Hackergotchi

Thanks to everyone who made me hackergotchis but I would take either of the following made by Sean Wilson, though I would prefer the later as i really like to show off my "GObject" t-shirt :)

GUPnP stuff

Have been polishing different stuff in Universal Control Point and Network Light. Also I found some potential segfaults in GUPnP and the patches have been sent and comitted already. Now i am mostly waiting for Lapo to come-up with replacements for icons used by Universal Control Point. Here is a screenshot:

Can anyone make a hackergotchie for me from this image:

git-svn quirks

Although git is a little more than perfect now a days (git >= 1.5), git-svn however has a few quirks. Lately I got into a few frustrating problems and it turned out to be caused by how git-svn bridges the two very different worlds. What happens is that when you `git-svn rebase` (which is implicitly implied in `git-svn dcommit`), git-svn modifies the commit messages to contain an id, a git-svn-id to be precise using which it track down stuff like which latest commits haven't been committed to upstream svn repo etc. To cut the story short, here are is my advice for people who want to use git-svn on regular bases and branch (which they should):

  1. To make life simple, only have one branch sync with upstream svn repo (master branch is the most obvious choice).
  2. `git-rebase master` your branches each time after a `git-svn rebase` happens (implicitly or explicitly).
  3. Don't ever try to merge a branch once you have done that already and did a `git-svn dcommit` after you first merged it, unless you have followed point#2 above.

GUPnP Tools

Thanks to Lapo Calamandrei, now i have quite perfect images for the network light and it looks much better than that of Intel, IMO:

While Lapo was busy making the icons, I implemented the UI for the network light and also made the universal control point use icon from the device, if available to represent it in the device treeview. If things keep going on this pace, expect a 0.2 release of gupnp-tools anytime soon.

Whining

I am no expert on GPG and SSH keys and MTAs but should that mean that I should be denied write-access to projects hosted on freedesktop.org? For me that is precisely what it meant. Another sin of mine is that I have already used popular web-based email clients, first yahoo and then gmail. So the punishment i get for all these sins is the inability to get my SSH keys uploaded to freedesktop. I first tried the web interface of both gmail and yahoo to send the GPG-signed payload but both did some formating and that screwed the message. Then i tried to use thunderbird and exim4 using gmail's SMTP server, then my office exchange server (both with thunderbird and MS Outlook) but none of them worked. If it was the matter of my project, I would have decided to host it somewhere where they have something as basic as a webpage to upload the SSH key, working but unfortunately the projects i need to work on (e.g gstreamer) have been hosted on f.d.o for years now and why would anyone even consider moving to some other service for a small contributer like me.

Implementing UPnP Services just got easier

So jorn has commited my patch that implements the magic of autoconnecting action and state-variable query signals to GUPnPService. I am too lazy to write all about it so I'll just copy&paste the doc-comment:


/**
 * gupnp_service_signals_autoconnect
 * @service: A #GUPnPService
 * @user_data: the data to pass to each of the callbacks
 * @error: return location for a GError, or NULL
 *
 * A convenience function that attempts to connect all
 * possible "action-invoked" and "query-variable" signals to
 * appropriate callbacks for the service @service. It uses
 * service introspection and GModule's introspective
 * features. It is very simillar to
 * glade_xml_signal_autoconnect except that it attempts to
 * guess the names of the signal handlers on its own.
 *
 * For this function to do its magic, the application must
 * name the callback functions for "action-invoked" signals
 * by striping the CamelCase off the action names and either
 * prepend "on_" or append "_cb" to them. Same goes for
 * "query-variable" signals, except that "query_" should be
 * prepended to the variable name. For example, callback
 * function for "GetSystemUpdateID" action should be either
 * named as "get_system_update_id_cb" or
 * "on_get_system_update_id" and callback function for the
 * query of "SystemUpdateID" state variable should be named
 * "query_system_update_id_cb" or
 * "on_query_system_update_id".
 *
 * Note that this function will not work correctly if
 * GModule is not supported on the platform or introspection
 * is not available for service @service.
 *
 * WARNING: This function can not and therefore does not
 * guarantee that the resulting signal connections will be
 * correct as it depends heavily on a particular naming
 * schemes described above.

GUPnP Network Light

Thanks to all the people who made and sent icons since this morning. I think I'll use the modification from Markus Berg though but I need to sort out the legal problems (since the original icon is under cc-by-sa) first.

GUPnP Network Light

Jorn has designed such an easy API for GUPnP that I've already implemented the UPnP part of the network light. Now I'll turn towards the GUI which is quite simple now that I've these images:

The first one I borrowed from the Tango project and it's obviously made by some professional but the second one is a modification on my own using Gimp. I'll still be thankful to anyone who can make me a nicer version of the second image. Note that I've removed the shadow from the second one and I did that because the shadow becomes quite dark when i alpha-composite the two images with alpha set to max.

Oops

Didn't realize until yesterday that I had screwed-up the treeview column headers while fixing the device treeview, so had to make a quite minor release.

Network Light

I'll be mostly finished with UPnP part of the Network Light sooner than later. For the GUI part, I desperately need an image of a light bulb, actually two images of the same bulb in two different states (on and off). Any graphics artist out there who would want to contribute to this project, please contact me at zeenix @ gmail.

GUPnP Tools now under GUPnP SVN

Don't ask why would any sane person move from git to svn and just accept the fact that GUPnP Tools is now under the GUPnP SVN. I'll still mostly be using git on my side using git-svn though and i strongly suggest others to do the same since it's still much better than using SVN directly.

gupnp-tools 0.1.1 released

Minor release.

- BUGFIX: Pack the text and pixbuf in the same column of device treeview.
- Require libglade 2.6.0 rather than 2.6.1.
- Print a warning when introspection creation fails.
- Some more english fixes with the help of Robert McQueen.

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.
