Channel Islands National Park

Last week I was in Los Angeles, CA for SIGGRAPH, and though I discovered that I far prefer New York to LA (sorry, Angelinos) I did get something great out of it — a trip to Channel Islands National Park.

About 30,000 visitors step onto its shores every year, making it one of the least-visited national parks. It consists of five islands of varying sizes, and we stayed on one of the larger ones. There were a few dozen other campers we saw, but the vast majority of people on the boat were day-trippers.

We “set sail” at 8 am with Island Packers, who were fantastically efficient and a pleasure to travel with despite their apparent monopoly on service out to the islands. Upon landing, the campers were required to get a brief orientation from the live-in park ranger describing their pack-in pack-out policy and the fact that we should never leave zippers exposed as the island’s ravens have learned to unzip backpacks.

With wetsuits rented from Ventura Dive and Sport, plunged into the icy waters (ok, they’re not icy, but they’re pretty frigid compared to the warm Red Sea). The kelp beds were amazing, stretching below beyond visibility and then tangling at the surface, creating an enormous labyrinth of giant leaves. Their bases covered in sea urchins eating away at the tendrils. On the second day we saw a couple of stingrays, and a school of fish thousands strong trolling the area. I had hoped to swim and play with the local sea lions, but they weren’t particularly interested in us apparently.

While not freezing in the water, we hiked the many trails, perching atop the various cliffs overlooking the many harbors. And when not hiking, we ate and watched the chihuahua-sized island foxes looking for food and fending off the comparably-sized ravens.

It was a fun excursion, and I hope to go back for more diving and exploration of the islands. During the year they see countless whales and dolphins, and organize dive trips. Oddly enough, I found out about it two years ago from an in-flight magazine on my way to a KAUST orientation meetup. Chalk one up to the in-flight magazine!

I must admit, at times, looking down at the bright blue water, and ships coming into harbor, I felt a little bit like a pirate.

I’m living in New York, New York this summer while I work at IBM Research. From the offset, I was skeptical of the city. Any city, really. I grew up in Colorado, where the population of the entire state is less than a third of that of the NYC metro area.

The first week was a little rocky, but mostly because I was unfamiliar with my neighborhood and wasn’t sure where people went to do their grocery shopping, to eat, grab a drink and so forth. By Monday of the following week, I knew my commute to work like the back of my hand, blending in among the real New Yorkers with the disaffected forward-looking stare that says, “I just want to get where I’m going, pal.”

When I first arrived, I was on a red-eye flight and got in around 9. I had contemplated taking a taxi to my place, both wanting to have ridden in a New York City Yellowcab and not wanting to deal with public transit, but when I got there I felt like I ought to hit the ground running. Riding on the bus, I examined the faces and demeanors of all those around me, wondering to myself which best embodied the New Yorker. On the bus, off the bus, transfer to another bus in Harlem. The name of the neighborhood brought to mind poverty and violence, and frankly, as a wet-behind-the-ears exhausted-and-irritable honkey with luggage, I had no idea what to expect. Getting off the bus and walking to the transfer, I passed the undeniable odor of marijuana, urine, drunk and irate homeless people and so forth. Bear in mind this was about 10 am on a Sunday. But while waiting, I realized something sort of magical about the city — no one cares. If you don’t get in anyone’s way or make yourself particularly noticeable, but just wear that look of just wanting to get where you’re going, no one will notice you’re there.

I had imagined that it would be a city of all kinds (which, it really is) but also a city of all kinds of rude. This was a major misconception. Though most citizens would not return a “hello” from a stranger on the street, most will help with directions when asked and apologize when they bump into you. I had hoped that at some point during the summer I would accidentally bump into someone who would then call back at me “hey, I’m walkin’ here!” This seems unlikely to happen at this point.

There are some stereotypes that are true to TV life. Attractive, busy and exasperated professional women are in abundance, a la Liz Lemon of 30 Rock, for example. There is a certain level of dress that seems to be expected here, even on the street. Most men wear shirts and resort to jeans as their most casual and most women, at least this time of year, wear dresses, though I think that might be because of how outrageously hot it can get.

The New Yorker’s hatred of tourists is a uniting factor, and something that I began to understand almost immediately. It can be easy to get distracted by the enormous buildings, and visual stimuli, but most inhabitants pass these things every day and are just on their way to work, or dinner, or a friend’s. I’m gaining a sense of what parts of the city to avoid for this reason – it’s very frustrating to get stuck behind a slow-walking tourist who’s aloofness makes him meander windingly down the sidewalk, impossible to pass. Times Square is a death trap — three blocks of fanny-pack-wearing fathers trying to decide what to see next, keep track of lagging children and generally getting in everyone’s way. But, let the tourists have Times Square.

