The only box that is safe is the one unplugged hdd removed and
destroyed and rest of system locked in a closet.

“Naja”, denkt man sich dann, während sich ein zartes Gefühl des Unbehagens einschleicht, “irgendwie hat der Kerl Recht.” Doch in der Zukunft der Quantencomputer kann man sich wohl noch nicht einmal auf diese so einleuchtende Weisheit verlassen, wie einer der Nachfolgeposter feststellt:

Actually, no. :) Some clever guys at UIUC managed to get a quantum CPU
that wasn’t powered on to do some calculations *anyhow*:

Now, if the program run while it’s turned off has an exploitable bug in it…..

Ein genetisch verändertes Schwein, das im Dunkeln grün leuchtet, hat in China nun selbst fluoreszierende Ferkel zur Welt gebracht.

Als ich das gelesen hatte, wusste ich nicht, ob ich lachen oder weinen soll. Betrachtet man den ganzen Artikel, wird einem der wissenschaftliche Nutzen (unabhängig von einer ethischen Bewertung) schon klar, aber irgendwie hat er bei mir ein komisches Gefühl verursacht…

Dreams Actually Virtual Reality Threat Simulation?

Time Slows Down writes
“Psychology Today has an interesting story on a new theory of why we dream. Finnish psychologist Antti Revonsuo believes that dreams are a sort of nighttime theater in which our brains screen realistic scenarios simulating emergency situations and providing an arena for safe training. ‘The primary function of negative dreams is rehearsal for similar real events, so that threat recognition and avoidance happens faster and more automatically in comparable real situations,’ he says. We have 300 to 1,000 threat dreams per year — one to four per night and just under half are aggressive encounters: physical aggression such as fistfights, and nonphysical aggression such as verbal arguments. Faced with actual life-or-death situations — traffic accidents, terrorist attacks, street assaults — people report entering a mode of calm, rapid response, reacting automatically, almost without thinking. Afterward, they often say the episode felt unreal, as if it were all a dream. ‘Dreaming is a sensitive system that tries to pay much attention to the threatening cues in our environment,’ Revonsuo says. ‘Their function is to protect and prepare us.’”
