    Just finished python crash course and I feel stupid.... Computer Science


    Just finished python crash course and I feel stupid....

    Posted: 31 Dec 2018 08:30 PM PST

    I finished crash course and saw a challenge online that asked you to generate the permutations of a given string and after 2 hours I gave up..... I could do it for 'abc', but didn't know how to do it for a string of any length. Did any of you struggle with these kinds of problems at the beginning? Is there any way I can improve at these because I just don't want to have to google for solutions all the time....

    Edit: Thanks for the help everyone. I think I was expecting to make too much progress too fast. I kind of get recursion now. To get permutation of a word of length N just get the permutation of N-1 and loop the final letter into each position of all of the permutations of N-1. Of course looping the function will get the permutation all the way back to length of 1, solving the problem. I need to learn to think like a programmer and hopefully will make progress. Thanks for the support.

    Incompleteness Ex Machina [pdf]: "Godel's work, rightly viewed, needs to be split into two parts: the transport of computation into the arena of arithmetic on the one hand and the actual incompleteness theorems on the other."

    Type theory: question about algebraic effects

    Posted: 31 Dec 2018 11:51 AM PST

    When it comes to effect systems, I always see the effects a computation performs (or, alternatively, the abilities it requires) attached to the result of the computation in the type signature. Examples of this include the language Frank from the paper Do Be Do Be Do (Lindley, McBride, and McLaughlin, 2017), in which type signatures look like this …

    T1 → … → Tm → [I1 … In]B 

    … as well as the language Koka, in which the function declared by

    fun foo(x: a): <e1,…,en> b 

    has type

    a → <e1,…,en> b. 

    What is the reasoning behind this syntax? It seems as sensible to me, if not more so, to associate the list of effects with the entire computation and not just the result type.

    What are the best resources to learn Android Development?

    Posted: 31 Dec 2018 07:59 AM PST

    Both free and paid resources would be appreciated.
    Could be any programming language (both native and cross platform).
