  • Announcing KTechLab 0.40.1

    I’m happy to announce KTechLab release version 0.40.1. KTechLab is an IDE for microcontrollers and electronics. In this new release every user-visible functionality is the same as in previous releases, however, the codebase of KTechLab has been updated, so now it is a pure KDELibs4 and Qt4 application and it does not depend anymore on kde3support and qt3support libraries.

    This release should compile and run on systems where kde3support or qt3support libraries are not available.

    In its current state KTechLab’s codebase is ready to be ported to KDE Frameworks 5 (KF5) and Qt5. So a future release of KTechLab could only depend on modern libraries like KF5 and Qt5.

  • dracut problems fixed and a new FAI version

    Before preparing a new FAI release, I had to debug a nasty boot problem in FAI. Booting a FAI CD on a notebooks only hang when no ethernet cable was connected. This was strange, because the automatic installation does not need a network connection and gets all packages from the installation media.

    Since FAI is using dracut (a replacement for initramfs-tools) and we use the kernel cmdline option rd.neednet, dracut only boots if it can set up at least one ethernet device. Without using this option, dracut does not activate the network at all and FAI cannot configure the /etc/network/interface. There's no option to tell dracut just to try to activate network device, but do not rely on being successful. In the end the fix was to edit a dracut script, so dracut does not wait forever for devices to come up. It was just a simple sed -e 's/exit 1/exit 0/'. Nice.

  • ATA/ATAPI Support in fwupd

    A few vendors have been testing the NVMe firmware update code, and so far so good; soon we should have three more storage vendors moving firmware to stable. A couple of vendors also wanted to use the hdparm binary to update SATA hardware that’s not using the NVMe specification.

  • Fwupd Gaining Support For ATA Device Microcode Updates

    Richard Hughes of Red Hat continues on his conquest for improving the Linux firmware updating experience: his latest accomplishment is getting support for microcode updates on ATA/ATAPI drives into Fwupd.

  • The Best Linux Terminal Color Schemes For 2019

    Terminal customization has become a fairly big hobby for Linux users. There are plenty of ways to spice up the Linux terminal and make it look modern and visually appealing. It’s not just for appearances either. A well thought out color scheme can help reduce eye strain and make working in the terminal a much more enjoyable experience.

  • Optimizing Notepad++ on Linux

    I really like Notepad++. I think it's the best, most convenient text editor around, with a simple interface, tons of useful commands and options, and a wealth of lovely plugins, all of which transform a simple text pad into a powerful, flexible document processor. Whether you're working on notes, Web pages or complex software code, Notepad++ does it all. There's only one problem - it's a Windows application.

    In my Slimbook & Kubuntu reports, I remarked on the shortcomings of different text editors in Linux, all of which pushed me to using Notepad++ on Linux, something I tried to avoid. Now, Notepad++ does not run natively on Linux, so I had to use WINE, and this introduced a whole bunch of other complications. HD scaling in Plasma is tricky for WINE software (and in general, for various compatibility reasons), and you need custom tweaks to get a shortcut icon pinned to the Plasma task manager. In this guide, I'd like to highlight a few tricks you can use to make Notepad++ look and behave beautifully in Linux.

  • 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.
