Agave UI Experiments

So I've found myself hacking on agave a bit more lately, and I thought I'd experiment a little bit with some different UI ideas. Any thoughts and comments are welcome, of course.

Keep in mind that this is just at an experimental stage at the moment, so I may just throw it away if I decide that it doesn't work well. I do think it gives a better sense of how the colors are related, though.

In any case, it's been fun playing around a little bit with cairomm for once. In the end though, I'd probably want to implement this using some sort of canvas library, but I haven't done enough research on the options that are currently available.

Kid, you better change your feathers cause you'll never fly with those things

In theory, I'll be a father in a week and a half. It's a little bit crazy to think about. It's definitely feeling a lot more imminent lately. Joanne is very pregnant and ready to be small again, but doing really well. We've pretty much decided on a name, and have sort of entered a state of waiting.

Since it may be a while before we get to a nice restaurant, we went out for a meal at Vincent in downtown Minneapolis for Valentines day. I don't think I've ever enjoyed food as much in my life. It was absolutely phenomenal. I didn't even regret the small fortune we paid for the meal.

I just pushed out a new minor release of Agave and I've also recently added support for enabling and disabling breakpoints in Nemiver.

GDB slowness

Since I've been hacking on the Nemiver debugger, I've been doing a lot of faux-debugging (i.e. start up debugger, step through a few lines, shut down). One thing I noticed very regularly was that there were times when I'd step into a function (usually a function defined in an external library), and gdb would grind away for several tens of seconds at 100% cpu before it finally arrived at the next instruction. Apparently this generally only happens on Debian-based distributions due to the fact that debugging symbols for ld.so are not shipped by default. Installing libc6-dbg solves this problem since this package also includes the symbols for ld.so. But it would be nice if debian-based distributions (in my case, Ubuntu) would automatically install debugging symbols for ld.so as a dependency of gdb, since without these symbols gdb becomes nearly unusable. So if you've been frustrated with a slow gdb on Debian or Ubuntu, do yourself a favor and install libc6-dbg.

Happy New Year

Happy new year to everybody. I had a nice relaxing week with family and also got to stand up for a friend's wedding. It was a long needed break and the first vacation that I've had in a while where I actually felt recharged afterward. (My college engineering prof would say that's the sign of a bad vacation, but oh well...)

So, finally back to some GNOME-related hacking. Here's my belated Holiday gift to all of you brave enough to test-drive nemiver:

I've implemented a list of source files that are extracted from the executable that is being debugged. So you no longer have to hunt around in the file system to open a source file and set a breakpoint, you can now choose from a list of valid source files.

There's actually quite a few new things happening in Nemiver since the holiday break. Dodji added a basic text search, there have been several bugs fixed, and some significant performance improvements. Note that if you want to try out the new stuff in nemiver, you'll also need gtksourceviewmm from svn.

Glad to see the GNOME subversion transition went smoothly. Like Steve, I've been thinking about playing around with git-svn since I've been fairly impressed with git. I'd be interested in hearing other people's experiences with git-svn as well.
