The A220 is an absolute treat. Can't put exactly my finger on why, but it just feels right in size, noise, the little screens at the top. Flown it once or twice with AirBaltic, and would love to take it again.

AirBaltic was my introduction to the series as well and it felt for the first time in 30 years or so that I was in a modern aircraft. The last time before that was in a then brand new 747, which I absolutely loved to fly.

I had the exactly same experience with AirBaltic. It felt so modern!

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

Because the Software Update page under System Settings is all that normies will ever read and so what's in the text there is focused on normies.

Meanwhile techies may be interest in the CVEs listed in the security update list:

* https://support.apple.com/en-ca/125111

* https://support.apple.com/en-ca/100100

* https://developer.apple.com/documentation/macos-release-note...

And corporate IT types may be interest in enterprise features, like TLS behavioural changes:

But then you've got to ask why would we want an orbital Mars/Phobos/Deimos station?

Because Elon. Snark aside: the goal is Mars because it might be possible to colonize the planet and to have a place that acts as a reserve for humanity should shit really hit the fan (i.e. WW3). The moon isn't suitable as much for that purpose due to a complete lack of any atmosphere and because it's too close to Earth.

That’s not Elon’s plan. He’s too smart for that shit and wants to aerobrake down to the surface where there is abundant CO2 and probably H2O somewhere to make fuel for the return trip.

If you want passengers to want your plane, design it without sardines in mind; People don't like being sardines. I hope this is true. However, my sense is that the value chain is so elongated from aircraft designer/engineer/marketing/sales t…

With rare exception, people just buy the cheapest ticket. They moan and complain about this or that, but they still do the same thing. So, airlines structure and furnish accordingly.

> With rare exception, people just buy the cheapest ticket

With rare exception people just buy what they can afford. If people had so much money that they could afford to fly first class and it wouldn't impact their budget very few would get the lowest price they can find knowing that their experience in the air will be miserable.

That's surface habitation, not an orbital station around the planet or one of its moons.

The problem with using a space station as a waypoint on the way to and from the surface of a remote body is that it make the mission more expensive. For example, the Lunar Gateway increases the delta-v requirement by 15-20% (can't remember exact number) compared to a more direct mission. Which then, all else being equal, increases the total mission cost by much more than 15-20% because the rocket equation always wins. And that's just the actual visit, we're not even considering the cost of putting the station there in the first place.

So I keep going back to, why a space station? If we're going to spend all that extra money on turning hydrogen and oxygen into hot water, why put it toward a space station out in the middle of nowhere instead of, say, more time or more equipment on the surface of the body?

Also, IIRC, none of Elon's proposed mission architectures for going to Mars involve an orbital station. And, while SpaceX did get the Artemis lander contract, they weren't involved in the decision to have a Lunar Gateway.

This is eerily similar to the comment on the thread about LLMs that says software teams have to maintain a "theory" or model about how the software works and when they cant, they can no longer function beyond limited forms of maintenance. And in that comment the idea was that LLMs are accelerating this dynamic. I dont want to stretch the analogy too thin but in this case instead of LLMs being a catalyst, perhaps its…

Rensselaer Polytechnic Institute Has a degree that’s basically informatics management. My coworker took a class with case studies and the theory presented by that class was that all successful projects have at least one person who has fit the entire system into their head. They can tell you what happens if you pull on this thread. What the consequences are of trying to remove this feature. Lose them and you are fucke…

I've been on large projects where we didn't have one such person but was nevertheless very successful.

The key there was that one qualified representative for each part of the affected organization and other relevant parties in the core team, and there were frequent alignment meetings where they were all present. The representatives were close to the action, not some three-levels-removed manager.

In the meetings processes and such would get discussed step by step in detail, and any representative could chime in at any point to say "this won't work" or similar.

Hard to do though, and quite costly in terms of organizational resources required.

The basic Airpods are crap, noise cancellation is useless, they fall off the ear. You're better off with Sony or JBL at half the price. The Pro ones are good.

I don't own AirPods but it is a huge commercial success.

They were designed so that they'd get easily lost and they prevent you from replacing the battery. With enough marketing even a low quality product like airpods can be a commercial success

Isn't that something that's more the responsibility of the airlines, who decide how many seats are put in a plane, following the limits of the aircraft? Like if you want more legroom you take a more expensive ticket from a company that doesn't try to cram as many passengers in each plane

> Isn't that something that's more the responsibility of the airlines, who decide how many seats are put in a plane, following the limits of the aircraft? For pitch, yes. For width, no —- you run into quantization pretty quickly. The difference between sardines and standard economy is less than the difference between 3+3 and 3+2 — it’s not really feasible for most traditional airlines to choose a different number of…

There's no incentive. Passengers rarely know what type they'll be flying on when they book, and prioritize it over price even less. For airlines, a bigger airplane is a distinct disadvantage though, as it's operationally more expensive (increased cross section equals increased drag equals increased fuel burn).

They do :) And if the companies who produce these chips continue to make a healthy profit, why would they stop?

The scenario that comes to my mind is: these chips had a lot of potential customers 30 years ago, and now may be down to just one or two customers left buying too few units to make it worthwhile. Presumably, they have "guaranteed" buyers but also, if so, why would Airbus have issues sourcing CPUs, for example?

> […] too few units to make it worthwhile.

Not if the price of those units are really high.
