Sailfish Community News, 9th February, Yrityspäivät

Sailfish OS update from Jolla

It’s February and time sure is flying by! We’ve been busy bees preparing for the Sailfish OS 4.5 “Struven ketju” release which is currently in Early Access phase. We’re hoping to make it publicly available this week so everyone can enjoy the fruits of our labor. Make sure to keep an eye on Jolla’s blog as well, as we will be posting a comprehensive article about the release once it becomes accessible to all.

(Note: Shortly after publishing this Community News, Sailfish OS 4.5 became available for all. Read more about the release: Sailfish OS 4.5 ‘Struven ketju’ blog post)

We also wanted to remind you that to celebrate the Sailfish OS 4.5 release, we have a limited time only Sailfish X for 39,90€ campaign at the Jolla Shop. Now’s a great time to buy your Sailfish OS license if you haven’t already.

Aside from Sailfish OS 4.5, we participated in two events in early February. On February 2nd, we had the pleasure of meeting students at Yrityspäivät (Enterprise Days), the most popular student contact and recruitment event in Tampere. We had some interesting discussions and got to showcase Jolla and its products as well as AppSupport for Automotive demo, that gained a lot of attention. It was an excellent event and we’ll definitely be back next year.

A few days after Yrityspäivät, we headed to Brussels for Fosdem. We had two talks - Björn Bidar (thaodan) presented “Sailing into the Linux port with Sony Open Devices,” and David Llewellyn-Jones (flypig) spoke about “Covid Exposure Notification Out in the Open.” We believe both presentations resonated well with the audience.

We also had a busy “Linux on Mobile” joint stand with postmarketOS, Mobian, and Ubuntu Touch. It was great to see so many people interested in Linux-based mobile operating systems and experiencing them for themselves. Thanks to our fellow co-exhibitors at the stand for making it a success!

There were many Sailfish OS users who travelled to FOSDEM, came to see us on our stand, attended the Sailfish dinner, watched the talks and joined the Sailfish Birds of a Feather Q&A event. It was wonderful to meet you all, as well as to talk to many potential Sailfish OS users as well.

One of those present was special reporter and community member Nico Cartron (ncartron), who has promised to let us share his experiences of FOSDEM in a future newsletter. Thanks also to Andrea Bernabei (faenil) for letting us use the lovely picture of the our stand below.

Special Thanks to David:

And finally, but certainly not least, you may have noticed already a change in the tone of voice in this newsletter. David (flypig) has been writing this newsletter for many years, putting in a lot of effort to deliver the latest information and engaging content to our community. However, David is now moving on to new adventures from Jolla and will be passing on the newsletter writing reins. But don’t worry, David has promised to remain an active member of the community and will still be contributing to the newsletter in some capacity. A big thank you to David for everything!

Energy from the Community


As some of you may have noticed from discussions on the forum, there has been some exciting work being done to create a non-profit association to support Sailfish OS activities.

Through the efforts of the founders jojo, vlagged and fridlmue, in combination with the early members who supported the process, namely poetaster, sebix and yajo10, the association is nearly ready to go live.

Prior to the official announcement, we asked jojo to explain a little about what the association is, what plans they have for it, and how other members of the community might contribute in the future. Here’s what jojo had to say.

Sailmates is a non-profit association aiming to support and promote free and open source mobile operating system alternatives. The statutes of the association were written by the Sailfish OS community. We aim to provide help (financially and technically) to projects related to Sailfish OS. We are also a structure that can be used to apply for development grants, such as those from for funding access to third party APIs.

The association will have a board of members, organizing the day to day life of the association, and the members, that will vote during assemblies for the topics they find interesting to invest into. We will also be in need of two auditors to double check the finances of the association, since this is a requirement of Austrian law.

