Useful tool, good background reference

Simply the best book on numerical calculations. The source code is similar to recipes in cooking. Never taste a recipe itself... but start cooking.

keeps up with latest C#

C# is still a relatively new language. But here Wiley/Wrox is already on the third iteration of this book! Very up to date, with the latest C# capabilities. Just as importantly, the book has extensive coverage of how C# integrates into .NET. Specifically including how to make Microsoft Windows Forms, and how to make dynamic web pages by combining C# with ASP.NET's components. Also of interest to some of you will be the sections showing how to use C# to connect to a SQL engine, like Microsoft's SQL Server.

In fact, one key message of the book is that C# derives a lot of its value from being tied into .NET and its associated family of packages. The book has over a thousand pages of details, but this take home idea concisely conveys much of the authors' intent.

As the side note, the C# Collections include what Microsoft calls Dictionaries. As the authors explain, this is a data structure that is more generally known as a hash table or map. [Cf. Knuth's "Art of Computer Programming", vol 3.] Yes, there is a .NET class called Hashtable. But you might think that in the interests of conforming with a straightforward industry usage, Microsoft might have dropped "Dictionaries".

Title: Oracle PL/SQL Programming, Third Edition
Publisher: O'Reilly
Authors: Steven Feuerstein
Rating: 3/5
Customer opinion - 3 stars out of 5
Not recommended for beginners

1.this book doesn't even list triggers in the table of contents, which means that triggers were not included in that book at all!! 2.i dont know why, but the examples in the book were so different in every page and every chapter. it was really hard to know what the examples were all about. 3.table contents and actual contents do not match sometimes. the author mixes oracle8 features with oracle 7 features while explaining about oracle7 features, which only gave me confusions. 4.the only thing that attracted me was the tips that helped me pretty much.. In conclusion, if you are a beginner to pl/sql, please do not buy this book.

Title: Perl Cookbook, Second Edition

A Great Resource!

The "Perl Cookbook" condenses into code algorithms that are both beautiful and helpful. Paired with the "Programming Perl" book, which despite problems of organization is undoubtedly the best Perl reference, the cookbook is simply indispensible for both the serious Perl programmer and anyone who wishes to learn how to write Perl naturally.
Every language has a natural idiom; even COBOL. Perl, having convenience so strongly in its genesis, is not very similar to its predecessors in many ways, and along with solutions to individual problems what one learns from the cookbook is how a Perl programmer would write such a program. You learn twice reading these answers: not only how to solve your problem (how do you read a file line by line in reverse? how do you trap signals in your program?) but also what the natural idioms are which both simplify your code and make clearer to you how Perl works.
I reviewed "Programming Perl" and had reservations about it: I have none about this book. It is not a reference to solve all your questions about the language--buy "Programming Perl" for that. It is not a tutorial--for that, get "Learning Perl". What it is is a distillation of some smart people's work in Perl; well-explained, clearly laid out, and highly informative in every area a programmer is likely to work in. Buy it if you love Perl.
