This is a fantastic exploration of how to optimize really resource-intensive software. The memory footprint of the parsed data is completely insane.

Some reflections on my roadtrip across the western United States

4 Comments

Last week, I stood in the middle of the caldera of a supervolcano, walked on rocks billions of years old, and traveled back in time simply by driving down a mountain. I looked a bison in the eye at five yards. I witnessed the final resting place of a 12 million-year-old fossilized horse buried in volcanic ash. I saw a rainbow emerging from a mighty thundercloud — powerful with a little bit of tender. I talked civilly with red hatters in red states and found some common ground at least. I drove across the western United States, from Iowa to Oregon, over the course of 10 days. Here is some of what I saw and learned.

Biggest surprise of the trip, part 1: The Bighorn Mountains and The Bighorn National Forest. I had planned to just drive though, up and over, on my way to Yellowstone, but I ended up stopping here for quite a while. The Bighorns aren’t as spectacular as Yellowstone or some of the other park, but it’s a hell of a lot less crowded. I’d go back and spend a few days here easy.

2018 Roadtrip 01

Surprisingly, despite spending 57 hours in the car, I was not bored a single minute of my trip. I marveled at the landscape, played music, and thought. I thought a lot. I expected to listen to a bunch of audiobooks but only managed to finish one I was most of the way through and the first third of another…the landscape was just too distracting most of the time. My experience leads me to believe I might be a good candidate for a solo Mars mission (aside from the one-way thing).

Animals seen on my trip, a partial list: rabbits, prairie dogs, antelope, ducks, geese, pelicans, pheasants, a moose, a wolf, elk, bison, deer, and a bunch of birds I couldn’t identify. The prairie dogs sat near their holes peeping at each other…it was really cute. The moose was a juvenile male in Yellowstone who looked lost & confused; he trotted alongside the road for a bit, then swam across the river and took off into the woods. I was apprehensive about not seeing a bison on my trip, but I shouldn’t have worried…Yellowstone was lousy with ‘em. Pro tip: bring a good pair of binoculars, possibly left over from eclipse-watching.

Yellowstone was one of the highlights (with a caveat that I’ll get to in a second). A single park containing all these different landscapes, from volcanic wastelands to mountain peaks to verdant river valleys to evergreen forests to grasslands…it’s a geographic marvel. But here’s the but: it’s also really crowded in the summer. At times, it felt like a nature mall, with herds of consumers moving from the bison shop to the geyser store. Reminded me a bit of my experience at the Louvre, itself a wonderful place too crowded to enjoy.

2018 Roadtrip

Final roadtrip stats: 2748 miles driven in 10 days and a total of 57 hours in the car. 718 photos and videos taken. I visited seven states — Iowa, Nebraska, South Dakota, Wyoming, Montana, Idaho, and Oregon — and spent at least one night in each save Idaho. Lowest point: 810’. Highest point: 11,070’.

Somewhere west of the Missouri River, which separates Iowa & Missouri from Nebraska & Kansas, the dominance in the eastern US of human activity & organization gives way to geology and geography. Even in the sparser areas of the Midwest, you look down from an airplane and see the Jefferson grid: square parcels of land, each with a group of buildings contained somewhere within it. Further west, hills and mountains and volcanoes and rivers and streams and forests and plains dominate the landscape and how people move within it. The West is not yet tamed, not by a long shot, and acknowledging this goes a long way toward understanding the people who live here.

Biggest surprise of the trip, part 2: High altitude wildflower meadows. When I stopped my car at a scenic overlook at 9400’ in the Bighorn Mountains and saw a path down a gentle slope through a meadow of wildflowers growing very close to the ground, I didn’t think a whole lot about it. Pretty scene, right? I grabbed my daypack from the car and as soon as I stepped down onto the path and into the meadow, this amazing smell sent me reeling. For 20 minutes, I walked in an olfactory daze to the crest of the next hill and back. OMG, what an amazing sensation…a definite high-water mark.

