But could you explain variables and arrays in terms of spreadsheet cells and rows (or columns)? That is what I was thinking would be useful.

It's good for doing one-time analyses, but hard to automate when you have many inputs that are updated as time passes, or if you need to feed the output of one spreadsheet into another. Tangentially related: I've been thinking recently abou

To play the devil's advocate, I'll point out that anyone selling in multiple currencies has to deal with hedging fx risk. For example, USDJPY has been pretty nuts thus far in April (not BTC nuts, but intraday swings of 1-2%). If you were 1)

Harper Reed and Scott VanDenPlas did a talk / Q&A at the Chicago AWS meetup group a few months ago. My hazy recollection of the salient points of the talk: 1) This represents a heterogenous set of services where the engineers in charge

1) Regulatory issues are a big question mark. 2) There isn't actually that much volume compared real electronic exchanges. Just looking at the Mt Gox page from today it looks like $30MM USD worth of bitcoins have been traded. Hard to make a

The problem is moving the counter currency around. I can zap you some bitcoins without any problems, but it's much harder for you to zap me back some USD (or EUR, JPY, whatever).

If they're going to pay back in cash, I don't understand how they do that at $2MM/year in revenue. Essentially all of their revenue would go to payments on the debt. I suppose they could be planning to IPO in which case they could use some

Can you expand on this a little bit? What does a company like Foursquare post as collateral on a $10mm+ loan and what are typical interest rates? Will Foursquare be expected to pay back the entire loan in cash?

We're talking about opening a short position in the face of manic buying. Buyers will still vastly outnumber sellers, and in the end you'll be forced to buy back at a higher price in a so-called short squeeze which will drive prices even hi

Yes I was just walking through the mechanics of a margin call on a short position that goes sour. Lots of people understand that shorting helps you profit when prices decrease, but not everyone understands the risks, especially in the face

The people here talking about shorting bitcoin to moderate the bubble have no idea what they're talking about. Shorting a bubble is about the stupidest thing you can do. Here's how that math works: 1) You open a margin account with $10,000

In 2005 Yahoo buys Delicious, a bookmarking site, for between $15MM - $30MM. Summly was acquired for a reported $30MM. Delicious had 5MM users, and let's face it how much "CS beef" goes into a bookmark sharing site. Summly claims to have 1
