DrGiltspur, a science en Real Engineering: The Questionable Engineering of Oceangate - an in depth analysis of the Oceangate disaster by an expert in composite materials engineering
@DrGiltspur@kbin.social avatar

My "favorite" part was when he read from the (now deleted) Oceangate blog post that effectively said "we don't bother with the mechanical certification process, since very few of the failures that occur in the world are due to mechanical faults".

Really? Could that be because the mechanical certification process actually works?

“We don’t need regulations! Theres never a failure in regulated engineering!”

I feel the need to step in here. Certification != regulation. Regulation means there is a body that can enforce the requirements with monetary or other damaging repercussions. What Oceangate faced were certifications and their decision to side-step them were met with no repercussions except their reputation with those who wouldn't ever want to step inside their sub anyways.

Point is - regulations would have prevented this, but there are none.

I get you’re point, absolutely. I didn’t mean to conflate them as the same thing.

However, at least what I thought - regulations would require certification before use (ie aeroplanes are regulated, and require certification)

In Oceangates specific case, they sidestepped regulations requiring certification by diving only in international waters? Their boat which took the sub out there would have been certified because of regulations?

That’s how I understand it

ShadowPouncer,

You're both right, but I'm pretty sure that you're having two separate but related discussions.

Certification by itself does absolutely nothing. It's a piece of paper.

However, it's a piece of paper that you can not get unless you've done a bunch of other stuff.

Regulations would have prevented this, because they would have required the certifications, which would have required the other stuff.

In this case, they didn't do the other stuff.

They didn't test the hull to see if it could take the pressure.

They explicitly decided not to bother testing the hull to see if it could actually take the pressure.

They certainly didn't do any fatigue testing to see how repeated pressure cycles impacted the material. The material that is extremely complex, and which nobody has done this with.

Because they didn't do that testing, they had no way to reliably know if other steps were required, like only using it X number of times, or establishing processes to do specific inspections to look for whatever kinds of damage might happen as a result of repeated stress.

So yes, if they had actually followed the process, this wouldn't have happened. They explicitly arranged to use the vessel in locations where they could not be held to the process.

But they didn't want to follow the process. Which means more than 'they didn't do the certification', it means that they also didn't do many of the other things that would have been required to get that certification.

And the lack of regulation meant that nobody could shut them down for those decisions.

Also? Just a side note, it’s very likely that people who were willing to cut corners around safety certifications… also probably didn’t have a proper maintenance schedule going on it.

XGC75,
@XGC75@kbin.social avatar

Yeah well put. It should be said that regulations OFTEN cite certifications from non-regulatory bodies. Regulators are often legislators and executors, not scientists that understand the rationales behind good practice. Certification bodies (like UL, as one example, or SAE for automotive) have the scientists to do the requirements.

Calling him evil is giving him too much credit. I think incompetence and gross negligence better cover it.

Yewb,

Yep he is an idiot people give him too much credit

Bonehead,

Never attribute to malice that which can be easily explained by incompetence or indifference.

Never assume that "malice" and "incompetence" are mutually exclusive.

I get the opinion - but it isn't always the distro owners... developers can upload their own versions to AUR if they want to. But it is a fair comment that even a keen developer is going to miss at least a few possible package formats.

What's the TL;DW version?

JonEFive,

Basically what we already know. Reddit is restoring comments that have been deleted by users possibly in violation of data privacy laws.

Louis goes a little farther by sharing the story of one particular user who tried multiple ways to delete their content including manually deleting every single comment one by one. Then to answer Reddit's response that user data is "anonomized" by disassociating it with the user account when the user deletes their account, the user points out that at least one of their posts has their full name in it, and by restoring that post against the user's wishes, they've violated California's data privacy laws.

He then goes into his typical cynical rant which I personally find entertaining but I know he rubs a lot of people the wrong way.

He also mentioned that Spez edited user content that was critical of him, without any indication to others that he was editing it.

It's an advertisement, it's specifically designed to make you associate positive thoughts with a corporation.

Can't find a lot of wholesomeness in that personally.

@tikitaki@kbin.social avatar

this is why everyone needs to edit all their comments instead of deleting them. i edited all the comments on my 14 year old account using a script. i got banned from like 5 subs in the process - but a few days later still not rolled back

remember the API is liable to change in the next few days.. if someone wants to do this they need to do it now while they still can

spriteblood,

I used a script to edit mine, and most of them have been reverted multiple times in the last week. Some of them retain my edits, so I keep running the script.

mark_hamill,
@mark_hamill@kbin.social avatar

Another user was having a similar problem with Reddit not retaining their edits when running a script. They fixed the issue by putting a time delay of five or six seconds between edits. Not saying this will work for you but might be worth looking into.

spriteblood,

That's the script I was using :(

Send_me_nude_girls, a opensource en Electromechanical Refreshable Braille Module : HackadayPrize 2023
@Send_me_nude_girls@feddit.de avatar

Cool stuff. Motivational even, to solve a complex issue like that.

prorester,

I hope they go on to make affordable, refreshable braille devices and tank the price of those devices for 3k.

bluGill,

How long do these last / how reliable are they. I'd love to have a braille display, but since I can see fine $3k isn't worth it, but $100 I'd have one to play with. However if I was blind I might be willing to spend $3k if it is better (note that I am well off and can afford $3k if I really want to - most blind people are not well as well off as me)

prorester,

If one for 100$ lasts you a year, then that's 30 years of one braille display a year. Do you believe the quality would not improve in 30 years?

bluGill,

If it lasts me a year, that is two days for a blind person. In just a few months the 3k.version is cheaper for them. I don't think quality will improve in a few months, more likely they go bankrupt from warranty claims (if open source develop a bad reputation and nobody uses it)

prorester,

you = generic you, not "bluGill". But even so, do you seriously think these components will last you 2 days? That's just an argument in bad faith.

bluGill,

You said that it was last me one year. Since I'm not blind, only someone vaguely interested that would be two days - not for me, but for someone who is blind and thus needs to use this all day.

As for how long it will last? That is an open question. It has small moving plastic parts Making those last is a difficult engineering challenge, so while 2 days (for the blind) wouldn't surprise me, I'm not actually stating anything. Fortunately it is easy for them to test: build one, figure out how fast blind people read, and then throw project Gutenberg at it repeatedly for a while to see how long it lasts. Since it is so easy I'll just stick with how long it lasts is a real worry, but I expect someone to do some tests and tell everyone. Ideally it would be the creators as they can do a failure analysis and maybe fix problems.

If it lasts a blind person a year this is a good win.

@mojo True. He made a good introduction into both tiling window managers and holding off his own opinion/decision until end of video and only spoke 2 minutes out of 38 as a final verdict. He also do not push people into one system, just offering options and an opinion. In my mind this was well done first look for people to decide what they try next and what they await.

However it should be noted this was all in X11 and not Wayland.
