> There is no hint that Apple intends to do anything with the Vision Pro, and they've already been scooped by Meta. I expect that's exactly what they have in mind. If they're successful, Meta's project will be to Apple's what early MP3 players were to the original iPod. The jury is out on whether Cook can pull it off.

It's more likely than not that they will, in my opinion. As an owner of both an AVP and Quest 2, the former is a lot nicer to use than the latter with the exception of VR games, and my hunch is that Valve is going to eat Meta's lunch for gaming with Deckard (which will be at least as good as the Quest 3, but much more open, paired with a vastly more populated and popular marketplace, probably won't treat PCVR as an a…

Of course the AVP is much nicer than the Quest 2. For more than 10 times the price it had better be.

It doesn't really describe the companies' different abilities but the design goals. The quest 2 was clearly 'make it as cheap as possible so lots of people can buy it' and the AVP's was 'make it as good as it can be, price is not a factor'

Still though, both products eventually get stuck at the same point: a killer usecase. Neither has a compelling reason to actually want to put it on. There's very few things that are better in VR and the ones that are are really niche. I personally love VR gaming and stimulations. I love VR for it and I use it a ton. But those are pretty niche.

But socialising in VR is not really a great user experience despite most of meta's focus going there. And Apple? They don't really have any usecase that shines. Maybe watching movies but even that works better on an actual TV as you can share the experience with others.

My understand is that the 737 Max was fine if they treated it as a new airplane. The problem was the put gizmos on it to make it behave like a regular 737 so pilots didn't need to get retrained on it. Those gizmos are what crashed it when you didn't know how they behaved when they failed.

The problem is that the whole point of the 737 Max was that airlines didn't have to treat it as a new airplane. If they did, it would have lost a lot of the value proposition and there would have been more support for an entirely new replacement instead. It would be a fascinating case study in perverse incentives and unintended consequences if it wasn't for the loss of life that resulted.

Doesn't that make it an even more important case study? I remember learning about the Therac-25 in CS undergrad specifically because it killed people.

> with large organizations where once their markets mature, everybody who can build a product end-to-end leaves or gets forced out, leaving only people with highly specialized maintenance skillsets It's not just building a product end-to-end. Tim Cook is a supply-chain guy. He knows how to build a product. What he doesn't know how is how to design a new one. This is the reason that all of the "new" stuff that has com…

My work laptop (Mac) needed an OS upgrade recently, top of the release notes was "added 8 emojis" - what? Why is this an OS level feature worth calling out

Text handling and Unicode support is part of any modern user-facing OS. New emoji is a highly visible user-facing upgrade.

The biggest tell will be just how over budget the development process becomes. Another issue in large companies trying to build something new is the scope creep which leads to committees and then decision by committee. If the folks leading this effort in Boeing are smart, they will keep the size of the team as small as possible. Maybe they will even hire some people back to lead this effort... assuming they can find…

1. Modern airliners with fly by wire have capability similar to MCAS the difference is it is not half baked but has numerous degraded states it can run in when sensors are out and pilots are trained on all that. Any new airplane will have that under the name “flight envelope protection” 2. The circular cross section is anti-human and is the reason my neck knots up when I think of getting in any plane of that class. E…

+1 on the Embraer. It's much more comfortable than a 737 or A320 while being much smaller. The advantage of doing a greenfield design completely to modern capabilities

Yes? Why do we need to colonize the moon with squishy meatbags with billions of years of evolutionary optimization for life on Earth? All these dreams of star-trek like interstellar travel (or even interplanetary travel beyond taking a selfie and going home) require major advances in the physics tech tree. Might come, might not.

Would you not like to see major advances in the physics tech tree? The way you get those advancements, is to have a goal. And funding. A moon colonization program provides both.

To use video games as an analogy: You can't invest all your resources racing up one tech tree; you have to build the whole economic engine to achieve those later levels.

"Moon base that produces positive economic benefit" is about 10 steps up a very expensive tech tree and we don't even know what the rungs are.

I also don't think this is very imaginative. If you want to colonize the moon, why send a man in a can? How about genetically engineering a human-ish that's better adapted to that kind of environment? That's the kind of technology advancement that makes manned interplanetary missions reachable.

Will it still be controlled by dual redundant 80286 chips like the MAX, with its software outsourced to the Indian 3rd party contractor?

Is the MAX really using a 286 CPU? Why would they pick that for a plane launched in 2014. I get that it's based on the 737 Next Gen, but they just opted to not update the electronics?

No. It is an FCP-2002. See https://news.ycombinator.com/item?id=23763398

One of the most exceptional CEOs I've worked with was a lawyer. I still think the proverb is largely correct, along with the other proverb about the exception proving the rule.

That's not what "the exception proves the rule" means. It means, when you see a sign that says an exception, "no parking Wednesdays between 8 and 12", it proves the rule that parking is allowed otherwise.

I have heard that phrase a million times and never understood it until your example. Thank you

A phrase does not mean anything by itself. People mean something when they use it. You could argue that expressions carry some meaning, by virtue of shared use. But your definition does not align with the meaning most people make of this specific expression as you can witness above.

The way most people use it is wrong though and not in the normal "language evolves" way.

The exception of a lawyer being a good CEO does not, in any way, prove that lawyers are not good CEOs .

A fully loaded 747 is extremely profitable, the large size has economies of scale. That's why the 747 was very very popular with the airlines. So, yes, a 747 burns more fuel. But the fuel burn per paying passenger is less .

It was an old airplane too and not as optimized as newer airplanes in terms of engines, aerodynamic design, weight and so forth. The A380 was a step up in size and had additional problems such as there not being that many airports which had upgraded their gates and other facilities to support an airplane that big.

As aviation technology improved, the 747 could not improve its aerodynamics and so became relatively costlier to fly. It's longevity, however, was due to it's cost effectiveness for several decades.
