The C major scale consists of C-D-E-F-G-A-B-C. The A-minor scale consists of A-B-C-D-E-F-G-A. Those are the same notes, but if you play each of those patterns on a keyboard, the first one sounds happy, the second one sounds sad.
A C-major chord (technically, triad) is made up of C-E-G, the first, third, and fifth notes of the scale. Again, sounds happy. The A-minor triad is A-C-E ... sad.
But if you play a melody -- that is, one note at at a time -- it isn't always clear whether it's happy or sad. In most western music, though (including virtually all pre-1900 classical music and the vast majority of modern pop), the piece will end ("resolve") with a clearer "happy" or "sad" type of chord. That final chord is what determines the key.
(In a huge amount of classical and popular music, the final chord is the same as the opening chord, but not always. When they're different, the final chord tells you the key.)

Not a very generous multiplier, but then again, the actuarial tables for a headless chicken wouldn't be all that favorable.

It was a great experience, and here's what I'd change:
- spend more time in fewer places; be less of a tourist. (bonus: for the most part, the less you move around, the less expensive it is.) I would particularly try to do this in places that aren't typical tourist destinations. Think of stops of 1-3 months (perhaps with side trips) rather than 1-2 weeks.
- if you're traveling with someone else (particularly a significant other): (a) be really, really confident that you want to travel together for that long; (b) do whatever you can to find destinations that you both are interested in; (c) explicitly acknowledge that you will want to spend time apart during your travels; and (d) expect the relationship to get rocky at times even if you do all of the above perfectly. It's hard.
- Plan to return to your current home, if at all possible. I didn't do this, and re-adjusting to 'normal' life was much more difficult without an existing set of family and friends around. Even if you do go back 'home', re-entry won't be seamless. One of my friends spent two years in Japan and claims that she was more homesick upon returning home (USA) than she ever was in Japan.

Again in my experience, Amazon's discounts do not effect the author's take. At least in CreateSpace, the author's royalty is based on the retail price the author sets.

And, as other responses have pointed out, in all of these fields, people really, really want to do them. The number of writing jobs that are 'comfortable' (pick your number, $60k?) has sharply declined from the glory days of the newspaper industry, but it still has the same non-monetary attractions, and there are the still the same opportunities to become, say, a bestselling nonfiction author.

Astoria is relatively cheap (as noted above) and safe; other nearby neighborhoods in Queens can be even cheaper, if not quite as safe (Sunnyside, Long Island City), and if you are commuting to midtown (or in my case, not commuting at all) you're looking at <30m.
IMO, Brooklyn apts tend not to have the same value, taking safety and commute time into consideration, but plenty of people would argue with me on that point.

What I think is valuable is the constant reminder that the business/income-building is a means to an end, and there's a wide world of choices out there for what the "end" is.
jsackmann | 15 years ago | on: Ask HN: What are you reading right now?
In case you (or others) don't know, the movie Gettysburg is based on The Killer Angels, with the same focus on Lee and Chamberlain. It's very long, but good -- much was filmed on site, and Pickett's Charge is done in real-time. Harrowing stuff.
Also, let me plug the battlefield itself -- I just visited a couple of weekends ago for the first time as an adult. If you've read about it or seen the movie, it's a fantastic place to see. Unlike some Civil War battlefields, standing there really makes it clear -- you can look down from the top of Little Round Top, and you can look across the field of Pickett's Charge from both directions.
jsackmann | 15 years ago | on: A year of Geek Atlas sales (some facts about book royalties)
I recently published my first book through them [1], and imho, it looks good. I formatted the book itself in LaTeX and had a graphic designer do the cover, which cost me a couple hundred bucks. It doesn't look exactly like a typical textbook, but that's much more because of some first-time mistakes of mine than anything about the production process.
Also, not sure what "a lot of upfront fees" are in this case. I paid for my cover, but that's not required. They offer a plan for $39 (iirc) that gives you a better royalty deal. But that's it.
