>I've never understood where 220 and 110 came from.

Those are the nominal or 'average' voltages. Nowhere has 100% consistent voltage supply. The UK goes from about 216v to 250v. If you were to plot the AC sine wave, the peaks would be nearer 330v RMS. But that variance is of no damn use to anyone who makes devices, or the consumers shopping for something compatible.

So a nominal is used, a nice easy number for everyone to read and go 'oh yeah, that works in my wall socket'.

These companies are just lost in some weird mind space at this point obsessed with all of the wrong things. "Shit we fucked up by not going chiplets" "Lets just test every single chip we have and find ones that can survive shoving 120v directly into them and sell them at a premium" "Amazing idea Bill now pass me that crack pipe you've been hogging it all day"

Yeah it was a bit scary, but I also am in a condo building with 12 other units in the same structure, so while around the doors and windows it was cold, in the interior of the house I believe the lowest it dipped that week was 54. Growing up, my dad used to not turn on the heat until it dipped below 58 in the house so I'm no stranger to wearing 2 pairs of pants, 2 long shirts, a hoodie, and 2 pairs of socks around the house.

Reply to Apple Reportedly Working on Touchscreen Macs, Including MacBook Pro by Avieshek

as an artist this was my only reason not to buy a macbook ever, i went for an ipad and its great BUT most of the software i use is not made for ipads, if this touchscreen can be used with the apple pencil im down to get one tbh. plus im in the minority that has carpal tunnel issues so touch is something i always use when available

My heat pump had a capacitor blow the night before we had those horrible freezing temps around Christmas hitting -40 wind chill, and -20F real temps. GF and I just stayed in our office with our gaming rigs both running software in the background using the GPU a 80-100% and that office stayed >70F the whole time. Living room had frost on the interior walls, which was neat!

The actual formula for calculating switching energy is approximately E=C * Vdd^2 * fs, where C is the load capacitance (larger the transistor higher the C), Vdd is the operating voltage and fs is the switching frequency.

This means that increasing the frequency affects the power consumption at the same rate as decreasing the physical size of the transistor lowers it.

Ofc making transistors smalles is extremely difficult at the moment, which means that the increase in switching frequency pretty much negates it. This combined with the increased transistor count pretty much guarantees that higher performance -> higher power consumption.
