    Cool features from esoteric or unused programming languages.

    Posted: 21 Feb 2022 06:35 PM PST

    I'm trying to learn things about the story of these features in compsi and see how it evolved so, I start:

    • Dependent Types like Agda or Idris
    • Prototype based programming like IO
    • Message passing everywhere like IO/Smalltalk
    • Effect handlers/Typed Effects like Koka or Unison
    • Variable indentation determines a block of code like Haskell
    • Tuple Spaces like Linda
    • Reactive programming like Esterel/Céu
    • Prolog's weird unification engine

    • Linear types / Levity Polymorphism / Higher rank Polymorphism.

    What would you recommend to study for non-major?

    Posted: 21 Feb 2022 08:14 PM PST

    Hello ladies and gentlemen!

    Recently I decided to change my major to Computer Science.

    I'm planning to study Python, Discrete Mathematics and Algorithms on my own before transferring.

    Would you guys recommend me to study something else?

    I appreciate you for reading this.

    Good introduction to (theoretical) functional programming for Mathematician?

    Posted: 09 Feb 2022 03:21 AM PST

    I've recently encountered HVM which linked to a book by Andrea Asperti and Stefano Guerrini, which does not appear to be a very gentle introduction to the subject.

    I have an MSc in theoretical mathematics with some basic Bachlor's level CS courses covered (computational models, data structures, complexity, a bit of graphical programming). What would be a good jumping off point into (functional) programming theory?

    Path generation algorithm

    Posted: 07 Feb 2022 02:15 PM PST

    Hello,

    We are currently developing a research project where the goal is to simulate a boat and guide it through a canal, with an enforced geography and wind conditions (somewhat random) we get at each time step.

    We have a 2D black and white map, and both the starting and ending pixels (we can say that the boat is represented as a pixel).

    Our current approach involves using a PID controller to optimize the boat trajectory given an optimal path, which we can compute ahead of time as the image is given (biggest is 6655 x 30807).

    We thought about using A* (or some alternative such as HPA*) or simple bfs, and have even implemented a working version, however, the generated path is far from ideal as it often follows the walls and can lead to a crash very easily.

    My questions: Do you know algorithms that would maximize distance from obstacles (perhaps they exist, unfortunately, I am not that familiar with robotics or gamedev and have not found anything relevant on the web), while optimizing for distance as well? Maybe you have other suggestions than the PID or the optimal path on how to optimize the trajectory? We welcome different ideas!

    We are mainly using Python, however we are not limited to the language, and C/C++ (or other) can be used for computationally intense tasks.

    Thanks a lot!
