How To Boot Into Linux Command Line

Filed under
Linux

There may be times where you need or want to boot up a Linux system without using a GUI, that is with no X, but rather opt for the command line. Whatever the reason, fortunately, booting straight into the Linux command-line is very simple. It requires a simple change to the boot parameter after the other kernel options. This change specifies the runlevel to boot the system into.

  • Barcelona to ditch Microsoft in favour of open source software

    THE SPANISH CITY OF BARCELONA plans to replace its Microsoft software with open source alternatives including Linux, Libre Office and Open Xchange.

    Barcelona plans to invest 70 per cent of its annual software budget in open source this year, according to El Pais, with the aim of completing the transformation by spring 2019.

    Microsoft's Outlook and Exchange Server email software is to be replaced by Open-Xchange, Microsoft Office will be ditched in favour of Libre Office, and Mozilla's Firefox will be made the default browser across systems.

  • Barcelona becomes the poster child for Linux

    The City of Barcelona is migrating its computer systems away from Windows making it the poster child for Open Source rather than Munich which is frantically trying to migrate back.

    According to the Spanish newspaper El País, the City's strategy is first to replace all user applications with open-source alternatives until the underlying Windows operating system is the only proprietary software remaining. Then the operating system will be replaced with Linux.

    Commissioner of Technology and Digital Innovation at Barcelona City Council, Francesca Bria, said the transition would be completed before the current administration's mandate ends in spring 2019.

  • Barcelona gives Microsoft the boot in move to open source

    With this move Barcelona becomes the first city to join an initiative by Free Software Foundation Europe dubbed 'Public code, public money' which calls on public bodies to invest tax revenues in free reusable systems that are open to local businesses rather than proprietary licensed software.

  • Barcelona to ditch Microsoft in favour of open source Linux software

    Catalan capital Barcelona is planning to ditch proprietary software products from Microsoft in favour of free, open source alternatives such as Open-Xchange email.

    That’s according to a report by Spain's national paper El Pais, which reports that Barcelona plans to invest 70% of its annual software budget in open source this year.

Dr. Lovesource: Or how I learned to stop worrying and love the open

OSS

I used to write code. I don't anymore. There are lots of reasons for this, including the fact that I wasn't very good at it. To clarify, I was, I think, good at writing code,1 but I wasn't very good at writing code.2 It turns out that I'm quite good at a variety of other things, so my career3 moved in a different direction—or, in fact, a variety of different directions. After a number of roles ranging from "Electronic Information Controller" to "Product and Programme4 Manager" through software engineering and pre-sales, I finally settled into something called "architecture." Which means that I mainly draw boxes and lines on whiteboards and expect people who are very good at writing code to make the boxes "real."

Every Linux desktop environment comes with at least a simple desktop calculator, but most of those simple calculators are just that: a simple tool for simple calculations.

Fortunately, there are exceptions; programs that go far beyond square roots and a couple of trigonometric functions, yet are still easy to use. Here are two powerful calculator tools for Linux, plus a couple of bonus options.

    A new emulator that aims to open up the doors to Nintendo Switch-exclusive games has just been announced for computers. Named Yuzu, the emulator was created by the same team that designed Citra, a similar 3DS emulator. Yuzu's official website calls it an "experimental" open-source emulator, and has builds ready and maintained for PC, Mac, and Linux. The project is "in its infancy" for now, but has some pretty big goals on the horizon.

  • I pushed an implementation of myself to GitHub

    Roughly 4 years ago, I mentioned that there appears to be an esotieric programming language which shares my full name.

    I know, it is really late, but two days ago, I discovered Racket. As a Lisp person, I immediately felt at home. And realizing how the language dispatch mechanism works, I couldn't resist and write a Racket implementation of MarioLANG. A nice play on words and a good toy project to get my feet wet.

    The ASUS AM1I-A as implied by the name is an AM1 socket motherboard for those Athlon/Sempron processors... Not nearly as exciting as if a Ryzen motherboard would be supported by Coreboot, but this motherboard isn't too old compared to some other Coreboot ports and can still be found from a few online shops albeit refurbished. The ASUS AM1I-A is a mini-ITX board with USB 3.0, DVI/HDMI/VGA outputs, and all the other usual candidates for an AM1 class motherboard.