Don’t take too long here. A friend who shall remain nameless visited me here, and used to the slower-paced life in Boulder, CO, she pondered what she wanted from a pizza place only after we had gotten to the front of the line. On another occasion, she flip-flopped on her order. To be fair, these places weren’t extremely busy, but it brought to light the fact that there’s an expectation here that you have been to a place before, know exactly what you want, and can complete your transaction in less than a minute. In some ways, this is a charm that I like; there are many places to eat here, but I’ve quickly developed preferences and can walk into my favorite pizza place and make my order like a regular.

My favorite things about New York couldn’t be experienced in a vacation here. When I first moved in, for example, I was so pleased with the view from my place. Not that it’s particularly incredible (I live on the Upper East Side and I don’t know what sort of reputation the neighborhood holds as far as views), but I like it all the same. I look out my window and I see dozens of different buildings that I would call skyscrapers, all designed differently, peppered with garden terraces and charming signs of age. The jagged horizon is somehow enchanting, and my curtains always stay open. At night the neighboring buildings provide a soft and diffuse light, and different patterns of lit windows.

I love walking down certain streets and being able to see down the avenues, the tiny separations between giant buildings. Properly positioned, you can sometimes see a mile or so before a hill obstructs the view. It reminds me of a project I saw to create a horizonless map of Manhattan.

The last few hours of sunlight in the day are perfect. People talk about the Colorado sky, or the sunsets we have, but I’ve never seen light quality quite like this. It’s a beautiful golden warmth every day without fail. It makes me want to curl up and take a nap, or stretch out on the lawn and enjoy the end of the day. In the park, this deliciousness is only compounded by the reservoirs, the heavy trees and residents playing frisbee, picnicking and taking walks along the paths. It’s a beautiful time, and there’s an odd sense of community to it. I’ve often wondered if such a place existed, where there isn’t any one group that’s out and enjoying the place, or even a tight-knit group of neighbors. But there is a dense packing of total strangers who can come to the same place and enjoy the grass and the outdoors.

Almost most of all, I love Central Park. I was excited when I found my place because it’s a mere three cross-town blocks from Central Park. I bike around there almost every day, and it’s almost always a treat. There are hordes of runners, cyclists, rollerbladers and even a few cross-country skiers. As a cyclist, you have to keep a watchful eye on the bipeds you’re passing as they sometimes have a tendency to step out in front of you. We largely ignore crosswalks, and only the few cars on the road observe them. There are some sections that are filled with horse-drawn carriages, bikeshaws and more adventurous tourists who decided to rent a bike and ride around the park, but you make do. Sometimes it’s actually quite a thrill to be riding as fast as you can and dodging these obstacles and having a little friendly battle with other riders. This, too, is a nice feature about riding here — no matter what your level, you can always find an equivalent cyclist for a little friendly competition and motivation.

Biking in the city is also a pretty big rush. In the morning hours, most of the usually-busy roads are ghost-towns, but seventh avenue at 7 in the evening is a sea of taxis. I was riding down one day to Penn Station in the evening, catching a train out to Long Island to see a friend. A bicyclist will make it down there faster than a taxi, but it’s not for the faint of heart. Sprint, breaks, sprint, dodge pedestrian, coast, zip between cars, breaks, sprint. There are no bike lanes, but rather only the spaces between cars. The upside of this game of Frogger is that you can zip out between any two lanes where there’s space. I’m not quite sure how cab drivers feel about us, but I imagine that if nothing else, they’re quite used to people with a death-wish.

Had I never spent more than several weeks here, I never would have discovered what I love about the city. These are the things one does and notices not when trying to visit the Met or Times Square or the Empire State Building, but only when you’ve enough time to be alright with not packing every waking hour or weekend with a trip to somewhere new and exciting. This is the meandering life, and enjoying it.

Women Drivers

Living at KAUST comes with certain privileges not extended to Saudi at large. For example, women do not have to wear abayas on campus, or even scarves to cover their hair. Men and women are allowed to talk openly, although there are restrictions on fraternization. Also, women can drive.

Thus, it occurred to me recently – if you’re a woman driver in Saudi, you get arrested and then who knows what else. If you’re a woman driver in the US, you get a discount on your car insurance.

 

Heartsaver Course

A fellow student recently arranged for a number of us to take a CPR and AED (automatic external defibrillator) short course. I think every one of the 11 KAUST students is either an avid diver and/or snorkeler.

