Convert an array of primitive longs into a List of Longs
- by CaptainAwesomePants
This may be a bit of an easy, headesk sort of question, but my first attempt surprisingly completely failed to work. I wanted to take an array of primitive longs and turn it into a list, which I attempted to do like this: long[] input = someAPI.getSomeLongs(); List<Long> = Arrays.asList(input); //Total failure to even compile! What's the right way to do this?Read the article

What is the most popular generic collection data structure library for C?
- by Tom Dalling
I'm looking for a C library that provides generic collection data structures such as lists, associative arrays, sets, etc. The library should be stable and well tested. I'm basically looking for something better than the crappy C standard library. What C libraries fit this description?

Maintaining property lists for xCode projects
- by William Jockusch
My project currently contains two largish property lists. One is currently 20KB; another is 8KB. So far, I have been maintaining them with xCode's property list editor. This is manageable but also a bit clunky. I am wondering if other people have better ways of doing this? So far, my lists consist of nested arrays of strings. The depth is not uniform.Read the article

Are doubles faster than floats in c#?
- by Trap
I'm writing an application which reads large arrays of floats and performs some simple operations with them. I'm using floats because I thought it'd be faster than doubles, but after doing some research I've found that there's some confusion about this topic. Can anyone elaborate on this? Thanks.Read the article

array_key_exists is not working

array_key_exists is not working for large multidimensional array. For ex $arr=array( '1'=>10, '2'=>array('21'=>21, '22'=>22, '23'=>array('test'=>100, '231'=>231), ), '3'=>30, '4'=>40 ); array_key_exists('test',$arr) returns 'false' but it works with some simple arrays.Read the article

How can I find the dimensions of a matrix in Python?
- by PBD10017
How can I find the dimensions of a matrix in Python. Len(A) returns only one variable. Edit: Hi Thanks. close = dataobj.get_data(timestamps, symbols, closefield) Is (I assume) generating a matrix of integers (less likely strings). I need to find the size of that matrix, so I can run some tests without having to iterate through all of the elements. As far as the data type goes, I assume it's an array of arrays (or list of lists).Read the article

Using json_encode on objects in PHP
- by Alan
Hi, I'm trying to output lists of objects as json and would like to know if there's a way to make objects usable to json_encode? The code I've got looks something like $related = $user->getRelatedUsers(); echo json_encode($related); Right now, I'm just iterating through the array of users and individually exporting them into arrays for json_encode to turn into usable json for me. I've already tried making the objects iterable, but json_encode just seems to skip them anyway.Read the article

How to I make a navigation-based app?
- by Dyldo42
Yes, I know, most of you are thinking I'm an idiot, butt (kidding) I'm not. I've been searching everywhere for something on how to fully make a navigation-based iphone app, but all I've found is how to set up table views or navigation controllers. I haven't found anything on how to create a data model (something simple from arrays and dictionaries, SQLite and CoreData are a bit out of my scope) or navigate it. Does anyone know of any tutorials or anything like that? Thanks.Read the article

Getting indices of most recent set of numbers in an array in Matlab?
- by user2539781
Let's say I have an array in Matlab: x = [1 1 1 2 2 2 3 3 3 3 2 2 3 3 3 1 1 1 1 1 2 2 2 2 3 3 3] I want the indices of the most recent set of consecutive '1's. In this case, I want the answer: answer = [16 17 18 19 20] % (which should correspond to the last sequence of 1's) I need an automated way to do this in Matlab, that will work with any size arrays, always giving me the indices for the last set of consecutive 1s. Any suggestions?Read the article
