  • Copy File Contents Into Clipboard Without Displaying Them - OSTechNix

    This guide explains what is Clipboard, and how to copy file contents into Clipboard without displaying the contents of the file using any text viewer applications in Linux.

    What is Clipboard?

    You will definitely cut or copy and paste texts on your system multiple times a day. You may not have remembered how many times you copied something or haven't ever thought about where the copied texts are actually stored. But, you should have copied/cut texts so many times. For those wondering, there is temporary place called "Clipboard" in an operating system. Clipboard is the place where the copied/cut data are kept temporarily.

  • Petter Reinholdtsen: Updated Valutakrambod, now also with information from NBX

    I have neglected the Valutakrambod library for a while, but decided this weekend to give it a face lift. I fixed a few minor glitches in several of the service drivers, where the API had changed since I last looked at the code. I also added support for fetching the order book from the newcomer Norwegian Bitcoin Exchange.

    I alsod decided to migrate the project from github to gitlab in the process. If you want a python library for talking to various currency exchanges, check out code for valutakrambod.

  • Simos Xenitellis: How to run a Windows virtual machine on LXD on Linux

    LXD is a hypervisor to run both system containers (a la LXC) and virtual machines (a la QEMU) on Linux distributions. System containers are lightweight because they are based solely on the Linux kernel for their virtualization features, and support Linux guests only. However, virtual machines can run other operating systems. In this post, we see how to run Windows in a LXD virtual machine.

    The benefit with running Windows through LXD is that you are using the familiar LXD workflow and takes away some of the the complexity from the other ways of running a VM (like virt-manager).

    The content of this tutorial came from https://discuss.linuxcontainers.org/t/running-virtual-machines-with-lxd-4-0/7519 Look towards the end of the thread where Stéphane Graber describes how to simplify the process compared to the instructions at the top of that thread.

    The prerequisite is that you have LXD configured and running.

  • Open source database migration guide: How to transition

    Open source database migration typically involves more than just a database. It is more accurately described as a database ecosystem transition, which can include multiple independent projects for management, monitoring, tuning, connection pooling, high availability and third-party support. Beyond the database ecosystem, application integration with the database may be impacted as well.

    The appeal of open source databases, particularly for smaller non-mission-critical systems, has led to increased adoption and market popularity.

  • Set up your own Slack-like chat system on Linux

    Zulip’s 3.0 release back in July saw over 100 people contribute from all over the world. It also brought support for Ubuntu 20.04, so we fired up our server to see just how easy it is to install and if it could restore our faith in chat. We’re pleased to say it’s super easy and we strongly recommend adding it to your server, too.

    [...]

    The two key bits of terminology to grasp are streams and topics. Streams are a broader hierarchy and can be thought of as separate chatrooms. 

    Different members of your team can be members of different streams, and streams can be made private so that only certain people can see them. Within a stream every message has its own topic and conversations will appear threaded thusly, rather like email subject lines.

    However, unlike email subject lines you can’t be lazy and have a blank thread. This tiny bit of extra effort is what enables everything to be so nicely organised, so that you can enjoy hassle-free open source messaging whether in real time or asynchronously, perhaps catching up on messages from your colleagues in other time zones.

  • 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.
