This feels like a simple question, but I'm wondering what the best way would be to manage the elements of a private, fixed-size array. Context: I'm making a simple particle engine, and my Emitter class will smoothly interpolate between up to 8 colors per Particle, depending on the Particle's Lif...

In my application, there are three domains for the data, the first is a Length (measured in metres as an int), the second is a Time (measure in DateTime), and finally the Depth (measured by double). Effectively, my application needs to provide most of its functionality, multiplied by three, to t...

I have an array of Item objects that each have a string particular and a numeric amount. I want to put all particulars (separated by newlines) into a single string and the same for all amounts. Here's what I came up with: particulars = [] amounts = [] items.each do |item| particulars << it...

I have written this little tagging module to make it easier to generate small html snippets on the fly. The examples below show how this make things a bit easier. My question is about the handling of tags that contain either a single element like text or a list of other elements, like the tr elem...

I've created a simple Python program that checks the word frequency of a text and shows the results in matplotlib figure. My question is that how can I put this code into object oriented? And how can I put the figure into the canvas? Thanks in advance... from tkinter import * from tkinter import...

I want to create all possible combinations of points (0,0),(0,1)...(12345,6789) and then all segements from these points. The code i have written is simple with no optimization. Is there any algorithm to generate it in less time? Thanks in advance. public static void main(String[] args) { in...

I'm trying to understand DRY but my javascript skills aren't quite up to scratch to get this code as optimised as possible. Depending on the width of the screen the javascript animates a node and then loops another animation. Here is a JSFiddle to show you an example of what I mean: http://jsfi...

I have tried to write code of Box stacking problem (mentioned here)in C++ . Kindly give me some views on what mistakes I might have made and how I can improve. It is running for the two inputs I have provided. Thanks //============================================================================...

I wrote this unbalanced binary tree and would like to know how to improve the code and performance. If you can point out any situations that are not being handled appropriately, that would be great too. It supports element insertion, removal, search, iteration, tree balancing and encoding/decodi...

There is a recommendation not to use an Exception to control the flow of execution. This gives me a reason for doubt when I do something like this: public void initApplication(String input) { try { MyClass mClass = new mClass(input); saveToDatabase(mClass); ...

The question is very simple but also a bit theoretical. Let's imagine you have a long JQuery script which modifies and animate the graphics of the web site. It's objective is to handle the UI. The UI has to be responsive so the real need for this JQuery is to mix some state of visualization (sp...

I am quite new to event programming in C# specially in WPF. I have made a very simple core app which I am planning on extending. It's very simple as its purpose is learning curve and doing things the right way that's why I am asking here for a review and not help on building as most of the buil...

I have to work with a 3rd-party API that allows me to define and execute "commands", using XML. Since I don't like seeing mixed abstraction levels, I managed to remove all the inline XML / string concatenations by creating a simple XmlCmdBuilder object - here is the C# implementation (I have one ...

I used step 4 from the Angular tutorial to do some tinkering of my own. In that particular step of the tutorial, a option list is created that determines how a list is sorted (Alphabetically, by age). I tweaked the code to dynamically generate these sorting options from the data set. Essentiall...

After reading some texts regarding creation of files under python, i decided to create this class which creates a new file on a directory, and creating a backup on the other directory if the file already exists (and if it's older than x hours ) The main reason i opened this question is to know i...

I am trying to learn a bit of the language (Haskell) but I am having some problems with understanding how to make programs with pow*. For example I have to create the following program: Input an integer number n and output the sum: 1+2*2*+3*2*+...+n* 2. Use input validation for n to be positive...

I have 3 dependent picklists so that Category picklist values depend on Group values and SubCategory values depend on Category. What is a good way to define the structure in Javascript that would describe these dependencies? and why? I have tree variants. //1 var myStruct = { ...

I've heard that Lbl and Goto use up memory that they don't give back. I've noticed clearing the RAM on my calculator frees up a lot of space and makes my programs run a lot faster. Any suggestions on how to minimize memory leaks here would be greatly appreciated. (This code does function correctl...

Below is a pretty simple Python script to ingest some data, massage it as necessary, append a column, sort it, and then write it back to another file. Still learning all the Python best practices and APIs, so as always, any tips and tricks are appreciated! Feel free to be brutal with me if it's...

I just took a stab at creating a library for something I'm dubbing semi-synchronous programming (async + dependencies). It's rather dense, but I'd really appreciate a quick code review to ensure I'm not introducing any race conditions. Feedback on best practices, general improvements is also we...
