I have the pleasure to attend Akademy this year again. From my past experience, I’m really looking forward to have a good time again. Lots of hacking, meeting known and unknown faces, drinking beer and socializing ahead! I also love that it’s in a (to me) new country again, and wonder what I will see of the Czech Republic and Brno!
This year, the conference schedule is a bit different from the past years. Not only do we have the usual two days packed with interesting talks and keynotes. No - this year there will also be workshops on the third day! These are more in-depth talks which hopefully teach the audience some new skills, be it QML, mobile development, testing, or … profiling :) Your’s truly has the honor to hold a one-hour Profiling 101 workshop.
I welcome all of you to attend my presentation. My plan, currently, is to do some life demoing of how I profile and optimize code. For that purpose, I just wrote a (really slow and badly written) word count test-app. I pushed the sources to kde:scratch/mwolff/akademy-2014.git. If you plan to join my workshop, I encourage you to download the sources and take a shot at optimizing it. I tried my best to write slow code this time, to leave plenty of opportunity for optimizations :) There are many low-hanging fruits in the code. I’m confident that I’ll be able to teach you some more advanced tips and tricks on how you can improve a Qt application’s performance. We’ll see in the end who can come up with the fastest version :)
During my workshop, I’ll investigate the performance of the
wordcount app with various tools: On one hand this should teach you how to use the powerful existing opensource tools such as Linux
perf and the valgrind suite. I will also show you Intel VTune though, as it is still unparalleled in many aspects and available free-of-charge for non-commercial usage on Linux. Then, I’ll present a few of my own tools to you, such as heaptrack. If you never heard of some of these tools, go try them out before Akademy!
I’ll see what else I’ll fit in and maybe I’ll extend my
akademy-2014.git scratch repository with more examples over the next days.
Bye, hope to see you soon!
