hull plating. Just visible under the grime and scars of particles of space junk was a fragment of the Aurora’s original logo and serial number. Jonny honestly couldn’t remember the last time he had seen a version that hadn’t been painted by the Mechanisms themselves. ‘So she’s free, now.’ Nastya gestured around at the spaceship they were standing in. ‘This Aurora can take you where you want to go. I’m going to take my Aurora somewhere else.’

Aurora was ship of theseus'd. Aurora was improved. Aurora was no longer cyberian. (both literally, and metaphorically)

So nastya left.

Hedy Lamarr was considered one of the most beautiful women in Europe. Born Hedwig Eva Maria Kiesler in 1914 to a Jewish family in Vienna, Austria-Hungary, she became a film star in Europe by the 1930s, and soon after, she achieved similar recognition in the U.S. In addition to her acting career, Hedy pursued inventing.   Motivated to assist U.S. efforts during WWII, she focused on designing a radio guidance system for Allied torpedoes that would counter the threat of jamming.   Although her innovation was not used during the war, the principles she developed are now integrated into modern technologies such as Wi-Fi, CDMA, and Bluetooth.   On August 11, 1942, Hedy Lamarr was granted a patent for her revolutionary “frequency hopping communication system,” which forms the basis of much of today’s wireless technology. In recognition of her achievements, she was inducted into the National Inventors Hall of Fame in 2014.

HISTORY TW INFIDELITY

Though she was born in Philadelphia, Daphne will always consider New York City her home. Moving at the age of six, the first time her father stayed in her life for more than a day at a time, New York represented what she’d hoped would be a fresh start with a complete family. At the very least, it was a fresh start.

Daphne thrived in New York, revelling in a vibrant social life and academic success all through her school years.

Her home life isn’t so pretty, though. She and her parents benefit from an inherited wealth, but it seems even money can’t fix a plethora of communication problems and her father’s inability to commit to absolutely anything — what to have for dinner, promises to be at her upcoming poetry slam, her mother. But she never had convincing enough evidence, and her mother always seemed to forgive him, so who was she to say anything?

For years, she watches her mother love a man who doesn’t deserve it, and slowly grows to resent him herself for the secrets he keeps and the promises he always breaks. At fifteen, she stops calling him ‘dad’. He stops interacting with her unless necessary. Her mother tries to pick up the pieces.

At eighteen, she chooses to stay in New York for university despite it all, majoring in secondary education, specialising in mathematics. Teaching is the goal, encouraged by her mother, but by the time she starts to question if it’s really what she wants, she’s in too deep.

By graduation at twenty-two, she desperately needs a break from the education system and spends her summer working the local barista job she’d used to keep herself afloat during her degree. Her mother worries endlessly that she’s lost all ambition for life, but Daphne reassures her she’s only lost maybe seventy to eighty per cent and she’ll probably bounce back soon.

She does a year or so later, when an opening pops up at an independent small group and one-on-one tutoring company. It’s perfect — all the things she loves about teaching, without the classroom full of rowdy thirteen year olds. Once again, she thrives. For now.

At twenty-six she moves out into her own apartment, finally free to exist without her father’s presence looming over her shoulder. That is until her parents’ marriage finally implodes a year and a half later, her mother finally seeing for her own eyes the man her father had always been — a liar and a cheat; a fraud.

Turns out, she’s not the only child he has. Somewhere out there is an older half brother neither Daphne or her mother have ever met. He insists that’s it, just the two, and for now, she chooses to believe him. Her mother is distraught, and Daphne bites her tongue not to say I told you so.

She spends the next six months looking for her not-new new brother and preparing. How do you tell a complete stranger that you’re siblings, sharing a sad excuse for a father? How can she even be sure he doesn’t know about her? What if he didn’t want to know? And yet, she gets on that flight with a trickle of hope that this is the right thing to do — and maybe even another chance at that ’complete family’ fresh start she’s always dreamt of.

TRIVIA

Loves 80s and 90s disco & dance music.

Can’t drive; used to cycle everywhere in NYC.

Her prized possession is a retro-style boombox with a cassette player and bluetooth connectivity. She’s had to repair it a few times and will continue to until she’s priced out of the parts she’ll need.

She only moved into Sunset Villas in March 2025, having spent the first almost-three months of her time in Palm View in a hotel.

