If a bad person believes something, it must be false!

I learned something new today:

The Unabomber believes in global warming. Therefore, since the Unabomber is a bad person, the theory of global warming must be false.

Lots of other fun facts follow from this line of reasoning. For example, did you know that God does not exist? After all, Hitler believed in God.

Also, God does exist, because Stalin did not believe in God.

Mussolini supported the idea of capitalism, so capitalism is a bankrupt philosophy.

It is a known fact that mass-murderer Jeffrey Dahmer believed that birds could fly. Therefore, birds cannot fly.

Also, reason is dead, because even stupid people can see that the logic in the Heartland Institute’s billboard is woefully flawed.

Word Munger 8 years in: What’s the use of blogging?

Well, that went by fast. Today Word Munger turns eight. Eight years ago, blogging was still a relatively new thing. I had had a livejournal blog before that, and a static web page with regular updates before that, but Word Munger was my first fully-functional blog in the modern sense (although it’s interesting to note that Facebook is probably more like LiveJournal than WordPress). Word Munger also happens to be the blog that I’ve maintained (more or less fastidiously) since the beginning.

But over the years, Word Munger has slowed down. Facebook and Twitter seem more alluring, offering more instant feedback from readers. I’ve started a new business, and I’m actively involved in a major web project. Oh yeah, and I’ve become obsessed with running.

Sometimes I wonder whether there’s any point in maintaining Word Munger any more. Today before I wrote this post I went through and deleted some spam comments, and accidentally took out a couple legitimate ones. I didn’t feel any compunction to try and undo my act of negligence. Recent posts on WordMunger have gotten one, two comments at the most. I can get dozens of comments from a one-off on Twitter or Facebook.

Still, a blog is a great place to offer more-extended discussion than is possible through the normal social media channels. A running blog I contribute to has actually disabled comments; we keep the blog going, but we expect any commenting that occurs to happen on Facebook. I’ve thought about doing that here, but I like have the comments associated with the blog post itself (curator error aside).

I will probably keep WordMunger going for the foreseeable future. I need to keep a webhost for other reasons, and I never know when I will want to write up something for general consumption. I can’t guarantee I’ll post often. When I do, you’ll probably hear about it — on Facebook or Twitter, that is.

Why “What if I’d never been born?” doesn’t wash, and why no one will be persuaded by this argument

sciseekclaimtoken-4f7059467bc85

Over on Slate, a debate is raging about whether the “What if I’d never been born?” argument is a valid line of reasoning in the abortion debate.

I understand the argument: I value my life, and if my Mom had had an abortion back in 1967, I would never have existed. This is a bad thing, therefore abortion is bad and should be outlawed.

Here’s the problem with the argument: I could equally argue the following: “I value my life, and if my Mom had not been a Catholic, she would have had an abortion. Therefore all women should be forcibly converted to Catholicism.”

Or “I value my life, and if my Mom and Dad hadn’t started dating in 1965, I would never have been conceived, therefore all women should be forced to date my Dad.” Or something.

The case for abortion does not hinge on whether a given person, living today, should have been denied the right to be born X years ago. Indeed, it is not about whether it is ever appropriate to have laws that could lead to human deaths.

Otherwise what would the justification for war be — if all human life is sacred, then should we ever sanction something that might result in a loss of life? Shouldn’t we refuse to engage in any military conflict, regardless of its potential merits? Wouldn’t there be a moral imperative to provide free health care for all? Shouldn’t we ban motorcycles, and firearms, and any object that might become lodged in some unsuspecting toddler’s throat? Shouldn’t the universal speed limit be set at 5 miles per hour? Once we acknowledge that it is acceptable to have a policy that will result in a loss of human life, then we are living in a world of relativism, not a world of absolutes.

At this point it becomes reasonable to weigh the harm of forcing a woman to bear an unwanted pregnancy against the harm of aborting a fetus or embryo. Heart-wrenching as it may be for the woman making the choice, it’s not a difficult decision as a matter of policy. The woman is a grown person, with friends, family, loved ones, and the capacity to love and think. The fetus is not. Pregnancy and childbirth is dangerous, even sometimes life-threatening. The fetus, which might technically be termed “living” and “human,” has less cognitive capacity than a rodent, which most humans would have no qualms about killing (or perhaps hiring someone else to kill) if it was encroaching on their lives in even the most benign way. Clearly it’s acceptable to kill a being like a rodent in order to spare a woman 9 months of illness and discomfort and even distortion of her body, followed by ten to twenty-four hours or more of appalling pain that under any other circumstance would be considered gruesome torture, followed by weeks of recovery and often permanent disfigurement.

If the anti-abortion forces weren’t so dogmatic, I would even be willing to accept a compromise, setting some point in a pregnancy where abortions were illegal, perhaps after 4 months or so, in exchange for removing all restrictions on abortion prior to that point and ensuring it was available to all women.

But clearly this isn’t the sort of foe pro-choicers face. Larimore, who makes every effort to appear reasonable, clearly wouldn’t accept such a compromise. While she seems to acknowledge the point that 90 percent of abortions take place before the 12th week, when the embryo is anything but human-like, she later dismisses it, saying “it’s barbaric to kill 1 million babies a year.” Remember, we’re talking about a thumbnail-sized blob that in Larimore’s words looks more like a “space alien” than a human.

