Fascinating stuff, looks like it was achieved on a regular lathe with with eccentric chucks (the piece is held off-center, so it doesn’t spin about its own axis, which is where the elliptical and circular shapes come from). This fancy turning art form advanced with the invention of the straight line engine and the rose engine (https://en.m.wikipedia.org/wiki/Rose_engine_lathe), which both use cams (protrusions and depressions on a wheel) to produce consistent rhythmic alterations in either depth or displacement. This art form is more commonly known as guilloche and is found mostly on watch faces and banknote currency, where it serves as ‘proof of work’ of extreme precision and craftsmanship.

>Lochridge also questioned OceanGate’s plans to install a monitoring system on the vessel to detect the start of hull breakdown. His court filing argued “this type of acoustic analysis would only show when a component is about to fail—often milliseconds before an implosion—and would not detect any existing flaws prior to putting pressure onto the hull.”

Well it's more than you may think (don't take only the fuel for the flight, but consider the whole construction of the thing).

But more importantly, they are making space a business. The first plane was a drop in a bucket, but it enabled modern aviation. If SpaceX hits their target of 10M per flight... rich people will go have lunch in space.

What? I very strongly disagree. But I won't elaborate more than you did.
If unsafe means “safe but the compiler cannot verify” then I guess just consider .cpp to mean “safe but the compiler cannot verify” and we have suddenly made C++ memory safe
Clearly nobody stopped this guy, so what was he whining about? It sounds like he was opposed to some completely illusory regulation.
Found this article [1] about the employee where this "millisecond warning" is mentioned.

It's been in most media on the past few days.

And yes, one has to wonder about a warning system that does not warm in advance and which operates in situations where no-one can do anything about it, anyway...

Edit: oh dear flood of replies!
The obvious counterpoint / explanation is that <<insert a few paragraphs about markets and the role of feedback loops in dynamics systems>>, therefore what you're being paid is, by definition, how much people in aggregate value your contribution.

(<<insert a text that counters the usual objections by pointing out that you're taking an integral over society, so lots of people paying little individually still adds up to a huge number>>)

This explanation is elegant. There's nothing obviously wrong with it, and I challenge you to find an alternative that's at least as fair, and that can actually work with real humans in real life.

And yet, decade by decade, it's becoming blindingly clear that this system is totally bonkers, and allocates rewards pretty much exactly backwards. It's like, holy shit, how much worse does it have to get before some philosophers or economists or mathematicians figure out a viable alternative that ranks occupations correctly?
With the right waveform analysis algorithm you could monitor stress, cracks and the progress thereof. Get more warning.
James Cameron has been giving various interviews where he speculates they probably audibly heard the delamination occurring with enough time to cause them to drop the weights and try to abort based on what he's hearing from people in the know within the circle of deep sea explorers involved in the search and rescue.

None of this validates using the audio sensor as a warning system because whether you have milliseconds or as much as a couple of minutes warning prior to rapid decompression makes no difference at the depth it occurred, but it does suggest the passengers knew they were doomed prior to the actual decompression.

Generation Identitaire was banned the 3rd of march 2021 using "loi du 10 janvier 1936". Let's see what the "lefties" said about this law in march 2021[0]:

"Dissoudre pour mieux régner" => "Dissolve to reign better" in english

"Une procédure à abolir ?" => "A procedure to abolish?"

« la question se pose de savoir s’il est pertinent de maintenir le principe même d’une dissolution administrative » => “the question arises as to whether it is relevant to maintain the very principle of an administrative dissolution”

Move fast and catastrophically implode things.
What strikes me is that this all sounds like bluster and prevarication around safety, rather than a situation where the safety has actually been thought through. This blog post also doesn't have any kind of links or references to any more in-depth discussion and ultimately seems even on the surface as though it would fall apart under scrutiny. For instance it's quite obvious that the reason the majority of accidents are the result of operator error is because mechanical failures are rare precisely due to classing and other forms of regulation. It does very little good to have "high-level operational safety" if the vessel you are in catastrophically implodes due to mechanical failure.

You only need to check the preview once before saving, and eventually correct an issue if some appear, which is quite rare if you are using a decent text editor.
That’s pretty wild. The operator was able to tell when they were going deeper based on the sound of the carbon fibers cracking in the hull.
I wish pg the best but I think everyone should know how much legal liability these kind of public writings creates. A person I know closely had 25 year marriage in CA and he always believed in love and lifelong relationship. But as their kids went to college, wife's priorities changed. She started affair, started helping out her partner financially etc. Husband discovered all these accidently from her phone. After many discussions, they decided to file for divorce. She apparently claimed in court that she owned majority of his company even though she didn't played much of the part. The guy had started the company even before marriage by his own money. She produced bunch of emails among friend where he appreciated her for help. That was the end of it.

