    I haven’t done much MC Redstone in a long time (not in any significant way since some time observers were added). Couldn’t you take the inverse signal for piston 2 and put it in an and gate to piston 1 (or vice versa). Basically make your circuit (p1/2 is piston 1/2) : p1= observer && !p2. p2 = delayed observer.

    Edit: Actually, the delay might fuck this up. I don’t know if I can help. It’s been far too long. I don’t have the intuition for it anymore.

    I don’t recall totally how they’re used in Shrek, but I’m pretty sure it’s from the “transphobic trap” story. When Shrek was made it was perfectly acceptable (maybe even encouraged) to make fun of trans people and to call them traps.

    Sorry for the slur if it offends anyone, but I’m pretty sure that’s what this trope is.


  • I would argue they don’t know what that means really. Assembly is pretty much a mapping of words to machine code. It’s just a way to make machine code easier to read. It doesn’t actually change how it works.

    A compiler re-arranges and modifies things so what you write isn’t the same as the final program that is created. With assembly it is. It’s not really an abstraction, but a translation. It doesn’t move you further from the machine, it only makes it so you’re speaking the same language.


  • If you want some modern day fun with this, try the Zachtronics programming games; TIS-100, Shenzhen I/O, and Exapunks.

    Or, my personal favorite I only discovered somewhat recently, try Turing Complete. You start by designing all your logic gates from just a negate gate IIRC. You eventually build up an ALU and everything else you need and then create your own computer. Then you define your own assembly language and have to write programs in your assembly language that run on the computer you’ve designed to complete different tasks. It’s a highly underrated game, although it takes a certain type of person to enjoy.


  • This is pedantic, but assembly languages get “assembled” to machine code. This is somewhat similar to higher level languages being “compiled,” which eventually becomes assembly which gets assembled. The major reason why these are different is because a compiler changes the structure of the code. Assembly is a direct mapping to instructions. It just converts the text into machine code directly, which is why it’s easy to go from machine code to assembly but decompiling doesn’t give you identical results to the original source code.

    Also, binary and hexadecimal are just different ways to view the same binary data and aren’t different things. There is only “machine code” which is a type of binary data but you can view binary with any arbitrary base, though obviously powers of 2 work better.
