“In everyone’s pocket right now is a computer far more powerful than the one we flew on Voyager. I don’t mean your cell phone — I mean the key fob that unlocks your car.”

This is a Macintosh (the original) emulator. It emulates the CPU, video hardware and floppy disk (partly) well enough that you run the original OS and applications on it.

And it runs on a Raspberry Pico ARM microcontroller meant to turn on lights, read sensors and control toys.

Same thing with the ARM controller sitting inside my keyboard. True, it does need to do both usb and Bluetooth; still, even the smallest, slowest Cortex m0 is really *way* overkill for the job.

@fl0und3r @jannem @mrundkvist my colleagues used to apply for faster and faster computers and I used to reply that if they wanted faster computing they should go and learn to type first. The slowest interface was brain to keyboard. They were two finger typists with RSI

@fzer0 @partim @Habrok42 @perikitapreta @mrundkvist the company I work for has resisted putting a RTC in our routers because the lithium battery requires its own set of disposal methods and needs to follow local regulations which are quite different around Europe, never mind world wide. Super caps wouldn't last long enough to be workable.

@partim @fzer0 @perikitapreta @mrundkvist Valid points, but:
- more and more devices want WiFi for their app
- GNSS signals can get into buildings good enough for the time (only 1 satellite needed for "good enough" time, not 4 for the position)
- there are transmitters like DCF-77 in many countries worldwide (on other frequencies)
- digital radio like DAB+ can easily transport a time signal
- devices like my CO2 monitor or thermometers do not need an always visible clock

@mrundkvist hang on, is the computer on Voyager more powerful than the Apollo guidance computer? It certainly has more RAM. It would make sense, as it was launched later and had to be autonomous while the APC had a human operator.

I ask because the version of this I heard was "the (second) computer in your pocket is more powerful than the one that *landed on the moon*"

@mrundkvist If you want a computer comparable to your cell phone, it's what in the movie Hackers was described as "Supercomputers, like you use to do physics or look for oil".

(source: Hackers is from sept 1995, most recent supercomputer list then was from top500.org/lists/top500/list/1 which lists the best one as doing ~200GFlop/s - which is about half of the current top mobile phone CPU. Alternatively take an Adreno 610 mobile gpu, which runs about 300GFLOP/s - which you'd get in an Oppo A53 from 5 years ago for about $200)

@dascandy Tech development has long since passed the stage of sufficient computing power for me to run my basic desktop applications under linux. It's been decades since I was interested in better performance in a laptop. It's like once engineers perfected cars that did 150 kmph, almost nobody was interested in faster ones anymore.

The main reason that I buy new phones isn't that I need more power: it's that Samsung pushes new bloated Android versions to it that I don't want because they make the phone slow without offering any useful new features.

Any USB optical mouse since about the turn of the century has at least a 12 MHz processor because it needs that to talk the USB protocol, which makes it faster than any computer in the world in 1977, and it has a second processor that tracks the image the mouse is looking at and figures out which way it's moving, and it's doubtful any computer in the world in 1977 could have done that in real-time.
