First, Introduction Since the advent of Ruby on Rails last year, interest in the Ruby programming language seems to have grown steadily. Rails has helped people see what Ruby is: A very decent, easy to learn and fun-filled language, even for the development of industrial-grade applications. Ruby is now almost the same

Learning a language, I think the most should first understand is how to build the operating environment of this language. If we know the language's running environment, we can find the IDE tools that match the previous development habits, and then take a look at the introductory examples to learn a language-related knowledge. At such times, a language should begin to get started. It is only a matter of time before the rest of the school can learn and practise. My

The use of Ruby on Rails in Linux can make it easier to maintain and develop Web applications, allow developers to focus more on the logical structure of the system, and configure the Ruby on Rails development environment before use, and the following small series will introduce Ubuntu 12.04 How to configure the Ruby on Rails development environment. Ubuntu 12.0

Programs are not run in a straight line, and the order of execution is influenced by some rules and some programming structures called control flows. Ruby's control flow has the following: Conditional execution (Conditional execution)-executes according to the authenticity of an expression.Loops (looping)-code that repeats together.Iteration (ite

In the past few years, the open source Web development Framework Ruby on Rails has created a small upsurge in the web world. Like many things in the software world, its role is somewhat exaggerated. Nothing is as magical as what people advertise it. But rails is at least as close to this altitude as it is, so it's worth studying for. Not long ago, people were asking whether rails would succeed. I have now maintained my views on the issue at that tim

BKJIA exclusive Article] There are too many slots on the Internet about the comparison between Ruby and Python, but I have not found any useful discussions, because we always argue about the functional differences between the two sides, it makes no sense to go on like this. In fact, both parties will have it. Otherwise, one party must have been wiped out by the other. BKJIA recommended reading: Advantages of Python Thread Programming over

To sum up simply a sentence:1. If you want to help him find a job as soon as possible, make money, recommend PHP.2. If you want him to be an efficient engineer, recommend Python.3. If you want him to fall in love with his job, recommend Ruby. Choice of Language: The programming language is very important, do not think that they are all Turing equivalence, use the same. In fact, good language gives you something beyond imagination. Here are some ide

The Fruit class in the previous section has two real variables, describe the type and state of the fruit. Until a custom inspect method is written for this class, we understand that it does not make a reasonable explanation for a fruit that lacks attributes. Fortunately, Ruby provides a way to allow real variables to always be initialized. Initalize method When Ruby creates a new object, it always looks f
