design a stack such that getMinimum( ) should be O(1)

EDIT: Here's an implementation of Pete's evil scheme. I haven't tested it thoroughly, but I think it's okay :)
using System.Collections.Generic;
public class FastMinStack<T>

private readonly Stack<T> stack = new Stack<T>();

...inalChildItem);
}
_dbContext.SaveChanges();
}
Note: This is not tested. It's assuming that the child item collection is of type ICollection. (I usually have IList and then the code looks a bit different.) I've also stripped away all repository abstractions to keep it simple.

Are class names in CSS selectors case sensitive?
...
Whoa this is exactly the opposite of what my jsfiddle test indicates. There the div and DIV selectors both matched the <div>, but the id and the class name selectors had to be exactly case sensitive. Unless I misunderstood your answer?

Difference between DTO, VO, POJO, JavaBeans?
... is unique - for example currency codes for currency objects are enough to test equality.
A general heuristic is that value objects should be entirely immutable. If you want to change a value object you should replace the object with a new one and not be allowed to update the values of the valu...
Is it safe to remove selected keys from map within a range loop?
...
I was wondering if a memory leak could happen. So I wrote a test program:
package main
import (
log "github.com/Sirupsen/logrus"
"os/signal"
"os"
"math/rand"
"time"
)
func main() {
log.Info("=== START ===")
defer func() { log.Info("=== DONE ===") }()

For this test port 4433 must be unused on your workstation. And better only run this in a secure environment, as it opens port 4433 shortly to the public, which might see foreign connects in a hostile environment.

SVN how to resolve new tree conflicts when file is added on two branches

XFAIL conflict from merge of add over versioned file
This test does a merge which brings a file addition without history onto an
existing versioned file.
This should be a tree conflict on the file of the 'local obstruction, incoming add upon merge' variety. Fixed expectations in r35...
How do pointer to pointers work in C?
...e a pointer to a 2 dimensional array instead.
Why it's dangerous?
void test()

double **a;
int i1 = sizeof(a[0]);//i1 == 4 == sizeof(double*)
double matrix[ROWS][COLUMNS];
int i2 = sizeof(matrix[0]);//i2 == 240 == COLUMNS * sizeof(double)
}
Here is an example of a pointer to a 2 dime...
What is Rack middleware?

Let's test our new JSON server by either curling or visiting the url http://localhost:9292/hello.json and voila:
$ curl http://localhost:9292/hello.json
{ message: "Hello!" }
It works. Great! That's the basis for every web frame...
The difference between fork(), vfork(), exec() and clone()
... (and POSIX.1-2008 removes vfork from the spec entirely). If you happen to test your code on a system that synonymizes them (e.g. most post-4.4 BSDs aside from NetBSD, pre-2.2.0-pre6 Linux kernels, etc.), it may work even if you violate the vfork contract, then explode if you run it elsewhere.
