os.mkdir() creates a directory, wheras os.mknod() creates a new filesystem node (file), so you should change the applicable function calls to that.

Alternatively, (due to os.mknod() not being great cross-platform), you can open a file for writing then immediately close it again, thus creating a blank file:

Here's a close case that works:

If this isn't going to throw an exception then I don't know what is going to.

This is caused by using blocking code within Netty's event loop.

The code over here is making a blocking request 20 times in a row which cause the machine to break. I don't know what data is coming from the client but I would never recommend to do it in this manner.

Barring the undefined behavior which can be easily be fixed, you're seeing the effect of denormal numbers. They're extremely slow (see Why does changing 0.1f to 0 slow down performance by 10x?) so in modern FPUs there are usually denormals-are-zero (DAZ) and flush-to-zero (FTZ) flags to control the denormal behavior. When DAZ is set the denormals will compare equal to zero which is what you observed

Currently you'll need platform-specific code to disable it. Here's how it's done in x86:

For 3D you may turn your array into a tuple set and then Sheetwrite your tuple set

You are generating random value for all i and j except when i==j, which are the diagonal values. Also, all the values of the diagonals will be same. So before returning the grid, you can generate one last random value and put it to the diagonals. Something like this

If I have time tomorrow I will try to implement the following to your code but I can provide you with a working example of how to get mouse collision precision on a rotated rectangle. I had the same struggle with this and finally found a good explanation and code that I was able to get to work. Check out this website

Now for my own implementation I did not use the method on that website to get my vertices. As you'll see in my code I have a function called updateCorners() in my Square class. I also have objects called this.tl.x and this.tl.y (for each corner).

The formulas are what I use to get vertices of a translated and rotated rectangle and the corner objects are what are used to determine collision. From there I used the distance() function (Pythagorean theorem), the triangleArea() function, and then the clickHit() function which I renamed to collision() and changed some things.

Example in the snippet below

you start your loop by defining a running variable 'i'. But all over the loop, you redefine it to be other integers and unrelated objects. Such as in line 83, line 155, and others. It's difficult to understand your intentions from the question. but if I understand correctly, the problem can be solved by changing every 'i' in the loop to a differently named temporary variable. A simpler solution would be to change the 'i' variable at the beginning of the for loop to smth else. I suggest you adopt a habit of using variable names that have meaning and not just single or double letters.

The command defining f defines it as a symbolic function:
