Up until now, talking in-depth about userspace tracing was deliberately avoided because it merits special treatment, hence this part devoted to it. We'll now look at the why of it, and we'll examine eBPF user tracing in two categories: static and dynamic.

Now that we've studied the mainstream way of developing and using eBPF programs on top of the low-level VM mechanisms, we'll look at projects taking different approaches, attempting solutions to some of the unique problems faced by embedded Linux.

In part 1 and 2 of this series, we took a condensed in-depth look at the eBPF VM. In part 3, we define the high-level components of an eBPF program, including the backend, loader, frontend and data structures.

GStreamer's logging system is an incredibly powerful ally when debugging but it can sometimes be a bit daunting to dig through the massive amount of generated logs. I often find myself writing small scripts processing gst logs when debugging.

The second part of this series takes a more in-depth look at the eBPF VM and program studied in the first part. Having this low level knowledge is not mandatory but can be a very useful foundation for the rest of the series.

In an ideal world, everyone would implicitly understand that it just makes good business sense to upstream some of the modifications made when creating your Linux powered devices. Unfortunately, this is a long way from being common knowledge.

How can we measure the comprehensiveness of a test suite? Code coverage is the standard metric used in the industry and makes intuitive sense. However, it can often present some difficulties for large scale surveys.

For the last month or so, I've been playing with a new project during my work at Collabora, and as I've already briefly talked about at XDC 2018, it's about time to talk about it to a wider audience.

For projects of any value and significance, having a comprehensive automated test suite is nowadays considered a standard software engineering practice. Why, then, don't we see more prominent FOSS projects employing this practice?

After I started working for Collabora in April, I've finally been able to put some time on maintenance and development of Geoclue again. While I've fixed quite a few issues on the backlog, there has been some significant changes as of late.
Here are the events we'll be attending in the coming weeks – come say hello!
December 10-15, Vancouver, Canada
February 1-2, Brussels, Belgium
Whether writing a line of code or shaping a longer-term strategic software development plan, we'll help you navigate the ever-evolving world of Open Source.