I can’t speak for everyone, but I know for my personally it was because I wanted to be able to be a better dive buddy. (In PADI and all diving certifications you’re supposed to dive with a buddy for both safety and fun.) Although we always take appropriate precautions when diving, it can still be a dangerous sport. We all feel like learning CPR and how to operate an AED were easy steps to mitigate some of this risk.

During dive training, we have to practice some emergency maneuvers, but I always had this lingering curiosity about whether or not it would come back to you naturally during an emergency situation. Once while diving, my friend Noah took off his tank and regulator and swam over to our friend Luca and signaled that he was out of air, asking to use his alternate air source. While it’s a simple act to share your air, seeing another diver pop up needing air would be quite a surprise.

That said, I realized after the course that we were at least better prepared for unforeseen accidents than we were when we started.

 

The Life Aquatic

A while ago, I saw an xkcd comic about being stranded on a desert island – looking out at the vast, perfectly flat blue infinity, struck by the lack of anything worthwhile.

xkcd's Desert Island

Had I been stranded on a deserted island six months ago, this would have absolutely been me. Well, and without goggles, it would still be me, but that’s neither here nor there.

As I live in Saudi Arabia, activities can be… sparse. There’s cycling and sports, but for the most part it’s too hot to do anything until the evening. In January I first joined some of my friends on a dive trip of theirs – I was only snorkeling, but they assured me there would be plenty to see. Growing up a good 1500km from a large saline body of water, my experience had been rather limited. When I finally got ready, and put my head under water, my head popped back up about half a second later, shouting to my friends, “Holy crap! There’s fish everywhere!”

My friends just sort of looked back at me as if to say, “yeah… about that – that’s why we come.”

From that point on, I’ve been hooked. I have since gotten dive-certified, and gone a few trips. Few things are better than getting to explore a world unseen by most people, sometimes seeing reefs so random and remote that it’s unlikely that people have even been there at all. On every boat trip, we pass uncountably many shallow reef patches, that extend for kilometers – they really are sprawling, massive underwater cities.

A few weeks ago, I got to go on a truly fantastic trip. The Marine Science department at KAUST tags and studies whale sharks, and every so often they take along “tourists.” We saw between 5 and 7 unique sharks, the longest of which was about 6.5m (20 feet), though apparently they can grow to be over 12m (40 feet). Roll clip:

How this worked is we had two boats (one filled with researchers and one filled with us tourists), and if either boat spotted something, they’d sound the horn, and everyone jumped in. As such, we would all sit on the edge of the boat, fins on, masks ready – just in and out of the water all day. Once in, the sharks tended to swim pretty fast – they seem to be barely exerting themselves and we’re swimming as fast as we can. And, if they don’t care to outrun us and want to get away, they dive beyond our reaches.

On this same trip we saw a lonely sea turtle, about the size of a dinner plate. We all hopped in the water and had turns getting our pictures taken with him. Honestly, I felt a little weird about picking him up, but he really did not seem to mind it. It does violate a widely-followed rule among responsible divers – touch nothing (unless you really know what it is and that it’s not going to damage you or it).

We also saw a “pod” of three dolphins; they often appear briefly on these boat trips, but usually scurry off pretty quickly in our experience. On this occasion, though, as we were already set up to be hopping in and out of the water at a moment’s notice, we did try to swim with them. They mostly stayed about 6m below us, and were much more difficult to keep up with than the whale sharks. That said, fortune favored the persistent, and after about 15 minutes of some of my hardest swimming, I managed to spot them and get within about 2m (6 feet) of them as they surfaced. One was badly scarred across his back, but the other two were untouched. They came up for a quick drink of air, descended a few meters, did a somersault underwater and then looked at me as if to say, “Oh, you can’t do that, can you?”

It’s hard to take in the incredible gravity and beauty of the sights, let alone when swimming as fast as you can and perpetually out of breath. I’m glad I got the chance, and I hope to see more aquatic life, but there is definitely a reason it’s remote. Consider this: in hiking, the highest I’ve been is just over 14,000 feet, but the limits of recreational diving is a mere 40m (130 feet) and that requires even more specialized training. Consider, too, the Mariana Trench – which is less accessible: the deep sea or space?

Since the opening of the KAUST beach, we’ve explored much of the reef, sometimes to the dismay of the coast guard. We take precautions – never going alone, bringing a dive flag, and knowing our limits. Floating along in the warm water, seeing thousands of fishes, swimming around is enough to make anyone want to play Jacques Cousteau.

Snorkeling

For the past semester, many of my friends here have been enjoying the Red Sea, diving regularly. One even went on a two-week research cruise, making three to four dives a day.

‘What,’ I wondered, ‘could possibly be the fascination?’

