  • ARM in the Datacenter

    ARM processors have seen unprecedented growth in the last three years and are now being used in everything from smart watches to Apple's new M1 desktop and laptop systems, but there is one sector where they have yet to take hold: the enterprise market. For years, many of the largest cloud providers have designed computers around ARM chips, and in December 2020, Microsoft said it was joining the fray by designing its own ARM-based chips for Azure and Surface PCs. Now we are seeing technology based on ARM chips float down from the cloud providers and rise up from the consumer market and start to take hold in the datacenter. In this article, I will highlight some different ARM devices and discuss ways that they have made their way into the datacenter.

  • Hacked Codecov uploading script leaked creds for two months

    Scores of projects potentially affected by supply chain attack.
    A malicious alteration to a shell script lay undetected since January this year at software testing coverage report provider Codecov, sparking fears of another significant supply chain attack.

    Forensic analysis shows that an unknown threat actor exploited an error in Codecov's Docker container image creation process, and gained access to the credential that allowed the modification to the company's Bash Uploader script.

    Codecov said a Google Cloud Storage key was accessed starting January 31 this year, and not secured until April 1 US time.

    The script is normally used to upload coverage reports to Codecov, but it was altered to transmit the UNIX shell environment, which can be used to store variables.

    [...]

    The company said it has rotated all credentials, including the key that was captured by the attackers, and set up monitoring and auditing to ensure that the Bash Uploader cannot be compromised like this again.

  • Google plans to tidy up search on Chromebooks

    While the exact categories are still up in the air, we could see the company going for something similar to the Linux distro Ubuntu, which organizes system search results into different categories for applications, files, folders, websites, and more.

  • Linux Desktops in the Cloud with Shells.com [Ed: A lot of YouTube has become paid-for spam and pseudo 'reviews']
  • These guys made me a CUSTOM gaming laptop, running LINUX!

    I received this laptop, which has been custom-made for me by a company called Eurorra. It's a bit of a weird story, and this won't be a traditional laptop review, because... well, you'll see.

  • 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.
