  • New release of the Ubuntu-based Pearl, 11

    Pearl Linux OS has been available for free download since 12/2014 with our first release simply titled Pearl Linux. It was based on the 14.04 released version of Ubuntu. That release was using the XFCE desktop environment. Since then we now offer the MATE, GNOME, LXDE and soon to come our own DE PearlDE which will be a mix of LXDE and XFCE4 desktops. As of the latest release Pearl OS 3.0 we are now maintaining our own repository on site. Also all tho far from ready, we are working on the new website. The forum ain't pretty but it is up and running for ya all to post any questions you may have.

New GNU Releases and FSF Spring "Bulletin"

  • June GNU Spotlight with Amin Bandali: Twelve new GNU releases! [Ed: Much respect to Amin Bandali for stepping up and helping the FSF a lot when it needed it the most]
  • Spring "Bulletin": Verifying licenses, free software in education, and more!

    Software freedom needs our advocacy, our words and voices, and our generosity to spread. The biannual Free Software Foundation Bulletin is an item made for sharing, its articles from FSF staff and community members help facilitate the conversation about the importance of free software in daily life. It is a great tool to help people find their reason to support free software, to contribute to free software, or -- for the many who are just learning about it -- to take their next steps up the ladder to freedom.

  • Unravelling complexity in a software-defined vehicles industry | Ubuntu

    Vehicles are becoming more connected, autonomous, shared and electric (the famous CASE acronym). While customers expect new features and upgradability, the software and hardware components enabling such innovations require a different system architecture to function. This is a major change for the automotive industry as it requires new software skills, methodologies and business models. At the same time, automotive manufacturers need to adhere to complex and strict industry standards, and uphold safety-critical functions. In this post, we will focus on the different challenges the industry is facing in terms of hardware and software complexity, cybersecurity and safety. We will also discuss how Original Equipment Manufacturers (OEMs) can learn from software companies to survive this transition towards software-defined vehicles and succeed. [...] On top of this, regulations are becoming very strict, forcing OEMs to provide patches and fixes to common vulnerabilities and exposures (CVE). Taking into account the previously detailed system complexity, it is becoming increasingly necessary to move towards a software-defined holistic context. Only a software-defined approach can provide the required flexibility and scalability that allows companies to comply with regulatory requirements while providing UX updates and handling hardware complexity. Of course, cybersecurity never only relies on software. Hardware vulnerabilities can also occur and usually lead to even worse consequences. Some hardware issues can be patched via software, but usually these CVEs remain valid throughout the system’s lifetime. For example, Meltdown and Spectre, two of the most widespread hardware vulnerabilities in the world, are still present and affecting tons of devices. This means that during hardware conception, cybersecurity must be taken into account in the specifications and system architecture in order to limit these vulnerabilities.