Growing up in Colorado, playing around on the beach meant going to Boulder Reservoir, which isn’t much more than an enormous swimming pool. Just not much remarkable about it. The only real beaches I had been to until now were in San Francisco and Japan, and the novelty wore off pretty quickly.

This last weekend, I decided that I ought to give it a try, and not being certified for diving I went snorkeling with my friends. We drove to a private beach (which was a treat in itself – men and women can mix, and music plays over the loudspeakers. These are things I’ve learned to not take for granted), rented gear and got in the water. On the dock, I was excited when I saw a small coral growing in the shallows. It couldn’t have been more than 10 centimeters in diameter but thinking about exploring the beach for more such treasures was enticing.

We waded out and put on our flippers, and then our masks. I dipped my head down, ready to explore, and instantly my head popped right back out of the water. “Guys! Guys!” I shouted to my friends. “There’s a freakin’ million fish here!” They chuckled knowingly, and I realized this is what they came for.

I just could not get in the water fast enough. There were so many fish I had never seen except for in aquariums, brightly colored, quick, and just stunning. Thousands of them from deep blues to iridescent purples, all swarming around beautifully-colored coral and anemones. All told, I spent about four hours tooling around the reef, examining fish at the cleaning station, clownfish in their anemones and predators lurking near the surface.

On leaving I instantly felt like a tree-hugging hippie, and felt a need to protect the ocean. Ok, sure, it was a bit short-lived and I feel like someone who’s hopped on a bandwagon, but it’s an incredible world down there. You see shadows off in the “distance” (though it’s usually only 30 feet away) shimmering and swimming around. Floating in the sea, weightless, above the sheer cliff faces of 20, 30 or 40 feet is a unique sensation. I tried to compare it to hiking and climbing mountains, but it occurred to me that unless I learn to base jump, I will never see that kind of geographical structure from the same relative perspective – hovering above it.

Between dives (well, my friends were diving while I was snorkeling) we’d pull out a book of Red Sea fish and try to find all the ones we’d seen. The camaraderie of stories of dives past and fish seen was nearly as satisfying as the experience of being in the water like that.

I’m exploring getting certified (either through PADI or BSAC – we have both available here) so that I can join my friends on deeper adventures, but in the mean time I’m going snorkeling as often as I can. Forgive the pun, but I think I’m hooked.

Monkey Business

Nagano (well, Yudanaka) is famous for it’s “Monkey Park,” an open space where Japanese Macaques relax in large groups in the natural hot springs. Visitors can walk among them as they graze, groom, and occasionally, fight.

DSC_0023.NEF

The younger monkeys are pretty playful, climbing ropes and poles, and rough-housing with one another. The adult monkeys seem more interested in eating the food provided to them, a mix of barley and other grains. There seemed to be some areas used mostly by families (these were inaccessible to human visitors) and others that seemed to be dominated by younger bachelors. Fights would break out from time to time, but nothing too serious.

DSC_0052.NEF

Japan is known for their natural hot springs, and the monkeys take full advantage. The day I was there, it was about 3 degrees Celsius, and the water was pretty tempting.

You can get pretty close to these brazen animals, but do not touch. Occasionally they will grab onto you, but I only saw one instance of this; a group of us were watching a couple monkeys playing and banging against a sign, when an attention-starved lad came up and tugged on one man’s coat to get his attention. Still, they’re pretty aloof to our presence for the most part, and will walk and eat within a few feet of you.

DSC_0106.NEF

I kept thinking of them as terrestrial Ewoks, or furry seven-year-old human children, but the opposable toes are kind of unnerving. They often appear so human that it’s hard to remember that they’re still very wild.

DSC_0239.NEF

They cry and scream at one another, but these noises serve as low-priority warnings more than anything else.

If you even get a chance to visit, take full advantage. Best US$5 I spent in Japan. More photos on flickr.

日本!

I arrived in Japan yesterday for SIGGRAPH Asia 2009. It’s been a long time since I’ve been here, and it’s nice to be back.

It turned out that a few KAUSTicans were on the same flight as me, and we had a good time talking shop while waiting for flights. Good guys – I look forward to hanging out with them at the conference.

It wasn’t until I stepped off the plane and saw that my travel companions didn’t look to be immediately at ease in this country that I realized that Japan is almost a second home. Outside of the US, it’s the country in which I’ve spent the most time, though Japanese is not my strongest second language. Still, I was able to pick up right where I left off in terms of daily life without missing a beat – it’s a different city, but the people and places are recognizable.

Glad to be back, Japan.

 

Flood

Yesterday morning, I woke at 6:15 to the all-to-common fire alarm. Prepared to sleep through it if necessary, I went to my window to check for smoke or anything that might indicate that this wasn’t one of the dozens of false alarms. What I found was rain.

