Data Structureis a collection of data elements that are organized in a way that can be numbers, characters, and even other data structures. Python's most basic data structure is sequence (sequence): 6 built-in sequences:lists, tuples, strings, Unicode strings, buffer objects, and Xrange objects. Comparison: List of the differences between the tuples in Erlang and Python:1. General Operation:The Python list is more like an array in C, but more flexible

Recently, I started to access Erlang, which is deeply attracted by it. Of course, I have to have an environment for learning. I have installed the Erlang development environment without hesitation. The installation is very simple. Download The Source Code directly. The traditional three-step installation: ./configure./makesudo make install The installation is successful. The installation directory is/usr/l

A brief description of OTP in Erlang and a brief description of ErlangOTP OTP contains a set of libraries and implementation methods to build large-scale, fault-tolerant, and distributed applications. It contains many powerful tools to implement H248, SNMP, and other protocols, the core concept is OTP behavior. It can be seen as an application framework that uses callback functions as parameters, similar to a J2EE container. The callback function is r

Original blog address, Http://www.linkedin.com/pulse/garbage-collection-erlang-tianpo-gao?trk=prof-post.This article will simply describe the garbage collection of Erlang, which is not an in-depth discussion.When performing a partial garbage collection, the garbage collector only recycles the younger generation and moves the old generation to the old-time dedicated heap. When an

WhatsApp has used Erlang in the production environment to run to 96GB memory stand-alone 3M long connection, participate in: WhatsApp Erlang world. After all, the business level can reach WhatsApp that very little, now only tens, single too many hanging one too much impact, and there is no multi-line access, each room has to throw so several machines, so 1M can meet the requirements.Erlang has a natural adv

Recently, Erlang + MongoDB has been used in the company's webGame project. there is no way to learn about the project. To learn this, you must have an environment at least. Today, we will record it by setting up the development environment, and we will still develop it under ubuntu. By the way, if you do development, you 'd better choose linux, because there are many...

Erlang distributed issues that should be paid attention to between linux and windows systems-Linux Enterprise Application-Linux server application information. The following is a detailed description. If nothing happens, test Erlang distribution between two machines. One is Windows XP, and the other is redHat9. Without detailed documents, you can find it and record it. 1. First, the implementation of dis

Rebar is a follow ERLANG/OTP principle Erlang Project builder, using it to reduce the build standard ERLANG/OTP Project architecture configuration, and can be easily compiled, tested, published Span style= "font-family:arial; Background-color:white; " > Erlang application. More powerful, rebar Provide

There are two common types of network communication: Text communication and binary communication. Text communication between php and erlang is relatively simple. We will not discuss it here. We will mainly discuss how php and erlang implement binary communication. Communication Example erlang code:-module (server).-export ([start0]).-define (UINT, 32unsigned-litt

The module is the Basic code unit of Erlang, and the Erl file is compiled with. Beam as the extension, with the UTF8 character set, and the. erl file as shown below:-module (module name, the same as the file name of the storage module)-export ([number of method name/input parameter])Method1 ({a,b,c})->a*b*c;MEHTOD2 ({d,e})->d-e.There are two types of module properties: predefined and user-defined.The data type used in

Erlang uses some common parameters and commands of hipe SASL Monitor, which are recorded in this memo. Compile and enable hipe (High Performance Erlang) What is hipe? The Overlord has a description in the phrase "Erlang's hipe is equivalent to JIT. According to the language evaluation, hipe supports 2-3 times faster in pure Erlang operations, this performance

The module is the basic unit of code for Erlang, and the Erl file is compiled with the. Beam as the extension, with the UTF8 character set, the. erl file is indicated as follows:-module (the module name, same as the file name of the storage module)-export ([Method name/number of input parameters]) Copy Code code as follows: Method1 ({a,b,c})->a*b*c; MEHTOD2 ({d,e})->d-e. There are two types of module properties: predefined and

The zebra puzzle is a typical constraint satisfaction problem (CSPs). Sudoku, Magic Square also belongs to CSPs problem. The language features of Erlang's list parsing allow it to solve such problems in a way that is very close to the natural language: it does not need to consider the process-solving steps to describe the constraints, and the Erlang interpreter matches the answer through a domain search. Someone has also used

Nothing to do, just between two machines test Erlang distributed example, a station is WindowsXP, a set of REDHAT9, no detailed documents, their own groping for success, recorded.1. First, the implementation of distributed Erlang provides its own security mechanism to prevent unauthorized access to the Erlang system. When an
