I'm currently a very casual user of Apache Mahout, and I'm considering purchasing the book Mahout in Action. Unfortunately, I'm having a really hard time getting an idea of how worth it this book is -- and seeing as it's a Manning Early Access Program book (and therefore only currently available as a beta-version e-book), I can't take a look myself in a bookstore.
Can anyone recommend this as a good (or less good) guide to getting up to speed with Mahout, and/or other sources that can supplement the Mahout website?
I saw people asking about best book for learning spring, and I came across manning.spring in action was recommended most of the time so I decided to give it a go.
The thing is the author offers some pretty reasonable explanations, puzzle by puzzle it gets in your head, than you just need to code it and you're done, you get it(this is how I work don't know about the others).
When it comes to the code its very disapointing, I went trought the Knight example like 2 or 3 times by now and I see its incorrect in the book, I mean its hard already for people eager to learn and why not a note somewhere in the book like pseudo-code or something.
The knight example in the first chapter is missing two classes QuestFailedException and HolyGrail I mean other people must have noticed this, why is everyone recommending this book without saying at least it has some errors(like many others do), was anyone actually been able to compile and this first chapter example?
Hi, having taken a look at a few textbooks that discuss numerical methods and C programming, I was gladly surprised when browsing through "programming in C with numerical methods for engineers" by Rojiani. I understand of course it's important that one need to have a solid background in numerical methods prior to try implementing them on a computer.
I would like to know if someone here has been using this book and if possible point out strengths and weaknesses of this textbook.
Thanks a lot...
6.1.4 Describe an algorithm based on breadth-first search for finding a shortest
odd cycle in a graph.
6.3.5 Describe an algorithm based on directed breadth-first search for finding a
shortest directed odd cycle in a digraph.
what is most importent is that it must be a directed graph not necessary bfs but must be the shortest directed odd cycle!!!
Question was taken from "Graph Theory" by J.A. Bondy and U.S.R. Murty
thanks in advance!!!
Hi, can someone please tell me where to find the example codes used in this book:
Sitepoint The Php Anthology 2nd
edition
? Ive been looking for this since yesterday. Thanks for answering.
All,
I'm going through the Friedman & Felleisen book "A Little Java, A Few Patterns". I'm trying to type the examples in DrJava, but I'm getting some errors. I'm a beginner, so I might be making rookie mistakes.
Here is what I have set-up:
public class ALittleJava {
//ABSTRACT CLASS POINT
abstract class Point {
abstract int distanceToO();
}
class CartesianPt extends Point {
int x;
int y;
int distanceToO(){
return((int)Math.sqrt(x*x+y*y));
}
CartesianPt(int _x, int _y) {
x=_x;
y=_y;
}
}
class ManhattanPt extends Point {
int x;
int y;
int distanceToO(){
return(x+y);
}
ManhattanPt(int _x, int _y){
x=_x;
y=_y;
}
}
}
And on the main's side:
public class Main{
public static void main (String [] args){
Point y = new ManhattanPt(2,8);
System.out.println(y.distanceToO());
}
}
The compiler cannot find the symbols Point and ManhattanPt in the program.
If I precede each by ALittleJava., I get another error in the main, i.e.,
an enclosing instance that contains ALittleJava.ManhattanPt is required
I've tried to find ressources on the 'net, but the book must have a pretty confidential following and I couldn't find much.
Thank you all.

I have a Computer Science degree (long2 time ago) .. I do know Java OOP but i am now trying to pick up C++. I do have C and of course data structure using C or pascal.
I have started reading Bjarne Stroustrup book (The C++ Programming Language - Special Edition) but find it extremely difficult esp. some section which i don't have exposure such as Recursive Descent Parser (chapter 6).
In terms of the language i don't foresee i have problem but i have problem as mentioned cos' those topic are usually covered in a Master Degree program such as construction of compiler. I just bought a book called C++ primer (Stanley Lipmann) which i heard it is a very good book for C++. Only setback is it's of course no match with the amount of information from the original C++ creator.
Please advice.
Thanks.
I am completely new to programming and starting my education with visual basic 9 and SQL.
I have read Visual Basic, in easy steps, 2nd edition by Mike Mcgrath. Although it was very easy to understand, it only gave me an introduction to learning VB. I'm looking for something more in depth, albeit for a beginner.
I've read through the questions with a VB and book tag. Unfortunately, most of what I've found here references VB 6 and VB 8. Any recommendations? I cannot afford to create a library or college at the moment. So, I need to make sure that what I do buy counts.
Thanks for any suggestions!
I'm a programmer, and have completely forgotten all the advanced engineering Math I studied ~20 years ago at school. I now have an urgent need to learn about Modelling and Simulation. Though the present context is Disease Modelling, I'm not sure if there's such a thing as 'general' modelling and simulation... with concepts / techniques / algorithms that could be used in just about any domain (and not just limited to biology, finance, trade, economic, weather, etc.)
Would you have any recommendations that are easy to read by a semi-Math-literate programmer?
Basically, I cannot afford to drown myself in too much Math and theory behind M & S, hence this post.

