  • Ubuntu Weekly Newsletter Issue 678

    Welcome to the Ubuntu Weekly Newsletter, Issue 678 for the week of April 4 – 10, 2021.

  • Ubuntu Blog: Design and Web team summary – 12 April 2021

    The web team at Canonical run two-week iterations building and maintaining all of Canonical websites and product web interfaces. Here are some of the highlights of our completed work from this iteration.

    This iteration has seen many of the team out of the office as schools are out in the UK. This has not limited the exciting new features and developments from the team.

  • Enabling Rapid Decision Making with SUSE Linux Enterprise Server and NVIDIA Virtual GPU (vGPU)
  • SUSECON Digital 2021: a Behind-the-Scenes Look at a Space Oddity | SUSE Communities

    It’s been almost a year since we unveiled SUSECON Digital 2020 – our first virtual SUSECON event. No lies, that event was pulled off in a frenzied whirlwind of pandemic onslaughts, virtual session recordings, and bandwidth battles. Frankly, I was amazed that we met our production schedule in the wake of the Covid-cancellation of our live event in Dublin. And I was even more amazed at our SUSECON audience reaction to the virtual event. You loved it! As one of the first virtual conferences of the Covid era, your feedback told us that we had delivered exactly what was needed at the time. What an exceptional opportunity for us to include thousands of friends from all over the world who normally can’t join us at the big event!

  • Top 3 Linux Server Operating Systems in 2021

    In this article we will look at several Linux distributions, which are an excellent choice if we want to use them as servers. We chose them precisely because they have an excellent level of security, regular patch maintenance and updates, and huge communities. In addition, there are thousands of tutorials on the Internet for every single thing on how to do it and last but not least they are easy to use.

    [...]

    Although we have not put them in the top three, not because they are not unique server operating systems, but because they require more patience, knowledge and time, we must mention FreeBSD, Red Hat, Cent OS and Fedora.

  • Element Keeps conversations in your control

    You are probably using chat applications like Slack, WhatsApp, Discord, Facebook Messenger, Telegram, and another chat app. These are all great to have but in using them you are making a trade-off; you are trading security and privacy for a service that easy to use.

    Matrix is an open standard for communication messages. It is not a server so much as a standard way for clients and servers to talk with each other. The clients and server are open sources. With Matrix, you are not giving your data away to a company that is going to profile you and target advertising at you. This provides a degree of transparency you can look at the code, and you can be confident that it is behaving itself.

    Many developer love Matrix because it let them build on it like Lego bricks and write their clients and servers bots or anything else you can self-host your Matrix server and that means you can create a private community where it knows that your communications are not being intercepted by anybody else. Matrix also has the option for end-to-end encryption, so you know that your messages are private.

    Let’s take a look at a Matrix client known as Element (Riot and Vector) and it is pretty much the reference messaging client.

  • RSS Guard 3.9.2

  • Free Software: Is It Just A Thing Of The Past?

    Free software is an idea that has existed since before the foundation of Linux but has the idea become stuck in the past and is FOSS something that we should move past, this author seems to think so, I disagree though.

  • Linux Foundation Hosts Collaboration Among World’s Largest Insurance Companies

    The Linux Foundation, the nonprofit organization enabling mass innovation through open source, and the American Association of Insurance Services (AAIS), today are announcing the launch of OpenIDL, the Open Insurance Data Link platform and project. The platform will reduce the cost of regulatory reporting for insurance carriers, provide a standardized data repository for analytics and a connection point for third parties to deliver new applications to members.

    openIDL brings together some of the world’s largest insurance companies, including The Hanover and Selective Insurance Group, along with technology and service providers Chainyard, KatRisk and MOBI to advance a common distributed ledger platform for sharing information and business processes across the insurance ecosystem.

    [...]

    “AAIS, and the insurance industry in general, are trailblazers in their contribution and collaboration to these technologies,” said Mike Dolan, senior vice president and general manager of Projects at the Linux Foundation. “Open governance networks like openIDL can now accelerate innovation and development of new product and service offerings for insurance providers and their customers. We’re excited to host this work.”

    As an open source project, all software source code developed will be licensed under an OSI-approved open source license, and all interface specifications developed will be published under an open specification license. And all technical discussions between participants will take place publicly, further enhancing the ability to expand the network to include other participants. As with an openly accessible network, organizations can develop their own proprietary applications and infrastructure integrations.

  • Windows, Ubuntu, Zoom, Safari, MS Exchange Hacked at Pwn2Own 2021

    The 2021 spring edition of Pwn2Own hacking contest concluded last week on April 8 with a three-way tie between Team Devcore, OV, and Computest researchers Daan Keuper and Thijs Alkemade.

    [...]

    The Zoom vulnerabilities exploited by Daan Keuper and Thijs Alkemade of Computest Security are particularly noteworthy because the flaws require no interaction of the victim other than being a participant on a Zoom call. What's more, it affects both Windows and Mac versions of the app, although it's not clear if Android and iOS versions are vulnerable as well.

    Technical details of the flaws are yet to be disclosed, but in a statement sharing the findings, the Dutch security firm said the researchers "were then able to almost completely take over the system and perform actions such as turning on the camera, turning on the microphone, reading emails, checking the screen and downloading the browser history."

  • Security updates for Monday

    Security updates have been issued by CentOS (kernel and libldb), Debian (mediawiki, qemu, ruby-kramdown, and xen), Fedora (grub2, libldb, libopenmpt, python-pikepdf, python39, samba, squid, and webkit2gtk3), openSUSE (bcc, ceph, gssproxy, hostapd, isync, kernel, openexr, openSUSE KMPs, and tpm2-tss-engine), SUSE (fwupdate and wpa_supplicant), and Ubuntu (spamassassin).

  • 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.
