Diving at Anacapa, one of the Channel Islands off the coast of Southern California, was one of the more exciting dives I did last year. I've just come across this nice video, which gives an excellent impression of how awesome diving through a kelp forest can be like. Would totally recommend, if you ever get the chance to do it and feel confident enough (it is, after all, an open ocean dive in temperate water, with possible entanglement danger).

There seem to be (artificial) kelp plantations in the Netherlands as well, but I couldn't find a contact or location for them, yet. If you happen to know something about it (or are really good at this kind of detective work), I'd love to hear about it. It would be quite awesome to be able to dive kelp right here at home... :)

When I was there, last year in June, we had 7-10m, pretty OK, especially as the kelp gives you some impression of space.

We visited the CMS experiment right now, which shoots small things at each other at really high speeds. It's an awesome machine, so I blogged about it.
We visited the CMS today, the Compact Muon Selenoid, one of the “experiments” that are part of the LHC, the large hadron collider, which is a research project aiming to find out more about the basic structures that make up our universe, like how gravity works, which particles make up our ...

For the first time, the majority of the developers at this Plasma sprint is now working in a Wayland session, dogfeeding.

Well, we're not switching Plasma to Wayland, we are adding support for using the Wayland protocol for a Plasma session, that's a subtle but very important difference. We're in fact doing the exact opposite of imposing X11 on people.

The reason why I used "feeding" instead of "fooding" is boringly mundane, though: I'm a grammar nazi. :P

Being an avid scuba diver, I helped out a bit with Subsurface Mobile, a dive log application you can use on the go, and the little sister of the Subsurface desktop app, a popular Free software dive log application.

We kept the feature set of this first version limited as to create a stable base to work on top of, and it already works quite well for viewing, quickly editing a dive, GPS tracking and a few other things. It syncs with the desktop app through a custom cloud service.

Much thanks goes out to +Dirk Hohndel who has been tirelessly working on getting this baby off the ground, and who has been a great mentor when getting started with subsurface hacking.
 
Subsurface-mobile for Android -- first beta

The Subsurface developer team is thrilled to announce the first beta release of our mobile app for Android.

Subsurface-mobile connects to your Subsurface cloud storage account and allows you to access your dive list from your mobile device. You can scroll through your dives, look at dive details and dive profiles, edit dives, even add new dives on your phone or tablet. After an initial sync Subsurface-mobile works offline, so no worries about being on a dive boat and not able to connect to the network - the data will be synced at the next opportunity when you are back within signal range.

Subsurface-mobile also includes the GPS tracking functionality of the old Subsurface companion app which allows you to collect precise GPS fixes for your dive sites.

At this point Subsurface-mobile will be most useful when used together with the existing Subsurface desktop application. Most notably, downloading dives from your dive computer is so far not possible from Subsurface-mobile (but that is on our to-do list for at least some classes of dive computers).

In order to try Subsurface mobile on your Android device simply opt in at this link: https://play.google.com/apps/testing/org.subsurfacedivelog.mobile

And don't forget to take a look at the user manual
For this BETA release it is critical that users report any problems with the use of the mobile software. After all, one of the objectives of a beta release is to distribute the software to a broader circle of users using different Android devices and configurations in order to iron out any bugs, ...

In March, the yearly meeting of KDE's Plasma team was held in Geneva, kindly hosted by the European Centre for Nuclear Research (CERN). In-person meetings provide unique opportunities to work together face-to-face, at high bandwidth to tackle problems together and plan for the future. As there were some other groups present during this meeting, notably the visual design group and the Wiki cleanup team, there was ample opportunity to think outside...

So we're closing the Plasma sprint at CERN, simultaneously, half-way around the world, +Dirk Hohndel releases the first stable version of Subsurface Mobile, being the first application that uses the Kirigami components (a set of Plasma-based UI components) for its UI. The timing couldn't be better.

Congrats, Subsurface, congrats Plasma, and thanks everybody!
 
Announcing Subsurface-mobile for Android

The Subsurface development team proudly announces the first release (version 1.0.2) of Subsurface-mobile for Android, an open source dive log for phones and tablets.

This release is the result of all of our work on Subsurface and a year long development effort towards a mobile user interface that is optimized for phones and tablets. We got tremendous help from the KDE community to get us to this first release. Subsurface-mobile is the first application that implements the Kirigami UI using the Kirigami Controls by KDE.