It's easy to swept away in "love" and all that but the reality is that 50% of marriages in Western world ends in divorce. Always remember that people change over time.

> taking safety warnings as a personal insult is a red flag for literally dangerous narcissism

It certainly can be, but I have worked with people that absolutely use "safety" as a reason not to do anything, or as a reason to shoot down ideas from people they are competing against (different departments, possible promotions, etc). Like most things in life, this is not black or white, it's some shade of gray.
Well, the way in which we got there is in adding more features to the "obvious" answer: all any given site necessarily has to do, to have the same presentation as today, is place pixels on the screen, change the pixels when the user clicks or types things, and persist data somewhere as the user does things.

Except...there's no model of precisely how text is handled or how to re-encode it for e.g. screen reading...the development model lacks the abstraction to do layout...and so on. So we added a longer pipeline with more things to configure, over and over.

But - the computing environment is also different now. We can say, "aha, but OCR exists, GPT exists" and pursue a completely different way of presenting many of those features, where you leverage a higher grade of computing power to make the architectural line between the presentation layer and the database extremely short and weighted towards "user in control of their data and presentation". That still takes engineering and design, but the order of magnitude goes down, allowing complexity to bottleneck elsewhere.

That's the kind of conceptual leap computing has made a few times over history - at first the idea of having the computer itself compile your program from a textual form to machine instructions ("auto-coding") was novel and complex. Nowadays we expect our compilers to make coffee for us.
The reason I use Rust is because I can bypass all this messy business altogether and have my sensible patterns wrapped in a usable syntax and enforced by the compiler out of the box.

Whenever people say "just follow these rules" I read "just add this extra mental burden and do not slip up". Computers were invented to automate things. Rust automates ownership and borrowing rules. Suggestions like "do not forget to initialize unique_ptr with something" are not intelligent solutions.

Could be? The whistleblower found visual defects in the carbon fiber before they even started using the sub. That's why they fired him. They eventually found more damage and repaired the hull in 2020/21.
> While classing agencies are willing to pursue the certification of new and innovative designs and ideas, they often have a multi-year approval cycle due to a lack of pre-existing standards

"...and although that approach is perfectly reasonable from an engineering standpoint, our commercial model can't accommodate it."
Bridging the gap between neural networks and functions
That's exactly it. If OceanGate had build and dropped a few dozen of these hulls empty, as many times as needed to reach failure, whatever design flaw caused the implosion almost certainly would have been noticed. It's the hubris of diving in what amounts to a prototype that's at issue here, not any fundamental technical mistake.
In Rule 3:

struct Ship { int fuel; };

This is just simple prejudice.
If you have a high ISP engine that is low thrust, your rocket will either not get of the ground or if it does get off the ground it will suffer from a very high amount of gravity loses. High ISP on the engine doesn't matter when your rocket spends a long time just fighting gravity.

High thrust to weight ratio is important for a rocket. The higher your TWR the less gravity loses your rocket suffers.

There is a reason most rockets main liftoff comes from lowers ISP RP-1 engines or solids rocket. High ISP hydrogen engines just result in losses.

SpaceX Raptor actually deliberately reduced its ISP to increase its thrust.
And yet they allowed passengers to control the sub. Theres a video out there where one of the passengers hit the ground with a loud thud while at the controls
I think you are way overestimating 1600s florence and underestimating 1600s england.

> England is on the edge of Europe, quite provincial, not in great power.

We are talking 1600s england, not 600s england. During Cromwell's time, england was easily a major european power settling colonies in the new world. Far more powerful and far more important that italian city-states like florence.

> To go to Italy was to put yourself right in the centre of European culture

By the time cromwell was born, the italian renaissance was a distant memory. Shakespeare was the one advancing european culture, not dante.

> Especially Florence, where Cromwell ended up, was the epicentre of civilisation and culture.

No. The epicenter of civilization and culture moved west and north of florence by cromwell's time. Spain, France, Netherlands, England, etc were the new drivers of european civilization. Not florence, not italy.

> not just speaking Italian but a bit of German a bit of Spanish, fluent French and also reading Latin,

Pretty much what most educated europeans could do.

Actually, it's also the job of lead or senior engineers who have to teach their experienced and educated teammates how to read and write a state diagram and how to use it in order to show them why the code/service in question is unreachable from the current state -- and should remain so.
> The craft survived several launches - that proved it can do it.

