    [Survey] Duplicates in code documentation?

    Posted: 27 Sep 2018 02:18 AM PDT

    We are a research team that works on Software Engineering at Bordeaux University, France.

    We are conducting a research on duplicates in code documentation.

    If you'd like to participate to our study just fill this short form (5min max):

    Using Information Theory to Explain Time-Dilation

    Posted: 27 Sep 2018 01:55 AM PDT

    Hi All,

    I've been conducting research on what are (hopefully) novel applications of information theory and computer theory to physics and image recognition. I shared the image recognition algorithms that I came up with on this subreddit, which seemed quite popular, so I thought I'd also share the model of physics I came up with that is rooted in the same ideas.

    The core concept is that elementary particles are discrete, combinatorial objects, that contain a finite amount of information (i.e., the information that describes their properties, like charge, mass, etc). I then show that if we assume that energy and information are proportional to each other, then with some technical assumptions, the model produces the same equations for time-dilation as the special and general theories of relativity.

    Though the subject matter of the paper is technically physics, it is really a paper on discrete mathematics, information theory, and computer theory, and so I thought it would be interesting to this crowd.

    College and a CompSci education

    Posted: 26 Sep 2018 05:10 PM PDT

    I am applying to college in the next month and I was thinking I wanted to go into business, however I recently decided that computer science is a much better fit for me so I have a few questions.

    1. Is a liberal arts school (like Butler) off the table? I have read that a BA in computer science is basically useless, is that right or does that not matter.

    2. Any CompSci graduates willing to suggest colleges I should look at. I really want to look at some good options but I haven't found many that are realistic.

    3. What are the differences between a CompSci major and Business majors in terms of job opportunities. I have read that CompSci majors have a higher out of college salary but does that continue to increase as you move up in the world like business does? Ex. A high level business exec could make up to 7 figures with the right job, is there any comparable computer science based positions?

    Using Information Theory to Compare Images

    Posted: 26 Sep 2018 05:05 AM PDT

    Hi All,

    Thought I would share an algorithm I've come up with that uses information theory to compare images, since the initial results suggest that it works quite well.

    Just like a related algorithm for feature extraction (post here), this algorithm does not make use of any machine learning or other statistical techniques, but is instead entirely deterministic. I believe that the complexity is O (N1*N2), where N1 and N2 are the respective number of pixels in each image, but I have not confirmed this.

    Here's a link to my blog post that explains the algorithm, provides examples, and contains the code for the algorithm (written in Octave):

    EDIT: I've received a comment saying you need to be logged into researchgate to see my post / download the code, so just in case, here's a copy of the post on my personal blog:

    In a CPU pipeline of 5,10,20 stages, how can new instructions be filling in and crunching an answer before it's even calculated the final result of the first instruction? Does it just hope it guessed right?

    Question about Byzantine fault tolerance

    Posted: 26 Sep 2018 08:32 AM PDT

    I'm looking through this presentation on Byzantine fault tolerance and I found a statement that I don't understand.

    On page 28 it says this: If n is not evenly divisible by 3, we increase it by 1 or 2 to ensure that n is a multiple of 3

    How is this allowed? Won't adding processors change how this all acts?

    Is Turing's halting problem "relative" to the hardware used? Or is it "universal"?

    Posted: 26 Sep 2018 06:45 AM PDT

    Is Turing's halting problem "relative" to the hardware used? Or is it "universal"?

    Particularly, e.g. does the context of halting problem depend on e.g. Von Neumann architecture?
