This is the New Ubuntu 18.04 Default Wallpaper

Filed under

You’re gawping at the brand new Ubuntu 18.04 default wallpaper.

Yes, seriously!

The new background image will make its appearance of tens of millions of desktops with the Ubuntu 18.04 release on April 26, 2018.

Like the Ubuntu 17.10 ‘Artful Aardvark’ background new wallpaper incorprates the release mascot (which for this release is a ‘Bionic Beaver’) and is drawn using a geometric-come-origami style.

Node.js Is Now Available as a Snap on Ubuntu, Other GNU/Linux Distributions

Filed under

Now that Linux is the preferred development platform for developers visiting Stack Overflow, the need for running the latest versions of your favorite programming languages, frameworks and development environments has become more and more important, and Canonical's Snappy technologies are the answer.

NodeSource, the organization behind Node.js, announced today they made a Snap package to allow Linux developers to more easily install the popular JavaScript runtime environment on their operating systems. Snap is a containerized, universal binary package format developed by Canonical for Ubuntu Linux.

Modular PLC platform runs Linux on Allwinner H5

Filed under

UniPi’s “Axon” line of 13 DIN-rail PLC systems for smart home and building automation run Linux on an Allwinner H5, and offer GbE, WiFi, BT, and varying configurations of DIDO, analog I/O, relays, and serial I/O.

UniPi launched its flagship, Linux-based UniPi building automation add-on board for the Raspberry Pi Model B on Indiegogo back in 2014, and followed up with a more advanced Neuron PLC (Programmable Logic Controller) that integrated a Raspberry Pi 3. This week, UniPi left the Pi behind to launch a UniPi Axon line of 13 PLC computers that run Linux on a quad-core, Cortex-A53 Allwinner H5 SoC.

  • Locking down Data with Open Source Code

    The single most noteworthy quality of Linux is that it is one of the few open source working frameworks, and among the most broadly created. Confining open source programming as secure justifiably befuddles individuals, however, a closer look discloses why that is valid. At the point when source code is distributed on the web, it could enable an aggressor to find shortcomings. In any case, by and by it enables numerous more eyewitnesses to distinguish and uncover bugs to the engineers for fixing. Since Linux is an entirely open source OS, for all intents and purposes each scrap of code running on your equipment is subjected to this crowdsourced examination.

  • PostgreSQL Begins Landing LLVM JIT Support For Faster Performance

    The widely-used PostgreSQL database software may soon become much faster thanks to a work-in-progress LLVM JIT back-end that has begun to land.

    A long-running project has been JIT-compiling SQL queries in PostgreSQL by making use of LLVM's just-in-time compilation support, rather than passing SQL queries through Postgres' interpreter. With the LLVM JIT'ed queries, more efficient code is generated by being able to make more use of run-time information and can especially help in increasing the performance of complex SQL queries.

  • Management alone can't drive open culture change

    It would seem that targeted learning around how a non-hierarchical governance model practically works in a global organisation is required. This, in and of itself, is a learning expedition that needs to be highly personal. We have to be retrained to fail forward and without fear. We have to learn to criticize constructively, even our bosses. We also have to rethink things like typical management activities, job security and career pathways. Above all, we have to feel safe inside our organizations and that requires trust.

Raspberry Pi 3 Model B+ Benchmarks

Filed under

Last week on Pi Day marked the release of the Raspberry Pi 3 Model B+ with a slightly higher clocked Cortex-A53 processors, dual-band 802.11ac WiFi, faster Ethernet, and other minor enhancements over its predecessor. I've been spending the past few days putting the Raspberry Pi 3 Model B+ through its paces the past few days with an array of benchmarks while comparing the performance to other ARM SBCs as well as a few lower-end Intel x86 systems too. Here is all you need to know about the Raspberry Pi 3 B+ performance.

Raspberry Pi 3B+ Speeds Up Three Ways

Filed under

Earlier this week, the Raspberry Pi 3 Model B+ SBC touched down with the refreshing lack of hype and hoopla typical of Raspberry Pi product introductions. The modest launch may also be a tacit admission that this upgrade to the insanely popular Raspberry Pi 3 Model B checks off only one major wish-list item: the upgrade from 10/100 to 10/100/1000Mbps Ethernet. There’s still only 1GB of RAM, and there’s still no eMMC storage, let alone SATA, mini-PCIe, or M.2 expansion.

