  • Ubuntu Blog: Code the future together using Ubuntu

    Described by the organisers as an event made by developers for developers, CodeMotion is an event that we love to attend. In November last year, we announced that Ubuntu wanted to code the future of Italy and we joined CodeMotion 2020, with a session about MicroK8s and Kubeflow as the necessary tools to build an environment for any artificial intelligence project. This year, Canonical and Ubuntu will also be present for the Italian event.

  • Simos Xenitellis: How to compile lxd-p2c to migrate physical servers to LXD containers

    The lxd-p2c utility helps you to migrate your physical servers to LXD containers. Dan Mac Donald wrote a tutorial with practical instructions on how to perform such a migration. There has been a recent discussion on compiling lxd-p2c and I am summarizing here.

    You would run lxd-p2c on a physical server that is to be migrated to a LXD container. It is preferable to avoid compiling it on that physical server, but rather use a static binary of the executable. By doing so, the executable would not have any dependencies for the system libraries of the physical server. You would just need to have the correct architecture (such as amd64 or i386).

    You can either compile lxd-p2c statically yourself, or grab a pre-compiled static binary from the output of Github Actions. Select which alternative is suitable for you.

  • Fourty [sic] Years On

    On Christmas day 1981 I awoke with the usual excitement of any 9 year old boy. I clearly remember going downstairs and being told not to go into the lounge because my Dad was busy setting up my main Christmas present. In those days we’d get a main present and some other smaller presents. My parents weren’t well off, we lived in a typical 3 bedroom semi in Southern England and got by as best we could.

    After breakfast in the kitchen we were eventually allowed to go into the lounge to open some presents. What greeted me was the device that propelled me into the world of computing. My parents has bought me a Sinclair ZX81.

    The reason we weren’t allowed into the lounge was because my Dad had got up early to go and set it up, connecting it to the family TV. He spent most of the early morning typing in some code from a manual or magazine (I forget which) so I’d have something to play with right away.

  • 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. 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.
