Comments about O'Reilly Media Erlang Programming:

My copy is falling to pieces through overuse.

A beautifully written and skilfully edited reference book that brings Erlang to practical life. Even better than Joe Armstrong's Programming Erlang book, which is itself great.

Congratulations.

The best Erlang book I read

Comments about O'Reilly Media Erlang Programming:

My first involvement with Erlang was while I had this book as a guide. I had no significant experience with a functional programming concepts or "real concurrency".
I had been disillusioned about concurrency by using Python (aka Python threads).
This is the main reason I have decide to investigate Erlang.

The book starts of with an interesting history and overview of Erlang, an introduction to concurrency, system robustness in distributed computation. Also included are a comparison to C++, and of course the "Why should I use Erlang" section.

"Erlang Programming" is well-organized and covers enough of the key topics for a beginner to get started using Erlang as well as some advanced topics.
The author takes you through sequential and concurrent programming using Erlang as well as pattern matching, message passing, processes, error handling, GUI's and distributed processing. There is a lot of material here not to be glossed over by newcomers. Functional programming requires a different way of thinking about structuring your code, and that new paradigm won't come quickly to most people.

One of the more-memorable paragraphs which strongly advocates for Erlang's implementation of concurrency is on Page 9….

Erlang and Functional Programming

"The recent success of Erlang is a success for functional programming, too, because it uses functional programming principles without making a big fuss about it: they are simply the right foundation on which to build a language with concurrency designed in from the start.

One of the prevalent myths in the community in the mid-1980s was that functional programming languages would be the only languages capable of working on the general-purpose parallel machines that were "just around the corner." It didn't turn out like that 20 years ago, but perhaps that's exactly what we are seeing now in the way that Erlang is being used to provide massive concurrency in server farms, cloud computing, and on the multicore processors inside all our computers, from laptops on up."

I highly recommend this book to you if you are looking at learning Erlang. It will guide you through most of what you need to know to get up and running.

I have been trying to get started on erlang for some years now. Could never get myself to go through the documentation available fully. Being new to functional programming perhaps was the biggest hurdle.

However thanks to this book, 2-3 days has given much insight. It gets started slow and then picks up a lot of momentum. I feel confident to start on my (mega) pet projects :)

Comments about O'Reilly Media Erlang Programming:

I have been using Erlang for quite a while in my line of work and was curious to see if this book would teach me anything new. It did! Erlang Programming is an excellent read for novice and experienced programmers alike. It covers the syntax and semantics of the language in depth, and explains how to think out of the box and get used to the "Erlang Way". The second half is dedicated to more advanced subjects.

What I especially liked about the book is that it is up to date with the latest R13 release and includes a section on the TypEr tool, a chapter on Erlang and Test Driven Development and how to interface Erlang with Ruby. It also has a chapter dedicated to the WxErlang library, a graphics package which was just released as part of the distro. The authors obviously worked closely with the OTP development team on what at the time of writing must have been undocumented features.

My favourite chapters, however, were those on Tracing Erlang based systems and on Style and Efficiency. The experience of the authors is truly reflected in these chapters, and they are worth the price of the book alone.

I warmly recommend this book to those interested in learning more about Erlang or interested in the foundations needed to build fault tolerant, soft real time systems. It is easy, entertaining reading. A must have in the bookshelf of a software professional!

Review. Erlang Programming.

Dave Pawson. UK.

'Different'. That's my initial reaction. I've yet to finish the book,

in fact I doubt I will finish it. So far I keep diving back to earlier

material for clarification, confirmation etc. It seems to be written

as a reference book, rather than a straight read. Practical it

certainly is, the examples are not contrived but seem to be drawn from

real life usage. I certainly didn't find them easy to follow without

working at them. That seems to apply to the rest of the book too. The

more you put into it (reading / studying) the more you'll get out of

it.

I figure the authors have been there and done that quite seriously,

since I keep marking passages with 'advice and experience', as if

they've been bitten and are passing on that information to the

reader. I'm quite impressed with the quality of the code. It appears

to me as the sort of code that is written on the fourth time round?

Get it working, realise it's rubbish, re-write, learn a bit more and

fourth time round the abstraction is about right, the code 'simple'

(wrong term) and flexible. Could be just my misinterpretation

though. I feel I could 'steal with glee' and gain significantly from

re-using their code.

Look out for 'dense' writing. By this I mean a simple passage that

I've read and moved on... until I'm missing something. When I re-read

the passage I get a little more out of it, then on third reading I

understand the content. I guess this is typical of an engineers

output. Concise writing without the flourishes found in less technical

writing. Try and recognise it and you'll get more from the book.

The quality of the content is high. The layout of the chapters (order

of presentation) I can't comment on as someone new to Erlang. So far

I'm happy with it.

All in all I like the book. It is doing what I wanted, providing a

good introduction to Erlang - in fact it leaves me quite intrigued!

From my experience, you are most likely to benefit if you have a

running Erlang system on your PC whilst you read, some of the

exercises will (for me) need more time and a bit more work to

comprehend the ideas behind the code, rather than just seeing the code

running.

All in all a good read, does what it says on the tin, as one of our

adverts says.
