On Wednesday, the wonderful XKCD posted a comic that coined the term "geohashing": an algorithm for calculating a (pseudo-)random trip destination based on one's location and the most recent Dow opening. The destination is the same for all readers in an integral latitude and longitude, so it becomes the location of a spontaneous gathering of other XKCD readers.

There is a wiki, several implementations, a REST-ful web service, and an "official" meeting time every Saturday at 4 PM.

I love everything about the idea. First, it can't help but be spontaneous, since one cannot know the location in advance. If someone could predict the stock market, I doubt he or she would use it to plan for an XKCD meetup. Second, it gives one a reason to travel off the beaten path (vis. the "Achievements"). Third, one gets to play with GPS, maps, and satellite imagery à la geocaching. Finally, and most importantly, one can meet other geeky webcomic fans who like the outdoors.

Today I attended the first meetup for the 40, -88 graticule. The destination was in the middle of a cornfield about 20 miles west of Champaign.

I first drove to the intersection at the northwest corner of the field. I got out and surveyed the silent, open countryside around me. There was a farmer feeding his cattle near where I parked. He looked at me curiously when I started walking along the road, holding my camera and GPS. I realized I could park closer to the destination, so I retraced the road east about half a mile to the northern edge of the field. From there, the destination was only a half a mile directly south.

I could not see anyone on the road or field—not surprising since UIUC is out for the summer and most of my CS friends were either busy or out of town— so I started walking along the grassy drainage ditch toward the destination. I had traveled about 300 yards when a car pulled up behind mine. I waved at the occupants as they started walking toward me. The internet delivers!

I returned to the road to introduce myself and shook hands all around. Kyle, Kim, and Matt were former UIUC students now living in Champaign. They hadn't expected anyone else to show up either.

We set off toward the destination, chatting about UIUC and XKCD. We had to be careful not to step on the rows of corn seedlings. It did not take long to walk across the field. When our GPS units told us we had arrived, we took some pictures of the thoroughly nondescript cornfield and discussed how we could mark the spot. I will have to bring a flag to next week's meetup.

We did not stay long, but like any trip, the journey was more important than the destination.

I love my bicycle, but its high, straight bars made riding into the wind difficult. I thought about adding drop bars to make myself more aerodynamic, but then I would have had to replace my brakes and shifters. I found the solution while reading a forum thread discussing National Bike Month. A member posted a picture of his butterfly-shaped trekking bars (also called Euro touring bars), and I knew they would be perfect.

Instead of lowering the grip like drop bars, trekking bars extend the rider's arms forward. They also offer many more hand positions, and I could attach my existing brakes and shifters to the rear grips. I ordered some bars last week and attached them this evening.

First, I removed the hardware and the old bar.

Then, I attached the new bars to the stem and reattached the hardware.

I left the bolts loose and took the bike outside to adjust the angles of the bar, brakes, and shifters. I could tell the front grips would give me a much lower and faster ride. The rear grips were slightly closer and higher than the straight bars, but it felt good to be more upright when starting or stopping.

With everything tightened, I took the bike back inside to wrap the bar with spongy grip tape. I trimmed the ends with electrical tape. The only difficulty came on the inch and a half stub between the shifters and the end of the bar. The tape barely fit between the bar and shifter housing. I had to use a small flathead screwdriver to push it through.

I took a test ride around the block. The bars feel great, and I love how unique they look. I am going to donate the old straight bars to a local bike charity.

Last week, between April 20 and May 7, I took a long vacation in the San Francisco Bay Area. It was a full week: I caught up with Eric and my housemates from last summer; hiked through Big Basin Redwoods State Park; tasted wines in Sonoma County's Russian River Valley; went to Maker Faire 2008; and biked around San Francisco.

• Day One: Big Basin Redwoods State Park
• Day Two: Wine Tasting in Sonoma County
• Days Three and Four: Maker Faire
• Day Five: San Francisco and Golden Gate Park
• Day Six: San Francisco Waterfront

I have wanted to revisit the Bay Area since interning in Mountain View last summer. I fell in love with Silicon Valley's pervasive geek culture, perfect climate, beautiful mountain parks, and vibrant urban areas. This summer I accepted a great opportunity with a company in UIUC's research park. That meant I would not have to move across the country, but I would need to find another excuse to go to California. The excuse came when I learned that this year's Maker Faire fell much earlier than last year, perfectly positioned between a paper deadline and the start of my summer job.

