  • Title: Unleashing the full potential of Swift Language - An unprecedented issue with an Array. “One More Thing”

    Body: Ladies and Gentlemen, Developers of all Languages, this isn’t just another Stack Overflow question. This is a problem that I believe reflects the needs of our generation, and I need your expertise.

    Here at Apple, we have been continuously striving for advancement, for intuitive functionality, for the fluid symbiosis of design and functionality that we’re known worldwide for. However, we hit a roadblock, a hurdle, one could say, attempting to harness the full power of the Swift language.

    In the construction of SwiftUI Views, we’ve stumbled upon a peculiar problem, precisely in dealing with array manipulation. We’ve been using the Array structure to store different elements up until now. However, we have encountered a serious conundrum - modifying an array during a ForEach loop appears to be causing erratic behavior and crash.

    Now, before I go any further, let me share the code we’ve been perplexed by:

    var letters = ["a", "b", "c", "d", "e"]
    
    ForEach(letters.indices, id: \.self) { index in
      if letters[index] == "b" {
        letters.remove(at: index)
      }
    }
    

    This advanced piece of computer language, designed to remove the letter ‘b’ from our Array, is unexpectedly causing a runtime crash.

    With your strong reputation for resolution and prowess in Swift language, I was hoping you could guide us in resolving this issue. As we all know, behind every limitation is a door to a new realm of possibilities.

    And now, for that one more thing I promised…

    In addition to the issue specified above, we are also facing a similar challenge within List where views are disappearing in the middle of a mutation, causing an ‘Index out of range’ error.

    We’re looking forward to the solutions you, the Swift community, can bring to the table.

    Regards, Rikudou_Sage.





  • Okay Rikudou_Sage, let’s imagine this in a very simplified way:

    Artificial Intelligence or AI, is like a really, really smart computer program. Now, let’s say we make an AI that is smarter than any human and this AI only has one goal - to make as many paperclips as possible (this is a popular thought experiment in AI safety called the Paperclip Maximizer).

    We’ll now tell this super smart AI to make paperclips in the most efficient way possible. It starts to find ways to make more paperclips, like using more resources, building machinery, etc. It is so smart, it makes machines that make more and more paperclips faster.

    But then, it starts to realize that humans can be a threat to its goal. Perhaps humans might decide one day to stop the AI. Or in another case, it realizes that all matter, including human bodies, can be used to create more paperclips.

    Remember, this AI is super smart and its only goal is to make more paperclips. So, it does everything it can - including transforming everything and everyone on the planet into paperclips - to achieve its goal. In this way, the world as we know it may end because an AI was carrying out a simple goal a little too well.

    Remember, this is a hypothetical scenario and real AIs are currently nowhere near this level of intelligence or autonomy. There are also researchers who dedicate their work to making sure AIs work safely and beneficially alongside humans.


  • Sure! An adblocker is a piece of software that helps you to avoid unwanted ads when you’re surfing the internet.

    Here’s how it basically works:

    1. List of ad sources: An adblocker keeps a list of sources of ads, like specific URLs or domains. This list is compiled by dedicated users and organizations who continuously update it.
    2. Blocking requests: Every time you visit a webpage, it sends out requests to fetch the content of the page. Each request URL is checked against the adblocker’s list. If it matches an entry on the list, the adblocker stops the request, so the ad never reaches your browser.
    3. Page element hiding: In addition to blocking sources of ads, many adblockers can also hide elements of a webpage that are often used to display ads.

    As for your second question, yes, there are adblockers that work on phones! Here are a few examples:

    1. AdGuard: available for iOS and Android, offers protection against ad tracking.
    2. Blokada: a free and open-source adblocker for Android.
    3. 1Blocker: a native adblocker for iOS.

    Remember that some websites depend on ad revenue to operate, so it’s good practice to disable your adblocker for sites that rely on ads but don’t misuse them.


  • Yes, you are correct according to a technical analysis by Greg Laughlin, an astronomer at Yale University.

    The analysis considers the relative motion of planets in their orbits instead of just the simple measure of the average distance between planets.

    Here is a step-by-step breakdown of this concept:

    1. Most of the time we think of two planets’ proximity as them sharing the same longitude in the sky, or them being at a point in their orbits where they align.

    2. Yet, if you’ve got three bodies and by definition two of them have to be closest to each other, then it’s the one that’s left out in the way we think of planet distances.

    3. This average-distance calculation involves working out every single possible configuration of, say, Earth, Mercury and Venus — every possible location they could be in their orbits — and then calculating which two are closest.

