  • Will Thompson: Flatpak External Data Checker

    (This post is a slightly longer version of a lightning talk I gave at GUADEC 2019.)

    Many non-free applications’ binaries cannot be redistributed (particularly not in modified form), so they cannot be included directly in a Flatpak. To work around this, Flatpak supports the concept of “extra data”: files which will be downloaded and unpacked from a third-party URI when the app is installed. The URI is accompanied by a checksum and a size, to provide some hope that the data unpacked on the user’s system is the same as what the packager tested. This is used by, for example, the Dropbox Flatpak.

    Of course, the Flatpak needs to be kept up to date when new versions of the app are released. At best, the old URL will still point to the same file, so at least the old version of the app will continue to be installed; in some cases, however, vendors publish new versions of the app at the same URL, which means the Flatpak cannot be installed until it is updated.

  • When I couldn’t make it to Nuremberg Sprint 2019

    Back when I was selected as a Google Summer of Code 2019 student for my project Porting KDE Connect to Windows, it was a sheer stroke of luck when incidentally I got invited by my mentor Simon Redman, to come to the Nuremberg Mega sprint for hacking on KDE Connect with the team!

    It was an awesome opportunity, but to be able to get to the sprint, I had to travel abroad, which needs the most difficult document I had to procure till date- a Schengen VISA. There are multiple kinds of VISA- short term, long term, and some schengen states have more or less categories of short term Visa that you can apply through. You can read more about schengen VISAs here.

Disney+ streaming uses draconian DRM, avoid

First of all, as always my opinions are my own, not those of my employer. Since I have 2 children I was happy to learn that the Netherlands would be one of the first countries to get Disney+ streaming. So I subscribed for the testing period, problem all devices in my home run Fedora. I started up Firefox and was greeted with an "Error Code 83", next I tried Chrome, same thing. So I mailed the Disney helpdesk about this, explaining how Linux works fine with Netflix, AmazonPrime video and even the web-app from my local cable provider. They promised to get back to me in 24 hours, the eventually got back to me in about a week. They wrote: "We are familiar with Error 83. This often happens if you want to play Disney + via the web browser or certain devices. Our IT department working hard to solve this. In the meantime, I want to advise you to watch Disney + via the app on a phone or tablet. If this error code still occurs in a few days, you can check the help center ..." this was on September 23th.

Red Hat and IBM Leftovers

  • Why Red Hat supports standards and open source

    Red Hat may be synonymous with open source and the developer community, but the company also actively participates within industry standards processes. For example, it is working closely with the operator-led Common NFVi Telco Taskforce (CNTT), which was initiated in the LFN open source community but has now been embraced by the GSMA, as an attempt to harmonise on the many varied NFV infrastructure solutions and architectures. Furthermore, Red Hat supports the move for greater alignment in NFV software platform domain.

  • Overview of Node-RED 1.0 Release

    Low-code, visual-based programming environments are opening doors for new types of application developers. At the same time, new event-driven architectures are making such environments more responsive. Node-RED, a visual flow-based programming tool, is one such environment attuned to these new development styles. After years of refinement, the open source Node-RED recently hit maturity with a 1.0 release. I chatted with Nicholas O’Leary of IBM, who has pioneered the development of Node-RED. In this article, we’ll discover what this new release encompasses. We’ll also peek into the history of Node-RED, look into some fascinating IoT use cases and estimate the future Node-RED roadmap.
