I haven't had much luck finding documentation on the dbus security model. In particular, how does one prevent one application from spoofing another application's "identity". That is, if I created an application that watched for new launches and managed to guess the activity ID of the launched application, registering a DBUS service for that activity ...

The HIG mentions that we'll want a view in the Journal that allows you to launch a given Journal entry (project environment) with a different application than the one that last edited it. I'm thinking we're going to want a way to do the same without needing a close-launch cycle.

For instance, you're working with ...

Something that's been rattling around in my mind for the past week is the need to integrate removable storage into the Bitfrost and Journal systems. Obviously we don't want to automatically include anything ever plugged into the system into the backup/Journal system, but if I share a file off my USB key or USB hard-drive ...

Did a very solid day's work on Friday for the main client. 6.5 hours on-task out of 7.5 hours at the "office" (Linux Caffe), with the last .5 hours actually being some play with trying to get the PyGame applications running on my BTest2 machine while the thunderstorm was raging. Going to have to make ...

xsltproc and saxon are producing mutually unintelligible files and/or taking dozens of computer-hours of processing time to do the merge. Bit of a PITA, especially as these are the old source documents still (haven't received word back from the OpenGL board guys about using the 2.1 documentation set) so I will need to re-do anything ...

Sent off the cheque to pay for the pygta.org domain name yesterday. Would be nice to have the key information on the front page (e.g. our regular meeting time), some basic who/what/why/when/how information too would be good for the front-page. Guess I should find some time to work that up and ask Peter to update ...

Spent a few hours trying to get Fedora 7 working under vmware last night. I'm guessing the problem is simple, but on Fedora I'm just stumbling around blind to some extent. I can modprobe the pcnet32 driver, but hotplug/coldplug doesn't seem to pick up the new device. Freaky thing is that the system has an ...

As I was walking home I was considering the question of large-media "special events", such as wanting to watch a multi-GB movie off the network at school. If the class wants to record an event (school play) at high enough resolution to do a good job of editing where would the children store the gigabytes ...

One of the issues still pending in the overlay filesystem approach is how to handle persistent information for a given application in a general way. Some examples of persistent information use-cases:

Most document-editing applications include a "most recently used" list of the documents edited within them that can be selected and edited with a single ...

I think I'm to the point of wanting the overlay security mechanism and journal I've been describing on my own machine. That is, if we can implement everything it would allow me to work on my own machine (and I have rather demanding requirements from a computer) while still providing extensive protections and a number ...
