April marked the return of the Embedded Open-Source Summit, this year in Seattle. I was lucky enough to be able to attend and split my time between the Memfault booth in the exposition hall and many of the captivating presentations. Since the videos have just been published on the the Linux Foundation’s YouTube account, we thought it would be a good time to highlight some of the talks and give you a quick summary which will, hopefully, inspire you to go watch them!

We cover the talks I was able to see in person, as well as some talks seen by my colleagues since they were posted. Obviously this is just our little biased selection, we have not been able to see everything, let us know in the comments what we missed!

Drew Moseley, from Toradex and ex-Mender engineer, did some great research to compare different strategies to update Linux systems. He starts with a little explanation of what delta updates can look like for an A/B system: he covers SWUpdate with ZChunks, Rauc, and Mender proprietary delta-update. Of course, he also includes Toradex and starts with a little refresher of how it works differently using libostree (a git like approach to your entire filesystem).

Then he devised a few “update scenarios”, including one very small change in a configuration file, installing a big package, removing a big package. The choice of scenarios seemed very relevant to me and I was glad to see someone take the time to “run the numbers” and compare the number of bytes downloaded for each scenario and each solution.
