    Learn the commands to install SQLite Database server on Ubuntu 20.04, 18.04, or 21.04 for creating and managing Databases using it.

    What is SQLite?

    In spite of the many options available for database systems, SQLite is the standard and most simple system. This free, compact, and command-line database program allows you to share data easily with others and save it in a simple format. It is a widely used database application in computers, smartphones, and other everyday applications.

    Also, the SQLLite format is used for many desktop applications such as CAD programs, version control systems, record-keeping tools, financial analysis tools, media catalogs, and so forth.

    This type of database engine is sometimes called an embedded database as well since you can run it as a part of another program. SQLite becomes even more powerful with the SQLite browser as it is a graphical and completely free software platform for developing and designing SQLite databases. These codes are free to use for private and commercial purposes because SQLite is part of the public domain.

    Installing SQLite can be an easy task, but it requires correct knowledge. That’s why we have written this tutorial to give you in-depth details on installing and using SQLite on Ubuntu 20.04.

  • How to access and manage RHEL within Red Hat Satellite | Enable Sysadmin

    If you use Red Hat Satellite to manage your infrastructure, you probably occasionally run into situations where you need to access Red Hat Enterprise Linux (RHEL) systems to gather information directly, make changes to systems, review log files, analyze performance metrics, troubleshoot issues, and more.

    Previously, if you were in the Satellite web interface and needed to drill down to a specific RHEL system to complete a task, you would generally need to open a secure shell (SSH) client application, establish an SSH connection, and authenticate to the host. Once you were logged in over SSH, you could run the necessary commands on the host.

  • What is EFS (Elastic File System) in AWS and how to use it [Ed: Proprietary vendor lock-in is something to be avoided, not advertised]

    Amazon Elastic File System(EFS) provides an NFS file system for use with AWS Cloud services and on-premises resources which is simple, scalable, fully managed. We can mount this file system either on AWS Cloud or our on-premises servers. It is built to scale on-demand, grows and shrinks automatically. This means it can grow and reduce its capacity as we add or delete files on it. It is an alternative to our legacy NFS Server.
    Amazon EFS can be quickly and easily created from the Web Console of AWS. This service manages the infrastructure for us, which means we can avoid the complexity of deploying, patching, and maintaining complex file system configurations.
    Amazon EFS supports the Network File System version 4 (NFSv4.1 and NFSv4.0) protocol.

  • Sudo 1.9.8: intercepting commands • Sudo Blog

The intercept option brings this one step further: you can prevent sub-commands from even running.

  • Linux Fu: Globs Vs Regexp | Hackaday

    I once asked a software developer at work how many times we called fork() in our code. I’ll admit, it was a very large project, but I expected the answer to be — at most — two digits. The developer came back and read off some number from a piece of paper that was in the millions. I told them there was no way we had millions of calls to fork() and, of course, we didn’t. The problem was the developer wasn’t clear on the difference between a regular expression and a glob.

    Tools like grep use regular expressions to create search patterns. I might write [Hh]ack ?a ?[Dd]ay as a regular expression to match things like “HackaDay” and “Hack a day” and, even, “Hackaday” using a tool like grep, awk, or many programming languages.

  • How To Suspend A Process And Resume It Later In Linux - OSTechNix [Ed: Old but updated today]

    Picture this scenario. You run a program. But, you don't know how long it will take to finish. The process keeps running several minutes. You can't wait that much longer, because some other important programs are waiting in the queue. Have you ever been in a situation like this? No worries! I just found a simple trick to suspend a process and resume it later in Linux.

    What I am going to do is just pause the currently running process, do some other important tasks, and then resume the stopped process after all other processes are completed. This can be very useful when you have less RAM or Processor to do multi-task. You can pause the running processes at any time, and resume them later, without having to start them all over again. Now let us go ahead and learn to suspend or pause a running process and resume it later in Linux and Unix-like operating systems.

  • 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.
