The survey showed that as much as 86% of developers listen to music while coding. Of the major music genres, 42% of developers said they prefer coding to music of the rock/pop variety.

The results also included the top artists, some "guilty pleasure" choices and some of the least popular artists. The full results of this survey will be coming out in January 2012, giving a "developer perspective" on the current state of the industry, technology in general and their career.

So what is the book about? Basically, it is a programmer efficiency guide. It goes through several tools, pieces of software but also development approaches that will make your developer life easier and more efficient.

He goes on to talk about the two main sections of the book - Mechanics and Practice - and what's contained in each. Stefan also points out a few things that he learned as he went through the book including a strong push for automation, how some of the ancient philosophies still apply to development today and the motivation to question how things "have always been done" to look for a better way.

I have been able to touch type since about age 12 and can manage about 100 words per minute when faced with blocks of text to copy and even faster if I am just writing code. [...] Programming in C meant a lot more typing of parenthesis and a lot more thinking about the structure of the code.

PHP has introduced another set of typing problems with a lot more use of < > and a much higher mixture of variables/functions/parenthesis plus the added bonus of trying to remember a single function from a choice of 3000+.

Several of the comments on the post suggest that it could be helpful to productivity, but shouldn't be focused on too much. After all, what really matters is the programmers skill, right?
