I'm working on a little project where I have to create sort of an image mask.
Overall my code works quite good but I was wondering if I could increase to performance when repainting my canvas (on mouseover/out).
DEMO
JS:
// Stores all dday objects
var Ddays = {};
// Configuration options
var ...
I've read that I should avoid the postfix increment operator because of performance reasons (in certain cases).
But doesn't this affect code readability? In my opinion:
for(int i = 0; i < 42; i++);
/* i will never equal 42! */
Looks better than:
for(int i = 0; i < 42; ++i);
/* i will...
The current range of iOS devices that support 7.0+ don't include any devices that lack a front-facing camera. I also agree with you that it is unlikely that Apple will release any future devices without the front-facing camera (though not impossible). Even if they do, however, you could and sho...

When I glanced at your code, without even reading it, it looked too complex.
I also do not think an enum is appropriate here. Performance is not an issue for 20 items. If you are worried about concurrency, use an immutable map.
Instead of using enum or map, maybe all the elements you group i...
I have two dictionaries like:
d1= { 'key1': '******', 'key2': '*******'}
d2= { 'key1': ['2', '3'] , 'key2': ['5','6','7']}
And I have to replace the string value '*' in d1 with a '+' in every position indicated by the value in d2 build an expected output like:
d3= { 'key1': '*++***', 'key2'...
Hogwarts is modeled on English private schools like Eton. If Hogwarts is a "private school" where do the students go who either can't afford it or don't get in?
I have a list of lists which represents the options I can chose from.
I have a sequence of indices which represent which option lists I want to take elements from, and in which order.
E.g. if I have
choices = [
[ 1, 2, 3 ],
[ 4, 5, 6 ],
[ 7, 8, 9 ]
]
sequence = [ 2, 0, 1, 1 ]

I recently created one of my first hover effects using html and sass. Since it is my first hover effect, I'm almost positive that is it horribly inefficient. I'm sure there's a way to do this effect using half the number of lines of code, but I can't figure out any ways to do it. The hover eff...
I'm writing an application for work that requires me to process a list of transactions. The list is small (5 records at the most) and I'm required to display that data in an android ListView. My client has asked that I include the ability to order the list based on the date (I have added orderin...
Could you provide feedback for this code? For arrays of length 2, is it more efficient not to use a sorting algorithm?

import java.util.Arrays;

All handler functions must be top level functions on your script. It's not possible to have it inside an object like this.
I'm writing a small application to score matches of a game. (There are two "teams" on each "alliance", and two alliances play each other in a match.) I have a "logic" class that handles the values of different scoring elements for each team, and calculates that team's score.
Instead of writing ...
