  • Docker swarm cheat sheet
  • in-tree annotations of third-party code (moz.yaml)
  • GSoC 2018 - First month status

    Hi all, I am Chinmoy and I am working on the GSoC project Verifying signatures of pdf files. This is my very first post and in this I intend to inform about the progress I have made since May 14.

    Now due to some unforeseen problems I had to deviate from my proposed timeline. Initially my plan was to implement all non-graphical components in the first half of coding period and in the later half implement the graphical components. But while coding RevisionManager (this would have enabled to view a signed version of document before an incremental update like Adobe Reader does) I ran into some issues while designing its API. So I postponed my work on RevisionManager and started working on the graphical components. So as a result I was able to add basic GUI support needed to verify signed PDF. The patches are listed in T8704.

  • How to Enable the Blur Effect in KDE Plasma 5.13

    The new blur effect in KDE Plasma 5.13 is wowing a lot of people, us included, but a few of you have been in touch to ask how you can enable or configure the blur on your own system.

    Plasma 5.13 should (as I understand it) come with the swish new gaussian blur effect enabled by default provided you use the Breeze theme. Provided you’re on a Linux distro that has the latest Plasma release (like KDE Neon) you should see it.

    If you don’t have it, or if you want to adjust the blur strength and opacity, read on. In this post, we’ll show you what you need to do to get it working.

Approximately 80% of the web is powered by PHP. And similarly, high number goes for SQL as well. Up until PHP version 5.5, we had the mysql_ commands for accessing mysql databases but they were eventually deprecated due to insufficient security.

KDE/Qt: Qt 3D, Kube/Kolab, GSoC, and Atelier (3-D Printing)

  • What a mesh!
    With all the advances being made in Qt 3D, we wanted to create some new examples showing some of what it can do. To get us started, we decided to use an existing learning framework, so we followed the open source Tower Defence course, which you can find at CGCookie. Being a game, it allows an interactive view of everything at work, which is very useful.
  • Last week in Kube
    Perhaps if Windows wasn’t such a PITA there would be more progress
  • GSoC 2018: Week 4 & 5
    The last 2 weeks were mainly dedicatd for reviews and testing and thanks to my mentors, I passed the first evaluation with good work till now. Some significant changes were made on discussion with my mentors during the last 2 weeks in the code and some new features.
  • Giving Atelier some Love
    I work for atelier together with Chris, Lays and Patrick for quite a while, but I was basically being the “guardian angel” of the project being invocked when anything happened or when they did not know how to proceed (are you a guardian angel of a project? we have many that need that) For instance I’v done the skeleton for the plugin system, the buildsystem and some of the modules in the interface, but nothing major as I really lacked the time and also lacked a printer.

  • Google’s VR180 Creator Makes It Easier to Edit VR Video on Linux
    It’s called “VR180 Creator” (catchy) and the tool aims to make it easier for people to edit video shot on 180-degree and 360-degree devices like the Lenovo Mirage camera (pictured opposite). And boy is just-such a tool needed! VR180 Creator: Easier VR Video Editing Editing VR video is, to be perfectly frank, a pain in the rump end. So by releasing this new, open-source tool for free Google is being rather smart.Anything that makes it easier for consumers and content creators to edit VR on something other than a high-end specialist rig is going to help the format flourish.

Devuan GNU+Linux 2.0.0 "ASCII"

When I am trying out a desktop distribution, what really tends to divide the field of Linux distributions in my mind is not whether the system uses MATE or Plasma, or whether the underlying package manager uses RPM or Deb files. What tends to leave a lasting impression with me is whether the desktop environment, its applications and controls feel like a cooperative, cohesive experience or like a jumble of individual tools that happen to be part of the same operating system. In my opinion Ubuntu running the Unity desktop and Linux Mint's Cinnamon desktop are good examples of the cohesive approach. The way openSUSE's administration tools work together provides another example. Like them or hate them, I think most people can see there is an overall design, a unifying vision, being explored with those distributions. I believe Devuan falls into the other category, presenting the user with a collection of utilities and features where some assembly is still required. This comes across in little ways. For example, many distributions ship Mozilla's Firefox web browser and the Thunderbird e-mail client together as a set, and they generally complement each other. Devuan ships Firefox, but then its counterpart is the mutt console e-mail program which feels entirely out of place with the rest of the desktop software. The PulseAudio sound mixing utility is included, but its system tray companion is not present by default. Even the system installer, which switches back and forth between graphical windows and a text console, feels more like a collection of uncoordinated prompts rather than a unified program or script. Some people may like the mix-and-match approach, but I tend to prefer distributions where it feels like the parts are fitted together to create a unified experience. What I found was that Devuan provided an experience where I had to stop and think about where items were or how I was going to use them rather than having the pieces seamlessly fit together. However, once I got the system set up in a way that was more to my liking, I appreciated the experience provided. Devuan offers a stable, flexible platform. Once I shaped the operating system a little, I found it to be fast, light and capable. Having a fairly large repository of software available along with Flatpak support provided a solid collection of applications on a conservative operating system foundation. It was a combination I liked. In short, I think Devuan has some rough edges and setting it up was an unusually long and complex experience by Linux standards. I certainly wouldn't recommend Devuan to newcomers. However, a day or two into the experience, Devuan's stability and performance made it a worthwhile journey. I think Devuan may be a good alternative to people who like running Debian or other conservative distributions such as Slackware. I suspect I may soon be running Devuan's Raspberry Pi build on my home server where its lightweight nature will be welcome.
