I'm writing a small tool that allows to manually protocol dial-in-actions. That means a user can say he dials in to a site or he dials out of a site. (What this means is not important for the sake of this software.) These action are stored as plain JSON text with automatic backups. The communica...

I need to merge two arrays of objects and I know there are many ways to do it but I am just curious what would be the best way to do it.
e.g - I have the following arrays,
array1 :[{ id :1, name : a, class :c1}, {id :2, name :b, class :c2}]
array2 :[{ id:1, score :20}, {id:2, score :30}]

I have implemented a solution to the Potter Kata. Basically, there are 5 different (types of) books, and the buyer gets a discount depending on how many different books he has bought. Multiple instances of the same book (type) don't get a discount.

I was struck with multiple paths to write a test in rspec of controllers.

StringTokenGenerator is an interface (or abstract class) I've created to the specific task of generating a string token of a given character set. It allows appending characters to it and then It can be used to receive a string token. I wrote this for the second version of ExpressGenGen a code gen...
I wrote an HTTP server for the management of scores for users and levels.

there is a specific JSR 275 (javax.measure) with JScience as RI (Reference Implementation). For example converting 100 Miles to kilometers is easy as:

I'm still working on a parser that can parse log entries from a game called HearthStone, the overall idea is that it will read the log file live when the game is running, parses the log file and show interesting and useful data in real time.

I'm creating a simple function to verify whether or not a string is a palindrome, and must use stacks in solving it. Here's my implementation:
bool isPalindrome(string word) {
// #1 determine length
int n = word.size();

The code I have now is currently working, but I'm looking for ways to optimize it, and really, to just get any feedback.

I created a program which recreates the Queen Ann's Lace fractal. However, when the amount of points that are being plotted increases, the points are plotted way slower. Is there any way to make it so that I only add a point, instead of adding a point and repainting all of the others. I've looked...
In my answer to this question, I wrote a new solution. Personally, I would not use a stack, but given that a stack was required, how good is this solution?
bool isPalindrome(string word) {
stack<char> s;
for (int i = 0; i <= word.size() / 2; i++) {
s.push(word[0]);

For my third assignment in CS2, I was given the following:

In a book I read the following:
The 32-bit processors have 2^32 possible addresses, while curent 64-bit processors have a 48-bit address space
My expectation was that if its a 64-bit processor the address space should also be 2^64.
So I was wondering what is the reason for that limitation?
