    1. Willkommen

- Was ist Show and Tell? - Wie funktiniert das?

    1. Was wir heute gelernt haben:
      1. Ansibug

The core component of the Ansible Debug Adapter Protocol used for debugging Ansible playbooks. - [Documentation](https://jborean93.github.io/ansibug/) - [Github Repo](https://github.com/jborean93/ansibug) - There's extensions to integrate ansibug with your IDE/Editor of choice 

 - nvim
 - Visual Studio Code

Very useful for debugging [Jinja2](https://en.wikipedia.org/wiki/Jinja_(template_engine)) templating.

      1. Regexp101.com

- used for development/debugging regexp for rspamd-Multi-Map-RegExp for fighting SPAM with good technical measures (f.e. SPF, DKIM, DMARC) - Spammer don't have working encoding either and get mojibake in the mails too - Spammer permutate subjects - very convinetend tool to check regexp right and testing - colored highlights of matches in the test - supports differen regexp flavors - Regexp/Test String are shareable with a link but no collaborative editing

      1. Kescher Email User-Self-Service

      1. Security.txt

https://securitytxt.org

Common best practice to announce a security contact.

Also have a look at: RFC 2142 MAILBOX NAMES FOR COMMON SERVICES, ROLES AND FUNCTIONS

And have security@example.org end up somewhere where a human reads it.

      1. Data stream processing

Process data in small chuncks as it comes by. But get really good performance out of it.

Use llvm profiling to hint the compiler and learn how code is getting optimized by the compiler.

https://tomorrowcorporation.com/humanresourcemachine

A game that teaches you basic assembly.


      1. Salt-Shaker refill helper/Salzstreuer Nachfüllhilfe (+OpenSCAD Source)

https://www.printables.com/model/955884-salt-shaker-refill-helpersalzstreuer-nachfullhilfe

A printable object to easily refill a salt-shaker. (Yes, it's a slightly overengineered funnel.)

Constraints based, code CAD. https://github.com/CadQuery/

      1. OpenSCAD

CGAL, code based CAD. https://openscad.org

      1. SIGBOVIK
