  • Manipulating text with grep

    Imagine you have a file (or bunch of files) and you want to search for a specific string or configuration setting within these files. Opening each file individually and trying to find the specific string would be tiresome and probably isn’t the right approach. So what can we use, then?

  • Hiring a technical writer in the age of DevOps

    It's common for enterprises to leave the technical writer's role out of the DevOps discussion. Even the marketing department joins the discussion in some DevOps-first organizations—so why not the writers?

    Our industry doesn't ask enough of its technical writers. Documentation is an afterthought. Companies farm out technical writing to contractors at the end of the project lifecycle. Corners get cut. Likewise, technical writers don't ask enough of their industry. The expectations for the role vary from company to company. Both circumstances lead to technical writers being left out of the DevOps discussion.

    As your organization matures its DevOps practices, it's time to revisit the role of your technical writer.

  • How to port an awk script to Python

    Scripts are potent ways to solve a problem repeatedly, and awk is an excellent language for writing them. It excels at easy text processing in particular, and it can bring you through some complicated rewriting of config files or reformatting file names in a directory.

  • Navigating Python Code with Wing Pro 7 (part 1 of 3)

    Wing Python IDE includes a boatload of features aimed at making it easier to navigate and understand the structure of Python code. Some of these allow for quick navigation between the definition and uses of a symbol. Others provide a convenient index into source code. And still others quickly find and open files or navigate to symbols matching a name fragment.

    [...]

    This tool supports text matching, wildcard, and regular expression searching and automatically updates the search results as files change.

    Searching on Project Files assumes that you have used Add Existing Directory in the Project menu to add your source code to your project. Typically the project should contain the code you are actively working on. Packages that your code uses can be left out of the project, unless you anticipate often wanting to search them with Search in Files.

  • 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.
