China recorded the most sleep, with more than nine hours of sleep, according to a 2011 OECD report. Could that have something to do with the highly-accepted practice of public sleeping? Japan, on the other hand, gets the least, with seven hours and 14 minutes of shut-eye each weekday. Time spent sleeping has been steadily declining since the 1970s, according to the 2010 time use report -- and Internet use has been on the up and up.
Null Byte Injection. Null Byte Injection. Null Byte Injection is an active exploitation technique used to bypass sanity checking filters in web infrastructure by adding URL-encoded null byte characters (i.e. %00, or 0x00 in hex) to the user-supplied data.
IsNull returns True if expression is Null; otherwise, IsNull returns False. If expression consists of more than one variable, Null in any constituent variable causes True to be returned for the entire expression. The Null value indicates that the Variant contains no valid data. Null is not the same as Empty, which indicates that a variable has not yet been initialized. It is also not the same as a zero-length string (), which is sometimes referred to as a null string. Important Use the IsNull function to determine whether an expression contains a Null value. Expressions that you might expect to evaluate to True under some circumstances, such as If Var = Null and If Var <> Null, are always False. This is because any expression containing a Null is itself Null and, therefore, False.
