Valve has been working to reassure members of its community that it has not yet thrown in the towel on SteamOS and Linux gaming systems that have been hampered over the years due to performance issues, soaring sales on mainstream rival platforms, and generally weak demand. Valve recently withdrew SteamOS machines from its direct online sales portal.

Using most any Arch Linux distro usually involves balancing the desire for hands-on control of the OS against the attraction of convenient installation and maintenance processes. Bluestar Linux is one of the few Arch distros that gets the balancing act right. Bluestar Linux is a GNU/Linux distribution that features up-to-date packages, an impressive range of software, and a live desktop DVD.

Microsoft has released an open source tool that makes it easier for programmers and developers to run Linux on Windows 10. The new tool also helps Linux distribution maintainers bring their distros to the Windows Store to run on Windows 10's WSL. Microsoft developed the project for distribution maintainers and for developers who want to create custom Linux distributions to run on WSL.

ZevenOS' Neptune 5.0, released earlier this month, offers a refreshing take on a classic KDE-based Linux distro. Neptune 5 Refresh replaces version 4.5 and closes a dormant period that had produced no new releases for more than two years. The wait may be worth it for Linux fans who are devoted to the KDE Plasma desktop. Neptune 5 sports an easy-to-use USB installer tool.

LG has announced a plan to release a new open source version of its webOS platform as part of a deal with South Korea's government to encourage startup initiatives. Working with NIPA, the agency responsible for tech sector development, LG plans to solicit proposals from hundreds of startups, and provide logistical and technical support to the most promising candidates.

SpaceChain has teamed with the Arch Mission Foundation to use open source technology to launch an ambitious project involving the storage of large data sets in spacecraft and on other planets. Arch Mission will load large quantities of data onto SpaceChain's satellite vehicles with the eventual aim of storing data on other planets. The joint effort will help launch the Earth Library.

The Pardus Linux distro offers an inviting computing experience with both old and new options. However, a dual development path narrows its user appeal. Pardus suffers from sharing its personality -- splitting its attention between an enterprise edition and a community version. While they both share the same distro name, they come from different developer teams.

Kali Linux, a penetration testing app from Offensive Security, has become available in the Microsoft Store. Windows 10 users can download and install the Kali Linux app onto the Windows Subsystem for Linux. Microsoft last summer announced that WSL, which makes it possible to run operating systems like Ubuntu, would become a fully supported part of the Windows 10 Fall Creators Update.

Microsoft has announced the first major upgrade to its Quantum Development Kit since its introduction last year. It has added several new features designed to open the platform to a wider array of developers, including support for Linux and macOS, as well as additional open source libraries. Further, the kit will be interoperable with the Python computing language.

It's common for Linux users to hop between distributions and survey the field, and I recently reached a point where I had to seriously rethink the one I was using most of the time. Between hardware compatibility issues with my old standby and some discouraging missteps with other go-to choices, I felt the time had come to reassess my pool of preferred distributions and repopulate it from scratch.

Disruptive innovations expose longstanding needs and signal that there's a solution at hand -- one that usually is less expensive than the status quo. The lower-cost aspect makes adoption inevitable and disruptive. Document management is like that. Decades ago, many enterprises found that the cost of capturing documents as electronic images vastly improved on costly file cabinet systems.

The Endless OS is a distro with its own adapted desktop environment based on Gnome 3, and with an even simpler and more streamlined user experience. Although it looks and feels a lot like an Android shell running on a PC, Endless OS is a fully functional Linux distro designed to be easy to install and use. The latest version includes automatic updates and improved application launch speeds.

SentinelOne this week announced a partnership with Microsoft to bolster threat protection for mixed platform users, making computing safer for Linux machines in a multiplatform workplace. SentinelOne will integrate its Endpoint Protection Platform with Microsoft's Windows Defender Advanced Threat Protection service to cover Mac and Linux device platforms.

Namib is an ideal Linux distro for anyone who wants to ease into the Arch approach to computing. Namib is a newcomer -- the third and current release arrived late last year. However, it makes up for its lack of age by its performance. Namib makes Arch simple. Surprisingly very user-friendly as well as compatible with older computers, Namib also is very stable.

Apple lawyers have sent a copyright violation notice to Github, following the publication of leaked iOS 9 source code on the site. Though iOS 9 is dated, it's possible that the leaked code could be used to jailbreak older devices or worse. Publication of the code violated Apple's rights under the DMCA, the attorneys wrote, demanding that the iBoot source code be removed.

