Anyone who still had energy after the presentations on the first day could take part in the TYPO3 certification. The participants were informed about the success or failure directly after the T3DD19. The first day ended with a dinner and BBQ for all participants.

The second day's workshop highlight was "Performance profiling" with the help of Blackfire.io with Benni Mack as speaker. Here it was explained how to find "lame spots" in the code without following false trails for too long. During the talks on this day, a lot of space was given to TYPO3 documentation, where a lively exchange between the participants took place.

The WLAN and the internet uplink were a little bit buggy on all days, but in most cases it was possible to work as needed.
On the second evening, the Coding Night took place, where the developers were able to work on TYPO3 Core topics late into the night with the help of Core Team members.

On the one hand, a lot was learned there, and on the other hand, the TYPO3 team was pleased to receive numerous closed tickets after the successful Coding Night.

The Coding Night was followed by a full day of presentations on Saturday. The participants learned many tips for their daily work with TYPO3.

Social event with dinner in the garden and 90s party

The final panel of the day flowed almost seamlessly into the traditional social event, which once again tested the developers' resilience to sleep deprivation.

At this point, special thanks to the AkademieHotel, which allowed us to party until 3:30 in the morning.

The DevDays 2019 concluded on Sunday with the topic of security in web applications. Oliver Hader shed light on this difficult topic in a two-hour workshop. Using selected examples, he showed in an entertaining way that even supposedly minor "sloppiness" in the code can lead to major disasters if they are not eliminated in time.

In the series of presentations, participants were able to find out about event-based programming with the help of the PSR-14 Event Dispatcher. Benni Mack demonstrated the advantages of this over the usual method using hooks.

We were also able to pass on a lot of our knowledge

We were particularly pleased that we were able to pass on knowledge from our projects in very different areas to the community in a total of 5 talks.

Christiane Helmchen and Alexander Böhm kicked things off by sharing their experiences with complex editor authorizations in the TYPO3 backend. On Friday morning, Stefan Kosker gave an in-depth introduction to the background of search engine algorithms and showed what this means for the SEO optimization of websites.

Christian Keuerleber gave a quick run-through of our front-end testing stack with Codeception and received a lot of interested feedback. Jan-Michael Löw introduced a less technical topic. In his talk on ethics in web development, he called on developers to take their responsibility seriously and take a stand against the unethical use of their work.

On Friday, Lars Liedke then gave insights into our punkt.de hosting infrastructure around the proServer.

In case you missed the talks: All talks were recorded and will be published on YouTube in the next few days, where you can catch up on them at your leisure.

Grand finale TYPO3 DevDays with Best Paper Award

At the end, the best talks in each of the three tracks were honored. Special thanks go to all the speakers. The following talks were chosen by the participants:

After four eventful days, the participants were able to take a lot of new knowledge home with them. The punkt.de was delighted to organize this event and we are pleased with the positive feedback we received from all sides.
