I would prefer something that would be along my lines for the simplification, area of introduction to Jquery and arrow functions, though I want to get better, and this is the best way I know how. I want it to be also a bit more efficent. function GeneratePersonWithList(amountOfItems) { var item...

This code returns a string of binary in 4-digit forms for a given hex in the form of string def str_bin_in_4digits(aString): retStr = '' for i in aString: retStr = retStr+"{0:04b}".format(int(i, 16))+" " return retStr.strip() for example, >>> str_bin_in_4digits("20AC") 0010 0...

I have written the below method to replace some of the email domains like @gmail.com and @yahoo.com with a given text. public static string RemovePersonalInfo(string input) { string[] tokens = input.Split(new char[] { ' ', '\t', '\r', '\n' }); string output = string.Empty; foreach (st...

I am writing a Go package that handles communication with BoltDB as a part of some larger project. I have 2 methods for interacting with DB. func Lookup(path string) (string, bool) {} func RegisterUrl(path, url string) error {} Lookup makes a request to database to retrieve corresponding url, wh...

I have these 2 version of code. Both are looking for all primes under a certain ceiling value. The first is testing against the set of all odd numbers. The second in testing against the set of all 6k-1 and 6k+1. In theory, the second version should be faster than the first. However the result sta...

As a part of my bash script, I am dealing with the optimization of some function, which take input csv file(s) and process it via some AWK script. This is the function, which operates on input file(s): rescore_data () { # accepting $str file(s) given outside the function in bash echo "DEBUG info:...

(Full code at https://github.com/dahosek/gftopdf2). I've written a first pass of a small library for reading the GF files output by Metafont. What I'm not too crazy about is that for the 11 distinct opcode types that I interpret, each of them is passed &mut ctx for the context struct that keeps t...

I got my code working with vanilla JavaScript, however I'm new to JS, so I don't know if the code is robust or not. Any advice to improve the code is welcome. let count = 0 function previewFiles(input) { const preview = document.getElementById('preview') const { files } = inp...

I'm practicing saving and reading serializable objects when a friend told me serializable objects have no use in real life, that I'd better focus on JSON or XML to serialize my objects when I came across this situation: I want to preload some FileFilters to use them in a JFileChooser dialog and I...

If I set x=["a","b"] and then run x.remove(x[0]), then my new x is equal to ["b"]. Then if I calculate len(x), then I get 1 (as makes sense because x=["b"] now. However, if I set x=["a","b"] again and do len(x.remove(x[0])), I get the following error: Traceback (most recent call last): File "<pys...

I am new to c# and decided to write a classic todo app. The implementation of my application now is like this: there is a Task class that describes the task. The List class acts simultaneously as a storage and has methods for creating, deleting, and displaying tasks. How good is this approach, ho...

In order to help with learning C++, I have been re-implementing games from old ZX80 books in C++. Here' the description of one I'm currently working on: You are a starship captain. You have crashed your ship on a strange planet and must take off again quickly in the alien ship you have captured....

Is there a way to simplify my code underneath? Basically I'm drawing a series of rectangles against each other on a mouse dragged event. The negative numbers are read from a 2D array in an other class (Board). I'm using positive numbers for dots (you need to connect dots with beams/blocks) also i...

I am building an application that needs to load 100-200 images (really only limited by performance) and display them to the user in a sort of gallery. A good analogy would simply be Google Images. In a linear implementation loading 100 images takes roughly 3-6 seconds, during which the GUI is fro...

I am relatively new to C++. When learning OpenCV I need to name a window. The title should not be changed afterwards, so I should make it constant. There are two options: const std::string title = "testing..."; or const std::string& title = "testing..."; Both do not allow us to modify the decla...
