About this app

Conference program for 38C3: Illegal instructions

The 38th Chaos Communication Congress (38C3) takes place in Hamburg on 27–30 Dec 2024, and is the 2024 edition of the annual four-day conference on technology, society and utopia organized by the Chaos Computer Club (CCC) and volunteers.

Congress offers lectures and workshops and various events on a multitude of topics including (but not limited to) information technology and generally a critical-creative attitude towards technology and the discussion about the effects of technological advances on society.

Starting in 1984, Congress has been organized by the community and appreciates all kinds of participation. You are encouraged to contribute by volunteering, setting up and hosting hands-on and self-organized events with the other components of your assembly or presenting your own projects to fellow hackers.

I'd prefer a single dynamic list of talks sorted by starting time and containing start time, end time, language, topic, room, and title. There should be possible to filter the list at least by topics, languages, and keywords in title/description. Then, the existing list of favourited talks should facilitate dealing with collisions. There is no need to worry about collisions before marking all favorite talks, because only then it is only possible to choose the most interesting talk.

Thank you for sharing your ideas! Search and filter functionality is definitely to come. If a single column view will be there - not sure. Conflict assistance is valuable as well. A lot of work for a single dev. You will need to be patient.

Slow + there could be also a better view of several rooms in parallel, rather than sliding left-right through 30+ rooms Anyways, as there is no competition for this product, you don't have much choice :) But big thanks for the work put in, I appreciate it greatly

Thank you for your feedback. The latest version 1.43.1 of the app has become faster. Please try it out.

Works! Two previous UX issues are mostly resolved: 1. Swiping through the rooms (left and right) is still a bit sensitive, but much improved, at least on my phone. 2. Returning to the schedule view from anywhere, there is still a small delay with no feedback, but it is short enough to ignore now.
