@foone basically instead of having10 and 1000you'd have10, 100, 1000, 10000, 100000the _minimum and maximum lengths_ of the pulses are determined by the amplifier parameters, right?but the duration of a single pulse isn't, it's just a continuously varying quantity. you can shove as much data as you want there, with lowering SNR

@foone then you "just" add ECC on top and voila, MLC floppy drive. ish

@foone I mangled the reality somewhat to fit it into the time and space I had here, but there's a giant-ass comment in the glasgow applet showing how all of it works

"that amount of energy is sufficient to charge 10 completely drained iPhone batteries"this is literally the electrical engineering equivalent of measuring things in football fields. what is it about americans and using real units

even if your goal is to make things comprehensible in comparison to mundane events, you could use "can bring to a boil X ml [or cups if you wish] of water"!water's heat capacity is 4200 J/kg/K, it's a very convenient number even if you are doing mental math

anyway, a single braking event as referenced above can bring 1 liter of water to a boil from room temperature, in what would be about a second of brakinghow's this for a relatable comparison?

@NullNowhere my point is exactly the latter one: while there's nothing inherent about joules that makes them intuitively graspable, the jump from "J" to "something well known" is shorter, especially in a global context

@NullNowhere and in particular kWh is used in basically only one context: billing for use of electrical grid (and by extension EVs, a big selling point is charging from the grid)everything else uses J, KJ, MJ, or one of the weird customary units if you're doing HVAC in NA

one of the stranger parts of living in the UK is how common the knowledge of the NATO phonetic alphabet is. everybody, from banks to landords, expects me to be able to spell my surname using itis it taught in schools or something?

it feels immensely weird to see civilians use it so extensively

for comparison: i came from a country significantly more militarized than (modern-day) UK and i didn't even know what the phonetic alphabet in use was like until i googled it just now

catherine picks an IP camera, an adventure in 3 steps:1. download firmware updates for 174 cameras2. extract a device tree from each of them3. intersect the chipset list with https://openipc.org/supported-hardware/featured(... how else would you do it?)

@grimalkina a CO2 sensor once beeped at me wrong and i turned it into a pile of shredded plastic there and thenin retrospect, i think it was probably an overall increase in quality of life even if i definitely open the windows less now

if it was available for "$50" (excluding tariffs, duties, and taxes), would you buy a device with a small FPGA and something "fun" (VGA-resolution screen, buttons, etc) which would have an associated Amaranth tutorial, as well as the ability to simulate the device (at less than real time) for debugging?

maybe what Amaranth needs is a "starter FPGA project", something fun you can buy cheaply and mess around with
