Google Earth's idea of what the old conical sawdust burner looks like, that's in Felton's San Lorenzo Lumber lumberyard next to Roaring Camp.  Tea, anyone?

Yesterday, I read somewhere about the upcoming conjunction of the moon, Mars, and Venus that would be visible last night.  Didn't think much of it because the last few days had been foggy along my commute, so I didn't expect to get to see this event.

Well, I left work and drove up to Skyline, and when I got to Windy Hill, I looked west, and there they were, along with a final residual sunset glow beneath them.  It was pretty awesome -- crystal clear, gorgeous setting ... unfortunately, I didn't have my real camera on me, so the shots I got from up there are from my phone.  I did call Deb, and she went out and got a nice shot of how it looked from home.

A few links about this conjunction...

Having both oak trees and pines in my yard, I see a lot of Acorn Woodpeckers (e.g., https://plus.google.com/+DougLandauer/posts/1h39mSPN8m3).  These photos are of a different kind of woodpecker.  I think it's a Nuttall's Woodpecker.  I think it's the first woodpecker I've seen in my yard (in 32 years of not very careful observation) that was not an acorn woodpecker.

Rob reaches Ushuaia.  Awesome!  Big thanks for the engaging descriptions and wonderful photos of the journey!  Looking forward to your reflections and to the Eurasian Adventure.
The wind had died down - barely - by the next day, and I gladly made my way southeast. Supposedly, the wind was supposed to be from the northwest, but no, it was from the west, like always. That meant it was a tailwind, but n...

Went to Aldo's at the Santa Cruz yacht harbor on Saturday night -- this was the night of the Santa Cruz Lighted Boat Parade.  We had great weather, and a fun time.  One boat had beautiful lit-up jellyfish things hanging from the mast, another was a huge rudolph, with awesome antlers and a big red nose at the bow.  There was a wa`a ka`ulua -- a double-hulled polynesian-style canoe, complete with hula dancers.  Saw a great blue heron just hanging out by the channel, and somebody had a quadcopter drone flying over.  They had the lighthouse lit up very nicely.  Fun time.

For later, when Bowen is a little older:  when my 9-year-old-nephew asked me "when are we going to go on a backpacking trip?", my choice was the first few miles of the High Sierra Trail in Sequoia NP ... starts around 6000 feet, and climbs only about 1000 feet in the course of 10 miles to Bearpaw High Sierra Camp.  With two or three campgrounds along the way.  All high on the side of the U-shaped, glacier-carved middle fork of the Kaweah River with amazing views of the Great Western Divide.

Ben didn't carry much on that trip.  But we took similar trips every year for the next nine or ten years  or so, and four to six years after that first one, Ben was 6 feet 4 and on his school's football and wrestling teams, and he could carry most of the stuff :-)

Scared up a turkey on my commute down OLH this morning.  She (I guess) was on a very narrow part of the road as it traverses a steep hill, so she had no place to go but on down the road. Followed her slowly for about a minute before she finally found a driveway.  Sorry 'bout the crappy phone photo.

Unrelated:  a few minutes later, on 280, I was amused when I saw a truck that said it was from a "HERB LAVENDER" company.  Seems legit.

Around two years ago, I took these shots of egrets at the rookery on the edge of the Google Mountain View campus.  This is along the short north-south stretch of Shorebird Way, east of Shoreline and south of Charleston.

That rookery came up in conversation at work this week, so I went looking for the place where I had posted these -- or thought I had.  Not finding any such posting, here we go.  Most of these are Great Egrets -- orange beaks and black feet.  The smaller Snowy Egrets have black beaks and orange feet; there are plenty of both species at this rookery, as well as other spots in and around the Google campus and nearby MTV Shoreline Park.

These pix were taken in spring; you can see some nest-building activity.

We have some friends in Boulder Creek, who just moved into a house tucked inamongst the redwoods just outside of town.  While moving in and checking the yard out, they discovered a bunch of small figurines that look a bit like old chess pieces.  Our friends collected the pieces, and now they live on a window sill as if they are a defensive force protecting the house against attack from the outside, as long as the attackers are small enough.

These little guys reminded me of one of my favorite Dougie MacLean[1] songs, "Marching Mystery"[2], which was inspired by the Lewis (Uig) Chessmen[3], some 12th-century chess pieces found near Uig, on the Isle of Lewis, in the Outer Hebrides off the northeast coast of Scotland.

(Yeah, I know some hippie-made crafts pieces probably from the 1970's aren't really comparable with 12-century artifacts, but hey, in California we find our "ancient" history where we can.)

Here's the polynesian dancers on the double-hulled voyaging canoe at the lighted boat parade.  Sorry it's so dim.

Wallowing in my past made me look around a bit ...

I was a freshman at UCLA in June 1969, and my first (non-paper-route) job started that summer, writing some test programs to verify the connection between the Sigma 7 (the first host on the ARPAnet) and its IMP.  As I recall, it was Steve Crocker who walked into the UCLA Computer Club office one day, and JQB, TG&, and I (DAL) got jobs for that summer.  We shared an office in Boelter Hall, where Jon Postel, Vint Cerf et al also worked.

Doing a few image searches today, I found this odd "how the sausage is made" photo:  Vint Cerf, Steve Crocker, and Jon Postel "talking" on a network of vegetables strung together like sausages, to connect tin can terminals.  Looks to me like that photo was made some time in the 1990's ... aha, a search-by-image confirms that guess http://www.internetsociety.org/what-we-do/grants-and-awards/awards/postel-service-award/photo-gallery   Hmm, funny coincidence: Steve Crocker was born in Pasadena, as was I, and Jon Postel in nearby Altadena.

While I was at Google, I did get a chance to talk with Vint Cerf for a bit (this would have been around 2010 or so, I think).  I mentioned that the last time we had worked together was over 40 years earlier.  He said something classy, like "talent will out".

More wallowing, to collect a few related links:

Here's another gizmodo article ... the 3rd photo has a good view of the Sigma7 and the console: http://www.gizmodo.com.au/2014/03/this-is-the-room-where-the-internet-was-born/ ... the guys in white shirts are SDS technicians. I wonder if that's when they came out to help us with the logic  bug that caused duplicate allocation of memory pages. There was some code (I think Charley wrote it) that used a floating point normalize instruction to find the first bit set in a word. We didn't have a floating point unit but this instruction was available with the vanilla processor. The value was sometimes off by one, but it only happened when running our system; no one else had reported it and the SDS people weren't able to isolate it. We replaced the code with a "Crocker divide" after Steve wrote a little program to find the smallest divisor that would result in unique values for each power of two (which are obtained with x & (x-1)); that code was faster. I don't know if this technique was well known at the time, but it's not surprising that Steve knew about it, as he was one of the authors of "The Greenblatt Chess Program".
