Perl + fastcgi + nginx Build
Nginx + fastcgi is the most popular environment in PHP, then Perl will also have fastcgi it, of course, Today to build the next Nginx Perl fastcgi. Performance is no less than PHP, but now the popularity of Web programs PHP is not comparable to Perl, performance is no good, but s
This article focuses on the concept of Perl variables in the Perl syntax, where Perl variables are divided into scalar variables, array variables, and relational array variable 3 classes. Perl's variables are sensitive to size, such as: An,an,an is a 3-divided variable, but a variant of a different paradigm can use a uniform name.

Exercise 7.3: Implement a String method for the *tree type in Gopl.io/ch4/treesort (§4.4) to show a sequence of values for the tree type.Package Mainimport ("FMT" "bytes") Func main () {//definition array arr:=[...] int{6,2,1,3,4,5} var t *tree for I:=0;i Daily Go Language Bible-Interface Conventions Exercise 2
Goroutines and Threads:1. Dynamic stack:1) Threads have a fixed-size block of memory (typically 2MB) to stack2) A goroutine will start its life cycle with a very small stack, usually only 2KB, not fixed; the stack size will dynamically scale as needed2.Goroutine Dispatch:1) threads are scheduled with a hardware timer, slow2) Go is using its own scheduler, scheduling on the thread basis, does not need to enter the kernel context3.GOMAXPROCS environment variables can determine how many threads are
Exercise 8.8: Use Select to transform the Echo Server in section 8.3 to increase the timeout so that the server can automatically disconnect when there is no shouting in the client for 10 seconds.Reverb3.goPackage Mainimport ("Bufio" "FMT" "Log" "NET" "Strings" "Sync" "Time") Fu NC Main () {listener, err: = Net. Listen ("TCP", ": 8040") if err! = Nil {log. Fatal (Err)} for {conn, err: = Listener. Accept () if err! = Nil {log. Print (ERR)//e.g., connection aborted continue} go handleconn (conn)
Exercise 8.3: In the NETCAT3 example, Conn is a interface-type value, but its underlying true type is *net. Tcpconn, which represents a TCP connection. A TCP connection has read and write two parts, and you can use the Closeread and Closewrite methods to close them separately. Modify the main goroutine code of the NETCAT3, just close the part written in the network connection, so that the background goroutine can continue printing the data returned from the REVERB1 server after the standard inpu

Perl is very different in variables and data paradigms and C. However, its operator and C are almost identical, except for the example conversion operator type of C, the pointer reference operator *PTR and the layout memb
Perl is still less than that. Watching video is quite handy when getting started, just like a movie. I basically superor the teacher every episode I have read. I hope everyone will take a look at it.
Remember, learn to write more, can only see understand, only 5% is your, practice do one, there are 30% of you. Other if can according to the tutorial, writes oneself to want the procedure, only then 80% is yours.
Thanks again to superor teacher.

List module for columns in Perl, and list module for perl tools
There are some modules specifically used in Perl to Process List data, such as List: Util module. This module is included in the standard library and provides various efficient common List processing tools. Because it is implemented in C language, the speed is generally quite fast!

Here we will summarize the issues that need to be paid attention to when programming in the Perl language.
1. the hash value is not sequential, so the values returned by the hash function are all sort, rather than the status when the hash value is assigned. For example:
my %hash2=( ‘ten‘ => 10, ‘fiirt‘ => 1, ‘second‘ => 2, ‘third‘ => 3, ‘fouth‘ => 4);print keys %hash2;---result-----fiirtsecondthirdfouthten
Using the hash function each, the result is a

S/PATTERN/REPLACE/; # returns the Boolean value of whether the replacement is successful.
You can use capture variables, such as s/(\ w)/$1/
If the matching fails, no processing is performed.
2. delimiters
For delimiters without left or right, repeat them three times, for example, s //, s ###
