Behind the scenes with Pop!_OS Linux

Ubuntu

In October, Linux PC maker System76 released its homegrown version of Linux, Pop!_OS, giving users the choice between its legacy Ubuntu operating system or the new Pop!_OS flavor of Linux. Recently Opensource.com gave away a System76 laptop with Pop!_OS installed, which made me curious about the company and this new version of Linux, so I spoke with Cassidy James Blaede, Pop!_OS's user experience (UX) designer.

Blaede joined System76 in 2014, fresh out of college at the University of Northern Iowa and marriage to his wife, Katie. While in college, he co-founded the elementary OS project and interned at UX consultancy Visual Logic, both of which influenced his work for System76. He started at System76 as a front-end developer and was later promoted to UX architect.

Microsoft

Despite what you may have been led to believe, there are in fact a number of solid Linux alternatives for Microsoft Office available. In fact, there are even options available with varied levels of docx support, if that is something relevant to your business.

This article will explore my recommended Microsoft Office alternatives for Linux. Some of them you've likely heard of, others may be cloud/server based options that you might not have thought much about until now.

Hardware

Axiomtek’s compact “IFB125” DIN-rail IoT gateway runs Yocto Linux on an i.MX6 UL SoC with dual LANs, mini-PCIe expansion, extended temperature and vibration resistance, COM and USB ports, and a DB9 port that supports both SPI and I2C.

Axiomtek has released a minor variation on its IFB122 IoT gateway. Like the IDB122, the new IFB125 runs Yocto Project code with Linux 3.14.52 on NXP’s 528MHz Cortex-A7 based i.MX6 UltraLight (UL) SoC. The headless gateway is designed for remote control and remote monitoring management applications such as unmanned control room, industrial automation, automatic parking lot, and traffic cabinets.

  • Analyzing the Linux boot process

    The oldest joke in open source software is the statement that "the code is self-documenting." Experience shows that reading the source is akin to listening to the weather forecast: sensible people still go outside and check the sky. What follows are some tips on how to inspect and observe Linux systems at boot by leveraging knowledge of familiar debugging tools. Analyzing the boot processes of systems that are functioning well prepares users and developers to deal with the inevitable failures.

  • BPF Getting Error Injection & More In Linux 4.16

    While BPF has been under the spotlight recently in light of Spectre, with the upcoming Linux 4.16 cycle this in-kernel virtual machine and originally packet filter will be picking up new features.

  • Jailhouse Guest Support Queued For Linux 4.16

    Yet more functionality to find with the upcoming Linux 4.16 kernel is the first bits of Jailhouse hypervisor functionality being mainlined.

    Since at least 2013 Siemens has been developing the Jailhouse hypervisor for Linux systems. This partitioning hypervisor aims to be lighter than KVM and Siemens has been designing it for "highly demanding real-time, safety or security" workloads.

  • Retpoline patch coming to Linux 4.9 and Linux 4.14

    Several Linux kernel versions, including 4.9, 4.14, and the upcoming 4.15, will have Retpoline support built in to mitigate against the Spectre vulnerability. Greg Kroah-Hartman, one of the head honchos overlooking kernel development, accepted the patch into the 4.9 and 4.14 kernels meaning Linux users everywhere should be secure from Spectre without any performance hits.

    The exact kernel versions to look out for are 4.9.77 and 4.14.14. Unfortunately, for those of us still on Linux 4.4 and 3.18, which are still supported, there is no sign of the Retpoline patch just yet despite getting receiving other updates. Hopefully it’ll be released in a subsequent update after they’ve had time to monitor for any problems in 4.9 and 4.14.

  • Retpoline Support Backport Lands In GCC 7

    The backporting of -mindirect-branch, -mindirect-return and -mindirect-branch-register, a.k.a. the GCC "Retpoline" patches, have been back-ported and merged into the GCC 7 branch.

    Given the severity of the Spectre vulnerability, these features for Retpoline support are being back-ported to GCC branches normally only reserved for bug/regression/documentation fixes.

  • Linux kernel mailing list back online; Meltdown and Spectre vulnerabilities; Mobile OS eelo; Barcelona now using Linux

    The popular Linux Kernel Mailing List website is back online after going down and staying down for several days due to a power outage to the home server where it was hosted. Upon reboot, a password (for dm-crypt) was required to mount the root device; however, that in itself was not the problem. The problem was the fact that the PC’s owner, Jasper, was on vacation when all of this occurred. Anyway, the site is now back up and continuing to operate as it always has.

    Speaking of the kernel mailing lists, Johannes Weiner issued a call for proposals for agenda topics to the upcoming annual 2018 Linux Storage, Filesystem and Memory Management (LSF/MM) Summit. The deadline is January 31, 2018, and the summit will be held between April 23-25 At Deer Valley Lodges in Park City, Utah. For more information, visit the Linux Foundation Events page.

Barcelona is moving to Linux; why not Dhaka?

Linux

The Spanish city of Barcelona just announced a few days ago (https://www.itwire.com/open-source/81377-barcelona-plans-move-to-open-source-software.html) that it has successfully completed a pilot project of moving 1,000 desktops of municipality employees from Microsoft Windows and MS Office to free/open-source alternatives, Ubuntu Linux (www.ubuntu.com/desktop) and LibreOffice (www.libreoffice.org).

The question is why countries like Bangladesh, which are much less wealthy than Spain, are not making similar moves to replace expensive Microsoft software with free/open-source alternatives.

The simple fact is that there is almost no awareness of the real cost of Microsoft software in Bangladesh, as software piracy is so commonplace. Every market has shops stocking pirated MS Windows/MS Office DVDs; so the public can be forgiven for thinking that these are practically free of cost.

Our Favourite Apps for Ubuntu

We enjoy using Ubuntu mainly for gaming, writing, listening to music and browsing the web. (Lots and lots of browsing the web.) There are other apps that we would love to have on Ubuntu like Affinity Photo, a stunning image editor that’s on par with Adobe’s Photoshop that’s available on Windows and Mac as well as Bear, a beautifully designed note taking app that we do most of our writing on that’s only available for macOS. However, the Ubuntu platform has moved forward in leaps and bounds in recent years when it comes to the official availability of popular apps and we are confident that this trend will continue.
