I was about to post the same idea about a locality preserving pixel order. I was thinking about hilbert curves, never heard of z-curves. Would be nice to see if/how that affects the compression ratios. How surprising that a few simple

> Since landing in New South Wales, 4BBRW’s tracker has intermittently gone offline, which is common as birds rest because their feathers can cover the solar charging panel. So surprising you can run a GPS on a solar panel of about 1cm2

Yeah, same for me. I know my commute by bike will be 60-70 minutes, regardless of conditions. By car it is 25-90 minutes, depending on predictable and very unpredictable circumstances. If speed pedelecs work depends hugely on where you live

It is not the weight that is the problem (though the bike is heavy), it is that the fancy hub drive will not let the rear wheel spin freely when powered off. I have had to cycle home up to 20km with at about 18kmh, so slower than a lot of n

That was worst case, I ride in all weather conditions. 7 Bft headwind in winter would deplete the battery from full to 0 on my way home. Also it was difficult to get to max speed witb strong headwind, but 40kmh was always achievable

I had my share of controller issues, where the bike would give an error. Removing the battery a few times usually solved it, but somehow the magnetic connector is too sensitive. Worse is that it is really easy to improperly connect the char

I recently sold my ST2. I could get only 30-60km on a full (1kwh) battery at max speed (46 kmh). But then why would you go below max speed om a 7k bicycle? I got rid of it because it was also very expensive in maintenance, and because cycl

Yay, 13USD x team size to keep a simple architecture diagram up to date. Enterprises are rich, I get it, but tools like this should cost max 0.50USD/user/month. Or even better, someone should bundle several tens of these kind of t

This is because we don't price energy and raw materials as much as we value them. Putting a higher price on extracting natural resources will swiftly lead to less waste and less frivolous uses as they then become uneconomical. But as o

Better get on with it then. There is not a single solution, we must pursue each and every viable path. But in the meantime our religious leaders are still advocating against anti conception and against abortion. Reducing population growth w

I disagree: the climate crisis is the single most scariest thing that we have done to our planet. Other forms of mass environmental destruction (next to what you mentioned also mass animal extinction,rainforest destruction,PFAS) are all hor

I would much rather have an old fashioned dumb tv than a spying, adverising injecting, sluggish smart tv with crappy apps that never get updated. So the hedonic adjustment should definitely be negative.

The primary (only even) cause of the climate crisis is the fact that we have burnt and continue to burn a ton of carbon and emit it as CO2 in the atmosphere. And as most of the world functions with some form of capitalism, it makes a lot of

Technically feasible sure, but I thibk I used 1100m3 gas last year (would have to look it up teo be sure). So to invest 30000 euro to save 50% of that makes no economical sense. Only when the windows need replacement anyway I'll upgrad
