As most of you probably know already, GUPnP is now officially part of Maemo and therefore future internet tablets. This is a major milestone and gives a big boost to my motivation to continue my UPnP adventure. Although I try to put as much of the bits and peaces of spare time i get from my job into UPnP work and I am pretty sure the Intel (former OH ) will continue their work as well, we could certainly use more hands to accelerate the development. If you want to help, here is a short list of TODOs that you might want to have a look at and decide if you could help on any of these: Bindings : Although the more bindings we have the more worlds we can conquer but what we definitely need is bindings for most popular languages in GNOME/Maemo world, namely C#/mono, Java and Python. If you are interested in helping with this, I strongly suggest you take the g-i-r route . Also if you are only interested in C# bindings, I suggest you talk to Jerome Halton who already have a half-baked solu

Many thanks to Olivier Crête , we now have a nice small library for firing holes through firewalls using a part of UPnP IGD API. This library also provides a convenient way to do all that without having to use a gmainloop. While Olivier will most probably use it in his farsight2 , I am sure this will be useful for other projects (I did not say Ekiga :)) as well.

My last blog post managed to attract the attention of some of our beloved GNOME developers, especially the ones working on/with embedded systems. That made me realize that I am not (at least completely) on crack and decided to file a nice big bug for addition of something similar to GstMiniObject to core gobject library. Lets see what happens next. :)

I had always been hearing that GObjects are slow and it's not always a good idea to use/write them but I never saw any evidence to support that. I had this desire to write a test application to get this evidence but felt too lazy to do it in C. I realized a few days ago that I can write such an app very easily in Vala without giving up much on my laziness. :) So here is an app that I wrote last evening after returning from vacation. Here are the results on my laptop: $ ./test-perf 0.000182 seconds taken in creating 10000 structs. 0.001598 seconds taken in creating 10000 instances (compact). 0.003522 seconds taken in creating 10000 instances. 0.090455 seconds taken in creating 10000 instances (GObject). The ranking is exactly how I expected it to be but didn't expect such a big difference between them all.

What a beautiful country. The people were very nice and the food was just amazing.

After reading/watching Stuart's nice slides on Closures in the context of JavaScript, I have started to like JavaScript. Personally, I don't accept any language as a high-level scripting language if it doesn't support closures. Python is therefore straight out of my window. Although Vala isn't a scripting language, it would be nice to have such support in there as well. It already supports lambda functions with no restrictions and Jürg has concrete plans to support closures, it's more a matter of when rather than why or how. When that support is there, just try and stop me from loving Vala. :) UPDATE : Thanks to Anonymous, I now stand corrected that Python does fully support closures. Although I still don't like the fact that it restricts lambda functions to be one-liner but at least it's not straight out of the window anymore. :) UPDATE#2 : Andy Wingo informs me that python doesn't really fully support closures. He even put up a small code fragment to

Since I totally agree with last two blog entries of Havoc, I originally started to write this entry to get them to the planets I am on and he is not (yes, there are some) but then I couldn't resist adding my own thoughts. :) Regarding "embeddable" scripting languages, I came-up with the exact same conclusion 4-5 year ago. When I looked around at that time, I realized that GNU had realized that long time ago and had a nice embeddable implementation of the easiest yet powerful language, Scheme. Guile was the name of that implementation. I soon became a firm believer of "Most of the implementation in C, while the highest-level (only) logic written in Scheme/Guile". While I was acting on my belief, I couldn't help but notice that the only other person in the whole GNOME community that had similar vision was Andy Wingo. Many (if not most) had been going for Python. Some of them even took this scripting language as far as coding complete frameworks in it. As
