Surprising side effects

Keyjacking: the surprising insecurity of client-side SSL

In theory, PKI can provide a flexible and strong way to authenticate users in distributed information systems. In practice, much is being invested in realizing this vision via client-side SSL and various client keystores. However, whether this works depends on whether what the machines do with the private keys matches what the humans think they do: whether a server operator can conclude from an...

Time perception: the surprising effects of surprising stimuli.

The effects of stimulus repetition often increase when repetitions are more common (i.e., when repeats become more predictable), consistent with the idea that repetition effects reflect expectations about the recurrence of recent items. In contrast, the present experiments found a surprising pattern in which the compressed subjective duration of repeated items was reduced, eliminated, and even ...

Side Effects

This section covers basic topics and illustrates the technical notion of a computational effect with several mathematical and programming examples. In everyday language, a “side effect” refers to the unintended or unforeseen consequences of an action. By analogy, in order to identify the side effect of a given computation, it is first necessary to isolate the “publicly stated” or “publicly expe...

Codeine effects and side effects

Curiosity about codeine can lead to copious information, so first it?s good to focus on the basics. Codeine is a prescription opioid/narcotic analgesic [2] that?s typically used to reduce coughing or to relieve mild to moderate pain by acting on the central nervous system (CNS, more on this later). That said, it?s good to be aware of potential risks associated with taking this medication. Codei...
