April 2022 Newsletter

[OW2 Newsletter - April 2022 - From the OW2 Management Office]

Dear OW2 Members, dear All,

This is my first newsletter as CEO of OW2: I would first thank former CEO Cédric Thomas for 15 years leading OW2, and our President, Jean Parpaillon, so helpful during the transition. You made OW2 what it is now, and built the team that will bring it further, I am so proud to be part of.

I am not the only newbie on board: as of April 4, OW2 has a new SysAdmin, Alban Espié-Guillon, so we are fully staffed to accomplish our duties. Welcome Alban, and warm thanks to our CTO, Antoine Mottier, for the interim!

So, a new era opens up: no revolution, OW2 remains dedicated to promoting professional open source and taking care of its members and their projects. But we will keep innovating step by step, as our mission requires, as we always did, considering tradition part of the ultimate avant-garde.

Among breaking news, OW2 just released a paperback edition of the Open Source Good Governance Handbook, elaborated in partnership with OSPO.zone (also available there for free download): it makes us a technical book editor, with a set of ISBNs available for further publications. Anyone with a good idea of technical open source book, like some project user manual? Let us know!

Also, a quick update about our community: PrestaShop, the famous open source e-commerce solution, joins OW2 as a new member and new project! And we are happy to announce another new project in our code base: Mercator, an open source Information System Mapping solution and webapp.

Last, in June, we will run the OW2con'22 conference: virtual again this year (June 8-9), but followed by a real-life event in Paris, to celebrate our 15-year anniversary, June 29-30. Save the date, you are welcome, and we are impatient to meet our community again after two years of pandemic! Stay tuned at ow2con.org.

Thanking you for your on-going support, and looking forward to meeting you,

My thanks to each and everyone of you for your on-going support during the past 15 years. Keep OW2 thriving!

Pierre-Yves Gibello
