Draft Unix manual written by Dennis Ritchie circa 1971---at a time when Unix had been running for a "few months" on the PDP-11.

Here's a great blog post on insurance and healthcare: https://healthcareinamerica.us/how-to-ask-good-questions-abo... I think insurance is not an accurate word for the health care industry. I, like you, think of that

By default, the erl interpreter starts up the otp app, which loads lots of modules (50+?) and multiple (5?) different processes. It takes a second. To get things running faster, you can use the -boot argument to erl. There is a appendix

Wow, they sure don't. In fact, nationwide gas tax and tolls cover about 32% of highway costs. [ http://taxfoundation.org/article/gasoline-taxes-and-tolls-pa... ] (But that just says to me our gas taxes should be hi

I don't hate it, but I do question if it is the best use of funds. The U.S. doesn't have the density required to support the transit systems we have built. Fare box revenue only covers 44% of operating costs in Boston; in Austin

The benefit I see is that (at least in Erlang) pattern matching combines pre-condition asserts with programming the sunny path. For example, "/" ++ X = HttpRequest:get(path). will crash if PATH_INFO doesn't incl

Nice. Here's an Erlang version of your code, which I think reads even more like math: gcd(A, B) when B == 0 -> A; gcd(A, B) when A < B -> gcd(B, A); gcd(A, B) -> gcd(B, A rem B). I also really appre

> Nokia 635, $40 I don't understand why these low cost Nokia's get so little love here in the U.S. My 520 was $50 a few years ago and is a rock solid piece of hardware. I guess it's the missing apps on Windows mobile?

They created a ton. Transistors, solar cells, lasers, satellites, cell phones, LEDs, UNIX and C all came out of that monopoly. That's an unparalleled track record of technical innovation.

FWIW, I found shmig [1] much simpler than sqitch. Last I used sqitch, it returned a zero value on error, which made me leery of using it for scripted deployments. [1] https://github.com/naquad/shmig

Actually, discovered ledger-cli here last week (thanks HN). It's amazing. Abstracting currency to the concept of commodity + price files makes it trivial to track your shares in 401k, and have the current market value print on the ba

The models certainly contributed. (Note: I have read this far in the book.) The modeling error in question was independence; that is, if you have five mortgages, each with a 5% change of default, then these can be packaged up as an AAA sec

So, if the method was commented, would you: (A) assume the comments are correct and skip reading what the code does? (B) use comments as guidance and read code anyway? The first seems awfully risky to me and poor advice to any programmer tr

This talk is very informative. The historical bit about NASA using event-sourced design for the Apollo Program (1969) was pretty interesting. He gives IBM big props for hitting 2,300 transactions/second in the mid-60's (with IMS aka DB1).

There are supposed to be Chinese walls. If you read the article about Ted Parmigiani in last Sunday's New York Times, it seems the walls can be like the one in A Midsummer Night's dream. http://www.nytimes.com/2012/05/20/business/is-insi

Last month Forbes reported that Netflix said 75% of what it's customers watch are from recommendations. Definitely some bang there. Also, note that 10% improvement was far from linear: year 1: +8.43%, year2 +1% and year3 +0.6% (!!).

Keeping variable names short is a natural brake on routine length. Like wrapping at 80 columns and using tabs is a natural brake on deeply nested conditionals. If I need a longer variable name to clarify the intent of the code, it's a sign

blocking / non-blocking has nothing to do with language; for e.g., see tornado for async request handling in python.

I have been using event-based persistence, and while performance is definitely a bonus, the win for me is the ability to replay the transaction log. For example, let's say you log each page view and include the referer in that transaction.
