    Yes, there's that. The grading that is. I don't think its as difficult that we often make it out to be, but since engineering studies require a lot from the students, the notion that "we have to make sure that no-one can get away with coasting or cheating" seems quite spread (in the west at least, which is the only academic culture I can speak of).

    So since collaboration invites questions about who did what, and that could lead to "cheating", we're institutionally weary of it.

    If I had a dollar for every time I heard "the nation's largest tech companies are demanding these skills" (group work, collaboration, well-rounded, etc.) I could retire and start my own school.

    Well, being a university professor I've hear the same things, and you know, the companies are absolutely right. I think you're a bit too cynical. The reason they say these things ("we need engineers who can write and present and work well i groups") is that they do feel a real need, and also feel current graduates lacking in these respects.

    However, that's always been the case. It's a pretty stable criticism. So then you have to figure out why. And the answer is very simple and I always point it out when I meet industry representatives who lament the current state of teaching: "We could do that. We could turn out engineers who are much, much better at writing, speaking and what have you. But if we do, we have to cut something else. And we already have trouble cramming the vital subject matter into the education as it is. We've already, during my lifetime added a whole year to the master's engineering degree (from four to five), and you still have to spend too much effort to train them until they can become really productive. So do you really want us to spend more time on writing/presentation, at the cost of less time teaching programming and whatnot?"

    The answer is always, "Well, not not really..." and "Well, when you put it that way..."

    So, if you ask people what they want, its always always something else than what they would actually spend money on, and pay for. Schools as a general rule don't understand this (an affliction they share with many others in the public sector), the opt for asking and delivering that, instead of realising that wishing and actually putting your money where your mouth is, are two very different things.

    I've worked a plant with 50 turret lathes that date from around WWII - still going strong today. No CNC machine is going to drive them out any time soon for economic reasons if nothing else because CNC is expensive.

    Yes, but in a sense they're worse for employment than CNC are. With a turret lathe you'll get an even lower cost per item than with a CNC machine, if you have the steady, large scale, and stable-over-time, demand to keep them running.

    The demand scale is still: If you need a couple, do them manually. If you need more, CNC. If you need even more than that, build (or adapt) a specialised solution (aka turret lathe).

    I remember when I was at SKF, the production engineers could tell me to the cent how large a run of what part made the most sense to produce with what tools available. (Of course I was at the research laboratory where we had exactly one really skilled machinist, with two or three manual machines, as we only did one-offs and not enough of them to keep more than one guy busy.

    Back in the day though, you didn't have CNC, so either you used manual, or a turret lathe. The majority of machinist were busy doing the production work "in the middle" that CNC now has dominated. That's where all the jobs went, and that's why CNC was the killer it was/is. Not that we still don't people of all skills. (Even though they're getting harder to find.)

    I don't follow European news, but I doubt that very much.

The EU may want to punish the UK for leaving, but I doubt they'd do it at the risk of collapsing the EU economy.

    No, the message has been pretty consistent, pretty much from the brexit referendum. EU: "First invoke article 50, and then we'll talk". So, its not so much "leave already and then we'll talk", but "say you'll leave, and then we'll talk".

    On the subject of EU having to be "soft" on the UK, yes there are economic consequences, but there are also other, far reaching, consequences of being "soft" on the UK. It wouldn't set a good example for the rest of the bunch. So, economic consequences be damned, if they're let off too softly, there won't be enough incentive for the rest to stay in. So, the consequences to the economy probably have to take a back seat. And that's also what we've heard from the EU: "Don't think you can eat the cake and have it to" (paraphrase).

    (You lot did after all started a civil war because of someone wanting to leave, economy be damned, so there's historical precedent.)

    There's also the issue that the UK's GDP being so high because of their EU membership, so they want to stay "in" as much as possible. That's exactly what they said, then the EU answered: "Don't think so..." It would set a bad precedent.

    No that's (of course!) not how it works here in loser pays-land. For exactly the reasons you mention. Instead, the winner can only claim reasonable fees, so burying the loser in lawyer's hours wont work. There are set scales and standards so you can actually pretty well know in advance what it'll cost you.

    And also, if you win, but are awarded less than half of what you sought, that counts as "losing" from the perspective of fees. There's also middle ground where you're ordered to pay part (say 20%) of fees, depending on "how much" you lost. And no punitive damages. If the company needs to learn their lessen, they're fined.

    But of course a system like this wouldn't work for the kinds of legal problems where ordinary people would actually see a court. So there are special courts for workplace/employment issues, a special renter's court, etc. where it is cheap (free) and easy to have your case heard. We also have a system of "ombudsman" where there are special government prosecutors that will act on your behalf. e.g. when it comes to consumer issues, or discrimination.

    This means that the average Swede never sees the inside of a court, and doesn't even typically know anybody who has. Civil suits are almost unheard of. E.g. traffic accidents are handled by insurance companies, without any court involvement. And if you're unhappy with the insurance company, again, there's a special court for that.

    What we're talking about is the van!. Once the firing has stopped they follow a wounded man on the ground crawling along the curb. They make comments along the lines of "Just pick up a gun budy so I can shoot you!" (paraphrase). (Gloating, but that's not the point). This demonstrates that they're well aware of the rules of engagement that prohibits the attacking of wounded and unarmed on the battle field.

    Then the van comes around the corner. The father in the van immediately stops, goes out and renders aid. The helicopter crew is heard lying to their chain of command as they ask for permission to fire on the van telling their commander that they are "gathering weapons and bodies" (not exact quote). While the then current rules of engagement permitted attacking those that tried to remove weapons and the bodies of the fallen, they did of course not permit attacking someone who was giving aid to the unarmed wounded.

    Given the wrong information of course their commander gives them permission to fire, and they do so, with disastrous results. (Again with the gloating, clear lack of professionalism there...).

    That was beyond the pale, and a clear violation of not only international law, but also their own rules of engagement

    . Since they were safe in a helicopter several thousand meters away, they don't get cut any slack from being in mortal peril themselves, and they also had a bit of time, and other options available, so no excuse there either.

Actually, paradoxically, the "honey trap" theory is actually much more believable, than that.

(And even as a honey trap, the damage has already been done, so there wouldn't be any need for more, and those who prefer could have that theory intact).

Much more would have been made of it, but as the foreign secretary was murdered shortly after, and the prime minister stepped down due to losing the election for other reasons, there wasn't the political pressure. Even though we were asked to rendition more, not a single one was. To think that you could do the same to Julian Assange with no-one batting an eyelid is naive in the extreme.

    And there has been no admittance of any such thing, or even close to that. You'd need a credible source. The one you cite can't even get crucial details on the Egyptian case right, so why would their ramblings on Assange have any bearing on the truth?
