Doesn’t Biden have a broken foot that hasn’t healed very well and makes him shuffle around a bit?

Two meetings a day sounds like luxury to me! I don’t have ADHD but meetings still absolutely kill my productivity. The switching penalty for technical tasks is much higher than non-technical people realise.

This video has a great comparison of different locking nut systems and how they hold up against vibration:

Just a small note that the businesses only have to open source their version if they release it. If they just use it internally then they don’t have to distribute the source code. So it depends on the use case.

More similar to Sunak calling the current General Election. It’s very unlikely they will win but they have to do something rather than let it get even worse!

I don’t know about your personal situation, and it may be different for whatever you are suffering with, however the part you quoted is true for a lot of cases.

Having just looked after my wife through a period of ~3 years really severe depression I’ve seen it first hand, it completely changed her personality and outlook and she was saying all kinds of stuff she’s quite embarrassed by now. She genuinely couldn’t think straight at all or see any way out, and in that moment if offered the choice to die she might have taken it (a fact she is quite scared by now, having mostly recovered).

Similar story with my brother, who has bipolar… when he’s manic he has an absolute inability to hold a train of thoughts together for longer than 30 seconds. When he’s depressed it’s absolutely awful. He’s now stable and enjoying his life.

I’m not arguing that this shouldn’t be an option for some very extreme chronic conditions, but it’s obviously complicated.

Depends on the plane, if you’re on a 737 Max you might want to be alert so you can grab any bits of the fuselage that start to shake loose…

Aren’t they implementing manifest v3 for addons soon, which will cripple adblockers on chrome?

These guys have an incredible range and mix up different styles in a way that is quite unique. I’m not normally someone who pays that much attention to drums but their drummer really is amazing. The singer can do both clean and ‘dirty’ vocals.

First time in ages I’ve been excited about a new band!

Yeah I don’t disagree with what you’re saying, we don’t put fresh grads on jobs without adequate supervision on the design side either. On both sides of the “fence” you need the experience to produce a good product; the two jobs are different and should be complimentary.

The schemes I have worked on that have been the most successful have had the designer and contractor working together closely from an early stage to produce something that works well, drawing on the past experience of both to anticipate potential issues and design them out.

Personally it took me about 6 years before I felt I was good at design. Experience really does count.

Those fenders would have done basically nothing for a ship of this size. You’d be looking at a 20m diameter cofferdam full of concrete to be able to take a hit like that without failing, I did some basic calcs and the ship was about 100,000DWT so the impact force would be in the order of 315MN, absolutely huge.

Yeah, you’d struggle to design a foundation that could take a hit like that, it would be something like a 20m diameter cofferdam full of concrete. The ship that hit it was about 100,000DWT so the impact load will be something like 300MN.

The bridge did have some small dolphins / navigation guides in front of the piers but they were likely designed for a very small impact load from a small vessel losing control.

That ship was about 100,000t.

There’s a fairly crude equation in the American bridge engineering standard that relates impact load to the mass of a ship, which is:

P =√(DWT) ±50%

Where DWT is the deadweight tonnage, and P is the impact load in meganewtons.

So in this case P=315MN ±50% which is 315000kN or 31500 tonnes of force…

For comparison, I’m working on a project where we’re going to build a new concrete bridge on the ground next to where it needs to go (under a railway) then wait until we have a planned week with no trains running and push it into position using jacks. That bridge is a 60m long 20m wide 8m high concrete box with 1m thick walls and top and bottom slabs, and we think we will need about 30MN to install it (one tenth of the impact load from that ship).

So yeah… that’s quite a hit.

I think unfortunately most people shy away from technical things including reading technical documentation. The answer to that problem is to have someone in the team on site who does read it and supervises all the people who can’t or won’t (i.e. an actual engineer). I can see how the profit motive drives companies to cut these people out but it should be seen as essential part of the process for safety reasons.

In civil / structural engineering, quite a lot of UK legislation and codes of practice has been developed following government reports into engineering failures, such as:

Loddon Bridge disaster --> Bragg report --> BS5975 code of practice for temporary works design

https://en.m.wikipedia.org/wiki/Loddon_Bridge_disaster

West Gate Yara bridge collapse --> Merrison Report --> system of independent design checking and competency requirements

https://www.istructe.org/resources/blog/learning-from-history-box-girder-bridges/

I’m not an aerospace engineer but I’d like to think that something similar will happen in this case, although to be honest I’d be surprised if the legislation doesn’t exist already.
