StackExchange.Redis's profiling features are composed of the IProfiler interface, and the ConnectionMultiplexer.RegisterProfiler(IProfiler), ConnectionMultiplexer.BeginProfiling(object), ConnectionMultiplexer.FinishProfiling(object) methods. Begin and Finish profiling take a context object so tha...

Constructors are methods in a class that are invoked when an instance of that class is created. Their main responsibility is to leave the new object in a useful and consistent state. Destructors/Finalizers are methods in a class that are invoked when an instance of that is destroyed. In C# they are...

Java I/O (Input and Output) is used to process the input and produce the output. Java uses the concept of stream to make I/O operation fast. The java.io package contains all the classes required for input and output operations. Handling files is also done in java by Java I/O API.

This topic illustrates how to avoid adding unwanted files (or file changes) in a Git repo. There are several ways (global or local .gitignore, .git/exclude, git update-index --assume-unchanged, and git update-index --skip-tree), but keep in mind Git is managing content, which means: ignoring actuall...

When it comes to storing, reading, or communicating data, working with the files of an operating system is both necessary and easy with Python. Unlike other languages where file input and output requires complex reading and writing objects, Python simplifies the process only needing commands to open...

In C, some expressions yield undefined behavior. The standard explicitly chooses to not define how a compiler should behave if it encounters such an expression. As a result, a compiler is free to do whatever it sees fit and may produce useful results, unexpected results, or even crash. Code that i...

CSS specificity intends to promote code conciseness by allowing an author to define some general formatting rules for a broad set of elements, and then to override them for a certain subset.

In Node.js, resource intensive operations such as I/O are performed asynchronously, but have a synchronous counterpart (e.g. there exists a fs.readFile and its counterpart is fs.readFileSync). Since Node is single-threaded, you should be careful when using synchronous operations, because they will...

C++ file I/O is done via streams. The key abstractions are: std::istream for reading text. std::ostream for writing text. std::streambuf for reading or writing characters. Formatted input uses operator>>. Formatted output uses operator<<. Streams use std::locale, e.g., for details ...

#include <stdio.h> /* Include this to use any of the following sections */ FILE *fopen(const char *path, const char *mode); /* Open a stream on the file at path with the specified mode */ FILE *freopen(const char *path, const char *mode, FILE *stream); /* Re-open an existing stream on the...
