iTunes sorting

Thursday, 8 September, 2011

I’ve been adding a lot of music to my digital collection recently, both by buying some stuff and ripping CDs I own. And so I run into the same old problems with the way iTunes sorts music. Actually it’s even worse on an iPod, because there’s no fancy GUI that you can customise with different columns and views and stuff. You’re stuck with selecting your songs by artist, by album name, or by composer. The problem is if I select by artist, part of the “B”s looks like:

  • Mike Batt
  • The Beatles
  • Bee Gees
  • Jodi Benson
  • Berliner Philharmoniker

Okay, The Beatles and Bee Gees make sense. However, Berliner Philharmoniker is a symphony orchestra. The two albums performed by them that I currently have on my iPod are Holst’s “The Planets” and Beethoven’s 9th Symphony. I also have some Beethoven performed by other orchestras. However, the name “Beethoven” is not on my artist list, because he’s a composer, not a performer! If I want to find Beethoven stuff on this list, I need to look up all the different orchestras that perform his work. And each different orchestra has an unrelated bunch of works by different composers.

Who are Mike Batt and Jodi Benson, I hear you ask? (Okay, some of you probably know already.) Mike Batt composed the stage musical version of The Hunting of the Snark, based on Lewis Carroll’s poem. It was recorded by several artists, and Batt himself performs one song on the album. The rest of the album is scattered amongst several other artists’ names on the iPod artist list. Jodi Benson is the voice of Ariel, The Little Mermaid, who performs two songs on the movie soundtrack album. Again, the other songs on the album are scattered through the artist list.

So, on a quest to find all my Beethoven in one convenient location, I switch to selecting by composer, where the “B”s look a bit like this:

  • Mike Batt
  • Garry Beers, Tony Bruno, The Matrix, & Shelly Peiken
  • Garry Beers, Andrew Farris, & Michael Hutchence
  • Ludwig van Beethoven
  • Chuck Berry
  • Berry, Buck, Mills, & Stipe
  • Berry & Willis

There are about a bazillion composers in this list. Sometimes a rock album will have songs by a dozen different composers! Beethoven is there, but he’s surrounded by thousands of composers I don’t care about, most of whom have one songwriting credit on some rock album. That’s no good.

And how do I find the entire Hunting of the Snark or Little Mermaid, should I wish to listen to the entire albums? I have to switch to a third view, the albums view. This view is not so bad, it does list all the albums as whole items, but the albums by any given artist (or composer) are all split up.

The solution to this? Well, there doesn’t seem to be a good solution. There are web pages and blog posts and forum questions all over the net with people asking how to sort their music better in iTunes. And there are no good answers. One common trick is to move the composer of classical works into the “Artist” field, so you see Beethoven in there with The Beatles and Bee Gees. But then the actual artist has to be deleted, or moved into some other field. It seems nobody has come up with a decent solution to this problem.

I was lamenting this fact at work today, when Andrew suggested that iTunes needs a “Primary” field, which is the primary sorting field you want to use for each album. It can be a radio button that selects one of either the artist, the composer, or the album name. For most stuff it defaults to the artist; for music marked as “Classical” in genre, it defaults to the composer; while for compilations, musicals, and soundtracks, it defaults to the album name. Then you can have a list that uses the Primary field to index all your music, and you’ll end up with a list that looks like:

  • The Beatles
  • Bee Gees
  • Ludwig van Beethoven
  • The Hunting of the Snark
  • The Little Mermaid

Ta da! All your music sorted into one list in a sensible way! You can find everything by the most likely name you want to use, and with no superfluous data cluttering up the list.

How about it, Apple?

Origami notes

Friday, 26 August, 2011

We had a brilliant lunchtime seminar by a guest speaker at work today. She talked about origami.

I wasn’t sure what to expect – if it’d just be demos of paper folding, or cool models that people had made, or what. There were both of these things, but there was much more. The speaker is doing a Ph.D. in statistics, so has a strong mathematical background. She started by showing some examples of origami with a slide presentation. But then… she went to the whiteboard…

She presented origami as a composition of two functions: a first one-to-one (and thus bijective) mapping from a flat sheet of paper to a 3-dimensional folded version of that sheet of paper – specifically a folded version which produces a number of points that can be used as the basis of extremities of a model (for example, animal limbs, fingers, horns, etc); and a second function mapping that 3-dimensional structure to a tree diagram with nodes at end points and junctions. The second mapping doesn’t preserve point correspondences or distances, but (and she proved this as a theorem) points on the tree diagram corresponding to points on the sheet of paper are separated by a distance less than or equal to their separation on the paper.

The upshot of this is that you can sketch a three-dimensional stick figure of anything you like, with correctly proportioned stick lengths; then map that on to a flat sheet of paper such that you produce a tree with nodes and branches in analogous positions such that the distances between them are equal to or greater than the corresponding distances in the stick figure; then from there you can apply a deterministic algorithm to figure out the arrangement of mountain and valley folds to produce the points at the nodes. There are programs that can do this and solve the fold pattern for any desired stick figure in a few minutes.

The result is a map of exactly how to fold the sheet of paper to produce a 3-D model that resembles your stick figure, with the correct number, arrangement, and lengths of all the extremities. From there it’s a simple matter of subtly modifying the shapes of the points with additional folds to produce an accurate model of your desired shape. She showed an example of a buck deer with four legs, a tail, a head with a nose, and two antlers, each with 4 distinct points. The resulting tree has 14 leaf nodes, and produces a complex fold map, but it’s perfectly doable, and the resulting origami model looked amazing.

I was utterly blown away. I always figured origami artists created new models by trial and error and months of hard work. But apparently you can do it with a stick figure sketch and a simple piece of mathematical computer code, in a few minutes. I should stress this only produces the basic “stick figure” form, and the subtle shaping of a 14-pointed piece of folded paper into a realistic deer shape still takes artistic talent, but still, I was amazed that the hard structural part of the work was so tractable and solvable by a beautiful application of mathematics. It shows how mathematics can be applied to surprising fields and come up with usable models and solvable answers for problems that seem unapproachable any other way. Very nice stuff.

Falling in love with Eurythmics all over again.

I can’t believe it’s been 26 years since they released Be Yourself Tonight.

I won an Emmy and didn’t even know it

Thursday, 18 August, 2011

Holy cow.

I just discovered that at least year’s Emmy Awards – almost exactly a year ago – the Star Wars Uncut project won the Emmy for Best Interactive Media.

The Star Wars Uncut project that some friends and I filmed two of the segments for.

We won an Emmy Award.

Yeah, okay, we contributed a tiny part of the whole, and it was all organised and run by other, more deserving people… but….

We won a frakking Emmy Award.

I am so putting that on my resumé.

Puzzle difficulty

Thursday, 11 August, 2011

The 2011 CiSRA Puzzle Competition is in its last few days. It’s hard making new and interesting puzzles, but what’s even harder is figuring out how difficult they are for other people to solve.

We test all of our new puzzles on each other, to make sure that it’s possible for someone to actually solve them. Then we provide feedback and suggestions to tweak the puzzle, make it more elegant, make difficult steps more compelling, provide extra hints within the structure of the puzzle where we think they’re needed. And once we’re done, before we publish the puzzles, we assign a difficulty rating in three relative levels: Easy, Medium, or Hard.

This is a very subjective thing. It’s really, really tough. Of course some people will solve some puzzles faster than others, while other people will find them to be of opposite difficulty. We try to factor in the amount of work, the amount of knowledge, the level of logic needed to progress, and – hardest of all – the difficulty and non-obviousness of any intuitive leaps that you need to make. We come up with a rating, stick it on the puzzle, and then it goes out in the competition.

In Group 4, we published 4 puzzles, three of which we rated Medium, and one Hard. After 24 hours, the Hard puzzle had more teams solve it than all the others put together, and one of the Mediums – in fact the one that several of us puzzle creators thought was the easiest of the group – had no teams manage to solve it. In five years of running this competition (that’s 100 puzzles), we’ve previously only ever had one puzzle go unsolved after 24 hours before, and that was a puzzle we all knew was the hardest thing we’d ever published until then.

But this one, this year… we’re flabbergasted that it proved so hard for the competition teams. Assessing puzzle difficulty… is Very Hard.

The first group of 4 puzzles were released today, and four more groups are released in the week beginning Monday 8 August. Australian students (if there are any reading this) can win prizes of digital cameras, but anyone can enter. If you enjoy a good puzzle, please check it out!

Leon Dormido

Wednesday, 15 June, 2011

Leon DormidoBack in the day, I used to get roughly one of my photos per month into Flickr’s Explore – the top 500 most “interesting” photos posted on the site on any given day. But the rate petered off and now I’ve had a drought that’s lasted almost two years – my last Explored photo was back in September, 2009.

I figure it’s because Flickr has grown rapidly. There are more people uploading more photos, and that just makes it harder to attract enough attention to get a photo into the top 500 of an ever-expanding sample size.

But I was pleasantly surprised to see a raft of comments and likes on this photo, which I posted a couple of days ago. This is a shot of Leon Dormido (“Sleeping Lion”), a volcanic rock spire sticking out of the ocean a few kilometres off the coast of San Cristóbal Island in the Galapagos. It’s a nesting site for blue-footed boobies and magnificent frigatebirds. We circled the rock in our boat a couple of times at dawn to see the frigatebirds in their courtship displays – there’s no landing place on the rock. This shot is as we were leaving it behind, our last encounter with wildlife in the Galapagos. To me there’s that element of sadness in this image – something I guess nobody else picks up just from looking at it. Still, I’m very pleased with how this photo turned out.

Owl Butterfly

Tuesday, 7 June, 2011

Big WingOne of my favourite photos from my recent trip to South America. This is a species of giant owl butterfly, taken in the Peruvian jungle near Puerto Maldonado, a stone’s throw from the Rio Madre de Dios, which is the largest tributary of the Amazon. This is probably the biggest butterfly I’ve ever seen.

Unfortunately I can’t quite identify the exact species of owl butterfly. It somewhat resembles either the Forest giant owl butterfly (Caligo eurilochus), Idomeneus giant owl butterfly (Caligo idomeneus), or Illioneus giant owl butterfly (Caligo illioneus), but not enough that I’m positive about an identification. It may be another species I haven’t managed to find good pictures of to make a comparison. If anyone can make a positive ID, I’d be grateful.

Yes, that’s my wife in the background. :-)

Yoda @ Hogwarts?

Is it just me, or did John Williams re-use the “sparkly” bit of Yoda’s theme in his Harry Potter soundtrack score?
