    Kind of. With hoisting, the compiler/interpreter will find variable declarations and execute them before executing the rest of the code. Hoisting leaves the variables as undefined until the code assigning the value to the variable is executed. Hoisting does not initialize the variables.

    For example:

    console.log(foo);
    var foo;
    //Expected output: console logs ‘null’

    foo = ‘bar’;
    console.log(foo);
    var foo;
    //Expected output: console logs ‘bar’

    console.log(foo === undefined);
    var foo;
    //Expected output: console logs ‘true’

    This means you can essentially write your code with variable declarations at the end, but it will still be executed as though the declarations were at the beginning. Your initializations and value assignments will still be executed as normal.

    This is a feature that you should probably avoid because I honestly cannot think of any good use case for it that won’t end up causing confusion, but it is important to understand that every variable within your scope will be declared at the beginning of execution regardless of where it is written within your code.



  • Maybe you should go read the article and actually read my comment. The article literally agrees with everything I said within the first few paragraphs. Negative temperatures do not and cannot exist under the classical definition, but the overall state of a system can reach a configuration that behaves like a negative temperature would, yet this is achieved by raising the temperature above what would tend towards infinity. Once again, it can be useful to represent certain configurations of systems of matter as a negative temperature with added context, and that’s why negative temperatures are a thing in science. It’s also why there are things like the summation of all natural numbers (1+2+3+4+…) being equal to -1/12. If you actually add up the natural numbers you get infinity, but ignoring that can yield useful results.

    You are also absolutely wrong about temperature being dependent on all energy. Temperature is literally defined as the measurement of kinetic energy in a system. Are you actually suggesting that if I put an apple on an elevator, it’s temperature is going to be increased when I send it up? Or that if I inject that apple with cold diesel fuel it will heat up? Those things would increase the energy of the apple, but not increase the kinetic energy and therefore the temperature does not rise.


  • What makes you say that isn’t what an absolute scale is? It definitely is what an absolute scale is. For example, distance is measured on an absolute scale. Negative ten meters would be equal to positive ten meters. In the classic definition of temperature measuring the total kinetic energy of matter, a negative temperature would be equivalent to a positive temperature, as it is measuring how much the particles are moving. Similar to velocity (also an absolute scale), if a particle is moving at a particular speed, X, then moving at that same speed backwards would be -X, but it is still the same speed.

    Negative temperatures are used to express something different from the classic definition of temperature, because the particles are not doing less than zero movement. Once a particle reaches absolute zero, it cannot move any less, but it can still have other properties that are directly tied to temperature change. Therefore, if purely expressing the classic definition of temperature, a negative temperature cannot exist, so any negative temperature would necessarily have to be equivalent to the same positive temperature. Of course, in any actual scientific conversation, the classic definition of temperature would be understood to be inadequate.




  • You may know the difference between a DAC and Amp, but you clearly don’t understand what I’m trying to say. I’m saying that a DAC doesn’t have its own power output. It literally takes a digital signal, and converts it to analog. In order for it to add any power to the signal, it needs to include an amplifier. Otherwise, the signal will always be a little bit weaker due to the power loss from traveling through the DAC. Most DAC units have at least a weak amplifier for this reason, but there are some units that are just a DAC. And the Amp part isn’t going to be controlling the digital volume, i.e. changing the system volume on your device. It will operate on its own volume control, so regardless of how limited the output is from your phone, it will still be made louder as it amplifies the volume independently of the phone. A unit that is just a DAC doesn’t have any way to amplify the signal it receives, so it will never be able to make it louder.

    You said explicitly that the android system will limit the output of any DAC, but that is wrong on multiple counts. The android system will not limit the output of a DAC because a DAC itself just 1:1 outputs an analog signal converted from a digital source so there is nothing to limit. The android system will also not limit the output from an Amplifier because it literally is not capable of that. That’s like saying your water faucet can limit how hot your water can get when you boil it on the stove. An Amp increases the power of the signal after it has already left the phone.



  • Lmao you are actually incapable of good faith, probably because of how obviously angry you are hahaha

    You are still trying to argue that your idealized theoretical version of communism is what needs to be accepted, but that a corrupted and condemned version of capitalism is what capitalism is inherently at its core. By your own standard, communism is equally abhorrent because of how it has been actually implemented in the past.

    A company getting bailed out is not capitalism. It is socialism. A capitalist society implementing corporate socialism is a corruption of the core ideology of capitalism. I will agree that it is the end goal of corporatism, but corporatism is a corruption of capitalism.

    And wow you really still don’t get the “no true scotsman” thing… I mean you probably do but once again, you are only putting bad faith forward. Since you clearly need it spelled out in detail, let me just copy this excerpt from the Wikipedia article on “No true Scotsman”:

    The “no true Scotsman” fallacy is committed when the arguer satisfies the following conditions:[7][3][4]

    not publicly retreating from the initial, falsified assertion

    offering a modified assertion that definitionally excludes a targeted unwanted counterexample

    using rhetoric to hide the modification

    Oops, you accidentally did all those things. You never retracted your assertion, you modified the assertion with further qualifiers, and tried to downplay that further qualification. You actually pulled a “no true scotsman” on a statement about someone being a scotsman. It’s so on the nose that you MUST be a troll lmao



  • Capitalism is absolutely not functioning as intended and has 100% been corrupted… if capitalism worked as intended, then why have companies been “bailed out” from failing naturally under capitalism? Capitalism has failed just as much as everything else has failed, and has been corrupted by the people in charge just the same. Communism doesn’t work, Capitalism doesn’t work, nothing we have right now works.

    And you literally still don’t understand the concept of “no true scotsman” lmao. It is also known as the “appeal to purity”. Let me be more clear:

    If someone has Scottish ancestry, is born in Scotland, naturalises to Scotland, or is born and raised within largely Scottish culture, they are Scottish. It doesn’t matter where that person was born or where they live. To say that someone cannot be Scottish unless they fit your specific definition and criteria is the exact fallacy being referenced, and you actually just doubled down on that thinking that it somehow makes you not guilty of that fallacy? Wild.


  • Lmao what side are you on? Your entire rhetoric is equally critical of and applicable to communism. If communism is allowed to be viewed as an ideology that has been corrupted, then capitalism is exactly the same. You don’t get to cherry pick and say “you have to look at A with rose-colored glasses and you only get to accept the idealized version of it, but you must only look at the bad things that have come from B and don’t get to accept its ideals!”

    Also you literally went full “no true scotsman” at the end, literally verbatim lmao. You actually just tried to say that one of the most well known fallacies is not a fallacy hahaha wtf is wrong with you
