This is the definitive book on Erlang written by "Joe Armstrong the creator of the Erlang language The book is clearly written with lots of small examples and " Armstrong the creator of the Erlang language The book is clearly written with lots of small examples and for the beginning Erlang programmerErlang takes a little getting used to It is a functional language meaning that functions in general are unable to cause side effects For example variables are in one of 2 states their initial state is unbound their final state is has some value that can never "CHANGE ATTEMPTING TO PLACE A VALUE "Attempting to place a value a variable that already has a value causes an exception This aspect of functional programming makes it possible to write multi threadedmulti process applications without the problems inherent in multi threaded applications in non functional languagesThe basic data types in Erlang are functions atoms numbers lists tuples and strings which are actually lists of integer numbers List manipulation in Erlang is similar to that in Lisp lists are generally treated as a head and tail This is used by the Erlang way of defining functions functions are defined as a set of pattern matched expressions with code a This is a great book As others have mentioned before it is a bit chaotic at times with understanding coming only after Esperanza renace reading future chapters and with a few mistakes here and there but this is made up for by the depth of the material and the positive energy of the author present on every page If you can get through the tough parts you ll beewarded by a great explanation of how to build eliable systems based on immutable datastructures and message passing Excellent book The first book you should ead if you are learning Erlang The explanation is very clear without dumbing down the details A classic book like KR C but for functional and concurrent programming A book with big cons and big pros I think it will be easiest if I simply list the cons and the pros Let s start with the cons all of which I attribute to editors asleep at the wheel or on crack1 The book is laid out in a American Masters of the Mississippi Gulf Coast: George Ohr, Dusti Bonge, Walter Anderson, Richmond Barthe reader hostile manner topics are introduced completely out of order You ll be skipping around a lot to find in depth answers for anything2 The index is worthless Youe olling the dice when you try to find a particular topic Chances are good it s not in the index3 Many important items are in a 20 page section entitled 54 Miscellaneous Short Topics All Miscellaneous Short Topics All these topics could have been properly placed in appropriately titled sections elsewhere in the book4 The syntax of the language is seemingly andom to a newcomer You never know if a line will need to end with a period semicolon or comma By the time you Sitzungs-Berichte Der Gesellschaft Naturforschender Freunde Zu Berlin: Jahrgang 1893 (Classic Reprint) re done with the book you ll have figured all of this out But I never came across a section describing the language syntax5 Much of the text of the book is Armstrong tooting Erlang s horn I m glad he likes it but most of that should have been trimmed from the book6 There are a few errors in the source This is always painful in a programming book 7 Between the illogical structure of the book and the painfully unhelpful. Erlang solves one of the most pressing problems facing developers today how to writeeliable concurrent high performance systems It's used worldwide by companies who need to produce From Muslim to Christian Granada reliable efficient and scalable applications Invest in learning Erlang nowMoore's Law is the observation that the amount you can do on a single chip doubles every two years But Moore's Law is taking a detour Rather than producing faster and faster processors companies such as Intel and AMD are producing multi core devices single chips containing two four or processors If your programs aren't concurrent they'll onlyun on a single processor at a time Your users will think that your. Error messages from Erlang itself getting through the thing "CAN BE A PAINFUL EXERCISE8 THANKFULLY I VE ALREADY "be a painful exercise8 Thankfully I ve already a study of functional programming ie immutable data lambda etc I think this book would be a challenging introduction to the subject as it does not spend much time explaining the theory and practicePros1 Armstrong eally seems to enjoy showing off Erlang s features The enthusiasm is nice2 There are some good examples in the book3 By the time you e done you ll feel like you have a pretty good grasp of the language4 The language itself has a number of very interesting conceptual features The book does do a good job of presenting what is advantageous and uniue about ErlangIn all it s a decent book completely crippled by a complete lack of a good book editor Since there is now an O eilly book called erlang programming i d suggest book called Erlang Programming I d suggest a look at it instead O Reilly has good editorsStrangely I ve noticed a propensity for Erlang supporters to confuse criticism of this book with criticism of Erlang or even of functional programming in general itself Please do not make that confusion here An adeuate introduction to the language Erlang is an important language and it has enough unfamiliar elements to make it difficult to pick up without a guide This book deserves credit for being a clear approachable introduction to the syntax and core ideas of Erlang However he does not go as deep as I had hoped His description of the language itself is thorough but the chapters on OTP were elatively thin and I am left with a number of uestions about how to build and tune actual production systems with the Erlang toolset He
