Évènements
En tant que fervents partisans et contributeurs actifs de la communauté Open Source, nous participons à plusieurs réunions et conférences. Chaque consultant participe à un minimum de deux conférences internationales chaque année. Nous organisons même notre propre événement que nous ouvrons à tous ceux qui souhaitent se joindre à nous.
Dès que nous en avons le temps, nous rédigeons des retours d'expériences sur les événements et des articles détaillés sur les technologies présentées. Cela inclut les nouveaux produits en cours d’introduction et de nouvelles fonctionnalités introduites dans les versions futures.
