Yes, that is my gauche shadow.

I was going to accuse Kim Carnes of being a one-hit wonder with "Bette Davis Eyes" (which went to #1 on the charts, is the lead track of Mistaken Identity and the only song I had heard from this album previously), but I suspect that's because her main genre is Country, and I never listen to Country. She is apparently very prolific and is active even today as a producer with the popular act Kings of Leon.

But the fact that she's not a one hit wonder doesn't change the (other) fact that I generally found this album to be merely fine. Not at all terrible, but not interesting to me. To her credit she has an excellent singing voice, the music is not slipshod, and the lyrics are not nonsensical, but it just didn't appeal to me. My recommendation is to skip this album. However, if you do listen to it and you like it, I won't accuse you of having bad taste in music. Now, if you admit to liking Yoko Ono's music...

Yesterday the Valmont Mountain Bike Park opened up to the public, and today I went over to check it out. The park has been discussed for many years, and developed over the last few, so it's quite a moment for cyclists in Boulder. The park is oriented towards rider development of all ages. Each type of feature, such as cross-country or aerial areas, have options targeted towards riders of all ability levels. And even if you get yourself into something you can't handle, there are bailout options to get around things.

The park is quite extensive and the designers have taken advantage of all the space they had available. Each trail feature is accessible by shared bike/walk trails, so parents can keep an eye on their kids even if they aren't on a bike. Running down the middle of the park are two irrigation ditches (which is a crude description of them, they are much nicer than that) which splits the park into smaller sections. The smaller sections keeps things more intimate which is good in a park that will tend to get very busy. Nearly all of the single track trails are one way, which is very nice. Right now the vegetation is low so it actually isn't a huge problem, but it is always very startling to come around a corner upon someone coming the other way.

To be honest, much of the park makes me feel like I have no skillz (yes, that's skills with a "z"). Even the Skillz Loop, which is designed to be a place to learn skillz without being pressured by better riders to get out of the way challenges me. I tried most of the trails today, but not all of the technical options, especially stuff like this:

The park has two pump tracks, and I had fun riding one of them (Mesa Top) many times. The other one (Creekside) I did once, but it was very muddy and I didn't want to ruin the pump track or get any dirtier than I was already.

The Mesa Top Pump Park

I'm really excited about this new facility, and I hope to slowly improve my skillz over time at the park. It's only a couple kilometers away from where we live, so it's really convenient even if I only have an hour free. My only complaint right now about the park is it's clear they haven't quite figured out how to do the drainage from the sprinklers, because there are more than a few muddy spots around the park that contribute to trail destruction at an accelerated pace.

Someday this could be me!

On our recent driving trip to Yellowstone and Montana, I had lots of time to think about random things while behind the wheel. One of them was to wonder of the major US Interstates, which two come the closest without actually intersecting? My guess was that it's some place on the East Coast, but due to my general lack of knowledge of East Coast highways, I had no idea which two it is.

Being a huge dork, I decided to figure it out.

Basically, it's actually not a very difficult thing to figure out. The steps are:

1. Get the latitude and longitude coordinates for a number of points along each of the interstates.
2. Determine which interstates intersect and eliminate those pairs.
3. Put the coordinates for the interstates into a kD-Tree which will perform the search that determines the distance between non-intersecting highways in a fast way.

It turns out that the first step proved to be the hardest. I decided to use the data from the Open Street Map (OSM) project. This is a Google Maps-like website that is editable by anyone in the world, similar to Wikipedia. It will not give you directions like other mapping services, but it contains the geographical location of a wide variety of items, including and importantly (as the name suggests) roads. I looked into using the OSM APIs, but as far as I could tell either the APIs didn't do what I needed in an efficient way, or the servers were down. So I simply downloaded the 82 GB XML (5 GB compressed for download) dataset for the United States.