And of course Larimore completely leaves women out of her “barbarity” equation. Is it not barbaric to torture and disfigure 1 million women a year by forcing them to undergo pregnancy and childbirth?

But as I’ve said, this argument won’t convince anyone, because anti-choicers have already taken Larimore’s logical leap from embryo to fetus to baby. My comparison of an fetus to a “rodent” would strike them as offensive, because they believe a fetus, an embryo, even a zygote is a baby, and babies are wonderful!

But pro-lifers might argue “What is the difference between a baby and a fetus? Isn’t the fetus just a baby that hasn’t been born yet?” In some senses, yes, but once the baby is born, then killing it doesn’t save the mother from pregnancy and childbirth. There is no justification for killing the baby because its existence doesn’t depend on the physical pain and disfigurement of a woman.

Pro-lifers then counter with their trump card: The woman deserves to be pregnant because she chose to have sex.

To which I respond: Is that all you got? Why aren’t you banning sex, then? If sex (or sex out of wedlock, or sex without the intention of producing kids, or whatever the hell you think is “sinful”) is what really bothers you, then why not try to stop that? Good luck at it.

More pics from Colorado

Last June, the family took a trip to Colorado so I could run the Steamboat Marathon. Somehow I didn’t get around to chronicling the trip until now.

Before we went to Steamboat, we thought we’d visit Rocky Mountain National Park. I had never been there, so it was a great chance to see a new place. Plus, we’d be able to drive through the park and take an interesting route to Steamboat, where we needed to be that evening.

When we arrived at the park, we found out that the road through the park was closed! We’d have to take a three-hour detour to get to Steamboat, returning almost the same way we had come. Oops!

But we still had time for a short hike, and fortunately Nora took pictures, because for some reason Greta and I didn’t take many.

Rocky Mountain NP is beautiful in the spring, but there’s too much snow at the higher elevations for a casual day hike. Fortunately we were able to find a route with just a couple of patches here and there. Much of the time we were strolling through glades of aspen, like this:

But we also got to walk through open meadows, with the taller, snow-capped peaks looming above:

We stopped for lunch at a lake, where one of the local waterfowl was not at all shy about begging for food:

Across the valley was a spectacular waterfall:

Nora spent some time trying to capture the motion of the small springs at the side of the trail. I think she did a particularly good job with this photo.

Then we descended to a raging creek. Colorado had had tons of snow this past year, and now it was all melting. Indeed, many of the rivers we would see later were above flood stage. I don’t think this creek typically had this much water:

If you have QuickTime installed on your computer, you can click on the picture to watch a short movie I made showing just how much water was flowing through this small gorge.

We hiked a little farther than we had planned, and it was getting late, so I ended up running to the car and driving a mile back up the road to pick Greta and Nora up. When we finally got to Steamboat, it was past 10 pm. A long day, but also a beautiful one!

Belated, abbreviated vacationblogging: Coyote Gulch

Way back in June, after my spectacular collapse at the Steamboat Marathon, Greta, Nora and I embarked on a series of day hikes that are way too cool not to chronicle here. However, in the interest of getting this done, I’m going to be fairly brief and mainly let the photos speak for themselves.

First up is our fourth hike, because I’m waiting on some pictures of the other hikes from Nora and Greta. At this point, Nora and I had dropped Greta off in Denver so we could do some “more extreme” hiking in Utah.

The first hike was based out of Escalante, a tiny town that’s off the beaten path of major national parks in Utah — Zion, Bryce, Arches, Canyonland — but in an area that’s no less spectacular. After a drive down a knife-edge ridge to get to the town, we checked in to a local motel, and awoke at the crack of dawn for our hike.

Even getting to the trailhead was a bit of an adventure, involving 45 miles on a gravel road, through a herd of cattle (driven by genuine cowboys riding genuine horses and shouting genuine cowboy orders to the cows, like “hyah” and “git along”).

The hike was supposed to be a 11-mile loop involving two cars parked at two separate trailheads, but since we only had one car, we stopped at the second trailhead (where we’d be exiting) and started to walk 2 miles down the road to the first trailhead. Amazingly, within about a minute a truck driven by a very friendly scoutmaster came by and offered us a ride to the first trailhead. After a hilarious incident involving Mormon crickets (which will have to wait told some other time), we were dropped off and started on our way. At first we were walking along the open desert, which was beautiful in itself:

Then we hit the side of Escalante Canyon, and it wasn’t immediately apparent how to get down. Fortunately our guidebook showed us how to do it — it involved descending a crack that was just wide enough for me to squeeze through, after removing my backpack. Here’s Nora scaling the entry:

And here’s a picture that shows how close to the edge of the canyon this gap is:

After plunging down to the bottom of the canyon and wading around a bit in the Escalante, we began our hike back up Coyote Gulch. There was a little creek running through the whole gulch, and most of the time, the easiest hiking was just walking in the water.

