After the storm from blog to mailing list, roadmap of New groovy appeared. To some extent, this is a response to groovy is dead, which has been so popular recently. On the other hand, Mike spille, groovy's neighborhood, responded to the criticism of the New groovy feature in the form of a wiki document. This is the most controversial of all new features, of course: return/break/continue to behave inside closures like these statements work in other bl

. -A, -- all Do not ignore entries starting. 2. touch, cat, and less commands The touch command can create any type of files with a size of 0 in Linux. As a program developer, you can use the touch command to create files on a Linux Server: Syntax: touch Touch demo.txt Root @ devopscube :~ # Touch demo.txt Root @ devopscube :~ # Ls Demo.txt The cat command is used to view the content of a file, but the cat command cannot edit the content of the file. It can only browse the content of the file.

you omit Filehandle, STDOUT will also be regarded as a fixed Filehandle. before introducing the printf function, let's take a look at the characters that transform symbols in the printf function. Symbol% C characters% S string% D integer% F floating integer% H hexadecimal code% O octal codeExample: Printf ("chomod % d % s \ n", "711" "cgi"); the chmod 711 cgi is added with a line break and displayed on the screen. Command: Chop Syntax: chop ($ url)Description: Delete the last character.Example

The block in Ruby is generally translated into blocks of code, which seems a bit strange at first because there is no such thing in many languages. Actually, it's not bad.first-class function and Higher-order function The first-class function and the Higher-order function are concepts in functional programming languages that sound like high-end, but very simple. First-class functions refers to that in some languages, functions are first-class citizens, and functions can be passed as arguments.

the data file does not have any definite order. If we create an index of the name column, MySQL sorts the name column in the index, and for each item in the index, MySQL internally saves it a "pointer" to the location of the actual record in the data file. So, if we want to find the Peopleid (SQL command for the Select Peopleid from people WHERE Name= ' Mike ') that name equals "Mike" records , MySQL is ab

From: xuejinyoulan [add to my favorites] Source: it168What is a regular expression?A regular expression uses a special symbol pattern as a string in the expression format. It is mainly used to describe and parse text. ManyProgramRegular Expressions are ignored (or not used) by members (or even some good experts). I think this is a shame, because when we solve many problems, regular Expressions often make us feel comfortable. Once you have mastered it, you will find it can solve countless real-

of the reference type. Why is it a deep copy? If you look at the source code of the string type, you will know: // Indicates an empty string. This field is read-only. Public static readonly string Empty; The answer is that the string type is readonly. When the value of the string type is changed, the memory address will be re-allocated. Shallow copy: copy a new object to the object. Definition of shortest copy-only allocates a new memory address for the value type (or string. Deep copy: copy a

When using a prototype, you cannot pass parameters to initialize the value of a property through a constructor, which is annoying but not finished, and the real pr

1. Prototype chain inheritanceIn order for subclasses to inherit the attributes of the parent class (also including methods), you first need to define a constructor. The new instance of the parent class is then assigned to the constructor's prototype. functionParent(){THIS.name =' Mike '; }functionChild(){This.age =12; } Child.prototype =New Parent (); //child inherits the parent, through the prototype, forms the chain var test = new Child (); aler
