... We describe a simple method to annotate shell scripts and have a preprocessor extract a set of variables, present them to the user in a GUI (using Tcl/Tk) with context sensitive help, and run the script. ... When individual applications are (tightly) integrated into the scripting language, this offers very powerful scripts, fully graphical user interfaces and a result sometimes indistinguishable from applications. ... Here is an example header from a C-shell script with which Figure 1 was made. ...

Peltier on: set temperature of -85°C produces T = 8°C camera has a 50mm silent fan. ...

... Instead the algorithm resamples the image to give each image pixel equal area within a mod-8 tile. For each mod-8 tile in the mod-8 map, the pixel x-boundaries are determined such that within each row of pixels the counts/unit pixel area is the same for each pixel, as illustrated in the left hand panel of Figure 1 . ... This is then taken as the spatial layout of pixel y-boundaries in the same mod-8 tile in the science image, which is then resampled to a grid of evenly spaced rows. ...

... Artist?s conception of the collision of Comet Shoemaker-Levy 9 with Jupiter, as seen from the Galileo spacecraft. At the time of the first impact, the comet fragments will be much farther apart than shown in this illustration. ... One orbit, computer May 18, 1993 by Syuichi Nakano, showed that the comet passed close to Jupiter in July 1992, and would pass within 45,000 kilometers of the center of Jupiter in July, 1994. ... The fragments of Shoemaker-Levy 9 move around Jupiter. ...

... Although designed for an Earth to Mars trip, it appears to pounding past Jupiter in this artistтАЩs impression. ... Thermonuclear fusion device is a polite way of saying nuclear bomb. ... The obvious way to avoid this pollution was to use ordinary rockets to launch the craft into space so that the nuclear bomb powerplant would only be activated far from Earth. A scheme for a smaller three person Orion carried into space on a couple of Saturn 5 boosters and assembled in Earth orbit was studied. ...