All along the way were fantastic rock formations:

As we wound our way up the canyon, we saw three separate arches, which were cool, but not quite as photogenic as the ones in Arches National Park.

It was a hot day, but because the gulch was so narrow, we were usually able to find some shade along the way.

Finally we reached the point where our guidebook said we’d be able to clamber out of the canyon. The book suggested bringing a rope for hauling up your backpacks, but I was hoping that since I just had a small day-pack, I’d be fine. There were a couple hairy moments, but we ended up making it out without incident. Here’s a shot of Nora making her way up the final stretch of the climb.

I tracked our entire route using GPS — not so much because I thought it would help us navigate, but just to get a sense of where we had gone. Indeed, the satellite view of the route is pretty neat:

Here’s the entire GPS record of the hike.

Boogie Boarding: South Carolina versus Hawaii

South Carolina: You spend most of your time looking for a wave big enough to ride.
Hawaii: You spend most of your time looking for a wave that won’t kill you.

South Carolina: After a couple hours at it, you’re ready to stare down the newbs
Hawaii: Unless you were born here, you are a newb.

South Carolina: After 45 minutes, you still haven’t managed to find a decent wave
Hawaii: After 45 minutes, 5 or 6 “perfect waves” in a row nearly break you in half, and you’re ready to call it a day.

Marketing Moab

June 11, 2011. I’m here in Moab, Utah, enjoying some quality adventure travel with my daughter Nora, who’s the only member of the family other than me who’s even remotely interested in anything with “adventure” in its description.

We spent the afternoon touring one of our nation’s best-loved monuments, Arches National Park. But as we encountered arch after spectacular arch, it occurred to us that the National Park Service is probably underselling Arches. Who wants to travel thousands of miles and endure stifling heat to see something called “Delicate Arch”? Sure, it’s so beautiful that Utah put it on its license plate, but that makes it even more critical to market the arch in a way that makes folks actually want to visit–after all, you see the arch on the plates every day.

We’ve decided to rename the most prominent monuments in Arches in ways that should attract more visitors.

One of the first things visitors see as they enter the park is a spectacular wall with unique stone formations. The official map of Arches calls it The Great Wall, but China’s already got one of those, am I right? What China doesn’t have is something called The Blobular Wall, which also happens to be a more accurate description of what the wall looks like:

In a short while, visitors drive by Rock Chimneys. Since nearly every park in the known universe has a “chimney rock,” this isn’t exactly playing to Arches’ strengths. Again, we think Blobby Chimneys is a name that reflects the true uniqueness of these formations.

A mile or so up the road is another incredible formation with the devastatingly boring moniker of Balanced Rock. We’ve renamed it The Precarious Orb, a much better way to describe its haunting, otherwordly presence.

Next visitors arrive at a viewing area surrounded by more than eight different arches. We’ve renamed the Windows in a way that’s much more descriptive and enticing: The Eyebrows.

Similarly, Turret Arch is named after a word which few potential visitors will recognize. We’ve gone with a name that’s part of four of the highest-grossing motion pictures in history: Pirate Arch.

Across the way from these arches is one of the most famous and most boringly-named formations in the entire park: Double Arch. These arches are so massive that it’s almost hard to mentally process. And even if one of them fell down (as is likely to occur eventually due to natural forces), there’s another, equally grand one ready to take its place. Thus, we’ve renamed them Epic Arch and Insurance Arch.

A few miles down the main road in Arches takes you to Devil’s Gardens. A few decades ago, this might have titillated a few park visitors, but nowadays the Devil rarely strikes fear in anyone. Yet there is one person in America that strikes fear in the heart of nearly everyone who visits him/her: The Dentist. Combine that with the fact that these formations look like really bad teeth, and it’ll be clear why we renamed them The Dentist’s Delight.

Hike about a mile up the trail through The Dentist’s Delight, and you’ll arrive at the largest arch in the park, though you wouldn’t know it from it’s yawn-inducing name, Landscape Arch. In 1991, tons of rock fell from the arch to the valley floor, illustrating that all the arches in the park are indeed precarious. But what sells better than death? Van Gogh couldn’t make a dime off his work, but now his paintings are priceless. Thus, we renamed it Dying Arch. Who won’t want to see this arch before it’s gone forever?

The name of the crowning glory of Arches National Park, Delicate Arch, practically begs us to ignore it. Sure, the arch does appear to be delicate, its fragile form precariously perched over the edge of an immense cliff, but that doesn’t mean we can’t sell the darned thing a bit better. Henceforth, it should be known as The Rootin’ Tootin’ Humongo Arch. Add Johnny Depp and Penelope Cruz, and who wouldn’t want to go see that?

I went to a marathon and all I brought back was this blog post

I don’t usually discuss my running exploits here on Word Munger, but I figure that running my first-ever marathon is a Word-Munger-worthy event, so follow the link and enjoy.

Race Report: The Big Sur International Marathon

Happy anniversary, Word Munger!

