00:46.840 D-Feet graphical debugger
01:37.000 Emacs desktop environment
04:58.160 How long has D-Bus been around, and what was in place before that?
07:48.360 Why is everything D-Bus prefixed with "org."?
08:28.480 Do most OS/desktop environment/window managers interoperate well over D-Bus?
10:08.720 There is a lot of criticism against D-Bus out there. Why do you think that might be?
11:37.560 Which system services come to mind when thinking about applications, be it at the OS/DE/WM level?
12:19.720 When it comes to managing devices, how are D-Bus and udev related?
13:33.280 What is something D-Bus does that you couldn't do before? What is a really cool use of D-Bus in a modern desktop environment?
15:08.880 Can you explain briefly what clients and services can do with properties?
17:49.920 Is there such a thing as a D-Bus reflection browser, maybe Emacs-based, that lets you discover all the behavior different D-Bus app participants provide?
18:17.760 Next question, D-Bus seems great for extensibility, but then Emacs has no such mechanism and is fantastically more extensible. Why do you think this is so?
19:25.200 Do you have any other cool D-Bus ideas?
19:54.640 Are there buses besides system and session? Is there anything more to a bus besides a way to group objects?
22:52.280 What do you use it for?
25:12.480 It looks like dBus is mostly useful for Emacs to do IPC -- IIUC, this is how synctex works when working with LaTeX docs. How does it compare with other ways of doing IPC, for example, communicating over a socket with MPD?
