I think many people reflexively assume that this in the same cost tier as a private jet. I wonder if it could eventually get to somewhere on the order of uber per mile, since a mile takes much less pilot time, and the maintenance requirements are presumably lower on these than on traditional single engine piston aircraft.

That’s something like $2k/resident to build, and then ongoing maintenance. Seems high for something that most will never use.

Joby plans to expand way beyond airport access, it’s meant to be basically flying rideshare. The key enabler is they designed it to be quiet enough to not annoy everyone around like a helicopter, so that it would be reasonable to have this thing taking off from residential neighborhoods. JFK access is just a very visible first test run.

There is a train to JFK, it does not take 20 minutes.

> There is a train to JFK, it does not take 20 minutes

An express train could. It would be a political non-starter since it does jack shit for the boroughs.

Multiple trains. You can take LIRR to Jamaica and transfer to AirTrain. Or take the A subway line. LIRR is faster but still like 45 minutes to either Brooklyn or Manhattan.

Well, in this case, we don’t need to argue about theory. The Joby has a tested range of 150 miles. They also tested it with hydrogen fuel cells and got >500.

Right, so when you factor in the legally required reserve flight time the battery powered Joby is only capable of very short hops. And that's fine, it's still potentially useful on a few routes and newer models will improve over time.

Sounds about right. A plane of comparable max take-off weight, a Piper Malibu, has a range of ~1500 miles (with reserve remaining).

This isn’t meant to slot into the role of other planes, though, it’s meant for rideshare. It can take off and land on my suburban lawn. There’s a lot to figure out before we can get to that point, so they’re just displace helicopters for the moment, but it can be a lot more. It’s basically the long awaited flying car, in nascent form.

And did our thinking about the importance of being good at arithmetic change in response? I think so.

We also used to be much better remembering things, when we relied on oral histories, our memory skills have degraded quite a bit. And there's a quote from Socrates criticizing how writing is a crutch that degrades our skill (https://www.perseus.tufts.edu/hopper/text?doc=Perseus:text:1... , the last bit). Over time, we've just moved to valuing other things more.

Seriously, these are an autodidact's dream. I've been having an absolute blast learning about stuff from government structures and the different approaches to fusion power to what types of electrical conduit are used for what applications and appropriate connectors, heat pump sizing, etc. It's so ridiculously empowering. All this info that you had to use an enormous amount of time synthesizing and studying is now available at everyone's fingertips. I think we're going to see an explosion in productivity on all sorts of fronts, not just writing code.

Yes, it needs to be sandboxed very carefully. It should have no way to access anything outside of the directories you mount in the sandbox.

I wonder what is the approach you taking? In my dev env we have .env files that supposed to have dev api keys for staging and testing. Production parameters stored in parameter store. There is also deploy script, that can deploy into production given there is a token in AWS CLI.

I understand there is a way to keep Claude inside working dir. but how to limit it from accidentally deploying production, modifying terraform deleting important resources? If dev can run AWS cli ir terraform then Claude can…

I only run claude code inside a docker container that only mounts the directory it's called in, and I make damn sure I don't run it in a way to mount a directory that has any creds in it other than dev infra. Do not mount a home directory with a bunch of . directories (.aws, .ssh, etc). The nice thing about the docker containers otherwise is you need to explicitly choose what to pass in, but getting lazy and passing in things just in case or because it's convenient is asking for trouble.

If you all think NAC is great, wait till you try liposomal glutathione (glutathione is one of the things NAC is a precursor for, one of the general take-out-the-trash compounds for your cells). Of all the supplements I’ve tried, it has probably the most immediately noticeable positive effect (maybe because you take it by leaving it under your tongue to be absorbed sublingually for a bit before swallowing). Generally leaves me feeling great, even if I was kind of dragging and tired beforehand.

I’d just keep in mind that you’re comparing a niche product from a startup breaking into a notoriously competitive market who are also doing the harder task of making these slim devices user upgradeable to a product from one of the largest companies in the world, with a CEO that is well known for being a master of supply chain, and with all of the economies of scale.

And they’re miraculously within 10-20% of each other.