It's only the last few months that she's began to question once again if teaching is for her. She's torn between feeling like she's never considered anything else, her mother having always told her she'd be the perfect teacher, and wondering if she never did explore her options because it was the perfect choice. She still feels like she's in too deep to do anything else either way.

Hi. I saw ur iterators and they look cool i wanna know the lore(tm)

OOO YES YES! Imma ramble about off the string au too, so putting the explanation of the au before oc lore, if you want to hear just about the oc, feel free to skip the off the string hcs! (note: a lot of my oc lore is rather long, and hard to type out in one go, i will most likely be typing up about an oc with shorter lore)

So first; how does off-the-string work in my au/hcs:

The consciousness and subconsciousness are evenly spread out throughout all of the iterator's systems and mechanisms! Usually the puppet is just used for communication, and to express the iterator's personality. Without the puppet it would be rather difficult to communicate. Now you see: the puppet can be detached from it's mechanical arm, this is most often done in maintenance or during really fancy ceremonies. To go off the string, you need to put your whole consciousness into your puppet, and then detach it from the mechanical arm. The structure would still be up and performing vital functions, however would be in a "sleep" state. You can still vaguely feel your structure if you are off the string.

Although this sounds easy, it really isn't. Since the iterator as a whole is HUGE, they'd need some time to adapt to the limitations of the puppet. They are now on the same level as an ancient, or the animals that walk beneath their structure, which can be rather difficult to adjust to if you're used to being a mechanical god. (think of it like putting all your consciousness into the tip of your finger, you're so so much smaller and vulnerable now) Note: the iterator is also now hyper-aware of their puppet since all of their consciousness, and thus attention, is in their puppet (instead of being spread out like in the structure). (Also another small note I am unsure of where to put: in my hcs, the iterators sort of have a connection to their neurons similar to bluetooth, which means that if the structure is still standing, they do not need to take their neurons along while going off the string, as they'd already have that long distance connection to the neurons) If a disconnection is done right, it is 100% reversible! Just attach the puppet back to it's mechanical arm, and everything would be just like before the iterator detached it's puppet. However if an iterator disconnected improperly, it will be rather difficult to spread their consciousness back through their structure. Also if you die off the string, your consciousness will simply go back to your structure, and you'd need to make yourself a new puppet.

As for why an iterator would need to go off the string:

Many many reasons, some iterators are just curious, others want to see if they can ascend (any void related death will cause ascension for ancients and biological organisms. Several iterators have tried to test if they'd ascend by losing their puppet to the void sea.), and some have been falsely advertised to. Not too long after Sliver's ascension, there was an event labeled the "Disconnection Obsession", where iterators would go off the string to test the aforementioned theory. However there was also a rise of false advertising, with off the string being painted as a vacation or a new solution, and of course you'd want a vacation after some real boring work. Unfortunately off the string is far from a vacation...

Onto OC lore:

I'll be talking about CV! As it's lore is currently one of the only things thats on my mind, and that I can coherently tell through one ramble. Following the disconnection obsession event, CV had gone off the string to test out if the theory of losing your puppet to the void sea will ascend an iterator (probably not be at least CV is being hopeful). Or well, it more so thought it needed to test out this theory. Unfortunately CV was brainwashed by it's council to have the extremist ascensionist views of the world. Deep down it never really had any interest in ascension, it had more interest in archiving religious history to be honest. So CV went off the string with it's neighbors (Visions of Issues Unforeseen, Grim Speculations), and originally it planned to go to the void sea, but overtime it wanted to stay with it's neighbors more (who it became rather good friends with). I nicknamed the trio "The half-group", since originally they were a separate group from DAWNS_ABOUND, before the two groups merged for political allyship back when the ancients were around. Putting this map here as well! The two collapsed iterators near the half-group are early prototypes, who collapsed even before GS (oldest of the half-group, the second model of gen 2 ever made) was built. Early prototypes never really have a long lifespan unfortunately.

Thats about it for now!

Okay, so how does the bat communication system work

They could use signal but tbh. That might be to much functionality on what we would need.

Authentication is like in this case pretty trivial, because they are like 2 dozent people who can all be in the same room at some time and get their devices in person. Maybe they have some kind of rsa token for that. And also they build their own devices (again like 2 dozent or something so)

Also the serverlessness of signal is great, if you dont want your data in some server, but also again. They probably have their own servers anyway. And soemtimes the bat communication network is written like if someone is offline they just never get the message so very normal client2client would work.... I would prefer using the batservers instead however.

