A traditional bicycle chain drive is something around 98% efficient - particularly if you're using internally geared hubs or a single speed with the chain line perfectly straight. What's a typical consumer alternator efficiency? Maybe 85%? And then a few steps for losses in the charging circuit and then again at the motor.
Not even napkin math, but ballpark I would think you're looking at having to pedal about 20-25% harder to accelerate the same rate compared to a chain, with no supplemental energy directed towards charging the battery (though I would assume al the energy goes through the power management system anyways).
However you get some gain in that you don't have to select a gear ratio, and that the electric motor provides torque efficiently at any rpm you can realistically expect on a bicycle. If it has an adaptive resistance level it will probably be more work (energy) but for many non-cyclists feel much more intuitive and simple
The alternative to a huge bubble is that it's ripple effects of inflation. All assets go up, RE, equities, btc, and gold/PMs because there's simply more money in circulation and so more ends up in investments of all categories.
A solid contender is this writer, who I follow on Twitter. This was the first article I read of his (which directly references Thompson) and I was absolutely sold.
I know it's a bit of trope to say this on HN... but why not Lisp?
If I make the assumption that future ML code will be written by ML algorithms (or at least 'transpiled' from natural language), and Lisp S-Expressions are basically the AST, it would make sense that it would be the most natural language for a machine to write in. As a side benefit, it's already the standard to have a very feature complete REPL, so as a replacement for Python it seems it would fit well
>The 3,500-year-old city, named Peñico, is believed to have served as a key trading hub connecting early Pacific coast communities with those living in the Andes mountains and Amazon basin.

>Researchers say the discovery sheds light on what became of the Americas' oldest civilisation, the Caral.
Oldest civilization is a bit of a stretch. Earliest surviving structures is a stretch, but it's one we know about, so I guess they have to base it off that. More and more evidence is showing that humans were in the Americas farther back in time. While they weren't the builders of of fine stonework and megalithic structures like the Olmec (that we know of), there were certainly civilizations and cities before humans suddenly started building the massive pyramids and cities we have uncovered so far. There's a lot of secrets still hidden in the South American jungles.
These are totally different versions of the concept of "literacy", though. Being able to read/write abbreviations of "eggs, scrambled", or "oatmeal" falls well below sixth-grade reading level. Literacy statistics involve much more comprehension than reading/writing food orders. Plenty of illiterate people do work in restaurants writing food orders. This is just a systemized way to remember orders, one that is used across all Waffle Houses, so that an employee from one restaurant switching to another will be just as effective, with no cross training or cultural difference.
The parent comment you are replying to is making a statement about precision vs other metrics such as user familiarity, accuracy, etc. The size of an American Penny and a 9v battery are both very precise, the former even more so. The lack of universitality is a different argument, the tangent your comment discusses.
"Precise" has a precise meaning, and it was a pedantic (though in a way I appreciate) comment on that. Your lack of familiarity with "American" pennies does not change that they are a very well defined size.
This often comes up in science discussions because to many lay people "Precise", "Accurate" and other terms are used interchangeably, when they have distinct meanings
Well, authorities have also said the area around Palestine, Ohio, is safe after the massive toxic chemical spill, and I don't really believe that. I'm not arguing the water from Fukushima is not safe, but I will absolutely argue that one should be skeptical of authorities saying "do not worry everything is fine"
>6/7 people colluding in this way is highly abnormal-- even in the CIA, most people have some amount of integrity.
Yes, they probbably thought they were acting with integrity. It wasn't labeled as a bribe, it was a bonus for helping squash "a dangerous conspiracy theory with geopolitical implications", that the recipients happened to at least be open to.
In many of these situations, the people involved think that they are doing the right thing, even CIA officers staging coups or planning asssasintations. Convince someone they're doing the right thing and you can get them to participate in a lot of shady things.
The CIA have been masters of shaping their perception as "well any evil they do is necessary evil", particularly with members of congress
It's vastly different when it's a local outage and there's functioning equipment outside the effected area. How will communicate the needs of grid stations with no electronics, satellites, internet? How will this be coordinated? How will the trucks moving the equipment be able to refuel when the grid is down everywhere, and everyone is rushing to gas stations and clogging the freeways? How can even emergency services coordinate responses?
If transformers do blow, the big ones at substations and stations... We don't tend do keep spares of those on hand. They're very often made to order, with a multi-week lead time, and that's with a functioning power grid to produce and coordinate them, again.
If you were to eliminate 10% of jobs with no replacements available, in the span of say a year, that would likely be a civilization ending development. People unable to feed their families tend to take drastic actions.
Additionally, even if Toyota were to get breached, they would not get my data
