SETI@home 3.0 Client Available -- The folks at the SETI@home distributed computing project - which takes advantage of idle systems around the world to analyze radio telescope data for possible extraterrestrial signals - have released version 3.0 of the SETI@home client for Macintosh. Version 3.0 still runs as either a screen saver or stand-alone application, and introduces new highly optimized Fast-Fourier Transform (FFT) algorithms; the performance improvements offered by the new techniques enable the SETI@home client to attempt two types of pulse detection ("pulses" and "triplets"). Version 3.0 also expands the range of Doppler shift rates examined, and tightens its Gaussian curve fitting to reduce the number of false positive reports. The client is also a little pickier about updating its 3D graph, since drawing to the screen can take longer than actually performing the computations. SETI@home 3.0 is a 450K download, and requires a PowerPC-based machine with at least 24 MB of RAM running System 7.5.5 or higher; use of the version 3.0 client will eventually be required to keep participating in the SETI@home project.

Move the Dock Quickly
You may find it convenient to move the position of the Dock when working in certain programs or with certain files. Rather than choosing a different position from the Dock preferences pane or using a submenu in the Apple menu's Dock submenu, you can move your Dock to a different screen edge merely by Shift-dragging the separator that divides the application and document sections.
