I'd like to make sure error details are never sent out in responses from my restify-powered API. The best way to achieve that seemed to be via wrapping server.formatters in another function which filtered-out Errors before passing the transformed body on to the relevant formatter. I've probably m...
So I decided to give a try and learn Julia for doing scientific computing, and I decided to tackle the problem of finding
$$ \int_{D_{\frac{1}{4}}} x^4 + y^2 dA $$
where \$ D_{\frac{1}{4}} \$ is the part of the unit circle in the first cuadrant.
My code in Julia is the following:
using Distr...
Write a program that prompts the user to enter the number of students, the students’ IDs, first names,
and their scores. Then print the average score, the 2 students with the highest scores, the 2 students
with the lowest scores, and all the students that have scores above the average score. ...
An exercise from my computer programming class, this program reads in student scores and displays the total points earned along with a grade. I am tasked with modifying it to ask the user for confirmation when a score higher than 100 is entered. Plainly, it should not add a score greater than 100...
I have a Windows program that prompts the user to input a file path, and file name. I then check that the file exists with Directory.Exists.
Then the user inputs a filename. I check it using this answer to check whether the filename is valid or not(it may or may not yet exist).
Here is my code...
I am trying to write a simplified ArrayList
of integers in C code. With implementation of functions in ArrayList.h. Doubling the size of the array whenever you try to
add to a full array. And being able to set size of starting Array from user input.
Code that I have now which throws error : in...
Given a 2d array, the problem is to find the largest sum, where each subsequent is >= the previous digit but < all of the 'neighbour' digits. You can only move up, down, left and right.
My solution will run in O(NM) time with O(NM) space (please correct me if I'm wrong).
The solution is as foll...
I have implemented an Array class using templates. I have used a std::allocator object for memory allocation. Will it be better to use operator new along with placement new for memory allocation?

This is my first app i have made after learning programming on iOS.
Most of the app is complete just the UI and some features are left to be added.
Any optimizations and coding practices would be very helpful.
The code can be found here: https://github.com/shrijitsingh99/accomplish.git
I have written a code to find whether the path exists between source and destination in a directed graph. I have used BFS and instead of ArrayList or queue, I have written my own helper class.

I started writing a script to handle my file downloads in osx because they quickly pile up and it gets time consuming to do this manually by drag and drop. I am looking forward to get some feedback.

I'm very new to C++ and Arduino, with a background in Python. I've written this code for a countdown timer and a simple menu to set the time available to each player, using button handling code from here.
It works as expected, but I don't know whether this is good idiomatic C++/Arduino code or i...

I've implemented a BackgroundWorker in my WPF app. My code is pretty ugly though. I've been told to write as little as redundant code as possible. IS there some generic Method I could employ to reduce the amount of code?

Soo... I recently read a meta-post about the inherent problems of reputation. It listed some things like:

I have some serious misgivings about how good/idiomatic Clojure code this is. I have a very Haskell-ish implementation that runs very slowly, that I'm happy with, but this optimized version seems really clunky to me, although it runs ~20x faster.

In an effort to learn C# / improve my coding skills, I've started working on the Project Euler problems. After finishing problem 7, I see that I may have been overthinking things a bit, but even so I believe that my solution should be faster than what is presented in the problem overview. While ...

The problem is iterating through the ResultSet of entries takes 1.5 seconds for 10,000 entries. This is the typical code:

Go to riddles.gq and click on "archer". This game is for a math project. Is there anything else I should add or change before I turn it in?
As an exercise, I limited my self to the man pages. I didn't look for a previous existing implementation because I wanted to see how well I could do on my own. I also tried to handle as many cases as I could think of. I am sure there are weaknesses so feel free to point them out. Where can I impr...
