I haven't used NPOI and I would believe you have valid reasons for using it (I'll take a wild guess at saying the thing is running on a server that doesn't have Excel installed), but for the record, if my memory isn't failing me if you used Microsoft VSTO / Excel Interop, you could use a plain & ...
Below is my implementation for an interview question of printing a binary tree level by level. I also include some methods for creating a binary tree from a vector in my solution. Thanks in advance.

this time i wrote a program all by my damn self but I just want to make sure I did it right and if anybody has any suggestions to improve it in anyway
a)Define and implement the Die class depicted by the following UML diagram to create an ADT for one die (singular of dice) with faces showing val...
This method finds the smallest positive number that is evenly divisible by all of the numbers from 1 to 20. But I am wondering if there is a better way to test if all iterations of a for loop completed successfully. Because when I put the found boolean outside the for loop it was terminating my w...
This code section is from the main method of my Annual Fuel Use class. The program projects my annual fuel usage based on at least three fill ups of my car.
Here, I am calculating the max and min for distance (which is miles traveled), MPG, and price per gallon. I'd like a general review.

I'm not familiar with Java in particular, but I do understand switch enough from C++.
If you're terminating the loop when n is 0, it looks like you just need to change your default:
default:
n = 0;
break;
I've removed the sum += 0 as it looks unnecessary. You would then no longer nee...
This is in the works, so hopefully beta sites will have their data become available in SEDE within the next few weeks.
I've created a simple NAT library, with four essential functions:
Find the UNPN device (the router in my case).
Get the external IP address.
Add a port forwarding entry.
Delete a port forwarding entry.
Currently, updating an entry in the NAT table will change only the internal client ip add...
I attempted to write a program to find the largest Palindrome in a sentence. Spaces included and case sensitive.
I have written the below program. Can you suggest better ways to do this ?

I've created a module that implements a basic "Document at a time" algorithm for inverted index querying (more background here). There are many algorithm improvements possible, but I'm now interested in feedback on the structure of the Erlang code, specifically:
Unneeded verbosity / code

I'm new to Java and Android. While I've created a project that seems to work, I'd like some opinions on how to make it better.
The app is going to be used as an interval workout timer/music player for Android devices. I know there's a ton of these already, but I thought it'd be a good way to l...
I am trying to use Entity Framework as simple as posible. Use UnitOfWork and Repository patterns seems to be overkill because whole web application will be pretty straightforward. I came with this idea:

I have to create a website in Classic ASP, and I really want to do a clean design so I will try to put everything in Classes and Models to emulate the ViewModel Pattern.
So can you tell me if this approach of creating objects is good because I will use it everywhere

I have a tree of objects.
Object id:0 Object type:0
Object id:1 Object type:0
Object id:3 Object type:0
Object id:2 Object type:0
Object id:4 Object type:0
Object id:5 Object type:0
For each object I have a method that returns its "index" in the tree down to the root item.

I want to write something serious in JavaScript for the first time in my life. Knowing this, I want to do TDD and write unit tests. I have experience in JUnit, but yet, how to structure my project with QUnit (my choice of framework) remains a mystery to me.
I'm thinking something like this:

I'm Pops, a Community Manager at Stack Exchange. As many of you know, one of your moderators recently stepped down for personal reasons. I'm happy to announce that a great new pro tem mod is about to take his place:

I have the following SQL query that computes for every date the week it falls in (a week begins on Sunday and ends on Saturday):
SELECT EntryDate
,CAST(DATEADD(DAY, 1-DATEPART(WEEKDAY, EntryDate), EntryDate) AS DATE) AS 'SundayDate'

This is mostly related to the following two question:
Web application structure review
Shaky on QUnit folder structure
Question 1 was upvoted and answered, question 2 was closed. The difference is that question 1 is about reviewing an existing project structure while question 2 is about helpi...
I'd like to have suggestions about the structure of my web application.

I am having an issue with the following query returning results a bit too slow and I suspect I am missing something basic. My initial guess is the 'CASE' statement is taking too long to process its result on the underlying data. But it could be something in the derived tables as well.

Your question is: Is it good to use a Singleton here?
My answer is: If you can avoid using a singleton, do it! And you answer this yourself: "Of course I can avoid using a singleton if (...)".
Passing a DataWorkItem object to the constructor or some other method is more preferable than using a ...
I'm working on implementing the stochastic gradient descent algorithm for recommender systems (see Funk) using sparse matrices with Scipy.
This is how a first basic implementation looks like:
N = self.model.shape[0] #no of users
M = self.model.shape[1] #no of items
self.p = np.random.rand(N, K)...
