Coder's Log

Last week, I had the pleasure of attending the 4th GNOME+Rust hackfest in Thessaloniki, Greece. While other folks were mainly focused on the infrastructure work , with my Rust being extremely rusty as of late, I decided to do something that tests the infra instead. More specifically, I took up on Sebastian's challenge of "Maybe someone should write a gst-inspect replacement in Rust". I am happy to report that by the end of the hackfest, I already have an implementation that covers 30% of the typical usage of gst-inspect. This implementation also comes pre-built with paging by default (which I only recently added to the current gst-inspect) and colored output ( MR on existing gst-inspect still pending review). I did run into some rather interesting issues though but there was always someone who could help me out. One specific one was on how best to pipe the output in Rust to a pager. This took more than a day and my implementation was mostly very similar to the one I

Just wanted to announce release 2.5.0 of Geoclue that includes the changes I mentioned in my last blog post . Also, while I'm at it, I wanted to highlight the "call for help" at the end of that post by repeating it here again. I apologize of repeating to those who already read it but a friend pointed out that it's likely going to be missed by many folks: The future of Mozilla Location Service When Mozilla announced their location service in late 2013, Geoclue became one of its first users as it was our only hope for a reliable WiFi-geolocation source. We couldn't use Google's service as their ToC don't allow it to be used in an open source project (I recall some clause that it can only be used with Google Maps and not any other Map software). Mozilla Location Service (MLS) was a huge success in terms of people contributing WiFi data to it. I've been to quite a few places around Europe and North America in the last few years and I haven

After I started working for Collabora in April, I've finally been able to put some time on maintenance and development of Geoclue again. While I've fixed quite a few issues on the backlog, there has been some significant changes as of late, that I felt deserves some highlighting. Hence this blog post. Leaving security to where it belongs   Since people's location is a very sensitive piece of information, security of this information had been the core part of Geoclue2 design. The idea was (and still is) to only allow apps access to user's location with their explicit permission (that they could easily revoke later). When Geoclue2 was designed and then developed, we didn't have Flatpak . Surely, people were talking about the need for something like Flatpak but even with those ideas, it wasn't clear how location access will be handled. Hence we decided for geoclue to handle this itself, through an external app authorizing agent and implemented such an agent

Earlier this month, a few of us from Collabora, Olivier Crête, Nicolas Dufresne, George Kiagiadakis and I attended the GStreamer Spring Hackfest in Lund, Sweden. Hosted by  Axis Communications (who uses GStreamer in their surveillance cameras for many years now), it was a great opportunity for the GStreamer community to touch base and work on open bugs and pet projects. While I've been involved in the GStreamer project in the past, it was my first GStreamer hackfest. While a lot was achieved during the event, the most exciting outcomes were no doubt the closing of more than 350 bugs, and the agreement on a transition plan to move to GitLab. Overall, the hackfest was very productive, with each member of our team managing to progress in their list of tasks while all taking part in bug triaging & cleaning in preparation of moving GStreamer's issue tracking to GitLab. George spent time working on improving the new library API that is needed to introduce

Last Thursday was my last day at Kinvolk . While Kinvolk is a great company run by very nice and talented folks and I really hoped to work there for a very long time, unfortunately it turned out to be not the best fit for me. While I am sad to leave, I am also very excited to join Collabora in their multimedia team. Today is my first day there. Since Collabora does not exist in Germany, I will be working for them as a consultant and had to register my own one-man company. Yes, I will be staying in Berlin and work from home. I have known Collabora from its very early days, when it was just a few developers with a vision and passion for Open Source. I also worked very closely with Collabora over the years during the good old Nokia Maemo/Meego times. I always had great appreciation for their work and commitment to Open Source, which is a huge challenge for a consulting company. While I do not yet know which specific projects I will be involved in at Collabora, I'm most likely

As most folks who know me already know, I've been in love with Rust language for a few years now and in the last year I've been actively coding in Rust. I wanted to document my journey to how I came to love this programming language, in hope that it will help people to see the value Rust brings to the world of software but if not, it would be nice to have my reason documented for my own sake. When I started my professional career as a programmer 16 years ago, I knew some C, C++, Java and a bit of x86 assembly but it didn't take long before I completely forgot most of what I knew of C++ and Java, and completely focused on C. There were a few difference reasons that contributed to that: Working with very limited embedded systems (I'm talking 8051 ) at that time, I quickly became obsessed with performance and C was my best bet if I didn't want to write all my code in assembly. Shortly before I graduated, I got involved in GStreamer project and beca

I have been meaning to document my experience of moving to Berlin, mainly to help people who are considering to move or are about to move. However I'm lazy and unless I'm paid to do so, I just won't get around to doing that so instead of ending up posting nothing, I'll just quickly list all the advice I have here: Don't actually order any services through check24 website. Only use them to compare prices etc. Avoid Vodafone for broadband connection. Follow this thread for why. Consider using an online bank, like N26. For your Anmeldung, go to Bürgeramt in Neukölln or Kreuzberg (unless you speak German). book appointment around noon or be prepared to wait a month. Make sure you have local friends who speak German and are willing to help you out. Many locals will tell you that you don't need German in Berlin but that is simply not true. Either consider hiring an estate agent or make sure your temporary residence allows you to register on their address
