thank you everyone for putting in the time to listen to me and understand me
i feel so misunderstood and unwanted by the largest part of society
i find it hard to say nice things to myself, so when you here do, it gives me a little more strength to continue subsisting in this existential wasteland
You have to choose the right one with the right features, then put it in to the special ultra-low-power modes, often fully asleep with wake-on-input or only the watchdog timer running. The trick to low power computing is largely to not compute as much as possible.
@vidak
I mean, the general concept is, you just set up your interrupts to listen for the input/timer event/whatever you want to wake up the computer, do whatever's required to sleep your peripheral hardware (other than external timers that will send the interrupt or extra RAM or whatever you need to keep alive), and then put the microcontroller to sleep.
The problem is 1) that doesn't help with reducing power when running, and 2) you have to choose peripherals to ensure that they all can be put to sleep (or at least, you can set up a transistor to cut power to them or something). The real hard part is designing it to be reasonably low power when running though, especially for things with any human output devices which inherently tend to just eat power (even e-ink and to a lesser extent memory LCDs absolutely hog power when refreshing, it's just offset by them not using any power when not refreshing)
So I implemented grep in ed scripts with a minimal bash shim. Find it at https://aartaka.me/scripts/grep.sh
i know you can run a processor on a coin battery for weeks/months, look at tamagotchis/digimons.
iirc, many microcontrollers can be put into special modes that draw very little current from their power source. they may be running at a clock speed in the region of tens of kilohertz, but that is no issue for me.
my problem is i just can't find much practical instruction online about how to do such designs 'homebrew'. usually people just point me to a specific microcontroller datasheet, and that's it.
maybe my next deep dive will be how to build a lil puter that runs on a current draw that is ultra-low.
the permacomputer project has more followers than i do
there was a lot of activity on the profile last night
i got some scathing criticisms of the permacomputer off-fedi the day before that really affected me. i think i am far too sensitive for my own good.
the attention the permacomputer idea is getting makes me feel a little bittersweet about the hobby project--i feel good about the huge amount of support it is getting, but i wonder whether the whole project is misguided and impractical.
should it be focused on a speculative, and as yet imaginary societal collapse, or should the project instead change to instead promote ecological and sustainable computing?
i think the project needs to change focus.

OR, and hear me out on this, we can all just agree that it's high-time to migrate to Plan 9 and systems built like it.
Adding complexity on top of complexity will make things increasingly insecure, not more.
Your $12-15 payment every month to Spotify disappears into a blackhole and is noticed and appreciated by exactly NO ONE. By contrast, you could spend that same amount today at Bandcamp, OWN three albums because of it, AND make the day of each of those artists.
Seriously, a $5 sale can change a life.
@permacomputer Can I suggest dropping the "70s" from the "What is"? (As a Board member of Permaculture Australia, very much 2020s and looking forward).
Libreboot 20241206 released!
Free/opensource firmware, replacing proprietary BIOS/UEFI.
https://libreboot.org/news/libreboot20241206.html
Highlights:
* ThinkPad T480 and T480S support
* Dell OptiPlex 3050 Micro bug fixes e.g. PWM fan controls work now
* U-Boot payload on x86 machines, providing UEFI-based booting; not tested on all boards yet, so chainloaded from SeaBIOS. Use a "seauboot" ROM; ESC menu in SeaBIOS can bypass U-Boot
* Mate Kukri rewrote deguard. It can disable Intel Boot Guard on any MEv11 machine now!

I've spent nearly 48 hours wondering about the UHC CEO attack and hearing all of the vitriol directed his way. And now I am hearing that Blue Cross Blue Shield has repealed its decision to charge patients extra for anaesthesia if their surgery takes too long, as if the attack had an effect.
But, yet, the political right somehow lands the message in the United States that the left wants to "take away your private healthcare." They. Land. That. Message. All. Of. The. Time.
How?
It is obvious now that USian healthcare firms and the rent-seekers who get rich off them are among the most reviled people in the country. How does this message keep landing? It is quite obvious that next to nobody likes their private insurance.

i need to listen to my own advice to others
fuck the haters, people who try and bring you down are spiteful
I see shit like this happening, and I can't help but shake my fists and gnash my teeth in frustration. https://hachyderm.io/@robpike/113602589372259355
And, Rob isn't exactly what I'd call a complete newb at this computer touching thing, either.
This is why I desperately want to have a truly personal operating system that runs on my truly personal computer.
VM/OS is my latest attempt at making my dreams a reality. But, I'm only one person. It would sure be nice if, someday, I could get some help with it.
Day 5 of the #DecemberAdventure and, honestly, I thought I was gonna chill this evening and not do any code, but then my 8 year old and I pulled together the bones of a little gravity platformer game!

Absolutely in awe - and extremely envious - of this successful project to build a functional replica of Harmut Esslinger's 1984 FlatMac tablet prototype - which was only ever a non-functional design prototype, never launched.
I want one.
