This machine has 11 UARTs on it, 4 of them are RS-422, the rest are normal 232.
I've got a couple 232 lines to other puters in this room, and a router. RS-422 goes down to the basement, and controls the machines down there, ethernet or not. There is a getty running on one, in case I get too drunk and smash the monitor.
I use the remainder for connecting to my microcontroller projects and programmers, etc. You can run it on *ancient* hardware, with no resources. It's incredibly useful for debugging microcontroller programs. Things that only have 128bytes of RAM, and a few k of program rom...
You can hook it up to a 40 year old TTY and it will work. You can haul a dumb terminal out from a cave and it will work. You can short every pin of the serial port together, leave it there for a decade, come back, and the bloody thing will still work.
I'm a rather miserable programmer, and serial is a bloody cakewalk to interface to. USB, on the other hand, isn't quite as simple. And it's a *standard*. Man I love things that are standardized.
I assume the ARM on the kindle has a serial port, or at the very least some GPIOs (so you can bitbang a serial port, or I2C). add a $2 MCU to convert a PS/2 keyboard to serial or I2C, and you're in business.
You could have the MCU in the keyboard, and use a 2.5mm headphone jack or so to plug the keyboard into the kindle.
Also, there are very small uart to bluetooth boards in the $15-20 range.. a pair of them work like a bridge... so: RS232 - bluetooth - RS232; bidir.
Slap one of those in your kindle, another in your keyboard w/mcu, and you're in business wirelessly.
And late model PIII's, (which were smoking the early P4's) only sucked 30-40W at the die. Netburst was just a big fail in general. A slow flamethrower.
Definitely... but the pumps should be harder to break open then, and someone should be checking them on a regular basis, to make sure they haven't been compromised.
Although my assumption is it's probably in house, so they should probably have a third party be doing the checkups, not the $5.50/hr clerk...
So.. 1 in the ECU, maybe a secondary to take care of flashing to make it unbrickable, that's two. 1 in the cruise control, ABS, radio, one or two for gauges and idiot lights... I guess the stuff with CAN on each device will have a micro, so the airbags get one (each?),
I'm having a hard time coming up with ten, and that's with liberally applying MCUs to each unit where one could do the job most likely...
I suppose you are right. But if the precedent of the DMCA wasn't set in the US, it would be easier for other countries to tell these agencies to sit and spin.
Did Americans not form the DMCA? Are they not pushing for this as well? It might not represent the American people's will, but it does represent the american industry's will, RIAA et al.

Not to mention that a _truly random_ shuffle could play the same song ten times in a row. Not likely, but on a long enough scale it will happen.

USB is a shade more of a pain in the ass to implement vs. a UART, and a lot of embedded stuff doesn't have a ton of resources to spare.
440BX was a brick shithouse of a chipset.
I've seen watch phones coming out of china for years now.
Normally the big firms innovate, and china copies, not vice versa.

maybe I'm missing something though?
He probably meant ionizing radiation. That covers x-rays too.
You need to take it to the next level - the tinfoil body suit is proven effective.
Stupid people? The same people that think microwaves are a mutagen?
People that play dress up aren't just nerds or geeks, they're dweebs.
And the whole thing probably fit in an 8k ROM or something?
that explains the speed :)
Now... you need a big enough ROM to stuff a modern OS in!
How many bytes was the OS on a TRS-80?
You can't really compare that...
And late model PIII's, (which were smoking the early P4's) only sucked 30-40W at the die. Netburst was just a big fail in general. A slow flamethrower.
And how much do you have to pay to make a modern x86 chip under licence?
The physical chips are definitely cheaper than anything x86 with similar speed.
Bit shift instead of multiply by powers of two
I'd think a decent compiler should do that automagically, no?
I always liked how Woody Guthrie put it in his song about "Pretty boy" Floyd (same era...)
"Some will rob you with a six-gun, and some with a fountain pen."
Man, I've got a huge shit-eater grin from "owl sauce" :-)

I have a seriously hard time believing that.

The second K&R (with ANSI stuff added) Is close to 300 pages, IIRC.
Correct, but there is plenty of snake related imagery with python. I always get a kick out of the IDE named "Boa Constructor".

I hope that at the very least a pathetic patchwork of internet, for the geeks, by the geeks, rises from the ashes.
Yeah, this is a problem. Most folks won't know this exists (if passed) until they receive a summons for DLing a MP3.
They need to add YRO to school curricula. ;)