I booked plane tickets a month in advance and asked several friends if they wanted to join me for part of the trip. That week worked perfectly for me but was terrible for almost everyone else thanks to final exams and term projects. Fortunately, Eric was very interested in the Maker Faire, so he and his girlfriend Shannon decided to meet me in San Francisco.

I also emailed my housemates from last summer, asking if I could stay in the house during my visit.

They said I could and went out of their way to make me feel welcome. Joseph picked me up from the airport on the day I arrived, Sarah set up a couch in the garage with an incredibly comfortable sleeping bag and let me use her bike for the entire trip, Laura gave me a ride to the second day of the Maker Faire and let me use her laptop when my wireless connection didn't work, and they even had a barbecue and took me to see Iron Man. It was much nicer to come "home" to a welcoming house than an expensive hotel. I can't thank Joseph, Sarah, Laura, and Feddy enough for agreeing to let me stay and for helping to make the trip so enjoyable.

Day One: Big Basin Redwoods State Park

I spend the first morning of my vacation biking around Mountain View, Los Altos, and Palo Alto. The entire area is crisscrossed with bike paths.

That afternoon, Eric and Shannon picked me up in their rental car, and we drove to Big Basin Redwoods State Park southwest of Mountain View.

We hiked one of the shorter trails through the towering redwoods. We did not see the largest trees in the park, but the ones we passed were still very impressive.

On the way back, I showed them Skyline Boulevard and some of the spectacular panoramas bordering the Open Space Preserves.

Day Two: Wine Tasting in Sonoma County

On the second day of the trip, the three of us sampled wines from several wineries in Sonoma County's Russian River Valley. For me, the day began with a train ride into San Francisco where I met Eric and Shannon at their hotel overlooking Telegraph Hill.

From there, we drove about an hour north to wine country.

We visited four wineries: Kendall Jackson, Martinelli, Hook & Ladder, and a fourth whose name I forget because they charged a ridiculous amount for wine tasting.

The four wineries could not have been more different. Kendall Jackson looked like a French mansion complete with manicured garden. Martinelli appeared more rustic, offering wine samples at a rough-hewn wooden counter in the back of a dimly-lit barn. Hook & Ladder was much more industrial with stainless steel tanks behind a prefabricated building. The fourth looked like an Italian villa with olive trees lining the building and a mural behind the wine rack.

Eric was the most well-informed judge of the wine since he took a wine-tasting class during his senior year. Shannon and I just enjoyed trying the different varieties.

We returned to San Francisco for dinner in Chinatown. I have never seen a more frenzied staff than at the restaurant where we ate. The hostess ran full-tilt down the main aisle several times, and I cringed when she brushed inches away from fully-loaded waiters speedwalking in the opposite direction.

Days Three and Four: Maker Faire

Maker Faire provided the initial motivation for my trip, and the two-day celebration of technological creativity did not disappoint. The theme of the weekend remained unchanged from last year: to show off a huge variety of interesting gadgets, artwork, robots, and tools. However, I was impressed at how different it was from last year's event and that the two days had different exhibits and talks.

There were too many amazing creations to describe individually, but I particularly liked seeing several items in person that I had only seen online. For example, I got to try on Johnny Lee's 3D Wii glasses:

...admire Abney Park's steampunk instruments:

...confront an instrument of terror:

...and watch the motion of ferrofluid in a magnetic field:

I also took many more pictures.

Eric and Shannon joined me for part of the afternoon. They had an epic journey to the event center. First they had to return the rental car through San Francisco's rush hour traffic. Then, they had to take two trains: one to get out of the city and another to get to the event center. For some reason, the Maker Faire organizers did not advertise the train stop from which people could walk to the gate. Instead, they shuttled people from a more distant stop. So Eric and Shannon had to wait on the shuttle, then wait in a blocks-long line to get tickets. By the time they got in, they could only spend about two hours browsing the exhibits. Because of that, I don't think they enjoyed the event as much as they could have. Fortunately, they both live in Austin, Texas, so they can attend the Austin Maker Faire in October.

