  • 9 Useful PDF Manipulation Tools

    Portable Document Format (PDF) is a file format created by Adobe Systems in 1993 for document exchange. The format includes a subset of the PostScript page description programming language, a font-embedding system, and a structural storage system.

    Over the years PDF has become an extremely important file format. If you want to create documents that can be viewed under all major operating systems, PDF is the ticket, as it maintains the overall look and feel of documents regardless of what platform they are viewed under.

    There is a large range of PDF-related software available with many different applications available that can both output to and open files. Many open source software save documents to this format such as LibreOffice and GIMP.

    The purpose of this Group Test is to highlight high quality small tools that are designed to manipulate PDF files. We are not considering PDF editors, PDF viewers, tools that add an OCR layer to PDF files here. This is because these categories are covered by other legendary Group Tests.

  • 6 alternatives to OpsGenie for managing monitoring alerts

    Now, if an issue comes up with any of this company's products, the response team should act before the customer (and company) experiences negative effects. There won’t be much of a problem if the response team is immediately there to jump on the issue, but in case they are not, someone from the response team should notify them in some way to reduce the diameter of functional or possible financial losses.

    Here's the problem. People are not able to notice and respond to issues all the time. If you send the response team an email or text message, there is a probability that no one on the team will see it before the issue causes significant financial loss. Also, the response team might already be receiving so many email alerts that even if they are available, they may find it difficult to spot the high-impact issues among the smaller ones. In this situation, you should send someone from the response team a distinct alert, such as making a phone call or messaging a pager. However, if you decide to call, you need to know who is actually available, otherwise you might have to call multiple people until you find the response team member who is ready to jump on a ringing phone at that very moment, which can take even longer if your call is at an odd time for their location.

    Instead, what you need is a tool that not only monitors your systems but also intelligently manages the alert process for the quickest results possible. A popular commercial option is OpsGenie, and in this article, we will talk about open source alternatives to this proprietary option.

  • 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.
