I’ve written a basic implementation of Breakout using Java 8 & Slick (~400 lines of code). Please let me know of any design/OOP improvements that can be made (any improvements in general are welcome, but I’m specifically looking for design & OOP improvements).

I have some code that allows me to enumerate over months in a year. This code is used both in a Web application as well as a standalone exe. Although it doesn't have to be efficient it is used a lot so if there are any improvements that would be great (I haven't done any profiling). It also needs to be thread-safe.

CasperJS doesn't allow continue statement inside a casper.then functions. This was my solution but I'm not happy about it. Is there a better way to achieve this effect?
casper.start();
casper.then(function() {
var current = 1;
var end = 4;
var skip;
for (;current < end;) {

The fourth project, continuing my C++ saga with terrible post names. :P
An approximate value of pi can be calculated using the series given
below:
$$ \pi \approx 4 \left[ 1 - \dfrac{1}{3} + \dfrac{1}{5} - \dfrac{1}{7} +
\dfrac{1}{9} - \cdots + \dfrac{\left( -1\right)^n}{2n + 1} \right] $$

Could anyone provide any constructive criticism? I'm trying to get a jump on data structures before classes start.
One thing is that I should add a copy constructor and assignment operator. Changes made: got rid of using namespace std.
As the code allows users to specify a cap, if they wish, for their stack any ideas o... | stackexchange/codereview |
Because neither sklearn nor Pandas provide a straightforward and complete one-hot encoder, I decided to write one myself. Both Pandas and sklearn do have an encoder with no option to decode, and the sklearn.LabelEncoder that has the decoding only produces that, labels.
Here's the class:

If I have a oneliner in C such as
size_t maxSizeOf(const char *s)
{
return strlen(s) > M_MAX_SIZE ? M_MAX_SIZE : strlen(s);
}
would it be better to have a macro defined such that
#define MAX_SIZE_OF(s) (strlen(s) > M_MAX_SIZE ? M_MAX_SIZE : strlen(s))
or would it be better to have
size_t maxSizeOf(const char ... | stackexchange/codereview |
Is my Application.php class secure for continuing development?
The Application.php acts as a registry for the whole application. I tried not to rewrite already working code that is being pulled from Zend Framework and PhalconPHP, but allow myself to have freedom with using frameworks within my web application.

I just made a small Luhn Checksum validator
Description of Luhn Checksum
Every number in the Integer gets added individually together, but every second digit gets instead doubled and added. If the doubled number is over ten each individual digit gets added.
It works, but is there a way to make it more elegant and maybe... | stackexchange/codereview |
Based on the previous question, I have implemented all suggestions. Also, I worked a bit in this project to improve it.
Summary of improvements:
split the code into multiple files as .hpp and .cpp
removed STL functions
used only one sf::RectangleShape for border instead of std::vector.
I would like to know how I can ... | stackexchange/codereview |
I'm using Microsoft SQL Server 2014 Express.

I wrote the following query to do it:
declare @i int

For taking part in a course, I need to learn some Java. Unfortunately they only teach Java 1.6, so I understand that later versions could simplify the below code a lot, but I have to stick with 1.6 though, at least for the course.
