the chinese fixed my posture for half a kinesis

a keyboard is one solid rectangle because a typewriter had to be one solid rectangle in 1874, and you have been holding your wrists at an angle designed for a machine full of METAL LEVERS ever since. nobody decided this was good for you. nobody decided anything. it's just inertia wearing the costume of ergonomics.

i bought a split keyboard and now i cannot go back, and i need to tell you why before your tendons file a complaint.

your keyboard is one bone and it's breaking you

pull your hands up in front of you, relaxed, like you're about to type. look at them. your forearms come in at an angle, your thumbs point UP, your wrists are neutral. that's the resting posture of a human primate. now put them on a normal keyboard. wrists rotate flat (pronation), hands squeeze together toward the middle (ulnar deviation), and you hold that all day, every day, for a career. it's a stress position. we gave ourselves a stress position and called it an office.

a split keyboard is just two halves you can shove apart and tent up so your hands land where they already wanted to be. it is stupid how simple it is. you separate the two piles of keys and suddenly your body isn't fighting the furniture.

home row is based, actually

here's the part that nobody warns you about: a split keyboard makes you type CORRECTLY whether you like it or not. there is no crossing the divide. your left hand physically cannot go reach a y on the right island like it's been cheating its whole life. so you learn the home row for real. left hand owns the left, right hand owns the right, and the split ENFORCES the border like a customs agent.

and no, i'm not gonna sit here and tell you i type faster now, because i don't. i got this thing for my birthday, i've got maybe three hours on it total, and today (friday, full swap, no takebacks) i am SLOWER than i was on the slab. every muscle memory i own is currently useless. but every finger already knows it has to stay on its home keys, my hands have basically stopped roaming, and even crawling at half speed it feels like the keyboard finally admitted i have two separate hands attached to two separate arms. the speed comes back. the posture is here now.

and i want to be honest about how deep the brain damage goes: i STILL try to grab the y with my left hand. right now, writing this, i reached for it with the wrong hand THREE TIMES IN A ROW like a raccoon pawing at a locked door lmao. fifteen years of my left index freelancing across the midline of the keyboard, and the split just sits there going "no." i physically CANNOT do it anymore. the divide doesn't care about your bad habits, it just amputates them.

your thumbs were doing nothing and you didn't notice

look down at a normal keyboard. what do your thumbs actually do? one of them taps spacebar. the other one is UNEMPLOYED. two of your strongest fingers, the opposable ones that supposedly separate us from the other primates, and a unibody slab hires exactly one of them, part time, for one job.

a kinesis-style keywell has thumb CLUSTERS. real keys, a whole little committee of them, sitting right under each thumb. mine do enter, backspace, meta, ctrl, space, layer shifts, whatever i decide to map. so now my thumbs have a JOB instead of loitering, and my pinkies stop getting reamed reaching for enter and backspace the way they used to. the work spreads out across the whole hand instead of dumping on the four fingers and one overworked thumb. it turns out i had eight fingers and two thumbs the entire time and my keyboard was only letting me use about six of them.

the six hundred dollar problem

the catch is the good ones cost like a used car payment. a kinesis advantage is SIX HUNDRED DOLLARS. an ergodox, a moonlander, a glove80, all of them are somewhere between "ouch" and "are you insane." ergonomics has this gross tax where the thing that stops you getting injured is priced like a luxury good, as if not destroying your wrists is a premium subscription.

and look, i'm in the third world. six hundred us dollars for a KEYBOARD is not a purchase i get to make, no matter how much my wrists are begging. i'd love to. i would genuinely love to walk in and slap down kinesis money and never think about it again. but let me put six hundred dollars in real terms for you: stretched right, that's three months of FOOD. not a keyboard. dinner, for a quarter of a year. that's the actual exchange rate, and reality is a bitch lol. so the $600 board isn't a product i weighed and passed on, it's a product that was never on the table for me or for most of the planet.

so obviously i went to the chinese.

shenzhen doesn't respect your patents and god bless them for it

i got a kinesis advantage CLONE. keywell, thumb clusters, split down the middle, the whole scooped-out bowl, minus the fancy metal because the entire thing is 3D PRINTED. the keyboard was two hundred bucks, and with shipping and taxes it landed around three hundred, which is HALF a kinesis, and it got here fast as hell too. is the plastic as nice as the OG? no. do i care? my hands are on the KEYS, not filing their nails on the case.

and the lad i bought it from just... threw stuff in. a bag STUFFED with keycaps, gorgeous ones, way more than a single board needs, for free. plus a dinky little screen gadget that echoes back whatever letter i just typed, completely pointless, absolutely delightful, i love it. try getting a free bag of keycaps out of a company that charges six hundred dollars for the same idea. the clone economy runs on goodwill and volume and the brand runs on making you feel lucky to be allowed to pay. it's also full QMK. that took me a minute to learn, not gonna lie, the whole layers-and-macros mental model is a wall the first time you sit down with it. now it's a GODSEND. i can make the hardware do whatever the fuck i want, remap every key, stack layers, bury symbols under my thumbs, and nobody gets a vote but me. it's the Stallman-and-the-printer thing: the moment a piece of hardware decides what you're allowed to do with it, you should get to crack it open and tell it to shut up. my keyboard takes orders from ME.

and this is the part the brand people never say out loud: the reason shenzhen can sell you an ergonomic keywell split for half the price is that the "innovation" you're paying $600 for is a THIRTY YEAR OLD IDEA about where hands go. the moat was never the engineering. the moat was the price tag and a patent and the vibe that ergonomics is exotic. the clone economy just walked over, turned the vibe off, and threw in hotswap for the disrespect. based.

