Ubuntu: LXD, New Stuff and Snaps

Filed under
Ubuntu
  • Development in LXD

    Most of my development is done in LXD containers. I love this for a few reasons. It takes all of my development dependencies and makes it so that they're not installed on my host system, reducing the attack surface there. It means that I can do development on any Linux that I want (or several). But it also means that I can migrate my development environment from my laptop to my desktop depending on whether I need more CPU or whether I want it to be closer to where I'm working (usually when travelling).

    When I'm traveling I use my Pagekite SSH setup on a Raspberry Pi as the SSH gateway. So when I'm at home I want to connect to the desktop directly, but when away connect through the gateway.

  • Snap Store Is Available for Ubuntu!, How to Install It?

    Snap is a software used to install software packages that can run on various Linux distributions. This time Snap Store can be installed and used like using the Software Center (on Ubuntu), or GNOME Software. This application was created specifically to make it easier for users when installing software packages on Snap.

    Actually, the Ubuntu Software Center and GNOME software can add the url of a software package and install it. But both of these applications will mix search results that are snap, flatpak and others.

  • An OpenJPEG Surprise

    My previous blog post seems to have resolved most concerns about my requests for Ubuntu stable release updates, but I again received rather a lot of criticism for the choice to make WebKit depend on OpenJPEG, even though my previous post explained clearly why there are are not any good alternatives.

    I was surprised to receive a pointer to ffmpeg, which has its own JPEG 2000 decoder that I did not know about. However, we can immediately dismiss this option due to legal problems with depending on ffmpeg. I also received a pointer to a resurrected libjasper, which is interesting, but since libjasper was removed from Ubuntu, its status is not currently better than OpenJPEG.

    But there is some good news! I have looked through Ubuntu’s security review of the OpenJPEG code and found some surprising results. Half the reported issues affect the library’s companion tools, not the library itself. And the other half of the issues affect the libmj2 library, a component of OpenJPEG that is not built by Ubuntu and not used by WebKit. So while these are real security issues that raise concerns about the quality of the OpenJPEG codebase, none of them actually affect OpenJPEG as used by WebKit. Yay!

  • Call for testing: chromium-browser deb to snap transition

    The chromium browser has been available as a deb package for all supported Ubuntu releases and as a snap since version 60, and the time has come to start transitioning away from the debs.

  • Canonical Announces Embedded Computer Manifold 2 for Drone Developers, Request For Help Testing Snap Package, PHP v7.4.0 Available, PyCharm 2019.2 EAP3 Released, Talks To Port Over Microsoft's Chromium-Based Edge browser To Linux

    Yesterday, Canonical, the company behind Ubuntu announced the availability of Manifold 2, a high-performance embedded computer offered by leading enterprise drone manufacturer, DJI. This availability will allow developers access to containerized software packages (e.g. Snaps), allowing for infinite evolution and functionality changes.

    It looks as if Ubuntu is transitioning the Chromium Debian package to a Snap one. The community behind this effort is asking for assistance in testing the Snap package.

Tizonia – powerful open source cloud music player for the Linux terminal

The Linux platform has matured into an excellent way of listening to streaming music services. There are clients available for most of the popular music streaming services. But what if you want a single app that covers the very popular ones without straying away from the Linux terminal. Step forward Tizonia. Tizonia offers access to some excellent streaming music services — all from the command line. The software supports popular services such as YouTube, Spotify, Google Play Music, SoundCloud, Chromecast, and more. Tizonia is innovative software. It doesn’t use FFmpeg, libav, gstreamer or libvlc for playback. Instead, the software’s multimedia framework is based on OpenMAX IL 1.2. OpenMAX (Open Media Acceleration) is a non-proprietary and royalty-free cross-platform set of C-language programming interfaces. It provides abstractions for routines that are especially useful for processing of audio, video, and still images. Tizonia is C/C++ software which integrates online services with Python connectors/proxies. This means it should be fairly easy to integrate new services, assuming a Python-based API is accessible.

What Is AppImage in Linux?

On a Linux distro, you should always install new software with the aid of your package manager when possible. It keeps things clean, and all files are tracked by the manager and can be easily removed later. This also helps avoid potential trouble when you later upgrade your distribution. But since your distribution might not have the software you need, or some might be too old, you sometimes have to resort to alternatives. Out of all these alternatives, though, only choose to download third party “.deb” or “.rpm” files as a last resort. What Is AppImage? On Windows, you can download a ZIP archive, extract the contents to a directory, and run the application within, without having to install it. This is called a portable app because you can copy it to a USB stick and then run it on any computer that uses the Windows operating system. An AppImage, though technically constructed in a different way, works the same from the user’s perspective. You download one file and run the program on your Linux operating system without having to install anything. Furthermore, you can also copy this on a USB stick, and it will run on Debian, Ubuntu, Arch Linux, openSUSE, Fedora, or any other Linux distribution. Read more

D9VK 0.13f

  • D9VK for translating D3D9 to Vulkan for Wine has another new version out, 0.13f - "Hypnofrog"

    Developer Joshua Ashton is certainly keeping busy, with another brand new release of D9VK now available. As a reminder: D9VK is based on DXVK. While DXVK focuses on translating D3D11 and D3D10 into Vulkan for use in Wine, D9VK focuses on D3D9. Eventually, they should hopefully merge into one awesome project. Version 0.13f - "Hypnofrog" is coming in less than a week after the last release, yet still manages to sound interesting given that's not a lot of time. There's some "New General API Stuff", "New Fixed Function Support", "New Shader Support" and bug fixes for "D3D9" and "DXSO (Shader Fixes)". Most of the changelog is highly technical language for those of you who understand graphics APIs. The main takeaway, as always, is that each new release should bring more compatibility with Windows games in Wine that use DirectX 9. Since D9VK uses Vulkan, it should perform better than vanilla Wine.

  • D9VK 0.13f Brings Extra Features For Direct3D 9 Over Vulkan

    It was just earlier this month that D9VK 0.13 was released with new features while now a "0.13f" Hypnofrog release is available in pre-release form.
