Really interesting. Like @StukaFox I was thinking about the window issue. I've heard that one reason window shutters need to be open at take-off and landing is so emergency crews can look in as well as cabin crew looking out.

One funny point of wording too. At 13:24 when talking about sensor failure he says how redundancy in design is so necessary. In light of this I found it funny that his conclusion regarding pressure vessel structure at 22:37 was that having a hardened skin around an arched pressurised section is a waste because it makes the internal section entirely redundant. OK, so I agree with him on both points, it just made me smile.

Just want to mention that the 2nd sentence is kinda redundant.

Conserve, you conservative you.

That's redundant, and wrong.
You can absolutely be ignorant/uninformed and hypocritical, you just might be too ignorant to recognize that's what you are. Edit: actually, I think that's the norm. Rarely are people intentionally hypocritical.

I think---and it's just a guess---that this is supposed to be simpler and easier to maintain and use? In part because the engines are outboard and there aren't all the shafts going to and fro that the V-22 has.

However, I had thought that the criss crossing shafts were part of the military redundancy plan (like, shoot out an engine and limp home on a one---or at least, limp to a better sort of crash landing)---so I don't really know.

Anything that simplifies maintenance will make the fleet cheaper to operate.

Thats the problem, they've abandoned the more adavnced rockets the thing was designed for - I think the general consensus is thet SpaceX's massive reusable rockets have made the whole design concept redundant already - its another Spruce Goose I'm afraid.

So there's no redundant mechanical VSI on a 767? Wow.

Good point, the word "idiot" is completely redundant when describing a flat earther :-)

Very cool.

I sure would have thought that it would be a platform with hundreds of partially inset mouse/trackballs, rather than treadmills on axes 90 degrees apart. I mean ... sure, any 2D vector can be split into a sum of two orthogonal components. But with redundant inset trackballs you could get stuff like spot pivots that are much finer scale than the scale of the 2-3 inch wide secondary axis treads...

On the other hand, these guys actually have a working prototype, so they clearly thought things through and decided that the orthogonal treadmill solution was better. Rubber meats road trumps off-the-cuff theoretical any day!

I think it was right on the rails. I live in Houston, was fortunate to have come through Harvey with little damage, and spent hours helping folks get out of the small boats that were rescuing people from their water filled homes. The reporting from the various news agencies was on TV pretty much 24/7. But they don't get it... sure, people outside of the situation want to know what's going on, but some of the most inane, redundant, pointless and heartless questions in the world come out of the mouths of these reporters who feel they need to just keep on talking. On more than one occasion, we had to tell reporters to get the fuck out of the way so we could do our work instead of pausing to allow them to conduct an interview. In a situation like this, where people have lost EVERYTHING they own except for the clothes they have on, and have spent hours scared, cold and not knowing if anyone is coming to rescue them, how the fuck can anyone with an IQ bigger than their shoe size think it's a story that wants to be retold in front of a camera? We helped little kids out of boats, with their parents coming along a few boats behind, and reporters walking up to these shivering, scared kids to ask them about any pets they might have left behind or been unable to rescue - to get them to cry. That's inhuman. If it were me, I would've shoved that microphone down that stupid woman's throat. This isn't reporting, it sensationalizing. But I guess we wouldn't expect less from CNN. These people aren't reporters our journalists, they are pond scum.

If you can go to all electric motors, redundant ones at that, you can cut out a ton of the spendy maintenance that forces helicopters to charge thousands per hour of operation. And fuel savings are just icing on the cake.

Oddly, I also thought that it was one of the least scary books that King has written. I read a lot of King when I was younger and some of his stuff terrified me, especially some of the short stories.
But IT was almost more fantasy than horror.

Making your antagonist a creepy killer clown is almost redundant, as I'm pretty sure that ALL clowns are creepy and evil...

or in the case of Insane Clown Posse, fucking stupid

Serious contender for comment of the month over at NC. Excerpt:

Flyover people and the uncomfortable urban poor fight the never-ending wars. We provide commodities like food and coal and oil and metals. We provide cheap labor. Comfortable people have decided that most of us aren’t really needed. Immigration, free trade, and automation have made us redundant but we’re not going away. At least we’re not going away fast. Flyover people and the uncomfortable urban poor have no real place in establishment Democratic or Republican thinking. We are the establishment’s problem and the establishment is our problem.

Thanks for the congrats and the power points and holy shit I should be congratulating you on the crown!! Now that is quite the accomplishment. It'd be redundant to gift you some back PPs, I'm sure you have a billion anyway, but I can give you a sticker! https://www.youtube.com/watch?v=lEzrKWjhLEU

Lol. Lebowski.

I'm studying mechanical engineering (hons) with masters in biomedical engineering. It's a head fuck. I don't think anyone offers firearm design as a major itself.

The trigger finger is the primary safety (debatable), and there is usually a secondary safety and sometimes a tertiary safety. It's true that not having it is different than removing it but sometimes they are redundant. For example the palm safety (a tertiary safety on most guns) is often pinned to turn it off permanently because it didn't add any real benefit.

The particular gun in question looks like a CZ-75. A little hunting in the Youtube comments and other people agree. This particular model originally had a firing pin block which was eventually removed on later models (that have the same internals) because it wasn't needed (probably because they also have a thumb safety). This allowed for the short reset disconnector to be put in place (which is a factory part). So CZ ships two lines of the same gun - one with the firing pin block and one without. You're not suddenly unsafe if you remove it from the model that has it. With the quality of the video the way it is though, it could end up being another gun entirely.

Yes, x-ray diffraction is not the only method. It was an example only. The point being that your average gun owner and gunsmiths don't use these sorts of techniques as regular preventative maintenance. And they don't need to, guns are cheap and replacement parts are cheap. If something breaks you replace it. Some parts are replaced on a maintenance schedule (springs spring to mind). Most people never fire enough rounds through their firearms to need to replace anything.

Factory condition firearms malfunctioning is not rare. Factory condition firearms self firing is quite rare. But several model firearms have been affected over the years (meaning millions of firearms). But usually the problem is with a small batch of firearms from within those millions but they always do a blanket recall.

I agree, unintentional firing of a gun is almost always user error.

I still don't believe their is enough information from the video and accompanying text to make a judgment call on this guy.
