You mean, like a mainframe? Tech goes round in circles, more like.

Apparently, 51% attacks aren't enough to put off investors, as ETC had 3 of them in one month last year.

In this use case, hydrogen forms a fairly inefficient way of transferring energy from renewable sources to your car. As well as that, you have severe problems with distribution and storage - the pressures required are frankly terrifying as

Counterpoint: many atrocities have been made acceptable to the general population, in the name of "public health" (or at least, the greater public good). For me, "the greater good" does not over-ride personal critical an

I have worked hard to wean myself off the harmful effects of (mostly social) tech, and will do my utmost to pass these lessons on to my kids. My wife and I even have ideas like having a wifi-free house.

Yes, and we just threw away what little shared child-raising community we did have with Covid restrictions. Raising children isolated and alone is absolutely against every instinct, and (I think) incredibly bad for the long-term health and

I spent a while on this path - removing apps, hiding others, setting personal time limits or other restrictions on my phone usage. At each step on the way, all I learned is that I need to go further. Short of getting rid of your smartphone

Horses take a lot less energy and rare minerals to produce than Teslas, superchargers, and solar panels. Edit: You can also do multi-level agriculture, unlike solar panels https://en.wikipedia.org/wiki/Silvopasture

Horse and buggy is more sustainable than either ICE or EV. It's about the most efficient way to convert the power of the sun into forward movement!

How did it do that, while not just creating a regular second wave like most of the Western world?

by ppf 5y ago
Of course it didn't go away. So you are saying that Western countries, that took all the Covid precautions, had an early second wave. However, a densely populated country that took very few precautions didn't have a second wave, b

I enjoyed your little moment of US exceptionalism, assuming that I am in one of the dumber states, as well as the opening call to authority. Your references, in order: 1. This would be light on detail for a Medium blog post. "Reported

Would you rather buy a high-quality item, and factor in its resale value as part of your decision-making process, or buy a cheap item that will be thrown away when you're done with it? Do you think the purchasers of quality but second

I have two very young children, one of whom was born during 2020. I can tell you that raising kids that young, with both parents trying to WFH, and the lack of any support of any kind at all thanks to Covid restrictions, was a soul-crushing

You speak the truth. "Recycling" is mostly a sham, that we allow to soothe our consciences for living such an unsustainable lifesytle. A close friend of mine gained a Masters's degree in the subject, intending to work towards

You're assuming that it takes less than 13 cents / kg to extract that lithium.

Personally, my issue with EV battery (and electronics!) lifecycles is for precisely the opposite reason - the quarries and landfills in question are far far away from the places where EVs are actually used. All that most people will see is

It's tough. HN is the last of my social accounts. I'm really trying to limit it to once a day - you really don't miss anything, and it intrudes far less into your day.

In my opinion, the main Facebook site is now hard to get addicted to as a new user. I recently made a new account (having deleted my personal one years ago) for a local group, and found the site un-navigable and frustrating beyond belief. I

Indeed, which is why a careful examination needs to be made of the energy and resource cycles involved. It'll be interesting if we ever switch to an energy economy fuelled entirely by PV (or similar), and seeing how the energy economic
