The Daily Parker

I may come back to these again:

• Sullivan on America's dynasties, and how they're bad for us.
• One of the better blog comments I've read: Codethulu. (The article commented on is also a good read.)
• Gulliver wonders whether a new sensing technology could end the ban on liquids aboard airplanes.
• Elsewhere at the Economist, a writer speculates on the reductio ad absurdam of Putin's language doctrine.

Publishing the Inner Drive Extensible Architecture™ to NuGet is still coming up...just not this weekend.

I almost forgot, even though Illinois Climatologist Jim Angel blogged it earlier today. The new NCA is here. Highlights—with a distinctly Illinois-centered view—via Angel:

• In the next few decades, longer growing seasons and rising carbon dioxide levels will increase yields of some crops, though those benefits will be progressively offset by extreme weather events. Though adaptation options can reduce some of the detrimental effects, in the long term, the combined stresses associated with climate change are expected to decrease agricultural productivity.
• Increased heat wave intensity and frequency, increased humidity, degraded air quality, and reduced water quality will increase public health risks.
• Climate change will exacerbate a range of risks to the Great Lakes, including changes in the range and distribution of certain fish species, increased invasive species and harmful blooms of algae, and declining beach health. Ice cover declines will lengthen the commercial navigation season [this winter was the exception to the rule - Jim].

If you don't mind using 170 megabytes of bandwidth, you can download the whole thing (or just the parts you want).

I debated this question with someone at a dinner a couple weeks ago. She suggested higher megapixel numbers told you more about the ego of the camera buyer than about the quality of the images.

I said it depends on how you're using the photos, but generally, more data yields more useful photos.

Here's an illustration, using a vaguely-recognizable landmark that I happened to pass earlier this weekend, and just happened to have photographed with three different cameras. All three photos are from approximately the same location at approximately the same time of day. Obviously there are some differences, but the illustration should work regardless.

Let's take a look at three images stored as 600x900 JPEGs and displayed at 500x750, the standard size for this blog. First, let's see one from a Kodak DC4800 in February 2001, 13 years ago. The original size was 1440x2160 at 3MP:

Now skip forward to August 2009, using a Canon 20D shooting a 2336x3648 JPEG at 8 MP:

Finally, two days ago, using a Canon 7D shooting raw at 3456x5184 (18 MP):

The photos look pretty comparable at this resolution, don't they? So let's zoom in on a 150x150 pixel view of each:

So each one has successively more data than the previous, which becomes obvious when you zoom in.

Another difference: I shot the one from this weekend using the raw format, which preserves all of the information the camera had available at the time of the photo. JPEG images are lossy; they always leave some information out. And because raw images are easier to manipulate using software, I was able to make the third photo a little bit better than I could make the other two.

So are more megapixels more useful? Not if you're just putting up blog posts, but for serious photography, absolutely.

I'm David Braverman, this is my blog, and Parker is my 7½-year-old mutt. I last updated this About... page in September 2011, more than 1,300 posts back, so it's time for a refresh.

The Daily Parker is about:

• Parker, my dog, whom I adopted on 1 September 2006.
• Politics. I'm a moderate-lefty by international standards, which makes me a radical left-winger in today's United States.
• The weather. I've operated a weather website for more than 13 years. That site deals with raw data and objective observations. Many weather posts also touch politics, given the political implications of addressing climate change, though happily we no longer have to do so under a president beholden to the oil industry.
• Chicago (the greatest city in North America), and sometimes London, San Francisco, and the rest of the world.
• Photography. I took tens of thousands of photos as a kid, then drifted away from making art until early 2011 when I finally got the first digital camera I've ever had whose photos were as good as film. That got me reading more, practicing more, and throwing more photos on the blog. In my initial burst of enthusiasm I posted a photo every day. I've pulled back from that a bit—it takes about 30 minutes to prep and post one of those puppies—but I'm still shooting and still learning.

I also write a lot of software, and will occasionally post about technology as well. I work for 10th Magnitude, a startup software consultancy in Chicago, I've got more than 20 years experience writing the stuff, and I continue to own a micro-sized software company. (I have an online resume, if you're curious.) I see a lot of code, and since I often get called in to projects in crisis, I see a lot of bad code, some of which may appear here.

I strive to write about these and other things with fluency and concision. "Fast, good, cheap: pick two" applies to writing as much as to any other creative process (cf: software). I hope to find an appropriate balance between the three, as streams of consciousness and literacy have always struggled against each other since the first blog twenty years ago.

If you like what you see here, you'll probably also like Andrew Sullivan, James Fallows, Josh Marshall, and Bruce Schneier. Even if you don't like my politics, you probably agree that everyone ought to read Strunk and White, and you probably have an opinion about the Oxford comma—punctuation de rigeur in my opinion.

Thanks for reading, and I hope you continue to enjoy The Daily Parker.

The Great Lakes have more ice cover than at any point in the last 20 years. Here's the view on the flight in last Monday morning:

If you don't mind a 150 MB download, NASA took a photo of the Great Lakes (and, incidentially, me) at almost that exact moment. The ice today (also 150 MB) looks about the same.

