KDE and GNOME: KUnity, Presentations, GitLab and Flatpaks

  • A year as a KDE developer | The KUnity Setup

    It has been more than a year that I had push rights for all the KDE repositories. So this is an obligatory anniversary post.

    I got introduced to Linux while searching for development environments that came with all sorts of compilers & interpreters by default and I don't have to manually install those stuff. It was 2012 as far as I remember, Ubuntu 12.04 just came out and it was the first solution suggested by the search engines. Though the unavailability of a proper internet connection meant, that I had to wait a couple more years when one of my friends downloaded a copy of Ubuntu 14.04 for me.

  • FOSDEM and Plasma Mobile Sprint 2020

    This was the 20th anniversary for FOSDEM, I first attended 15 years ago, but this year was the first time I actually managed to present a talk there. The subject was, unsurprisingly, KDE Itinerary. You can find the slides and the video recording on the corresponding FOSDEM talk page.

    KDE had a very busy presence at FOSDEM, Plasma Mobile draw a lot of attention, as did efforts for truly free and user-controlled mobile platforms in general. I’m particularly happy seeing the cross-community collaborations going on in that space.

    FOSDEM is a great place to connect and coordinate with other communities, and by now that’s probably one of the main reasons for me to attend. The collaboration with Nextcloud on integrating itinerary extraction into Nextcloud Hub started there last year for example.

    FOSDEM two years ago saw the first successful flight using a KDE Itinerary rendered boarding pass, this year we had the first ever Thalys ride with a ticket presented in KDE Itinerary. We also made a bit of progress with decoding Thalys binary barcodes, more samples would help a lot here though.

  • Presentations Archive

    Some time ago I ran across remark-cmake, a CMake framework for building remark.js-based presentations. Since I’m a sucker for CMake I started using it, even if my presentations are rarely big-and-complicated enough to warrant a build-system.

    Since then I’ve submitted a few pull-requests to remark-cmake, but also given eight (8) presentations using that framework at four (4) different conferences in four countries on two continents. Current scheduling suggests that one more continent and at least four more talks will be added before summer.

  • Clean and linear history with GitLab

    Many GNOME projects still use clean and linear commit history without merge commits even after porting to GitLab. That means that each commit represents one comprehensive feature or bug fix and there are not any side branches. I am not about to discuss the pros and cons of this approach here, you can find many and many posts on this topic on the internet. I would like to explain some common issues for newcomers when using GitLab forks.

    To make some contribution, one has to create a fork of some repository, push desired changes in a new branch and create a merge request to the original project. Please be sure that the “Allows commits from members who can merge to the target branch” checkbox is checked when creating the merge request (or later using the “Edit” button on the top of the page). This is needed to simplify the consequent workflow for the contributor (and maintainers as well). One of the reasons, why this is needed is the fact, that the changes need to be often rebased before they can be merged (to ensure the linear history). Maintainers can’t do this when this feature is not enabled and have to ask contributors to do so. Another reason is that the maintainers can do some changes when the contributor needs help or doesn’t have time to do the changes itself.

  • Robocode and others

    As expressed in a previous post, I prefer to spend my free time with my kids than with technology (for technology I already have my job). However, when there is an exception to that, I do like to do some sort of smaller projects, like “porting” stuff to Flatpak.

    I did my share of Debian and RPM packaging in the past, and honestly I have never enjoyed it (for a number of reasons not really interesting for this post). But “flatpaking” stuff is completely different to me. Maybe it’s my early involvement with it, or maybe it’s my admiration for how its designed, but the feeling when making a Flatpak is of reward, rather than a chore.

WebKitGTK 2.28 Seeing Flatpak Sandbox Support, WebGL + WebAudio

  • WebKitGTK 2.28 Seeing Flatpak Sandbox Support, WebGL + WebAudio By Default

    Following this weekend's GNOME 3.36 beta, WebKitGTK 2.27.90 is available as a snapshot of this GTK-catered version of the WebKit layout engine on its path towards version 2.28.

