    Am I understanding Landauer's principle correctly?

    Posted: 25 Sep 2019 01:34 AM PDT

    Landauer's principle says that there is an energy cost associated with each irreversible computation (namely, kT*ln2 per bit manipulated).

    The rationale given in the link above, is that if you perform an irreversible operation, then you are reducing the number of logical states. The output, in a sense, carries less information than the inputs together.

    So, according to the second law of thermodynamics, for the total entropy to not decrease, the number of physical states associated with the output logical state has to increase. But, if the number of physical states has increased, you get an increase in entropy (and so E=ST energy is emitted into the environment).

    How is that not circular reasoning? It's saying 'okay, for entropy not to decrease, the number of physical states has to increase. But if the number of physical states increases, the entropy increases'.

    "Histogram", by Tomas Petricek. "We represent programs as lists of interactions such as triggering an auto-complete and choosing an option, declaring a value, introducing a variable or evaluating a piece of code. We explore a number of consequences of this way of thinking about programs."

    Motorola 68000 core on the Capcom CPS 2 with gate array logic - can someone help me better understand the use case?

    Have all 64 bits floats been used?

    Posted: 24 Sep 2019 08:10 AM PDT

    Are there 64 bits writable numbers that have never been used in any processor nor written anywhere in a computer memory? We obviously cannot do an exhaustive list, but the maths tell we had enough time and computers to use them all, so what are the odds?

    Contains command for Access?

    Posted: 24 Sep 2019 10:25 PM PDT

    Im trying to make a query, and include a specific word, but can't seem to find the right command. Can somebody help me by telling me what command I could use in order to find a specific word in a Query for Access?

    How can my algorithm be exponential, if its ONLY constant tally outputs?!

    Posted: 24 Sep 2019 06:14 PM PDT

    It took me 45 units of time to write out tallies 1-9. And, it will always take me 45 units of time to write them out in any circumstance. By unit I mean each tally. Because the sum of integers 1-9 are 45.

    How can this algorithm be exponential when its a finite amount of tallies?! The tallies are fixed!

    print('Now, enter the input for transformation') n = input() res = list(map(int, str(n))) x = (res) for n in x: if n == 1: print("1_", end=' ') if n == 2: print("11_", end=' ') if n == 3: print("111_", end=' ') if n == 4: print("1111_", end=' ') if n == 5: print("11111_", end=' ') if n == 6: print("111111_", end=' ') if n == 7: print("1111111_", end=' ') if n == 8: print("11111111_", end=' ') if n == 9: print("111111111_", end=' ') 

    Note: I'm gonna be pretty mad at all the wikipedia articles and python manuals that I read if this exponential. In no way, can my mind wrap around this algorithm to be exponential to bit-length.

    Who are some of your favorite Computer Scientists?

    Posted: 24 Sep 2019 11:02 AM PDT

    Artists, Musicians, Scientists, etc are usually influenced by others that came before them in the field, or inspired by the work of others.

    Who are your favorite Computer Scientists and why / which Computer Scientists do you think deserve more credit than they get and why?

    PyMOL - or how to extract specific chain from 400+ files, when there are difficulties?

    Posted: 24 Sep 2019 05:41 AM PDT

    Hello,

    I have downloaded 400 specific PDB-files (ribosomes) and now from all of these files I would like to extract only one chain (one ribosomal protein) with some script made in python or bash. Have someone ever tried something similar? Is it possible? There is also complication that in all files isn't the specific protein named with same chain-name (somewhere it is chain H, somewhere 4, somewhere QT...). It sounds to me very complicated (it is task form mz supervisor) and I am not sure whether It is possible to automatize (or I have to manually in pymol extract the chain from 400 files).

    And one more thing - I have looked into text format of PDBfiles and it seems like there aren't specified the sequences with name of protein.

    Thanks

    Why don't we just send quadratic equations for the best compression method we could send the entire Internet backup in one TCP packet.

    Please Tell me

    Ver high level programming language

    Posted: 24 Sep 2019 10:03 AM PDT

    I started learning Python. It was given that python is a very high level programming language. What does 'very high level' mean here?

    Does it mean that it is closer to the human language and can be read easily? Source

    XOR logic gate

    Posted: 24 Sep 2019 08:28 AM PDT

    In my textbook, they gave an example of 0 + 1 = 1 but the '+' sign is within a circle. What does a '+' within a circle mean?
