The N900 address book can merge multiple contacts into a single entity: if you have a friend that has a phone number, an email address, a Jabber user name, a MSN one and so on, then you can merge all of the different entities into a single meta-contact. Locally stored details and an IM user [...]

Sometimes the creation of the contact chooser used on the N900 can be slow so, using callgrind and kcachegrind, I tried to understand what is the source of the slowness. This lead me to find some unexpected, and apparently undocumented, differences between upstream GTK and the Maemo version. The Maemo 5 contact chooser The widget [...]

During the Christmas holidays I managed to find some time to write a couple of small programs related to the address book on the N900; they are nothing too fancy (no UI, no proper packaging, not the best code quality, etc.) as I wrote them for my personal use, but I still think it could [...]

It looks like Santa Claus arrived early for the Collabora employees N900 pyramid, and sadly some of them didn’t arrive yet

In the last months the traffic on the #telepathy IRC channel on Freenode has been constantly growing, reaching the point where communication among developers is difficult and, at the same time, some new Empathy users are scared and don’t talk on the channel. This is why we just created a new #empathy channel on GIMPNet [...]

After the Maemo Summit the details on the address book application and framework in Maemo 5 are finally completely public so I can openly talk about what I worked on during the past year and, even better, I actually have a smartphone that runs this software! (Thanks to Nokia that gave out 300 N900s, but [...]

Ross, your examples are not as bad as something I found in some code I had to fix recently: GList *list = e_vcard_get_attributes (evcard); for (list = g_list_first (list); list != NULL; list = g_list_next (list)) { /* Do something */ } for (list = g_list_first (list); list != NULL; list = g_list_next (list)) { [...]

In the last weeks I have been asked several times to modify some components I’m working on to add the ability to split a full name in its components (first name, family name, etc.). It looks like most people have great expectations about this working correctly but they get annoyed when it fails, and you [...]

When I joined Collabora last year I started to work on porting WebKit GTK to a device produced by iRex technologies based on the GNOME mobile stack and with an electonic paper display. My task was to make WebKit usable for the browser that they want to ship with the next version (with Wi-Fi connectivity) [...]

In the Telepathy framework there is a mechanism, called tubes, for arbitrary data transfer with your IM contacts so you can play games, do collaborative editing, etc. Until now telepathy-gabble (the component that does XMPP) supported only in-band bytestreams, or IBB for short: all the data is sent inside the XMPP stream encoded in base64.
