  • How to benchmark your websites with the open source Apache Bench tool

    Every business depends on data. It's how they evolve, improve, pivot, market and grow. The lure of data isn't limited to marketing and suit-type staff. IT also requires data to not only make decisions, but to improve the technology used to make business happen.

    That's why you need all the tools to collect information about your systems—every system. One crucial service you need to know about is your web servers. After all, those web servers are how you sell your products and interact with the public.

    How do you collect data about your websites? One way is to use the Apache Bench tool. Apache Bench is a tool used to load test websites and APIs. I'm going to show you how to install and use this handy tool, so you'll have all the data you require about how your websites are performing.

  • Reynaldo Verdejo: Short tutorial: Digital Television with GStreamer (ATSC setup)

    GStreamer support for Digital Television (DTV) is still working. If you follow a few very simple steps you can get DTV signals tuned-to, captured, decoded and displayed with your computer and a few accessories.

    This short article presents basic instructions for a working DTV setup. I'm going to use ATSC in the US as an example, but these instructions should work equally well for other terrestrial delivery systems and other countries.

    What hardware do you need?

    Beyond a computer, you will need an antenna and a capture device. I recently tested a Hauppauge WinTV-dualHD (ATSC/QAM) USB dongle with a 5-years old Amazon basics flat indoor antenna (that looks pretty much like this one) and it worked quite well at roughly 60km from the repeater station.

    Installation

    The hardware setup is simple. Install the antenna pointing to your repeater station and as high as you can. Your local telecommunications and/or broadcasting association should have data about repeaters near you. You can get this information by ZIP code from the Federal Communications Commission (FCC) if you are in the US.

  • Using Finalizers to Control Deletion | Kubernetes

    Deleting objects in Kubernetes can be challenging. You may think you’ve deleted something, only to find it still persists. While issuing a kubectl delete command and hoping for the best might work for day-to-day operations, understanding how Kubernetes delete commands operate will help you understand why some objects linger after deletion.

  • How to Control Vagrant Box Using Vagrant commands

    In the previous article, we have seen how to spin up a virtual machine using vagrant. In this article, we will focus on customizing the vagrant file according to our requirements and see important commands to work with the vagrant.

  • How to install Essential Multimedia Codecs in Linux

    By default, the Linux system cannot play most video files that are in encrypted formats (proprietary media formats) if you do not have the required Media Codecs installed on your system.

    It contains lots of packages like flash plugin, gstreamer, mp4, libavcodec, etc (especially decoder), which are not open source and some of them involve copyright patent or legal issues. Hence, these are not installed by default nor shipped with official repository.

    If you try to play proprietary media formats without installing media codecs, you will see the following error message “Unable to play the file”.

    In this brief tutorial, we’ll show you how to install Media Codes on Ubuntu, Fedora and openSUSE systems.

  • Ubuntu Install Buku Bookmark Manager From The Terminal

    Buku is a powerful bookmark manager written in Python3 and SQLite3. It’s a flexible command-line solution with a private, portable, merge-able database along with seamless GUI integration.

    It can auto-import bookmarks from your browser(s) or fetch the title and description of a bookmarked URL from the web. You can use your favourite editor to compose and update bookmarks. With multiple search options, including regex and a deep scan mode (particularly for URLs), it can find any bookmark instantly. Buku can look up the latest snapshot of a broken link on the Wayback Machine. There’s an Easter egg to revisit random forgotten bookmarks too! Buku is too busy to track you: no hidden history, obsolete records, usage analytics or homing.

  • 1 Click Google Chrome Install On Ubuntu [ Simple and Easy ]

    As of March 2021, StatCounter estimates that Chrome has a 66% worldwide browser market share (after peaking at 72.38% in November 2018) on personal computers (PC), is also dominant on mobile, and has caught up with Safari on tablets (or about a percent-point below at 42.33%), and at 63.59% across all platforms combined. Because of this success, Google has expanded the “Chrome” brand name to other products: Chrome OS, Chromecast, Chromebook, Chromebit, Chromebox, and Chromebase.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
