Journal tags: mathematics

So, remember when I posted all those episodes of Simon Singh’s Five Numbers radio series on Pownce so that they’d have permanent URLs? Yeah, well, so much for that.

Fortunately Brian had saved all the MP3s. I’ve posted them on S3 and huffduffed them all. I can be fairly confident that Huffduffer won’t be going the way of Pownce, Magnolia, Geocities, and so many more.

Anyway, if you want to listen to the fifteen episodes of the three radio series’ on mathematics, you can subscribe to the podcast at https://huffduffer.com/adactio/tags/five+numbers/rss.

Or you can listen to each episode at these permanent URLs:

1. Five Numbers

   1. A Countdown to Zero
   2. Simple as Pi
   3. The Golden Ratio
   4. The Imaginary Number
   5. Infinity

2. Another Five Numbers

   1. The Number Four
   2. The Number Seven
   3. The Largest Prime Number
   4. Kepler’s Conjecture
   5. Game Theory

3. A Further Five Numbers

   1. 1 — The Most Popular Number
   2. 2 — At The Double
   3. 6 Degrees of Separation
   4. 6.67 x 10^-11 – The Number That Defines the Universe
   5. 1729 — The First Taxicab Number

I like Tumblr. I like Pownce. They both make it very quick and easy to post discrete quanta of information. I use Pownce for posting audio files and links to videos. I use Tumblr to post quotations. But both services suffer from the same problem: refindability.

Magnolia and Delicious encourage tagging. Those tags can then surface some pretty interesting aggregate behaviour but first and foremost, they’re useful for the individual doing the tagging. It’s pretty easy for me to track down something I bookmarked on Magnolia even if it was quite a while back. I don’t need to keep a list of all the tags I’ve ever used: I just need to search for a word that I think I might have used when I was tagging a bookmark. While it would be very difficult for me to try to second-guess how someone else might describe something, it’s usually pretty easy to put myself in the shoes of my past self.

As my store of data on Pownce and Tumblr increases, I’m starting to miss tagging (or any kind of search) more and more. Then again, I can understand why both services would resist that kind of scope creep. Both services rely on their simplicity. Adding another field to fill in could potentially be a road block between the user and the task they want to accomplish (although it doesn’t feel that way with Delicious or Magnolia). Update: it turns out that you can tag in Tumblr but it’s hidden behind the “advanced” link. Thanks to Keith Bell for pointing that out.

Here’s a case in point. Over time I’ve been posting MP3 files to Pownce of a series of radio programmes by Simon Singh, author of The Code Book — a superb piece of work. The audio from the radio programmes is available from the BBC website but only in Real Audio which, let’s face it, is complete pants. I originally got the MP3 files from Brian but after a catastrophic hard drive crash, I realised that it would be better to store them at an addressable URL. Besides, I wanted to geek out with my mathematically-minded friends. Pownce’s raison d’être is sharing stuff with friends so it seemed like the perfect home for the Singh files.

But without any kind of tagging or search, there’s no easy way for me or anyone else to revisit just those files at a later date. As a temporary patch, I’m listing the URLs for the Pownce posts that correspond to each episode. If you want to download the files, you’ll need to log in to Pownce.
