After going shopping and purchasing my last summer week's worth of food (mostly bagels and things that go with rice), I took a freezing cold shower (the hot water has since returned) and mucked around with the Boston Harborwalk Fort Point Channel mp3 tour. It took me half a damn hour to get the mp3s onto my Zune, by which point I had lost interest -- I'd at least seen the neighborhood before, on the way to taking my GREs (which were successfully reported! despite my never showing ID -- oops?), and I kind of think they're astroturfing some of the neighborhood's cool factor. So I got off the Red Line at Park Street instead of South Station and walked around the Commons and Garden for a bit before starting in on the Freedom Trail, which I followed all the way up to the Bunker Hill monument in Charlestown. I got to walk on the USS Constitution about five minutes before it closed for the evening, which was kind of cool! I have some generally unremarkable photos which I'll probably post eventually. I think it's pretty badass that the Boston Massacre victims are buried right next to Sam Adams. We knew how to agitate, back in our day. Also, brick townhouses on Monument Ave in Charlestown: gorgeous! (Zillow says they're in the $800-1000k range, which might be attainable someday, and WalkScore gives them a respectable 81 for walkability. Though now I'm spoiled - Central Square has a score of 94! Olin? Like, 50. D:) I say things like "yeah, I don't really worry about my future salary" but then things like real-estate break that down.
I really like watching snare drum hits and low bass thumps on oscilloscope visualizations.
What's the difference between a Fast Fourier Transformation and a Fourier transformation done quickly?
Anyway, to-do:
- Show some progress towards any of the mid-term goals mentioned previously (oops)
- Clean out inboxes
- Begin packing
- Clean out room
- Buy some non-ugly clothes for crying out loud
Funny how it looks like the list of things I was going to do this weekend. ;P
- Music:A.C. Newman - Most of us Prizefighters

What's the difference between a Fast Fourier Transformation and a Fourier transformation done quickly?
This an overheard quote or something?
Hooray for to-do-for-the-weekend lists looking like to-do lists for Monday~
And no, for serious about the FFT thing! I mean, a slow Fourier transform isn't something you'd want to do, is it? It's just talking about the speed of the algorithm and not the quality of the results, right?
Oh. Well, essentially FFT is an algorithm for calculating DFT.
"DFT" just means the transformation, while "FFT" means a number of ways of achieving that result which are computationally efficient.
The terminology is confusing because while they both are named as if they're types of transformation, really one's a transformation and one's an algorithm. I suppose that's true of things like sorts, too, though (where you have "sort" as the transformation and "quick sort" as an algorithm). People don't like saying "blah algorithm", I guess????
