  • Phillips 66 reduces costs and increases agility with SUSE

    How does one of the largest oil producers in the world mitigate a global pandemic that completely wipes out global demand? That was precisely the situation American oil giant Phillips 66 was faced with when Coronavirus first emerged in late 2019.

    For the first time in history, crude oil prices fell below zero, throwing this often volatile market into a new level of uncertainty. Oil production facilities, unable to cease operations, were filling up storage tanks faster than expected demand, forcing them pay buyers to take oil off their hands.

  • Cintiq or Intuos? ...or both? The tablets I use. - David Revoy

    I'm showing my usage of two different tablets to answer the classic "What tablet are you using?". I also do that because I'm tired about the numbered videos "Intuos VS Cintiq" as if you had to choose one clan over the other... Both have pros and cons and with a sane operating system (like my Kubuntu Linux 20.04) you can unplug one on the fly and use the other without too much magnetic noises and a get plug'n'play experience. It really helps, I don't even need to restart Krita. For more information about my tablets, read this blog post where I detail all the one I owned over the last 20 years: https://www.davidrevoy.com/article332/tablet-history-log

  • The Apache Software Foundation Announces Apache® Daffodil™ as a Top-Level Project

    The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of more than 350 Open Source projects and initiatives, announced today Apache® Daffodil™ as a Top-Level Project (TLP).

    Apache Daffodil is an Open Source implementation of the Data Format Description Language 1.0 specification (DFDL; the Open Grid Forum open standard framework for describing the attributes of any data format [1]) to enable universal data interchange. The project was first created at the University of Illinois National Center for Supercomputing Applications (NCSA) in 2009, and entered the Apache Incubator in August 2017.

    "We're extremely excited that Apache Daffodil has achieved this important milestone in its development. The Daffodil DFDL implementation is a game changer in complex text and binary data interfaces and creates massive opportunities for organizations to easily implement highly sophisticated processes like data decomposition, inspection, and reassembly," said Michael Beckerle, Vice President of Apache Daffodil. "Instead of spending a lot of time worrying about how to deal with so many kinds of data that you need to take in, from day one you can convert all sorts of data into XML, or JSON, or your preferred data structure, and convert back if you need to write data out in its original format."

  • Privacy-Focused Brave Browser Plans to Challenge Google With A Private Search Engine

    Brave Browser has been quite impressive with its constant developments for privacy-focused users as a Google Chrome alternative.

    No wonder why Google could be locking down Chrome to resist the rise of Chromium-based browsers.

    Recently, they announced their acquisition of an open-source search engine ‘Tailcat’ by the ex-Devs of Cliqz and shared plans to utilize it to introduce a private Google search alternative.

    Yes, we may have several privacy-focused Google search alternatives already. However, with Brave Search, it could be a proper alternative to the offering of Google Chrome + Google Search.

    Let me highlight a few details that you might want to know about Brave Search.

  • Screenshots suck. But they’re about to get a lot smarter

    Screenshots are ubiquitous. From shopping references to memes and from saving cat photos to serious research, they’re a routine and important quality-of-life feature on computers and mobile devices everywhere.

    Android 12 should finally get full-page website screenshots, if Google can iron the bugs out before release. Samsung and Apple have had that feature for a while, but their recent patents show an interest in capturing metadata, from live links to site-specific information like street addresses and song titles.

    Tap Scroll Capture when you screenshot a Samsung Galaxy, and the phone’s screenshot tool will stitch together a long screenshot to capture an entire website. Browse your screenshots in the Gallery, and you’ll see a Go To Website shortcut, a feature introduced in 2017.

  • Security updates for Thursday [LWN.net]

    Security updates have been issued by Fedora (389-ds-base, dogtag-pki, freeipa, isync, pki-core, and screen), Mageia (firefox, kernel, kernel-linus, libtiff, nonfree-firmware, and thunderbird), Red Hat (bind and java-1.8.0-ibm), Scientific Linux (grub2), and SUSE (kernel-firmware, openldap2, postgresql12, and python-cryptography).

  • Positive Technologies Researcher Discovers And Fixes Linux Kernel Vulnerabilities

    Positive Technologies security researcher Alexander Popov has discovered and fixed five similar issues in the virtual socket implementation of the Linux kernel.

    These vulnerabilities could be exploited for local privilege escalation, as confirmed by Popov in experiments on Fedora 33 Server. The vulnerabilities, known together as CVE-2021-26708, have received a CVSS v3 base score of 7.0 (high severity).

    [...]

    Popov said: “I successfully developed a prototype exploit for local privilege escalation on Fedora 33 Server, bypassing x86_64 platform protections such as SMEP and SMAP. This research will lead to new ideas on how to improve Linux kernel security.”

  • Most Reliable Hosting Company Sites in February 2021 [Ed: 9 out of 10 are GNU/Linux-powered]

    Choopa.com took the top spot as the most reliable hosting company site in February. The top five hosting company sites all had no failed requests during the month, with the ranking decided by fastest average connection time. Choopa.com had the fastest connection time out of all of the top 10 hosting company websites, at just 5ms. In the past 12 months Choopa.com appeared in the top 10 nine times.

  • LinuxLinks – The Home of Linux

    Over the years, we’ve written an enormous range of articles showcasing the finest free and open source Linux software. There’s other computer related areas that we also regularly dive into such as programming, hardware, Android, and more.

    Many of these articles are published in a series. It therefore makes sense to collate all of these series into a central location.

  • 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.