Today Word Munger turns seven! That’s right, I’ve been filling this space with my musings for seven full years—or even longer if you count the original Word Munger, a hand-coded satire site I started wayyyy back in the year 2000. Here’s the first post there, about how some people simply can’t get over the 2000 Bush/Gore election debacle. I think I still get some of those jokes…

Word Munger has had a complicated history. Some years, I posted nearly every day. But over the years, I’ve also found other online venues — most notably, Cognitive Daily, which ran for five years. Between that and my duties at Research Blogging, my productivity here at Word Munger has waned recently. Looking now at the “recent posts” in the sidebar, I see that I’ve only posted 10 times since last September.

That’s partially due to my job, but perhaps more because I’m now training to run my first (and possibly my last) marathon. I’ve found marathon training to be so consuming that I wanted to write about every last training run. I decided not to bore my non-running readers with that, so I started up a separate blog, Mungerruns, for all things running. After I’ve completed the Big Sur Marathon less than two weeks from now, it’s possible that I’ll back off the marathonblogging and start blogging here more often. My running friends don’t seem to think that’s likely, though — they say that once you’ve run your first marathon, you’re hooked for life. I kind of hope that’s not true, because all that running sure takes a lot of time.

During the last year I’ve also worked on two other projects, ScienceSeeker and a monthly column at 3 Quarks Daily. ScienceSeeker is sort of a faster-paced version of Research Blogging, covering more dimensions of science, from lab life to politics to gender issues. The 3 Quarks column tries to understand contemporary political issues from the perspective of my stepbrother, a disabled artist who struggles to live on a $600 monthly Social Security check (they don’t yet have an archive so today I created a page with links to all my columns).

In the past year I’ve also sent my oldest child to college, and my youngest has been admitted to college, so I imagine that even bigger changes are in store over the next year as Greta and I begin life as “empty nesters” (that said, at this point it looks like being an empty-nester starts off with two bored young adults living with you all summer).

I can’t promise that I’ll be posting here more frequently over the next year, but I can promise that I’ll maintain the site for at least another year (at this point I plan on maintaining the site indefinitely), so I’d recommend you keep on coming back at least every month or so to see what’s on my mind. For more regular updates, friend me on Facebook or follow me on Twitter.

What didn’t Watson the computer do?

I don’t pretend to know much more about computers than Stanley Fish does. But I do know a little bit more, and that little bit is the crucial bit.

Yesterday, Fish wrote a column in the New York Times belittling IBM’s achievement in developing a computer that can beat the best human contestants on Jeopardy. Fish compared Watson to an automated word-completion algorithm on his computer that is incorrect with frustrating frequency. Watson, Fish claims, isn’t any better.

Except that Watson is better. Unlike Fish’s program, Watson gets its answers right nearly all the time. Fish is unimpressed:

it has no holistic sense of context and no ability to to survey possibilities from a contextual perspective; it doesn’t begin with what Wittgenstein terms a “form of life,” but must build up a form of life, a world, from the only thing it has and is, “bits of context-free, completely determinate data.” And since the data, no matter how large in quantity, can never add up to a context and will always remain discrete bits, the world can never be built.

I’m sure Fish knows much more about Wittgenstein than I do, but I dispute this notion that there is some “form of life” that only humans, and never computers, can comprehend. Fish asserts that the computer has no “context,” but if Fish had seen the Nova documentary on Watson, he would have seen some impressive demonstrations of Watson seeming to build an understanding of context on the fly. In one case, Watson appeared to “learn” that all the responses in a particular category were names of months, missing its first answer, but seeing the error of its ways after the human contestants began to get correct “month” responses. How is this different from how humans learn about context?

In attempting to diminish IBM’s achievement with Watson, Fish quotes from a 39-year-old critique of artificial intelligence: A computer can’t adapt, Fish claims, and can “at best be programmed to try out a series of hypotheses to see which best fit the fixed data.” But this isn’t the way Watson is “programmed” at all. In fact, Watson was trained using machine learning, a technique that didn’t exist in the 1970s when Dreyfus wrote his screed against AI. Humans didn’t give Watson a set of rules, they gave it a procedure by which to develop its own rules. Then they fed it immense quantities of information, correcting it when it responded incorrectly, so that it could adapt its rules to the new information.

Here’s Fish’s understanding of what Watson is doing: “It decomposes the question put to it into discrete bits of data and then searches its vast data base for statistically frequent combinations of the bits it is working with.” Perhaps Watson is doing that, but clearly Watson is doing much more than that as well. Decomposes how? What does it do once it finds those combinations of bits? How does Watson decide which bits are most relevant? Fish doesn’t know, and in many ways, Watson’s programmers don’t know either. That’s what machine learning is, and machine learning is only going to get more powerful in the future. We teach machines how to create their own rules, then they learn things using that system.

They’re not as good as humans in many fields, but they’re already better than humans in some, like Jeopardy and chess. Maybe computers will never catch up to humans in some fields like art and poetry. But for most things that most of us do every day? Given enough time — say, 100 years — I wouldn’t bet against the computers.