2018 Roadtrip

The speed limit on the freeways in South Dakota, Wyoming, Montana, and Idaho was 80 mph. On some rural undivided two-lane highways, the limit was still 70 mph, which I found astounding. But the lanes and the shoulders were way wider than in Vermont, the roads flatter and straighter, and traffic was few and far between most of the time. Still, even just that little extra speed really cuts down on drivers’ potential reaction times.

I had high hopes for the Badlands, and it lived up to the hype. Magnificent desolation, accessible, and not super crowded. I could (and probably should) have spent a couple of days there easy.

2018 Roadtrip

Food was not a highlight or a focus of this trip, mostly because I didn’t spend a tremendous amount of time seeking out good places to eat. I had some Thai lettuce wraps w/ bison in SD that were pretty good, some just-fine sushi in Missoula, and a delicious tostada scramble in Rhododendron, OR. Maybe the best thing I ate was a homemade breakfast burrito I bought at a gas station in Red Lodge, Montana. It was a struggle to find non-meat things to eat — I’m not a vegetarian, but man cannot subsist on burgers & hot dogs & steaks & BBQ for a week and a half w/o GI discomfort. With some notable exceptions, food in the US is more homogenous than ever…you can get anything almost anywhere.

Biggest surprise of the trip, part 3: The hosts at the B&B I stayed at in Wyoming advised me to enter Yellowstone via the Beartooth Highway and I am so glad I took their advice. The 68-mile drive was called “the most beautiful drive in America” by former CBS correspondant Charles Kuralt and he might be right. At the top of the pass, you drive just short of 11,000’ above sea level; I climbed above the 11K mark for a stunning 360° view of the entire area. Reader, I may have done the arms-wide-on-the-bow-of-the-Titanic gesture on top of a rock at the top of the world…no apologies.

2018 Roadtrip

About 5 minutes after I checked into my B&B near Cody, WY, I looked out my window to see a rain cloud off in the distance with a rainbow coming out of it. Chuckling, I asked my host if that was a common occurence around here. “Pretty much,” he replied, “especially with climate change.” A life-long resident of the area, he went on to explain that it rains a lot more there now than “20-30 years ago”. “See all that grass out there? It’s supposed to be brown this time of year.”

Several people told me before my trip that Devils Tower was worth the effort, but as I spotted it off in the distance on my approach, I had my doubts. But as it got closer, I realized they’d all been right. Totally crazy geological thing worth seeing in the flesh.

2018 Roadtrip

At a gas station in southern South Dakota, a man noticed the Texas plates on my rental car and asked, “What’s the price of gas in Texas these days?” I explained my situation, and he said, “I’m from Texas originally and I can tell by your accent that you ain’t. What’re ya doing in this godforsaken country?”

In Wyoming, I stayed less than a mile from the Heart Mountain Relocation Center, a WWII Japanese American confinement site. From 1942 to 1945, this concentration camp held almost 14,000 people, making it the third-largest town in Wyoming at the time. The majority were American citizens and had done nothing wrong and committed no crimes…they were put there for being of Japanese heritage. I regret that my plans didn’t allow for a visit; if I’d had known beforehand that it was going to be so close, I would have made the time, given our present administration’s treatment of its Muslim citizens and asylum seekers from Central and South America. As Faulkner said, “The past is never dead. It’s not even past.”

I saw some cool thunderstorms:

If I had a time machine, I would tell myself from two weeks ago to skip Mt Rushmore, Wind Cave, and the volcanic stuff in Yellowstone. And perhaps Wall Drug. I also would have opted to fly out of Salt Lake City instead of Portland, OR to give me more time to explore Montana and Wyoming…the trip ended up having too much driving and not enough being out in nature.

