What is the difference between “JPG” / “JPEG” / “PNG” / “BMP” / “GIF” / “TIFF” Image?
...are generally suited for photographs. It is not suited for illustrations, drawings and text, as compression artifacts from compressing the image will standout. Lossy compression, as its name implies, does not encode all the information of the file, so when it is recovered into an image, it will not ...
What is Common Gateway Interface (CGI)?
...ection against executing incorrect files and/or serving up CGI programs as raw data in case the server gets misconfigured.
Why does Perl always comes in the way.
It doesn't. Perl was just big and popular at the same time as CGI.
I haven't used Perl CGI for years. I was using mod_perl for a l...
The new keyword “auto”; When should it be used to declare a variable type? [duplicate]
...bjects being created, just by looking at the code.
1. Avoid using new and raw-pointers though.
Sometime, the type is so irrelevant that the knowledge of the type is not even needed, such as in expression template; in fact, practically it is impossible to write the type (correctly), in such case...

How do you convert a byte array to a hexadecimal string, and vice versa?
...u need to do these conversion, you tend to do them a lot. If someone needs raw speed, they just run the benchmarks with some appropriate test data in their desired computing environment. Then, tuck that method away into an extension method where you never look its implementation again (e.g., bytes.T...
Should services always return DTOs, or can they also return domain models?
...yer
b) methods on services in the Application Layer accept as input only "raw" input (data values) or object parameters (to reduce parameter count where necessary) defined in that layer. Specifically, application services never accept Domain objects as input.
The Interface Layer uses mapping techn...
How do I get Windows to go as fast as Linux for compiling C++?
...0% of disk partitions is much faster than the rest of the disk in terms of raw transfer time. Narrower partitions also help minimize seek times.
Are you using RAID? If so, you may need to optimize your choice of RAID type (RAID-5 is bad for write-heavy operations like compiling)

Upper Bound Is Not Inclusive
In the following example we create a raw bidimensional array of Color. Each item represents a pixel, indices are from (0, 0) to (imageWidth - 1, imageHeight - 1).
Color[,] pixels = new Color[imageWidth, imageHeight];
for (int x = 0; x <= imageWidth; ++x) {

Java “Virtual Machine” vs. Python “Interpreter” parlance?
... cpu registers
Java: primitive data types
Python: user-defined types
To draw a real-world analogy: LLVM works with atoms, the Java virtual machine
works with molecules, and The Python virtual machine works with materials.
Since everything must eventually decompose into subatomic particles (real

What is The Rule of Three?
...e using a char* and you should be convinced.
As long as you stay away from raw pointer members, the rule of three is unlikely to concern your own code.
