The most intuitive, easy-to-follow explanation of Fourier transforms I've ever come across

March 25, 2014

It's here. I found the link when I happened across a discussion of the topic in the Math Stack Exchange. I wish I had seen this way back when I was implementing FFTs in my computer music class in college.  It would have saved me some headaches.

Bonus interesting math thing: The Genuine Sieve of Eratosthenes, a paper by Melissa E. O’Neill.

Prog Rock Day

August 14, 2013

Today feels like a prog rock day. Jumping into the deep end of the pool with the first track off Yes' Tales from Topographic Oceans. 22:22 of pure awesome. And lots of guitar noodling.

A serious question.

March 14, 2013

Question about this new Autechre album: are they really two British dudes, or did the ghost of Iannis Xenakis come to be trapped inside a Macbook that happened to have Protools installed ? Even the title—Exai—sounds Xenakis-ish.

A Mathematician’s Lament

November 28, 2011

A really beautiful little essay by Paul Lockhart about how we learn math now, and how we could do so, so much better. 

 

[M]athematics is an art form done by human beings for pleasure! Alright, yes, it would be nice if people knew a few basic things about numbers and shapes, for instance. But this will never come from rote memorization, drills,lectures, and exercises. You learn things by doing them and you remember what matters to you.

Geohash

March 10, 2011

David Troy has created a very cool visualization of how geohashing works. If you wanted to create your own geohashes (for example, to speed up proximity searches) there's an excellent python implementation of it.

Evaluating CSS3 & HTML 5 features

December 26, 2010

When Can I Use... is a fantastic site to use when you need to decide whether or not to use some of the new CSS3 and HTML5 hotness. It offers comprehensive compatibility tables for relevant versions of all browsers, mobile and immobile, and even links to workarounds so you can just squeak by on using that one feature you just have to have. I'm planning on redesigning this site soon, and It's going to be a big help. Also, IE users, things here will still be readable after that, but otherwise, you're on you own until IE9 is ready for primetime.

Learning Haskell

December 19, 2010

In the process of putting together a presentation on functional programming, I've begun getting into Haskell a bit. It's a bit of a mindbender at first, but I'm enjoying it. For certain types of programming, it's an extrodinarily expressive language. Project Euler is a good example: I've started working through each of the problems, first in Python (a language I know) and then in Haskell. These kinds of math problems are places where a functional language can really shine, and I'm finding that even when judged against an imperative language that I think is particularly elegant like Python, the Haskell solutions often seem more, well...aesthetically beautiful. Fodder for a future blogpost, maybe.

What is Wikileaks Up To?

December 6, 2010

One of the most thoughtful, nuanced, and distinctive pieces I've seen about Wikileaks: 3 Quarks Daily: What is Julian Assange Up to? Contrast this with a fairly dissapointing essay by Umberto Eco on the subject which manages not only to get details about technology and state secrets wrong, but also doesn't really say anything interesting.

What Classical Music Needs

August 30, 2010

From Unblocking classical music's arteries on the blog On An Overgrown Path:

...[G]reat music making only happens when creative energy can flow freely between composer, performer and listener. Yet almost all of the current efforts to reach new audiences involve building the very barriers that block the vital energy flow. Classical music does not need a celebrity culture, it does not need inane presentation, it does not need to be markeketed like cornflakes by PR agencies, it does not need note perfect performances, it does not need national flags on the platform and it does not need the other brands of consultant created snake oil currently doing the rounds.

How to save the news

June 8, 2010

Excellent article by James Fallows about how Google's involvment in the future of journalism.

“Nothing that I see suggests the ‘death of newspapers,’” [Google CEO] Eric Schmidt told me. The problem was the high cost and plummeting popularity of their print versions. “Today you have a subscription to a print newspaper,” he said. “In the future model, you’ll have subscriptions to information sources that will have advertisements embedded in them, like a newspaper. You’ll just leave out the print part. I am quite sure that this will happen.”

Update on an open source project of mine

May 24, 2010

Django-scaffold is now feature-complete. Test coverage is good—somewhere in the neighborhood of 85%—but needs to be closer to complete. Docs are also needed. Once those are done, I'll feel ready to call it 1.0. Well....maybe 1.0 RC 1. It would be nice to get it into production to really see where the bugs are, which I hope to do soon.

Time to disengage from Facebook?

May 9, 2010

There's plenty of evidence that Facebook is more than willing to sell its customers out:

...and ongoing security holes and exploits are a further cause for concern:

I hardly even bother signing in any more. I've been thinking of just closing my account.

A bike shed (any colour will do) on greener grass...

April 22, 2010

 Some of Poul-Henning Kamp's words of wisdom have been floating around in my head lately. Here's a snippet:

I wish we could reduce the amount of noise in our lists and I wish we could let people build a bike shed every so often, and I don't really care what colour they paint it.

Reading this and thinking "Bikeshed? Huh?" Aquaint yourself with Parkinson's Law of Triviality.
