Extract filename and extension in Bash
...
First, get file name without the path:
filename=$(basename -- "$fullfile")
extension="${filename##*.}"
filename="${filename%.*}"
Alternatively, you can focus on the last '/' of the path instead of the '.' which should work even if you have unpredictable file extensions:

Initial bytes incorrect after Java AES/CBC decryption
...g this work due to missing some information like, forgetting to convert to Base64, initialization vectors, character set, etc. So I thought of making a fully functional code.
Hope this will be useful to you all:
To compile you need additional Apache Commons Codec jar, which is available here:

ArrayBuffer to base64 encoded string
I need an efficient (read native) way to convert an ArrayBuffer to a base64 string which needs to be used on a multipart post.

Regular cast vs. static_cast vs. dynamic_cast [duplicate]

Abstract functions in Swift Language
...cept of abstract in Swift (like Objective-C) but you can do this :
class BaseClass {
func abstractFunction() {
preconditionFailure("This method must be overridden")
}
}
class SubClass : BaseClass {
override func abstractFunction() {
// Override
}
}

Encoding an image file with base64
I want to encode an image into a string using the base64 module. I've ran into a problem though. How do I specify the image I want to be encoded? I tried using the directory to the image, but that simply leads to the directory being encoded. I want the actual image file to be encoded.

Why does an overridden function in the derived class hide other overloads of the base class?
... drastic shift in overload resolution results.
For example, let's say the base class B has a member function foo that takes a parameter of type void *, and all calls to foo(NULL) are resolved to B::foo(void *). Let's say there's no name hiding and this B::foo(void *) is visible in many different cl...

Convert from any classic base to any base in C#
String number = "100";
int fromBase = 16;
int toBase = 10;
String result = Convert.ToString(Convert.ToInt32(number, fromBase), toBase);
// result == "256"
Supported bases are 2, 8, 10 and 16