I am a rather oldschool developer with some basic knowledge of software design principles and a good background on classic (gof) design patterns. While I continue my life as such I see lots of strange buzzwords emerge:
Aspectoriented Design, Componentoriented Design, Domain Driven Design, Domain Specific Languages, Serviceoriented (SOA) Design, Test Driven Design, Extreme Programming, Agile Development, Continuous Integration, Dependency Injection, Software Factories ...
Is there good book around that I can take with me on a roadtrip while it is taking me on a trip through all (most) of the above, delivering an 10,000 foot view on modern software archiceture and desing principles and approaches.
GUYS I need to know abt the book which is best book for a professional to improve his concept
it must be objective
if sm1 have plz send it to [email protected]
I own and have read most of this book, a while back. Now I'm about to embark on a pretty large project and was wanting a refresher. Anyone got a recommendation of something similar that has a focus on C#/.NET. I know the principles remain, but if only for my readability.
I have a simple structure, it's just an array of model's objects.
For example, it's a users with books.
@books = Book.find(:all, :include = :users)
I need to check, does user have a book?
I have written a helper method:
def has_book?(user_id)
@books.select{|b| b.user_id == user_id}.any?
end
Then, i need to get only books from selected library
def in_library(n)
@books.select{|b| b.library == n}
end
I have tried to make custom Array class:
class BooksList < Array
def initialize(books)
self << books
end
# its my custom methods
def has_book?(user_id)
self.select{|b| b.user_id == user_id}.any?
end
def in_library(n)
self.select{|b| b.library == n}
end
end
It works, but i have only one problem. I can't access Book's assotiated object (user). So i can't write:
@books = BookList.new(Book.find(:all, :include => :users))
@books.first.user.id # it says undefined method `user' for #<Array:0x104b43e08>
I am creating a website that is to have a book style layout. So you turn the pages and they fold over. I have this working in JQuery for images.
What I am looking to do is have clickable links on the pages so that I can jump to a page further in the "book" or even to another site.
Does anyone know the best way to go about this or have any examples to help out?
Thanks

Hello!
I'm looking for a source of information about Microsoft Silverlight to begin practically efficient programming custom functionality applications. I want to pretend just for now that I don't need any ideologically correct refresher (SL tips, top patterns, VS tutorials :) and etc.). Basically, what I want is a reference kind e-book, where I could find any practically relevant info outlined in a minimalistic manner.
If you do remember something fitting the above description, I ask you to give me a hint.
Thank you very much!
Hi there
I'm cs student and we did some unix programming at school, but most of use are using windows os. I have decided to go on ubuntu. Besides installing ubuntu and using it, what book will teach me the "must" things to know about *nix OS?
If you could go back in time and tell yourself to read a specific book at the beginning of your career as a developer, which book would it be?
I expect this list to be varied and to cover a wide range of things. For me, the book would be Code Complete. After reading that book, I was able to get out of the immediate task mindset and begin to think about the bigger picture, quality and maintainability.
Can someone provide recommended reading, website resources or best practices to follow when programming with C. I am a proficient software developer with strong skills in Java and PHP.
Is there standard libraries these days which people use? Like what spring is to java? And standard design patterns for managing memory or even standard libraries for that fact?
I want to write solid, maintainable C programs.
GO THE RED PILL! :P
Hi there,
yet another question for recommendations for a book on Silverlight.
I look for a book that covers the UI and styling and, if possible, custom drawing and graphics. Very important for me is the style of the book - it should focus on the actual programming and not on where to click in Visual Studio to get things done.
Let's take a fictional example for proper usage of the DataGrid control:
Bad: To use the data grid, drag it from the toolbox onto the control. You can change the background color by clicking on “Background” in the properties. To define custom columns, click on columns and edit them in the configuration window that opens.
Good: To use the DataGrid, you need a reference to the blah dll and declare the namespace in the XAML like this (blah), the data model should be like blah and if you want to define how the columns look like, you need to define them like this (more blah). And if you want to do this in C# because you for whatever reason aren’t able or willing to use XAML, this would look like blah.
Bonus points for coverage of topics like how to manage resources (images/fonts) and internationalization. There are quite some snippets on how to do that on the internet but somehow each of them looks like they work but are not a proper way of doing it.
cheers

I am the technical director at a startup, and I will eventually be tasked with implementing a "real" system architecture when we hire more programmers. Right now our clients are small enough, and it is just me, so documented deployments, source control, unit tests and quality assurance servers are non-existent. Eventually I will need to devise a work-flow and architecture patterns for the majority of the work we will do (e-commerce). If I posted an architecture diagram, and asked for feedback, would that be a misuse of the Stack Overflow system? I don't want to get into that battle of "hey, don't ask us to do your job for you", but the reality is that any programmer who eventually moves into this realm will have to figure it out with feedback from other developers. HighScalability.com is what comes to mind when I think about this sorta thing in terms of the knowledge I need. So if this is not the right kind of forum for that, then any book recommendations or white papers you can recommend would be appreciated.
What is the best book for a student learning about concepts such as NP-hard, NP-complete and P=?NP?
I've already got the CLR but it doesn't really cover these particular topics as thoroughly.
