I have implemented a simple ring buffer for providing a buffered read from a socket as shown below. I would like to get it reviewed for following things:
Understand where it can be improved, if it has any bugs (I have tested it but I might have missed something) or maybe a code snippet can be ...
This module has a ensure_downloaded function which takes a slice of Urls. It downloads all of the urls to a local downloads folder (if they aren't already downloaded) and returns.

Number of Paths
You’re testing a new driverless car that is located at the Southwest (bottom-left) corner of an n×n grid. The car is supposed to get to the opposite, Northeast (top-right), corner of the grid. Given n, the size of the grid’s axes, write a function numOfPathsToDest that returns th...
It is fairly common for review requests to be for homework or interview practice questions.
For example there's a fairly steady stream of python tic-tac-toe games which I'm basically convinced fall into this category. These tic-tac-toe implementations consistently have certain slightly strange ...
I'm follow this article about "common opponent in tennis", my goal is to script it in the most effecient way. Below you can find my code but is so slow. For calculate the result of 1 match my laptop spent 120seconds more or less, and I have a dataset of 150k of rows to calculate.

I have created a simple neural network for a regression problem (fitting a higher order polynomial) with one input node, one output node and two hidden layers where the number of units in the hidden layers is adaptive.
Here the activation functions of the hidden layers are programmed to be sigmo...
The Karatsuba algorithm, first published in 1962, aims to speed up the multiplication of big numbers by reducing the number of 'single-digit-multiplications' involved.
Because of its complexity (overhead) this method is not particularly fast on the 'smaller' numbers. There's a threshold to be ob...
I have couple of MessageProcessors. One of the Processor will log the payload. Other Processor will save into an embedded database.
Here is the code I have written so far:
I am using annotation-driven configuration so I have omitted other classes which are not used in this use case.

Good evening, recently I discovered this community, and I come here today to try to get some hints to improve my code performance.
I am trying to scrape a web site and save data in a database using sqlite.
Functions nbr_processes_for_links() and get_link(), find all links in one page. To do tha...
I'm currently working in SFML for c++ and trying to resize a window however the solution I found to my problem doesn't quite feel right and I'm looking if there is a better way.
I have an object that gets resized multiple times so it may fit inside the window or not, I have to expand the window ...
Looking to see if there is a simpler way to achieve this. I would love if I could keep the return as a one-line LINQ expression. I want to grab the total number of hints used, which can be more than one.

Im making a program that randomly picks a workout for a certain day according to the system date / day (as in Sunday, Monday, Tuesday etc...)
I'm fairly new to c++. I've stored the workouts in classes and wanted to randomize the classes according to the day, and then randomly select a workout fr...

Overview
The following is a type system of layers (A, B, C, Null) and nodes for a library.
A version that prints colored text for debugging is on github.
Thanks in advance for reviewing this.
Features
The user can create a stack the layers:
The type of a stack can be C<B<A<>>>, B<A> or C<A>
I wrote a simple breakout game in javascript. I was wondering if anyone could give me some advice on improving my code. I wrote somethings a bit oddly so I am more then welcome to criticism (constructive would be preferred however.)
