I wrote a simple ruby program for interacting with one of my temporary AWS S3 using Ruby SDK. Bellow is the program I've written. Since I learnt ruby by myself I need help/suggestion in following the ruby's best practices with OOPs concept.

I moved to python today after doing a little of c++. This works as intended, but I want to know if I should add the if name == "main" statement. Any other improvements?

userName = input("Who are you?")
userAge = input("How old are you?")

This is my second attempt at creating a game. I think I have gotten the basic ideas of state machines and game loops down, but I'm sure there are still a lot of things I can learn.
It is a basic Tic-Tac-Toe game. There is a menu where you can choose to play vs AI or another player. If the player...
if (parseInt(obj[0].actual) > parseInt(obj[0].projected) && parseInt(obj[0].projected) > parseInt(obj[0].le)) {
biggesteClass = 'bar';

I have a series of unit test classes that use various connections to a database. Every test class uses two methods with the JUnit annotations BeforeClass and AfterClass to start and stop the database connections like so:

I decided to write a class to do this for me. I had a lot of methods that needed to be invoked at sporadic intervals, across multiple projects.
The dictionary will eventually be class methods, I just put new Task()... as an example. I'm fairly new to asynchronous programming, so constructive cr...
I am learning CustomView, So I decided to draw some circle and lines using Canvas. I am succeeded in it.
Now trying to make a circle draggable inside it. I have almost done it. But I think onTouchEvent is not quiet good . Give me suggestion to improve. And I want to make the circle only whe...
I am trying to write a bingo board generator. There are 40 possible entries, each board has 5 x 5 cells, and I need 25 boards.
Each board has 12 winning sequences -- 5 rows (H0 to H4), 5 columns (V0 to V4) and 2 diagonals (D0 and D1).
In order to avoid ties, I want to ensure that each sequence ...
This is a JavaScript calculator that uses JQuery and bootstrap. How can I improve the CSS, HTML, JS and the general design?

Given an element of the permutation group, expressed in Cauchy notation, it is often useful to have it expressed in disjoint cycles (for example to apply the permutation to the keys of a dictionary).
The code below provides a possible answer to the problem: how to go from the Cauchy notation to...
when I loose a connection an event gets triggered. This event should initialize a timer that should try to reconnect until the client is back online. I used the StopWatch for this but I think this code might not be the best.

I'm looking at two ways to address the situation when one member variable has or has not be assigned prior to it being used: either checking it using hasattr() or catching the exception when trying to utilize the variable.
Using hasattr():

As a relative newbie to Assembly programming, although I can get my programs to work, I have no idea if they are disastrously constructed or not.
I have created a simple Hex Dump Utility, using x86-64 under Linux, and it works just fine!
I am learning in isolation however, so I have no peers...
lock_guard
The destructor never checks if mtx == nullptr, which will cause problems if lock_guard got default-constructed.
The lock_guard(M&) constructor cannot be noexcept, as lock on a standard library compatible mutex class is allowed to throw.
Any specific reasons why std::lock_guard or s...

Any tips on how I can make this code DRYer? I'm working on becoming a cleaner and less clunky coder overall. If you notice, user_one() and user_two() are mostly the same code, with minor adjustments. perfect_combo also shares some of the same. I feel like there's a way to cut down on the code in...
