Merci à Riduidel pour le lien.

Remarque :

• Le concept de cache ici pose problème puisque des méthodes qui transforment (à base de verbes) retournent en réalité quelque chose.
• Les méthodes avec des boolean ont des verbes, c'est une exception à la Yegorification du code.

// Usage :
object Main {
    fun regularUseCase() {
        // Given
        val christmas = LocalDate(2019, 12, 25)
        val calendar:HolidaysCalendar = HolidaysCalendarForYear(Year(2019))

        // When
        val daysOff:DateSet = calendar.daysOff()

        // Then
        println(daysOffs.contains(christmas))       // print true
    }

    fun cachedUseCase() {
        // Given
        val christmas = LocalDate(2019, 12, 25)
        val cache:Cache = HolidaysCalendarCache()

        // When
        val daysOff2:HolidaysCalendar = cache.value(Year(2019))
        val daysOff3:HolidaysCalendar = cache.value(Year(2019))

        // Then
        println(daysOff2.contains(christmas))       // print true
        println(daysOff2 === daysOff3)              // print true (same instance)

Je veux jouer à cela ce week-end ! @Chlouchloutte, tu mets ce lien de côté sur ton PC ?

Oula la !! De gros changement dans udev déjà sur Ubuntu (we don't care) mais aussi sur Debian (we don't "don't care" hein). En gros eth0 disparaît au profit d'une nouvelle convention de nommage fixe dans le temps.

Tout ceux qui développent un script udev devraient y penser (Animal, spourtoi).

Un article à troll sur l'usage des frameworks. Ce n'est pas le contenu de l'article qui m'intéresse ici mais le design du site. Je parle pour ton projet Roudoudoutte, dis-moii ce que tu penses de la GUI.
