10 Ways for the Lazy Geek to Lose Weight

So, you’re a nerd (or a geek, if you prefer). You spend your life sitting in front of your computer, your TV, or your latest book. You don’t play sports, you don’t go running, hiking or cycling, and the word gym conjures up painful memories from middle school.

And you’ve put on a bit more padding than you’d like.

The problem is, you can’t stand exercise, you don’t want to spend the next 2 months eating cardboard food, and you don’t want to record your every caloric intake with a spreadsheet (though if that idea appeals to you, go for it). What’s a geek to do?

Well, here are some tweaks you can make to your lifestyle that, with a minimum of effort, will help. They won’t take the weight off quickly, but they’ll lower it over time. And you might be able to keep it off better than someone who goes on a crash diet, because you’re changing your habits, not just making a short-term change. Read the rest of this entry »

Missing Posts Found

Five posts since last weekend didn’t show up properly in the feed, so if you’re following by RSS or LiveJournal, you probably missed these:

• No, They Don’t Read — A study finds out just how little people actually read on the web.
• Hazards of DRM on Music (or video, or any other media) — If the DRM provider ever shuts down (as Microsoft is shutting down PlaysForSure), the tracks you bought will be a waste of bits.
• Efficiency at the DMV — no, really!
• Weirdest Spam Yet — It’s NOT your fault that your spells and rituals aren’t turning out like you want… YET.
• Judging a Book’s Cover — Historical novels that reuse the same covers, sometimes many times over.

(For the record: the GMT timestamps were set to zero. It seems to be this problem, probably triggered by turning on the XCache-based object cache last weekend. I’ve applied a patch, so let’s see if it works.)

No, They Don’t Read

It’s clear that a lot of people don’t actually read web pages before they respond to them. They’ll do things like…

• Contact someone with a similar name, even when it’s clearly the wrong sort of organization — say, a student writing club and not the bookseller that’s been causing them problems.
• Ask a blogger for a job application for a company mentioned in the post.
• Ask unrelated tech support questions on a blog post because they used the wrong search terms for their problem.
• Ask for help creating Flash animations on a forum dedicated to the Flash super-hero, then get indignant when people have the gall to point out that they’re in the wrong place.

Now, usability guru Jakob Nielsen reports on a study showing just how much people don’t read. In the average visit, users only read 28% of your text if you’re lucky. You have to drop way down — to 111 words — just to count on visitors reading half of it.

Depressing, but it explains so much. And it suggests there’s a benefit to highlighting key phrases. If they’re only going to read ¼ of the text, you may as well make sure it includes the important stuff.

Efficiency at the DMV

Yes, I’m shocked as well. This morning I had to go into the Department of Motor Vehicles for the first time in several years, and was surprised to find that they’d actually worked out a very efficient system for handling people as they came in. I don’t know if this is standard across the California DMV, or if it’s specific to the Laguna Hills office, but I was impressed.

It’s a 2-stage system, starting with a single line, then a set of take-a-number queues running in parallel.

1. Everyone starts in a single line leading to a “Directory” desk. The clerk at this desk handles initial questions and hands out the appropriate forms.
2. You fill out the forms, then go back to the desk without standing in line again.
3. The directory desk assigns you a number in one of several queues, depending on the type of service you need (ID, license, registration, testing, etc.).
4. They call your number and send you to an open window.

The thing that impressed me was step 2. They have you fill out the forms before they assign you to a queue. That means that you won’t get caught half-way through the form when your number is called, so clerks at the windows don’t have to wait around while you finish filling things out. That means they can handle more people in the same amount of time.

The only problem I noticed with this part of the system was that it wasn’t clear where to go if you had an appointment.

Well, that and the occasional clueless visitor. I felt really stupid after marveling at the simple optimization, then discovering when I got to the window that I’d missed a section.

Ben Stein Compares Scientists to Nazis

Well, what little respect I had left for Ben Stein is rapidly evaporating. Apparently it’s not good enough for him to claim that “Darwinism” leads to genocide in Expelled, now he’s running the interview circuit making statements like this:

When we just saw that man, I think it was Mr. [PZ] Myers, talking about how great scientists were, I was thinking to myself the last time any of my relatives saw scientists telling them what to do they were telling them to go to the showers to get gassed.

or this:

Love of God and compassion and empathy leads you to a very glorious place, and science leads you to killing people.

Now, let’s leave aside all of the lives saved by medicine, engineering, and other applied sciences for a moment.

And let’s ignore the fact that Stein said this on an interview with the Trinity Broadcasting Network. On television. About a movie. Both products of science. (I wonder if he ever sees doctors, or takes medication.)

And let’s table the fact that he seems to think (or finds it convenient to claim) that evolutionary biology and Social Darwinism are the same thing.

And let’s not even bring up the fact that the Holocaust was rooted in centuries of anti-Semitism, and the most scientific thing about it was the means of execution. Or that even the ADL is upset that the film “misappropriates the Holocaust,” pointing out that “Hitler did not need Darwin to devise his heinous plan to exterminate the Jewish people and Darwin and evolutionary theory cannot explain Hitler’s genocidal madness.”

