In Actor Prolog a resident is a special mechanism that helps processes to inspect state of other processes. A resident observes the state of a specified (target) process and if the state of the process changes (for instance, after message handling) it proves a specified predicate of the process. ... Work of the resident. ... Any change of the list of target processes or arguments of resident function results in activation of the resident and repeated collection of information in the target worlds. ...

... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...

... The retrieval method should be insulated from the user interface so that changes to one system do not force changes to the other. ... In 1993 the Hubble Data Archive group reviewed the original design of the Space Telescope Data Archive and Distribution System (STDADS) for retrieving data. The design called for any user interested in retrieving data to have an account on the operational archive system, and to use a command line syntax to retrieve data. ...
