This is the first little project I've made that didn't feel it was complete gibberish. But I couldn't tell.
The biggest problem I had with this was using the BoardValue enum working like I wanted to. I understand that classes should have a level of abstraction to them and I suspect that the way I implemented the at(int... | stackexchange/codereview |
Could someone give some feedbacks from perspective of oo design and coding style on the following codes:

After almost completely redoing the first version I think I finally have it. I still have a few things to add/change, but I think it's pretty good and safe. I've improved security features as well as overall functionality.
I haven't run this program through pycharm yet, so there might be a few PEP 8 errors. It took me ... | stackexchange/codereview |
I need to check that a user is allowed to save/retrieve contacts to/from the database by calling a web service, and return an HTTP403 with an explanation if it is not the case.
So for the sake of factorizing the code, I decided to use a boolean method that "never" returns false and is there only to check this, and thro... | stackexchange/codereview |
I have just finished my first true console game using C++. I would love if I could get some feedback on my program, I have a few specific comments in my code that I have questions on and will list a few more that I ran into while building this game.

In a bigger project of mine I'm using angular to create a dropdown menu dynamically and then toggling a dropdown menu for some of the menu items. This is why I got a function that toggles the dropdown menus for only the items that should actually have one. However, I feel like I should try to DRY this out a bit since I... | stackexchange/codereview |
Let me start by saying that I am very happy with this code. I want to share it with other people because I think they will find it helpful, but I want to make sure I did everything in good form before I do so.

I have written my own deque class to get a better grasp of C++ pointers and memory management. The following code is part of a larger 2D isometric game I am developing. It compiles and runs fine using MSVS express 15.
I have provided a unit test source + output. I am fairly sure there are no memory leak issues (using ... | stackexchange/codereview |
Currently building my personal site using Jekyll, inuitcss and GitHub Pages. I'd like to hear your thoughts on the markup of my blog page and its post pages.
What do you think about handling logo's like this? Also I'm not sure about the headings. The page-title probably should be part of the main section.

I'm doing my best to explain how this works, but it's pretty confusing and lengthy. Let me know if there's something I can do to clarify.

This is a follow-up from: Reversing a domain name string in Java
There are a number of ways of splitting a String using a delimiter in Java, especially now with Java 8:
StringTokenizer (not recommended)
String.split (recommended replacement)

Scanner with Pattern

I'm reading/writing half precision floating point numbers in C#. These are basically 16 bit floats, compared to the usual 32/64 bit floats and doubles we are used to working with.
I've taken some highly tested Java code from an obvious "expert on the subject" here and modified it to work with C#. Is this correct?