And God forbid that we mention all the people killed in His name.

No, let’s not mention any of that. Let’s focus on one specific item:

In internet culture, there’s a concept called Godwin’s Law. It was an observation that, as long discussions continue over time, eventually someone will compare the other side to Nazis. A tradition has developed that once this happens, the discussion is over because no reasonable debate can be had when one side thinks the other is just plain evil. Generally, whoever makes the comparison is considered to have forfeited the argument, because they couldn’t think of anything else to support their side but stooping to the basest ad hominem attack imaginable.

At least he’s come out in the open and admitted that the movie isn’t just about suppressing the theory of evolution, but is explicitly anti-science.

Rainbow Feather Cloud

On my way back to work after lunch today, I looked out the window and saw this feathery wisp of cloud with a clear rainbow pattern running from red at the the top to violet in the middle, then turning plain white below.

As I drove south, the colors moved down the cloud, disappearing entirely by the time I got back. By the time I could safely snap a photo, it was already more or less midway down the cloud.

I believe it’s a fragment of a circumhorizon arc, judging by the description:

Look for a circumhorizon arc near to noon near to the summer solstice when the sun is very high in the sky (higher than 58°). It lies well below the sun — twice as far from it (two hand spans) as the 22º halo.

The arc is a very large halo and is close to, and parallel to the horizon. Usually only fragments are visible where there happen to be cirrus clouds.

We’re still 2 months from the summer solstice, but it was 12:38 PM DST (half an hour before true noon), and the sun was apparently near 70.6° high. (The site is aimed at UK visitors, after all.) It also looked too far away from the sun to be part of the 22º halo, plus of course the colors were more well-defined.

This also points out the should-be-obvious fact that ice crystals can still form in the upper atmosphere even when it’s warm — say, 90°F — on the ground, so there’s no need to limit halo-hunting to winter.

I recommend checking out Atmospheric Optics’ additional pictures of circumhorizon arcs, most of which are more complete than this one. Some of them quite spectacular and must have been really impressive to see live.

There’s a convention for everything

Here’s a weird one. it turns out that ROFLCon, dedicated to all those Internet fads, was held at MIT this past weekend. Found via the Mozilla blog: Firefox Spotted at ROFLCon (look there for a picture of a life-size Firefox mascot with Tronguy).

Links: Freedom and Security

The CBLDF has issued a press released detailing the victory in the Gordon Lee case. This was the case in which a comic book store in Rome, Georgia, as part of a 2004 Halloween promotion, was handing out free comics left over from that year’s Free Comic Book Day. Among over 2,000 comics, they accidentally included a copy of Alternative Comics #2, which included a story about Picasso which included him running around his studio in the nude. And they accidentally gave it to a kid. The parents wouldn’t accept an apology, and pressed charges instead. The DA has been determined to make an example out of him, pushing grossly overinflated charges including felonies that would have given him prison time. 3½ years, 3 trial dates, a mistrial for prosecutorial misconduct, and $100,000 in defense costs later, the Rome DA finally agreed to drop the case in exchange for a written letter of apology — which is exactly what the store owner had offered in the first place.

Easy Office Environmental Tip: The Disposable Cup

If you work in an office, chances are there’s a water cooler somewhere. And if there’s a water cooler, chances are there’s a stack of disposable paper cups (or possibly, even in this age, styrofoam). And chances are that most people will walk up, grab a paper cup, take it back to their desk and then throw it away.

Of course, all those paper cups end up in a landfill somewhere. And there’s the material to manufacture them (even if it’s recycled). And there’s the energy that went into manufacturing them.

So why not reuse that paper cup if you’re only using it for water? It’ll dry out between uses, so the water shouldn’t seep through the wax. If you have, say, one glass of water a day, and you use the same cup for a week, you’re cutting down your paper cup usage by 80%.

Or better yet: do you have a coffee mug? You need to wash it out anyway before you put more coffee in (unless you’re keeping it full all day long). Why not wash it out earlier, and use the mug when you want some water?

Sure, it’s less convenient than walking past the lunch room and grabbing a new paper cup. But let’s face it: you work in an office. And Americans, on the whole, don’t get enough exercise. You might as well take advantage of the extra activity for some incidental exercise.

Under Construction Indefinitely

We went to Wayzgoose at UCI on Saturday, which meant getting our annual taste of what’s changed about the college campus. I’d caught the new Student Center last fall, but Katie hadn’t been back since last year, before it was finished.

Some of the meeting rooms buried in the hill still remain from the previous building. In a food court next to the bookstore, I found a window looking down on this familiar-looking atrium.

Through the glass paneling is a stairway that leads up to the ring road entrance. Clone Copy and Clone Notes used to be on the lower floor to the right (off-camera). In the mid-1990s, the area below the overhang to the left was a pool hall whose name escapes me. I think they converted it to a study area when they remodeled the upper floor to create Zot Zone (which has since been demolished and relocated). The area where I was standing used to be an outdoor walkway connecting the main courtyard to the bookstore.

