Essen Hackathon & BSDCam 2018 trip report

Allan and Benedict met at FRA airport and then headed to the Air Rail terminal for our train to Essen where the Hackathon would happen over the weekend of Aug 10 - 12, 2018. Once there, we did not have to wait long until other early-arrivals would show up and soon we had about 10 people gathered for lunch. After buying some take-out pizzas and bringing it back to the Linuxhotel (there was a training still going on there so we could not get into our rooms yet), we sat in the sunny park and talked. More and more people arrived and soon, people started hacking on their laptops. Some people would not arrive until a few hours before midnight, but we already had a record appearance of 20 people in total.
On Saturday, we gathered everyone in one of the seminar rooms that had rooms and chairs for us. After some organizational infos, we did an introductory round and Benedict wrote down on the whiteboard what people were interested in. It was not long until groups formed to talk about SSL in base, weird ZFS scrubs that would go over 100% completion (fixed now). Other people started working on ports, fixing bugs, or wrote documentation. The day ended in a BBQ in the Linuxhotel park, which was well received by everyone.
On Sunday, after attendees packed up their luggage and stored it in the seminar room, we continued hacking until lunchtime. After a quick group picture, we headed to a local restaurant for the social event (which was not open on Saturday, otherwise we would have had it then). In the afternoon, most people departed, a good half of them were heading for BSDCam.
Commits from the hackathon (the ones from 2018)
Overall, the hackathon was well received by attendees and a lot of them liked the fact that it was close to another BSD gathering so they could nicely combine the two. Also, people thought about doing their own hackathon in the future, which is an exciting prospect. Thanks to all who attended, helped out here and there when needed. Special Thanks to Netzkommune GmbH for sponsoring the social event and the Linuxhotel for having us.
Benedict was having a regular work day on Monday after coming back from the hackathon, but flew out to Heathrow on Tuesday. Allan was in London a day earlier and arrived a couple of hours before Benedict in Cambridge. He headed for the Computer Lab even though the main event would not start until Wednesday. Most people gathered at the Maypole pub on Tuesday evening for welcomes, food and drinks.
On Wednesday, a lot of people met in the breakfast room of Churchill College where most people were staying and went to the Computer Lab, which served as the main venue for BSDCam, together. The morning was spend with introductions and collecting what most people were interested in talking. This unconference style has worked well in the past and soon we had 10 main sessions together for the rest of this and the following two days (full schedule).
Most sessions took notes, which you can find on the FreeBSD wiki.
On Thursday evening, we had a nice formal dinner at Trinity Hall.
BSDCam 2018 was a great success with a lot of fruitful discussions and planning sessions. We thank the organizers for BSDCam for making it happen.
A special mentions goes out to Robert Watson and his family. Even though he was not there, he had a good reason to miss it: they had their first child born at the beginning of the week. Congratulations and best wishes to all three of them!


###Call for Testing: ZFS Native Encryption for FreeBSD

A port of the ZoL (ZFS-on-Linux) feature that provides native crypto support for ZFS is ready for testing on FreeBSD
Most of the porting was done by sef@freebsd.org (Sean Eri
