Using OpenFrameworks was easy, it makes it fast to start developing with it but in many aspects it’s completely different from the way we’re used to work on GNOME. We are used to have single, independent libraries that do one thing and do it well and are used as needed by application developers, for example, do not include a sound library if my application is never going to use it.
Having modules such as GTK+, Clutter, Cairo, GStreamer, etc. already gives us flexible ways to develop certain parts of applications similar to the demo mentioned before: we just had to draw the fish using Clutter/Cairo, implement their behavior and show the Clutter stage. Of course we also would need a way to control the Kinect and it would be really nice if it could offer us an easy to use API for those familiar with GLib…

Ladies and gents, we give you… GFreenect

GFreenect is a wrapper for the Freenect library written using Glib in order to control a Kinect device and make it easy to use with GNOME technologies.
It doesn’t simply wrap the Freenect library but also offers ways of using it that are familiar to you if you have developed something using other GNOME libraries.
One example of this enhanced functionality is that we focused on offering an asynchronous API (although there are some synchronous alternative methods as well). Another example is that when setting the device’s tilt angle, a signal will be emitted when it has finished setting the angle, since it might be useful for some applications.

One of the purposes of having it written with GLib is the GObject Introspection capability. This allowed us to include an example application that controls the various features of the Kinect and was written in Python effortlessly. A screenshot of this app is shown below:

And that’s it! You can find the code for GFreenect in Gitorious (including documentation for this 0.1.2 version). Bear with us if you find some bugs, it is fresh out of the oven.

We hope you find GFreenect useful for your projects and please give us feedback if you find some issues or have any good suggestions.

This summer Micke Prag, a fellow programmer from Sweden contacted me because he was starting a port of SF for Harmattan. By then I still didn’t have an N950 because of having missed the deadline for the first developers program. Later, when the second developers program was launched I managed to finally get one. At that point, even though I already had my Samsung Galaxy S (yes, with Android) I still wanted to have a port of SeriesFinale as I had received many emails asking for this port so I started from Micke’s code and finally here it is!

The Harmattan port

Maybe it is something obvious but this version is not written in PyGTK/PyMaemo. It uses part of the “old” Python backend that was changed to play well with the new UI code written in QML.

In this release one thing I wanted to improve was the startup time. With the number of TV shows I have in my SF, it was taking around 25 seconds before showing me the list of shows. Part of this is due to the deserialization from the DB (no, it’s not using SQLite and I have no time to make the switch) which takes its time but also because it was attempting to sort the list of shows every time a show was added and it also took some time loading the shows’ covers from disk.
This fix was basically loading of the covers asynchronously and sorting the shows only after they are added to the tree view. It improved from 25 seconds to 12 seconds more or less.

While the shows’ covers are being loaded on startup or downloaded from the web, it displays something like shown on the following screenshot:

One of the features people like more is the display of the next episode’s air date. To improve this, I’ve added a small tweak to humanize the dates close to today so it displays “Yesterday” instead of “20 Jul”.

The covers retrieval was broken for a while and this is fixed too. What happened was that TheTVDB started redirecting images to a mirror and SF was not following redirected links… It should follow them now, so it is unlikely to happen again.
I’m also including the French translation kindly sent by David Landreau.

Other important improvements and fixes are:
* Fix deleting seasons;
* Add sorting options to the seasons view;
* Fix infinite loop when updating episodes (it happened when there were two shows with the same name);
* Consider next episode to watch only when it has an air date;

There are also some good news from other platforms’ ports. Nacho has created a branch where he is porting the GNOME version to GTK3/PyGI. A user named Micke Prag is porting it to QML which means it will be available on MeeGo one of these days. I wanted to apply for the developer’s N950 program (to port SF) but I was on honey-moon when it was announced and I ended up forgetting about it…

Revenge of the clones

When I first developed SF in 2009, I did it to scratch an itch and I couldn’t find such an app when I googled for it, I even wondered if anyone apart from me would be interested in such an app. Short after, my friend and colleague from the University, Paulo Cabido told me how much he liked the idea and created DroidSeries, a SF’s clone for Android. After a while I also found SeriesWatcher, a clone in Qt that also ran on the Linux desktop, Windows and Mac OSX.
What surprised me was that last week I was browsing the Android Market (out of curiosity, I don’t own an Android phone) and found out that there are:
* Series Droid (notice the name? If my friend Paulo was M$ or Apple, he would sue their asses )
* TV Show Favs
* TV Start
* Episode Calendar (this seems to be the only Open Source one in the list)

Although only DroidSeries and SeriesWatcher say they are based in SF, I like to think the others do as well (maybe indirectly like being based on another clone ). Or maybe those were developed before SF and I didn’t notice… What I’m trying to say is that not only from mainstream platforms come nice end user apps. In the Maemo world, even though we have problems of other nature, we also have good ideas and good applications for end user.

Get SeriesFinale 0.6.8 soon from your N900′s updates or here.

The highlights for this new version are:

Add plain text exportation

Sometimes users just want to get the plain text from a scanned document and this is especially useful for visually impaired users that will be able to read the text files with Orca afterwards.
This feature was developed by Andrew McGrath, a student from New Hampshire, who is contributing to OCRFeeder as part of his involvement in the Software for Humanity project. It would be great to have more colleges involved in this kind of initiatives.

Recognize the current page or the whole document

Now it is possible to automatically recognize the current page (as it did before) or the complete document. I’ve also added a confirmation dialog before the recognition is performed when there are changes in the project.

Thanks also to Joanmarie for all the great suggestions like this one and to Juanje Ojeda for the patches he sent me.

These were just the two main features I’ve picked from the list of changes, to view them all check the NEWS file.

Stay tuned for more improvements in the future.

This version’s highlights are:

* Live search of shows. Finally it includes a way to quickly filter shows, this is especially useful for those who have a large number of shows in the list.

* Quick access to the next/previous episodes. This was another request from a user, when viewing an episode, add a way to quickly go to the previous or next episode. I have added this by panning/dragging horizontally in the episode view, dragging left or right will bring the next or the previous episode, respectively.

* Switched episodes’ “watched” check-boxes to the right. After adding the portrait mode, it was clear that having the episodes’ check-boxes on the right made more sense for right-handed people. This is now the default position, nevertheless, a new option was included in the settings dialog so users can choose to either have on the right or left.

* Last but not least, Juan has made SF more reliable and fast by saving the database and settings only if they have been changed.

We will keep the list of bugs and feature requests in mind for the SF development (for both Maemo and GNOME) so, you are welcome to submit more.
