If the teacher was so wrong, explain to me how a majority of the students would have understood that question and been able to figure out the correct answer and provided the correct format?

But did they? How do you know? Have you seen the other students’ assignments?

Most likely, this specific task wasn’t actually a homework task at all but created just for this meme.

But teachers like this exist, and I stand by that that these teachers are wrong. Understanding and actually thinking about a problem are much more important skills than to obey blindly and follow pre-set directions without even reading what the question actually says.

I’d say, a student that answers the question as expected is failing in regards to reading comprehension.

And from my experience, if a question is worded as wrongly as the one in the meme, then half the class will have it wrong and there will be a group of parents at the next parent-teacher conference complaining about it.

True, even with the “Is this possible?” the student’s answer should have been ok. But with the “how” the teacher’s answer is plainly wrong.

In my country, the written final exams include a Q&A section in the beginning of the test, where the teacher and the headmaster are present, and where they present the tasks and students are allowed to ask questions. After that section, the headmaster leaves and students and teachers aren’t allowed to talk for the rest of the test.

I noticed a missing specification in one of the tasks. It was a 3D geometry task, and it was missing one angle, thus allowing for infinite correct results. During the Q&A section I asked about that, and my teacher looked sternly past me to the end of the room and said “I am sure the specifications are correct”. If there was an actual error in the specifications, the whole test would have been voided and would have to be repeated at a later date, for all the students attending.

As soon as the headmaster was out of the room, he came to me and asked where he made the mistake. He then wrote a fitting spec on the whiteboard.

I liked that guy. He was a good teacher.

That’s not what it is, no.

Teachers make mistakes, like any human being, and a good teacher can deal with the fact that they made a mistake and that a student found said mistake.

A teacher who insists on being right over being correct is a bad teacher, because a teacher is supposed to teach a child understanding and knowledge, not blind obedience above anything else.

That’s how you end up with a population who agree with the leader even if he tells them the sky is green.

Yeah, if the question was “Is this possible?” then the teacher’s answer would be reasonable.

But the “how” in the question implicates that it’s actually factual and the student should come of with an explanation how. Which they did perfectly.

Let me be clear: I wasn’t arguing for the law, only explaining how it will be likely used.

Depending on the exact content of the law and the first few precedences in court, what you are doing might or might not qualify.

Since you seem to only make attachments/utilities for commercial guns, it would be likely that that kind of activity is not covered by the law. Your guns are no “ghost guns”, they are commercial guns, legally purchased from a seller, with a registration number and everything. (I guess you purchased them legally.)

The gun is specifically targeting “ghost guns” that are created “at home” without registration numbers and stuff, so I don’t think that applies to you.

But who knows how exactly this is going to be applied.

Banning 3D printers for the purposes of stopping ghost guns is stupid, for the exact reason you named (lathe, mill, welders, …), especially because all of these tools are used for all sorts of stuff and creating guns isn’t their main purpose. The same cannot be said for the design files, no matter whether they are for a 3D printer, CNC machines or just a manual on how to build a gun the conventional way. The purpose of such design files is to create a gun, and that can be made illegal.

Whether it should or whether it would even help to stop ghost guns is another story.

I dont know the actual solution to this problem. At least for the religeous folks, it will have to involve religeous figures demonstrating acceptance and disavowing sects that refuse along with a lot of actual progress and exposure to get people to empathise and humanise lgbtq+ people and realise that theyre not a threat. Its possible, its actually quite easy once the balls rolling, but its a difficult thing to do to start i think.

In that regard, especially protestant churches are like the open source community: You don’t like what your church is doing? Just fork it and create a new variant that is even more radical.

In the case of the catholic church and other churches with centralized authority it’s more like “Let’s ignore what the Pope says and instead be holier than the Pope, but with holy we mean radical”.

Tbh, I don’t think the base problem is religion/churches here. The base problem is that a huge portion of the population are incredibly fearful and insecure, often bordering (or venturing deeply) into the territory of anxiety disorders. And instead of that getting addressed in therapy, populists (both political and religious) abuse that fear and insecurity to gain power.

The real solution would be easily available free therapy for everyone, preferably during young age, to make sure that at least the large majority of people enter adult life without being petrified of their own shadow.

Same as shock, so don’t hammer them in either.

I wish my printer was consistent enough between two prints for proving that two parts came from the same printer.

Many people here seem to misunderstand how a law like that will be used.

Police will not go knocking on doors trying to find out whether you downloaded a gun STL.

What they will do is (a) take down anyone advertising or publically speaking about the fact that they DIY guns with 3D printed parts and (b) if they catch someone who is also making guns they have one more thing to prosecute that one for.

And yes, known file hashes will also be blacklisted on places like Google Drive and secret services/police will get automatic notifications if someone uploads any of these known files to a service like that.

Fully 3D printed guns are nonsense, at least of you are using an FDM or resin printer. Filaments and resins are just not tough enough to take the pressure and even when using tiny bullets combined with extremely short barrels to reduce the pressure (which will make the shot extremely weak) it’s a 50:50 chance on each shot to blow up the gun.

And if you have access to a €50k metal SLS printer, you likely have access to much cheaper tools for conventional gun building.

What is a thing though is combining conventional gun building (for the barrel and the other main components) with FDM/resin printing (for things like the handle grips) to remove the need for skills like woodworking.

And yes, the STLs for that are just a google search away.

You could have written something very similar about the USA, just that their oligarchy started a few centuries earlier.

Or in other words: He’s pro after-birth abortions.

What about all the non-Jewish people in Israel and around the world actively contribution to, relishing in, and celebrating what’s happening? Can we talk about them?

What about all the Jewish people in Israel and around the world actively protesting against, writing against, and decrying what’s happening? Can we talk about them?

There’s idiots and great people in all ethnicities, and not understanding that fact is being incredibly simple-minded.

Fun fact: The faster a car travels, the bigger the spacing between the cars gets. That’s necessary to leave enough distance for emergency stops.

While the speed increases linearly, the spacing increases with the square, meaning at double the speed, the spacing quadruples, which in turn means that throughput (number of cars per hour) halves.

This is the reason why many regions use electronic speed signs to drop the speedlimit lower when there’s congestion. Because it increases throughput and thus reduces travel times.

The optimum speed for high throughput is 30km/h.

Counterintuitive as it might be, drivers should be all for 30km/h speed limit in cities, because it would make them get to work faster.

My Ender 5 has a modified E3D Toolchanger and MGN rails. Not very original either.