Meaningful security is more than an app or an OS. It's a mindset. Linux security tools by themselves will not make you or anyone more secure. Security requires trade-offs in convenience, so the tools I'll highlight here are not recommended as "daily drivers." Only you can determine your ideal balance point. Perhaps the single greatest strength of Linux is that it is open source.

Saturday marks the 20th Anniversary of open source, sort of. Open source led to a new software development and distribution model that offered an alternative to proprietary software. No single event takes the prize for starting the technology revolution. However, Feb. 3, 1998, is one of the more significant dates. On that day, Christine Peterson, a futurist and lecturer in the field of nanotechnology, coined the "open source" term.

Canonical has announced the availability of Skype as a Snap file, the universal Linux app packaging format. Skype now can deliver its communication service to a wider range of Linux users, not just those who run Canonical's Ubuntu Linux distribution. Skype, a Microsoft product, is an application that lets users make video and voice calls, and send files, video and instant messages.

SentinelOne has released Blacksmith, a free Linux tool that can detect Meltdown vulnerability exploitation attempts. The company has been working on a similar tool to detect Spectre vulnerability attacks. Though free, Blacksmith is not open source. SentinelOne decided to expedite its development in-house to save time, said Raj Rajamani, vice president of product management.

SolydXK is a Debian-based Linux distribution that comes with a choice of the Xfce or KDE desktop. The latest edition of SolydXK, released this month, provides a state-of-the-art Linux platform. Since I first reviewed the SoldXK distro back in 2013, it has grown into a reputable Linux offering built around two popular computing options. Those two desktop options drew me to the Linux OS years ago.

Apple has unveiled new features that will become available when iOS 11.3 is released this spring. The company released the developer preview to members of the iOS Developer Program, and a public beta is expected shortly. The update will provide new ways to experience AR on the iPhone and iPad, offer new Animoji on the iPhone X, and give users a consolidated view of their health records.

Barcelona city officials have voted to shut the door on Microsoft Windows in favor of the Linux operating system and open source technology. The city hopes to save money from proprietary software license fees and to build a specialized library of open source applications targeting the needs of government workers. Its goal is to encourage specialized open source solutions throughout governmental agencies in Spain.

Many in the open source community worked feverishly this week to respond to heightened fears that software updates to fix the Spectre and Meltdown vulnerabilities would put millions of computers at risk of slowdowns or even total disability. Updated kernels were released for mitigation of Meltdown variant 3, or CVE-2017-5754, for X86-64 architecture, said Canonical VP Dean Henrichsmeyer.

Major tech companies, including Intel, Microsoft and Google, scrambled to calm the mood this week after a large number of computer users reported performance problems linked to security updates for the Spectre and Meltdown vulnerabilities. A firestorm of criticism has erupted over the response to the chip flaws, which researchers at Google's Project Zero discovered in 2016.

GeckoLinux offers both seasoned users and new distro adopters an easy way to try an openSuse-based spin that is loaded with features and an ample inventory of the leading Linux desktops. The developer released a major update of GeckoLinux earlier this week. I enjoyed testing the beta version last fall, and I was even more pleased with the added embellishments packed into this final version.

As much as I love to poke at the inner workings of my computer, I'll admit that until recently, I didn't give much thought to which version of the Linux kernel my desktop system was running. For most desktop users, this isn't all that odd. Compatibility of kernel modules is often critical for servers and production systems, but day-to-day desktop usage doesn't change much from update to update.

A renowned Linux innovator has developed a new mobile operating system, called "Project eelo," in an effort to provide a level of data privacy that traditional Android and iOS devices fail to offer. The new eelo system will allow mobile phone users to regain control over their personal information at a price they can afford, said Gael Duval, who created Mandrake Linux back in 1998.

A design flaw in all Intel chips produced in the last decade is responsible for a vulnerability that puts Linux, Windows and macOS-powered computers at risk, according to multiple press reports. The flaw reportedly is in the kernel that controls the chip performance, allowing commonly used programs to access the contents and layout of a computer's protected kernel memory areas.

SoftMaker Office could be a first-class professional-strength replacement for Microsoft Office on the Linux desktop. The Linux OS has its share of lightweight word processors and a few nearly worthy standalone spreadsheet apps, but very few high-end integrated office suites exist for Linux users. Generally, Linux office suites lack a really solid slide presentation creation tool.

Newcomer ArchMerge Linux offers a big change for the better to those switching from the Debian Linux lineage to the Arch Linux infrastructure. ArchMerge Linux is a recent spinoff of ArchLabs Linux, which is a step up from most Arch Linux offerings in terms of installation and usability. Arch Linux distros are notorious for their challenging installation and software management processes.