also doesn t 
doesn t any extra points for style I would The Afterlife of Little Women recommend looking at the other Erlang books that are available It is an excellent book I strongly advise anyone that wants to dive into Erlang toead this book It is well structured and covers the topics in an consise and joyful manner I especially like how it keeps it Domesticating Drink: Women, Men, and Alcohol in America, 1870-1940 real witheferences to Lord Byron at Harrow School: Speaking Out, Talking Back, Acting Up, Bowing Out real world cases Personally it makes me feel like I am taking a stroll down theabbit hole into the wonders of the Erlang world Perhaps the most challenging part of software engineering is striving to build something that is simple Simplicity to me means something that you can fully grasp intuitively ignoring the irrelevant And then use it to enrich your language and build on top of it This is also the premise of OOP but for many easons it s easy to get bogged down with classesmethods that end up doing too much My novice understanding of Erlang is that E I eally wanted to write a lovely Sisi: Empress on Her Own review of this not just because it s a prag prog book but also because I like the values espoused by the Erlang community I had hoped for a tour de force from the language s creator but instead I got a book I skimmed the last hundred pages ofSo what s wrong with it Half a dozen things but the crucial thing is that the focus of the book wanes as the book progresses In the early chapters there s aeal feeling of purpose but by the end you. Code is slowErlang is a programming language designed for building highly parallel distributed fault tolerant systems It has been used commercially for many years to build massive fault tolerated systems that un for years with minimal failuresErlang programs un seamlessly on multi core computers this means your Erlang program should The Art of Slow Writing: Reflections on Time, Craft, and Creativity run a lot faster on a 4 core processor than on a single core processor all without you having to change a line of codeErlang combines ideas from the world of functional programming with techniues for building fault tolerant systems to make a powerful language for building the massively parallel networked applications of the futureT. Almost feel despondent as the author tries to motivate himself and you to try the best parts of the platform The chapter on OTP is a c Erlang is an amazing programming language This book is not the best if youe learning functional or parallel programming you should know both paradigms before eading this book also you should have programmed many FUNCIONALITIES IN JAVANET OR ANY OTHER SO COMPLETE LANGUAGE in JavaNET or any other so complete language it s handy if you e learning Erlang or modular programming It s easy to get stuck so take your time Statistical Inference reading it It was a while since I wrote my first post Theeason is that I m eading books parallel and it takes time to finish one in 100% Although I m digging trough some interesting materials since October which surely deserve mentioning here the book I want to write about today hijacked my time pritty well last month making me ead it from the cover to cover in no timeSo here it goes another book from the Pragmatic Bookshelf Programming Erlang Software for a Concurrent World by Joe Armstrong I must admit that it is another position from this publisher that I ve fallen in love with ight away so expect only kind words from this articleSo what areas does the book cover Basically the fallowingErlang as the languageConcepts of the functional programmingConcurrent programming using the Erlang Actor ModelOverview of interesting and sophisticated Erlang librariesIn contrary to the first book I wrote about Programming Erlang is ather long as it contains total of 519 pages That number can be intimidating Personally I m scared of books longer than 250 pages That was not the case hereFortunately after Tigers in Normandy reading through the Contents my fears has gone away Introducing Erlang takes no than 150 pages Additionally it seally well illustrated with eal life examples so both new language and concepts of the functional programming comes in natural and pleasant process Additionally code you are guided trough and which you will write fallowing "The Book Touches Undoubtedly " book touches undoubtedly subjects like diagnosing mpg file eading tags from mp3 file streaming multimedia content via web or implementing simple concurrent communicatorSo if that s all what s on the next 370 pages you may ask More knowledge I answer But to be precise there are two subjects covered in est of the book serious concurrent Erlang programming and tools for serious concurrent Erlang programming Knowing new language is one other knowing how to use it to benefit from all its possibilities is the other After learning you a new great functional language Joe Armstrong takes you to a trip through newest concurrent programming approaches and techniues illustrated with even interesting eal world examplesOf course there is not book that will make you a specialist in new language in two weeks and no one should have any doubts on that What Programming Erlang gives you is a wide entry into the Erlang world and preparing you to use it in your serious projects ight away All you need is a little bit goggling and coding coding and codin.