  • Open source model, drugs for the masses

    Nearly one person dies of tubercolosis every two minutes in India, said Professor Jaykumar Menon, the award-winning international human rights lawyer and social entrepreneur. Professor Jaykumar began the Open Source Pharma Foundation, which looks at generating breakthroughs in affordable public healthcare; the initiative has drawn over $110 million in funding the likes of Tata Trusts, Gates Foundation, Rockefeller Foundation and the Soros Foundations. Speaking at the National Institute of Advanced Studies in Bengaluru, Menon said, "We are working on complex issues that affect Indian and global society. Our first target, therefore, is Mycobacterium tubercolosis, which inhabits approximately a quarter of the human population in India."

  • #DLNchat: Open Educational Resources (OER) in Higher Ed

    Can open educational resources, or OER, truly create more equity and access? That was the question at the heart of our #DLNchat on January 9, which centered around OER in Higher Education. Our special guest, Lisa Petrides, creator of OER Commons, kicked things off by defining the topic at hand: “OER are teaching & learning materials freely available for anyone to use. These materials typically reside in the public domain, or have an alternative copyright license, i.e. Creative Commons or GNU, that specify how the resource may be reused, adapted, and shared. To me OER is also about the democratization of access to education, and the pursuit and sharing of knowledge. And the ecosystem of open knowledge sharing is fundamental to teaching, to learning, and to equity."

deepin 15.5 - A different desktop

Filed under
GNU
Linux
Reviews

deepin is a Debian-based Linux distribution which features the custom Deepin Desktop Environment along with several in-house desktop applications. The deepin project develops its own file manager, media players, software centre and settings panel, along with other desktop applications. Clearly, the deepin team is very busy working on a desktop solution, one which is easy to navigate.

deepin is available as a 3.2GB download for 64-bit x86 computers. Booting from the project's media gives us the option of starting the installation process, booting the operating system in failsafe mode or checking the media's integrity. In both of my test environments, deepin would boot and launch the installer (the first option), but was unable to boot in failsafe mode, whether run in UEFI or Legacy BIOS mode.

Taking the install option brings up a graphical environment where we are asked to select our preferred language from a list. In the upper-right corner of the screen there is an "X" which, when clicked, lets us abort the installation. Quitting the installer immediately powers off the computer. Once we have selected our language we are asked to create a username and password for ourselves. We can then select our time zone from a map of the world.

Partitioning comes next and here I encountered several options. We are asked whether we want Simple or Advanced partitioning. The Simple option takes over the entire hard drive, creating an ext4 file system. A 4GB swap file is set up on the root partition for us. This is the easy way forward, but it wipes out any other installed systems or partitions.

The Advanced option lets us select where to install the system's boot loader and presents us with a list of available partitions and free space. At first I wasn't able to find any way to add new partitions, but eventually found the button for adding and editing partitions is a grey icon on a grey background, making it difficult to spot. Once the button was found, setting up new partitions was fairly straight forward. The deepin installer will not proceed if the root partition is 16GB or smaller in size when we take the Advanced partitioning option. However, I found I could create a root partition smaller than 16GB if I used the Simple partitioning option. Once our partitions are assigned mount points, the installer copies its files to the computer and reboots the system.

Linux 4.15 RC8 and Linux Kernel Mailing List Downtime

Filed under
Linux
  • Linux 4.15-rc8

    Ok, another week has gone by, and here's the promised rc8.

    I'm still hoping that this will be the last rc, despite all the
    Meltdown and Spectre hoopla. But we will just have to see, it
    obviously requires this upcoming week to not come with any huge
    surprises.

    The patches aren't huge, but architecture updates do end up being a
    largish part. That's partly due to the x86 "retpoline" support (well,
    the basic stuff that is uncontested), but also because the powerpc
    people decided they wanted to play too, so there's some low-level
    kernel entry changes there too. Aren't we lucky?

    Oh, and there's a small RISC-V update too.

    But outside of that, we've got driver updates (gpu, networking, usb,
    sound, NVMe), some core networking, and some tooling updates (mostly a
    few new x86 selftests). And some random misc fixlets (documentation,
    apparmor, crypto).

