Great little game! Thanks for sharing!

Just two little niggles:

- I feel like I should be able to fly over a runway without crashing in a landing/taking-off airplane. The vertical separation would allow for that.

- It would be nice to have an (optional?) zoom-out level, to have a bit more space for routing.

But a lovely little game, thanks again.

And the majority owner of Bosch is the Robert Bosch Stiftung (Robert Bosch foundation), which uses its dividends to fund projects in social sciences, public health and education.

And I was in Serbia lately [..]

With OP postulating that it is to enable corruption, and a sub-reply affirming that it is therefore the trait of a country in decay, bringing in Serbia as a counter-example is hilarious.

Serbia ranks 116th in the corruption perception index, Germany 10th. (Lower is better)

90-95k euro annually. [..] but is not something you can save up and build a future with or transfer to another country.

Nice disconnect from reality.

90k is more than twice the median income in Germany, and by extension, more than twice the median income of most European countries.

Blaming people for not speaking English in Germany is pretty weird. How about learning German instead?

As the poster wrote:

> At one point I ended up in the weirdest situation of my live were i translated the german instructions from the phone rep into english [..]

which implies that he does, in fact, speak German. The movers did not, though.

That's the way to do it, will work for Germany as well.

Yes, but please think of the Telekom and Vodafone et al shareholders..

Even if those companies did, eventually, relent to implement it that way, they would possibly find a way to link it to a predatory 36 month subscription or some other ridiculous terms to keep their rent-seeking.

In the meantime, the only option I have in my neck of the woods, is DSL at 4Mbits/s down - 0.5 up. At around 40 euro per month, I believe? Or Starlink..

[..] cruised at a slightly higher Mach number, I assumed that was enabled by the center of pressure being moved back a few metres.

In high-subsonic cases, it normally points to slightly better aerodynamics in the areas flirting with transonic regimes. The name of the game at those speeds is to try to delay the onset of drag-inducing shocks. These shocks will typically first appear on the wing, or in an area heavily influenced by the wing.

In the case of the -300, with the extended bubble coming down at about half the wing root chord, it is possible that the bubble downflow / low-pressure area positively influenced the flow over the wing to slightly delay the transonic onset and further effects.

Pulling the bubble further aft made things worse again.

Assuming that the boundary layer is laminar for the entire length of the extended part of the fuselage during cruise

Mm. No, I would expect the flow to be turbulent well before that.

and no additional low pressure transition (just one moved back, obviously).

Careful where you put your low pressure zones, the wing aerodynamics are critical and sensitive! :-) (see explanation above)

But to make things even more interesting, the 747- 300/400/8 cargo all use the short bubble. :-)

Thank you for sharing!

Just having went through a few episodes of violent thunderstorms with hail this month, I cannot help but wonder how resistant those glasshouses are?

Ah. It was based on a series of performance graphs from Boeing, dating back to my aircraft-design days where that very question was discussed and I was baffled enough by the contradiction to ask for detailed clarifications to the presenting professor.

Unfortunately, I don't have access to those old notes, and couldn't quickly find what I was looking for online.

So for now, due to lack of proper supporting arguments, I would say: scratch that.

The Cd is normally normalized by the wing area, and the wing planform was the same between the 747-200 and 747-300. So if the Cd was lower for the -300, the total drag should be assumed to be smaller.

I would have to imagine that the newer 747-8 would have the much lower pressurization

Two small corrections:

1) If it would have had a change in internal pressurization, the -8 would have a higher pressurization to allow for a lower cabin altitude pressure.

2) The -8 does not have a higher pressurization, because they did not change the fuselage construction. Newer airplanes have lower cabin-altitudes thanks to the use of composite materials, allowing for better fatigue properties.

It removed all the documentation and logging, reducing the size to about 2,500 lines. [..] but now impossible to understand.

Nice. Lol.

At this point, I gave up, threw out the LLM code, and rewrote the code. It’s currently about 1,400 lines (about 50% is documentation), and works great.

I've had similar experiences. But I must be "holding it wrong", judging by all the other articles on HN..

I’ve found utility in removing code.

I feel that doing the job with the fewest lines of code, is best.

And that is one of my gripes with AI models and code. They are so, so verbose. It's a nightmare.

"Why don't you let AI implement that small feature, it will be faster.", they would ask.

Well, because if do, it will completely pollute my carefully crafted interface that I kept small, simple and understandable for easier maintenance and extension.

And yes, I might spare a few hours by having _it_ work for me. But then I need to spend a more hours to clean-up the code noise and complexification.

Sorry for having polluted the conversation by bringing AI in, when for once, ironically, it was not about AI.. I needed to vent, while fully approving of your take.
