I'm currently learning Python and having a great time so far (coming from PHP, I have a feeling of suddenly seeing the light).
At the same time, I'm studying voting algorithms. So, for training purposes, I made this little class which determines the Condorcet winner of a rank voting election (ba...

Many beta-sites suffer with a problem of voting. Code Review is one of them. We at Code Review have realized that it is hard to vote for answers that you're not aware of, therefore some of us (no monkeys named) posts a link to a recent answer every now and then in the chat.
Instead of us posting...
Considering that these three tag can represent off-topic questions, I'll hold off on the prospective burnination until any remaining off-topic questions are found and closed.
I'll update this as well, along with applying status-completed or status-declined.

I have an application that allows the user to place a string of text into a PDF document. I have three different ways that they can do this:
Use a Form Field. Then they have four properties to define:
Provide field name
provide instance of the field
provide an X-axis Offset
provide a Y-axis O...
I am using the jsmn JSON parser (source code) to get some text from a JSON. jsmn stores the data in tokens, but the tokens do not hold any data, they just point to the token boundaries in JSON string instead. For example, jsmn will create tokens like:
Object [0..31]
String [3..7], String [12.....

The overall program I have to do is a simple tax return. Add wages, interest, dividends, and other income. Deduct $2,800 for each dependent.

I have that and that part is good. Now after I get that, I ask ...0
I am currently working on a problem of an online judge (not a contest). However, my code keeps exceeding the TimeLimit, which is only 1 second.

This is pretty decent code. A few things seem noteworthy:
The spacing is inconsistent. This could have happened if size was a boolean isEmpty in a previous incarnation…
There are a lot more opportunities to declare variables to be final than were used.
The documentation inside the methods is a ...

In my game, I need to detect whether any buttons/keys are pressed at all before I try to process any input. This is easy enough for keys since the XNA library provides a GetPressedKeys method on the KeyboardState class:

Is this is good practice to use __ convention while declaring the member variable?

The primary goal of this code is to convert a PDF file to images. I also create a directory under C:/Media based on a combination of the PDF name and current date and insert the uploaded PDF to the same directory as the images for safe keeping.

I personally like the Second option, like you said it is cleaner, easier to read, and looks fairly simple and straight to the point.
I don't see any obvious mistakes in your code.
I can only suggest that you test it vigorously and perhaps check out the option given by @Jignesh Thakker in the c...0
I'm no Scala Pro, but I'll try to give my two cents anyway:
Your decision to "inject the functions" (pass them as parameters) in order to be able to test them resulted in awkward code, and complicated an otherwise simple method.
As for the tests you chose to make of the resulting method, they s...
You seem to be have a few misconceptions, as @rolfl points out.
First, the data structure you have described and illustrated does not fit the definition of a tree. Rather, I would characterize your data structure as a graph of maximum in-degree 2.

An employer that wants to fill a position normally wouldn't rescind an offer. My guess is either:

Your counteroffer was so unreasonable that they would rather continue interviewing more candidate...

This is a calculator I wrote for a student's project,
It still has a problem (one that I know of), where it can't handle inputs of the form '2*2*2...' (more then one '*' or '/' sign). The case '2*2' was solved in hackish ways.
I'd appreciate any remarks or advice on the code and possibly how to...

Q: Write a C program using multiple functions that will calculate the gross pay for a set of employees
Sometimes, the correct answer really is "Nope; it's all good." It makes for a boring answer, but there it is. It doesn't look like you can make this much faster, based on what you've provided.
One thing you might consider is checking the variables to see if the image manipulations are actually...