Anyway so the signal protocol implements perfect forward secrecy (so if the key got into attackers hands the earlier send messages are save) and perfect backwards secrecy (future messages are safe). So you would keep these parts...

Because again they are only like max 2 dozent people the major drawback of signal (it not scaling well for big group communications) this also does not apply.

Okay now to the part of the wireless communication.... We do have the problem here that most of batman canon is before 2018. After thinking a lot about that and crying a bit i decided, to make any of this work we have to make an au in which Wayne enterprises build a 5G network in gotham in the 90s. In this au 5G would be the first one someone invented, so downgrade attacks would not work.

I also asked my friend for suggestions and he said maybe Wayne Enterprises did build a totally second Network additionall to the normal Gotham wireless network with own bts for the bats. And so the bats can just use their own build protocoll (using Dragonfly and ECDH). The Batman Protocoll would use own headers so the normal bts will just ignore that, and we will encrypt the header, so the headers can not be tracked.

I know some 90s comics also said Oracle is talking to the bats per phone, but for the sake of my sanity we are ignoring that.

Anyway so what do the bats for sure not use:

Fax: many things which irl would need to be somewhat private are send over fax, because this is client2client and not saved on any servers which belong to some external company. However!!! It is also not encrypted and just sends the message on clear text. Everyone with access to the connection could just read that

Wifi (i mean. the batcave might be bigger than 50 meter radius so, maybe they can actually use it there.)

Bluetooth

SMS

like normal phone calls

Ship Chase

@silver-blooded-synthetics w/ Alien!Alma and Rachel

It had been a decent while since Rachel had first discovered the injured alien in her backyard. A few months, if she had to guess? Long enough for an entire winter to pass at the bare minimum. Once he was healed, they went to find his ship and ensure that it was safe and secure (and, most importantly, hidden). Once they were able to confirm that it had suffered no damages upon arrival to Earth, they safely hid it away and Alma carefully made note of where its specific coordinates were the next time they had to find it.

In the months that followed, he had essentially been her housemate. It was a bit of an adjustment, at first, but Alma very quickly became easy company to have. It was strangely easy to get used to having him around, once Rachel was able to set up a surround sound speaker system in her house that was able to be connected to through Bluetooth to make communicating with her as easy as possible. Technomorphs, as they were called, were a fascinating species.

Of course, she couldn't reasonably take him out during the day. Not until she was comfortable enough to be able to do so without risking physical injury to him by passersby. And since the winter had closed in on them, she didn't want to risk him getting hurt by the cold. So, during the winter, whenever she was home, she spent her time with him. She had to admit...it was nice having someone else living with her. Her house felt significantly less empty.

But now that the snows and ice had thawed and winter had swiftly made its exit, the pair of them now located Alma's ship once more to check on it and perform a routine diagnostic, especially with the weather it had endured. The ship was apparently as sentient as Alma was, functioning more as a steed of sorts as the closest human equivalent than a ship while still being technological in nature, much like Alma himself.

It fascinated her to no end...and she wanted to learn as much about it for herself. And she wanted to make a good impression on it, so she tried to be as helpful to Alma as she could while he checked to make sure everything was as it should be. They did this during a particularly warm night to be as less disruptive as possible.

The interior of the ship was just as fascinating to her, of a similar aesthetic to Alma himself. It thrummed to life once they boarded and even while walking through it, she could feel the life that emanated from it. Such a fascinating thing, almost like living technology in a way...she couldn't help but constantly shower compliments on it as they navigated the ship, Alma guiding her as they did so.

"So, anything out of sorts so far that you can tell?" Rachel asked, wanting a baseline for what to expect and what sorts of oddities she needed to look for that Alma should be made aware of.

LakeTahoe!Series:

Part One: Black Bear Lodge - Your life changes when you meet Manny at Black Bear Lodge.

Part Two: Something Special (NSFW) - Manny gives you a night like no other.

Part Three: Goodbye - You and Manny say goodbye after spending the weekend together.

Postcards: Manny recieves a surprise in the mail.

It’s over a four-hour ride to L.A. Manny’s arranged to stay a couple of days with you before he needs to be in Santo Padre to discuss the pipeline deal with Bishop. It’s become clearer over the past few weeks that Canche has been subsidising his income with club funds. They’re missing a massive portion of cash and that means they can’t buy into the pipeline.