Begin rant feel free to skip to the next paragraph. I loathe XML. Any time that you have a 82 GB text file (apparently it's 200+ GB for the whole world) as your main distribution method, you're doing something wrong. Doing this project I learned as little about XML as I could to get just what I needed out of the file. Apparently the authoritative data is kept in a real database, but it appears that you can not download the data as a database. They do have a binary format description, but I can't find a link to download the data in that format. Furthermore, the world doesn't need yet another binary format. For example, they do not discuss endianness for their binary format on that wiki page, which is a big issue with binary formats. There are many other quality formats they could use (SQLite or HDF5). The binary format has a distinct Not Invented Here feel to it, which is nearly always a bad thing. Anyway, back to the main point of my rant. I don't care that the 82 GB XML file compresses down to 5 GB. Reading a 82 GB text file when you're searching for just a fraction of that data takes a long, long time, and is completely unnecessary. Every time I encounter XML it wastes my time in myriad ways. This time was no different. End rant

I'll spare you the full details and samples my low-quality Python code, but I munged the interstate data into a SQLite file, which distilled the data from 82 GB to 19 MB. Yes, that's nearly four orders of magnitude smaller. Then I used the much more convenient (and fast) SQLite file to build lists of interstate coordinates, which were fed into the kD-Tree for the nearest neighbor searches. The results are shown below. Note that there is no I-50 or I-60, and I eliminated I-45 from consideration because it's entirely within Texas, and therefore is not "major" in my opinion. I eliminated Hawaii's H-1 for the same reason. I have included links to maps showing the great circle between the nearest points of the highways. For highways that intersect, the link goes to one of the (more or less random) points of intersection.

Finally, we can see the answer I was looking for. Interstates 70 and 95 come within 5 kilometers in Baltimore at the terminus of 70, but do not intersect. So my suspicion was correct that it was somewhere in the East, so I have that to feel good about.

p.s. If you really, really want to see the code I used for this, I can share it, but I'll have to pull out the hamsters that have taken residence in it. They're attracted to dusty littered places, you know.

Yesterday I rode my bicycle up Lefthand Canyon Road to Ward (up to 10,000 feet in elevation for the first time in Colorado) and on the way down I saw four Moose. Pictured above are three of them: a standing Juvenile, another sitting, and their mother also sitting a bit farther to the right (the tree is pointing to her). A few hundred meters down the road I saw a bull moose, but I decided to not stop again for pictures because I was already late returning home. Combined with our sightings in Yellowstone last week, I've seen quite a bit of wildlife lately! It certainly beats the month in San Diego a few years ago when I saw (or even worse, only heard) a rattlesnake on every other ride.

I am a fan of the BBC auto/entertainment show Top Gear. Often the three presenters, Jeremy Clarkson, James May, and Richard Hammond, will be given a humorous challenge which involves accomplishing some ridiculous set of goals with inappropriate vehicles. A couple examples are crossing the Channel in a car-to-boat conversion and "caravanning" in questionably designed and executed homemade car-to-RV conversions. As a bonus to these challenges, often a pair will work together to sabotage the third presenter's car in some humorous way. A favored method is to (permanently using glue) set the radio to loudly play music disliked by the target. In the case of James, it's anything contemporary, and for Richard, it's progressive rock.

Face Value by Phil Collins is solidly in the category of progressive rock, also known as "prog rock", and every time I listened to it I thought about Richard getting stuck listening to prog rock. There are some aspects I like about this album, most notably the lead track "In The Air Tonight", but the things I dislike the most about this album are actually what define prog rock and annoy Richard the most. Things like directionless piano solos and the over-use of synthesizers. It's those songs that made me feel, well, bored, and stuck listening to the music.

Overall, this album isn't anything special, and chances are you've heard the only good song enough times that you can safely skip this album.

Today Melissa and I went to Yellowstone. I have read that only 3% of Yellowstone's visitors come in the winter, and although it's only a month until Summer, the park was still pretty empty. I figure it's for good reason. The park is still very snowy, and today it was windy, nearly freezing, and often snowing.

The internet at our hotel in Jackson isn't very fast, so here are a just a few photos.