I got gas today, which isn't that interesting in itself, except that it's only the third time I've gotten gas in the past four months. Like the last time, I decided to fill up in case it got cold (a full tank is better for your car in winter), so really I've only gotten about 2½ tanks of gas since the beginning of November.

It's perfectly valid to wonder why I even own a car. I didn't for most of the time I lived in New York. Still, today I had about a half-dozen errands to run, and having a car made a huge difference, especially to Parker. If I only used Zipcar, for example, I wouldn't be able to bring him around either.

Still, this is why I like living in a big city.

When I last visited St. Martin five years ago, I struggled a bit to get through the heavily-defended border between the French and Dutch sides. I am happy to report that the two countries have made significant improvements to the border since then. For starters, they've put up a brand-new sign:

Unfortunately, it appears that an aggressor nation has taken over part of the French side:

All right, I'm wasting time writing a blog post when I could do it with something else. If only this Internet connection were faster, I could be offline a lot faster.

This is why I love Sint Maarten:

It turned out that I had an actual task today. Two, in fact. Both were pure stupidity on my part. And both completely scotched my goal of doing nothing worthwhile for four days.

First, I had promised something to my team at work before I left, but didn't realize until I checked email this morning that, well, the task was not completed. (Notice the subtle use of passive voice there.) So I had that task, which took half an hour.

Second, mentioned forgetting a few vital items in my luggage, so I had to buy them. And I paid a stupidity tax. The cost of one hat, two pairs of shorts, one pair of sandals (which I didn't already own and therefore had planned to buy here anyway), and one bottle of sunscreen was two hundred bloody dollars. In other words, I paid a 100% tax on bad packing.

So to compensate for having to do things today, after accomplishing both tasks I put on my new shorts, sunscreen, and sandals, then walked the 800 meters from my hotel to the opposite side of Maho Beach and watched planes land for three hours. I need to point out that along the way, I walked through the Caribbean Sea. My new shorts got seawater on them. I think this is exactly what they're for. Especially since the seawater was about the same temperature as the air (27°C), and unlike walking through Lake Michigan on any day except that one day in the beginning of September when everything lines up perfectly, it felt really good. (My feet are, in fact, still wet.)

I also met a few good people, had a few good drinks, and learned that the best airplane landing of the week occurs tomorrow around lunchtime when KLM flight 785 lands. It's a 747-400, the largest plane that flies here. If I have to stand out in the rain, I'm going to see this thing land.

Of course, this means I now have a plan. Even though I came to this island with the explicit goal of not accomplishing or planning anything, except maybe reading a book or two, I just can't help myself. The Dude is onto something...I just can't get there yet...

My plan is:

• Tomorrow: sleep late, eat something, walk across Maho Beach, take photos of the 747 landing, walk back to my hotel, change my shoes, walk somewhere else (possibly Marigot or Phillipsburg), have some drinks.
• Saturday: sleep late, walk somewhere (maybe even take a bus and then walk), read something, walk somewhere else, read some more, have some drinks.
• Sunday: sleep late, shove things into my suitcase, walk somewhere, retrieve my suitcase, go to New York, have some drinks.

Understand that "have some drinks" is an ongoing activity. And the happy accident is that the room I got for cheap through Bookings.com includes free drinks.

Someday, and that day may never come, I will do nothing for an entire week. Meanwhile, this is the least I can do right now. Baby steps.

Via the IANA Time Zone Database mailing list, through Randy Olson, comes this map showing the difference between local solar time and what wall clocks show throughout the world:

At the time I’m writing, near the winter solstice, Madrid’s sunset is around 17:55, more than an hour later than the sunset in, for example, Naples, which is at a similar latitude. The same difference holds at the summer solstice and around the year. Just because it applies to most places I’ve been, a time like that in Naples feels more natural to me, and probably to most non-Spanish people. But is it?

Looking for other regions of the world having the same peculiarity of Spain, I edited a world map from Wikipedia to show the difference between solar and standard time. It turns out, there are many places where the sun rises and sets late in the day, like in Spain, but not a lot where it is very early (highlighted in red and green in the map, respectively). Most of Russia is heavily red, but mostly in zones with very scarce population; the exception is St. Petersburg, with a discrepancy of two hours, but the effect on time is mitigated by the high latitude. The most extreme example of Spain-like time is western China: the difference reaches three hours against solar time. For example, today the sun rises there at 10:15 and sets at 19:45, and solar noon is at 15:01.

If you live in the green areas of the map, the sun tends to rise and set earlier than in the red zones. Not coincidentally, the places that set time policy tend to be neutral: London, Washington, Sydney, Beijing, Ottawa...they're all nearly dead-center in their respective zones. The notable exception is Moscow, where time policy goes back and forth and may even change once more this year.

Finally, a commenter on the Reddit MapPorn post where this also appeared points out: "Fun fact: The small Afghan-Chinese border is the largest jump in timezone in the world. (3 and a half hour difference on each side) You'd get jet lag crossing that border."
