Föderation EN So 16.03.2025 08:38:42 “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.” — Rich Terrile, JPL scientist and member of the Voyager imaging team |
Föderation EN So 16.03.2025 09:25:28 @mrundkvist And it runs on a Raspberry Pico ARM microcontroller meant to turn on lights, read sensors and control toys. |
Föderation EN So 16.03.2025 13:15:21 @jannem @mrundkvist The microcontroller in the power brick of a MacBook is about as powerful as the original Macintosh https://www.righto.com/2015/11/macbook-charger-teardown-surprising.html?m=1 |

Föderation EN So 16.03.2025 14:03:30 @jannem @mrundkvist "brain the size of a planet, and here I am waiting *milliseconds* for the slow human to type a key, only to send it off to the computer doing actual work" |
Föderation EN So 16.03.2025 20:44:56 @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 |
Föderation EN So 16.03.2025 20:48:46 The only hardware upgrade I need for my old laptop is three replacement key caps: for the left hand CTRL and SHIFT keys and the letter "a". |
Föderation EN So 16.03.2025 14:35:30 @fl0und3r @jannem @mrundkvist @marcpalmer curious what a more modern power brick is like. The one used as an example is quite old at this point. |
Föderation EN So 16.03.2025 15:52:54 @ellenich @fl0und3r @jannem @mrundkvist @marcpalmer interestingly, it predates both their USB-C chargers and the switch to GaN. |
Föderation EN So 16.03.2025 12:25:17 @mrundkvist it's not in my pocket. I'm a woman, it doesn't fit in my pockets. You'd be hard pressed to get a coin in my pockets. |
Föderation EN So 16.03.2025 15:20:23 @Antiqueight @mrundkvist This right here is why I usually wear men’s jeans. |
Föderation EN So 16.03.2025 15:28:12 @melivia @mrundkvist i can't. They're the wrong shape entirely for me. |
Föderation EN So 16.03.2025 12:51:06 @mrundkvist @christineburns the phone is probably more computer than NASA had in *total* at the time of launch. |
Föderation EN So 16.03.2025 13:03:09 @StrangeNoises @mrundkvist @christineburns It's probably more computer than existed in the world. |

Föderation PT So 16.03.2025 18:13:57 The blinking clocks are also still here. |
Föderation PT So 16.03.2025 18:18:07 |
Föderation PT So 16.03.2025 19:15:47 @fzer0 @perikitapreta @mrundkvist And many of these appliances could easily get the current time (via NTP, radio clock, GPS,...) or do not really need a clock. |
Föderation EN So 16.03.2025 19:19:30 @Habrok42 @perikitapreta @mrundkvist Ya, but BigAppliance doesn't want that. And not so sound like a conspiracy theroist but who knows, maybe they are behind the yearly summer/winter time change too. |
Föderation PT So 16.03.2025 20:39:45 @Habrok42 @fzer0 @perikitapreta @mrundkvist Counter point: You need some sort of Internet connection for NTP, GPS |
Föderation PT So 16.03.2025 20:59:31 @partim @Habrok42 @perikitapreta @mrundkvist I see and acknowledge your facts and offer you this solution (Medien: 1) |
Föderation EN Mo 17.03.2025 00:47:31 @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. |
Föderation PT Mo 17.03.2025 00:23:17 @partim @fzer0 @perikitapreta @mrundkvist Valid points, but: |
Föderation · So 16.03.2025 22:08:38 nah… I turn power for those things of via complicated logic, Zigbee, HomeAssistant and half a ton electrical crap |
Föderation PT So 16.03.2025 19:44:24 @perikitapreta @mrundkvist Ein Heizelement ist kaputt gegangen und hat dabei den fi ausgelöst. Als der strom wieder da war, schien es erst als das der ganze ofen hin ist, aber es war nur die fehlende uhr |

Föderation EN So 16.03.2025 14:00:05 @mrundkvist Yeah no. 15% of the world's humanity actually has the luxury of possessing a car. |
Föderation EN So 16.03.2025 15:00:49 @otyugh @mrundkvist I can see the quote being said in a talk where everyone was indeed part of those 15%, but you still raise an important point |
Föderation EN So 16.03.2025 23:25:16 @dngrs @otyugh @mrundkvist but where was the talk so that everyone came by car? |
Föderation EN So 16.03.2025 14:01:11 @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*" |
Föderation EN So 16.03.2025 14:18:21 @mrundkvist "everyone" - ummm... (not only do i not have a car, i don't currently have a pocket) |
Föderation EN So 16.03.2025 17:18:02 "Powerful" is also doing a lot of work there. |
Föderation EN So 16.03.2025 16:09:39 @mrundkvist wasn't there a blogpost or something some years ago comparing the computing power of simple USB-chargers with the Apollo flight computer? 🤔 😂 |
Föderation · So 16.03.2025 17:15:26 @mrundkvist the e-marker chip in a usb-c cable is more powerful than early supercomputers (Medien: 1) |
Föderation EN So 16.03.2025 17:16:11 @mrundkvist key fob? There's no key fob in my pocket. Well, I'm blind so that makes it even more silly but I'm talking about the idea that the key fob is dropped in favor of using the phone as a key with that nifty new feature that our truck doesn't support. *whimper* |
Föderation EN So 16.03.2025 17:30:54 @mrundkvist The chip of a sim card is probably not far of either in terms of performance. |
Föderation EN So 16.03.2025 18:30:15 |
Föderation EN So 16.03.2025 19:43:34 @mrundkvist Talk about diminishing returns. |
Föderation EN So 16.03.2025 20:06:25 @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 https://www.top500.org/lists/top500/list/1995/06/ 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) |
Föderation EN So 16.03.2025 20:16:55 @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. |
Föderation EN So 16.03.2025 21:33:52 @dascandy @mrundkvist I'd love to see a plot of the lag (years) between performance of supercomputer/HPC systems (say top and bottom of top500) and the performance of a mobile phone. Is it opening or shrinking? |
Föderation EN So 16.03.2025 21:37:04 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. |
Föderation DE So 16.03.2025 20:10:20 @mrundkvist Not in my pocket, I haven't got a car. I hate cars and car culture, which is why I refuse to take driving lessons. |
Föderation EN So 16.03.2025 20:54:03 @mrundkvist I hate to disappoint you, but I only have two[1] handkerchiefs and a Swiss armyknife in my pockets. [1] As my father told me, one for yourself, and ond for your child. |
Föderation EN Mo 17.03.2025 01:07:52 @mrundkvist this is a paraphrase from 'the farthest', a fascinating pbs documentary that i hadn't seen. thank you for providing the spark for me to seek it out!

Föderation EN Mo 17.03.2025 01:51:31 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. |
