The venerable GtkSourceView project provides a GtkWidget for various code languages. It has a number of features including the most basic, showing a line number next to your line of text. It turns out that takes a lot more effort than you might think, particularly when you want to do it at 240hz with kinetic … Continue reading Faster Numbers
To celebrate every new GNOME release I try to do a little bit of work that would be intrusive to land at the end of the cycle. The 46 cycle is no different and this time I’m making our terminals faster. The terminal is surely the most used desktop app for developers and things have … Continue reading VTE performance improvements
I obsess over battery life. So having a working Sysprof in Fedora 39 with actually useful frame-pointers has been lovely. I heard it asked at an All Systems Go talk if having frame-pointers enabled has gained any large performance improvements and that probably deserves addressing. The answer to that is quite simply yes. Sometimes it’s … Continue reading What have frame-pointers given us anyway
One thing we’ve wanted for a while in Sysprof is the ability to look at what the process scheduler is doing. It can be handy to see what processes where switched and how they may be dependent on one-another. Previously, I’d fire up kernelshark for that as it’s a pretty invaluable tool. But having scheduler … Continue reading Visualizing Scheduler Details
I like to keep myself honest by using slower computers regularly to do my job. When things become obnoxious, it reminds me to take a closer look at what’s going on. Today, I did some more profiling of 45.beta with a not-too-old-but-still-a-bit-old laptop. It’s the first laptop I received at Red Hat in 2015. X1 … Continue reading Profiling with medium-aged hardware
The problem we encountered in my last writing was that gnome-clocks was taking about 300 milliseconds to complete a basic search query. I guess the idea is that if you type “paris” into GNOME Shell you’ll get the time in either Paris, France or one of the Paris’ in the United States. I guess 300 … Continue reading Writing Fast Search
One of the things I’ve done this cycle leading up to GNOME 45 is some rework on how we process *.syscap files. In particular, I wanted to really push the GListModel interface in GTK 4. That is a tall order at first sight because Sysprof capture files easily have hundreds of thousands of data frames. … Continue reading GListModel as a file format interface
I’m the author/maintainer of Sysprof. I took over maintainership from Søren Sandmann Pedersen years ago so we could integrate it with GNOME Builder. In the process we really expanded it’s use cases beyond just being a sampling profiler. It is a system-wide profiler that makes it very easy to see what is going on and … Continue reading Frame pointers and other practical near-term solutions
After about 5 months of keeping myself very busy, GNOME Builder 43 is out! This is the truly the largest release of Builder yet, with nearly every aspect of the application improved. It’s pretty neat to see all this come together after having spent the past couple years doing a lot more things outside of … Continue reading GNOME Builder 43.0
Previously Part IV, Part III, Part II, and Part I. Still working through medicine changes which have wreaked havoc on my sleep, but starting to settle in a bit more. Template-GLib Small changes here and there for template-glib to cover more cases for us in our keybindings effort. Improved type comparisons, fixed some embarrassing bugs, … Continue reading Builder GTK 4 Porting, Part V
