For those using public transport we will offer a pickup service meeting the trains scheduled to arrive in Schaffhausen at 13:13 and returning in good time to catch trains leaving after 20:45. If you would like to take advantage of this offer, please indicate this when registering.

More details can be found here.

1st Swiss Ada Event (2017)

At the 2017 general assembly it was decided that we would organize a networking event for Ada users in Switzerland where people could present aspects of their projects. The first event took place on 21 September 2017 at the HSR Rapperswil. We had six very interesting presentations of about 30 min each, followed by an Ápero, which was kindly sponsored by Paranor. 18 people attended the event. The detailed program, presentations, and a link to our sponsor's website can be found below.

2nd Swiss Ada Event (2025)

The 2nd Swiss Ada Event will take place at the Sternwarte in Schaffhausen. The invitation with more details and a provisional schedule can be downloaded below.

Invitation and Schedule

Ada is an expressive and robust language in which the default for every programming construct is inherently safe. It was designed to allow programs to be engineered rather than crafted and that is why Ada is chosen for applications where failure would result in catastrophic losses in terms of human life, economic damage, or a major breach of security.

Learning Ada

A brief introduction to Ada using small examples to explain the basics.

Ada Programming is a comprehensive 600-page Wikibooks project that covers the Ada 2005, 2012, and 2022 standards.

AdaCore University is a dedicated e-learning center to teach the Ada language and the use of related technologies.

Language Documentation

The official ISO/IEC 8652:2023(E) standard and previous versions can be found here.
