Consider the code snippet:
uint16_t ave_uint16_4x4_matrix(int xx, int yy, uint16_t **mat) {
register uint32_t tot=0U, xi, yi;
// Sum 4 by 4 square
for(yi=yy; yi < yy+4; yi++) {
for(xi=xx; xi < xx+4; xi++) {
tot += mat[yi][xi];
}
}
tot >>= 4; // BitShift to do quick Gozint...
The existing answers only tell half of the convenience story. The other half of the story, the half that none of the existing answers cover, answers the question Desmond has posted in the comments:
Why would Swift force me to put convenience in front of my initializer just because I need to ...
Particularly for the sake of unit testing, I'm trying to implement an application with a layered architecture. I'm coding in C# and using ASP.NET Web API for the service layer. I'm aiming at a 3-layer architecture:
Service Layer
Business Logic Layer
Data Access Layer

I'm uncomfor...
The code works on my one test case. What do you think about it, can it be simplified?
/*
if the interval list is [[1,5], [10,15], [20,25]]
and you need to insert the interval [12,27],
then your program should return the new list: [[1,5], [10,27]].
*/
var insertInterval = function(insert, in...
I'm using Rails 4.2.5, and I'd like to update existing records with a csv file with two fields: id,category. Where if the category field is blank, it defaults to misc.
Here's an example csv file:
id,category
123-123-123,0
123-123-124,1
123-123-125,
123-123-126,2
So, I've created some tasks, u...
The output of this code is aaa 3. I was wondering why this is the case. Is this because there is no return value on the mystery method? Thanks for the input.
public static void main(String[] args)
{
String[] arr = { "aaa", "bbb", "ccc" };
mystery(arr);
System.out.println...

This code will perform fft using scipy. The phase angle is also found along with the maximums that correlate to a frequency.
My main problem is that some of the frequencies are not found by the getPeaks function, even though they are above the set threshold '...

I'm a beginner to programming (starting with Javascript), and I'm making my own exercises for practice. I successfully completed problem 1 that I created, but need help implementing problem 2. I've been stuck for an hour.

Scenario
Currently filtering through a list of ~3100 rows of data presented to the end-user in the form of an index (think, list of car models).
This is done in such a way that every item is available in a long list to the end-user however they have the possibility to filter down their results...
for example I got string '555abc', need to generate
333012
,333013
,333023
,333213
,333231 and so on.... until all combinations will output.. not allowed to reapeat combinations and letters also, for example 333011 or 333010.
so have to check with if statement 2 times, one that check to generat...
You've got some pretty poor variable names there. For example, what's m2 supposed to mean?
I don't like the fact, that result generates itself. I would rather have two separate classes: one to run a benchmark and one to represent benchmark result. Also calling some Benchmark.Run method makes m...
Following is the code I wrote in R.
project is the data frame. For the purpose of the code, HOUSE.NO is a column of the type character, and NO..OF.FAMILY.MEMBER is another column of the type integer. My aim was to find out the house numbers which repeated, and then find out if the no of family m...
After coming across Douglas Crockford's views on class-free OOP, and doing away with new and this in Javascript I tried defining an object with its own variable and function, and returning it in JSON, as shown below:
var newObj = function (name, lang){
var obj = {
"name":name,

Sometimes, we have to do some fixing to insert a string into an HTML property. Or just to display it.
But not everything is safe! Consider the following example:
document.getElementById('name').innerHTML = prompt('What is your name?');
This allows to introduce HTML vulnerabilities quite eas...
I have built a jQuery category filtration script that calls a WordPress calendar page with a category querystring. This works but I'm wondering if the code can be optimized at all for a smoother experience. I also get an issue that if I click the buttons too quickly, two instances of the calendar...
The method toggle of Element.classList expects a parameter which names a CSS-class.
You can't assign multiple classes at once by using for example an array.
So you have to write something like ...
div.classList.toggle("hidden-element");
div.classList.toggle("border-defs");
div.classList.toggl...
This is some initial feedback, based on your unit tests. If you're going to submit unit tests as part of an interview application, treat them as first class citizens. My personal opinion is that it would be better not to submit unit tests for the work you've done, than to submit unit tests that...

The following piece of code is giving me a massive headache. It only kind of does what I want it to do, which is take an inputted string, and then search the arraylist of book objects by the object's classification (a string) and then return that book object. Currently the code below works as lon...
