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...
Switch statement fallthrough in C#?
...ts extreme, this goal results in our just writing in assembly, IL, or even raw op-codes, because the easiest compilation is where there is no compilation at all.
Conversely, the more the language expresses the intention of the programmer, rather than the means taken to that end, the more understanda...

What does Ruby have that Python doesn't, and vice versa?
... " + "strings " + "together"). Single-quoted strings are like Python’s r"raw strings".
There are no “new style” and “old style” classes. Just one kind.
You never directly access attributes. With Ruby, it’s all method calls.
Parentheses for method calls are usually optional.
There...
live output from subprocess command
...t, just Python's actual stdout; see demo at end.
An int value. This is a "raw" file descriptor (in POSIX at least). (Side note: PIPE and STDOUT are actually ints internally, but are "impossible" descriptors, -1 and -2.)
A stream—really, any object with a fileno method. Popen will find the descr...
Accessing inactive union member and undefined behavior?

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...

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.
