  • GUADEC 2018 Reminiscences

    This year’s GUADEC in Almería, Spain, was over two months ago, and so here is a long overdue post about it. It was so long ago that I might as well call it a reminiscence! This will be a different kind of post than the ones I’ve done in past years, as plenty of other bloggers have already posted summaries about the talks.

  • Rugged, Linux-ready transportation PC has four SIM slots

    Nexcom’s Apollo Lake based “VTC 6220-BK” in-vehicle PC features triple displays, 2x SATA bays, 3x GbE with optional PoE, Ublox GPS, and 4x mini-PCIe or M.2 slots paired with SIM slots.

    Intel-based in-vehicle computers have been around for a while — here’s a Linux-friendly Kontron model from 2004 -– but over the last year or two the market has picked up considerably. Like many in-vehicle systems, Nexcom’s VTC 6220-BK is not an automotive IVI computer, but like Lanner’s Apollo Lake based V3G and V3S systems, is designed for buses. The rugged VTC 6220-BK straddles the IVI and telematics worlds, offering triple display support for passenger entertainment plus CAN and OBD connections.

  • FreeBSD Desktop – Part 16 – Configuration – Pause Any Application

    After using UNIX for so many years I knew that I could freeze (or pause) any process in the system with kill -17 (SIGSTOP) signal and then unfreeze it with with kill -19 (SIGCONT) signal as I described in the Process Management section of the Ghost in the Shell – Part 2 article. Doing it that way for the desktop applications is PITA to say the least. Can you imagine opening xterm(1) terminal and searching for all Chromium or Firefox processes and then freezing them one by one every time you need it? Me neither.

    Fortunately with introduction of so called X11 helper utilities – like xdotool(1) – it is now possible to implement it in more usable manner.

  • Custom Sustes Malware Infects Linux and IoT Servers Worldwide [Ed: This only impacts poorly-secured and already-cracked servers. The article overstates the risk.]

    The dangerous characteristic is the fact that an estimate of the infected computers cannot be made at this time. The only way to prevent the infiltrations is to strengthen the network security of the Linux and IoT servers exposed in public. It is very possible that further attacks will be carried out with other distribution tactics.

  • 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.