  • Big Memory Leak Bug Found In GNOME Shell; Might Remain Unpatched In Ubuntu 18.04

    For now, the users who couldn’t benefit from the patch can restart Gnome Shell after a couple of hours to free up memory. To do this, press Alt + F2. Then type r and press Enter.

  • Continues Integration in Librsvg, Part 1

    Rust makes it trivial to write any kind of tests for your project. But what good are they if you do not run them? In this blog series I am gonna explore the capabilities of Gitlab-CI and document how it is used in Librsvg.

  • Continues Integration in Librsvg, Part 2
  • Continues Integration in Librsvg, Part 3

    Generally 5min/job does not seem like a terribly long time to wait, but it can add up really quickly when you add couple of jobs to the pipeline. First let’s take a look where most of the time is spent. First of jobs currently are spawned in a clean environment, which means each time we want to build the Rust part of librsvg, we download the whole cargo registry and all of the cargo dependencies each time. That’s our first low hanging fruit! Apart from that another side-effect of the clean environment is that we build librsvg from scratch each time, meaning we don’t make use of the incremental compilation that modern compilers offer. So let’s get started.

  • [GNOME] Builder Nightly

    One of the great aspects of the Flatpak model, apart from separating apps from the OS, is that you can have multiple versions of the same app installed concurrently. You can rely on the stable release while trying things out in the development or nightly built version. This creates a need to easily identify the two versions apart when launching it with the shell.

  • SVG Rendering and GSVGtk

    For SVG rendering, we have few options: librsvg, as the most popular one,,and Lasem, maybe others. Both take an SVG file, parse it and render it over specified Cairo.Context.

  • GTask and Threaded Workers

    GTask is super handy, but it’s important you’re very careful with it when threading is involved.

  • gksu is dead. Long live PolicyKit

    Today, gksu was removed from Debian unstable. It was already removed 2 months ago from Debian Testing (which will eventually be released as Debian 10 “Buster”).

  • Google Skaffold Automates Kubernetes Orchestration

    Google is throwing an automation tool to developers looking to use Kubernetes to orchestrate enterprise applications. That assistance is coming from a command line tool dubbed Skaffold that can help continuous development for Kubernetes applications.

    Vic Iglesias, a solutions architect at Google, noted in a blog post that Skaffold allows developers to more closely mirror production methods within an enterprise. It does this by allowing developers to work on application source code in their local environment. That code can then be updated and ready for validation and testing in the developer’s local or remote Kubernetes clusters.

    Lector is a customizable, open-source Qt-based eBook that you probably haven’t heard about yet because it saw its first official release approximately 11 days ago.

    It is not an eBook manager like the famous Calibre, but it has one of the best User Interfaces and data management methods among its peers; and you can use it to read all the popular eBook formats including PDFs, Amazon Kindle books, and comics.

    For starters, it features a library viewer typical of an eBook reader, except that it is eye candy. You can customize its font type and size; page color, zoom controls, and letter spacing. You can also right-click on books to edit their metadata i.e. author, title, genre, and publication year.

  • Yoda – The Command line Personal Assistant For Your Linux System

    A while ago, we wrote about a command line virtual assistant named “Betty”. Today, I stumbled upon a similar utility called “Yoda”. Yoda is a command line personal assistant who can help you to do some trivial tasks in Linux. It is a free, open source application written in Python. In this guide, we will see how to install and use Yoda in GNU/Linux.

  • Suplemon – A Powerful Console Text Editor with Multi Cursor Support
  • Cockpit 164

    Cockpit is the modern Linux admin interface. We release regularly. Here are the release notes from version 164.

  • Release 2.2 of QSoas

    The new release of QSoas is finally ready ! It brings in a lot of new features and improvements, notably greatly improved memory use for massive multifits, a fit for linear (in)activation processes (the one we used in Fourmond et al, Nature Chemistry 2014), a new way to transform "numbers" like peak position or stats into new datasets and even SVG output ! Following popular demand, it also finally brings back the peak area output in the find-peaks command (and the other, related commands) ! You can browse the full list of changes there.

