Camping Preparations

Every year since 1993, we have vacationed at the

Lair of the Golden Bear
, the family camp sponsored by the
U.C. Berkeley Alumni Association.
The Lair is in the Sierras near
the little town of Pinecrest.
We are getting ready for our annual road trip now. Our SUV will have six people in
it, plus our stuff in the used
“Yuppie Wagon”
(a small enclosed trailer with a polyethylene shell) we
just bought. My friend Laura and her son J.R. are driving their car in caravan with
us. My brother Pete is driving up with his family from Southern California.

The Lair provides the tent (canvas top, wood floor and half walls), 3 meals
a day, arts and crafts and sports and campfires, so we just have to get there and
settle in. Part of my job is to make and manage The List of Stuff.
Here are some of the items we are planning to bring to the Lair:

    Regular stuff
    - a flashlight for everyone (with fresh batteries)
    - bedding: sleeping bag, pillow, etc.
    - fitted sheets to cover plastic mattresses
    - clothes: including shorts, jeans, bathing suits, sweatshirt, jacket,
    hat, hiking boots, hiking socks, water sandals, etc.
    - 2 big towels for everyone (a bathing towel and a swim towel)
    Other stuff for each person
    - reading material, songbooks
    - camera, extra batteries, charger
    - day pack or fanny pack for hiking
    - sunglasses
    - sunscreen
    - bug repellent
    - canteen or hiking water bottle
    - toiletries in bag or caddy
    - personal medicines as needed
    - money for snacks, movies, etc.
    Stuff for everyone:
    - games (especially "Wheel & Deal", "Scrabble", and "Dread Pirate"), dice, cards,
    poker chips, game rulebooks, etc.
    - Christmas lights to decorate tent
    - tent chandelier, reading lights, extension cords, etc.
    - alarm clock
    - mirror
    - ice chest, water dispenser
    - drinking glasses
    - cheese board and knife, wine opener
    - laundry supplies and quarters, clothes line and pins
    - step stool
    - folding chairs
    - headboard
    - futons
    - pup tent
    - rug
    - trash bags
    - clay, clay tools, glazes
    - white clothes to tie dye or paint, extra rubber bands for tie dye
    - camelback water pack and water filter
    - picnic blankets
    - walkie talkie sets
    - paper towels
    - hammock
    - binoculars for birding and stargazing
    - basic tools: hammer, nails, screwdriver, etc.
    - clothes hangers
    - rope
    - medicine chest, first aid supplies
    - bear mascot
    - extra batteries
    - laptops and chargers
    - solar garden lights on stakes (to mark the trail for trips to the head in the dark)
    

I am sure I have forgotten something… I think John wants to bring his
portable N-scale model train layout so he can program it between other
activities. When going camping, I feel like I am packing the Rat’s luncheon-basket in
Chapter 1 of Kenneth Grahame’s 1908 The Wind in the Willows:

    “… after a short interval [the Rat] reappeared staggering under a fat, wicker luncheon-basket.

    `Shove that under your feet,’ he observed to the Mole, as he passed it down into the boat. Then he untied the painter and took the sculls again.

    `What’s inside it?’ asked the Mole, wriggling with curiosity.

    `There’s cold chicken inside it,’ replied the Rat briefly; `coldtonguecoldhamcoldbeefpickledgherkinssaladfrenchrollscresssandwichespottedmeatgingerbeerlemonadesodawater—-‘

    `O stop, stop,’ cried the Mole in ecstacies: `This is too much!’

    `Do you really think so?’ enquired the Rat seriously. `It’s only what I always take on these little excursions; and the other animals are always telling me that I’m a mean beast and cut it VERY fine!'”

Here is our Yuppie Wagon, waiting for its first Lair trip:

Resurrection Lilies

This is the wonderful time in summer when everything is blooming
here in the San Francisco Bay Area of California. One of my
favorite flowers is the Resurrection Lily. If you don’t know what
they are, you might see the papery yellow bulbs not doing anything all
Spring and early Summer and think they are dead. The strap-like
green leaves have long ago grown, dried up, and been
cleared away. Then, this big brownish stalk quickly rises high
and produces a beautiful cluster of pink lilies. What a delight!

Resurrection Lilies are formally called Lycoris squamigera and are in the
Amaryllis Family. They are also sometimes called Naked Ladies (because they
have no leaves).

