Well, New South Wales, at least. It doesn't appear to be an outright ban, but owners must carry a permit. I'm just not going to wring my hands or get my shorts in a knot over this. An outright ban is a knee-jerk reaction, something governments are typically very good at. The responsible owners aren't the ones targeting aircraft. And like handgun restrictions, it won't stop the nut jobs. Here is an opportunity for an entrepreneur to make a fortune selling laser safety glasses to pilots, airlines, and the military. They've been in use in the laboratory for decades, it's time to make them standard-issue in the cockpit. Better yet, narrow-band blocking window material.

Kudos to Ken -- he's a computing maniac, and I noticed he completed over 1 million work units last weekend for seti@home. I'm sure he's one in the top list of individuals in the world. If anyone wants to "donate" spare cpu cycles to the cause, we have a small group called "Utah Astronomers" that you can join if you are already running seti@home: http://setiathome.berkeley.edu/team_display.php?teamid=32210 If not, you can download it here (it's easy!): http://setiathome.berkeley.edu/ At the very least, it's a pretty screen saver! /R ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!

Thanks Rich. It helps when you have several high end computers at your disposal. I'm currently ranked 2998 in the world and 809 in the United States. I also surpassed 1 million recently in PrimeGrid too. Now for the next million, September 13, 2008 at my current rate. :-) Ken -----Original Message----- From: utah-astronomy-bounces+killerken=killerken.com@mailman.xmission.com [mailto:utah-astronomy-bounces+killerken=killerken.com@mailman.xmission.com] On Behalf Of Richard Tenney Sent: Friday, April 25, 2008 5:59 PM To: Utah Astronomy; UVAA Subject: [Utah-astronomy] kudos to "Killer Ken" Warner Kudos to Ken -- he's a computing maniac, and I noticed he completed over 1 million work units last weekend for seti@home.

Not to take anything away from Ken's or other's dedication, but seti@homehas been off my radar for a few years, since I heard they were sending out old, already processed data as "make work" due to too many volunteers and not enough fresh raw data. Is this still the case? Any probable hits yet? On Fri, Apr 25, 2008 at 6:19 PM, Ken Warner <killerken@killerken.com> wrote:

Chuck, SETI@home continues to process fresh data. Each data block (107 seconds of data which can take hours to process) is sent out to 3 computers, processed and collected after it's processed. This helps eliminate computer errors and people just trying to cheat the system just to gain credit. SETI@home will continue with new data from Arecibo until 2011 when Arecibo may be decommissioned unless there are enough funds to keep it running. I also run this to validate the stability of my machines. If I start getting computational errors that means my machines and may have parts going bad or it's overheating. For the last 2 years a new version has been running that is more than twice as sensitive as the original version. I'm sure data that was of interest was probably sent out again for reanalysis, but that doesn't mean it was done just too waste CPU cycles. Unfortunately there have been no detected signals from Extra-Terrestrial life, but many unexplained signal spikes have been detected. In any case, it's a fun way to make your computer useful with otherwise wasted CPU time.

Ken, there actually was a period years ago when there was no fresh data available for a while, and duplicate packets were sent out. Some people got rather upset and opted-out; I remember reading about it. I may try looking this up as time permits. It wasn't done to "waste" anything, I think the organizers just wanted to keep people from getting frustrated if nothing was available for them to work on.

OK, here is what I was referring to, Ken. Duplicate "make work" was in fact sent out: http://www.skyandtelescope.com/news/3309236.html?page=1&c=y A New Step for SETI@home June 29, 2004 | A half million amateur hunters for alien civilizations are currently running the SETI@home software — which uses your computer's idle time to sift through cosmic noise from the Arecibo radio telescope for faint, artificial signals among the stars. Launched five years ago, SETI@home is now broadening its scope to become a platform for other "distributed computing" projects, such as those that use volunteers' computers to crunch data in molecular biology, climate modeling, and mathematics. The new software is named BOINC, the Berkeley Open Infrastructure for Network Computing. It will give SETI@home itself the flexibility to run additional searches using other radio telescopes and analysis strategies. Current SETI@home users will eventually need to switch to BOINC. The change will also resolve an embarrassment that has dogged SETI@home for all its life: *the project has attracted so many volunteers that most of them are given needless duplicate make-work. *BOINC will steer excess volunteers toward other projects instead. For more about this and all other SETI projects under way worldwide, see "SETI Searches Today" in SkyandTelescope.com's extensive SETI section.
