There are lots of updates. I think it's definitely worth getting if you liked the 1st edition. ( Full disclosure : I am the author.)

With the 20% discount it's only $5 more now that it was yesterday. (The coupon code is '2ndEd'.)

In this vein, there's a wonderful article by Edward Purcell called "Life at Low Reynolds Number": http://brodylab.eng.uci.edu/~jpbrody/reynolds/lowpurcell.htm... (Purcell won a Nobel Prize in Physics for his discovery of nuclear magnetic

Many Kindles can read PDFs, and the Rails Tutorial book is designed to look good on those. Eventually I may release a mobi format as well, but it's a pain to make, and I find that both mobi and ePub are rotten formats for technical books.

You make some good points, but your tone is too strident. Please keep HN discussions civil.

You make a good point, but in this case I think it's implicit in their form that you're joining a list of some kind. Otherwise, they would just have a download link.

That's not why. You can live in Singapore as a permanent resident for the price of starting a corporation ($150), which then simply hires you as an employee. Or you can have $20m and qualify for an investor exception—for which I'm pretty su

The tax revenues we're talking about here are roundoff errors to USG. This is just pure spite.

You're criticizing my paraphrase of DHH, not my actual point. That point was "companies with a huge number of users are valuable, either as eventual cash cows or as strategic acquisitions, but at best following that route is a risky strat

The benchmark is profits. "Instapintora" might work out well for its founders, but DHH argues that grabbing a ton of users and hoping for the best isn't a good general strategy for building a business. I'd amend that slightly by saying that

You're probably right. Maybe in an audio interview the irony would have come through.

You are an M.I.T.-trained mathematician and physicist. How did you come to work on obesity? ...I didn’t even know what a calorie was. I call bullshit.

Would people be so torqued up if this were a wrongful imprisonment in Massachusetts instead of a wrongful execution in Texas? I doubt it, which suggests that this story may be pushing buttons in your brain other than injustice == bad . Wro

As a thought experiment, imagine the change in Microsoft's market cap if tomorrow they announced that Steve Ballmer was stepping down and Bill Gates was returning as CEO. The result, at least in my mental model, doesn't reflect well on Stev

This looks promising. There are two big questions I didn't see answered in the FAQ: (1) Who are you? (2) What do you get out of the program? P.S. The design of the site is awesome.

Consider a limiting case. Upon hiring employee 50, you have to sell your company and donate the proceeds to charity. I hope that sounds crazy, but in case it seems warm and fuzzy bear in mind that all 50 employees are now out of work. Are y

Thanks! The view counts are low because I just announced their release today. Before now, only people who bought the screencasts knew about the links.

I'm not sure what you mean. Could you elaborate? Do you mean links in the actual video? I'm relatively new to YouTube uploads, so any assistance would be much appreciated.