On the drive up he starts to think of it as a blessing in disguise because it allows him to think outside the box, to consider other options. He wants more for Yuma, he wants better, safer options for his brothers, ones that won’t result in prison or a bullet. Santo Padre has been heading that way for a while, they have links to the community, they work with legitimate businesses, their income is clean and constant. Manny wants to emulate that.

He’s exhausted by the time he makes it to your suite; he uses the key you’ve left for him down at reception. It’s a little past ten pm and the day has taken its toll on him. He’s been up since six getting Melina ready for school and dealing with club business, all he wants is to sooth his aching muscles in a red-hot bath.

The lights are dimmed when he steps inside. He removes his boots by the door before padding quietly into the bedroom. They’ve gone all out this time; he thinks as he pauses for a second surveying the view from the window. In the distance he can see the San Gabriel Mountains silhouetted against the night sky.

Everything about this room screams indulgence, the well-made luxury furniture, the dark wood floors, the gourmet snacks in the minibar. It piques his curiosity because he knows you’re getting by on a freelancer’s wage, and he can’t imagine that any magazine would put you up in a place like this, no matter how good your work is.

He finds you in the bathroom, soaking in a tub that large enough to fit another two people inside. You have a glass of whiskey in your hand, classical music serenading you from the Bluetooth speaker in the mirror. You watch as he undresses, his dark eyes fastening on yours as his clothes fall into an untidy pile at his feet. You shift forward and he slips in behind you, the water raising over his weary bones. He exhales at the sensation, sinking low. You lean back against this chest, placing the whisky glass in his hand and he sighs because as relaxed as he is right now, he can’t shake that niggling feeling that this is all to good to be true. He lips brush over your temple, his cheek coming to rest upon your hair as he says.

“I need you to tell me why we’re here tonight because I know that neither of us can afford a suite with a mountain view.”

“It’s comped.” You tell him, tilting your head up so you can meet his gaze.

“Not by your magazine.” He murmurs, his thumb ghosting along the line of your jaw. “These rooms cost nearly two grand a night.”

“No.” You whisper as his lips brush over yours. “A private collector wants to buy my photographs, they’re exhibiting at the Hive Gallery tomorrow, this trip is his way of wooing me.”

“Will you sell?” Manny asks and he feels you smile against his mouth.

“I’m donating them to Arts+Practice, they have a lot of great art programmes for kids in the foster system.” You tell him as he graces your skin with a featherlight kiss. “He thinks he has four days to chance my mind.”

He grins because you, you are just full of surprises.

“I’m sleeping with a hustler.” He murmurs before he kisses you properly.

There’s a softness in it, a tenderness that he reserves only for you. You sigh at the sensation and it’s a noise of contentment, one that he feels in the very depths of his soul because now he knows the truth he can actually relax. He tips his head back and closes his eyes, the water washing over him as the fatigue overtakes him.

“I’m tired tonight.” He tells you, his voice drowsy as your head comes to rest in the crook of his neck.

“Me too.” You mumble. “All that travelling is starting to catch up with me.”

It changes things. If this was supposed to be about sex you would have kicked him out by now or at least made a move, but you haven’t. It means you’re as comfortable with this shift as he is. This thing between you it was always more, this is just your way of acknowledging it. He knows guys who would drive almost three hundred miles for pussy but there’s not many who would do it just to spend the night sleeping next to their lover.  

That’s how the evening ends, you and him curled up in a bed that costs more than your annual salary, his face buried in the curve of your throat as he holds you close.

It’s the best night’s sleep he’s had in a long time.

Love Manny? Don’t miss any of his stories by joining the taglist here.

I don't know if this might be a dumb question, but I'm curious

What are Donnie's headphones connected to exactly?

Oh, that’s a really good question, actually! And a fun one!

Right now the answer is: literally nothing.

Once upon a time, however, the headphone cords attached to his battleshell so they could connect to the battery/computer/processors there. Every piece of tech that Donnie wears, especially in the Nexus, he made himself and he made to fit his exact needs. It’s incredibly important to him, and his headphones have always had special settings and functions to allow him to both block out noise and prevent overstimulation as well as communicate more effectively with Leo mid-battle. The programming can filter out the crowds but recognize his twin brother’s voice, so they can talk to each other in the Nexus. And while Donnie has always obviously been an engineering genius, he also made the original design when he was eleven. Back then, he didn’t quite have the experience or skill needed to make a wireless system of that caliber and level of sensitivity with a connection he could rely on 1000% of the time. There’s no space for Bluetooth errors or radio feedback when you’re fighting in the Nexus. So, he made them wired instead, connecting directly to the battleshell that housed all the actual software/programs/etc to ensure they never unpaired, lagged, or glitched out on him.

