Since publishing the last issue of LIFELINE, I received a unique letter which I am including in this issue in its entirety and without any editing. This reply is not only laid out in newsletter fashion but also includes a kaleidoscope of new and interesting discoveries. I certainly welcome any and all letters of this nature no matter how long or short!

As usual, I will present a cross-section of the new and more recent discoveries reported by all the readers who have taken the time and effort to reply.


Petrie's pentadecathlon, profound, and Prolific predecessors

The glider arrangements shown on this cover page of LIFELINE Number Ten are described in the previously mentioned letter sent in by Douglas G. Petrie of Lake Oswego, Ore. These patterns discovered by Petrie produce respectively in a varying number of generations, the pentedecathlon(!), Conway's heavyweight spaceship(l!), and Corderman's Switch Engine(!!!). Details of these reactions and other newsworthy events are described in Petrie's letter which begins on page three. Is there anything beside Gardens of Eden that can not be constructed with gliders?

Lifequote submitted by Mark Linimon of Houston, Tx: 'Life is too important a matter to be taken seriously.' . . . Oscar Wilde

gollark: Which is all you will actually be able to do if MitM-attacking.
gollark: Browsers will warn you a lot now if you're using a HTTP version of a site.
gollark: HTTPS is an excellent mitigation, especially with HSTS.
gollark: I mostly don't mind open WiFi networks because my stuff has various forms of encrypted DNS configured and MitM attacks aren't very practical now.
