My partner just got a rowing machine that offered "watts" as a unit of how hard you're going (like "calories" or "mph") and got me wondering if they made rowing machines that could slowly charge a battery, and how much I'd need to row to power one of them fancy newfangled M5 Max MacBooks answering prompts. All that to say, CrankGPT, I am your target demographic and if you don't respond to my request for a demo I'll b…

The "Low Tech Magazine" has a guide to building a DIY bike generator https://solar.lowtechmagazine.com/2022/03/how-to-build-a-pra...

Unfortunately even with the bike it seems like you really need to find one machine that can be repurposed, a rowing machine seems a bit of a stretch.

Playdate (the came console) is amazing for this! I was really bored once and built a Claude Code remote control for Playdate. Voice recognition was done via parrot + handy.computer Basically: different key combos were tied to different actions, e.g. \ - hold A to speak - move the crank slowly to navigate - crank super fast to send the prompt Eventually this became a universal remote control for the computers in my ho…

I have one too and it never occurred to me to use it for anything other than games. Would be interested in seeing how you did it!

OK, I'll clean it up and post it in a few days

The webpage linked is an example of everything I wish people would stop doing in web design. Fortunately, at the bottom there is a link to the "technical documentation" ( https://squeezlabs.github.io/handcrank/ ) which is vastly improved (aside from being light-mode-only and linked from a dark-mode-only marketing page). It also gives me much more interesting information (specifically: models that can apparently run a…

Yeah this is a better link https://squeezlabs.github.io/handcrank/

I can do high level thinking for around 6 hours with just two scrambled eggs and a cup of coffee. What I need is something to prevent me from context drift. /starts googling how many scrambled eggs are equivalent to the energy consumed by a data center. Google how many chickens are in the world.../

Consider that you can do this as a working day because someone else is plowing the fields that grow your food, probably burning stored energy in fuels for the process We're sadly not that efficient. The 150kcal/6h=600kcal/day you've mentioned aren't enough, and it takes more than 600kcal to create 600kcal plus transportation into your home Besides, we won't stop existing, so any math about "chatgpt uses X kW and so i…

> and it takes more than 600kcal to create 600kcal plus transportation into your home

This is not a strong argument or at least a different area of discussion. Because you can say exactly the same for the electricity: you need more than the power. You need the coal+transportation, or power plant, or solar panels ...

I'm pretty sure humans are much more energy efficient ... for certain tasks ;)

I agree this type of web design sucks. It's been common for more than a decade - I remember Apple getting criticized for using this on the product page for the old "trash can" Mac Pro in 2013, and it was already widely used back then.

However, it seems pretty clear to me they did this in service of a joke - you have to "crank" your scroll wheel to get to the content, just like you have to crank this device. I think it's funny...

For reference, this is what 700W cycling looks like: https://www.youtube.com/watch?v=S4O5voOCqAQ

I took several biomechanics classes as electives back in my undergrad, and in one assignment I remember comparing the energy outputs between the human and robot equivalents of different tasks, whether or not the robot was humanoid in how it was designed. The most impressive think that stuck with me is that humans are incredibly efficient , from an energy perspective, in anything we do, compared to machines. Every tim…

A fairly untrained cyclist is usually able to maintain 200W, so yes this is definitely possible

An untrained cyclist is not able to maintain 200 watts. For an average untrained male cyclist who is 175lb, they should be able to maintain 1.5-2 w/kg over an hour, or 120-160watts. A beginner cyclist who's been cycling recreationally over over a year should be able to attain 2-2.5w/kg which is 160-200 watts. A recreational cyclist who's be training for several years should be able to maintain 200 watts. Trust me, I'…

Just one more follow up and I'll be done, promise. The average power output (FTP) of someone on zwift, a indoor cycling game, is a whooping 185 watts.

Could this maybe be fixed by arranging the files on the filesystem in the order they're read? Or maybe importing the Python modules from a zip file (with no compression) would be faster, if that makes it easier to store them in the required order?

I seem to remember Windows having some sort of feature like that, automatically rearraging the data on disk in the order it's read when booting the system.

This website is satire, right?

P.S. I agree with you 100%