OSCON and ServoBells

I mostly write about my husband John Plocher working on WP668, our backyard caboose.
Here are pictures from two of his more modern activities last week:

OSCON

John represented Sun and the
OpenSolaris Governing Board
(OGB) at the
Open Source Convention
or OSCON in Portland, Oregon. He came home with books, fun loot (I liked the dolphin
toys with Sun on one side and MySQL on the other, and the EFF.ORG “Defend
Blogger’s Rights” tshirts), plus vague stories of late night inflatable sumo wrestling
suits…

ServoBells

John was inspired by the
J. D. Barnhart’s “Ruby on Bells” RAD demo
to make and document his own
Arduino ServoBells,
with wine glasses borrowed from Sun Solaris Senior Director Kathy Jenks. Here is his
technical music generator (note the use of chopsticks, tape dispenser, push pins and
other ready materials):

Cactus Bloom Cycle

I have some spectacular and large cactuses in my garden, many taller than I am. I don’t
know all of their names (some came with the house). Some (like the prickly pears)
have many blooms that open all summer. Prickly pears will have
buds and blooms and fruit all at once on one plant. Other cactuses just have
a few huge flowers once a year. A cactus I planted when it was about a foot
tall has grown over six feet. It bloomed for the first time last month. The blooms
last for just a few hours and then crumple. Here are the bloom cycles of some of
my favorite cactus plants:

Window Restoration Photos

John finished restoring the first window on WP668, our backyard caboose,
last night. There are four more vertically sliding windows plus the
bay windows that slide side-to-side. This first window told us much about
how WP668’s windows were put together and how we can fix them up while respecting
their history.

Part of our work is research. For example, although most of the glass in WP668
was destroyed by vandals during storage, the few original pieces of window glass
are etched with the brand Duolite. A search found the

Types of Auto Glass Offered by PPG in 1957
web page which says:

    “Published to the Trade by PPG in 1957

    Pittsburgh Safety Glass is manufactured to meet the exacting requirements of the American Standard Safety Code for Safety Glazing Materials for Glazing Motor Vehicles Operating on Land Highways (A.S.A. Z26.1 – 1950) …

    DUOLITE SAFETY SHEET GLASS

    Two pieces of Pennvernon Sheet Glass of similar thickness laminated together with an interlayer of Vinyl plastic to provide greatest elasticity and resistance to breakage at all temperatures. Safety Sheet Glass does not have the true vision of Safety Plate Glass, but does have an equal safety factor. Duolite is not recommend for use in windshields as here true vision is necessary for safe driving. Thickness 1/4″.”

WP668 was originally built as a boxcar in 1916 and converted to caboose service
during World War II. Since 1950 is date of the referenced safety standard, this
probably means that all of the glass in WP668 was replaced with the new safety
glazing within ten or twenty years after its 1943 conversion from boxcar to caboose.
The sheets of Duolite glass are heavier and thicker than regular glass and the edges
are lined with bubbles.

In addition to restoring the first window, John has made screen inserts which
keep the air flowing through WP668 (with few bugs). Here are photos of the
window work in progress:

88% SEED Mentees Matched

Since 9 July, we have been in the SEED 2008-2009 Mentor Matching Cycle.
That is, the 84 Engineering mentoring program Participants (Mentees)
have created and prioritized their 15-name Mentor Wish Lists and I am
in the process of sequentially contacting
the highest priority potentially available mentor for each of them.
In this first 20 days (just short of 3 weeks), 74 or 88% have been matched so
far
. There are two terms being matched at the same time:

    • September 2008 – September 2009 Recent Hire Term

      which already has 21 out of 23 matched
    • September 2008 – March 2009 Established Staff Term

      which already has 53 out of 61 matched

This matching cycle is slightly ahead of where we expect it to be. Last year, we
took the average of four term matching cycles over their first three weeks. Not all
SEED terms have the same number of participants and some offer special challenges
(like having all participants working outside of the US). Nonetheless, here is
a comparison of that 2007 average against the current 2008-2009 term:

Term Week 1 Week 2 Week 3
2007 Average Term 29 matched, 48% 46 matched, 75% 49 matched, 81%
Two 2008-2009 Terms 38 matched, 45% 65 matched, 77% projected 76 matched, 90%

Restoring Caboose Windows

I am working from home in WP668 (our backyard caboose) today. WP668 is very
comfortable except when summer’s late afternoon sun hits the roof. John has been
working on restoring the caboose windows for the last week or so. He designed
screened window inserts to let in a cross breeze while keeping out bugs. The original
caboose fittings included wide metal mesh screens to protect windows against rocks
(or vandals?), not bugs. We removed the window trim during painting last year and
have gone back and forth discussing whether to buy new or restore the original
windows we have.

The difficulty is that the windows installed in 1943 have no framework other than
the caboose itself. That is, on five of the windows, the sash holding the glass slides
straight up between the inner and outer wood walls. On the bay window, the two sashes
move horizontally along built-in metal slots. We haven’t found any windows for
sale (standard or semi-custom) anything like what we have. We could go to a custom
historical window manufacturer but that would be a very expensive solution.

Last weekend, John took apart one of the windows to check its condition. It is clear
that the walls of the caboose were painted much more often than the window frames.
However, after much scraping, the wood on the first window is solid and the original
railroad safety glass is intact. So, that window will be reinstalled with new trim and
sill. The rotted original trim and sill are providing the pattern for the replacement
pieces. John said he found over a dozen rusty nails in one piece of trim. Repairs
during active rail service were hasty…

I will post photos when I have more to show…
