2017-02-19 FUJISAWA, JAPAN -- We visited Noriko's parents in Fujisawa city.

We scrapped our plans to walk Enoshima due to unexpectedly cold winds. The weather forecast has been consistently unreliable the last several days!

Surfers waiting to ride the big waves, just like the Hokusai woodblock prints.

We prayed for our parents' health at a seaside Shinto shrine.

We chatted over sashimi.

Night waves and Mt Fuji.

Pizza and paella at the Red Lobster restaurant.

Cushy ride on the Odakyu Romance express.

odawara castle

2017-02-17 ODAWARA, JAPAN -- We visited Odawara castle.

Forts and castles have been built and rebuilt here since the 15th century. The current castle grounds are much smaller than its peak at the end of the 16th century. The tenshukaku (
天守閣, originally spelled 殿守閣, the castle keep) is about the same age as me, and renovated last year.

The view from the top is magnificent. Except it started to rain!

We waited out the rain in the history museums. This is a sword hilt.

Some types of cherry trees blossom early.

Plum trees (both white and red) bloom before cherries.

Odawara has a seaport, and is famous for kamaboko. We found our favorite kind!

We rode the Odayku Romance express home. Ours was one of the oldest train sets in service, dating back to my middle school days. The old trains offer the best views, because like the upper deck of a Boeing 747 aircraft, the trains have a bulge where the engineer sits (in the old sense of "engine operator"). The newer models are single-story, and you view out through the windshield from behind the engineer.

musashino historical museum

2017-02-12 MUSASHINO, JAPAN -- We visited the Musashino Historical Museum, located northwest of Musashi-Sakae station in Musashino City, Tokyo.

This small museum takes a serious, critical view of historical events, and explains their exhibits without dumbing down the content, or neutralizing viewpoints. I found their approach refreshing.

The museum has 3 rooms: their permanent exhibit (shown below), a temporary exhibit, and a hall for lectures and demonstrations.

I learned that the villagers were transplanted here shortly after 1657 when a fire destroyed Edo (now Tokyo). The samurai families who lost their homes in the fire were ordered to relocate to what was then the outskirts of town, in order to decrease the density of population and buildings in downtown Edo. The farmers living in the outskirts of Edo were in turn pushed out to undeveloped woodlands, which became Musashino City about 300 years later.

The temporary exhibit featured household utensils spanning 100 years. Noriko and I felt our age when we recognized most of the artifacts labeled "historic".

our 1st daughter

2017-02-15 FUCHU, JAPAN -- We visited Hiroko, our 1st daughter. Hiroko is an assistant professor at the Tokyo University of Foreign Studies, Japan's top language school.

Her office room number is my birthday.

From her office window, a wonderful view (through bird-proof netting) of Mt Fuji.

Unlike me, Hiroko doesn't hoard belongings. Her office is sparse and uncluttered.

TUFS architecture is classy.

We had a quiet French lunch behind the
birthplace of Kondo Isamu, a samurai at the end of the Edo period.

disorganizing my office

2017-02-12 SAPPORO, JAPAN -- I tidied up my office. Although to you, the pictures below probably appear as if I disorganized my office.

Cleaning is crying. I threw away a hand-held massager that my mom gave me a year after I went to the United States. That was 30 years ago! A battery leak corroded the terminals beyond repair. I kept the massager (which worked great for aching eyes) for sentimental reasons. Until today. Sob ...

Move everything out into the hallway. Most of it made its way back, because I couldn't bring myself to throw it out.

I removed posters I had outside on my hallway wall. The map of Indonesia was a gift from my former roommate. I saved that map, but tearfully discarded the others.

Hard for you to believe, but this is better than before.

playing scales

2017-02-11 SAPPORO, JAPAN -- Trumpet players are expected to play over a 2.5-octave range. After 33 months of training, I am beginning to approach the upper and lower edges of that expected range.

My trumpet, like over 90% others, is a transposing instrument. For my Bb trumpet, music is written 1 whole step above, such that a concert Bb is written as C. What I call a C major scale is a concert Bb major scale. Conversely, a concert C major scale is a D major scale on my trumpet.

Shown below are a spectrogram and an audio recording of a 2-octave C major scale (concert Bb major), starting at my C4 and ending in C6, that I observed during this morning's practice. I could have started half an octave below, like I often do. This is not my best playing, merely better than average.

I want to solve 3 problems. (1) I want to stabilize my pitch. My unstable pitch is clearly visible as fluctuation in the higher harmonics, that is, the wiggly lines in the upper rows. (2) I want to transition cleanly. As my pitch ascends, some notes jump up or down. I want to stop that. (3) I want to play softer. I can play a bit soft in my comfortable range, which is the left half of the chart. As I ascend in pitch (that is, moving towards the right of the chart) I need to increase airflow, hence increasing the sound amplitude (see the red color in the lines towards the right). I want to learn to play softer, which means I am playing more efficiently.


My tiny success is that I am becoming able to play this range at all. I am happy that my chops (a collective term referring to lips, cheeks, teeth, and tongue) recover much faster than a year ago.

repair power supply

2017-02-10 SAPPORO, JAPAN -- Our family has bought oh almost 100 Apple Macintosh computers over the years. Maybe over 100. I am disappointed that my 3-year-old laptop (a 15-inch MacBookPro) came with a power supply that is poorly designed compared to its predecessors. The cable broke several weeks ago. The same afternoon I bought a new one at the local Yodobashi camera store. Today I finally got around to repairing the broken unit.

Took a while to crack the case open.

The cable broke at the base of the strain-relief collar.

Ready to tin the cables on the power supply side.

Tinned, soldered, and heat-shrunk (is that a word?). I mean "heat-shrink tubing shrunk and applied".

I gave up re-using the original strain-relief collar. The repaired unit is for office use only. Works fine as long as I don't yank the cable.