and honestly the chinese have been quietly keeping me typing for years. the board this one replaced was a royal kludge 61, also chinese, a little 60% unibody that served me faithfully for several years before i went and betrayed it for a keywell. it's in storage now, exiled, guilty of nothing except being one solid rectangle. maybe i'll mod it someday and hand it down to a buddy, maybe it just sits in the drawer as a monument to the before times, who knows. but half my desk history is shenzhen doing more with less, and the split is just the loudest version of it.

it's so good going back HURTS

i had to grab my old unibody an hour ago to fix something on my other machine and my hands recoiled like i'd asked them to hold a dead fish. wrists snapped back to pronated, thumbs clenched, the whole miserable little clamp. i lasted maybe two minutes. i have been RUINED for normal keyboards and it took ONE AFTERNOON. my back sits up straight now because the two halves let my shoulders open instead of rolling my whole torso forward over a slab. i didn't even do that on purpose, the geometry just doesn't let me hunch anymore.

and this clone has a built-in hand rest along the bottom, so my palms have somewhere to LIVE instead of hovering or mashing into the desk edge. wrists stay flat and neutral, thumbs fall straight onto their cluster, and my hands just sort of park there between keystrokes. three hours in and the thing that's already undeniable isn't the speed, it's that nothing HURTS. i can type for a block of hours and my wrists aren't quietly filing a grievance the whole time.

what DOES hurt, and it isn't even really the keyboard's fault, is my back. it hurts like HELL. you know why? because the unibody had me sitting like absolute shit. the split more or less forces me into a HUMAN posture whether i like it or not.

the actual reason

okay. here's the thing under the jokes, and i'm only saying it once because you need to hear it and then we can go back to laughing.

RSI is not a meme. repetitive strain injury is the thing that quietly ends the careers of people who type for a living, and we type for a living. it doesn't announce itself. it's a little tingle, then a little ache, then one morning you can't hold a coffee cup, then you're the thirty-eight year old who can't work a full day and nobody warned you because the injury was BORING and slow and didn't bleed. your hands are the tool. they are the ONLY tool. a carpenter who sands his own fingers off is out of a job, and so are you, except your fingers took fifteen years to go and you didn't notice the sander was on.

a split keyboard is three hundred bucks of insurance against becoming that guy, half of what the brand wants, and the clone throws in hotswap for free. it's not about typing speed or looking cool at the cafe with your weird alien keyboard, it's about still being able to do this at fifty.

so buy the clone. tent it up. learn the home row like you should have twenty years ago. your wrists are the one piece of hardware you can't RMA :)

UNIBODY KEYBOARDS ARE A PSYOP!!!

ok now the part where it's a weapon

here's the thing i buried under all that stallman worship: full QMK will type ANYTHING. a macro is just a key that, when pressed, emits a string of keystrokes into the host as fast as the usb hid spec allows. that's the whole feature. and if that description is ringing a bell it's because it is LITERALLY a rubber ducky. a programmable keyboard is a BadUSB device you paid two hundred bucks for and then rested your palms on.

// qmk, roughly. one keypress and the "keyboard" types this itself.
case MY_MACRO:
    if (record->event.pressed) {
        SEND_STRING(SS_LGUI("r"));      // win+r, run dialog
        SEND_STRING("powershell\n");    // and we're already inside
    }
    return false;

four lines, and that's the BORING version straight out of the docs. the OS never asks a keyboard for ID. there is no permission prompt for "is a human actually pressing these keys." the keyboard is the most TRUSTED device on your desk and nobody has ever threat-modeled it, because it's furniture. it's been furniture since 1874, remember?

now scroll back up. i plugged in a keyboard a stranger in shenzhen shipped me and i was so busy cooing over the FREE BAG OF KEYCAPS that it never once occurred to me to ask what the firmware types when i'm not looking. mine's clean, i flashed it myself. the point is the gap between "lovely birthday gift" and "HID implant" is a single firmware image, and you cannot see a firmware image with your eyes.

so obviously i went and did the first half already. the stock firmware was proprietary, so i REVERSED it, and out of the wreckage crawled the glamorous anti's AN360, my own firmware running on the clone's guts. it even introduces itself in lsusb, because i wrote my name straight into the usb descriptor:

Bus 001 Device 074: ID 1322:5772 anti's AN360

that is the exact opposite of stealthy, i KNOW. the quiet build is one string away. but i wanted to watch my own device stand up and say hi first :)

what's left is the language. hand-writing QMK macros in c for every payload is misery, so the next thing i build is qmkscript, a little DSL that compiles down to firmware. ducky script's meaner cousin. and i'm writing it with flex and bison, a lexer and a parser generator older than the usb port they're going to attack, partly because a real grammar is the correct tool for this and partly because i hate myself and have wanted an excuse to learn them for months :) build the compiler, learn two fossilized unix tools, ship both. that drops with the follow-up.

what i still haven't fully solved is delivery: how a real payload slips past edr when it arrives dressed as nothing but innocent keystrokes, how you stage it, how it survives being typed instead of dropped. but i'll find a way. as previous posts say: "the bypass is there, you just have to find it."

and the reason this one actually matters, not as a party trick: it isn't a usb stick in a parking lot that a trained employee knows to leave alone. it's a KEYBOARD. it's the one peripheral every human on earth plugs in without a flicker of thought. borrow one, gift one, quietly swap the one on a coworker's desk while they're at lunch, and it types out the entire killchain before they've finished sitting down. no file on disk, no download, nothing for the scanner to find, because from the machine's point of view a person just typed really fast. the trust IS the vulnerability, and it was installed before any of us were born.

I AM THE WORLD THAT HIDES THE UNIVERSAL SECRET OF ALL TIME
