Go provides two distinct constructors—new, a generic memory allocator returning a zero‑initialized pointer, and make, a specialized initializer that allocates and prepares slices, maps, and channels—explaining why both exist, how they differ, common pitfalls, and the language’s design philosophy of explicit, ready‑to‑use values.
This guide explains Linux software installation, comparing pre‑built binary packages with compiling from source, covering package managers, repository formats, build tools like CMake and make, and the advantages of each approach for stability, customization, and access to the latest features.
Although Linux is often called a Unix‑like system, it differs in several fundamental ways such as the default shell, command‑line option styles, make utility capabilities, C compiler defaults, GNU tool availability, and the trademarked UNIX designation, all of which affect portability and script writing.
This article outlines the fundamental differences between Unix and Linux, covering shell defaults, option styles, make utilities, compiler conventions, GNU versus Linux distinctions, and the trademarked UNIX term, helping developers write portable scripts and build systems across various Unix-like platforms.
This article outlines the fundamental differences between Linux and Unix, covering topics such as the non‑standard Bash shell, the absence of long‑option support in Unix, variations in Make and C compilers, the distinction between GNU and Linux, and the trademarked UNIX name, providing a concise guide for developers navigating these operating systems.
This article explains Go slice fundamentals, covering how to create slices with make, the relationship between length and capacity, the behavior of append, why zero values appear, the automatic growth mechanism, and how to safely copy slices using the copy function, illustrated with code examples and diagrams.
This article explains how to use Makefiles to create custom build commands, define variables, handle recursive targets, incorporate shell output, add conditional checks, and generate help messages, providing practical examples for Go projects and general build automation.
This guide explains how to accelerate software builds on Linux by using make -j for parallel compilation, mounting a tmpfs for faster I/O, leveraging ccache to reuse previous compile results, and employing distcc to distribute compilation across multiple machines.
This guide walks you through obtaining the Linux kernel source, extracting it, configuring options with menuconfig, compiling with make, installing modules and the kernel, updating bootloader entries, and cleaning up, providing practical commands and tips for a successful custom kernel build.