    Go forth and test. It all looks pretty solid to me,

  • Kernel prepatch 4.15-rc8

    The 4.15-rc8 kernel prepatch is out for testing. Among other things, it includes the "retpoline" mechanism intended to mitigate variant 2 of the Spectre vulnerability. Testing of this change will be hard, though, since it requires a version of GCC that almost nobody has — watch LWN for a full article in the near future.

  • Introducing the CAPS0ff Project

    It's no secret that I love classic video games. Fortunately, thanks to emulation, many of the classic arcade games still can be enjoyed and forever will be available via digital copies of the ROM chips. Sadly, some older systems have protection, making them impossible to dump into ROMs properly. If the chips can't be dumped, how will you ever get a digital copy of the ROM data? Well, the folks over at the CAPS0ff blog actually are disassembling the original chips and painstakingly transcribing the contents one bit at a time. They're literally looking at the chips and determining the 1s and 0s burned onto them.

  • Some Of What's Coming For Wayland's Weston 4.0 Compositor

    Earlier this week ongoing Wayland/Weston release manager Bryce Harrington at Samsung laid out plans for Wayland 1.15 and Weston 4.0. There's been some push-back on the proposed dates to try to allow some more work to land in these upcoming six month releases to Wayland/Weston, but long story short, these next releases will be here in the near future.

    With Wayland itself quite mature, there isn't much that's exciting for end-users about Wayland 1.15. In fact, not many changes at all unless there's a last-minute rush of new work to land. As is the case these days, most of the interesting work is happening within the Weston compositor space as developers flesh out new functionality and prototype features that will hopefully be picked up by the other Wayland compositors that are becoming widely used on the Linux desktop.

    The graphics numbers were omitted from yesterday's article as I had to make some tweaks to its parser and post-processor due to the wide assortment of graphics driver/hardware combinations, joining the ATI and AMD data, etc compared to the statistics collection on more basic/uniform hardware components. The sample set used was a maximum of 100,000 systems per year with the data being collected through the Phoronix Test Suite and OpenBenchmarking.org.

Benchmarking Ubuntu's Low-Latency Kernel & Liquorix Post-Meltdown

Filed under
Graphics/Benchmarks
Security
Ubuntu

The Ubuntu low-latency kernel is designed for, well, low-latency workloads like audio processing/recording. The lowlatency kernel compared to the generic Linux x86_64 kernel enables IRQ_FORCED_THREADING_DEFAULT, disables TREE_RCU in favor of PREEMPT_RCU, disables OPTPROBES, enables UNINLINE_SPIN_UNLOCK while disables the INLINE_*_UNLOCK tunables, enables PREEMPT support, changes to 1000Hz tick from 250Hz, and enables LATENCYTOP support.

The Liquorix kernel continues to be a bit more unique and among its alterations compared to a generic kernel is Zen interactive tuning, making use of the MuQSS process scheduler, hard kernel preemption, BFQ I/O scheduler by default, network optimizations, and more as outlined at Liquorix.net. Liquorix also defaults to CPUFreq on Intel CPUs and uses the ondemand governor rather than the other tested kernels defaulting to P_State powersave.

For these tests were benchmarks of 4.13.0-25-generic (the current default Ubuntu 17.10 kernel with KPTI patched), 4.14.13-041413-generic as the latest upstream stable kernel from the Ubuntu Mainline Kernel PPA, 4.14.13-041413-lowlatency as the equivalent low-latency Ubuntu kernel, and then 4.14.0-13.1-liquorix as the latest Liquorix kernel via its Launchpad PPA. All of these kernels had KPTI protection present and enabled, none of them currently have the (currently out-of-tree) Retpoline support.

My Linux story: Coding not required

For more than 15 years, I have earned a living working exclusively with open source products. How did I get here? In many ways, my journey started before Linux existed. In college, I had friends who were admins in the engineering computer lab. Although I did not do too well in my CS programming classes, as a hobby and to spend time with my friends I learned about newgroups, ftp sites, and Unix systems. As a data aide student intern, I realized I made a good translator between the astronomers and the C programmer computer support staff. I could read just enough code to identify the problem, but not enough to actually fix it. Read more
