@drmaddkap who hurt you?
@book The same person who decided to put “shot of adrenaline through the chest into the heart” as part of a movie.
That’s not life saving. That’s instant death. Rupture the heart wall, quick bleed out.

How defibrillators work in movies:
“There’s no pulse. CLEAR! *zap* Oh thank God, he’s coming back.”
How defibrillators work in real life:
“He’s asystole. Call it. Time of death 5:23PM”
@drmaddkap CPR in films: clean, pretty, reliable
CPR in real life: you probably just broke a rib, you're tired by the second set, and there's still no/weak pulse. Oh and that snoring? Yeah, that's agonal breathing. They're not back yet. Keep going.

And the outcomes are terrible. No one walks out of the hospital IF they survive CPR.
I hate medical procedurals' clean endings.

@drmaddkap @book
Sometimes I give myself a shot of adrenaline through the chest just to feel something -

@drmaddkap @book See also : Gunshot wounds in movies. Sure, that little dressing will fix you up nicely. Of course you'll be able to run, jump and fight with no issues what so ever :D

@BenHM3 @eviljackcarver @drmaddkap so while the odds are terrible *I* did!
(Out of hospital cardiac arrest, CPR & defib by some Marines (randomly). Heart bypass. Walked (very slowly) out of the hospital three and a half weeks later. Still alive & kicking 7 years on)

@BenHM3 @eviljackcarver @drmaddkap Some survive, but not all that many. I do remember admitting a patient to ITU from the operating theatre recovery after a successful restart of his heart, thinking it would be doom and gloom in the morning. When I arrived, he was just getting back from the shower.

@drmaddkap Don't defibrilators do a lot fancier stuff than just that?
> “He’s asystole. Call it. Time of death 5:23PM”
"My Robot Buddy the Defibrillator" or something. -

I injected adrenaline once, thanks Hunter S. Thompson. It floored me. I never did it again.

@eviljackcarver I figure there's good reason why, in actual first aid classes covering CPR, the instructor will reiterate "keep doing CPR until the ambulance arrives and trained medics take over".

@drmaddkap With all due respect, I say this as someone who spent twenty minutes dead and is only alive due to CPR and a defibrillator?
Bullshit.

@digitalraven @drmaddkap You were insanely lucky! The survival rate for CPR/defib is not great: around 7-8% of patients on whom rescus is attempted survive to see hospital discharge.
It's still worth doing, but most media portrayals are very misleading.

@cstross @drmaddkap I'm aware of how lucky I am, but 7-8% is way better than 0% and I'd rather people try than assume it won't ever work.

@drmaddkap Does sticking nails through one’s hand stave off death like in Bladerunner?

@andrewg at this point I genuinely think Mozilla's culture is broken beyond repair and this is very sad.

When I lived in #Ireland, I saw oceanic tides for the first time and it was a shock.
The Mediterranean sea wobbles by a few meters but the ocean just goes away!sleeping on wet sand
a skiff awaits
the waves return

Nintendo’s Family BASIC Keyboard Gets USB Upgrade
America knew it as the Nintendo Entertainment System, but in Japan, it was the Family Computer (Famicom). It was more than just a home console—it was intended to actually do a whole lot more. All you had to do was plug in the keyboard and chuck in the right Family BASIC cartridge, and you had a computer hooked up to your TV! [Lucas Leadbetter] came across an old Family BASIC keyboard recently, and set about making it more useful in our modern age with a simple USB upgrade.
[Lucas] started with research, and soon found plenty of schematics and details on the keyboard on the NESdev wiki page. Hunting further turned up a video from [Circuit Rewind], who demonstrated how to hook up the keyboard to a Raspberry Pi Pico, including how to interface with the onboard chips to scan the keys. These resources told [Lucas] enough to get going—and that it should be as simple as wiring some custom hardware up to the internal keyboard matrix connector to get it speaking to USB.
[Lucas] went a slightly different path to [Circuit Rewind], implementing the popular QMK firmware to suit the Family Basic keyboard on an Adafruit KB2040. The Adafruit part is basically an RP2040 microcontroller slapped onto a tiny PCB in a form factor that’s ideal for making custom keyboards. [Lucas] was able to reimplement the scanning logic that [Circuit Rewind] had reverse engineered previously, and had the keyboard up and running in short order with all the usability benefits of the QMK firmware. Files are on Github for those eager to recreate the work.
As far as usability goes, [Lucas] notes that the Family BASIC keyboard is more of a conversation piece than a daily driver, thanks to its rather poor feel. Duly noted. We’ve explored how software development is done in Family BASIC before, too. Video after the break.
