Volcano sighting!

I was recently in Seattle for work and finally saw The Volcano from our office.

Fun fact: Seattle has to be the place I’ve most visited, outside of where I’ve lived — I’ve visited for work under 3 different companies, plus various trips to visit friends.

The flight from the Bay Area to Seattle is a wonder of geologic sights and I often found myself staring out the window and snapping pictures of All The Volcanoes! (My poor seat mates on this Southwest flight probably thought I was quite strange).

Anyway, here is Mount Shasta.

Book Review: The Last Island by Adam Goodheart

A few days ago, I stumbled upon a Reddit post about someone taking a photo as they flew over North Sentinel Island. I can’t recall hearing about this particular island at all, so I popped into the comments to see what the big deal was.

As it turns out, this island has one of the last remaining un-contacted tribes on Earth. Oh! Now this is interesting. It’s especially relevant, because a recently released book dives into the history of this island.

The Last Island, by Adam Goodheart, documents the author’s journey to the Andaman Islands in the late 90’s and his attempt to see the island with his own eyes.

It’s a very quick read (272 pages) and I went through it in about 2 days. After the author sharing his initial experience with visiting the Andamans, he explores the history of British colonization of the archipelago, the attempts to convert (“save”) local tribespeople, and some of the exploitation and abuse that happened as well.

More recently, attempts to interact with native tribespeople in other parts of the Andaman Islands has given insight into various issues the tribes face as they integrate with modern society. Disease is obviously the biggest, but alcoholism plays a part as well:

They live now in a restricted tribal reserve at the southern end of the island; these onetime hunter-gatherers now depend largely on food supplied by the Indian authorities. Malnutrition rates, alcoholism, and infant mortality are reportedly high. In 2008, at least eight Onge men and boys⁠—almost a tenth of the tribe’s remaining population⁠—died after drinking the contents of a bottle that they had found on the beach, which they believed to be an alcoholic beverage; it was actually a toxic chemical solvent.

Through it all, a tiny little island located 20 miles off the coast seemed to defy these attempts. It’s partly due to the treacherous reefs around the island, and partly due to the fact that British colonizers saw nothing of value on the tiny island.

Calling the Sentinelese an “un-contacted” tribe is a bit of a misnomer, since there were various expeditions throughout the last 100 years or so that involved kidnapping (!), dropping off various gifts (coconuts, pots and pans), a shipwreck in 1981 (check it out on Google Maps!), and the misguided attempts of an American evangelical who illegally landed on the island in 2018 and was quickly killed by the inhabitants.

In 1956, the Indian government passed a law that prohibited visitors from coming in contact with the island (though as seen above, this has not been strictly enforced). In more recent times, the Sentinelese have taken a more protective approach (rightly so, considering recent history).

Via Wikipedia:

The Sentinelese have repeatedly attacked approaching vessels, whether the boats were intentionally visiting the island or simply ran aground on the surrounding coral reef. The islanders have been observed shooting arrows at boats, as well as at low-flying helicopters. Such attacks have resulted in injury and death. In 2006, islanders killed two fishermen whose boat had drifted ashore, and in 2018 an American Christian missionary, 26-year-old John Chau, was killed after he attempted to make contact with the islanders three separate times and paid local fishermen to transport him to the island.

Overall, I thought the book was an interesting look at the history of this area, and an exploration into our fascination with un-contacted tribes that still exist in the modern world and the way in which we tend to idealize them (and treat them in a similar way to the animals we see at the zoo or on a safari).

Interesting uses of a Steam Deck

My Steam Deck has to be one of my favorite gadgets in the last few years. Gaming aside, the fact that it’s running Linux opens up all sorts of interesting possibilities.

For example, let’s use it to add a new feature to ArtBot… while I’m on an airplane. The screen is tiny, but oh man, it actually worked.

Getting excited for totality

We’ll be road tripping to Wyoming to see the total solar eclipse. Apparently, experiencing one is really weird.

During a solar totality, animals usually fall silent. People howl and weep. Flames of nuclear fire visibly erupt like geysers from the sun’s edge. Shimmering dark lines cover the ground.

I can’t wait!

Making maps: Using Mapbox to display 5,000 Foursquare check ins

Earlier this year, I joined a group on Meetup dedicated to creating, analyzing, and talking about digital maps. It’s organized by the fine folks at #Maptime, who have an amazing enthusiasm for all things map related. It sounded like something that’s right up my alley, considering all the time I spend thinking about maps.

Last night was project night. All sorts of folks were there, working on complicated issues such as transit, land use, green space, climate effects. It’s kind of inspiring!

I went to focus on some less lofty goals — I just wanted to get some experience playing with a JavaScript mapping library created by a company called Mapbox. My goal was to get the library up and running and then use it to display some geo-encoded data from a service I happen to use a lot: Foursquare.

It’s no secret that I really like Foursquare — mainly for keeping track of our adventures far and wide. I found a helpful PHP library for converting Foursquare (and other social networking) data into GeoJSON, which is needed by the JavaScript mapping libraries. After a couple of hours of hacking around, I got something up and running!