It's really hard to write a review of an album while asleep. Because that's what Dad Loves His Work by James Taylor has done to me. It is a boring, pointless album. I actually like some of his earlier work from the 1970s, but this album is very uninspired.

Furthermore, what kind of musician needs welding glasses and gets his face dirty in the course of his work? The answer is, of course, an awesome one! I have trouble imagining what music that would require active welding might sound like, but chances are it would be more interesting than this easy listening drivel. I have listened to this album twice, and I hear no evidence of welding sounds. The cover is definitely false advertising.

Furthermore, again, I can't figure out what James Taylor's fatherhood has to do with anything on this album. It's hard to tell, like I said, because I'm asleep, but there are no songs about or to his children. The album could equivalently be titled "White Male Loves His Work" or "33 Year-Old Lennoxian Loves His Work". If he's implying by the cover and the title that he loves to weld, I'm just confused, and so his he.

Huzzah! With this review I've caught back up to my review schedule. In fact, the next review isn't due for a week and a half.

I have heard from a couple people that Yahoo! Mail will not send messages to my new email address. Below is a screen capture demonstrating this (not that I doubted them):

My email address is indeed valid, and I have now sent and received hundreds of emails using it. Furthermore, the specifications for email addresses are very simple, and my email address follows them (obviously). Yahoo! clearly needs to hire someone who can read a Wikipedia page and write a simple regular expression validating email addresses. Actually, a quick Google search (natch) proves that this has already been done dozens of times.

Just yet another reason why I'm glad I finally switched away from Yahoo! Mail. Good riddance.

Interestingly, although this is the second AC/DC album I've reviewed as part of my 30 Years On project, Dirty Deeds Done Dirt Cheap in fact originally came out before Back in Black. This album was released in Austrailia in 1976, and only came to the `states in 1981, after the 1980 release of Back in Black.

I suspect that AC/DC was a major inspiration for the 1984 mockumentary (that I think is brilliant) This Is Spinal Tap. In fact, I think a straight line can be drawn from AC/DC's song "Big Balls" to Spinal Tap's "Big Bottom". If you enjoy Spinal Tap, you're likely to enjoy AC/DC and this album.

Most of what I said about Back in Black can also be applied to this album. AC/DC is fun band to listen to if you're in the right mood. However, because the songs on this album don't quite get the same airplay as those on Back in Black, this album is worth checking out at least once.

Here's a quick and simple review of Winelight by Grover Washington Jr.:

• Every time I listened to this album I felt over-dressed. No, I never listened to it wearing a tuxedo or a three-piece suit. I mean that wearing any clothes at all is being over-dressed for this album. It's that kind of album.
• It has only one song on it you've ever heard, Just the Two of Us, and likely only because you saw it in Austin Powers 2.

In summary, if you're naked, go ahead and listen to the album. Or, you can watch Austin Powers 2 and hear the only song on this album you care about, but see some funny stuff happen at the same time. What's funnier than little people?

Two days ago it was nearly 30C/85F in Boulder. This morning I woke up to snow falling outside our windows (but it wasn't sticking because it was just above freezing where we live). It's now changed to rain, but as the picture above shows, at just slightly higher elevations the snow is sticking. The forecast says that within a week we'll be back near 30C. Living with four seasons is interesting!

Face Dances was the first album put out by The Who after the death of Keith Moon. I'm not familiar enough with The Who to know if that had an effect on this album. I'm guessing it probably did. The best I can say about this album is that the songs are all very "poppy" and the lyrics and melodies stick in your head very easily. But overall, it's a fairly unremarkable album and probably got on the top-10 due only to the strength of their previous albums. The fact that the band disbanded two years after this album came out is a good sign that they were already on the decline as a creative unit.

According to the Wikipedia page, the cover artwork was commissioned from various famous artists. Judging from the top and bottom rows, it looks like the artists were handed the same photos. The bottom row is the most disappointing - three of the frames are basically identical, and I'm guessing they filled in the fourth with random icons to break the monotony.

Edit: Anyone want to proffer a guess what the middle-row, left-column icon is?

My recommendation is that this album is not worth checking out.