DSC_0052.NEF

Rain like cords was falling in Saudi Arabia. The streets were wet, and excited, I ran to get my camera and started taking pictures. I threw some clothes on, and ran around campus to try to document what I believe to be a very rare event here. I called several of my friends to make sure they were awake and witnessing this.

The rain let up about 7:30, and soaked and I tired I headed back to my building to get some sleep when I encountered several other students who also wanted to just feel the rain on their faces. We walked around campus to see it wet, but ended up surveying the damage. Students had ceilings collapse, water running out of light fixtures, flooding in their apartments – the list goes on.

DSC_0264.NEF

A sunken area of campus had turned into a lake (based on what it’s like when it’s dry, it must be 4 meters deep in some places), and some roads had become impassable rivers. Encountering a couple of students on motorcycles unsure if they should try to cross, I was reminded of Oregon trail. In the end, they forded the river.

DSC_0328.NEF

Tyler and I moved on, the water now thigh-high in the middle of the road. Cars’ mufflers were bubbling through the water, and one had to worry about the wake of passing cars. The womens’ residence was evacuated, and many families packed their kids in the car and left in search of higher ground. The timing was sweet and sour – it was the last day before break and school got cancelled on account of rain, but most students were leaving the country for the week, and some will return to find unlivable and extensively damaged homes.

DSC_0352.NEF

Rains like these are extremely rare in the area, and so I understand the lack of preparation. I don’t understand the shoddy craftsmanship of the homes, but that’s a running issue. Tonight’s Thanksgiving dinner will be a reflective one for certain. One exasperated student, waking to water pouring on him, household wiring fried and water running down the stairs like a waterfall felt that this was the last straw. He seemed to be set on the decision to return home at the earliest possible time.

It seems he’s not alone, and the school is expecting a non-negligible portion of the students to not return after winter break, though some are talking about not returning from Eid break at the end of next week. I hope for all our sakes and for the sake of the school, that the administration can refocus, get their act together and get their sometimes incredible mismanagement under control. We all came because we wanted to see KAUST succeed, and we hope it still can.

DSC_0387.JPG

That said, I would like to offer praise and criticism; the response from emergency services was what I’d expect in a modern country. Water tankers were on the streets, pumping out massive amounts of water, within four hours of the rain. The fire department helped evacuate a number of families, and each student was actually contacted by phone to make sure he had a livable apartment for the time being – those who did not were moved to safe lodgings. My criticism is this – why are not all of our other, very real concerns and problems not pursued with the same tenacity and efficiency. Why did it take a small disaster for KAUST to shine?

I took some more photos as well.

I’ve been around the block a time or two (or more) with subversion, but until recently I had limited experience with git. Sure, every now and then I’ve used it to check out projects, but not for my personal use.

No longer. And as of right now, I don’t have any intention of using anything but git for personal development.

Last week, I held lecture for parallel programming and I talked about using subversion for versioning, and I began to suspect that something was horribly wrong. Questions started springing up – where does the repository live? Am I calling svnadmin on my own machine? Where do I check out the repository? Though there are answers to these questions, for many things, such a model just doesn’t make sense.

If I’m working on a project that I’m not syncing between several computers, but I just want to have different stable versions and to try different crazy ideas using branches. It mitigates the cost of reverting drastic changes to code.

Use Case: You’re showing someone your code, and want to show off a neat feature you’ve made, or a problem you’re encountering, something about the project, invariably you’ve run into a problem where it doesn’t compile at the moment. You type furiously, trying to find and undo the most recent changes, but to no avail – there is no hope of getting it to compile in the 5 minutes you have someone’s attention. Enter version control. Revert to the last working copy and victory is yours.

In fact, just today I was asked if I could pull up some code I had been working on to show to a professor. Unfortunately at the moment it wasn’t compiling but was able to switch versions in 20 seconds and show off some very recent work from earlier in the day, thus saving face.

Use Case: You’ve got some crazy idea for an implementation you’d like to try out, but are worried about reverting back all the massive changes you’ll have to make in the code. Worry not! Create a new branch and feel free to change your code in every way you can think of and not lose other branches under development.

Use Case: You’ve got multiple versions of code each implementing the same basic algorithm but with different mechanisms, techniques, etc. and have to turn it in as part of a project. Just archive the whole directory (in a tarball or zip) and the user who unpacks it has access to every version your code has been in. Each branch, each stage of development. And very light-weight to boot.

I can’t speak for others, but I will be using git for the foreseeable future as it’s incredibly easy to use and alleviates many of the problems I encounter regularly with development.
