[discuss] Errantry, jrr Tolkien first mumble rapper

I was just introduced to errantry by jrr Tolkien. This thing is fire.

There's a polygon video by Brian David Gilbert where he explains the triplet flow used by a lot of mumble rappers, and then he goes on to rap the three -syllable Pokemon names. Great vid and a great rap. I mention it because the triplet part has always stuck in my head and gotten into my own writing. It was interesting to find triplets in an old jrr Tolkien poem.

Anyway, was jrr Tolkien the first mumble rapper? Ant Any other good old poems that use triplets?

Impedance, floating

What's the difference between impedance and when a pin on a microchip is floating?

I get the basics of impedance. I'm capacitive impedance it's a build up of charge. Like air in a balloon. In resistive impedance it's a build up of the magnetic field, like a flywheel.

A floating pin isn't connected to anything reference voltage so it can fluctuate with surrounding interference or whatever.

Why do some ICs have tri state, low, high, and high impedance? Isn't high impedance the same thing as floating?

If it is high impedance that means it had to be connected to something, right? Don't Some kind of big capacitor or inductor in the chip?

GPL + butt hole?

License stuff came up the other day. Got me wondering.

Could I use something like the mit or GPL license, but add a requirement that anyone that uses the software had to send me a pic of their butthole?

What is the use case for this GPL + bhole license?

Memes mostly. It world also need to have an age of majority clause.

Then if the library actually gets picked up somewhere it would be a good extortion tactic.

Simultaneous joystick 3-axis protocol

Working on a joystick. Seems like any protocol I use to read from peripherals is going to be bottlenecked by having just one input. My microcontroller might have multiple ADCs, but there's just one processor stepping through them. Same for spi, or i2c, or uart. There's really only ever one sensor reporting back its data at a time.

I know this might not matter for measurement resolution. Especially if you're polling at like 115k serial or something, but...

That's 8 bits per axis, and three axis. Now that's at least 34 bits. To sample each axis we're down to only 4.5k samples per second. Plus whatever other cycles the controller has to handle... even if I spent half that time doing microcontrolle cycles at like 2k we're probably still well with the best star craft apms or whatever. I'd still like to find some way to really over engineer this thing.

I read a little about tdm, but that's out of my league and I don't know if you could even have 3 simultaneously signals that way

I'm thinking a microcontroller for each axis, and a usb port for each of them. So it appears like 3 different controllers to the computer. The user would just have to map the axis from the 3 controllers into 1 in their game software. I assume the steam remapping could do this.

Is it just going to get smashed back into one thread in the computer's usb hub anyway?

Any other suggestions?

Too horny?

I just had to turn down a prancing Wyll. I tried to let him down easy, but he wasn't getting the hint.

Is this what it's like to be a woman? Dudes come prancing up to you out of nowhere like it's their best move, then get bitchy when you don't drop your pants for a two step?

I know I risk summoning the worst of the Internet with this question. I'm still curious if anyone's experienced similar in the game. Maybe I'm way off thinking there's some empathy lessons in here. It's obviously not the message of the game, but maybe one of the messages.
