I'm refactoring an old gateway and came across the following method:
def apply_limit_and_offset(options)
limit = options[:limit]
offset = options[:offset]
@result = if offset
@result.drop offset
else
@result
end
@result = if limit
@result.first limit
else
@result...
I did the exercise below to practice. Can someone help me to shorten or improve the code in a simple way for a beginner?
The exercise is:
Given 2 int values, return whichever value is nearest to the value 10,
or return 0 in the event of a tie.
public int Closer(int a, int b)
{

I created this responsive jQuery navigation which will re-size when the pixels get < 500 px and display the mobile navigation, although when the browser re-sizes > 500px it runs the widthCheck() function which is supposed to run the jQuery code that returns it to tablet/desktop size, although it ...
Please review my Adjacency matrix.
Since I use std::vector to create the matrix, I would like to store as many nodes as possible. Is it ok to use std::size_t all over the code?
Are using 1 for connected and 0 for not connected a bad idea?
class AdjMatrix {
public:
AdjMatrix(const std::size_t
I'm working on something for my school's laptops that will disable videos/games between 8:00 AM and 3:15 PM. Due to the giant time gap, I will not be waiting to see if the code functions properly or not. What I want to know is if my code will function properly, as I'm not good enough at JavaScrip...
I would like to greatly reduce verbosity of following code fragment.
What I'd like to do:
Reduce number of occurrences of MaterialRangedParam<Value> and MaterialParam<Value>. C++ has typedef. C# doesn't. Is there keyword for own type of a class?
Remove operator !=, operator ==, GetHashCode and...
Let me explain the code. I need to input first number of inputs i need, say 4.
Then i input i inputs say 1,2,3 and 4. My output should be the corresponding prime numbers for example for the above case output will be 2 3 5 7 (1st 2nd 3rd and 4th prime numbers).

I have a very large Python dictionary with around 3500 keys and each key has as value a list of 35 elements.
Now, I have to compute pairwise correlations. For this, I wrote the following code:
res = dict()
for i in myDict:
for j in myDict:
if i > j:
if someFunc(i, j):...
I watched a presentation by Dave Thomas on Elixir where he gave an example problem that he solved using functional programming. He mentioned using Ruby to solve the same problem, but did not show an example. I decided to give it a try. The problem goes something like this:
For a list (Ruby do...
I've been looking around and even here on the site, but I can not find the correct syntax in PDO to update data, such as the data of a user profile.
You could give me a practical example with html form? I know that maybe I ask so much, but I can not make it work.
I enclose what until now have b...
Just for practice, I am writing a tictactoe game in python 3.4. My main goal with it is to make expandable, meaning a possibly larger than 3x3 board, and possibly more than two players. The way my project is arranged looks something like this:

Class Names
I will address a few problems in no particular order.
public class _Newmain extends Canvas {
public class m2
These are both really bad names for classes. In Java the standard is to use PascalCase for class names. So instead of _Newmain you would say NewMain. However, it is most im...
The exercise 1.3 of the book Structure and Interpretation of Computer Programs asks the following:
Exercise 1.3. Define a procedure that takes three numbers as arguments and returns the sum of the squares of the two larger numbers.
My answer is this:
squareTwoLargest(X, Y, Z, R) :-
( X 
void getTopKWords(const map<string, int>& word_map, const unsigned int k) {
priority_queue<pair<string, int> > pq;
for(auto item : word_map) {
pq.push(make_pair(item.first, item.second));
}
for(unsigned int i=0;i<k;i++) {
auto item = pq.top();
pq.pop();
cout << item.first <<
I know there are many ways to do this, however, I wanted to get a quick review on this one function.
I am using pipes, as I am anticipating logging stderr, and potentially adding input in the very near future.

import sys
def run_command(cmd):
p = subprocess.Popen([cmd],
