10/5, Derby - A Photog friend photo’d one “of several” Lark Sparrows yesterday 10/5 at Derby Greenway’s O’Sullivan Is. Go S on Caroline St to lot at end. Along path around main pond. Tom M and I are searching; no luck yet. But very birdy with lots of warblers including 2 Tenn. Frank Mantlik Stratford Sent from my iPhone

Visited Greenwich Tod's Point Osprey nest on the 8th, and saw feeding and exercising. On the 9th, it rained heavily during my visit. The chicks alternately exercised their wings facing into the winds/rain. This simulates the parents' methods of takeoff. I could not photograph due to the heavy rains. As soon as the rain passed, they stopped exercises.

They are designed to do weird ratio frequency conversions so 10 to 12 or 10 to 16 are trivial for them. The Clockblock board was one way to get it all put together.

An AT will be lower in frequency (by many 10’s of ppm) once it warms up. An SC will be higher in frequency (again by 10’s of ppm) once it warms up. Yes, there are a variety of other cuts it could be.

I mean, the application uses 10% of cpu without any media active. Also, pjsua without any params uses less than 1% cpu after start-up, but 10% after the first call. Is it something you could improve in the future? Or is it the design, or is it not up to pjproject but to other code pjrpoject uses? Is it on a Mac only?
