I have made a game in java that involves two players to fight each other with spaceships. For one player mode, I have programmed a simple AI to avoid allies and asteroids and go straight towards the player. Unfortunately, the game lags quite a bit when there are 3 AIs at once. I think this is bec...

I've recently finished implementing a ring queue based on std::array in C++11. I tried to write the code as if I were going to submit it to the C++ Standard committee to have a RingQueue as part of the standard while keeping the implementation as simple and fast as possible. The code is below. Pl...

I have a script for a countdown function, which is using massive amounts of CPU power on my MBP.
The script is updating the countdown display every second and basically updating all piecharts aswell.

I have a project with lots of ugly code I've written some time ago. Now I'm trying to make it testable and to use TDD for further development. But every time I'm trying to write unit tests for existing code I'm getting stuck. I just don't know how to test my old code. I can't write any little tes...
I'm writing a plugin and want it to have no dependencies.
I create a form and append it to the page, but the code is really long, does anyone have any suggestions to clean it up, perhaps shorten it? I feel like there must be a better way!
Thanks in advance for your help.

After a bit of work, I've changed my code a lot from the previous question:
I was recommended by George Mauer and rofl to make a better structural design, so hopefully this new build is a bit sleeker in design. I will note that my main target is optimal performance. But like Mr. Mauer said, it ...
I am trying to look at a range of values for samples taken with core drilling. Each drilling has a sample for each specific depth. The range is the depth and for each range there is a property value such as
518.6 thru 517.9 0.3
517.9 thru 516.6 0.6
516.6 thru 514.4 0.9

1) Is there anyway to make it secure...
Below is my attempt at providing a type-safe way to combine to use enumeration and bitset together. The resulting class is intended to be use as a set of flags, where each flag is a member of the "user-defined enumeration".
The user must not define any explicit value to the enumeration member.

The standard way to open a file in Python is to use a with ... as ... context manager. By using a with ... as ... context manager, you can ensure that the file is properly closed, and there aren't any memory issues. Here's how you'd do that:
