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.

The album Another Ticket by Eric Clapton is mostly a blues album with only a few rockish songs. That's pretty typical for Clapton. Curiously, the first 3 (of 5) minutes of the title track is instrumental, which is unusual for album title tracks in my opinion. The only hit single off this record is "I Can't Stand It". According to Wikipedia, this song sometimes gets played during interludes on Bill O'Reilly's radio show. I cannot confirm this, for obvious reasons, but I imagine that Bill does not use it for its original meaning of an ahem troublesome woman. He must want to share something in common with one of his heroes.

I generally like Clapton, and this is a decent album. The only legitimate knock on the album is its bright red cover.

Springtime in Boulder is a tumultuous time. Most evenings the clouds get blown down off the mountains and it rains, and a few times it's turned into snow overnight. The days are blustery and mild, but not what I would call warm just quite yet. The album Arc of a Diver by Steve Winwood does not fit well into my seasonal or geographical mood. If I were in Florida sipping a fruity drink on the beach, I think it would be more appropriate. It would help if I was older and fatter, too. I'm trying to say that if you are in the right place and frame of mind, this album could be quite pleasant. And sometimes pleasant is all you need.

I'm going to try to catch up completely this week.

I have access to some of the fastest computers in the world. I can summon thousands of processors, petabytes of disk storage, and terabytes of memory with a few keystrokes. You'd think with that kind of power, analysis could be automated and done in massive pipelines. But that's not always true. Sometimes things are so subtle that the most efficient method is still to use the human eye.

Today I was pretty ill, with a sore throat and congestion. It was the kind of day for lying on the couch and watching movies. Luckily, I was able to accomplish some work that didn't require too much concentration. First, some context.

One of my current projects is looking at the centers of simulated galaxy clusters, and it is actually surprisingly difficult to find the centers of the clusters. Clusters are complicated places, with clumps of matter falling in, sloshing stuff around, making the core not exactly clear. In order to semi-automate the process, I wrote a script that makes pictures of the clusters (which have been previously identified in a automated fashion), that have density contours superimposed. The density contours are analogous to the lines on a topographical map.

The picture above is an example of the output of the script. The colors indicate gas density, blue to red is low to high. If you look at the full-sized image, you can see that there are two dense clumps numbered 0 and 1. I can't just pick the most dense cluster because that might be a tiny blob of matter falling into the larger cluster; more care is needed. So I need to make the decision with my adaptable brain. The script spits out the image, and then I have to input which clump I think is the most central clump, and a record is made which I'll use for the next step in my chain of analysis. I spent most of today looking at these pictures and entering numbers. Yay for tax payers!

This is very similar to the Galaxy Zoo project that aimed to identify the morphology of actual galaxies, but my effort is on a much smaller and simpler scale.

So - which clump do you think is the most central above?

Luckily for me, I will not draw the ire of any Canadians with this review. In fact, I already had the album Moving Pictures by Rush before this review because I like it. The songs are well made, a couple are catchy, and it's not too long. Go ahead and check out the album yourself!

I wasn't looking forward to Captured by Journey. I've already listened to two albums like this (1, 2) and I was thinking that this album would bore me. I have to admit that I wasn't bored completely by this album, which surprised me. This album is a live album, made up of recordings from several different performances. I think that the energy of the live performances makes the music less soporific, which is good.

If I have one complaint, it's that this album is a bit too long in duration. By the last few songs I was getting kind of tired of Journey. But it took until the end of the album to get there, so that's a small amount of praise. Nonetheless, this is an album you can skip.

I am way late on this review. Many weeks. In my defense, I did some traveling, and the gap that was only going to be 3 weeks just grew and grew. So in the interest of getting back on time, I'm going to do some quick, short reviews until I'm back in sync.

The album Celebrate! by Kool & the Gang has exactly one song you will ever hear: the title track "Celebration". And that's all you need to know. The rest of it is not very exciting.

I will remark that the second song on the album is about divorce. Either it's intentionally ironic to follow a song like Celebration with a song about divorce, or fantastically incongruous.

A gold star to the first person who can figure out what's happening in this photo (click to enlarge). This was taken just an hour ago on my bike ride on Sunshine Canyon Dr. above Boulder. I think everything you need to know is in the photo. Good luck!

Looking at the oldest email I can find, I have been using my Yahoo email address for nearly 9 years. Back then, there was no Gmail as an option. The only other webmail that was comparable was Hotmail. And there was no way I was going to use Hotmail because it was, and still is, owned by Microsoft. For much of that time I have even paid a yearly fee to Yahoo to remove advertisements and add other features.

In the last year I have become increasingly unhappy about Yahoo mail. They have refused to enable IMAP for anything but smart phones. GMail has enabled IMAP for everything for a long time. Yahoo's servers are slow and flaky. Sometimes I cannot access my mail for half an hour (or more) until someone (presumably) does something somewhere to clear it up. I could overlook all of these things, mainly because I knew that switching email providers would be a chore.

However, the last straw was when they added a new feature that allows you to chat with your facebook friends in Yahoo mail. I suppose that this might be useful to some people, but it smacks of "me too" by Yahoo. The faceplace is the new hotness, something Yahoo hasn't been in a decade, and since Yahoo can't innovate their way back into relevance, they've just given up. This is the kind of stuff that insults my sensibilities.

Initially unrelated to all of this, my brother recently purchased a new domain: skory.us. He purchased it primarily so he could make a 10 digit email address: ?@skory.us (? = some letter of the alphabet). I thought that was pretty cool, and I wanted in on that action.

What pushed me to make a decision is that in a couple weeks my Yahoo mail membership comes due, and I didn't want to give them any more money.

Therefore, last weekend I decided to sign up for a free Google Apps account using the skory.us domain. I swapped the MX DNS records over to Google's servers, and started pulling all my old email from my Yahoo account. The pull of 50,000+ emails took over a week and wasn't straightforward. I had to baby sit it daily on each end. THIS is why I was so hesitant to switch email providers because I knew it would be a hassle, and it was a hassle.

The move wasn't perfect - although I pulled all my sent mail (i.e. email I wrote), I can't get it into the Google sent mail folder. And there's still more work to do. I have my Yahoo address in many, many places on the internet that I am going to have to slowly change. In the meantime, the Yahoo email will forward to Google.

Finally, here's my new email address in a human parse-able but obfuscated format. Update your address books!

Taken yesterday on the Betasso Link Trail to the Betasso Preserve above Boulder at about 2000m/6600ft. The CU Campus is visible in the gap at the bottom of the canyon. The horizontal color gradient is due to different exposures & white balances for the individual pictures that make up the panorama. I could probably fix it, but it's OK. As always, click above to enbiggen. Here's the GPS track of the ride.
