I have ended up in a “view all and block” mode rather than a “subscribe to a curated list” mode because of the smaller community. That means I need to block a lot more communities I am not interested in and users that are just… Outside my window of civility or politics that I can handle. Raging tankies, for example.
Yes
Out of curiosity, can you specify the topics or give specific examples of this shitty behavior you speak of? Without examples it is impossible to determine if you are discussing behavior that is straight-up pathological (e.g. name-calling) or people having a different opinion.
Aaaand this is what we were afraid would happen. Hamas doesn’t care about the civilians of Gaza. It is such a horrible organization, there are no words to express it.
There’s a whole army of men who want to be referred to as women and women who want to be referred to as men, so Stephanie -> Lady Gaga is pretty tame.
Am a woman. Girl’s best friends, in no particular order: IUD, my own bank account, vibrator.
Well then, please don’t visit.
Typically it is ultrasound, or X-ray CT. It does become difficult to do with large pieces and/or thick sections, but I don’t know if this hull was too large. However, if the manufacturing process were qualified using smaller pieces that were testable with NDE/DE or a full size piece that was DE, that would generally be acceptable for the large component.
I am a materials scientist working in another highly, highly regulated field, and part of my job is working on how to accelerate materials discovery and qualification for next-gen technology. Part of that means working with codes and standards bodies and regulatory agencies to get their acceptance in the new tech. It’s going to take some time, but it’s worth it.
Thus, the Titan story touches a particular nerve for me.
This entire tragedy could have been avoided if codes and standards were followed. The 2018 whistleblower was concerned about flaws in the carbon fiber composite that could grow and cause implosion failure after repeated pressure cycling. It looks like this is exactly what happened.
Let me point out that the pressure at 4000m is about 100 MPa: that’s above or near the yield strength of many common alloys. It’s a lot. Let me also point out that carbon fiber composite doesn’t yield, it just fails catastrophically, and also let me point out the idea of Weibull statistics, which look at the variation of things like yield and ultimate strength for brittle materials - there is generally a large range of measured strength based on the internal flaw structure of a component. Whistleblower asked for non destructive examination of the material to understand its flaw structure: an extremely usual request and generally something that everyone is on board with doing. Why not here?
Multiple people raised concerns about the safety of this sub. Rush ignored them all, or refuted them all with BS arguments. He said they didn’t need to qualify the sub because commercial subs were so safe over the last 35 years that it’s just human error these days, ignoring that the reason subs are safe is BECAUSE they are qualified, leaving ONLY human error as a problem source! It’s like saying “I don’t need to vaccinate against measles because no one catches measles anymore”… Because everyone is vaccinated against measles! But look what happens when vax rates drop: we get measles case clusters.
Regulations are written in blood, and this was ignored by Rush. The first thing drilled in to you in engineering school is that you must protect the safety of the people you are engineering for. Rush abandoned this principle out of greed and hubris. And now a teenage boy is dead who didn’t even want to go on this trip. It sickens me.
Please please tell me where I can find shitposting communities. Looking for some fun that isn’t mean or terrible to others.
You could thin it out with water too. Soylent comes as a premixed beverage or as a powder if you want it cheaper.