Update: After thinking about this a bit, I have to say unless historical events end up massively impeding technological progress, that 100-year bet is way too conservative. Computers have only been around for about 70 years, so 100 years is like an eternity. I wouldn’t be surprised to see this come to pass in as little as 30 years. That isn’t to say humans wouldn’t be needed at that point; just that our relationship with computers will be very different from what it is now. We will start to interact with them more like we do with other people. We won’t think “how can I get this computer to do what I want?” We’ll think, “how can I work together with the computer to get the job done?”

An imagined conversation with Netflix

Wii User: Hello, Netflix? I’d like to view interweb movies on my Wii console, just like it says I can on the ad in my latest Netflix DVD.

Netflix Customer Support Rep: You’re all set. Your Wii is ready to go.

WU: But I need to start up a subscription with you guys.

NCSR: No you don’t. It’s included in your subscription rate.

WU: But my Wii can’t connect to the interwebs.

NCSR: All Wii consoles connect to the intenet.

WU: They do? How?

NCSR: Why don’t you check out Nintendo’s support page at Support.nintendo.com. It explains everything.

WU: Can’t you explain how?

NCSR: That’s really not my job. The Wii is a Nintendo product.

WU: Do I have to pay extra for that?

NCSR: Not unless you don’t already have internet service at your home. Which I assume you do, since you can only order Netflix DVDs via the internet.

WU: That sounds pretty complicated. Why does the ad make it look so easy?

I think it must have been conversations like this that led to the ad I received today with my latest DVD from Netflix:

Basically the ad is a tech support call! The fine print reads “Broadband internet access required. For more info on connecting your Wii to the internet, go to support.nintendo.com. Wii is a trademark of Nintendo.”

My guess is, earlier versions of the ad just said something like “Now get Netflix videos on your Wii!” and then Netflix got deluged with support requests just like the one I imagined above.

Top Ten Reasons I Hate Top-Ten Lists

10. Ten? Why ten? Don’t some topics merit, say a top-20 list? Or on the other hand, sometimes there are only a few deserving items, so the list ends up getting padded with pointless choices.

9. Like this one.

8. Top-ten lists are often served up one or two items at a time, forcing you to click through page after page of items just to see what #1 is. If it’s a list, shouldn’t it be displayed in, you know, list format?

7. Top ten-lists often give no justification at all for the selections, or for the order of the selections.

6. Top-ten lists are often not even credited with an author, so you have no idea who to blame for the choices.

5. When there is an author, he or she often feels obligated to pick a few items you’ve never heard of, just to show off. If you’re listing the “Top 10 Movies of 2010,” don’t include three French documentaries you saw in SoHo and were never released outside of Manhattan.

4. Authors like to be controversial, so they also always list some “underappreciated” item like Gigli or Death Rampage 2007: The BloodPocalypse. Bad idea. They’re underappreciated for a reason.

3. Often top-ten lists are just linkbait. Why else would a site called “online psychology degrees” have a list of the top ten psychology blogs (or even better, the top 100)? Because then unsuspecting bloggers link back to the post (“Goody! I’m the #57 psychology blog according to this spammer I’ve never heard of”), which in turn gives the site a higher Google PageRank, so the next time some unsatisfied hairdresser contemplates a career change, she’ll be directed to the spam site instead of someplace where the proprietors are actually concerned about the quality of information they provide.

2. Gigli

1. You see now, here I am at #1, and you’d think I’d have something really relevant to say. But whatever it is, you’ll probably disagree. Which is the entire point of top-ten lists. Everyone loves to disagree with them. They’re absolutely ruthless psychological tricks. And they work. Which means, despite the fact that I hate them, I’ll probably click on the next link to one I see.

(Shameless linkbait: Thanks, Brian Romans, for suggesting I write this post)

Some reflections on ScienceSeeker

On Saturday morning at the ScienceOnline conference in North Carolina’s Research Triangle, I was part of the team that launched ScienceSeeker, a new blog aggregator that strives to collect posts from all science blogs around the internet.

In contrast to ResearchBlogging.org, ScienceSeeker is inclusive. Whether you’re posting your trip to Maui or a detailed analysis of a journal article, it will show up on ScienceSeeker.

Won’t people who are looking for “real science” be discouraged by the site? I’d say if the site was launched two years ago, the answer would have been yes. But now with the rise of Twitter and the opening up of Facebook to a much wider audience, people are accustomed to getting a lot of noise with their signals. We list 50 posts on a page (and we may increase that number), so readers can easily scan past the posts that don’t interest them. No harm, no foul.

You can also filter (a bit crudely) by topic. So if you just want to see biology posts, you click on that topic, and you’ll see only posts from blogs listed in the “biology” topic. The problem with this is that we don’t filter on a post-by-post basis. So you’ll still see the Maui posts, political rants, and whatever else biologists like to blog about.

The reason for this is an elaborate compromise we worked out as we were developing the site. We wanted it to be usable from launch, so we pared down the feature list to those functions which were absolutely essential: Bloggers needed to be able to submit and claim blogs, and readers needed to filter by topic. There’s no search function, no way for individual users to edit their settings after they’ve submitted a blog, and no post-level tagging.

