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.

  • 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.

To make this process far easier than the traditional one of designing a robot by hand, writing some code and doing thorough testing, a team of researchers from UCLA and Texas A&M has created the Mobiot toolkit, which aims to combine each of these steps into a very straightforward application that takes care of the heavy lifting automatically.

  • DrKonqi ❤️ coredumpd

    Since Plasma 5.24 DrKonqi, Plasma’s infamous crash reporter, has gained support to route crashes through coredumpd and it is amazing – albeit a bit unused. That is why I’m telling you about it now because it’s matured a bit and is even more amazing – albeit still unused, I hope that will change. To explain what any of this does I have to explain some basics first, so we are on the same page… Most applications made by KDE will generally rely on KCrash, a KDE framework that implements crash handling, to, well, handle crashes. The way this works depends a bit on the operating system but one way or another when an application encounters a fault it first stops to think for a moment, about the meaning of life and whatever else, we call that “catching the crash”, during that time frame we can apply further diagnostics to help later figure out what went wrong. On POSIX systems specifically, we generate a backtrace and send that off to our bugzilla for handling by a developer – that is in essence the job of DrKonqi.

  • What's In That String?

    One of the steps of debugging Perl can be to find out what is actually in a string. There are a number of more-or-less informative ways to do this, and I thought I would compare them. For this I used two short strings. The first was just the concatenation of the characters whose ordinals are 24 through 39; that is, 16 ASCII characters straddling the divide between control characters and printable characters. The second was a small variation on the first, made by removing the last character and appending "\N{U+100}" (a.k.a. "\N{LATIN CAPITAL A WITH MACRON}") to force the string's internal representation to be upgraded. The results given below include the version of the module used, the actual code snippet that generated the output, the output itself, and any comments I thought relevant. All subroutines used to dump strings are exportable except for those called as methods. The sample code makes fully-qualified calls because of duplication of subroutine names between different modules.

  • Our build and release infrastructure, and upcoming updates | F-Droid - Free and Open Source Android App Repository

    Behind the scenes of F-Droid is a giant pile of automation to manage the process of building thousands of apps from source. This means checking out thousands of source repos, checking them all for updates, building and new releases, and securely signing them en masse. All builds are run in a fresh virtual machine guest instance known as the buildserver. All Gradle binaries and Android SDK packages are verified against our public logs of observed SHA-256 checksums. The transparency log processes also verify against upstream’s public checksums. Our setup runs on Debian almost exclusively. Debian is a leader in free software, rock solid servers, and reproducible builds. That makes it a natural home for F-Droid. We also work to ensure we maintain the packages we use, and build our processes on top of Debian packages. That means we share the maintenance with anything that uses Debian. It may seem like more work to give back, but our experience is that it pays off in the long run. The F-Droid community is able to maintain many things with a small team. Another example of this is this website itself: it is built using Jekyll packages that are all in Debian.

  • Stable Channel Update for Desktop
  • Google has been DDoSing SourceHut for over a year

    Just now, I took a look at the HTTP logs on git.sr.ht. Of the past 100,000 HTTP requests received by git.sr.ht (representing about 2½ hours of logs), 4,774 have been requested by GoModuleProxy — 5% of all traffic. And their requests are not cheap: every one is a complete git clone. They come in bursts, so every few minutes we get a big spike from Go, along with a constant murmur of Go traffic. This has been ongoing since around the release of Go 1.16, which came with some changes to how Go uses modules. Since this release, following a gradual ramp-up in traffic as the release was rolled out to users, git.sr.ht has had a constant floor of I/O and network load for which the majority can be attributed to Go. I started to suspect that something strange was going on when our I/O alarms started going off in February 2021 (we eventually had to tune these alarms up above the floor of I/O noise generated by Go), correlated with lots of activity from a Go user agent. I was able to narrow it down with some effort, but to the credit of the Go team they did change their User-Agent to make more apparent what was going on. Ultimately, this proved to be the end of the Go team’s helpfulness in this matter.
