Hello, I am trying to manage the retrieval of a node in a nested set model table, not through the unique ID, but through the name (a string), and other nodes within the tree under different parents may be called the same way. As far as now I used an unique ID to get nodes inside the nested sets: SELECT node.name, node.lft, node.r...

What I want...

Hello, I am trying to write a predicate that given the following list in Prolog: [[1,a,b],[2,c,d],[[3,e,f],[4,g,h],[5,i,j]],[6,k,l]] will produce the following list: [[6,k,l],[[5,i,j],[4,g,h],[3,e,f]],[2,c,d],[1,a,b]] As you can see I would like to preserve the order of the elements at the lowest level, to produce elements in the ...

I can't make my table with those two functions because I don't know how to merge cells at the begining and at the end. I've been trying many ways but this is driving me crazy. The table I want to make has 9 columns and 3 rows. So, I want the ...

It works well but is very slow in IE7. FireFox and Safari have no big problems with it. Not very good at jQuery I was wondering if I could speed up this by using bette...

Ok guys, we all know there are all lot of typedef/struct questions out there, but I feel this one is a bit of a mind bender. I'm simulating the neighbor interactions of a crystal lattice using strictly C. I have a struct called "ball_struct" which I typedef'ed as just "ball". The struct contains a pointer to a list of ball_structs (sin...
