The PyGTK team is pleased to announce the return of the highly popular all-in-one installer for Windows.
The PyGTK All-in-one installer provides an alternative installation method for PyGTK users on Windows. It bundles PyGTK, PyGObject, PyCairo, PyGtkSourceView2, PyGooCanvas, PyRsvg, the gtk+-bundle and Glade in one handy installer.
Currently 32 bit Python 2.6 and 2.7 versions are supported on Windows XP and above.
Dieter Verfaillie deserves enormous thanks for this work. Firstly, he performed the tedious job of ensuring that all the component MSI installers were exactly correct, and secondly, the really difficult task of deconstructing these individual installers and reassembling their contents into a single cohesive executable.
This is a true all-in-one installer, it does not simply call out to launch the individual MSI files.
More screenshots here.
Please file bugs as appropriate.
We are looking to collaborate with others who want to create gtk+ (and friends) all-in-one installers for Windows. We anticipate the tools to generate these installers will move to GNOME in future - perhaps in a common repository. Suggestions and feedback welcome.

I'm hacking on the new Kinect at the moment and the OpenGL viewer didn't work for me so I threw together this terrible quality gtk+ one. I'll clean up the code and try to get this into OpenKinect ASAP.

I recently made a number of improvements to osm-gps-map, the easy to use mapping widget. The motivation for these came at the request of the foxtrotGPS developers (foxtrotGPS is a community developed fork of TangoGPS). These changes enhanced the API for adding images and tracks to the map, and in addition allowed me to clean up the basic API making it easier to use for the common case. But, there is more, especially relevant to Gtk+/GNOME 3.0.

After two complete rewrites following my initial experiments, the other gloobus developers (badchoice and kitkat) have continued to work on integrating this coverflow view into nautilus.
The implementation of the coverflow widget this time is a little more sane. It is passed a GtkTreeModel of GFiles, and basically does everything in isolation. The coupling to nautilus is quite loose, so the idea is that the widget can be reused easily by others.
The code is available from the linked blog post, or from github.

I had two days off while I moved offices, so I got a chance to catch up on my backlog of random hacking.
I released osm-gps-map v0.5.0 which adds a few new features (such as keyboard navigation) but also contains many bugfixes and performance improvements. Check the release notes for more information. The next item on the TODO is merging the OSD/layers branch.
I released Conduit 0.3.17 which was long overdue. Mostly a bugfix release and updating to new API. The Conduit homepage has also moved to live.gnome.org. Progress on Conduit is a bit slow at the moment, it does everything I want it to (I have a budget cellphone so phone synce does not interest me), and is pretty stable. I have some SOC work I would like to merge, but basically I am looking for developers and inspiration...
PyGTK for Windows
I finished off the fixes to build correct PyGTK+ installers on windows, hopefully closing bug #589671. I uploaded new installers with the fixes people have reported. I expect these installers to become the 'final' installers at some point. Feedback welcome.
I wanted to play with the new client side windows work in Gtk+, so I ported the effects gtk-demo to Python. This required a bit of ctypes magic to access the new API (good), and some more ctypes magic to interact with new signals that appears to have unfriendly prototypes (not so good, bug filed here).

It has been a long time between blogs. I thought I should talk about the piece of software that has been responsible for the most emails in my inbox over the last few days - osm-gps-map, the Gtk+ based map widget. What started as a widget for use in one small application of mine has grown considerably.
I recently released 0.4.0, a bugfix release.
I created a mailing list, if you are a user or interested osm-gps-map, them please join.
But I thought I should take some time to highlight some of the most interesting users of osm-gps-map, particualry those users on the Maemo platform.
Maep, OSM2Go and GPXView (by Till Harbaum)
BrainStorm (by Adam Boggs)
- BrainStorm is a storm chasing application that plots your track, and overlays current radar and severe warning imagery on the map.
- eCoach is an application for recording and managing sport activities with Nokia N900, it records heart rate data from various monitors, and plots your path on the map as you exercise.
With the help of these users, the future of osm-gps-map looks very positive.
I am currently working on merging Till's improvements to master to discourage people from copying osm-gps-map source into their application.
If you are a user of osm-gps-map and I have forgotten you then I am sorry. Please contact me and join the osm-gps-map mailing list.

Some of you out there might be familiar with Gloobus. Over the last few nights I spent some time integrating Gloobus inside nautilus.
This is a proof of concept. I have done very little so far - it shows the first 8 files in the directory, and allows you to navigate between them with animation. It is mostly just a port of Gloobus from C++ into a ClutterGroup derived Actor in C, most of the thanks should go to the Gloobus author.
It features the same bugs as Gloobus, like poor support for resizing the window, positioning bugs, and it does not scale to very many files. It also leaks like a sieve (that one's on me). Here is my inadequacy represented in video form.
Those of you who regularly work with computers and other technology will be aware of how important it is to have a good quality internet connection. If you are looking into getting a new broadband connection then I recommend you look at O2 uk broadband reviews.
However, if you would still like to take a look and perhaps fix all the bugs, the steps for testing it are
Download nautilus from my Git repository (the clutter branch)
Build the test program
make -f Makefile.covflow && ./test-covflow
Built nautilus with --enable-clutter-view
Run the newly build nautilus
This is very early work so the standard disclaimers apply. I needed to get this off my chest so I could get back to PhD work.

