Hi, I did a numeric method as my diploma thesis and coded it in java. It needs a loot of computational time when done adequate. So I looked for an alternative and found BOINC. Unfortunally I didn't have time for doing my method in BOINC, because I'm an aerospace student and not a programmer and I decided to keep my priority on my java p...

Is it a good idea to check for odd/even length of a palindrome number/string? Most snippets I came across don't do this basic test. If length is even, it can't be a palindrome, no? if len(var) % 2 != 0: # could be a palindrome, continue... else: break Or is it just better (i.e faster) to start comparing the first and last numbers...

I need to make a web application and I want to use MVC. However, my Model can't be one of the standard Models -- the data is not stored in a database but instead in an external application accessible only via a API.

I need to include a node content in another node using some kind of placeholder, for example: [node-5663] will be translated to the node's content (body) where node-id matches 5663. The example above is just an example, what I would need is actually something like this: [table-TABLE-ID] where TABLE-ID will be a field I define in the nod...

The compilation goes fine but when trying to run it on the phone, an error saying "The executable was signed with invali...
I've determined an estimate of the size of my Android emulator's screen in pixels, although I think its resolution can be changed to other numbers. Quite frankly though that doesn't eliminate the general problem of not knowing how many pixels on each axis I have to work with on my Android applications in general. The main problem I'm t...

For an Android program, I am having trouble handling key down and key up events, and the problem I am having with them can almost certainly be generalized to any sort of user input event. I am using Lunar Lander as one of my main learning devices as I make my first meaningful program, and I noticed that it was using onKeyDown as an over...

This site does not allow you to specify a B-tree of order 4 (4 pointers and 3 elements), it only lets you specify B-trees with an even numbe...
