    Undergrad Logic Puzzle: The Locker Puzzle

    Possibly, perhaps also because the solution is similar to the one in this recent thread which seemed to me to deteriorate into a pissing contest.

    World Chess Champ Says Computers Ruined Chess

    Great to have you here: there are a few of us around here that remember what assembly programming was like back then.

    High School Why do people not notice the equinox when it happens?

    Jupiter yes but Saturn is about 13th at the moment and in a few months it will have dropped out of the top 20. I don't believe it will hit the top ten until September 2028 for a few months. https://theskylive.com/how-bright-is-saturn...

    High School Increasing the brightness of an OLED pixel

    Because the eye and brain detect red, green and blue light in different ways, to achieve an increase in brightness without changing the perceived colour the 3 sub-pixels are increased by different amounts. For an introduction to the complexity of this see for example...

    High School Increasing the brightness of an OLED pixel

    Neither. The relationship between RGB values and output power is much more complicated than that. There are also non-linear relationships between output power and luminance, and between luminance and perceived brightness to take into account, and also the fact that these relationships are...

    High School Increasing the brightness of an OLED pixel

    Really? Luminance is a photometric measure of the luminous intensity per unit area of light travelling in a given direction (https://en.wikipedia.org/wiki/Luminance). It is not measured on a scale of 0-255. I don't know how KDE's settings work but I would imagine that the 0-100 scale is...

    AI TPU vs. GPU

    Yes, working in a world where 256 + 1 = 258 would be disorientating (or is 512 + 1 = 512 worse?)

    High School Increasing the brightness of an OLED pixel

    Other. Exactly what 'other' is (or if there is even a meaningful answer to your question) depends on what you mean by "values" and "brightness" and at what stage of the image generation process you are "increasing the brightness" (application software -> operating system -> device driver ->...

    What does "Log in with your Google account" mean?

    No this is not a "Dark Design Pattern", it is the way that Sign in with Google (and any similar system) works: Google sends Cineplex a message saying "A person we know as Dave with the email address DaveC426913@gmail.com wants to use your site". Cineplex then uses the information in that message...

    Undergrad Curious About Symmetric Number Sequences

    You seem to be using the "reply" or "quote" functions incorrectly which makes it very difficult to reply to your messages: your own reply should not be inside "QUOTE" delimiters. But the math isn't correct: "[]" is not the symbol for subtraction and "→" and the word "gives" are not the symbol...

    Undergrad Curious About Symmetric Number Sequences

    No. Its not you. I am not sure why the OP did not simply write: "consider the following sequence": 1 - 2 + 1 = 0 1 + 2 - 3 + 2 + 1 = 3 1 + 2 + 3 - 4 + 3+ 2 + 1 = 8 1 + 2 + 3 + 4 - 5 + 4 + 3+ 2 + 1 = 15 ... 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 - 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 63

    Undergrad Curious About Symmetric Number Sequences

    This description may be meaningful to you, but when communicating with other people it is not helpful to use phrases like "the two 1s interact and produce a new value: 2". The way the sequences develop is quite clear from listing them, you don't need any words for this. What is not at all clear...