We finished the site in a whirlwind of activity during the last two weeks before launch. I was doing most of the CSS and graphic design, Mark Hahnel handled the WordPress install and found third-party plugins for some of our key functions, and Jessica Hekman and Chris Maden did the serious coding. Jessica in particular was simply amazing at pulling the site together, working an incredible number of hours, including a marathon session on Christmas day.

While the site is built on a WordPress framework, the guts of the system are all custom-coded plugins. Even the data for the individual posts on the site is handled by a separate database, not WordPress. The only thing we really use WordPress for is registration and administration, and as a frame for the visual presentation of the site.

On Saturday at launch, we got lots of positive feedback, and the site was tweeted all over the place, most notably by Bad Astronomer and his thousands of followers. By this morning, we’d had over 100 new blogs register, bringing the total of registered blogs well over 500.

But of course, there have been complaints as well—users want to edit/delete their accounts and they can’t do that. They want custom RSS subscriptions, and they can’t do that. They want their twitter account to automatically appear on the Member Tweets sidebar, and it doesn’t do that.

I was actually expecting more complaints—and I’m sure more will come, but overall, I’m quite pleased with the launch. The hardest thing about it is yet to come: Figuring out what enhancement we’ll offer next.

What it takes to lose it

As of this morning, I weighed 200 pounds. That’s the least I’ve weighed since the early 1990s. At one point in the late 90s, with the stress of running a business and two small children, I weighed as much as 250, but I’ve slowly chipped away at that over the years. By the 2000s I was pretty steadily in the 220s. For someone my height (6′ 1″), the BMI calculator says 250 counts as “obese,” while 220 is just “overweight.”

There’s no question that, at 220 pounds, I was overweight. Last April, I began blogging about fitness over at Daily Monthly. I weighed 225, right around where I’d been for the past decade. I felt like I was in okay shape, but I’ve always thought I could do a little better. This summer I decided I would train for a marathon, and the first part of the plan was to get down to a weight of 200 pounds by December 1. I’d then run the Thunder Road Half Marathon in Charlotte on December 11, and look for a good marathon to run in the spring of 2011.

By the beginning of August, I weighed about 220, and I set mini-goals of losing five pounds a month. The first ten pounds came off fairly easily as I ramped up my training for the half-marathon. I was running nearly 30 miles per week, and just eating a salad at lunch and cutting back on snacks seemed to be all I needed to do to lose weight.

But by early October, progress stalled. Even as I began to increase my mileage, I couldn’t seem to lose any more weight. I’d feel like I was starving during my runs, and despite the fact that sweets had been banished, I couldn’t resist the urge to snack on whatever I could find around the house. Some days I was so hungry I got dizzy. I missed my November 1 goal of 205 pounds, weighing in at 207 on November 2. Finally, by the 7th, I was down to 205. During November, I boosted my mileage again, to over 40 miles per week. The pounds were coming off easier, but Thanksgiving loomed ahead. On Thanksgiving morning, after a long run, I weighed in at 199. But I knew there would be temptations everywhere all weekend long. I couldn’t resist leftover pumpkin pie for breakfast, or cookies throughout the day. By November 29, even after another 10-mile run, I was back up to 202. But we were out of pie. On December 1, I still weighed 202. I ate light all day, ran 6 miles, went to Pilates class, and ran another 4.3 miles this morning. Weighing myself as I stepped out of the shower (after hydrating and eating breakfast), I was finally down to 200 pounds. Here’s a chart of my weight loss for the past 3 months:

I’m sitting here typing this post wearing jeans I could barely squeeze into last year. The only way they stay up is with a tightly-cinched belt. On cold days, my running tights sag low on my hips. I’d replace them, but I simply can’t imagine switching from a size L/XL to S/M.

Even so, I still have a bit of a gut. Remember those can you pinch an inch? TV commercials from the 70s? I can still pinch well over an inch. But at least it’s not the 3 or 4 inches of abdominal fat I used to be able to grab.

At this point, however, I’m only about halfway through my plan to run a marathon. I’ve run half-marathons before, but never a full marathon. After my half-marathon 10 days from now, I’m going to be adding on even more miles, peaking in March at 70 miles per week. I don’t plan on “dieting” during this time, but I’m going to try to keep eating healthy foods, and we’ll see what happens. Even at 200 pounds my BMI is 26.4, which counts as “overweight.” To count as “normal,” I’d have to get down to 189. I’m less concerned about that than I am about putting in enough miles while staying injury-free. I’m registered for the Big Sur Marathon on May 1.

This is not a lifestyle I will be able to maintain over the long run. I’m deliberately cutting back on my writing and other work while I train, and I may have to cut back even more in the spring. But hopefully I’ll be able to use the discipline I’ve gained during this period to keep my weight at a healthy level. I won’t stop running, and I may even do another marathon or two, but on May 1, I expect to be the fittest I ever have been, and I don’t think I’ll ever be fitter. That’s fine with me. One good marathon is plenty for a lifetime.