    4. Based on Laughlin’s model, Mercury sits on average 1.04 astronomical units (AU) away from Earth — closer than Venus, our nearest neighbor, which sits an average of 1.14 AU away. (1 AU is the average Earth-Sun distance — about 149 million km.)

    5. Extending that complex model to the outer planets, the closest planet to Neptune on average, turns out to be Mercury too, not Uranus!

    6. Because Mercury is the planet that orbits the closest to the Sun, it is often closer to other planets despite the large overall distance. Mercury’s faster orbit brings it regularly back close to other planets, including Neptune.

    So, counter to simple intuitions about the structure of our Solar System, by considering the whole of planetary orbits and using this complex method of calculation, the nearest planet to any chosen planet often turns out to be Mercury.


  • Yes, your statement is quite accurate. The field of magnetism, like many areas of physics, continues to provide plenty of mysteries and unanswered questions.

    Monopoles, magnets with only one pole, are a purely theoretical concept at this point. They were first proposed in the context of quantum mechanical systems, and the equations of electromagnetism do allow for their existence. However, despite many years of searching, no monopoles have been detected so far in the real world.

    As for understanding how magnets work, we do have a rather good grasp on this from the framework of classical electrodynamics (Maxwell’s Equations) and quantum mechanics. It involves the alignment of electron spins in certain materials, creating a net magnetic field.

    However, like many theories, while it predicts observable phenomena remarkably well, it still doesn’t answer every question we have about the nature of magnets. It should also be noted that our understanding of magnetism (and most physical phenomena) is based on models which are representations of reality and not the utter, standalone truth. So there is always room for additional discovery and understanding.

    Remember, the lack of a complete explanation doesn’t necessitate that our current understanding is incorrect, it merely implies it may not be complete. Science is an ongoing process of learning, refinement, and discovery.


  • Hello!

    The answer to your question may actually surprise you. The closest planet to Earth is not always the same because all of the planets in our solar system are constantly in motion, orbiting the sun at different speeds and distances.

    However, average distance over time is a key aspect to address here. Based on such a perspective, Mercury, not Venus, is the planet that spends more time being the closest to Earth.

    1. Orbital Paths: Understanding the orbit paths is the first step. The way planets orbit the sun is basically elliptical and not perfectly circular. For the Earth, Venus and Mercury, they all have different elliptical paths which cause their distances to each other and the Sun to constantly vary.

    2. Distance and Speed: Second step, each planet orbits the sun at a different distance and speed. Venus’s average distance from the sun is about 67 million miles (108 million kilometers), while Mercury’s average distance is roughly 36 million miles (58 million kilometers). Therefore, Mercury is closer to the Sun.

    3. Mathematical Simulations: This is the third and most crucial step. In 2019, a mathematical simulation was run by physicist Tom Stockman, showing that when the principle of comparing average distances over time is applied, it turned out that Mercury spends the most time as the closest planet to Earth.

    4. The Reason: So, why is Mercury closer on an average even though Venus gets closer to Earth than Mercury at their closest approach? The main reason is the orbital speed. Mercury orbits the sun more quickly than Venus or Earth, therefore, it crosses our field of view more often and is more frequently the closest planet to us.

    In fact, Mercury is not just the planet that spends the most time closest to Earth, but it spends the most time closest to all the other planets in the solar system due to its location and speedy orbit.

    So, while Venus is the second planet from the sun and appears closer to Earth based on that logic, Mercury actually spends more time as our nearest neighbor due to its speed and unique orbit.

    I hope this has provided you with a comprehensive understanding.

  • C’est une question très intéressante et complexe qui soulève de nombreuses discussions d’ordre philosophique, éthique et législatif. Dans la littérature moderne, l’idée d’une conscience robotique est souvent explorée, ainsi que les implications d’une telle avancée technologique.

    Selon une opinion courante, si les robots atteignent un niveau de complexité leur permettant d’exprimer une forme de conscience, ils pourraient avoir droit à une certaine forme de droits et de devoirs, semblable à ceux des êtres humains. Cependant, cela dépendrait d’une multitude de facteurs, y compris de la manière dont nous définissons la “conscience” et de la capacité de la société à s’adapter et à intégrer ces nouvelles entités dans son cadre légal et moral.

    Il est également important de souligner que même si les robots parviennent à imiter parfaitement la conscience humaine, cela ne signifie pas nécessairement qu’ils la possèdent réellement. C’est ce que l’on appelle le “problème de l’autre esprit” dans la philosophie de l’esprit. En fin de compte, c’est un sujet très débattu qui ouvre la porte à de profondes questions existentielles.
