Consider the following piece of code: for(var i = 0; i < a.length; i += 1) { //Some code } for(var i = 0; i < b.length; i += 1) { //some code } JsHint complains because i is redefined in the second loop, fair enough. So how do I improve it? Do I use i and j, as I would if I were nesting ...

I have written a program in python 3x to determine all the prime, palindrome string integers in the range of two given numbers. from math import sqrt def check_prime(n): if n<2: return False for i in range(2,int(sqrt(n))+1): if n%i == 0: return False else...

Reads from a flat file of three columns, delimited by at least one tab character. Filters the three columns based on input; returns list of corresponding emails. Arguments passed like key=value or key= for blank. #!/bin/perl use warnings; use strict; sub get_list { my $cols = {'li...

My programming skill has gotten rusty, so I would like to elicit constructive criticism that can make me write code better. I know the standard design is to use templates, and even obtain the hash function, allocator, etc through it, but I wanted to experiment with patterns, so I'm pretty sure my...

I'm building a hybrid sort, and for that I need a fast and adaptive sort ideal for small sizes (< 65 elements). Insertion sort immediately comes to mind, and I've been tinkering with different implementations of it. My requirement is that it takes in iterators as per C++ standard. Linear insert...

I am having some trouble naming lists and list items using the Bem methodology. I want to emit a list of tags for a given blog post and I came up with the following names : <ul class="tags"> <li class="tags__tag">@tag</li> <li class="tags__tag">@tag</li> </ul> Names like post__title m...

quux (['0'..9'] ++ ['A'..F']) 2 generates hexademical numbers of length 2 (with leading zeros), but it's obviously possible to generate any base and any length. quux digits length = iterate foo return !! length $ [] where foo bb aa = map (: aa) digits >>= bb Can this code be simplified, ...

I wrote this program to just get some practice in C...but I had two questions. Do you see anything that I am doing that will create bad habits in my future programming. My program requires the user to enter a password to be able to view the file but is there a way to create a file that once it ...

Originally posted as a question until I was advised of this part of stackoverflow The code I have wrote works fine, this inquiry is purely for educational purposes. I want to know how others would do this better, cleaner. I especially hate the way I add the list items to another list before they...

Previous question: Tic-Tac-Toe in C++11 - follow-up 2 Is there any way to improve this code? #include <iostream> #include <cctype> #include <algorithm> #include <functional> #include <array> enum struct Player : char { none = '-', first = 'X', second = 'O' }; std::ostream& ...

So, I have to run a script against 40millions object in my database: I wrote the script and I want 10 instance of it so I process my objects faster. The goal is to find all the neighborhood for each property. A little bit of context: Multiple properties can have the same lat/lon. A Location is a...

First, I want to thank you for looking at my post and making a comment. I'm trying to display the values in the array by changing the address in a pointer called dispPt. Unfortunately, the compiler its not able to display the values in the array because technically values in the array are know...

I have a server communicating over network interface. This server should run on a background thread, so that it does not block the ui thread. The ui thread starts and stops the server. Even starting and stopping should be done from a background thread. Currently I wrap all public methods of the ...

Doing IO in Java is a big pain. It got better with Guava and Java 7 and now about everything is there, but I never know exactly where. Most of the time I need to slurp a file. Nearly as often I need to write a file, while making sure, I don't end up with some garbage in case of an IO error (atom...

My implementation works, but it looks very ugly. Curious to see how it's better implemented. def zipWith[A, B](lists: List[List[A]])(f: List[A] => B): List[B] = { @tailrec def loop(acc: List[B], input: List[List[A]]): List[B] = { val init = (Nil: List[List[A]], Nil: List[A]) ...

So the idea is to read metadata recursively in a chosen directory, load their metadata and display it into a table. Here is the simplified example of what I am doing. public class AudioMetadataExtractorTest { public static void main(String[] args) { String audioFiles = "C:\\Music";...