Race Report: Huntersville Fall Harvest 5K

At the last minute yesterday I decided I wanted to do a 5K this weekend, and the Huntersville Fall Harvest 5K fit the bill. It’s a relatively flat course, near where I live, and the weather was slated to be perfect — about 40 degrees at race time. I’m starting a new training program as I get ready to run my first-ever marathon, and when I’m doing speed work like intervals, etc., the program specifies that I should be running at 5K race pace.

Since I feel like I’ve improved a lot since my last 5K in the spring, it seemed like a good idea to run a new one. In that last race, the Bare Bones 5K in Salisbury, I ran a 23:55, which works out to about 7:42 per mile. Today I was thinking I might be able to run about as fast as 7:15 per mile. The plan was to start at that 7:15 pace, then see if I could hang on until the finish.

At the start we all crowded onto Verhoeff Dr., a two-lane rural highway that had been closed off by the local police. As we waited for the start, the last few racers from the 10K that had started an hour and a half earlier were heading to the finish, which involved them making their way through the crowd of 5K runners. Fortunately, the 5K racers were very polite, parting like the Red Sea and giving each 10K racer a hearty round of applause.

At the start, there was no bullhorn, just a guy with a gun, but that did the trick, and we were off, running through the beautiful, semi-rural course. The first mile was downhill, and a lot of folks started aggressively, including me. At the one mile marker, I felt good, and I made it in 6:57, faster than I had planned. Then the course turned uphill. If I was going to hit my target time, I needed to maintain my pace heading uphill. The hill was quite gentle, even more gradual than some of the flattest portions of my daily training run, so it really wasn’t too bad. I think I passed at least 20 runners on mile 2, which I finished in 7:14 — still on pace! All I had to do now was hang on to the end. I passed another few runners at the start of mile 3, which was still slightly uphill. I could feel myself starting to tire a bit at the end of mile 3, and a couple runners passed me. I tried to stay with them, but I wanted to make sure I didn’t kill myself and not run strong through the finish, so in the end I had to let them go. Mile 3 was finished in 7:16 — slightly off pace, but not bad. All that was left was around 2 tenths of a mile — the race website lists the race as 3.2 miles, even though a true 5K would be 3.1. I ran strong to the finish, finishing just behind the two guys who passed me in that last mile.

Unofficial finish time: 22:14. I can’t remember ever doing a 5K faster — does that make it a P.R.? That’s a pace of 7:06 per mile — even better than my target pace! Yes indeed, that is a bit of smug self-satisfaction you’re detecting just now. A great way to start the weekend!

I don’t think the official results have been posted yet; I’ll try to link to them when they are. If you’re interested, here’s the GPS record of my race.

Update: The results have been posted here. I finished 23rd out of 330 runners, and I was fourth in my age group. As it turned out, those two guys who passed me in the last mile were in my age group, so if I had managed to hold them off, I would have finished second. As it was, I was two seconds out of second place, and eight seconds out of first place in my age group.

How much does the weather affect my running?

For the past two months I’ve been running with a new toy, a GPS trainer that tracks (almost) exactly where I’ve run and how fast I ran. Lately I’ve been improving a whole lot, which has been extremely gratifying. But on this morning’s run I took a step backward, running slower than I have for weeks. What’s up with that?

Then I noticed on Facebook that several of my running acquaintances were reporting the same sluggish pace today. It was quite warm and muggy this morning. Could it be that all my “improvements” over that past month have really been due to cooler weather? Since my GPS device records every run, I thought I’d compare my Wednesday morning run pace (over about six miles) to the weather. This graph shows the results:

The blue line shows my pace in minutes per mile — so lower numbers are better. Green columns show the high temperature for that day, while gold columns show the previous day’s low, which I think comes closest to approximating the temperature at run-time, 6:00 a.m. As you can see, starting October 6, I improved dramatically, shaving almost a half-minute per mile off my pace. For a runner, this is huge! Then I continued that improvement on the 13th and the 20th, before regressing back to roughly my October 6 pace today. The pace changes don’t seem to bear much relationship to the high temps — my slowest pace was on the coolest day. But low temps tell a different story — my first dramatic improvement came on a day where the low was 19 degrees cooler than the previous week. My regression today came after a 15-degree rise from the low temp last week.

I also computed correlation coefficients for my run pace and temperature. The correlation between pace and high temp was 0.35, while the correlation between pace and low temp was a whopping 0.58!

Is this statistically significant? Nope — my N of just 8 means that p = 0.13. But it’s a fairly dramatic trend. However, since Wednesdays are the only days I run 6 miles, it would be hard to get a larger sample. Maybe I’ll reassess when things start warming up again in the spring.

Update: There have been a few requests on Twitter / Facebook to include more weather variables. I’ve heard dew point is a better proxy for humidity than “relative humidity,” so here’s a graph showing dew point instead of high temperature:

Just taking a look at the graph, dew point does not appear to explain the variance in my pace as well as low temperature. Indeed, the correlation coefficient for pace vs. dew point was 0.39 — slightly better than the high-temperature number, but not nearly as good as the low-temp correlation. And of course, like the other correlations, it’s not significant.

Meme o’ the day: How plebe are you?

I’m not feeling very inspired today, so how about a meme, courtesy of Kevin Drum. The higher you score, the more non-elitist you are.

