  • PCLinuxOS Family Member Spotlight: drhadidy

    I got introduced to Linux in the year 2001. I downloaded my first copy of Suse on my IBM Thinkpad. It wasn't easy to install. The CDs and drivers at that time had a lot of issues. So, it was a dual boot install, and mostly I was just updating the install every now and then and was trying to understand more about the system. But I was fascinated by the idea of open source.

    Then I had a very big virus problem at the end of 2006 which destroyed my Windows driven home PC and laptop, my clinic's PC and my Windows mobile phone.

    I decided to shift to Linux and just get rid of Windows forever, especially when I was reading of all the improvements in the development of Linux and how easy it became by then.

    I installed Suse as the only system on my machines. Then I had a problem with the sound card of my LG laptop.

    I started looking around and trying many other distros, until I read about PCLinuxOS. I was amazed by the reviews, and especially how the installation comes out of the box, and how so many people spoke about how their driver problems disappeared when they used PCLinuxOS. I was shocked how Linux people are impressed by its stability.

    I installed PCLinuxOS on my laptop, and my LG laptop started singing. I was really so impressed and happy with the new system, and really didn't need to go back to Windows since that day.

  • Debian Policy call for participation -- September 2019

    There hasn’t been much activity lately, but no shortage of interesting and hopefully-accessible Debian Policy work. Do write to debian-policy@lists.debian.org if you’d like to participate but are struggling to figure out how.

  • The Fridge: Ubuntu Weekly Newsletter Issue 594

    Welcome to the Ubuntu Weekly Newsletter, Issue 594 for the week of August 25 – 31, 2019. The full version of this issue is available here.

  • Fedora Update Weeks 33–34

    The past two weeks have been rather simple, just catching up on the remaining updates from release monitoring, and also those that monitoring missed. I’m also working through some build/test failures for various reasons.

    Most failures are around the Python 3.8 rebuild. Generally, upstreams are aware of the problems, or I could have reported a bug about it. So fixing these involve backporting fixes that are to be in the next releases. For xtl, I’ve un-retired the package, and disabled the failing arches. I’ve given up on hoping someone might figure out the gcc issue, so I’m just leaving the arch-specific bugs (RHBZ#1745840, RHBZ#1745841) as they are.

Games: Songs of Syx, Super Mario 64 and Stadia

  • Fantasy grand strategy city-builder Songs of Syx is out in Early Access

    As one of the most promising indie games this year, Songs of Syx has properly entered Early Access on Steam so you can try your hand at city-building with a grand strategy theme. It's hard to fully grasp the scope of it right now but it's big. You start off as an insignificant colony and build, scheme, and fight your way towards a metropolis and empire. Funded with a successful Kickstarter campaign that ended back in May 2020 with about £23K from over 800 backers. As they said it would, Linux support is wired up and ready right away.

  • You can now play Super Mario 64 natively on Android, no emulator required

    Forget Super Mario 3D All-Stars. You can now play Super Mario 64 on your Android phone without the need for an emulator. The game now has an unofficial native Android port thanks to XDA member VDavid003. In the summer of 2019, Super Mario 64 was successfully decompiled and translated into human-readable C code by a team known simply as a “group of talented individuals.” This code has been available on GitHub for a little over a year at this point, and VDavid003 took this code to create the tools needed to compile the game for Android. [...] VDavid003 has created a repo containing everything needed to compile the game on a Windows or Linux PC, which can then be sideloaded as an APK to an Android device.

  • Stadia pushing more indie games with Stadia Makers, PUBG dropping keyboard and mouse queue

    Google has announced another wave of indie games are confirmed for Stadia, their game streaming service powered by Linux and Vulkan. This is all part of the previously announced Stadia Makers program back in March during their Google for Games Keynote, where Google will directly support smaller teams using the Unity game engine to bring them to Stadia. As a result, another 7 have been announced to release at various dates.

TechNexion Unveils EDM and AXON SoM’s Powered by NXP i.MX8M Plus SoC

The company offers standard support for Ubuntu 20.04 LTS, Linux-built Yocto Project, and Android 10, as well as extended support for FreeRTOS. If it feels like you’ve seen EDM-G-IMX8M-PLUS module before it’s because it should be the one found in the upcoming Wandboard 8MPLUS SBC. There’s will be other development kits based on existing AXON/EDM baseboards including AXON-PI Raspberry Pi-like starter board, or the full-featured AXON-WIZARD and EDM-WIZARD evaluation boards. Marcel vandenHeuvel, TechNexion’s CEO, gives an overview of the AXON i.MX8M Plus modules and baseboard, and shows a Yocto 3.0 Linux demo with dual displays. Read more

Security: AppArmor and SELinux, Linux Security Features and Zero Trust Security Model

  • Technologies for container isolation: A comparison of AppArmor and SELinux

    I researched how containers, virtual machines (VMs), and processes, in general, are separated by different technologies—namely, AppArmor and SELinux. My goal was to compare these solutions for isolation/separation capabilities in the cloud world. Just as a reminder, Red Hat Enterprise Linux uses SELinux technology to separate processes, containers, and VMs. OpenShift also uses this technology. The first option is an isolation technology called AppArmor, which is a very similar technology to SELinux. However, it is not label-based. AppArmor security profiles, which are equivalent to SELinux security policies, look more user-friendly, but that’s because AppArmor is less complicated and controls fewer operations.

  • Kees Cook: security things in Linux v5.7

    Linux v5.7 was released at the end of May. [...] After Silvio Cesare observed some weaknesses in the implementation of CONFIG_SLAB_FREELIST_HARDENED‘s freelist pointer content obfuscation, I improved their bit diffusion, which makes attacks require significantly more memory content exposures to defeat the obfuscation. As part of the conversation, Vitaly Nikolenko pointed out that the freelist pointer’s location made it relatively easy to target too (for either disclosures or overwrites), so I moved it away from the edge of the slab, making it harder to reach through small-sized overflows (which usually target the freelist pointer). As it turns out, there were a few assumptions in the kernel about the location of the freelist pointer, which had to also get cleaned up.

  • Zero Trust Security Model

    The Zero Trust Network, also called Zero Trust Architecture, is a model that was developed in 2010 by the principal analyst John Kindervag. A zero-trust security system helps to protect the enterprise system and improves cybersecurity. [...] The Zero Trust approach depends upon modern technologies and methods to achieve the target of securing an organization. The Zero Trust Model calls for businesses to manipulate micro-segmentation and granular perimeter execution based on users, their whereabouts, and other data or information, to find out whether to believe a user, machine, or application that is trying to seek access to a specific part of the enterprise or organization. Zero Trust also takes care of all other policies, for example, giving users the least access they require to complete the task they want to complete. Creating a Zero Trust environment is not only about putting into practice the separate singular technology associations; it is also about using these and other technologies to impose the idea that no one and nothing should have access until they have proven that they should be trusted. Of course, organizations know that creating a Zero Trust Security Model is not an overnight achievement. Because it is not easy to achieve something so complex in a single night, it can take years to find the most secure, ideal system possible. Many companies are shifting to the cloud security system. These systems have the best options to go to Zero Trust. Now is the time to be ready for a Zero Trust transition. All organizations, either large or small, or should have Zero Trust security systems for their data safety.
