A couple of days ago i found a great framework called AForge.NET.
AForge.NET is a C# framework designed for developers and researchers in the fields of Computer Vision and Artificial Intelligence – image processing, neural networks, genetic algorithms, machine learning, robotics, etc.
Sometimes, you’re faced with the problem to cramp as many smaller textures as possible onto a larger texture. Typical cases are lightmaps, which are very small textures with dimensions that usually are not powers of two, or bitmap fonts where you want to try and fit the entire ascii character set onto a texture without wasting much space.
What you need then, is a rectangle packer, an algorithm that arranges as many smaller rectangles on a larger rectangle as can possibly fit.
It is very important to be able to dynamically control the behavior of .NET applications and to keep track of some of the aspects of the application (i.e. how the application is performing, what errors are produced during runtime, how the application performs at peak times, how to dynamically alter the behavior of the application, etc).
This is a very simple question with a not so simple answer…
Forget for a second about .NET.
If someone asks you how much is 1.000025 – 0.000025 your answer will probably be “1″ and correct. An easy question, right ?
Now, let’s go back to .NET and check if our calculations are correct.
Well, this is a nice one. We all familiar with incremental operators, but from what i saw yesterday… well, there is no need to give a developer some tricky assignment so he could find a way to make some bugs.
Once in a while we need to return data from SQL as delimited string of values and not as rows. There are several ways to do that, but personally i like the next one.
As we know we have two ways to set a variable value to an empty string.
We can just set it to empty quotes “” or set it to string.Empty, but what is the difference and is there one at all ?
I’ve noticed that most of the c# developers i’am talking to, know exactly what “public”, “private”, “protected” and “internal” access modifiers mean and how to use them, but when it comes to “protected internal” they start guessing the answer and it’s never the right one.
Unusual software bugs are a class of software bugs that are considered exceptionally difficult to understand and repair. There are several kinds, mostly named after scientists who discovered counterintuitive things.
The following are two simple questions related to C# inheritance.
Please try to give an answer without executing the code, otherwise where is the fun part ?