I spent most of the second day listening to talks. Robert Bruce Thompson discussed home chemistry experiments and asked the question, "What happened to children's chemistry sets?" The Paper Airplane Guy demonstrated, as you may expect, many paper airplanes and explained their history and aerodynamic characteristics. An engineer-turned-magician put on a magic show using homemade tricks that he learned from his father.

The headliner was definitely Adam Savage of Mythbusters fame. He talked about the many things he has made both professionally and personally. For example, he is currently building a replica ZF-1 gun from The Fifth Element. He has no plans, just screenshots captured from the DVD. He found the decal on the yellow rocket in a model rocket kit. That gave him a size reference which he could use to fabricate the rest of the gun entirely from scratch. Pretty amazing.

His talk culminated in a description of the process he followed to create a replica Maltese Falcon cast in bronze. He is definitely a perfectionist. His current casting is 10% too small, so he, in his words, "hates it!" and has to start over from scratch.

All of the talks—and Maker Faire in general—have inspired me to build something.

Day Five: San Francisco and Golden Gate Park

I regretted going to San Francisco only once last summer, so I spent the last two days of my vacation biking around the city. On day five I biked all the way across the city from San Francisco Bay to Ocean Beach and back via Golden Gate Park.

I started from the train station, then traveled roughly west on 4th, Market, and Haight streets. I passed the capitol building (with homeless people sleeping on its lawn) and the famous intersection of Haight and Ashbury.

Haight dropped me into the eastern entrance of Golden Gate Park. I passed more sleeping homeless people and was offered drugs three times. I walked the paths, passing the Conservatory of Flowers, then headed into the neighborhoods north of the park.

I resumed my westward journey, ending when I met the cliffs at the edge of the ocean. There, I got an amazing view of the Golden Gate Bridge and Ocean Beach.

I reentered Golden Gate Park from the west.

I biked about halfway through the park, then decided to get lunch in a neighborhood to the south. I returned to the park after eating and walked through the San Francisco Botanical Garden.

After leaving the garden, I biked the rest of the way through the park and along a winding path through the panhandle. I zigzagged back to San Francisco's eastern shore at the Ferry Building where I turned south to follow the Embarcadero back to the train station. I had traveled almost 20 miles by the time I collapsed into the train seat.

When I got back to Mountain View, I went to see Iron Man with Feddy and Laura. Finally, a good superhero movie! I thought it appropriate that I watched a movie about a robotic suit of armor a day after going to the Maker Faire.

Day Six: San Francisco Waterfront

On my sixth day, I met my former coworker and collaborator Marat for lunch in the city. He took me to a hidden French bistro where we talked about programming and research.

I biked around San Francisco's waterfront for the rest of the day. I did not bike as far as the day before, but I saw more of San Francisco's traditional "touristy" attractions: The Cartoon Art Museum, Piers 39 and 45, Fishermans Wharf, the Musee Mechanique [Warning! Annoying sounds!], and the USS Pampanito.

The Cartoon Art Museum had some interesting original artworks—including an original Calvin and Hobbes—and a good collection of cell animation. A TV on one wall played old Popeye cartoons in a loop. The museum was smaller than I had expected, only filling a normal-sized retail space.

I circled the dock around Pier 39. Like when I saw Alcatraz, I could not shake images of the Pier 39 course in Tony Hawk's Pro Skater video game. I saw Pier 39's famous sea lions lounging in the sun.

Fishermans Wharf was teeming with people.

I passed quickly through the crowd to get to the Musee Mechanique hidden behind the main shops. The Musee Mechanique contained dozens of ingenious coin-operated machines. I particularly liked the player pianos with their punched scores and pneumatic tubes. Unfortunately I was unable to get any pictures since the light was terrible.

The WWII-era USS Pampanito submarine was tied to the dock behind the Musee Mechanique.

I took a walking tour through the ship. I found it amazing that submariners lived in its cramped hull for weeks at a time. I took many pictures, but cannot explain much of what they show.

After that, I returned to the train station and Mountain View to prepare for my flight back to Illinois the following day.

Conclusion

I visited California to capture some of what I missed last summer. I feel I got everything I needed and wanted out of the trip and did enough in just six days to fill a summer. Thanks again to Eric and Shannon for meeting me in San Francisco and to my Mountain View housemates for their hospitality.

Now I need to find another excuse to visit.
