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 really wanted to like the Playdate but it's such an unbelievably overpriced and underspecced toy. But the crank, which really looked like a gimmick, is oddly quite nice to have and I wish my kids' Retro Arcade had one.

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 it's better than hiring another human" doesn't work out. The human doesn't stop burning fuels when not in use: any LLM usage is additional energy that needs to be generated while staying within CO2 budgets

This isn’t scroll hijacking You can scroll normally, with all your favorite keys, or go super fast to the bottom It’s just scroll animations. Bad ones, admittedly.

Just use your page_up/page_down keys, and you can skip all the stupid/excessive scrolling requirements.

how do i press these buttons on my android phone?

When I was at Peloton a long time ago, someone proposed an April Fools’ joke where we could announce a dynamo add-on that would let you power your house from your bike.

The math isn’t as bad as you might think: 200Wh (about a 60 min, somewhat intense ride) seems to be about 20 minutes for a H/B100. Still 3x, but not bad at all!

I remember the idea being dismissed quickly because people would likely actually want it.

As a bit of an aside, I really like the idea of trying to design things with the constraint of it having to be able to run off a hand-crank. I feel like it is not only an interesting engineering challenge but one that might lead to a more efficient and sustainable framing.

Or we could... hear me out... build more power plants. The de-growth stuff is pretty evil when you take it to it's logical conclusion of population control.

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

For more reference how insane 700W is, the average FTP of a world tour pro road cyclist (i.e., Tour de France) is ~350-420W/6-7W/kg. FTP (Functional Threshold Power) being the avg you can sustain for an hour without fatiguing. My own is ~250W @ 3.12W/kg. I can't even hit 700W yet, let alone for over a minute. My 5 second power is ~640W. Crazy numbers.

A trained powerlifter probably exerts a few kW on a heavy lift, but only for a second or two.

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'…

As an average male who is ~175lbs and untrained at cycling, this is hugely validating for my terrible idea; 140 watts is the max charging speed for 16" M5 MacBooks. I can finally stop thinking for myself and have my computer do it all for me, powered by my big beefy legs.

140 watts is the FTP. That means you can do it for an hour, and it will be an extremely exhausting hour and you will want at least two days of rest to recover from this workout before doing it again.

If you are not chasing watts, it’s much more sustainable to do 70 watts for two hours. You can probably do this every day.

Not sure it's possible to say this without being pithy, but haven't there been stories told, perhaps TV episodes and films made, regarding the concept of using human bodies to generate power in support of machine intelligence? Seems a little on the nose to me, but I guess some days it's hard to tell what's a gag and what's a legit pitch.

Well, the Matrix did this. Badly. "Machines who have developed nuclear power are using human bodies as batteries"-level badly.

Well, the original script said they used humans for their brainpower (computation)
