Reply to 'Highly Maneuverable' UFOs Defy All Physics, Says Government Study by Gari_305

From the article

>A new paper from the Pentagon’s All-domain Anomaly Resolution Office (AARO) and Harvard University confirms that these UAPs seem to defy physics as they lack certain tell-tale signs, such as an ionized tail or optical fireball produced by friction.

Also from the article

>The research around Unidentified Aerial Phenomena (UAP), which are really just UFOs by another name, is often wrapped up in the feasibility of intelligent life visiting Earth. But in a new draft paper (that has yet to peer reviewed), Sean Kirkpatrick, director of the Pentagon’s All-domain Anomaly Resolution Office (AARO), and Harvard University’s Avi Loeb, stripped away the more philosophical questions about life on other planets and instead focused on the physics of “highly maneuverable” UAPs specifically.
>
>While designing “physical constraints” in order to analyze these UFOs, Kirkpatrick and Loeb determined that the recent UAP observations do defy the laws of physics, stating that “the friction of UAP with the surrounding air or water is expected to generate a bright optical fireball, ionization shell and tail—implying radio signatures.” However, many of the UAPs studied show no signs of these signatures

Reply to comment by darkstarmatr in Will AI Replace Programmers? by Charlotte_D_Katakuri

There will probably be other breakthroughs in AI in the next 10 years but there’s also a chance that we will face roadblocks and find ourselves in a plateau, similar to what’s happened with other technologies in the past. The point at which we we will reach such plateau is almost impossible to tell but my guess is that there will always be a need for developers to perform the least structured tasks. The reason is that AI as we know it today is good at finding patterns in existing data and generating new data as an interpolation of those patterns, hence if a problem has no identifiable pattern or is different enough from the training dataset, it will be hard for an AI to generate a result.

Reply to Plastic pollution in oceans has reached 'unprecedented' levels in 15 years by ethereal3xp

The biggest source of pollution and danger to marine life comes from nets and the fishing industry. If you consume marine life, you are part of the problem.

Ecosystems at the brink of collapse and business as usual will lead to the entire demise of what we have left. Something's got to change and a shift in our food choices should be one of them.

Reply to What steps should i take to find a Blockchain related topic for my Masters Thesis/Research? by iamrohitmishra

Blockchain applications:

  1. Scamming people by selling them crypto currency
  2. Scamming people by running a crypto exchange and then pocketing everyone's funds
  3. Scamming people through pump and dump scams given the entire crypto market reacts every time you sneeze

There are infinitely many applications for blockchain, any time you need a regular proof of ownership or custody only with more steps (and more hands reaching into your wallet to participate in this new business method on computers on the internet with blockchain).

Reply to comment by [deleted] in Seems to me evolution found a solution to human obesity problem (Familial natural short sleep). Do you agree with my reasoning? by alex20_202020

Maybe you are correct, relationship does not seem logical. Faster, so what? But it was said in wiki, I just quoted.

However:

You seems to draw conclusions from anecdotal evidence and also from test that cannot isolate one factor influence from others.

BTW, how was your metabolism measured?

Reply to comment by zalgorithmic in A group of researchers has achieved a breakthrough in secure communications by developing an algorithm that conceals sensitive information so effectively that it is impossible to detect that anything has been hidden by thebelsnickle1991

>I don’t quite see how encrypting the data properly in the first place such that it shows up as some random distribution before embedding it with steganography is a wildly new concept.

It's not. I was getting at the converse idea: Given your encrypted data, steganography allows you to hide the fact that any encryption is even being used.

>If the distribution of encrypted data is that of noise, the image would just appear slightly noisy

Only by the broadest definitions of 'noise' and 'appear'. The image does not need to actually have visual static like a dead TV channel. That's a very simple way of embedding extraneous data into an image, but not the only way.
