Story Behind Tux Penguin as the Official Linux Mascot

We cannot 100% declare ourselves as complete Linux users or enthusiasts without having boarded the same train with the famed official Linux Mascot, Tux Penguin.

Can Linux Run Video Games?

Linux is a widely used and popular open source operating system that was first released back in 1991. It differs from operating systems like Windows and macOS in that it is open source and it is highly customizable through its use of “distributions”. Distributions or “distros” are basically different versions of Linux that can be installed along with the Linux core software so that users can customize their system to fit their specific need. Some of the more popular Linux distributions are Ubuntu, Debian and Fedora. For many years Linux had the reputation of being a terrible gaming platform and it was believed that users wouldn’t be able to engage in this popular form of entertainment. The main reason for this is that commercially successful games just weren’t being developed for Linux. A few well known video game titles like Doom, Quake and SimCity made it to Linux but for the most part they were overlooked through the 1990’s. However, things have changed a lot since then and there is an every expanding library of popular video games you can play on Linux. [...] There are plenty of Windows games you can run on Linux and no reason why you can’t play as well as you do when using Windows. If you are having trouble leveling up or winning the best loot, consider trying AskBoosters for help with your game. Aside from native Linux games and Windows games there are a huge amount of browser based games that work on any system including Linux. Read more

Security: DFI and Canonical, IBM/Red Hat/CentOS and Oracle, Malware in GitHub

  • Update CentOS Linux for free

    As you may know, in December 2020 IBM/Red Hat announced that CentOS Linux 8 will end in December 2021. Additionally, the updates for CentOS Linux 6 ended on November 30, 2020. If your organization relies on CentOS, you are faced with finding an alternative OS. The lack of regular updates puts these systems at increasing risk for major vulnerabilities with every passing day. A popular solution with minimal disruption is to simply point your CentOS systems to receive updates from Oracle Linux. This can be done anonymously and at no charge to your organization. With Oracle Linux, you can continue to benefit from a similar, stable CentOS alternative. Oracle Linux updates and errata are freely available and can be applied to CentOS or Red Hat Enterprise Linux (RHEL) instances without reinstalling the operating system. Just connect to the Oracle Linux yum server, and follow these instructions. Best of all, your apps continue to run as usual.

  • Malware in open-source web extensions

    Since the original creator has exclusive control over the account for the distribution channel (which is typically the user's only gateway to the program), it logically follows that they are responsible for transferring control to future maintainers, despite the fact that they may only have the copyright on a portion of the software. Additionally, as the distribution-channel account is the property of the project owner, they can sell that account and the accompanying maintainership. After all, while the code of the extension might be owned by its larger community, the distributing account certainly isn't. Such is what occurred for The Great Suspender, which was a Chrome extension on the Web Store that suspends inactive tabs, halting their scripts and releasing most of the resources from memory. In June 2020, Dean Oemcke, the creator and longtime maintainer, decided to move on from the project. He transferred the GitHub repository and the Web Store rights, announcing the change in a GitHub issue that said nothing about the identity of the new maintainer. The announcement even made a concerning mention of a purchase, which raises the question of who would pay money for a free extension, and why. Of course, as the vast majority of the users of The Great Suspender were not interested in its open-source nature, few of them noticed until October, when the new maintainer made a perfectly ordinary release on the Chrome Web Store. Well, perfectly ordinary except for the minor details that the release did not match the contents of the Git repository, was not tagged on GitHub, and lacked a changelog.

What goes into default Debian?

The venerable locate file-finding utility has long been available for Linux systems, though its origins are in the BSD world. It is a generally useful tool, but does have a cost beyond just the disk space it occupies in the filesystem; there is a periodic daemon program (updatedb) that runs to keep the file-name database up to date. As a recent debian-devel discussion shows, though, people have differing ideas of just how important the tool is—and whether it should be part of the default installation of Debian. There are several variants of locate floating around at this point. The original is described in a ;login: article from 1983; a descendant of that code lives on in the GNU Find Utilities alongside find and xargs. After that came Secure Locate (slocate), which checks permissions to only show file names that users have access to, and its functional successor, mlocate, which does the same check but also merges new changes into the existing database, rather than recreating it, for efficiency and filesystem-cache preservation. On many Linux distributions these days, mlocate is the locate of choice. Read more