  • Progress in monitoring

    Let's start with the netstats (hard)work @antares has done (still under review for merging into libgtop master, #1 merge request on libgtop gitlab): she did investigate a lot to find the best way to get per-process network statistics into libgtop, something Usage and System Monitor both should benefit from. This is implemented currently as a root daemon using libpcap for capturing packets and summing their sizes, exposing a dbus-interface, congratulate her for the great job and tremendous patience she has shown enduring all my reviews and nitpicking comments.

Which Linux Distribution to Use After Ubuntu?

Filed under

Ubuntu is one of the best Linux distributions for beginners. It’s an excellent platform for people new to Linux. It is easy to install, has tons of free resources available along with a massive list of applications available for it.

I am not saying Ubuntu is strictly for new Linux users. I have been using Ubuntu as my primary operating system for more than eight years and I just love it.

    Yes, I need to eat and pay my bills. And until eelo becomes a success, with a working business model, the only way for me to finance my living doing some consulting. I’ve reduced this activity at the max but this currently takes me one day per week, or a little more.

    eelo is gaining some momentum, it’s super-promising. Its potential is HUGE. And it’s the most exciting professionnal project I’ve started in my life.

  • A new strategic investor joins the Sailfish family

    Sailfish OS has come a long way, starting with the MeeGo times, then carried by Jolla ever since 2011. The journey has had its ups and downs, as these kind of things typically have, but we never gave up. I recommend to check out e.g. this recent article about the journey. The most important thing that has kept us going together with our community and partners all the time is simply that we have the ability to create and offer together an alternative mobile operating system for the world.

    Next chapter in this story is about to begin as we’re getting Rostelecom, a publicly listed company and the leading telecommunications company in Russia, to officially join our wide international group of Sailfish partners.

The Magnificent Seven unique Linux projects

Filed under

While the technology landscape feels big, complex and colorful, the actual variation in creativity and uniqueness isn’t that huge. Often, ideas build upon other ideas, with small changes and incremental improvements. This is also true of our favorite domain, Linux, with its towering pyramid of distros and forks and still more forks, a whole cutlery division. Lots of stuff but not necessarily variety.

In fact, I even believe there’s a decrease in uniqueness over the years, caused by over-saturation of ideas, the demise (or at least, the decline) of several major projects, and with them, the hope and enthusiasm, and of course, the weariness of the human intellect involved. Having inadequate resources, with teams and projects stretched thin, sure does not help. But that’s the negative side. The good thing is, alongside mediocrity, there have been some really amazing things out there, and I want to give them special attention in this article.

  • Linux Mint ditches AMD for Intel with new Mintbox Mini 2
    While replacing Windows 10 with a Linux-based operating system is a fairly easy exercise, it shouldn’t be necessary. Look, if you want a computer running Linux, you should be able to buy that. Thankfully you can, as companies like System76 and Dell sell laptops and desktops with Ubuntu or Ubuntu-based operating systems. Another option? Buy a Mintbox! This is a diminutive desktop running Linux Mint — an Ubuntu-based OS. Today, the newest such variant — The Mintbox Mini 2 — makes an appearance. While the new model has several new aspects, the most significant is that the Linux Mint Team has switched from AMD to Intel (the original Mini used an A4-Micro 6400T).
  • Porting L4Re and Fiasco.OC to the Ben NanoNote (Part 3)
    So, we find ourselves in a situation where the compiler is doing the right thing for the code it is generating, but it also notices when the programmer has chosen to do what is now the wrong thing. We must therefore track down these instructions and offer a supported alternative. Previously, we introduced a special configuration setting that might be used to indicate to the compiler when to choose these alternative sequences of instructions: CPU_MIPS32_R1. This gets expanded to CONFIG_CPU_MIPS32_R1 by the build system and it is this identifier that gets used in the program code.

Both organizations have something to offer the other through the collaboration. The Linux Foundation’s OPNFV project integrates OCP as well as other open source software projects into relevant network functions virtualization (NFV) reference architectures. At the same time, OCP offers an open source option for the hardware layer.

What is interesting is that there has been a steady take-up of developers using this annotation:
