Canonical Adds Multipass Cleanbuild Support to Its Snapcraft Snap Creator Tool

Filed under
Ubuntu

Snapcraft 2.42 comes less than two weeks after version 2.41, which improved the mechanism for overriding lifecycle steps, passthrough property, error reporting, and updated the dotnet, nodejs, and python plugins, to add even more enhancements to the utility that helps application developers to package their apps as Snaps.

In Snapcraft 2.42, there's a new feature called multipass cleanbuild support, which might come in handy to users of snapcraft cleanbuild with multipass installed. To try it out, you'll have to run the "$ SNAPCRAFT_BUILD_ENVIRONMENT=multipass snapcraft cleanbuild" command in the terminal emulator.

MeX Linux OS Drops Linux Mint Base, It's Now Based on Ubuntu 18.04 LTS

Filed under
OS
Ubuntu

If previous versions of the MeX Linux distribution were based on Linux Mint, starting with build 180426, the operating system is now only based on packages from the Ubuntu and Debian GNU/Linux software repositories. The latest release is derived from the Ubuntu 18.04 LTS (Bionic Beaver) operating system series.

"Mex Linux is no longer based on Linux Mint," said Arne Exton. "MeX Build 180426 is based only on Debian and Ubuntu 18.04 LTS (Long Term Support). I have replaced the original kernel with “my” special kernel 4.15.0-19-exton. All packages in MeX Linux have been upgraded to the latest version by 180426."

  • Flatpak Linux Application Sandboxing & Distribution Framework Learns New Tricks

    Flatpak, the Linux application sandboxing and distribution framework, has been updated recently to version 0.11.4, a maintenance update that introduces numerous important changes.

    With Flatpak 0.11.4, the development team updated the "flatpak build" command to allow it to always use multi-arch support, as well as to mount app extensions during the build process. In addition, the "flatpak build-init" command now supports adding of extension points earlier than build-finish by using the --extension argument, and build-finish now supports the --remove-extension argument.

    Updates were also made to the "flatpak uninstall" command, which can now pick the user or system automatically if they're not specified, the "flatpak run" command, which received several new options like --no-a11y-bus and --no-documents-portal. Also, users can now use "flatpak remove" (without quotes) as an alias for the "flatpak uninstall" command.

  • Create a Linux desktop application with Ruby

    Recently, while experimenting with GTK and its Ruby bindings, I decided to write a tutorial introducing this functionality. In this post, we will create a simple ToDo application (something like what we created with Ruby on Rails) using the gtk3 gem (a.k.a. the GTK+ Ruby bindings).

  • The pain of installing custom ROMs on Android phones

    A while back I bought a Nexus 5x. During a three-day ordeal I finally got Omnirom installed - with full disk encryption, root access and some stitched together fake Google Play code that allowed me to run Signal without actually letting Google into my computer.

    A short while later, Open Whisper Systems released a version of Signal that uses Web Sockets when Google Play services is not installed (and allows for installation via a web page without the need for the Google Play store). Dang. Should have waited.

    Now, post Meltdown/Spectre, I worked up the courage to go through this process again. In the comments of my Omnirom post, I received a few suggestions about not really needing root. Hm - why didn't I think of that? Who needs root anyway? Combining root with full disk encryption was the real pain point in my previous install, so perhaps I can make things much easier. Also, not needing any of the fake Google software would be a definite plus.

    This time around I decided to go with LineageOS since it seems to be the most mainstream of the custom ROMs. I found perfectly reasonable sounding instructions.

  • Monthly News – April 2018

    Before anything else, let’s thank all the people who contribute to this project. Many people do, in very different ways. Special thanks to our donors to our “silent friend” from Germany for the coffee!

    Many thanks also to all the developers who interacted with us on Github lately. We’ve seen a lot of new faces and very cool contributions. A slack team was recently set up to improve communication between new developers and the development team.

  • Linux Mint Continues Work On Mint 19, LMDE 3

    The Linux Mint project has published their monthly recap of activities going on for April with this popular desktop Linux distribution.

    To little surprise, much of their time has been spent on setting up their re-base against Ubuntu Bionic (Ubuntu 18.04) for Linux Mint 19 and Debian Stretch for the upcoming LMDE3 (Linux Mint Debian Edition). As part of these upcoming OS releases, they have also been buttoning up the Cinnamon 3.8 desktop environment update.

USB 3.2 Work Is On The Way For The Linux 4.18 Kernel

Filed under

Hardware

USB 3.2 was announced last summer as an incremental update to the USB standard to double the bandwidth for existing USB Type-C cables.

We haven't seen much in the way of USB 3.2 mentions in the Linux kernel yet but then again we haven't really seen USB 3.2 devices yet. USB 3.2 brings a multi-lane operation mode for hosts and devices using existing Type-C cables as well as a minor update to the USB hub specification. USB 3.2 allows for new 10 Gbit/s and 20 Gbit/s rates using two lanes, USB 3.2 Gen 1x2 and USB 3.2 Gen 2x2, respectively.

It's looking like kernel developers are now working on getting their USB 3.2 Linux support in order. We were tipped off that as of last week there are some USB 3.2 patches queued in the usb-next tree maintained by Greg Kroah-Hartman's.

Tired of Windows and macOS? Try out elementary OS

Filed under
GNU
Linux

It’s interesting to change your default OS to try out something new sometimes, but then if you already have Windows 10 on your machine, I don’t see a strong argument to install elementary OS. Some might prefer it, but I think I will go back to Windows for now and check back with other solutions in the future. Please consider this as my own humble opinion. I recommend you to try out new solutions and find your own favorites. So, can elementary OS replace the big players? It could, but I suppose it’s mainly depending on the tools you (want to) use in your workflows.

If you mostly leverage software that’s exclusively available on Windows or macOS, it doesn’t really work out to swap between the systems, but if you can manage to shift it all towards Linux, you might survive the transition without too much pain points. If you’re mostly working within Google Chrome, you can also just install Chrome for Linux on elementary OS and run your work like that. In this particular case, you’ll feel almost no change, but then, you might as well opt for Remix OS or another type of Chrome OS.

Foliate’s developer, John Factotum, is one such dev — nice work!

  • The Gecko Hacker's Guide to Taskcluster

    I spent a good chunk of this year fiddling with taskcluster configurations in order to get various bits of continuous integration stood up for WebRender. Taskcluster configuration is very flexible and powerful, but can also be daunting at first. This guide is intended to give you a mental model of how it works, and how to add new jobs and modify existing ones. I'll try and cover things in detail where I believe the detail would be helpful, but in the interest of brevity I'll skip over things that should be mostly obvious by inspection or experimentation if you actually start digging around in the configurations. I also try and walk through examples and provide links to code as much as possible.

Events: Plasma Sprint, PyCon, SciPy and All Systems Go!

  • Plasma sprint, 2019 edition; personal updates

    In June, I had a great time at a series of KDE events held in the offices of Slimbook, makers of fantastic Neon-powered laptops, at the outskirts of Valencia, Spain. Following on from a two-day KDE e.V. board of directors meeting, the main event was the 2019 edition of the Plasma development sprint. The location proved to be quite ideal for everything. Slimbook graciously provided us with two lovely adjacent meeting rooms for Plasma and the co-located KDE Usability & Productivity sprint, allowing the groups to mix and seperate as our topics demanded - a well-conceived spatial analog for the tight relationship and overlap between the two. [...] In KDE e.V. news, briefly we stole one of the sprint rooms for a convenient gathering of most of our Financial Working Group, reviewing the implementation of the annual budget plan of the organization. We also had a chance to work with the Usability goal crew (have you heard about KDE goals yet?) on a plan for the use of their remaining budget -- it's going to be exciting. As a closing note, it was fantastic to see many new faces at this year's sprint. It's hard to believe for how many attendees it was their first KDE sprint ever, as it couldn't have been more comfortable to have them on board. It's great to see our team grow.

GNOME: GSOC, GNOME Foundation, GLib

  • Gaurav Agrawal: GSOC Progress by Mid July

    July Marked the beginning of II GSOC coding month. This month our goal is to make the diff bar model as accurate and intuitive as possible. One of the biggest thing which I learnt so far is how to contribute on upstream repositories on which our project depends. In our case this was with Libgit2, we discovered a bug in Libgit2 while doing our project, and Albfan made this a perfect example to show me how to contribute on upstream, how to raise bugs and how to do discussions for getting it solved.

  • You can't say Go without Google – specifically, our little logo, Chocolate Factory insists

    Back in 2009, Google chose to name its latest programming language Go, a decision that is still giving it a migraine It could have called it "Google Go" to avoid confusion with Frank McCabe's Go! programming language. Despite criticism, it didn't do so. After almost a year of online grumbling, Google software engineer Russ Cox, in 2010, closed GitHub Issue #9, dismissing the complaints as "unfortunate." And the headaches over the thing's name still won't go away (no pun intended.) Last week, Google rebuffed a request to remove its logo from the Go website, golang.org, a change supported by some developers who feel Google takes Go developers for granted.
