There's not much point in trying to hide what your doing, if what your doing is holding a public vote.


You have it somewhat backwards -- they wanted to get the word out, and the government had been suppressing discussion actively. They used IPFS to circumvent that.


>For functions of a single parameter, /partial operator/ is equivalent to /full derivative operator/ (for sufficiently smooth functions).

Are you pulling my leg here, or do I need to scrap my understanding of calculus?

If they exist, how could they not be equivalent?


Conditional on a non-military action which had already taken place.


"Already taken place" is not crucial, as the conditional can obviously be placed on it continuing.

Plus, an action like an embargo or sanction can be devastating to a country while still being "non-military". That old BS embargo on Iraq has claimed hundreds of thousands lives for example [1].

In fact, what we do have now is that "non-military" action happening, and no counter-response. So, it's more like them sucking up and taking it, with some verbal threats added to save face.

I concede the point, nuclear strikes on the US and Japan are reasonable responses.


> If I write a theory and take over an existing word in everyday use, it seems a bit much to accuse every one else of colloquialism when they use an existing but less strict definition?

It does, but engineering is a technical profession and it's practitioners are likely familiar with the mathematical concept.

I've read about applications of chaos theory in system design, and I expected 'Principals of Chaos Engineering' to be about that topic.


The problem I have with the name is that it feels like their audience is people not familiar with the mathematical concept. In other words, not engineers; in other words, non-technical managers. And that marks it as the latest marketing fluff being pitched by management consultants.


People familiar with the mathematical concept will almost always be talking about something like "nonlinear dynamics" instead, anyway.


Funny you say that. I had to restrain myself from using that term. Technically, chaotic systems are only a subset of nonlinear systems. For example, solitons are nonlinear, but neither are they chaotic.


I don't know the semi-conductor specifics... but it's a broad engineering concept.

Validation: Does the thing you designed actually do what it's supposed to do?

And the related concept,

Verification: Is the thing you build (and deliver) actually what you designed?

That specificity implies one of these cancers apriori occurs in 5% of the tested population.

Is that about right taking into account pre-screening? We can identify a population that has a 5% chance of having one of these cancers?


If these represent 70% of cancers overall and ~40% of the US population will get a cancer diagnosis at some point then it seems likely you can find many populations with more than a 5% chance of having cancer.


OK, but if I have a 40% chance of getting a cancer diagnosis at some point in my life, and they run the test as part of my physical every year, then presumably my chance of having cancer at the time they run the test is much less than 5%.


That just means you should not give someone the test every year.

At 70 people have a much higher risk of cancer than 7. Long term smokers have higher risks than non smokers. Combine multiple risk factors and find groups with 5+% risk of these kinds of cancers is not that difficult.

Which leads to my favorite way to think about it. One foot per clock tick of a 1Ghz processor.


Does this mean circuits in a 1 GHz processor can't be longer than 12 inches?


No information can travel more than a foot (11.8 inches) in a nanosecond. Grace Hopper used to give a talk where she held up a piece of wire that was that long to illustrate this limitation. [1]

The first Cray computers were designed in a cylindrical shape to keep the signal wires short. [2]

'twas an annular shape!

Ok..the backplane was annular
