I wrote my first simple image upload script that allows users to add items to a database along with pictures of said item. My script takes the images uploaded via a form, processes and resizes them and finally saves them to a hard disk, with their file paths added to a database.
While my code is currently working, I ha... |
This is a class to hold an animation and be able to refer to different animations by titles, but it seems like calling draw(Graphics2D g) and update every frame, would, with this implementation, cause a big slowdown with all the list.get(Object obj) calls. Is this a big deal, and if so how should I change the implement... |

Here's how I wrote the Haskell splitAt function:
splitAt' :: Int -> [a] -> ([a], [a])
splitAt' n ys

| otherwise = splitAt'' n ys []
where splitAt'' a (x:xs) acc
| a == 0 = (acc, x:xs)
| null xs = (acc ++ [x], [])

I am running my shell script on machineA which copies the files from machineB and machineC to machineA.
If the file is not there in machineB, then it should be there in machineC for sure. So I will try to copy from machineB first, if it is not there in machineB then I will go to machineC to copy the same files.

I wrote this code, but it feels like it could be a bit more elegant:
Relevant code only:
GameObject newBall;
GameObject pathBall;
if (tag.Equals(pathBallTagName))
{
newBall = other.gameObject;
pathBall = gameObject;
}

{
newBall = gameObject;
pathBall = other.gameObject;
}
