  • Debian LTS work, June 2018

    I was assigned 15 hours of work by Freexian's Debian LTS initiative and worked 12 hours, so I have carried 3 hours over to July. Since Debian 7 "wheezy" LTS ended at the end of May, I prepared for Debian 8 "jessie" to enter LTS status.

    I prepared a stable update of Linux 3.16, sent it out for review, and then released it. I rebased jessie's linux package on this, but didn't yet upload it.

  • Graphical environments in the world of IoT

    The IoT promises to bring about a revolution in the way we interact with devices around us. While many IoT devices will be hidden away, from sensors that measure manufacturing tolerances in a factory to hubs that control lighting around the home, there are a class of devices that need to provide some sort of graphical output or display to the user. Some examples include digital signage, interactive kiosks, automotive in-car entertainment gateways, smart meters, and the plethora of display screens seen on everything from washing machines to smart thermostats. All of these examples need some way to output graphics to a screen display but in an embedded environment that is not always easy.

    Linux is one of the most popular OS choices for manufacturers and solution providers to use in IoT devices and with it there are a few options available for graphical environments. From custom software to drive the display, through direct frame buffer access with toolkits such as QT, to a full X windowing server. All of these options have their pros and cons and often it is a trade-off between custom software and off-the-shelf components to speed up development. Custom software takes time and requires developers to continue to maintain a code base for the lifetime of the device, while using a graphical toolkit such as QT requires less code but comes with commercial licencing. The open source X windowing server is a popular choice but, being over 30 years old, has some shortcomings. It has been well documented that the design of X windows, although revolutionary at the time, has some security risks especially around application isolation and privilege escalation which has led to efforts to replace it by redesigning the graphical server from the ground up. One such effort is Mir.

  • Canonical releases new infographic to show how Ubuntu Linux 'connects everything'

    To highlight the ubiquitous nature of Ubuntu in particular, Canonical today releases an all-new infographic showing how this distribution "connects everything." I urge you to give it a look, as it will open your eyes to just how important Ubuntu -- and Linux overall -- really is.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. 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.

  • 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.