I made a new April resolution to start blogging reguarly again. The first step of that long journey begins now.
OpenStreetMap GPS Mapping Widget - 0.3
I just released v0.3 of osm-gps-map, the easy to use Gtk+ mapping widget. Highlights for this release include;
A new major contributor, Alberto Mardegan, who worked on many of the new features of this release. Thanks a lot Alberto!
Draw map tracks with Cairo by default.
Interpolate between zoom levels while waiting for a tile to download.
Stop using GET_PRIVATE, and cache priv* for performance.
Keep an extra border of images offscreen for smoother scrolling at the edges of the map.
Keep the last N tiles in memory to improve render performance (previously they were loaded from disk)
Add some new api; osm_gps_set_center, osm_gps_map_scroll.
Hacking on Conduit continues, with much happyness for two reasons;
GNOME has moved to git! Wahoo! I owe the sysadmin team many beers, except for Jc2k who I know could not handle them anyway.
Conduit got a SOC project, congratulations Alexandre!
Work is ongoing to merge in the new configuration and settings serialization code.
More on this later, I promise...

As was the theme of yesterdays post, here comes some more software that I have hacked on recently and can now be found on Github.
osm-gps-map is a Gtk+ widget (and Python bindings) that when given GPS co-ordinates, draws a GPS track, and points of interest on a moving map display. It Currently supports a number of different mapping sources;
It also has the following features
Intelligent caching of maps, including the ability to request a specific area of the map to be cached ahead of time
Recording of points of interest on the map (and the ability to add arbitary pixmaps at those points
Automatically draws a GPS track (a line showing the history of past added points)
Automatic centering on new GPS points
Support for multiple other tracks of co-ordinate points
Includes a comprehensive example
Simple, flat API
I have been running it on a number of embedded boards (beagleboard, Overo) for some commercial work I have been doing (hence the minimal dependencies). For those Planet GNOME readers, It is kind of like libchamplain but without the Clutter part.
Reaction to the posting of my Facebook notifier for GNOME was positive, and I made a few quick fixes to remove some crasher bugs.
The biggest source of frustration at this point is that libwebkitgtk segfaults, upon destroy, almost every time it encounters a page that requires the initialization of an NPAPI plugin. Disabling plugins using the built in BrowserSettings object does not seem to have any effect.
Is there a RoadMap or any plans for an updated WebKitGtk release before the next round of distro updates?
I have been hacking on Conduit a bit over the last few days, and thanks to Julien Lavergne we now have updated builds for Intrepid and Jaunty. Julien also packaged a trunk snapshot (and set up the infrastructure to allow easier updating of such snapshots). I recommend all users of Conduit add our PPA.

It has been a long time between posts, but I am back in New Zealand now, and vowing to get back on top of this blogging thing. I will post more in the coming weeks about my time in France with the ENAC crew, but I will start today small; by releasing some code I have been hacking on.
I wanted a small project to get back into the desktop development mindset after being in the embedded C (ARM 7 LPC2148) and OpenEmbedded (Beagleboard and Gumsix Overo) world for a while. I am also ecstatic that git was clearly the most popular DVCS in the recent survey, I really hope it provides the impetus for GNOME to move to a DVCS.
With that in mind I decided to use this small project to learn git. Firstly, github.com is the coolest thing I have ever seen. I am moving all of my projects (except Conduit) there, and using the pages and wiki features to document them as appropriate.
Facebook Notify is a small PyGtk application which monitors your Facebook profile and notifies you when it changes. Some would consider it a gross abuse of the GNOME notification area, but it keeps me out of the web browser, decreasing procrastination, thereby improving my productivity.
It notifies you when any of the following events occur;
One of your friends changes their status, profile picture, or profile details
You receive a friend request, event or group invitation
Someone writes on one of your friends walls
One of your friends is tagged in a photo
The code is a few days work, and nothing impressive. It does however contain a rather nifty deferred threaded network io system so to never block the GUI. I guess something similar could be done in C + libsoup + GTask, if one was allowed to arbitarily chain callback functions. I remeber seeing a bug and discussion about this somewhere.
The main bug is that WebKitGtk segfaults if you destroy the WebView after logging into Facebook. Not cool. Anyone know anything about this bug? Is anyone going to make an updated libwebkitgtk release soon?
So, please, fork my code. That way I have a real life example to practice merging from!