Once up and running the association will be looking to the community for input: ideas for projects, memberships/donations for financing projects and volunteers to build the environment around and manage the association. Let’s take a practical example, it was mentioned that having a NextCloud instance somewhere would be useful for users to be able to save their data to. Well, the association is a perfect way to do so. The association would pay for the server where it’s hosted, but we would also need members to manage the server, set things up, apply updates, perform user management and so on. There you have it: ideas, money and effort all being used. But for the non-technical members, there would of course be non-technical tasks for which we’d also need volunteers, such as finding grants that might fund projects and helping apply for it.

The next steps will be the announcement of the association, announcement of the challenge associated with it, integrating the new members in to the association and replying to the questions they have.

We’re expecting the first official announcement to happen before the end of the month, after which things will really get rolling, so stay tuned for all the info.

Camera2 API efforts

As many of you will know, when the Xperia 10 III was released, we noted a couple of areas with room for improvement, hoping that the community might be able to help. One of those areas was the Camera, where we hoped to switch to the Camera2 API to make use of the full set of all three hardware cameras available.

We’re really happy that Matko (mjun) has risen to the challenge and has started looking at how to amend the code to switch to the updated API. Matko has asked for input in some specific areas on the forum, so we’d urge anyone interested in contributing to join the discussion.

Repository roundup

Now that 4.5.0 has been published and will become available for everyone after the early access period, many repositories are updated with latest upstream versions, like the update of the C library that is worked on. Control of media playing from QML is also receiving a lot of attention with various pull requests fixing bugs in mpris-amber .

App roundup

As always we’ve tried to look at a range of different apps this fortnight: mostly apps of the useful variety, but also a game. Apart from all being examples of nicely working apps, another thing they have in common is that while they’re not all new to the world, this is the first time they’ve all appeared in the newsletter.


When I first moved to Finland I was surprised to see every parking space adorned with a small electric outlet attached to a pole. It took me more than a year to realise that these weren’t all electric car charging stations, but rather outlets for powering the car heater, before the engine is turned on. Pre-heating may not be necessary everywhere, but in Tampere, where the average maximum temperature in February is -4°C, it’s an essential part of many people’s daily routine.

Tolppa-apuri by Tero Siironen is a small app to help you figure out what time you should set the heater to activate. The outlets are set on a timer so that you can leave your car plugged in overnight, but figuring out exactly when to start the heating can require a bit of numerical dexterity. Tolppa-apuri takes the pain out of this by doing it for you.

The app is simple to use: just drag the hour and minute sliders to set the correct time when you plan to leave in the morning. The app decides when you need to set the timer to start based on the heating delay and any other factors, such as changes in daylight saving time. It then displays exactly how you need to set the circular timer switch in order to get the heating you need.

You can easily switch between two different timer styles, and there’s a cute animations when you do. On a device with a higher resolution display it would be nice if the images could be shown a bit larger, but it’s a minor gripe. Overall, the app works nicely. The latest release brings the app to version 1.2.3 with some minor tweaks especially to the About page, and it’s available from the Jolla Store.


The first version of Pipes was released by its author, Arkadiusz Kozdra (Arusekk), back in June 2022, but somehow the review we planned back then got stuck in the system. Rather ironic, given that Pipes is a game about ensuring everything flows smoothly through the system.

I’ve played many pipe games, from the eighties classic Pipe Mania to the Pipe Dream hacking minigame of BioShock, but in most cases it’s just about getting whatever the stuff is in the pipes from one place to the other. This is the first game where you have to get the contents to all parts of the playing board.

The game never explains what’s actually in the pipes, so lets refer to it as ooze. It’s probably ooze right? So the board is made up of a grid, with each tile containing one of five different tiles. As the player you have the ability to spin each of the tiles into any of its four rotations. Ooze originates in the centre of the board, and any pipes connected either directly, or via some other pipe, will fill up with ooze.

The game is clever in that you can choose how taxing you want to make it: randomly click on tiles to see if you make progress, or carefully plan a solution based on the rules of thumb and conventions that you build up over time while playing it.

It’s a fun game and an effective way to pass the time. According to the author, every level is solvable… “Even that hard one you are currently struggling with.”