    With WebKitGTK 2.27.90 there are many new features baking for WebKitGTK 2.28: Flatpak sandboxing support, WebGL and WebAudio are finally enabled by default in WebKitSettings, support for same-site cookies, support for the webkit-font-smoothing CSS property, support for inspecting service workers to the remote inspector, and various other changes.

Linux and Security

  • Why Not WireGuard

    The latest thing that is getting a lot of attention is WireGuard - the new shooting star in terms of VPN. But is it as great as it sounds? I would like to discuss some thoughts, have a look at the implementation and tell you why WireGuard is not a solution that will replace IPsec or OpenVPN. In this article I would like to debunk the myths. It is a long read. If you are in need of a tea of coffee, now is the time to make it. Thanks to Peter for proof-reading my chaotic thoughts. I do not want to discredit the developers of WireGuard for their efforts or for their ideas. It is a working piece of technology, but I personally think that it is being presented as something entirely different - as a replacement for IPsec and OpenVPN which it simply is not. As a side-note, I think that the media is responsible for this and not the WireGuard project itself. There has not been much positive news around the Linux kernel recently. They have reported of crushing processor vulnerabilities that have been mitigated in software, Linus Torvalds using too harsh language and just boring developer things. The scheduler or a zero-copy network stack are not very approachable topics for a glossy magazine. WireGuard is.

  • Kees Cook: security things in Linux v5.4

    Linux kernel v5.4 was released in late November. The holidays got the best of me, but better late than never!

Changing TTY prompt, font and colors

Changing colors and font in a virtual terminal isn't easy (see below). Changing colors and font in a terminal emulator, on the other hand, is just a matter of adjusting preferences in a GUI dialog. Last year, for example, I changed the color scheme in my terminal emulator. Read more

Python Programming

  • Integrating MongoDB with Python Using PyMongo

    In this post, we will dive into MongoDB as a data store from a Python perspective. To that end, we'll write a simple script to showcase what we can achieve and any benefits we can reap from it. Web applications, like many other software applications, are powered by data. The organization and storage of this data are important as they dictate how we interact with the various applications at our disposal. The kind of data handled can also have an influence on how we undertake this process. Databases allow us to organize and store this data, while also controlling how we store, access, and secure the information.

  • EuroPython 2020: Presenting our conference logo for Dublin

    The logo is inspired by the colors and symbols often associated with Ireland: the shamrock and the Celtic harp. It was again created by our designer Jessica Peña Moro from Simétriko, who had already helped us in previous years with the conference design.

  • Finding the Perfect Python Code Editor

  • PyCon: The Hatchery Returns with Nine Events!

    Since its start in 2018, the PyCon US Hatchery Program has become a fundamental part of how PyCon as a conference adapts to best serve the Python community as it grows and changes with time. In keeping with that focus on innovation, the Hatchery Program itself has continued to evolve. Initially we wanted to gauge community interest for this type of program, and in 2018 we launched our first trial program to learn more about what kind of events the community might propose. At the end of that inaugural program, we accepted the PyCon Charlas as our first Hatchery event and it has grown into a permanent track offered at PyCon US.

  • Using "python -m" in Wing 7.2

    Wing version 7.2 has been released, and the next couple Wing Tips look at some of its new features. We've already looked at reformatting with Black and YAPF and Wing 7.2's expanded support for virtualenv. Now let's look at how to set up debugging modules that need to be launched with python -m. This command line option for Python allows searching the Python Path for the name of a module or package, and then loading and executing it. This capability was introduced way back in Python 2.4, and then extended in Python 2.5 through PEP 338 . However, it only came into widespread use relatively recently, for example to launch venv, black, or other command line tools that are shipped as Python packages.

  • New Python Programmer? Learn These Concepts First.

    As a novice Python developer, the world is your oyster with regards to the type of applications that you can create. Despite its age (30 years—an eternity in tech-world terms), Python remains a dominant programming language, with companies using it for all kinds of services, platforms, and applications. For example, Python lets you create web applications via Django or other frameworks such as Flask. Perhaps you want to create games instead? For that, learn Pygame for 2D games (or Panda3D for 3D). Or maybe you’re more enterprise-minded, and want to create useful utilities (such as automatically cataloguing e-books); in that case, Python works well with frameworks and software such as Calibre.