Since then, he’s improved enough that setting up a wireless system like this is child’s play. But at that point, the public was used to Donnie’s ‘headphone wires’ and they were considered an iconic part of the outfit, so…

He kept them! (He’s not allowed to get rid of them, actually. They’re a part of the BRAND.) The wires now are completely useless and only there for show, and they tuck into his pockets rather easily, where he had some small hooks sewn where the wires can be “docked” so to speak.

Pebble the wearable back from a long death

I started working on Pebble in 2008 to create the product of my dreams. Smartwatches didn’t exist, so I set out to build one. I’m extraordinarily happy I was able to help bring Pebble to life, alongside the core team and community. The company behind it failed but millions of Pebbles in the world kept going, many of them still to this day.

I wear my Pebble every day. It's been great (and I'm astounded it’s lasted 10 years!), but the time has come for new hardware.

You’d imagine that smartwatches have evolved considerably since 2012. I've tried every single smart watch out there, but none do it for me. No one makes a smartwatch with the core set of features I want:

Always-on e-paper screen (it’s reflective rather than emissive. Sunlight readable. Glanceable. Not distracting to others like a bright wrist)

Long battery life (one less thing to charge. It’s annoying to need extra cables when traveling)

Simple and beautiful user experience around a core set of features I use regularly (telling time, notifications, music control, alarms, weather, calendar, sleep/step tracking)

Buttons! (to play/pause/skip music on my phone without looking at the screen)

Hackable (apparently you can’t even write your own watchfaces for Apple Watch? That is wild. There were >16k watchfaces on the Pebble appstore!)

Over the years, we’ve thought about making a new smartwatch. Manufacturing hardware for a product like Pebble is infinitely easier now than 10 years ago. There are plenty of capable factories and Bluetooth chips are cheaper, more powerful and energy efficient.

The challenge has always been, at its heart, software. It’s the beautifully designed, fun, quirky operating system (OS) that makes Pebble a Pebble.

Today’s big news - Google has open sourced PebbleOS!

PebbleOS took dozens of engineers working over 4 years to build, alongside our fantastic product and QA teams. Reproducing that for new hardware would take a long time. 

Instead, we took a more direct route - I asked friends at Google (which bought Fitbit, which had bought Pebble’s IP) if they could open source PebbleOS. They said yes! Over the last year, a team inside Google (including some amazing ex-Pebblers turned Googlers) has been working on this. And today is the day - the source code for PebbleOS is now available at github.com/google/pebble (see their blog post).

Thank you, Google and Rebble! I can't stress how thankful I am to Rebble and Google, in general and to a few Googlers specifically, for putting in tremendous effort over the last year to make this happen. You've helped keep the dream alive by making it possible for anyone to use, fork and improve PebbleOS. The Rebble team has also done a ton of work over the years to continue supporting Pebble software, appstore and community. Thank you!

In addition to PebbleOS, we’ve been supporting development of Cobble, an open source Pebble-compatible app for iOS (soon) and Android (works great today, it’s my daily driver).

We’re bringing Pebble back!

I had really, really, really hoped that someone else would come along and build a Pebble replacement. But no one has. So… a small team and I are diving back into the world of hardware to bring Pebble back!

This time round, we’re keeping things simple. Lessons were learned last time! I’m building a small, narrowly focused company to make these watches. I don’t envision raising money from investors, or hiring a big team. The emphasis is on sustainability. I want to keep making cool gadgets and keep Pebble going long into the future.

The new watch we’re building basically has the same specs and features as Pebble, though with some fun new stuff as well 😉 It runs open source PebbleOS, and it’s compatible with all Pebble apps and watchfaces. If you had a Pebble and loved it…this is the smartwatch for you.

More info to come soon! Follow the fun with @ericmigi and @pebble.

Are you like me?

Do you have a hole in your heart (and on your wrist) that hasn't been filled by any other smartwatch?

FAQ

When can I buy one?

As soon as we nail down the product specifications and get a firm idea of the production timeline, we'll share it with everyone on the list and invite people to order.

Will it be exactly like Pebble?

Yes. In almost every way. 

Aren’t you the guy who screwed this up last time?

Yes, the one and only. I think I’ve learned some valuable lessons.
