I got annoyed having to do things like string.IsNullOrEmpty(myString) when it seemed as if myString.IsNullOrEmpty() would perfectly suffice. Therefore, I wrote a small, simple library to wrap the static methods of primitives in extension methods.
I don't suppose there is much to critique about t...
I've been working on another timesaver because I really really don't like to type all those validation ifs and exceptions over an over again.
What I came up with this time is a set of validation extensions that make use of expression trees even if very simple ones.
There are three classes. Th...
I am working on a fingerprint matching technique and it takes a lot of computation time to obtain the result. I would like to know if there is any method available to reduce the for loop for the code given below:
[Tdrow,Tdcol]=size(Td);
matchingscore=zeros(Tdrow,Idrow);
rv = bsxfun(@minus,Td(:,3...
I need to transfer purchase order (PO) information from SQL Server into Sage 300 ERP, so using my Linq-to-Sage implementation, I wrote a little console application that connects to a SQL Server database to fetch PO header information, including some metadata telling me whether a purchase order......
I have created a utility class which allows random iteration over an array.
The idea is pretty much a divide and conquer approach.
public static final class RandomIterator<T> implements Iterator<T> {
//recursion stack
private final LinkedList<int[]> offsets = new LinkedList<>();
pr...
I am writing a code for Barabási–Albert(BA) model with specific node and edges.
The algorithm is almost like [1] as follows:
1.Add m<N nodes to G.
2.Connect nodes in G randomly until you get a connected graph.
3.Create a new node i.
4.Pick a node j uniformly at random from the graph G. S...
How would I properly indent this code in PHP (I'm using WordPress)? I'm mostly concerned about how the <button> comes into this equation @ items_wrap.
<?php

wp_nav_menu( array(
'theme_location' => 'primary_navigation',
'container' ...
I want to find the shortest path between two points in the grid, and than mark the path with '+' sign. I found the shortest path using BFS algorithm, but now I'm not sure how can I mark it using better algorithm. So, this is an example:
5 5
1....
.#.#.
.##2.
.#...

should be marked as:

What is the best way to make a unique number from the IP Address and store it in short data type?
String ipAddress = "10.87.145.103";
short hash = hash(asInt(ipAddress.getBytes(StandardCharsets.UTF_8)));
private static int asInt(byte[] addr) {
return (addr[0] & 0xFF) | ((addr[1] & 0xFF) <<...

Consider the following two structs:
pub struct BitVector<S: BitStorage> {
data: Vec<S>,
capacity: usize,
storage_size: usize
}
pub struct BitSlice<'a, S: BitStorage> {
data: &'a [S],
storage_size: usize
}
Where BitStorage is practically a type that is restricted to all uns...
What do you think about the following syntax for some very simple and intensively reusable validations?
Does this:
string name = (SomeText)"Hm…";
mean for you a none-safe cast to none-empty required text? How does it play with C# syntax? So these two should throw:
string name = (SomeText)nu...