What was really odd was the west food court, where my brain kept trying to overlay the old layout even though I’m sure they ripped out and replaced that section of the building entirely.

The sad thing, though, was that they’re tearing up the large grass area in the middle of the Claire Trevor School of the Arts and putting in another building. Everything in the quad bordered by the Claire Trevor Theater (formerly the Village Theater), the Studio Theater, the scene shop, Studio Four, and the drama offices is a big fenced-off area of dirt.

Aside from the usual uses for a lawn, it was a great place for people to rehearse. It’s not clear how much of the fenced-off area will actually be turned into a building, but they may have finally finished paving the entire school.

I found it a rather ironic discovery to make at this time, considering that Wayzgoose/Celebrate UCI is also combined with Earth Day.

Sci-Tech Links

Scientists have built a computer model of the Neanderthal vocal tract based on fossils, and have simulated the kinds of sounds they could have produced. Ever since I read Robert J. Sawyer’s Neanderthal Parallax novels, I’ve been fascinated by the idea that there were two distinct human species, living side by side, for perhaps thousands of years. What happened to them? Did our ancestors kill them off, or interbreed with them? Did they fail to adapt to a changing climate? (via Slashdot)

On a related note, it seems that Expelled, the anti-science propaganda film that actually invokes Godwin’s Law by claiming that “believing” evolution leads to Nazis, opens this weekend. I’m curious to see how badly they misrepresent things (it’s always best to look for yourself, instead of just taking other people at their word—that’s the whole idea behind science, after all), but I can’t bring myself to support them by actually giving them money. Meanwhile, Expelled Exposed is interesting reading.

Somewhat(!) less controversial, InformationWeek reports that Windows XP SP3 may be out as soon as next week. This reminds me: I really should look up some reviews of Vista SP1 and see if it’s improved matters any.

Still in software, dria.org explains why the AwesomeBar is awesome. That’s the nickname given to the new address bar in Firefox 3, which lets you search your browser history as you type. It’s the reason I never went back to Firefox 2 after trying out one of the later FX3 betas, and why I’ve installed Fx3b5 on two more machines. The Opera 9.5 previews have a similar feature, but Firefox’s implementation is better visually. It’s easier to spot the page you want, and over time, it learns which pages you visit more often. It’s so much faster to type a word or two than to hunt through the bookmarks menu. (via Asa Dotzler)

Conventions and Distance

You may have noticed I’ve been thinking about fan conventions lately.

It started after last year’s Comic-Con, when I decided I wanted to go to something a bit less…intense. Last year’s Wizard World LA was nice, but a bit sparse, so I went looking for more comic and general sci-fi/fantasy cons within driving distance of the LA/OC area. Surprisingly, I didn’t find much. Gaming conventions, costuming conventions, Anime Expo, sure, but sci-fi? Pretty much just Loscon, which we both gave up on after 2002 (and from what I’ve heard, hasn’t picked up again). I asked around a bit on some forums, and someone on either Comic Bloc or Newsarama suggested WonderCon, and suggested considering the city as a vacation destination, not just a place to find a hotel for the con.

Since WonderCon worked out so well, I’m looking at what else might be fun. That’s part of why I did my price comparison last month, and Kevin Standlee’s comments got me looking at WorldCons and the like again. Not for this year, but maybe a few years out.

Looking at all these cons, I realized that beyond a certain threshold, distance doesn’t matter. Only the destination. If it’s far enough away that you have to fly, the only thing that distance impacts is the cost of your plane ticket. Whether your flight is 5 hours or 10 hours*, it’s still going to take up most of a day or night when you factor in dealing with the airports. Everything else, from hotel prices to whether you need a passport, a phrasebook, or currency exchange, is a factor of the destination.

WonderCon, I think, was at the boundary of driving distance from here. We could make the trip out in one day, but it was a lot more fun to break it into stages and make it a road trip. San Diego is at the boundary of commuting distance. We could drive out there in the morning and drive back at night (and I did that with my parents for over a decade), but it’s not practical to do for more than one day. Whereas if I wanted to, I could easily commute to Wizard World Los Angeles 2 or even 3 days. (As it was, we only went for Saturday.)

With two cons in Q1, and San Diego coming up in July, any traveling we do later this year is probably not going to be convention-related. As it is, we’ve talked seriously about three possible non-con vacation spots. But it might be worth casting a wider net for cons in 2009 or 2010.

*Katie and I were talking about this, and realized that it’s probably different if you have kids. In that case, a 5-hour flight probably would be significantly harder to manage than a 3-hour flight.

Backwards

From a food allergy alert released today:

Cracker Barrel Old Country Store, Inc., is recalling “Chocolate Covered Almonds” due to undeclared peanuts and “Chocolate Double-Dipped Peanuts” due to undeclared almonds. [emphasis added]

I have to wonder: are they just really bad about keeping their ingredients separate, or did they get the labels switched on a couple of batches?
