Online Word Processing – Part 3 – ONLYOFFICE

Collaborating on a text document or spreadsheet with other people and thus editing it in the browser instead of with a local application will definitely become more and more common. Collabora’s Online office solution doesn’t work s o well for me, and I won’t use a closed source solution such as Microsoft 365 online for my projects, I was of course looking for yet another solution. In addition to Collabora, Nextcloud has integrated ONLYOFFICE for a number of years now, so this is where I went next.

Online Word Processing – Part 2 – MS Office Online

In the previous episode on this topic, I’ve been taking a look at Colabora Online and word processing in the browser in combination with Nextcloud. Unfortunately, in my humble opinion, Colabora Online suffers from a number of shortcomings, that have never been fixed over the years. My main issue with the solution is that the screen is rendered on the server side, which introduces a noticeable lag, which gets worse the further away the server is located. But it seems to be an architectural decision that can’t easily be changed. So how do other online office solutions fare in this regard?

Reality Bites – Flight Simulation – Part 12 – Talk Recording – GPN21

There we go, I was at GPN21 the previous weekend and gave a talk about flying in the virtual worlds. The Video Operation Center has been quick and the recording is now online for general consumption. As it was a mostly German event, I decided to give the talk in German. Sorry about that but I guess some of you do speak the language.

The Blog Moves to MariaDB

I’m running a lot of the services I host on my own in Docker containers these days. This makes it pretty much worry free to run and update them. This blog is no exception, it’s been running in containers for two years now. But container images age as well, and from time to time one should have a look if one is still on a stream of a supported version. Case in point: The MySQL container that runs the database of this blog. So far, I’ve been using the MySQL 5.7 stream of Docker images. However, MySQL 5.7’s long term support will end in October 2023, so it was time to go to the next version. A nice quick project to do while at GPN21. It should have been be worry free, no? After all, it’s a container image. Well, not quite.

Reality Bites – Flight Simulation – Part 11 – Giving A Talk at GPN21 This Week

While I’m certainly still considering myself a newbie at flight simulation, I’ve accumulated a number of interesting stories about the topic over the last year on how to get started. So I thought I’d talk a bit about it at the upcoming ‘Gulaschprogrammiernacht’ (GPN21) in Karlsruhe this weekend. Yes, it’s not quite like any other topic I’ve talked about over the years, but I like the challenge. GPN21 is mostly a German speaking event, so most talks, including mine, will be held in German. If you can’t make it to Karlsruhe, talks will be streamed live and will be recorded for later consumption. My talk is scheduled on Saturday, 10. June 2023 at 11.10 am.

Online Word Processing – Part 1 – LibreOffice / Collabora

Over the past years, I’ve been using the Collabora Online / LibreOffice integration of my Nextcloud instance at home to collaboratively work on text documents and spreadsheets. While this works in general, there are a number of issues that have not improved for me over the years which make it difficult to encourage people to work with this setup. In this post, I will first have a look at the pain points. In follow up posts, I will then have a look if I get the same behavior when using other products such as Microsoft 365 online and Google docs.

NFC Payment in the Paris Metro

It took many many years, but I finally used an NFC payment service on a mobile device: For paying in the Paris metro! So how well does this work and how does it compare to other cities?

Digitization – More Complicated?

To me, digitization is something out of the 1980’s, but it seems to be a resurrected topic in the 2020’s. In my opinion, digitization should strive to make things simpler instead of more complicated for the customer. Unfortunately, in reality, many services that are digitized are often just as complicated or even more so than than their analog predecessors. There is one exception that comes to my mind, however, and that is how one can pay in the London metro. It’s so simple that I’ve come to see it as the ‘gold standard’ of a service that was digitized. So let’s have a look at London Transport first and then compare the system used by the Paris metro.

Reality Bites – Flight Simulation – Part 10 – Moving to ‘the Bus’

It was predictable in some way that sooner or later, I would want to do yet another ‘upgrade’ in the flight simulator and move to something bigger. After the turboprop Daher TBM-930, which I started flying last year, it was either a private yet or an airliner. There is lots of choice and in the end, I decided to go for an airliner. The big choice to make at this point then is: Airbus or Boeing!? In the end, I decided to go for an Airbus A320 and here again, there are several implementations to choose from: In the Asobo / MS flight simulator, one can choose the A320 that comes with the simulator itself, the open source FlyByWire A320neo or the closed source and not for free Fenix A320ceo. After some investigation, I came to the conclusion that I’d skip the default A320 and go straight for something with more ‘system depth’. Both the FlyByWire and the Fenix A320 seem to be fantastic products and, contrary to my open source nature, I decided to go for the Fenix A320 first. At 50 British pounds, it is very affordable and is said to have an unrivaled system depth, i.e. pretty much everything the real plane does works in the simulator as well. I have no idea how that could be done for 50 GBP, but I was eager to find out.

Wi-Fi AP Handover and Real Time Services

Earlier this year when I was on vacation in the Austrian alps, I noticed an interesting Wi-Fi behavior that I thought I should note down here for future reference: The impact of a handover from one Wi-Fi access point to another in a distributed system.

Reality Bites – Flight Simulation – Part 9 – Satellite Communication in Planes

There obviously had to come a time when the interests of the wireless network engineer in me and my enthusiasm for flying in the simulator cross paths. Even small general aviation aircraft have lots of radios on board these days and if you go up the price range a bit, there are even built-in satellite communication options available. And when moving up the scale to airliners, satellite communication for voice calls and data exchange is a standard feature. So let’s have a look at these capabilities.