1. Can you talk about “Mad Men?” No.
2. Can you talk about the “The Sopranos?” No.
3. Do you know who replaced Bob Barker on “The Price Is Right?” No.
4. Have you watched an Oprah show from beginning to end? I don’t think so. If I ever did it was a long time ago.
5. Can you hold forth animatedly about yoga? No.
6. How about pilates? Yes. I just started taking classes about a month ago.
7. How about skiing? Yes. Though this was not considered elitist in Seattle where I grew up.
8. Mountain biking? Yes.
9. Do you know who Jimmie Johnson is? Yes.
10. Does the acronym MMA mean anything to you? No.
11. Can you talk about books endlessly? Not really. I’m a child the internet.
12. Have you ever read a “Left Behind” novel? No.
13. How about a Harlequin romance? No.
14. Do you take interesting vacations? They’re interesting to me!
15. Do you know a great backpacking spot in the Sierra Nevada? No. I think they’re over-rated. But this probably means I should score this one as a “yes.”
16. What about an exquisite B&B overlooking Boothbay Harbor? No.
17. Would you be caught dead in an RV? Sure, why not?
18. Would you be caught dead on a cruise ship? I did go on a cruise with my grandparents back in my college days and I thought it was kind of fun.
19. Have you ever heard of of Branson, Mo? Yes.
20. Have you ever attended a meeting of a Kiwanis Club? No.
21. How about the Rotary Club? No.
22. Have you lived for at least a year in a small town? I’m not sure if Davidson, NC counts. It’s sort of suburban, but it fashions itself as a small town. But it’s a college town, so that probably only qualifies for half a point.
23. Have you lived for a year in an urban neighborhood in which most of your neighbors did not have college degrees? Yep.
24. Have you spent at least a year with a family income less than twice the poverty line? Yep. How about less than the poverty line itself?
25. Do you have a close friend who is an evangelical Christian? No, unless former evangelical Christians count.
26. Have you ever visited a factory floor? No.
27. Have you worked on one? No.

Score: 11.5 out of 27. I’m 43% plebeian. Kevin scored 63 percent. Clearly he’s got his pulse more on the heartbeat of America than I do. But as a liberal journalist who’s married to a liberal-arts professor, I suppose that’s to be expected.

One thing Mr. Murray didn’t provide with his quiz is any sort of scoring guide. What qualifies as sufficiently in touch with “real” America? 50%? 100%? Do all tea-party candidates have to pass the test? What if a liberal passes? Does she have to switch parties?

Update: There has been a twitter query about how to score this thing. I really don’t know — I scored a plebe-y answer as “1″ — but note that each question has a different “right” answer. So in my rubric, the higher your score, the more plebeian you are.

“Upgraded”

WordPress has upgraded. Why is it that every time I “upgrade,” my old theme no longer works? Now I’m using the standard, generic theme. Nothing wrong with that. But I wish there was some way to get the upgrade process to work without breaking everything that came before.

What are a journalist’s responsibilities on Twitter?

I’ve never really thought of myself as a journalist. Sure, I write a column for an online magazine, and even get paid for it. But as a columnist, my job is a little different from that of a reporter. I have a distinct point of view—I promote research blogging—which is the kind of thing reporters try to avoid. That said, I also have been a critic of those who want to draw sharp lines between “journalists” and “bloggers,” and I’d add “columnists” to that list too, so I probably ought to resign myself to the fact that, for better or worse, I am a journalist.

But sometimes I take off my journalist hat and just chat with people. Sometimes I write completely non-journalistic blog posts about my travels. Sometimes I rant on Twitter (that one lost me a couple dozen followers).

And sometimes I express my amazement at an inane court ruling: “Yikes! Judge halts stem cell research http://is.gd/eAPR4″. This last statement, to my surprise, has given rise to a bit of controversy online. You can read about it here. Drugmonkey seems to feel that the statement is misleading because it could be read as meaning that the judge has halted all stem cell research (according to the article I linked, the ruling is unclear and may roll back all federally-funded research involving any human stem cells, or it may have a more limited impact).

While I agree that the statement could be misread (I suggested “Yikes! Judge halts a whole mess of stem cell research” as a revision), I do wonder if it’s reasonable to hold journalists’ tweets to the same standards we hold their edited articles and headlines to. A blog post or news article can be corrected, but a tweet quickly takes on a life of its own. It can be retweeted, and even if it’s deleted, it remains on people’s mobile devices and third-party Twitter apps. Maybe this means we should have *higher* standards for tweets.

On the other hand, few people see tweets as the definitive word on something. Unless they come directly from the source (e.g. Lady Gaga tweeting that she’s carousing in Vegas), we don’t take tweets as truth. More typically, tweets point to something else to gain authority — Like a New York Times article about a court decision.

I don’t think I’d enjoy using Twitter as much if all journalists and scientists were as careful in crafting their tweets as they are when they write formal publications. And I don’t think I’m alone. Twitter gets its power from its conversational nature. If everyone on Twitter had to be constantly on guard to avoid statements that might be misunderstood, then few people would think it was worth the bother.
