Noted astro-sketcher Jeremy Perez of Flagstaff, Arizona, made an observation and drawing of Comet PANSTARRS on March 19 while he was out of town visiting family in Elk City, Oklahoma. He reported, "Despite Elk City having lower altitude than Flagstaff and more moisture in the air, the comet was in great form and showing off lots of structure in its tail. I noted three brighter plumes in the main curving section of the tail. There was also a faint straighter edge along the north edge. ...

... 400mm f/2.8 Nikor lens: images the sky on the entrance slit. ... The optical system maintains image quality along the slit length so that each row of the image is a spectrum of that spatially selected region of the sky. 180mm f/2.8 Nikor lens: collimates the light from the slit. ... The auxiliary optical platform on WISPI now accomodates a short focal lens and a guiding/imaging video system that may use sub-pixel corrections to provide feedback to the tracking drive motors. ...

... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...

While Apache is for the most part a drop-in replacement for NCSA's httpd, there are a couple gotcha's to watch out for. These are mostly due to the fact that the parser for config and access control files was rewritten from scratch, so certain liberties the earlier servers took may not be available here. ... The basic mod_auth AuthGroupFile -specified group file format allows commas between user names - Apache does not. ... Apache does not implement OnDeny ; use ErrorDocument instead. ...

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. ...