Subsurface-mobile gives you access to your dive data on your mobile device. Simply store your dive data from the Subsurface desktop application in the Subsurface cloud and access it on your tablet or phone with the same credentials. This way your dive data are seamlessly shared between your computer at home and your mobile device. Regardless where you make changes to your data, they are synced and visible the next time you connect from any computer or device.
You can scroll through your dive list and view dive details for individual dives. You can edit many of these details right on the device and even manually add new dives.

At this point Subsurface-mobile is best used together with the Subsurface desktop application. As we continue our development we plan to make the mobile application even more useful by itself -- especially once we are able to download dive data directly from (some) dive computers. Right now you still need the Subsurface desktop application for this.

Subsurface-mobile can track your GPS locations on dive trips (and replaces the old Subsurface companion app that some of you may have used in the past for that purpose) and can show the location of dive sites on a map.

Subsurface-mobile is available in the Google Play store.
https://play.google.com/store/apps/details?id=org.subsurfacedivelog.mobile

For those who don’t have access to Google Play, you can download the APK directly from our server to your device as well. Please use this link from your Android device and install the APK after it finished downloading. If you haven’t enabled installation from “unknown sources” your device will present a warning to that effect. https://subsurface-divelog.org/downloads/Subsurface-mobile-1.0.2.arm.apk

Please check the user manual https://subsurface-divelog.org/documentation/subsurface-mobile-user-manual/ for details on how to get started and report any issues that you find on our user forum https://subsurface-divelog.org/user-forum/

An iOS version of Subsurface-mobile is also under development, we expect to start alpha testing it within the next few weeks.
Subsurface is a free open source dive log application available on Windows,...

I mentioned LTS to state that during 6 or so years of its life users are bound to 4 versions-old Calligra (LibreOffice as well, for that matter). Backports to kdelibs4 are not going to help with that.

I am not complaining about the gui, (that's not a public message after all?) but stating a similar humorous note like Sebastian --  that on desktops of my users there is a text says about KDE crashes and people believe in it. Stated that as an example of how easily I can overlook details. I, because if I knew I'd fix it myself in 4.2 era :)

PS: Why do you think tabbed toolbar is a rippoff of ribbon? Do you know the story?
State-based UIs are more popular than in the year you discovered it. Qt Creator uses some form of it (just vertical) as well as Kontact and somehow - KDevelop. All such complex apps have challenges. Calligra uses vertical collapsible panes that are clearly alternative to tabs. If you look closer, many KDE apps use the concept. BTW wide-screen displays won the market so Kexi will move the ribbon to something more like Creator or Kontact or JIRA.

Re. HIG - it's is a suggestion, so you won't easily codify how to make a GUI simple for an advanced app that is not a plain text editor.
Good that there are no longer KDE apps - just Qt apps - because of the utopic attempt to align to current style they were not compliant with non-Plasma desktops they were running on. KDE HIG nor any other HIGs define how to align to other desktop's HIGs so it's useful as long as your choice of desktop is KDE HIG-compatible. If your users are elsewhere, applicability of given desktop's HIG is less than average. Borsers, position of panes, menus, existence of icons, size of buttons, fonts, all this is out of the scope of QStyle/QQCS and our of scope of any document.

I just pushed the third (and hopefully final) beta of Subsurface-mobile for Android to Google Play. For those who installed an earlier beta version they should see an update, soon. If you haven't played with this but would like to give it a try, simply opt in at this link: https://play.google.com/apps/testing/org.subsurfacedivelog.mobile

This beta has what should be the final UI - menus open with the arrow buttons in the lower corners (much easier to reach with your fingers when holding the device), the action button consistently saves / confirms actions, the Android back button is used to go back / abort actions. Editing / manually adding dives works, as does tracking GPS locations. Overall interaction with the dive list is much smoother and there is even an option to delete a dive.

As always, we are of course very interested in feedback. Feedback here is ok, but we much prefer feedback in our user forum https://subsurface-divelog.org/user-forum/ or on our developer mailing list (mailto:subsurface@subsurface-divelog.org)
We plan to incorporate the feedback we get from this beta version over the next couple of weeks, finish the user manual and have a first official release later this month.

For those interested in the toolkit we used to build this application: we use Qt / QML / and the Kirigami Components that were developed by the Plasma team. A special thanks to +Sebastian Kügler and +Marco Martin for their help it getting both Subsurface-mobile and the Kirigami Components to the point they are at now. And to +Thomas Pfeiffer for his help in creating our current user interactions.

Oh, and before you ask: yes, we are working on an iOS version. Thanks to +Tomaz Canabrava we have a very early first build that is not quite functional, yet, but we should be able to start a beta test for the iOS version after the Android version has been released.
