+ | Bienvenue de retour dans un nouvel épisode de Q. ET A. ! Ici, nous essayerons de répondre à vos questions sur Ubuntu. Assurez-vous d’ajouter les détails de la version de votre système d’exploitation et de votre matériel. J’essaierai d’enlever les chaînes qui vous identifieraient personnellement des questions, mais il vaut mieux ne pas inclure des choses comme des numéros de série, des UUID ou des adresses IP. Si votre question n’est pas publiée tout de suite, ce n’est que parce qu’il y en a vraiment beaucoup et j’y réponds sur la base du premier venu, premier servi. | ||
- | A while ago I applied for a position at a firm that specializes in IT security. At the interview, I was told that they prefer a candidate with a university degree. So I asked, “so you are saying that you discriminate against poor people?” Which in hindsight probably was not the thing to say, but since I have no filter, it probably needed to be said. After they tell me about their state of the art systems and brag about their PhDs working for them, they ask if I think I can get into their system. I say yes, very confidently.

A: When an item is moved to trash, like other operating systems, you can recover it from there. Delete is delete. That said, if you install “testdisk” when you set up your Ubuntu machine, it allows you to recover files.