Screenshot 2015-02-04 20.06.29Pretty neat stuff! I have some ideas on how to improve this and some additional data that I want to show in the future.

 

Klutzing around Europe

This story will make my Mom proud.

When Kerry and I were at the palace of Versailles earlier this week (viewing 300+ year old artifacts), we went on a tour of King Louis XVI’s private apartment.

While taking a photo, I backed up into a rope that I suddenly felt go slack. A second later, a gigantic “BANG!!!!!” echoed through the room we were in and the tour guide said “oh dear!” with a hint of panic in her voice. I’m pretty sure my heart stopped for a beat or two as well.

Turns out, I only knocked down a pylon that was supposed to separate a non-public area from a public area.

Good thing, because 20 minutes later, we saw an ugly ornate dresser (that was designed to never open — simply a decoration piece) that sold at an auction for $11 million dollars!

The final flight of the Space Shuttle Endeavour

STS-134 NASA Tweetup

STS-134 NASA Tweetup and the final flight of the Space Shuttle Endeavour

On April 28th and April 29th, 2011, I was fortunate enough to participate in the NASA Tweetup for STS-134. It was to be the final flight of the Space Shuttle Endeavour and the second to last mission in the Space Shuttle program. I traveled to the Space Coast from San Francisco and spent three fantastic days with fellow Twitter users and enthusiastic space geeks at Kennedy Space Center. Things didn’t always go as planned (you’ll see), but it was an experience that I’ll cherish and never forget. Godspeed, Endeavour.

Some things are better left unsaid

(I’m currently on a plane, en route to Florida for the STS-134 NASA Tweetup.)

A British couple behind me are looking out the window and ask a flight attendant if that’s the Grand Canyon below us and to our left. She says yes, so I look out and see that it’s actually Valley of the Gods in Southern Utah (neeeeerd). I turn around to say something, right as the husband says, “Oh, that is so great! I’ve always wanted to see the Grand Canyon!”

Alright then. Just smile and turn around, Dave. 🙂

Good grief, we geologists can (nearly) be assholes sometimes!

Christchurch – Then and Now

EDIT: The Big Picture is featuring powerful and scary photos of the damage.

We’re just starting to find out how bad today’s M6.3 earthquake in Christchurch, New Zealand was.

A former professor of ours when we were in New Zealand in 2006 dropped us an email this evening and let us know that it was going to be bad. He also informed us that the iconic Christchurch Cathedral in the center of the city was destroyed.

It was an absolutely beautiful building – originally built in mid-1800’s and completed in 1904.

As we saw it in 2006:

And as it lays today:

My heart goes out to everyone in Christchurch. This is going to be fairly bad.

Choo choo!

We were supposed to take the Amtrak Coast Starlight train down to Southern California, but it was severely delayed due to bad weather in Oregon and Washington. Changed trains, taking San Joaquin to Bakersfield and then a bus to Los Angeles.

Here we go!

Man, wouldn’t it be nice to have a high speed rail system in California?

Sneak attack!

We’re 3/4 the way through a bottle of wine when we hear over the intercom, “Remember folks, you’re not allowed to drink your own alcohol on the train, or we’ll remove you and your alcohol from this train.” Crap!

On another note — the Central Valley is a lot more fun to look at when you aren’t driving through it.

TSA Checkpoint Sign

tsa-sign.jpg

Oleg Volk created this TSA checkpoint sign in 2008, which is now getting attention due to recent abuses by the organization.

Interestingly enough, the social location service Loopt is offering 10 iPod touches to people who check in to an airport using the app on November 24th, and tweet about being pat down by the TSA.

As a slight gift to opt-outers out there, Loopt is giving away 10 iPod Touches for TSA touching. Just check into your airport on Loopt* on Wednesday, November 24 (with iPhone, iPod Touch or Android), share a bit about your experience, push it to Twitter with the hashtag #touchedbyTSA, and you can win an iPod Touch. That simple.

Another TSA problem? Data collection

Another problem with the TSA? Lack of data collection. A former assistant police chief writes on the potential for passive discrimination, due to the TSA’s lack of data collection:

Over the last fifteen years or so, many police agencies started capturing data on police interactions. The primary purpose was to document what had historically been undocumented: informal street contacts. By capturing specific data, we were able to ask ourselves tough questions about potentially biased-policing. Many agencies are still struggling with the answers to those questions.

Regardless, the data permitted us to detect problematic patterns, commonly referred to as passive discrimination. This is a type of discrimination that occurs when we are not aware of how our own biases affect our decisions. This kind of bias must be called to our attention, and there must be accountability to correct it.

One of the most troubling observations I made, at both Albany and BWI, was that — aside from the likely notation in a log (that no one will ever look at) — there was no information captured and I was asked no questions, aside from whether or not I wanted to change my mind.

Given that TSA interacts with tens if not hundreds of millions of travelers each year, it is incredible to me that we, the stewards of homeland security, have failed to insist that data capturing and analysis should occur in a manner similar to what local police agencies have been doing for many years.
