Can you please review my PHP script below? It is for a contact form. Am I breaking any rules? Does it seem okay to you? <?php session_start(); if ($_SERVER['REQUEST_METHOD'] == 'POST'){ ob_start(); if(isset( $_REQUEST['name'], $_REQUEST['email'], ...

I'm coding something to simulate evolution, but with an equation that is tested to find the digitsum of an algorithm. Basically what it does is that it creates GENERATION Organisms, which have DNABITS ints, and it performs ((dna[0] & i) / i) + ((dna[1] & i) / i)... and then compares that to t...

Is there a faster way to compute the bounding area between 2 points? // Minified Version public static Rectangle computeBounds(Point2D.Double p1, Point2D.Double p2) { double dx = p2.x - p1.x, dy = p2.y - p1.y; return new Rectangle((int) (dx < 0 ? p2.x : p1.x), (int) (dy < 0 ? p2....

My goal is to save space occupied by 2D array(sea) that has 3 different values Ocean sea;//Ocean class has member 'private int[][] oceanMatrix;' public final static int EMPTY = 1; public final static int SHARK = 2; public final static int FISH = 3; by compressing it and place in two one dime...

I am trying to analyize the following bit of code for the outcomes: var supportsHTML5MP4Video = function (){ var detect = document.createElement('video') || false; if(!detect){ return false; } return typeof detect.canPlayType !== "undefined" && (detect.canPlayType("video/mp4") === "maybe" || det...

I have regrettably been away from C programming for a very long time, so I'd like to get a quick code review of a first proof of concept, before I get too far into adding capabilies, using the getopt library for arguments, alternate output and input character sets, a PolarSSL implementation, and ...

The old function was : <?php function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") { $theValue = (!get_magic_quotes_gpc()) ? addslashes($theValue) : $theValue; switch ($theType) { case "text": $theValue = ($theValue != "") ? "'" . $theValue . "'" : "...

I've been reading a lot about repository patterns these days. At first, the pattern seemed easy. Most of the examples I read over the web use an ORM like below. interface MemberRepositoryInterface { public function find($id); } class MemberRepository implements MemberRepositoryInterface { ...

I wrote a function to generate a string of javascript code from a clojure map. The idea is to use it in the creation of an HTML response, so that Javascript on a web page has access to the same application configuration as the back end. Is there a better way to do this? (defn javascript-config ...

in c using sleep would make the program for a short interval of time: sleep(2000);//or whatever the number (in milliseconds) But I really don't want to include unistd.h just to use sleep so I'm doing it this way: for(int i=0; i<=100000000000; i++); <----- note that the loop doesn't do anythi...

This is the C++ code of my implementation of Knuth's algorithm M that produces mixed-radix numbers: #include "visit.h" void algorithmM(vector<int>& m) { m.insert(m.begin(),2); const int n=m.size(); vector<int> a(n,0); M2: visit(false,a); int j=n-1; M4: if (a[j]==m[j]-1) {a[j]=0;...

I am a very beginning in PHP and Design Patterns. I have been studying the amazing Head First Design patterns. So, I have been trying to translate the original to PHP. However, I must be doing things very wrong, because it is not working. Can you help me? <?php interface FlyBehavior{ public...

Hello there :) Code-Source: https://github.com/darkryder/Chess-python I'd made a project using pygame in python around 3 months ago. This was my first big project after I started learning how to program in college. Now I'd like to know just how good my programming syntax and style is. Whethe...

I know there has to be a better and easier way to do what I am trying to do so I’m sorry for my lack of knowledge of programming. I have left comments to explain my thought process. Thank you for your help and input. #include <iostream> #include <vector> using namespace std; struct selection ...

While performing a detailed testing of different binary search algorithms, I have observed a very curious performance lag between the C# and VB.NET versions (whose codes are virtually identical copies). The most curious thing is that this difference disappeared after carrying out various modifica...

I'm trying to solve The Reve Puzzle (trying to get all the disk to the last peg; similar to the towers of hanoi problem.) this is what I've come up with so far. def solve(disk, source, temppeg1, temppeg2, destination): if disk == 1: print((source, destination)) elif disk == 2: ...

Is there a more cleaner approach to this? I'm doing the String calculator Kata posted by Roy Osherove. I generated a string of supported characters I would like to use, if the string passed into my calculator object isn't supported, raise an error. def supported? s = [*(33..46), *(58..64)].map(

I've written some python code to generate a random hexadecimal string using 31 playing cards drawn without replacement (so no card appears more than once). This is sufficient to provide more than 160 random bits, which is considered sufficient for a bitcoin private key. I'm interested to know wh...

I have a sloppy first program I want to learn how to simplify. DSM suggested using dictionary lookups to simplify complex if statements. I will read about that on my own but any advice would be appreciated of course. Overall how can I make this less sloppy and easier to read? The calendar calcul...

I would like to execute code for many views whenever the window is unloaded. For instance, I could have something like this in a view's initialize: initialize: function() { $(window).unload(this.stopListening.bind(this)); } I'm wondering if it would be better to have a manager which aggre...

I have this batch that builds some projects using msbuild. What I want to do is to skip building my-last.proj if any of the above builds fail: my-proj1.proj to my-proj5.proj using environment variables. I'm sure that there is another cleaner way to do this, but so far I just can't figure it out...

Write the program expr, which evaluatesa reverse Polish expression from the command line, where each operator or operand is a separate argument. From example expr 2 3 4 + * There are 4 files: calc.c #include <stdio.h> #include <stdlib.h> #include "calc.h" int main(int argc, char *argv[]...

For practice I decided that I wanted to write an animation class for SpriteSheets. The problem is that a single Sprite can have different widths depending on the action they are drawn to act. A tool called Sprite Sheet Packer creates a Map file documenting the index and bounds of each sprite. Thi...

I have two files. File 1. Has a list of all the dictionary words File 2. Has a list of all prepositions. I want to remove all the prepositions from the dictionary. I want to reduce the number of lines in my code and also make it more elegant, idiomatic and readable. #!/usr/bin/env rub...

I am trying to create an MVC application and create a Model based in information received from a Web Feature Service or a Web Map Service. I really need to create the model because I want to use the data that I receive in DevExpress components. What I would like to know is if I can create a model...

I am trying to implement an AngularJs directive that would count the number of characters entered into a textarea and display it to the user. Note: it will actually become much more complex later on and will become a full-fledged component that will be similar to the js component used by Stacko...

I have the following scenario: The (web-) application is built with Java/Spring. I have several REST-endpoints which deliver data prepared to be consumed by a frontend by datatables.net. Each of this endpoint has a somehow similar signature (sEcho, iDisplayStart, iDisplayLength etc.) which are s...

I have written a script that allows a user to walk around a dungeon pick up gold and once they have picked it all up they can exit the game through an exit. What I am doing now is writing a bot to do the same. So far I have come up with a 'stupid' bot that is based mainly on randomness. The bot ...

I got a random image rotator working by using the following script (demo). But I was told that it is a bad practice to extend Array.prototype. And it does. It conflicts with the chained select box unless I modify the selected box script. So I guess it's better to not use Array.prototype.shuffle ,...
