Lock Laces
First, a caveat: What I like about running, as a sport, is that it’s such an elementary activity. There is very little expense or equipment required to get started. All you really need is any old pair of sneakers (if even that). Yammering on about particular kit is a favorite activity of enthusiasts of all kinds, but an interest in details should not be construed to mean they really matter, or that you must be equally familiar with them to be considered legit. Bear that in mind as you read on.
What I’m trying to say is, I’m about to tell you about my shoelaces.
You know the cliché about how long it takes some women to “get ready” to go out? That’s me, getting ready to go for a jog. Indecision about what to wear, or whether I need a hat. Another sip of water. And most of all, tying and re-tying my shoelaces. I’m like Goldilocks: it’s gotta be just right. Not too tight; not too loose. (I’m talking about the shoelaces now, not Goldilocks.)
So, I bought a set of Lock Laces on Amazon for like five bucks. The locks themselves are little spring-loaded plastic stocks for your shoelaces. Press the button to adjust the tension and release it to clamp the laces in place. The laces that come with Lock Laces are elastic, although I suspect they’d work fine with regular laces.
The point of all this is to make it easier, and quicker, to adjust the fit of your shoes. At this point some readers may wonder whether I am in fact even capable of knotting shoelaces in the regular fashion. I am! (And I remember the exact moment, kneeling before the living room stove, when I learned the knack of it.) But it’s nice to get the right fit without a lot of fiddling, and to be able to make adjustments while you’re on the go without pausing for more than a few seconds. That’s especially helpful in winter, when fingers may be too numb to knot laces with aplomb.
There are additional benefits similar to those yielded by the traditional double (or triple) knot: your laces don’t come untied, and the risk of having your foot broken by a shoelace caught in your bike’s chainring is greatly reduced. (Has that ever happened to you? It’s happened to me and it’s terribly frightening, as if an unseen hand had suddenly burst from the earth and gripped your ankle with the ferocious tenacity of the damned.)
“My shoes have stayed securely in place on my feet and my feet have been pretty comfortable. What more can you ask?” – tl;dr summary
Anyway, I have been running with these laces for the past week or two. So far, I like them. I can’t say they’ve really cut down on my “getting ready” time (distractions are easily substituted), but my shoes have stayed securely in place on my feet and my feet have been pretty comfortable. What more can you ask? I do think the elastic laces may count for more than I had originally thought, especially with a combination of flexible shoes and vigorous motion (they stay snug without feeling restrictive as the shape of the shoe changes).
All of the pleasing benefits I have enumerated here probably also apply to Velcro shoes. Sadly, there seems to be a near-total dearth of Velcro shoes marketed to the ambulatory adult crowd.
And yes, my running shoes are fluorescent orange. It helps low-flying planes avoid my wake.
Last but not least, for more more information about shoelaces and knots than you ever knew existed, go check out Ian’s Shoelace Lace.

Weekend Artifact 4
Painting with pencil on a graphite canvas.
I like to draw faces in profile. It’s easier, yes, but I think there’s another reason as well. My doodles are often based on photographs trawled from the web, and it seems the camera is more likely to capture a candid expression when the subject isn’t looking directly at the lens. Almost everyone affects an expression when they know they’re posing for a picture, be it serious or hammy or coy. Those faces are a lot of fun, but I am more interested in unfiltered appearances. Even a face in repose can convey some feeling or story – perhaps that’s what the artist reveals.
That’s getting a little too artsy fartsy for my taste, though. Just look at the pretty pictures!

