We generate xml schema for our web services. Amongst other details these schema contain the defintion of the complex types consumers of our services pass in. Those complex types can change if our third party suppliers decide they want to add more details but as can be imagined that's something that shouldn't happen on the whim of a d...
I know iPhone development fairly well. From personal experience, how hard would it be for me to get into Android. I am concerned less about code than I am about distribution of my software, given the fragmentation of the Android OS on compatible devices. EDIT: Thanks for all the great input so far. I just have one more point to clarif...
Given two linked lists of integers. I was asked to return a linked list which contains the non-common elements. I know how to do it in O(n^2), any way to do it in O(n)? ...
I'm going to attempt to create an open project which compares the most common MP3 download providers. This will require a user to enter a track/album/artist name i.e. Deadmau5 this will then pull the relevant prices from the API's. I have a few questions that some of you may have encountered before: Should I have one server side page...
I once saw a dismal comparison of Matlab vs Mathematica. As you can see Matlab achieves the same with very little code. It looks highly efficient to an untrained eye, so I ask, what types of projects is Mathematica good for? Are there any scientific research problems that are easier solved with it? or is Matlab better for almost every co...
I just tried the following in vala, and the assertion fails. int[] x = {1,2}; int[] y = {1,2}; assert( x == y ); I suppose Vala compares the memory locations of x and y instead of the content of the arrays. Is there an easy way to compare two arrays without having to loop though them in vala? ...
I have two arrays in php $arrNum = array(1.7, 1.52, 0.01, 0.11); $arrStr = array('1.7', '1.52', '0.01', '0.11'); Note that the second array is the same as the first one, except it has the values as strings. Is it possible for a sorting or max/min operation to return a different result for the second array just because they are strin...
I have a 3D vector class. The private variables are defined: union { struct { double x; double y; double z; }; double data[3]; }; In implementing operator==, which is faster? return this->x == v.x OR return memcmp(this->data, v.data) == 0; ...
hi everyone, i want to compare between two times the first one is getting by the resultset of an sql query like the following: res = req.executeQuery("SELECT SEC_TO_TIME(SUM(TIME_TO_SEC(timespent))) FROM dailytimesheet where trackingdate=CURRENT_DATE and matricule=36;"); res.first(); { retour.append("<td><label style=\"backgro...
I am attempting to catch the last case in a forEach loop, but all cases seem to evaluate to false instead of the last one being true. My code: for(var i in networks){ if (i == (networks.length - 1)){ //do stuff } } What is going wrong? ...
What's the efficient way to check for a null or value for a column in SQL query. Consider a sql table table with integer column column which has an index. @value can be some integer or null ex: 16 or null. Query 1: Note sure, but it seems one should not rely on the short-circuit in SQL. However, below query always works correctly when ...
I'm reading a username and then checking to see if exists in another database table, the problem is whilst the username is the same the case maybe different and is preventing it from finding a match example jsmith and JSmith or JSMITH. How can I fix this? Should I lower the case when writing to the first database or can I alter my code ...
Hello, I am comparing two lists of email addresses in mysql - listA and listB (both of which are views). Originally, I wanted to find all of the email addresses in listA that are not in listB. I successfully accomplished that with: $comparison_query = mysql_query("SELECT DISTINCT email_addresses FROM listA WHERE email_addresses NOT IN ...
I need to find which id numbers are missing inside s.data compared to users. Is there a better(smaller code) way to compare? Thanks ;) if(users.length != undefined) { for(y=0;y<users.length;y++) { var left = true; for(y2=0;y2<s.data.length;y2++) { if(users[y].client_id==s.data[y2].client_i...

I have to check for character sequences like \chapter{Introduction} from the strings read from a file. To do this I have to first check for the occurence of backslash. This is what I did final char[] chars = strLine.toCharArray(); char c; for(int i = 0; i<chars.length; i++ ){ c = chars[i]; if(...
