Our kids elementary school (Germany) recently voiced concerns that pupils - especially boys - do not fulfill the self defined learning tasks in the expected time.. There may be no upper boundary to how much out of touch educators can be.

Wasn't that the OPs argument? Companies have been building tunnel after tunnel [..] and optimized the process. No one had tried to large scale industrialize satellite + space launcher production before.

E-Ship 1 exists: https://en.wikipedia.org/wiki/E-Ship_1 They report fuel savings up to 25%, so it may be viable for some ships types and voyages. But a long way from propelling the whole ship.

It's a Ro Ro ship for rolling cargo. Not a big one and without the additional car decks an ocean going Ro Ro ship typically has, but for what it is the cargo capacity is reasonable.

A "normal" ocean-going Ro Ro ship would be over 200m long and quite a bit higher. Typically only the lowest deck can carry trucks and heavy loads and the upper decks carry cars. Their solution of only having the heavy load deck is sensible since they need a low center of gravity to counteract the sails and any added deck height hurts the sailing characteristics. With all that said, there is not much to scale it up. They could make it a bit longer but probably mostly easily: risk in bad weather, structural integrity demands from the added sails and all that may quickly add up.

This, I would go so far as keeping kids from social media is in conflict with (arguably) one of the most important jobs parents have which is getting kids into social interactions. (E.g. by teaching them good manners so others will play with them)

If the immigration is double the normal expected growth (~tripling the growth) it is not really tiny. It may very well be solvable, maybe even easily. But the problem in many European countries is that "the left" does not even acknowledge that this may be a problem and should be solved leading to many people voting for "the far right" that does acknowledge that this is a problem. In the US housing may not be the biggest issue, but the result is the same: the average voter can choose between "there is no problem, we can take in as many immigrant as we want forever" and "we don't want immigration".

Even the US is fairly far away from theoretical capitalism.. "No barriers to market entry" - ever seen that one in practice?

Secure Boot makes persisting malware in the kernel fairly difficult. Which IMHO made sense coming from Windows 7 where driver rootkits and boot kits where trivial. With today's main threat model being encryption malware I would agree that it doesn't add all that much for most people.

In addition to the technical details mentioned there is also the "social" part: Having Anticheat lets the company show they are doing "something" against cheating and keeps law abiding players from installing cheats.

Having rudder and propeller on different stations can be useful to organize work on the bridge, especially on a warship. The possibility of having the two propellers on different stations is imho insane. The only reason that I can think of is a runaway "safety" requirement ~"if one prop control fails you still must be able to take control of the other prop on a different station". That would fit what the article says about them essentially running in manual backup mode all the time and not in the intended mode of operation.

Maybe you didn't play Rome I? I also don't understand the death threats but I still remember playing Rome II on launch - after playing Rome I for years - and being absolutely baffled at how bad it was. Apart from the graphics nothing was better and a lot was worse. And I actively avoided playing siege battles, for fans of those it was even worse as explained in the article.

From what I have read the magnetic mapping it not enough for a position. It needs additional information to limit the possible positions. So the technology could be fairly accurate on a train or car. On a ship or airplane with an imperfect current position and course assumption it may not be very accurate and even drift over time.

I don't see the benefit for the attacker besides novelty. Am I missing something?

I barely find anything when using thunderbird search. Is that just me?

I can't relate to the bottom line "get a doctor" - even though it turns up a lot in these kinds of discussions. I live in a reasonably civilized county (Germany), but still know people who have or had trouble finding medical help with serious mental health problems (depression etc.). The idea of going to a doctor with "procrastination" seems very off in that context. Is it different in the US?

But that's a large part of the appeal. "Binary compatible with RHEL" sells Rocky, not "another Linux".

Reading that I am confused: isn't hardware abstraction what the Linux kernel does? It only becomes a general purpose OS with all the distribution specific stuff.

I agree and also think the author did a wrong turn somewhere after the original quote. One point of the quote roughly translated into the modern office is that dumb managers that create pointless busywork for others are part of big corporations and all together not a big deal as long as they are lazy dumb managers. Energetic dumb managers on the other hand may create a neverending spiral of problems and need to be watched carefully.

(On a sidenote there are several versions of the quote attributed to German generals - Moltke the elder, von Mannstein and von Hammerstein-Equord and I think most of them are better).

Advanced persistent threat.

Most sail concepts don't work with today's open deck cargo ships, that problem is solved by the OutSail concept.. but it still faces many more problems: - Is the connection enough to transmit the sail forces? - How will a ship with no sailing keel behave? - How will it affect balance and righting moment? - How will it behave after years of poor maintenance? - What happens if the wind picks up and the sails are not retracted early enough? ( The wind forces acting on a sail will at some point prevent you from hauling it in, but with traditional sails an axe can solve the problem )

I think you are mixing two things: dressing "correctly" is a status symbol and always will be even if it tends to be silly (number of pockets for woman, number of buttons for mens suits). The extreme we should keep fighting is when the norm becomes prohibitive, as in no breast feeding or not being able to ride a bike.

At my German university I could have graduated with next to no knowledge of programming and SQL and afaik the curriculum hasn't really changed.

If that where there would be no discussion about the switch to heat pumps. But it isn't. In old houses (bad insulation, old radiators) and edge cases ("winter") heat pump are not just inefficient they may not be able to heat the house at all (unless extremely oversized).

This is a huge problem in Europe where a house is expected to last a 100 years, in many areas much more.

Any statement would likely just contain polite lies. The concept of open access to things created with public money is not really a thing in Germany (I believe it is in the US?) and many agencies will fight it on pure principle.

Interesting Argumentation. But why can't China build a fusion reactor?

I would suggest that it is one form of politics becoming more and more professional. With help by professional staff politicians like Obama or Merkel have perfected the art of pleasing the majority most of the time while never taking any attackable position. One way to draw voters away from that is taking on "populist" positions. I have yet so see another way.

It is highly doubtful. German public authorities are notorious for not voluntarily sharing anything with the public.

I don't understand the underlying argumentation. Going "net zero" would require changing the live of every human on the planet, that's just not going to happen in a controlled manner. How about some achievable goals like not building new coal plants? And slightly less BS along the lines of replacing (houses, cars, whatever) with new slightly more efficient variations.

The keel is also required to prevent sideways motion which would eat up any gains made by the sails pretty fast. But I have no idea how well a cargo ship keel works in that regard.
