  • Containers in Research

    Last week, I attended the Docker Containers for Reproducible Research Workshop hosted by the Software Sustainability Institute. Many talks were addressing how containers can be used in a high performance computing (HPC) environment. Since running the Docker daemon requires root privileges, most administrators are reluctant to allow users running Docker containers in a HPC environment. This issue as been addressed by Singularity, which is an alternative conterization technology that does not require root privileges. The nice thing is that Singularity allows importing existing Docker images, which allows you creating a Singularity container from anything that is on Docker Hub. Although I only used Docker so far, Singularity sounds like a nice technology I would like to explore in the future.

    It is common to use the new year date to start new projects or give new directions for old ones. The last one is the case for Cantor.

    Since when I got the maintainer status for Cantor, I was working to improve the community around the software. Because the great plugins systems of Qt, it is easy to write new backends for Cantor, and in fact in last years Cantor reached the number of 11 backends.

  • Fedora 28 Aiming For Secure Thunderbolt 3 Support

    If Fedora developers are successful, Fedora 28 will feature secure and properly supported Thunderbolt 3 device handling out-of-the-box.

    Long story short, Fedora 28 will hopefully be featuring Red Hat's Bolt project for dealing with modern Thunderbolt devices. With Thunderbolt allowing for direct access to the PCI Express bus, it opens the system up to DMA attacks and other vulnerabilities. But under Thunderbolt 3 is support for security levels by which devices can be restricted to only DisplayPort acess, user authorization of devices, and secure access. The Linux kernel changes for dealing with Thunderbolt 3 is in place but the user-space portion is not.

  • 8 Best Android Launchers To Enhance Looks And Performance Of Your Device in 2018

    Android’s dominance over other mobile operating systems is mainly due to the endless customization opportunities it provides to its user base. Launchers are one of the most customizable parts of Android. Android smartphones are inoperable without a launcher, which comprises of your home screen and the catalog of all the apps available on your device. So every device comes with a default launcher pre-installed.

  • This is the new Acer Chromebook 11

    Many people diss Chromebooks because they simply don't understand them. No, Chrome OS -- the operating system that powers these laptops -- is not just a glorified web browser. Actually, the OS is a full Linux distribution that is both extremely secure and easy to use. True, they can be deficient for some tasks, such as video editing and hardcore gaming, but let's be honest -- not everyone has those needs. If everything you do is in a browser -- email, web surfing, social media, YouTube, Netflix, etc. -- there is no reason to run Windows and open yourself up to malware and other bad things. Hell, Chromebooks even have Microsoft Office support these days!

  • 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.