You can see more photos from my trip on Instagram and in this saved Instagram Story. I feel very lucky to have had the time and resources to take this trip. It definitely took me out of my comfort zone in both good ways and bad — the journey definitely wasn’t all sunshine and lollipops, despite what my photos might indicate. To many of us, it seems like a perilous time in our nation’s history, with many debts, old and new, coming due in rapid-fire succession. Doing this roadtrip reminded me of many great things about this country & the people who live in it and gave me the time & space to ponder how I fit into the puzzle, without the din of the news and social media. If you can manage it, I encourage you all to do the same, even if it’s just visiting someplace close that you’ve never been to: get out there and see the world and visit with its people. This world is all we have, and the more we see of it, the better we can make it.

I just did a two week cross country road trip from SF to Boston taking the great northern highway most of the way from Glacier N.P. to Cleveland.

I love having the overland experience of knowing how far everything is in this country.

I’ll be doing this in a month and I haven’t been so excited for a trip since I was a wee brat going to Disney World. How things change for the better!

I love driving / motorcycle trips. I’ve done trips as long as 14 days. I’ll also recommend just getting out and doing a night or two. Just get out — go somewhere new or go somewhere you’ve been, with an open mind to experiencing it in new ways. The luxury of burning dead dinosaurs allows us to see and experience so much so easily.

Do You Still RSS?

Do You Still RSS? News Reader

The fifth anniversary of the passing of Google Reader went largely unremarked in most circles, but there was some coverage on Techdirt and other sites (Wired even called for a revival of RSS).

RSS largely died with Google Reader; development of the RSS standard (and the Atom standard that replaced it) had petered out years before, and aside from a brief surge in new apps in 2013, we haven't seen a new feed reader service in years.

Nevertheless, a lot of us still use RSS on a regular basis, and I was wondering just how many people are still using RSS as much as they did 5 years ago.

I'll go first.

I am still using BazQux Reader, the app I switched to from Google Reader 5 years ago (in fact, I had to pay the annual subscription on 2 July). I still have over two thousand RSS feeds in Bazqux, but they are not half as useful as they used to be.

I checked with Feedly* and discovered 843 of the feeds I follow are now dead because either the site went away or moved its RSS feed in an update, and another 621 feeds are inactive  (new posts are only published a few times a year).

All of those feeds used to be alive with at least weekly updates, but in the past five years most of their owners have moved from owning their own platform to being, as Mike Masnick pointed out, trapped in one or another social media silo (Facebook, Twitter, etc).

How about you? Do you still RSS?

* If you use Feedly, you can check how many dead feeds you follow by opening the "organize" menu.

Batman’s Wedding

2 Comments

Batman (2016-) 050-024.jpg

Wonder Woman aside, DC’s recent movies haven’t been very good, but their recent comics have been extraordinary. In particular, writer Tom King has two contemporary masterpieces running side by side, the accessible-but-oh-so-intelligent Batman and the experimental/psychological war-and-family comic Mister Miracle.

Batman has been building beautifully towards Batman’s wedding to Catwoman, culminating in this week’s 50th issue. The ending was spoiled three days early in an article in the New York Times’ Vows column — Abraham Riesman has an interview at Vulture with the author, who regrets the spoilage — but the comic holds up beautifully, even if you know how it ends.

It’s filled with gorgeous artwork from artists who’ve played a key part in Batman and Catwoman’s history together, and each page acts as a kind of counterpoint to the one opposite it. (Writers and other important figures from the Batman mythos get their head nods elsewhere, as names of buildings, streets, and rooms in Wayne Manor.) And it has its share of moving moments, like this quiet embrace between Bruce Wayne and Alfred.

The real thrill is probably in the run-up, which you can read in trade paperbacks now. My favorite issue might be number 36, where Superman and Batman separately explain to Lois Lane and Catwoman, respectively, what they admire about each other. I mean, this is just superhero nerd gold.

This is all to say: despite some blockbuster fatigue, I think we’re still quite far from exhausting superheroes as a concept. Every time I think we’re there, someone comes up with rich, thoughtful, emotionally moving stories that bring me right back again.

I bought a couple of Tom King trades this past weekend. Mostly because of how effing cool he is on twitter, and knowing this was coming. I guess I should call the shop and order the rest of them.