Minecraft
I recently discovered the game Minecraft. It’s an open-world sandbox: basically, you just build things out of blocks. Technically, there are two modes: creative mode, where you have an infinite palette of materials, and survival mode, where you start with nothing and have to mine raw materials in order to build things and craft other items. In survival mode, there is an optional added challenge of monsters that roam around at night. The presence of these “mobs” imposes some focus on your activity, as it becomes important to build a defensible shelter.
Somewhat surprisingly, I find that I prefer the survival mode. I don’t care much for dealing with the monsters, but planning how to collect or create the materials needed to build interesting structures requires just the right amount of strategy, in my opinion, to keep the creativity fun without becoming frustrating or boring.
(There is also a “hunger” mechanism that requires you to occasionally hunt or harvest food in order to stay active. This only applies when mobs are enabled. Ideally, I would like to be able to toggle these challenges independently, so that I could face the logistical challenge of maintaining adequate levels of both food and supplies without also being harassed by giant spiders.)
Anyway, here’s a dome I built in peaceful survival mode:
The glass (lots of it!) was smelted from sand using charcoal derived from trees I chopped down. Trees are a renewable resource – you can plant the saplings that sometimes drop from their leaves – so, yes, I’m practicing sustainable forestry.
Here’s another sunset scene. As you can see, there are different biomes in Minecraft. This fort was built in a wintry forest with mobs (and therefore also hunger) enabled. It started out as a mere bunker and grew to include the tower and courtyard pumpkin patch you see here:
(The game is updated frequently, so it’s worth noting this post is based on version 1.1.)
The popularity of Minecraft and the apparent vitality of its peripheral economy (subscription-based multiplayer servers; ad-supported map designers and mod-makers; revenue-sharing YouTube channels) makes me rethink the viability of my old idea for a custom LEGO kit store. People do like to build stuff for fun, and will support accessible services that enrich their hobby.

Intro to GIS Presentation
Here is a presentation I created a few years ago to accompany a little talk a gave to the lab group I was working with at the time. Members of the group had acquired some ad hoc GIS experience, but I felt they would benefit from a higher-level overview of common “geographic information systems” concepts and operations. The presentation touches briefly on a number of topics and includes a variety of example images (mostly uncredited, unfortunately; intended for educational purposes only). I have omitted the final slide, which was a segue into a discussion of specific projects within the group. I hope you will find the rest of the slideshow presented here useful.

Reading List integration for Vienna
Vienna is a desktop newsreader for OS X. Here is an AppleScript to add the article currently selected in Vienna to Safari’s Reading List:
Paste it in Applescript Editor, save it in ~/Library/Scripts/Applications/Vienna
, and run it with your script runner to read some articles.
Note: As of the Vienna 3 beta, something like this is now built in to the app: see the “Add to Safari reading list” item in the Article menu.

Custom Kindle Screensaver Images with kite
The Kindle comes with a set of “screensaver” images that appear on the screen when the device is asleep. Most of the images are portraits of famous authors; a few are images of other artwork. All are appropriate choices for the cover of a reading device – but I’d rather use my own images.
Out of the box, it isn’t possible to customize the Kindle screensaver. However, there are couple of unsupported tools that can enable this feature. I tried installing one called kite
and was pleased to find that it worked as described. So I picked out some old drawings and now my Kindle’s got some fresh new faces:

Handlebar Gadgets Pop Quiz
Here’s an only-slightly-fuzzy photo of my handlebars:
Four accessory mounts are visible. Can you identify what they are?
Update: Congratulations to jaster on Flickr for correctly identifying the types of mounts! From left to right, they are: minor light mount, computer (speedometer/odometer/clock) mount, phone mount (on stem), and major light mount.

Reading List Reader
I’ve written a standalone script called readinglistreader.py
derived from my ebook recipe for Safari Reading List. This script simply lists the contents of your Safari Reading List. It has many options to allow detailed control of the output list. By default, output is formatted as a CSV table, but it can also be formatted as a bookmarks file suitable for importing into other programs or services. In fact, since there seems to be no other easy way to grab the contents of Reading List (besides Safari’s interface), this script is intended is to help export your Reading List bookmarks to other services, presumably as part of some other script you write.

A Moment in Motion
A haiku about running in the winter, composed while running in the winter:
Footprints in the snow:
I’m tracking other runners,
racing against ghosts.
(Running west into a bracing flurry on Clifton, I noticed another runner behind me. Our paths soon diverged. Coming down Fuller Hollow twenty minutes later, I saw recent prints, stride-lengths apart, smoothed by just a dusting of snow, and knew I had come upon the trail of my pursuer. As I ran where the other had ran before we met, I came up with these lines to remember the moment.)
