One of the classic Unix commands, developed way back in 1974 by Ken Thompson, is the Global Regular Expression Print (grep) command. It's so ubiquitous in computing that it's frequently used as a verb ("grepping through a file") and, depending on how geeky your audience, it fits nicely into real-world scenarios, too. (For example, "I'll have to grep my memory banks to recall that information.") In short, grep is a way to search through a file for a specific pattern of characters. read more

When you write a program, your application may need to read from and write to files stored on the user's computer. This is common in situations when you want to load or store configuration options, you need to create log files, or your user wants to save work for later. Every language handles this task a little differently. This article demonstrates how to handle data files with Java. read more

Tracking disk usage information is a day-to-day task of any system administrator. Linux has some built-in utilities that help you find the disk space of your system. In this post, we will show you how to check disk space on Linux using multiple ways.

WebAssembly is a bytecode format that virtually every browser can compile to its host system's machine code. Alongside JavaScript and WebGL, WebAssembly fulfills the demand for porting applications for platform-independent use in the web browser. As a compilation target for C++ and Rust, WebAssembly enables web browsers to execute code at near-native speed. When you talk about a WebAssembly, application, you must distinguish between three states: read more

WebAssembly is a portable execution format that has drawn a lot of interest due to its ability to execute applications in the browser at near-native speed. By its nature, WebAssembly has some special properties and limitations. However, by combining it with other technologies, completely new possibilities arise, especially related to gaming in the browser. This article describes the concepts, possibilities, and limitations of running WebAssembly on Firefox.

You may not have used SCSI this decade, but the old storage interface software is still in Linux and security holes have been found, and fixed, within it.

If you want to learn input and output in C, start by looking at the stdio.h include file. As you might guess from the name, that file defines all the standard ("std") input and output ("io") functions. The first stdio.h function that most people learn is the printf function to print formatted output. Or the puts function to print a simple string. Those are great functions to print information to the user, but if you want to do more than that, you'll need to explore other functions. read more
