How to Install and Use dig and nslookup Commands in Linux

The dig and nslookup are network administration command-line tools. They are both helpful for network troubleshooting and gathering information related to Domain Name Server (DNS). The “Domain Information Groper” (dig) command is an essential tool for gathering information or interrogating the DNS name servers to troubleshoot DNS issues. The “Name Server Lookup” (nslookup) command is a network administration command-line tool for querying and obtaining crucial mapping information between a domain name and an IP address.

First Look at EndeavourOS ARM on the Raspberry Pi 4

The EndeavourOS team started working on their ARM port for the distribution about two years ago. Until now, installing EndeavourOS on ARM devices required you to write the latest EndeavourOS ISO image on a microSD card, download the EndeavourOS ARM installation script, and then run the text-based installer that had several stages. The previous ARM installer script, which is still available for unsupported devices, was for advanced users, but now anyone can try EndeavourOS on a supported ARM device (Odroid N2/N2+ and Raspberry Pi at the moment of writing this article) thanks to the new ARM installer.

5 Top Free and Open Source Erlang Web Frameworks

One of the types of software that’s important for a web developer is the web framework. A framework “is a code library that makes a developer’s life easier when building reliable, scalable, and maintainable web applications” by providing reusable code or extensions for common operations. By saving development time, developers can concentrate on application logic rather than mundane elements. A web framework offers the developer a choice about how to solve a specific problem. By using a framework, a developer lets the framework control portions of their application. While it’s perfectly possible to code a web application without using a framework, it’s more practical to use one. Erlang is a general-purpose, concurrent, declarative, functional programming language and runtime environment developed by Ericsson, a Swedish multinational provider of communications technology and services. Erlang is dynamically typed and has a pattern matching syntax. The language solves difficult problems inherent in parallel, concurrent environments. It uses sets of parallel supervised processes, not a single sequential process as found in most programming languages. Let’s explore the 5 Erlang web frameworks. For each program we have compiled its own portal page, a full description with an in-depth analysis of its features, together with links to relevant resources.