Exactly, that's my point. I didn't realize that (this present catastrophe notwithstanding) that carbon fiber could even begin to have such compressive strength. How is the fiber formed in such a way to maintain that strength?
Hence standards of safety to weed out the incompetent. As usual, written in blood.
Anyone this cynical about marriage just shouldn't get married.
I have a friend who is a professor of history. He jokes that human history is basically us creating systems to solve problems, then time passes and we remove those systems causes “those types of problems never happen.”

Rinse repeat
James Cameron gave an interview where he claimed the carbon fiber hull concept was tested by a team competing to get down to Challenger Deep at the same time his team was - and the concept failed in testing. He also claimed many within the deep submersible community wrote letters to OceanGate warning them their plan was flawed and would result in catastrophic loss.

Specifically, the failure mode was delamination.

I can't vouch for how credible this all is - but, given how much disregard the OceanGate team had for safety, it doesn't seem too far fetched.

Definitely different. Prigozhin is accusing the Russian Military of firing on Wagner. Says he's going to take those responsible into custody. The FSB getting involved and the Kremlin commenting is Putin moving against him.

Seems mildly serious. Reports of checkpoints going up around Moscow and the security services going on alert. Don't really see how Prigozhin wins this but I suppose stranger things have happened.
The PR part also applies to Earth Observation Satellites (ESA and EUMETSAT). (Almost) any time you see a wide area picture of the Earth from Space (particularly around a weather event), it comes from NASA's MODIS instrument [e.g. 0].

The European (approximate) equivalent, AATSR, had a lot of really nice scientific qualities, but it was missing a blue channel, meaning that the 'true-colour' images it produced always had a blue tint to the clouds. There was a similar problem with the European geostationary satellite imager (SEVIRI) [1].

Scientifically, SEVIRI was incredibly useful (and far in advance of the American equivalent at the time), but the lack of a blue channel meant that it was never really used for those shots that made it onto the news (and neither was AATSR). When you have spent multiple billions on a satellite programme, you generally want the public to see it.

I remember being told at one point that this was considered such an issue that the Europeans would 'never launch a satellite without a blue channel again' - although that might be overstating it a little.

I'm struggling to find real statistics to back this up, but my suspicion is that other deep-submergence vehicles used to travel to this depth (and further) have a failure rate of 0% for manned missions.

My suspicion is based on the fact that I can't find any other stories of deep sea vehicles failing and killing their passengers in the last 40 years. DSV Alvin for example has completed 5,000 dives with 0 fatalities.

> They [inspections] do not ensure that operators adhere to proper operating procedures and decision-making processes – two areas that are much more important for mitigating risks at sea.

As a former tall ship captain:

No Shit. Ships stopped sinking when we started requiring inspections and design rules around stability and watertight compartments.

We largely eliminated a common failure mode, designer error, through inspections and classing, so now we are left with the harder failure modes: operator error.

I’m curious if the flag state will get involved here. It’s one thing to push the limits with experimental design (happens all the time in boats, airplanes and cars). It’s a while other thing to use experimental designs in commercial applications. There’s a good reason that the FAA doesn’t allow commercial operators to use experimental registered aircraft…
Can you explain how the root of trust is configured? Is it efuses or some sort of onboard mutable nonvolatile storage? If I buy a system with one of these chips in, am I likely to be able to set my own root of trust, or will the OEM have irreversibly set the root of trust to their own key?
Is that closer to the actual cognitive mechanics, or closer to a myth that's nevertheless useful for classifying people?

For example, in some empirical behavior research, person A seemed to have better snap decisions but poor at follow-though, and person B seemed to be asking about details... Has that nailed some key innate difference in how A and B actually think, or merely -- for purposes of, say, assigning military conscripts to jobs, or a huge corporate hiring machine that can't care beyond commodities -- at least it's a classification?

Maybe it's better than chance at predicting exhibited behavior (absent training), and we don't know that it reflects the actual cognitive mechanics?

Java is a much larger and more complex language than C. Consequently, it is much more fragile. I was one of the ones who thought Java was the best thing since sliced bread back in the 90s ("Write Once, Use Everywhere"), but I found it it very difficult to work with at times because you had to jump through hoops to get around those complexities.

And that's not including the bastardisation of Java that occurred when Microsoft tried to bring it down by changing many of the classes to something incompatible. I once got into an online discussion of something or other and couldn't work out why the other guy's code and results differed from mine. I then discovered that while I was using Sun's (official) Java, he was using Microsoft's (different) Java.

Don't get me wrong. Java is a good (overall) language but it's just not the simple and fast language that C is. There is the old joke that C makes it easier to shoot yourself in the foot. That is true, but it is also a very versatile and clean language.