The latest update adds Swedish translations, bringing it to version 1.1.1. It’s available from the Jolla Store.


We’ve covered quite a few weather apps in the newsletter, with differing purposes and covering differing areas of the world. Welkweer by Arno Dekker (ade) is one you should think about using if you’re in the Netherlands.

Opening the app immediately brings you to a summary page, perfect for getting the quick summary needed to decide whether or not to hang the washing out. You can then drill down into several subsections covering rain, temperature, wind, visibility, forecasts and alarms. Each of these sections is then split into further sections, and selecting one will often bring up a map of the Netherlands with your chosen data overlaid. In total there are no less than fifty different views, each giving a useful insight into different aspects of the weather.

The latest release brings the app to version 0.31, which switches to using the Sailfish WebView, as well as adding new views, warning notifications, Sailjail support and improvements to the user interface layout.

If you’re interested in Dutch weather then this is a great and comprehensive little app, available from both the Jolla Store and OpenRepos.


The final app in our roundup today is another we’ve not covered before. ExRates from Flo (Sikarjan) is the perfect companion if you’re travelling between countries with different currencies. It allows you to convert between any pair from a list of over 150 different countries ranging all the way from the Afghan Afghani to the Zambian Kwacha.

In order to support all these different currencies the app queries two separate APIs, with exchange rates being updated daily. Each of the currencies is presented with the flag of the country, and while it’s a bit of a burden having to scroll through to find the right currency, there is an optional search field that simplifies things a lot.

Another nice feature is that you set the “base” currently separately, optimising for converting from one type of currency to many others.

The app is nicely presented, with the latest update moving to the new backend API provided by API. You may have to manually switch API to find the specific currency you want, although in practice both APIs have broad coverage.

Version 1.7.1 of ExRates is available from the Jolla Store.

Please feed us your news

Exciting things happening in the Sailfish community. We hope that you enjoyed once again this fortnight’s community news :+1:.

And do also join us at our next community meeting, to be held on the 16th February on IRC, Matrix and Telegram.


Good luck in your new adventures @flypig !


Thank you @jojo :smiley: And good luck with your Sailmates adventures! I’ll be thinking hard about how I might be able to contribute to it.


@flypig you will be missed! Thank you for your astounding work around Sailfish and our community. I hope your new adventures will be fun and wish you all the best!


Yes, we will miss your newsletters and your positive engagement! Good luck with your new ventures.

Thank you @PeperJohnny, @poetaster. I’ll still be hanging around in the forum and in the community in general, so you’ve not totally gotten rid of me I’m afraid :grinning:


That is great news :slight_smile: Can you share what you are going to do, employment wise? I’m still adrift wondering what I should do. Maths are attractive, if only I possessed the talent :-<


With your talent, and unquestionable drive, I’ve no doubt you’ll succeed brilliantly at whatever you choose to put your mind to.

My new role is working on research projects, but still programming (thanks for the interest :smiley: I’ll fill out more detail on my personal website over the weekend).

But I’m still hoping to devote time to Sailfish OS development of course (my apps really need a bit of love, for example).


Thank you for mentioning me and believing that I can pull this off but at this point the credit is premature. Looks like @mal is already working on this so currently credit should go to @mal. I’ll definitely do whatever I can to help.


You’re too kind. Today, after repairing some of the very old hammer springs on my piano, I came to the conclusion that I will never be a concert pianist :wink:

Looking forward to hearing more!


So long @flypig, and thanks for all the Sailfish!


@flypig All the best wishes from me wherever your journey will take you. It was a pleasure reading the community news about SailfishOS and I’m very excited to see who will follow in your footsteps (the bars are laid quite high for your successor :wink:).

Cheers, the next drink is on me :beers:


Research at the British library. Oh, man. I’m so friggin jealous. Boo. Hoo. Me. :wink:

EDIT: Turing Institute at the British Library. Just to put a point on it.
