I have coded following programs (Bubble, Selection, Insertion) and I want you to review it, Can any one please guide me whether they are correct as most of the programs on internet/books are with Arrays not ArrayList.

List<Integer> unsortedList;

So I'm working on a project that sometimes requires me to switch my server configuration. This is due to some circumstances with database drivers and names that are "too expensive to fix" ...
That made me think though: "Why do I always copy these files around manually?"
Well I decided I won't a...
Below are two functions, one is built with Ramda the other is not. They do the same thing. I was wondering why someone would prefer to use example one over example two.
Example one:
var exists = R.wrap(_.bind(fs.lstatAsync, fs), function(fn, path){
return fn(path).then(R.T, R.F)
})
Example...
See the previous and initial iteration.
I got rid of Run objects and just maintain two integer arrays in the RunHeap: one for starting indices, and another for ending indices. Also, thanks to great suggestion by maaartinus, the algorithm is now stable.
The last, but not least: I do not longer ...
I am currently deciding what programming language I should learn first.
What language would you recommend learning? People have told me to learn python, while others have said learn c first.
Meme: Java vs. JAVA
Originator: Jamal(?) (to be determined)
Cultural Height: The 2nd Monitor (as usual), but also in various comments scattered across meta.
Background: Question with the word JAVA (instead of Java) in the title or body, is often an indication that the poster is a beginner and/...

I've been working on my own dynamically-typed, dynamically-scoped, imperative programming language called Honey Badger and feel that it's reached a stable enough state that I want someone else's eyes on my implementation of the interpreter.
For context, I'm going to walk you through a sample ...
This is the question that prompts this meta: Is my language easy/hard enough? How badly is it designed?.
There was another question a while back, but I can't seem to find it right now...
So, this question is requesting that we review the code for ease of use, but it's not really asking for a r...
If one were to create their own language and documentation for the language, could they ask for a review on code they have written in their language as long as they provided a link or inline documentation?
I have debounce function like var debounced = debounce(my_func, delay);
debounce function makes sure that:
During delay my_func may be executed only once
my_func will be called not earlier that delay ms
So here it's

var scheduled, last_fn;

Recently, I reviewed this question about an LZW decoder. In order to properly review that question, I needed to write my own encoder and decoder to be able to test their program. Someone thought it would be interesting to submit these programs for review, so here they are:

Have one div:
Here's what scrolling of this div should look like:
The only way I see is to duplicate div to left and right sides of original one, and then scroll the whole bunch. Here is a corner-cutting implementation sketch: Fiddle

$original = $("#or...
The code is below. The program downloads stock information from yahoo finance and displays it in the spread sheet. On my mac the program takes 10 minutes to get data for approximately 4000 stocks and on the PC it takes 45 minutes. I wrote another version which copies and pastes the data instead o...
I am started to code in C++ and tried to implement a simple BST data structure. Since at the moment I am learning about the Rule of Three, I tried to implement it in my code. Yet, I realise that my code might be far from efficient. I also doubt whether I've made a right destructor or not.
What a...
Firstly I must say I'm not professional programmer.
Here is my task:

I'm trying to improve my skills with the Task-based Asynchronous Pattern (TAP), by writing simple task-based wrappers around some WMI methods. Here's my first stab at it:

This is for Java 6 and uses Guava.
It's a little ugly and I'm worried I missed some obvious way to do it a lot better.
If there is more than one element satisfying either condition I am saying it's false because the condition I am checking should be unique among the list.

This is a partial update of this question.
To summarize, the class is a generic container similar to MaxHeap, but only needs to support the following operations.

Sorry for this rather lengthy question.

I am having some difficulty compiling a C++ program that I've written.
This program is very simple and, to the best of my knowledge, conforms to all the rules set forth in the C++ Standard. I've read over the entirety of ISO/IEC 14882:2003 twice to be sure.
The program is as follows:
