Roman Holiday

Well, not so much of a holiday as a business trip, but it was unquestionably Roman.

Last week I went to Rome for the IEEE International Conference on Robotics and Automation (known as ICRA to those who have reason to abbreviate it). This was my first international conference, and only my second time ever to Europe, so it was pretty exciting for many reasons.

I can't possibly summarize my whole trip in one post, but I would be remiss to post nothing until I have time to write it all up. Here are a few snapshots from the trip, and I will hopefully have time to fill in the details later.

First, here's a shot of me with my snazzy new suit and cool new camera! I wasn't sure what to wear to this conference, and all my coworkers assured me that they'd be wearing suits. Later I found out that all the Japanese people wear suits, to make up for their bad English. (Honestly, most of the Japanese presentations were pretty painful to sit through. I feel really bad for them... even though I sort of understand the reasons for it, it's still unbearable to watch somebody standing up there awkwardly struggling to read his own powerpoint slides.) Among the non-Japanese, the dress code varied wildly, from suit-and-tie to old jeans. One dude was even wearing a Whitesnake t-shirt!! :)

By the way, the camera's pretty cool too... 10x optical zoom among other features, and I love the blue case!

One of the things I really enjoyed was wandering down random streets on the way from my hotel to the conference. I spent the evenings walking around the city, too. Here's a shot of one of the old cobblestone streets (kinda rough on the feet after walking on them for a few kilos).

And everywhere you go in the city, there are statues of gods and angels watching over you. It's like the entire city is one big open-air art museum. Absolutely overwhelming.

I'll try to process and post some of my night photos over the next few days. There's so much to write about. I've got an a cappella rehearsal tomorrow at my apartment, though, so I need to clean the place up a bit tonight. :)

The city is still awake.

The city is still awake.

I came home a little early today, having found myself dashing for my last bus home every other night this week. I've been working on a paper, which has been "almost done" for quite some time now. Funny, that is. The percentage of its lifespan that a project spends in the "almost done" phase probably exceeds that of any other phase. Except, of course the "yeah, I've really been meaning to get started on that" phase.

Dutifully typing away on my laptop as my train home rocketed through tunnel after tunnel, it didn't occur to me that she would still be awake when I got home.

But she is. From the vantage point of my 23rd-floor apartment, I can see her in all her beauty...

A gemstone. A vast, multifaceted blanket of brilliance. The phrase "a thousand points of light" comes to mind, and then a part of my memory wags its finger at the thought, telling it to go away because of some vague association with President Bush... what was that all about anyway? Another fleeting and forgotten catch-phrase for a fleeting and forgotten catch-thought, which probably changed the world in some irreparable way before it was forgotten.

The cars on the expressway below add their headlights and taillights to the spectacular cityscape. I was going to say dazzling, but really it isn't. The city exhibits her brilliance in many ways -- sometimes dazzling like the brilliance of a diamond, but sometimes deeply and subtly, like the mysterious cloudy lustre of the opal.

Off in the distance, islands of flashing strobes and neon lights mark pachinko parlors, a mating call to all the burnt-out businessmen who crave that kind of mindless sensory stimulation.

Below me, the lonely river plays its games, catching the orange light of a corner streetlamp and turning it into a shower of glimmering sparks floating on the water, seen by no one but me.

Like a very old string of Christmas lights with several odd-colored replacement bulbs, the occasional blue, red, or green light can be seen, but for the most part... white.

Oh, what amazing things the city does with white. In her hands, white is not a color but an entire medium for expression. The orderly yellow-white lights on that building there, with the soft shadows, bespeak a comfortable, structured, nurturing life for the families who live there. Off to the right, powerful industrial lamps give off a cold, harsh, impersonal, stern light suitable for doing construction work or loading heavy things onto trucks. Down and to the left, a dim, orange-tinted white glow rises up from obscured streetlamps, lighting an old and seldom-used street. Off in the distance, on the side of the mountain, the white lights carry a slight yellowish cast, a faraway field of pinpoints that feels like it came out of a fairy tale.

By the time I've written this, the city has already yawned a few times and is fluffing its pillow. Every time I look, more lights have gone out. Soon the traffic lights will switch to flashing red, and only taxis will be seen crawling the streets.

And the amazing thing is, the individuals who comprise this enormous, living, breathing being, .. are oblivious to it. The city goes through her day like a well-conducted symphony -- the carefully-orchestrated fourth movement is coming to an end right now -- and every day is played out according to the score. Granted, there are nuances of expression in the way each day is executed, and every listening brings out new subtleties and developments. But the individual people who drive their cars and bicycles through the city and turn out their lights at bedtime, are oblivious to the fact that they are just cells in the bloodstream of a mighty organism far larger than themselves.

Like the small puppy dancing around and nipping at its master's heels as the old man slowly and steadily trudges down the street, the lives of the people in the city move too fast for them to notice the slow dance of the city around them.

And yet, the symphony of the city dances frenetically like a sea of roiling flames, in comparison to the serene, majestic mountain behind it. Unmoving, deeply in thought, the great dark mass behind the light show watches silently. The moods of the mountain shift slowly across the seasons, and it cannot be troubled by the fickle whims of people and cities. We may drive over it, build on it, and tunnel through it, but like flies on a horse's back, the mountain can barely be troubled to notice.

After all, where will we be in ten million years? Long gone and forgotten.

Where will the mountain be? Right here. Deep in thought.

And on that note, I'll get back to writing the thrilling conclusion to my robotics paper.

Terrible acronym

Hey everyone, spring is here and so is deadline craziness, which is one of the reasons I haven't been posting lately.

I just got an email today about this event... I thought laser plasma acceleration sounded cool, so I checked out their website. Nice acronym. :P

Japan is awesome.

Lonely Snowflakes

On my way home tonight, I saw about fifteen lonely snowflakes as they spiraled down past a streetlight, tossed around by the wind, and sailed off into the darkness. The chill in the air today certainly took me by surprise, after this weekend's springlike weather, but this was something completely unexpected.

They were beautiful.

Work Ethic

Working conditions and management in Japan suck

(Please note: I'm not ranting about my particular situation here. I think I'm luckier than most in this country.)


Ok, can I just say? The work ethic in this country is perverse. Almost everyone I know is forced to work ridiculous uncompensated overtime hours, has vacation days arbitrarily taken away, and has to submit to the most unreasonable and irrational of demands and policies. This doesn't seem to be an artifact of any one company, or any one industry, or even any social class. Everybody is forced to work way too hard here, and for no good reason.

One thing that bothers me is that this does NOT lead to an introspection and improvement of management practices, when there are SIMPLE solutions and ways to make the system better for everyone. Instead, it just leads to people going through more and more unnecessary pain.

Of course this isn't just a problem in Japan. It's happening everywhere, but Japan seems to be particularly bad, maybe because they're still stuck in their "work harder not smarter" mindset. It's like they seek out hardship here.

The BI-I-IG PICTURE - Technology fuels evil.

I'm going to go to bed now because I think I'm starting to catch a cold, but in short I think that the worldwide problem of overwork is a direct result of (a) the centralizing effects of technology putting far too much power in far too few hands and (b) the global interconnectedness of trade and communication increasing competition to an extreme level, throwing the entire system out of balance in favor of corporate power at the cost of humanity.

Technology widens the gap between rich and poor.

I'm not saying that we try to stop "progress"... that's impossible. I'm just saying that we need to try and spread it around. It's the gap between the time when technology is developed and the time when its benefits finally filter down to the poorest people that fuels so many of this world's problems. We as a world need to redirect our resources from developing technology to distributing that technology.

I know this tirade against technology sounds hypocritical, being that I do robotics research for a living. I love my job, but I also see the bigger problem. Anybody have any solutions?

This is kind of a long, three-part essay, but it presents exactly the problems I'm concerned about. You can just jump to part 3, and then read the other parts if you're still interested...

The awesome thing is that I found that in the list of references in the back of a paper I was reading today on high-speed algorithms to fit data to lines and curves...

Awesome comic!

I'd like to announce that xkcd.com is my new favorite internet comic. I've already gone through and read every panel. Twice.

Some aspects of it are reminiscent of Piled Higher and Deeper, in that there are some jaded caricatures of grad school life interspersed with nerdy humor, but I like this one better. It's not a continuous story, but rather a series of insights and snapshots of life, and random yet poignant philosophical comments.

Here are a couple pics from the site. Note that each panel has "title" text that comes up as tooltips when you mouseover the comics, which usually has something witty or interesting to say as well.

Be warned that these are addictive, so don't stay up too late reading them. ;)

Here are just a few of my like 60 favorites, just to give you a taste of what it's like:

I love the creativity of this one:



And I'm sure you all know THIS feeling:



This next one made me laugh so hard it hurt and I couldn't breathe... this is SO TRUE!!



But the thing that I love the most is that some of the comics are just really romantic. I want to dedicate this one to a certain somebody, although she probably won't understand the English. :)

"Shippo."

Every day brings with it more hilarity.

#3 - Late Valentine's ... Fish?

Yes, you read that right. I received a Valentine's gift about three weeks late, and it was ... a fish! Dad - can you tell me what this is... a trout, maybe? Leave a comment on my blog if you can identify it. :)

Valentine's Fish

Anyway, what an awesome concept. It's got crunchy chocolate balls inside, some of which are colored sort of disturbingly like fish eggs.

No idea how I can possibly come up with anything equally as unique for White Day...

#2 - Anonymous smiles on the train.

So I was taking the loop line home tonight... I think it was the second-to-last train. Lots of people, and everybody was so sleepy. A couple stations down from Umeda, this one dude down the row from me totally zonked out and dropped his ticket on the floor.

There was a group of three ladies sitting across from him - two young ladies probably in their mid-twenties and one elderly woman. They were looking back and forth among themselves, and finally the old woman got up, picked up the ticket, woke the dude up, and gave it back to him.

He apologized profusely, of course, and then they all sat in silence for another couple stations. Then, when it was his turn to get off, he bowed to them, mumbled another apology, and staggered out the door off-balance. The guy must have been SO sleepy.

Anyway, I watched this whole exchange transpire and thought it was kind of heartwarming. Then one of the ladies happened to look over in my direction, and I gave them a big grin because I thought it was great that they had helped the guy. The two younger women started giggling amongst themselves and the older woman was just beaming... she seemed so excited! Maybe it was my white boy charm, or maybe it was the fact that everyone else on the train was zombied out and she thought it was cool that someone had noticed, but from there until my stop we just kept exchanging silly smiles. :)

#1 - "Shippo"

Not 15 minutes later, I stepped into the elevator of my building, next to another elderly woman. I'd guess she was in her 70's, although I'm not very good with ages. Anyway, she had a little dog with her with the UGLIEST haircut ever and little hair accessories and things dangling off its head. I wasn't quite sure how to react... I mean, dogs aren't allowed here, and it was awfully ugly...

So, with my best tatemae smile, I commented on how cute the dog was.
"Kawaii desu ne!"

The old woman smiled at me, paused for a moment, and then, still smiling, held up the dog's tail.
"Shippo."

That means "tail."

Um... ok... not quite sure how to respond to that. Was she trying to show me something? Was it an unusually long tail for that species? Was she trying to teach me the Japanese word for tail (without even exchanging greetings or anything)? I had no idea what she was trying to communicate to me.

"Shippo desu ne..." ("Yep, that sure is a tail alright.")

Another pause...

"Erai ossan desu ne. Shigoto?"

That's a little tricky to translate in one swoop. "Erai" describes when somebody does something honorable or praiseworthy. "Ossan" sort of means "middle-aged man"... but the image that goes with it in my mind is like a sort of greasy middle-aged businessman with a faraway look in his eyes and graying hair who slurs his Osaka-ben and drinks a lot of shochu at the tachinomi bar in the train station with his sarari-man buddies so he can squeeze out that last five minutes away from his family before he has to catch his train home. I don't think I'm an "ossan" yet, although there are certainly some who would disagree. :P

Anyway, the last word, "shigoto," means work, and she was asking me if I was coming home from work.

I was actually coming home from a concert, and I was wearing a blazer over a garish t-shirt with blue jeans and my big silver bling-bling G-Clef necklace on. I don't know what kind of a job she thought I was coming home from. :P

So I said no, I was coming home from singing. And then she nodded, saying

"Ah, karaoke! Wakarimashita!" ("Oh, karaoke! I see!") and got out on her floor.

Weird weird weird. Haha, I love these little exchanges.
