Together with my colleague Stefan Lengfeld.
Tracing is a capable mechanism for deep system analysis and profiling with a minimal overhead. By recording defined system events, in Linux but also Android, tracing can be used to analyze concurrency or latency issues, for example. Android’s systrace tool made it easy to analyze and correlate traces and events due to a graphical UI, in order to help developers identify performance bottlenecks. The successor to this advanced and convenient tool is called Perfetto. It’s available for pure Linux too, and part of Yocto (meta-oe) since Langdale now. In the talk, we’ll have a look into
- using Perfetto with Android and Yocto,
- adding trace events to your applications,
- recording traces and
- analyzing system and application traces with the graphical GUI.
This will allow you to take full advantage of the Perfetto trace viewer UI for analyzing memory usage, CPU scheduling, latency and more.

Using KAS makes handling Yocto Projects easy. By shipping its own container with all needed dependencies, building sophisticated CI pipelines becomes pretty easy - in theory, or when using Gitlab.
But using GitHub as a code hosting platform with self-managed Action runners on AWS comes with a set of unexpected challenges.
Anna-Lena will talk about her quest through GitHub Actions, the Cloud and how to tame them.
The talk aims to point the audience to the obstacles when building CI pipelines for the Yocto Project with KAS, GitHub Actions, and custom action runners on AWS and strategies to handle them.

While I’m a regular visitor of the Embedded World Exhibition, this year was different. I had not only a more business-focused visit with lots of meetings with old and new partners and customers, but I also had the chance to serve rather spontaneously as a speaker, or better “Table Captain,” at the second edition of Embedded World’s women networking event #women4ew. Thus, I want to recap both parts separately and make a reference to what changed in contrast to my experiences outlined in the recently published post on International Women’s Day.

Raspberry Pi für die professionelle Produktentwicklung - Eine gute Idee?

Maschinen und Geräte durch Vernetzung und Software aufzuwerten ist ein Kerngedanke des IoT. So werden die resultierenden Projekte häufig aus der Fachdomäne mit dem Wunsch nach schnellen und einfachen Erfolgen gestartet. Die Idee liegt dann nahe den beliebten Raspberry Pi als Basis zu nutzen. Das Gerät ist ja bekannt, fast alles wurde schon einmal von irgendwem gemacht und ins Netz gestellt. Klingt fast zu schön, um wahr zu sein - ist es auch aus professioneller Sicht. Die Gründe hierfür und welche Faktoren bei der Entscheidung für eine Hard- und Software-Plattform als Basis für ein IoT Produkt berücksichtigen werden sollten, sind Inhalt des Vortrags.
