issue 96

issue 96

It’s the issue #96, and I can’t believe it’s already the 13th issue since the hard reset of the newsletter end of January. One more time this week, there are many interesting articles and I hope the ones I selected for you will help you in your job. Or, maybe, they will just open interesting discussions with your colleagues and friends. It’s already a success for the newsletter from my point of view!

Thank you to GreatScott! for the header’s picture.

Happy reading!
