  • Less can filter what it shows to you (a thing I recently learned)

    According to the (or a) less manpage, you can use Ctrl-N instead of '!' if you want, and use Ctrl-R to make the match literal instead of a regular expression. This less feature is sufficiently old and widespread that it's in OpenBSD and NetBSD. Based on the NEWS file and less's historical releases, this was in less 429, released in April of 2009, so it should be in anything that hasn't completely stopped updating its version of less.

    If you use Ubuntu or any other Debian-based Linux distro, you've no doubt read installation instructions telling you to use the APT command, while others have told you to use dpkg.

  • Simple ways to do a service discovery in Linux | FOSS Linux

    Service discovery cannot gain a proper definition without the acknowledgment of an existing computer network. A computer network sets the needed communication protocols for network devices to share the available resources through its network nodes. This sharing of resources involves both network devices and services pre-defined on that network.

    The workaround to the automatic discovery or detection of these network devices and services under a computer network is a viable definition of service discovery. For service discovery under a configured computer network to be complete, it will need the assistance of a network protocol called Service Discovery Protocol (SDP). With these protocols, network users and administrators do not have to rely on their network configuration skillsets to get things going.

    Since service discovery communicates with software agents on a computer network, its communication protocols need to adhere to a common networking language to prevent continuous user intervention whenever the execution of a critical step is needed.

  • Configuring Vim as a Writing Tool - It's FOSS News

    In my first column I spoke about why I moved my writing to Vim – away from the standard tools of modern writers such as word processors (MS Word and their open source equivalents), text editors (Notepad since I’ve been a Windows user until last year), and cloud based storage technology. If you are a writer, I urge you to read that part 1 before continuing here.

    Essentially, I argued that the more devices you use, the more writing tools you’ll need, the more complex the workflow eventually becomes. This is pertinent because I have four devices, including an Android phone, a main daily driver laptop running Linux, and a couple of older laptops, including a Mac, I take when I go outdoors for shoots.

  • Bottles on Linux to run Windows Applications- A GUI interface for Wine

    Wine is the only stable way in the free and open-source world to install Windows 10//7/xp applications on Linux operating system. However, not much user friendly. Thus to make it easy to use and simplify the process of installing Windows apps “Bottles” is here.

    Of course, Linux operating systems in today’s world don’t deprive for applications. There is one almost for each task, yet couldn’t compete with the app database available for Windows. That’s is the reason why many users intermittently are looking for some best and stable way or free software that allows running Windows applications on Unix and Unix-like systems, including GNU / Linux and FreeBSD. And unfortunately, there are no options except WINE.

    However, Wine’s interface has never been particularly friendly because of the command line, especially for those who do not have advanced knowledge of how to configure it. Hence, to mitigate this issue to some extend Bottles comes in, which is nothing more than a simple interface that makes Wine easy to use and also makes available re-implementations like Lutris and Glorious Eggroll.

It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
