I regularly notice bugs when using iOS Mail; one that springs to mind would display one email's body with the header info from another email, it seems to have recently been fixed but was easily reproducible for weeks if not months.
Microchip: please hire me to work on the Rust HAL for your ATSAM chips, which I currently volunteer the odd hour or two to help maintain. Between Rust bringing robust modular software in to embedded, and companies like Adafruit pumping out ATSAM boards, there's huge potential in this space.
There was a deep technical reason for it, too. I suspect I'm one of the very few living people that know what it was., so I'll share it with HN so the knowledge doesn't die :-)
A relatively early type of mechanical telephone exchange was the rotary exchange [0]. The pulses from the phone cause a clutch to connect the rotary driver in the exchange which then moved the switching stuff around (details can probably be inferred from the linked article). One of the issues with the rotary exchange is the pads of the clutch wear, leading to unreliable connections. Aotearoa/NZ had an existing number plan when they decided to install rotary exchanges. Some bright spark knew of the wear issue, and calculated that, given the existing number plan, if they had the 1 position on the dial giving 9 pulses (etc.) then the overall wear on the pads would be much lower and so the maintenance requirement would be less. And that's where it started.
And another fun fact. I believe Norway chose the same configuration for their rotary phones. I'm not sure if it was for the same reason, though.
Thanks for this. I'm a kiwi and wondered why we were different.
When friends started bringing pushbutton / cordless phones across from Australia, I was able to convert them to NZ numbering by reversing a few wires on the keyboard matrix. These generated pulses long before DTMF.
The driver supports alternate keycode mappings specifically for that reason, but before reading your comment I was unaware of the motivation behind reversing the pulse order. Thanks!
There are techniques for "stack"ing transistors so that the individual swtiching devices see potentials that are within spec and much lower than the voltage switched by the overall circuit.
"The 8th blade sends an electronic pulse to the center of the brain, which destroys the part of the brain responsible for hair growth and 4 other nonessential functions"
Usually the HAL is between the main firmware and the PAC, so whether the PAC methods are marked as unsafe could almost be considered an implementation detail.
But yes, there has been a lot of discussion around how to handle DMA peripherals - the embedded_dma crate offers some abstractions that I've found handy.
Whoops, yes you're correct. Serves me right for looking at some SEO spam link!
Main point was that bronze is much more common in marine applications than brass - I wouldn't be surprised to learn there's been an error upstream as well.
It was a stupid riff on the title. But, the Arkansas River does start in Colorado, and so some amount of Colorado's snowpack does wind up in Arkansas' river.
