Une CMDB imparfaite vaut-elle mieux que pas de CMDB
À 8 h 40, une application de prise de commandes ralentit. Le support voit des alertes contradictoires et le métier réclame un rétablissement immédiat. Personne ne sait cependant si le service dépend encore d’un ancien serveur d’authentification, quel contrat couvre le composant défaillant ni qui peut autoriser un changement. Cette scène est illustrative, mais le dilemme est courant : faut-il attendre une CMDB exacte avant de s’en servir ? La mauvaise réponse oppose perfection…

A New Benchmark for De-Aging Comes From Slowly Turning Back Cells’ Clocks
Scientists have long known how to make cells younger—at least in the sense that adult cells can be converted into pluripotent stem cells very similar to those found in embryos. While this capability has been foundational for biological research, these methods aren’t viable for anti-aging technologies, for a few reasons. “You don't want to have a pluripotent cell in your body, because it can become all types of cells,” says Oliver Brüstle, a professor…
